All too often presses are installed bysimply setting them in place on theshop floor with no consideration forproper installation. Special foundationsare sometimes used to provide ad-equate support, especially with largertonnage presses. When used withoutproper support, a multitude of prob-lems can occur, from unwanted vibra-tions to premature wear of press com-ponents to die failure, etc. Due to theexcessive shock and vibration causedby the operation of the press, isolationmaterial such as felt, rubber and com-posite have sometimes been placedunder the press feet, and shims usedfor leveling (see figure 1).

This is a step in the right direction,but does not address the problem offast, easy, accurate leveling and align-ment of the presses, nor of maintainingalignment. For this reason the pressmount was developed to provide bothease of leveling and alignment, as wellas vibration isolation (see figure 2).

This development has provided costsavings for metalworking operationseverywhere. The performance of a

2. Stamping impact and snap-through forces are present to somedegree in all presses and can be par-ticularly troublesome when higherspeed machines are used for blanking.The rapid rate of rise of force as thestock is contacted by the punch movesthe press crown upward and the beddownward, stretching the press uprightsin the process. At maximum capacity,the uprights of a press could bestretched to their allowable limits. Whenthe work material fractures, the oppo-site action occurs with the press crownmoving downward and the bed upwardto its original position, and because ofthis inertia, slightly beyond. This reac-tion is called snap-through shock. Theseforces are magnified by any misalign-ment condition which exists within thepress. Both the stamping impact andsnap-through forces can be greatly re-duced by proper leveling of the press,thus assuring proper alignment of presscomponents. Press mounts are veryuseful for controlling these forces andassuring symmetrical loading of thepress structure, thus greatly enhancingcomponent life.

press is greatly affected by how it isinstalled. The performance of otherequipment, as well as personnel, arealso influenced by how presses areinstalled. Presses should be supportedin such a manner that the shock andvibration generated in normal opera-tion does not transmit into surroundingareas, thereby disrupting precisionmachining work and/or contributing topersonnel fatigue.

Press mounts have provided a wayto allow presses to perform at optimumlevels, while reducing the cost of instal-lation, operation and maintenance.Other cost savings include fewer scrapparts and less building damage to floors,foundations, etc.

In order to perform to design speci-fications, presses must be supportedadequately to maintain alignment andcritical relationships between press andfeed equipment.

The support system for a press mustbe capable of dealing with:

1. Static loads (dead weight of thepress)

2. Stamping impacts and snap-through forces

3. Slide inertia forces

4. Rotating out-of-balance forces

To determine whether or not a pressis a good candidate for the use of pressmounts, let’s briefly examine each ofthe four items listed above.

1. Static loads are the forces seenat each mounting point with the press inoperating position, but completely atrest. Most presses have four mountingpoints, but are constructed so that theweight is not evenly distributed amongthem. Usually the rear feet are fartherfrom the center line of the slide travelthan the front feet. Also, flywheels anddrive equipment on mechanical pressesare located on one side or another. Thisuneven distribution of weight must betaken into account when designing anysupport system. UNISORB®

QuantumPM™ Press Mounts make it possible tocompensate for unequal weight distri-bution by allowing adjustment of load-ing among the press feet.

3. Slide inertia forces result fromacceleration forces acting on the slideand are an extremely important consid-eration in the design of a press mount-ing system. They act primarily in thedirection of slide travel and tend toalternately lift the press from its sup-porting surface and push it back into itssupporting surface. In some high speedpresses it is possible for these forces toexceed the dead weight of the press.This condition establishes a limitationas to whether or not a press should bemounted on freestanding mounts. Ma-chines which are manufactured withdynamic balancing equipment do nothave this problem, and can safely bemounted on press mounts. Older highspeed presses should be securelybolted down, and are good candidatesfor isolated foundations (see figure 3).

4. Rotating out-of-balance forcesresult from crankshaft imbalance andproduce a rocking of the press about itsmounting points. This problem is usu-ally found in older presses which do nothave dynamic balancing equipment,and which are being operated at highspeeds. In cases like this, proper actionmust be taken to restrain the press.When this condition exists on a press itis possible to predict by calculation theamplitude of the rocking motion that willoccur if sufficient engineering data canbe obtained on the press. Otherwise, astiffer than normal installation must befurnished to minimize the rocking mo-tion. This condition also is well suited tothe isolated foundation approach.

Anytime a press cannot be mountedsafely on press mounts due to any ofthe above conditions, UNISORB® of-fers the perfect solution. UNISORB®

Inertia Block materials, used in con-junction with a well engineered founda-tion with proper anchoring, will reducethe vibration and impact problems as-sociated with the operation of thesemachines, while maintaining the rigid-ity needed for proper support. In some

cases presses have been mountedusing both press mounts and inertiablocks, thus providing ease of levelingwhile further tuning out vibration prob-lems. Contact UNISORB® Engineeringfor more information about the inertiablock isolation materials.

In lieu of constructing an isolatedfoundation, UNISORB® isolation padscan be placed under the press feet, andthe press securely bolted to the floor,with leveling accomplished by the useof shims. UNISORB® Vector AnchorBolts, together with either UNISORB®

V-1® Non-Shrink Machinery Grout (ce-ment-based) or V-100® Epoxy Grout,can be used to anchor the press feet tothe floor. Contact UNISORB® Engineer-ing for more information on these fineproducts.

By utilizing press mounts wheneverpossible, anchor bolts, steel plates,shims and grouting materials can beeliminated, thus saving time and money.Any savings in labor and down time canbe considered to be significant finan-cial gain. These savings also can be

realized any time a press is relocated.Other savings which can be attributedto the use of press mounts are relatedto reduced maintenance of presses,dies, foundations and floors.

Two very important design consid-erations should be taken into accountwhen press mount evaluations and se-lections are made:

A. Press mount construction

B. Isolation pad materialselection

A. Press Mount Construction iscritically important because of thetremendous pounding inflicted uponthe mount during press operation.UNISORB® has optimized the balancebetween the high quality and strengthof ductile cast iron and structural steelfor its housing construction. The duc-tile cast iron is used on the smallermounts, while the larger mounts utilizethe structural steel components. Theductile cast iron offers the best combi-nation of strength and economy for our

Due to the necessity for flexibility ofsize and shape, the PM-261 modelsand larger are manufactured usingstructural steel. All the UNISORB®

Quan-

tumPM™Press Mounts have also main-tained the popular design feature of thespherical dimple in the impact plateunder the adjusting bolt to allow forangular correction for uneven floors. Forthe above reasons UNISORB® has main-tained its position as the most versatilesupplier of press mounts in the industry.

B. Isolation pad material selec-tion is paramount because it deter-mines the degree of proper vibrationisolation and environmental confor-mity which may be achieved by usingpress mounts. The design and con-struction of UNISORB®

QuantumPM™

Press Mounts provides the capabilityof choosing from a variety of isolationpad designs. These products are se-lected on the basis of their individualcharacteristics to meet your exactisolation needs. This flexibility pro-vides the opportunity to maximize vi-bration isolation and take into ac-count shape factors, environmentalconditions, spring rates, etc. There-fore UNISORB® is not restricted tothe use of any one type of pad mate-rial. UNISORB® elastomeric pads aremolded to exacting specifications toachieve optimum shock, damping andvibration control. UNISORB® Titan™Shock Pads provide excellent vibra-tion control and damping, especiallyunder extreme loads and high shockapplications. A combination of Elas-tomeric Pads together with Titan

Shock Pad inserts offer the perfectsolution to solving the vibration/isola-tion problems on larger presses (seeFigure 5). UNISORB® ElastomericPads are impervious to fluid absorp-tion and provide excellent isolationand damping. The high quality moldedcompound is superior to industrialneoprenes in oil resistance and damp-ing. Urethanes and other elastomersare also available, if needed, to meetthe special requirements of the Foodand Drug Administration and the U.S.Department of Agriculture.

INSTALLATIONPROCEDURES

1. Clean floor, removing all oil, greaseand debris.

2. Bring press into location and raiseit sufficiently to allow mounts to bepositioned under the mounting feet.

3. Remove the leveling bolts frommounts. Keep each leveling boltand mount together as a set so thestamped number on the housingand the bolt head match.

4. Position mounts (with bolt holesaligned with holes in press feet)and insert leveling bolts throughbolt holes in press feet and screwinto bolt holes in mounts.

5. On the PM-61 and PM-81 seriesonly, adjust each mount with theleveling bolt so the pad extendsbelow the mount housing approxi-mately 1/4". (All other mounts willautomatically be positioned simi-larly.)

6. Lower press onto mounts so allmounts accept uniform loading.

7. After 20 minutes (allowing the pressto “settle in”) locate the mount hous-ing closest to the floor and elevateit to 1/4" off the floor. Level thepress by adjusting the other mountsusing the first mount as the point ofreference. On large presses it maybe necessary to assist lifting thepress by external means while ad-justing leveling bolts. On the PM-81 series mounts the maximumamount of pad showing below hous-ing should not exceed 5/8".

8. The torques on the leveling boltsshould be relatively equal, signalingeven load distribution.

9. Add flat washers if necessary toadequately cover holes in pressfeet. A lock washer may also beadded if desired.

10. Tighten nuts, thus securing pressfeet to mounts.

UNISORB® provides vibration analy-sis service as part of its overall engi-neering assistance program to meetevery customer’s machinery installa-tion need. Our engineers are thoroughlytrained in the use of state-of-the-artvibration analyzing equipment and areexperienced in analysis of technicaldata collected for virtually all machin-ery shock and vibration installation prob-

lem. Solving difficult machinery instal-lation problems by providing compre-hensive engineered solutions is ourprimary mission.

UNISORB® engineers have per-formed vibration surveys in the field formany years and have identified thedominant frequency ranges typicallyfound in shop and plant environments.This information has guided UNISORB®

in the engineering and development ofits Press Mounts in providing the properisolation from these troublesome fre-quencies. The floor/soil system re-sponse to externally generatedvibrations influences the effectivenessof any isolation system and must beincluded in a complete analysis.

Ambient vibrations are detected byusing highly sensitive seismic acceler-ometers. These devices are capable ofmeasuring the entire frequency spec-trum, including the typically troublesomelow frequencies and low amplitudemovements which may affect perfor-mance of precision machinery.

“Smart Mount” analysis also pro-vides a means of monitoring ongoingchanges in the press or its mountingsystem for the future. Once base linedata has been established for a givenpress, subsequent “check ups” areeasily performed (without down time)to verify operating conditions or de-tect potential problems.

using equipment already owned bythe user) provide an “up and running”look at the forces seen by each mountincluding how these forces are beingresolved. This technique is more costeffective and accurate than “steadystate” or static load analysis in assur-ing optimal mount usage.

Special mount modifications or“single purpose” analysis equipmentare not required as the collection ofdata simply requires the applicationof a vibration transducer to an exte-rior mount surface. The mounts donot require any modification whatso-ever although transducer mountinglocations for permanent transducerattachment can be provided by thefactory for applications where mountaccessibility is limited.

UNISORB® expertise in perform-ing field evaluations and analyzingvibration signatures from all types ofrotating and reciprocating equipmenthas lead to the development of Ad-vanced Dynamic Analysis Techniquesfor determining actual press operat-ing conditions and proper mount ad-justment. By comparing vibrationspectra from individual press mountsit is possible to assure that the reso-lution of dynamic forces generatedduring operation are symmetricallyresolved by the mounting system. Thisimportant breakthrough in analyticaltechniques has provided an excellenttool to provide an even better envi-ronment for the press being installed.
