He wants held to a minimum the amount of downtime chargeable to regrinding and die set maintenance and repairs. He also wants scrap held to a minimal level. LEMPCO’s Ball Bearing Die Sets offer him this opportunity under a general heading of “accuracy.” Because a LEMPCO Ball Bearing Die Set is so accurate, there is less die wear, less scrap, less chance of seizure. These are profit factors. Also, less time consumed fitting in the die shop means cost reduction, which can result in more favorable pricing. The die maker also should know this because such a saving makes PRECISION ROTAINER® PRECISION RETAINER him more competitive. Cost records show that from 30% to 50% of the die maker’s time is consumed at the bench-fitting, mounting, aligning. The accuracy of a LEMPCO Ball Bearing Die Set reduces this time. Then there’s the ease of assembly and disassembly offered by a LEMPCO Ball Bearing Die Set. How many times are the punch holder and die holder assembled, disassembled, reassembled before a new set of dies is ready for trying? Time consumed, times the number of personnel involved, times the labor cost, can represent important money. If you can reduce this amount substantially, as you can the LEMPCO ball bearing way, then why not take advantage of your opportunity? 2 GENERAL INFORMATION LEMPCO’s Ball Bearing Die Set has paced the precision needs of production engineers demanding finer parts tolerances, longer die life and minimum down time for maintenance. LEMPCO’s precision quality ball bearing die set consistently has met these needs by matching improvements in design, materials and manufacture with demand. LEMPCO offers a Precision Ball Bearing Die Set for even more accuracy in operation, even smoother performance, more resistance to wear, longest die life, even more customer convenience. This results only from years of experience in the designing and building of die sets solely to the highest precision level available to industry. PRECISION OFFERS MORE LOAD CAPACITY The tiny ball bearing in a Rotainer® illustrates the rigid quality control program under which LEMPCO die sets are manufactured. It has been tested for sphericity, hardness, elasticity and dimensional tolerance. It is in a given set because every bearing in the same Rotainer® has passed all tests. The Precision Rotainer® sleeve is an even tougher alloy for additional wear resistance. A LEMPCO die set of the Precision design provides longer operating life and smoother performance through increased load capacity and resistance to adverse forces. The Precision Rotainer® sleeve is a silver color with blue stripes for quick visual identification. BALL BEARING LINE INCLUDES A COMPLETE ASSORTMENT OF GUIDE POSTS AND BUSHINGS Three kinds of guide posts for Ball Bearing die sets are offered: the straight type for most die set assemblies such as standard stock sets; the removable for quick release of the post to expedite disassembly; and the shoulder post for special die set construction where it is considered desirable to through bore both die holder and punch holder to a single diameter. Bushings for Ball Bearing Assemblies are offered in four types: the press fit steel sleeve with which stock sets are equipped as standard; the steel demountable shoulder bushing: the steel demountable boss bushing; and the steel demountable shoulder guide post bushing. All LEMPCO Ball Bearing Guide Posts, Bushings and Rotainers are completely interchangeable without any necessity whatsoever for select fitting of any kind and, if mounted in accordance with the boring and assembly instructions, do not require any grinding, honing, lapping or any other modification of any kind. PLAIN BEARING USERS HAVE A FULL CHOICE OF STOCK AND CUSTOM SETS AND ACCESSORIES In addition to the ball bearing line, LEMPCO offers plain bearing design die sets. In this catalog, you will find a complete dimensional description of all ball bearing and plain bearing stock die sets. LEMPCO offers three types of plain bearing guide posts: straight type, flanged demountable to expedite disassembly of the completed die for repairs; and the shoulder guide post. Plain bearing bushings are available to LEMPCO customers. Your choice can be made from five types of Precision demountable, bronze, bronze plate and steel; five types of Precision press fit, bronze, bronze plate and steel; five types of shoulder guide post bushings, bronze, bronze plate and steel; and three designs of demountable bosses and boss bushings. The components are available to you as constituent parts or already assembled into complete stock, special or special purpose die sets. LEMPCO’s Die Set Catalog offers easy-to-find information, whatever your immediate interest: stock or large set, special purpose die set (steel or aluminum) or forming machine types. 3 FACTORS IN DIE SET DESIGN Normal clearance in a plain bearing die set can allow misalignment, as these sketches show. When working load is applied, normal clearance becomes “redistributed”, ranging from zero to an excess. A slight lateral movement results which causes the die to wear faster in one direction. At points of zero clearance, there is danger of lubrication breakdown with resulting excessive wear and increasing misalignment. Alignment of guide posts and bushings, and the clearances provided in fitting them, contribute as much as any other factors to the efficient operation and economic life of a die. The ideal condition would involve a press fit of guide post and bushing (negative clearance), so that the resulting rigidity would assure perfect parallelism between upper and lower die set members under all working stresses. The pre-loaded ball bearing guide post and bushing offer the accuracy of a press fit, and the die set possesses at the same time an ease of operation which could otherwise be attained only by an unusually large clearance between plain bearing guide post and bushing. Further, the ball bearing assembly presents no lubrication problem such as exists when plain bearing assemblies are fitted with clearances too small for the maintenance of adequate lubrication films. Thus, there is less dependence on the press operator for successful die performance, since seizure due to the inability of the lubricant to cover all surfaces is completely eliminated. Guide post diameter and punch holder weight determine the overhang that can be tolerated before development of undue binding on plain bearing type posts and bushings. Overhang complicates punch and die alignment. A ball bearing die set maintains perfect closing action without binding, even under excessive overhang conditions. No misalignment due to clearance or overhang is found in a LEMPCO Ball Bearing Die Set. A ball bearing set offers free rolling movement vertically, and, therefore, the punch holder can be raised and lowered manually, weight permitting. 4 FACTORS IN DIE SET DESIGN When plain bearing assemblies are fitted to closer tolerances, there is an increasing tendency toward binding and galling; this difficulty affects the accuracy with which the punch enters the die. A slight cocking in any direction develops excessive die wear in the direction of displacement. The result is reduced die life overall and more frequent interruptions for regrinding. Clearance increases with wear in plain bearing assemblies. In a long run involving frequent resharpenings, the total time consumed in resetting becomes a costly nonproductive part of the job. A corollary evil stems from the higher rate of rejection due to burrs, mispunches and distortions. The ball bearing assembly helps solve the problem of alignment which results from situations where large overhangs are required. Under conditions of severe and disproportionate overhang, the “rolling press fit” of the ball bearing assembly enables the upper and lower members of the die set to maintain parallelism at the extremities. In the case of the plain bearing die set, a temporary, although troublesome, solution consists of increasing the diameters of guide posts and bushings. Slowing down the press production rate and exercising greater care to avoid mis-hits also offer additional alleviation of this problem inherent to plain bearing assemblies. When small shut height reduces the thickness of die shoes, flexing of these members may result with consequent excessive wear on the dies. The ball bearing assembly offsets to a marked degree the lack of desirable rigidity in die shoes. Ordinarily a pre-load (negative clearance) would seem conducive to binding, but because of the rolling action of the ball bearings, no such binding exists. The initial pre-load is maintained throughout the longest runs; careful tests have yielded many case histories showing that even after 25 million or more strokes a measurable pre-load still exists. The success stampers and die makers have had with LEMPCO’s ball bearing assemblies over the course of many years, together with an increasing demand for still greater parts accuracy, have resulted now in introduction of a new and even higher standard of ball bearing die set: LEMPCO’s Precision Grade. Acceptance of the anti-friction design has established LEMPCO as a prime source of supply to the stamping industry. In an effort to be of even greater service to the industry, LEMPCO makes available a line of Precision Grade Plain Bearing Die Sets. LEMPCO’s Plain Bearing Die Sets are produced with the same quality of manufacture as its Ball Bearing Die Sets. The accuracies of the LEMPCO Plain Bearing Die Sets are at least equivalent to those obtained from the best competitive materials available. LEMPCO continues to recommend earnestly its Ball Bearing Die Sets for universal application by reason of the economic factors discussed here. NEGATIVE CLEARANCE OR PRESS FIT OF BALLS BETWEEN PIN AND BUSHING BALL BEARING NORMAL CLEARANCE BETWEEN PIN AND BUSHING PLAIN BEARING NORMAL CLEARANCE IN BUSHING ALLOWS FREEDOM FOR PIN TO MOVE LATERALLY There is no lateral movement in a LEMPCO Ball Bearing Assembly because of the “rolling press-fit” action. This is not the case with the plain bearing assembly which requires clearance to function. 5 BALL & PLAIN BEARING DIE SETS –Flanged Two Post ALL STEEL • ..........Easy to assemble • ..........Guidance accuracy for holding tight tolerances • ..........Less die wear, less scrap and less chance of seizures during operation • ..........Clamping flanges for security in the press NOMINAL DIMENSIONS Ball Bearing Model Number Plain Bearing Model Number Left to Right A Front to Back B (BB) Die Holder J Punch Holder K C D E F G M N O R S T Min.

STEP-BY-STEP ASSEMBLY OF LEMPCOSHANK KITS 19 PUNCH A NEW IDEA FORDIE SET USERS A new idea for die set users – that’s LEMPCOSHANK®. Stronger than even welded shanks, it can be installed at the die maker’s convenience and need not interfere with his work. Order any size shank for any plate thickness or size – you can get it from stock. From 11/2" diameter upward, the LEMPCOSHANK® kit is comprised of a threaded stud, shank nut and two locking keys. In the 1" diameter (for small sets), the kit is a threaded shank. Both types are manufactured to bottom squarely and tighten firmly into accurately prepared sockets. LEMPCO research proves that a properly assembled LEMPCOSHANK ® – its threaded components tightened and keyed – resists displacement beyond the fatigue limit of a welded shank. There are no voids in punch holder nor interruptions in die surface. Only standard tools are needed for installation. If additional stability is desired for a 1" threaded shank, a lock can be inserted as suggested by the schematic. LEMPCOSHANK® WHY LEMPCOSHANK® OUTPERFORMS ALL OTHERS The prestressed rigidity which enables Lempcoshank® assemblies to out- perform even welded shanks starts with bottoming of the stud in its punch holder socket. The lowermost threads of both members are stressed by bottoming, as shown at left, without any material effect on the flat, ground working surface of the punch holder. Assembling the shank nut to the stud causes the nut to bottom against the machined top surface of the punch holder, creating a stress pattern (at right) in the nut and the adjacent portions of the shank stud, and in the punch holder itself. These assembly steps create stresses which are not only additive but also cumulative (illustrated at left). All members are prestressed, the critical portions being fully preconditioned. The locking keys (not shown) function in the rigidly stressed areas, providing additional stability for entire assembly.
