Battery pinch Progressive Die Design

Consequently prevent channeling strip Received date: 1998, on March 5 3.1 feed positioning the mold 4 Small guide 12 and fixed plate for the H7/n74 No. 8 Total 210j0 Figure 3 with the expansion plan of the transition, with the concave template, stripper plate are H7/h6 the gap with the work of the mold to ensure the accuracy and convenience of the upper and lower die assembly. Step away from the rough location of air from the small automatic feeder is complete, the feeder high accuracy, and coordination with the lead was nailed with, easy to use. Step away from the fine positioning by the nail guide is completed. Guide is an effective part of the nail above the stripper plate 0.8mm, with double-sided strip hole clearance is 0.02mill. 3.2 The three main design template in addition to forming part of the template with concave inserts, the other is integral to resize. Blade height 3nml, for materials to expand the hole side 0.4ram, to reduce the expansion force. Fixed plate and stripper plate is used quenched and tempered steel 45 to 30 ± 2HRC. A conducting mock orange 1 4 modules of its station. Plug 2. Block 3 under the lower die plate 4. Au template 5. Carrying materials nail 6. Stripper plate 7.

Ejector block No8 total discharge board in 2105 bound for processing,tory burch uk, assembly and punch grinding blade VI. It is worth noting: the depth of discharge plate countersunk head screws must be highly consistent material lift,mulberry københavn, or strip in the punching process can not be squeezed or pressed, of stamping forming. Bending punch mounted on the fixed board, the purpose of securing the guide strip is, after the compression forming three template-type holes are used Fujitsu's P-type cutting machine processing, accuracy up to ± 0.01mm3.3 Design of circular punch punch by steps fixed. Non-working part of the size increase as the straight-shaped punch, line cutting, with a cylindrical pin hangs fixed bending punch is also used a fixed level, because of unilateral force to prevent the slip, pieces of l8, 19 working part designed to be stepped so that backward bending of the pilot to ensure dimensional accuracy. 3.4 The design bending forming inserts inserts with a fixed level,Mulberry tasker, with push rod holes. For stripping, forming size according to theoretical design. Although the material of 2crl3 spring angle more, but based on years of experience and many of the measures taken in the mold after the rebound did not find much value. In fact, in the bending process step 6, the end or even 0-8. Negative rebound, which is 5. Becomes 5.8. . 4 Note (1) greater height of the workpiece bending, lifting the state should be higher than expected nail free surface of a certain size of the die, or affect the feeding. In addition, the lift should be close to the expected location of a conducting screw nails, easy to discharge. (2) The mold shape of the larger, test mode, you must put an end at the pieces the same thickness of the gasket, the mold to maintain balance. (3) To improve the die strength, 7-step trimming work will be expected when the waste is not cut off,ed hardy kleider, so the waste strip rolled with a roller frame for recovery, centralized treatment. 5 Conclusion of the mold is only a test mode, in addition to the negative end of the rebound into a 5-8 tick size. , The other dimensions are in line with requirements. Since 5.8. End the use of parts. By authorized users, without modification inserts. This has produced 570,000 die, die use of safe, reliable, part size and stability. , Lf &,,{] branches of a tree. ATM PCB punching die Di Teachers Zhejiang (Ningbo, Zhejiang 315101) 1 PCB Analysis of Blanking Process of new electronic products as the continuous development of varieties and specifications as printed circuit boards is also increasing. But no matter, or printed in large, small PCB, they all have a common characteristic, that is, the majority of phenolic substrates used paper-based copper clad laminates (with a few paper substrate for the epoxy, epoxy cloth panels), pass more, and the hole (15ram below) based. Figure 1 shows the electronic energy of the PCB 8 H component Received: January 8, 1998 made three Zhu - Yao Shen limonene ink √ Autumn cover foil pattern, Figure 2 shows the punching process map. I. 1 punching holes in the PCB assembly is connected to pieces of eight energy-saving, 1.5mm below the hole up to 544, and to 4, o. 8ram hole for the majority. The relative aperture d / t (1.3 poor punching holes, mold manufacturing difficulties, the use of small punch easily broken,ed hardy shop, with the materials used for the primary phenolic paper plate, punching one of the resin produced when sticky adhesive to soften and easy punch into the die parts can not completely rely on white weight under
