F80 Mounting example: with spacer sleeve Description: The preloaded combination spring- and spacer unit combines the functions of providing the spring force and of spacing the stripper in one constructional element, whilst conventional designs employed two. The resulting advantages therefore consist of space savings and reduced machining cost with regard to the various die members. The execution with spacer sleeve makes it possible to exchange the whole unit by simply removing the top clamping plate. Removal of the compensation disc gives unimpeded access to the punches – for the purpose of sharpening/grinding. Note: Helical compression springs must be ordered separately, see at the beginning of chapter F. After fitting, the resilient collar pins are ground to the same length. Attention: Regrinding of stamp in mm = regrinding of spacer. This means that the spring force and displacement always remain exactly the same. Match the blind hole drill depth h3 and/or spacer height so that the screw is released by about 0.1 mm. 244.xx.3.xxx.10 Spring- and spacer unit for compression spring, low installation space, without spacer sleeve 244.xx.3.xxx.11 Spring- and spacer unit for compression spring, low installation space, with spacer sleeve Spring ø d1 3 s h* d2 d3 d4 d5 d6 Dh s1 s2 h1 h2 20 10 3 1,8 M6 18 25 25 31 20 3 4 5 36 25 12 3 1,8 M8 18 32 25 38 25 3 4 10 36 32 16 3 2,5 M10 30 38 38 44 32 4 5 16 40 40 20 3 3,5 M12 30 47 38 54 40 4 5 18 40 * h = Spacer tube length 244.9.
