90 degrees,Guide Pin there will be a great flash to pitch to locate there given are not allowed to break out of the product will be error. . Now know? Why there will be a small gap?Pitch orientation, where the local contact with the materials necessary to retain the sharp corners you?Of course, need it! Useless chamfer to prevent scraping hand, handle scratch. But this place do not fall. Knife to lose the role of pitch positioning, it needs to re-patching up, and then grinding the right angle. If you think about it too sharp, you can use rasp a little scratch, but do not pour too much, oh.Feeder generally feed force and cutting edge usually only cut a narrow point, if the down angle, feeding thin, then maybe the material is directly across the mold inside pitch positioning rushed to The pitch positioning no effect.
Generally like a big point of the modulus of continuity are used in dual-purpose pin pitch positioning into the block,Punch Pin that is, pitch positioning there is a special one into the block, installed rely knife, cutting edge there, but relatively small in the mold, thin materials, does not apply to such a structure. Think about why?General in the mold is relatively small, and relatively thin material, the plate instead of dual-use sales, because the material is relatively thin, using a plate feeding relatively well to send some words of dual-use sales more trouble. This situation is typical with plate + pitch positioning into the block, or simply do not pitch positioning into the block, has a plate, why use the pitch orientation into the block.? Design is not to eat dog feces, rotten mold design such Ha ha ha.
If you design a mold plate + pitch positioning into the block form fitter master when in group mode,Guide Bushing will be to the above phrase, like curse you. Why am I so clearly? Because there is such a stupid design to design such a bad mold, then the fitter of our colleagues is so scolding him, behind the joke. . Hee hee.Direct use of the platen how pitch positions? Is this. Material width is 10 mm, trimming and cut off two millimeters, the distance between the first pair of plate can be designed for 10 mm (of course, to put the gap, do not be silly!), Rely on the knife here trimming cut off two millimeters, then the second pair of plate between the distance (that is, trimming) you can design to 8 mm, Did not we just could pitch positioning.
Repair stamping die needs will be the technology and processing equipment used ? To talk about stamping dies are made out of it before I wrote the article a "stamping die development process",dowel pin not to ramble on here, simple to talk about.Various parts of the stamping die must first undergo these procedures:First is expected to open, the material out how to further processing it. A material, means roughing. Generally a template must first be subjected to planer probably planed, and then through a large water mill (grinder, also known as Grinder) coarse grinding, roughing, leaving a certain margin (usually leaving 50 margin, the precision of plus or minus ten can), and then need to be heat-treated to take the heat treatment, heat treatment is completed, after the finishing of large grinding machine, this time accuracy requires a little higher, for example, the template thickness is 25.00mm, so the accuracy requirements must be plus or minus 0.01mm or less.
Look at the role of the template, the general difference between one to two did not matter much, as long as the mold marks on the product does not like to play out.Over the grinding machine,Linear bearings sent to put the thread hole, and then the line cut, and then milling, CNC and other.If small parts, is this: according to part size, saws, a saw or a milling machine milling, grinder grinding after rough opening, cut off the excess piece of cutting, and made almost the same situation or go to the wire cutting cut, or go to the CNC (also a high-speed milling machine) processing, the need to discharge and release point. After the expiry of the quality assurance measurements.
