Guizhou progressive die progressive die manufacturing plant / Chengdu stamping process stamping 15025387227 [Goldsmith] 1, to reasonably conclude work steps: Step Number Chongqing workers die stamping die successive differentiation equal to the sum of a single step, such as punching - Workers successive steps blanking die, usually equal to punching and blanking the sum of two single step. But in order to add strength and ease of die punch apparatus, sometimes end in several steps according to the number of the hole. Guidelines concluded its work steps, mainly die without affecting the strength of the guidelines, the number of steps in its work, the better choice, fewer work steps, the accumulated error smaller scale precision workpiece is being punched higher. 2, in the absence of a circular hole in the workpiece in order to improve the accuracy of the feed pitches, the first step in order to plan the die orifice in technology to make this technology as the guide hole being positioned, progressive stamping accuracy. But as today's mold plan, it for some precision parts stamping has been gradually or all selected frame style guide strip. This will help ensure accuracy messy workpiece. 3, demand the same high precision reference scale is not the same hole, without prejudice to the die strength of the case, it should be organized in the same step shape. 4, high precision requirements step scale, it should be organized in a final step, but the demand is not too high precision step, the best organization in the previous process step, which is due to step more forward, its accumulation error increases. 5, in a series of multi-step mold, Taiwan punching, cutting, grooving, zigzag, forming, cutting and so on. 6, red is not the same shape and dimension of the porous process, try not to put a large hole and the hole at the same time on the same step, so that when the repair mode to ensure the accuracy of pitch. 7, when planning, forming and blanking end if on the same die, the forming punch and punching punch should leave fixed, surface not fixed in the same mounting plate. Try to shaping punch off the plate fixed to the top. Behind the installation of the backplane. 8, in the planning, will make each step has been formed, some are not damaged, so that the strip remains in the same feed line. 9, on the number of process steps and with more tortuous many mold step, the die edge should try to use the block structure, the replacement can be completed quickly and grinding. 10. A method for fixing the punch, at the completion of a series of stamping, to use a fixed method to hang desk and anti-compacts to ensure that the press does not matter in a series of episodes of fall and damage Chongqing punch metal mold. Keep in mind! 11, in the case of mold construction strength and orientation promised. Multi-stage mold to try to use material from the floating guide pin.
