Stamping process design analysis and determined

Combined with the content of the above design, stamping process design is as follows, 1, punching type from intuitive to see the parts stamping type for blanking and drawing. The requirements of the stamping precision is not high do not need large deformation, so easy to meet, don't need to add additional stamping process. According to the paper analysis the shape of the stamping characteristics to that type of punch for blanking and drawing. 2, the number of times a number of stamping process in stamping process is divided into two types: the same process and different processes. For blanking pieces without the same working procedure, for tensile) is likely to have the same process if he is a single process model, the stamping process for two times, if it is a progressive die or die, is also for a number of stamping process. 2, there are three kinds of stamping process program stamping process program is as follows: plan a: blanking - — Stretch - — Trimming scheme 2: drawing and blanking compound - — Trimming plan 3: blanking progressive stamping and stretching - — Trimming first analysis scheme one: blanking - — Stretch - — Trimming advantages: 1) The result of the mould is simple, long life, low cost of manufacture. 2) Rushed out of the parts of high precision. Disadvantages: 1) Procedure, need more mold, equipment, staff also many, therefore increases the cost. 2) The production efficiency is low. Suitable for sheet small batch production. 3) In the process of handling easy deformation. Affect the accuracy of stamping parts. 4) Safety factor is not high. So are not suitable for use solution 2: blanking and drawing compound - — Trimming knowable by the solution process route, the number of stamping parts in the process of stamping once, at the same time also can know already in the stamping process program stamping combination method for the composite process of stamping advantages: 1) Process more concentrated, compact structure, need less number of mold, occupied less equipment, but also reduce staff, cover an area of an area small, 2) High production efficiency. Suitable for mass production. 3) Rushed out of the high precision parts, stamping parts are flat and level. 4) The service life of mould is higher shortcomings: 1) Mold structure is complex, manufacturing, maintenance is not convenient. 2) The quality of stamping parts relative to the 'plan a' relatively lower. 3) Mold structure is complex, so also the requirement of equipment is also higher. Solution 3: blanking progressive stamping and stretching - — Cutting through the solution of three process routes, the number of stamping parts in the process of stamping once, at the same time also can know the stamping in the process of combination way for progressive stamping process. Advantages: 1) Easy to implement mechanization, so security is relative to the front of the several solutions to some high 2) Process, the mould number less, less equipment, also reduce the staff. 3) High efficiency disadvantages: 1) Design is more complex, the mould structure is complex, manufacturing difficulty, maintenance is not convenient, service life is also low, the mold size is larger. 2) The quality of stamping parts are better than the front several solutions are lower. 3) Progressive stamping process requirements of equipment requirement is high, so also increased the cost. 4) Stretch is blanking in drawing, because the first blanking, 柸 material will not automatically fall into the stretch of the hole, need to increase the other devices, cause mould more trouble. 5) Waste of materials. 3. Optimization of stamping process program according to the drawings provided by the user, and analyze the drawings, the stamping parts quality is not high, the highest level of precision IT14, for mass production, but also to the life of mould and relative to the higher, and also have to benefit for the convenience of the operators, the production efficiency is high. So through the appeals process comprehensive analysis and comparison of three kinds of schemes, choosing the finalized one option two, namely tensile and blanking die.
