It is suitable for parts with thick blank and large fillet transition, and it is not easy to wrinkle. How to calculate the die cost of metal stamping parts?

With the development of society, the stamping products of Xiamen aluminum alloy die casting parts have been widely used in various industries, and the molds used to process stamping parts are also various. Each mold has its unique function and characteristics. Today, we want to talk about the continuous die. The design of continuous die requires that the parts should have sufficient strength, the selection of materials should not be wrong, and the operation, adjustment and safety should be considered in the design Assembly, repair, handling and other aspects to ensure the safety of operators in the work; to determine the number of work steps reasonably, the number of work steps of the continuous die of stamping parts is equal to the sum of the single process of decomposition, such as punching and blanking. In order to increase the strength of the stamping die and facilitate the installation of the punch, sometimes it can be completed in several steps according to the number of inner holes Under the principle of not affecting the strength of the die, the less the steps, the better; the smaller the number of steps and the smaller the cumulative error, the higher the accuracy of the punched parts; in the continuous die of multi-step stamping parts, the operations are usually carried out in accordance with the procedures of punching, cutting, grooving, bending, forming and cutting; in the design, the formed parts of each step must not be damaged If the forming and blanking are completed on the same stamping die, the forming punch and blanking punch should be fixed separately, not on the same fixed plate. The punch should be fixed on the stripper as far as possible, and the back plate should be added at the back. For the fixation mode of the punch, the hanging table and counter pressing block should be used to fix the punch How to arrange the processing sequence of metal stamping parts?.

Xiamen electronic components processing, of course, don't forget to let the manufacturer processing fingerprint.



Metal processing customization. Therefore, when the number of stamping parts is small, the simple die is usually used. On the contrary, the die structure with long service life should be used. According to the dimensional accuracy requirements of stamping parts, the precision class of stamping die should be determined. When the dimensional accuracy and cross-section quality of stamping parts are required to be high, the fine stamping die structure should be adopted. For the stamping parts with general accuracy requirements, the ordinary die can be used. The precision of stamping parts produced by compound die is higher than that of progressive die, and that of progressive die is higher than that of simple die. The reason is that the accumulative error is large when using simple die to process multi process stamping parts, so the accuracy of stamping parts is low. When the progressive die is stamping, it is inevitable to have feeding and positioning errors, but the guide pin can be used to guide, and the accuracy is also high. Compound die is to punch out the workpiece at the same position of the die, there is no positioning error, so its blanking accuracy is very high. Therefore, for stamping parts with high accuracy requirements, composite die is mostly considered. Select the type of die according to the equipment capacity. For example, in the case of double action deep drawing press, the structure of double acting die is relatively simple. Some connectors in electronic products need not only multiple sets of dies but also low efficiency when they are produced on general press. If they are produced on universal bending automata, the die structure is simple and the production efficiency is high. According to the size and shape complexity of stamping parts, the die structure is selected. Generally, for large stamping parts, in order to facilitate the manufacturing of dies and simplify the dies, the die structure is selected Simple die is used for structure; compound die or progressive die is commonly used for small stamping parts with complex shape. The progressive die with continuous drawing should be used for the cylindrical parts with large output and small external dimensions, such as semiconductor transistor shell; the mold type should be selected according to the mold manufacturing capacity and economy; when the high-level die can not be manufactured, the feasible and relatively simple die structure should be designed as far as possible. But under the condition of considerable equipment and technical strength.



What are the reasons for the unilateral burr of the metal stamping parts in Xiamen turn milling compound processing factory? The main reasons for the single side burr of the metal stamping parts are as follows: 1) the die assembly error, such as the punch and the fixed plate are not vertical or loose due to wear, or the positioning pin is loose, which can not ensure the correct fixed position of the male and female die. 2) The guidance accuracy is poor. The center lines of the upper and lower dies do not coincide with each other due to the excessive fit clearance of the die guide parts, which affects the uniformity of the stamping gap. 3) Installation error. The position of the upper and lower die is not allowed during the installation of the unguided die, resulting in the uneven gap. If the surface of the upper die plate or bottom plate is not clean or the upper die screw is not properly tightened, the working part will be inclined. 4) The die deforms when it works. For example, the leakage hole of punching mattress board is too large, the lower template of die is too thin, and the rigidity of female die is not enough. 5) The gap between the guide rail of punch press is too large, the parallelism between the bottom surface of slide block and the working table is not good, or the sliding direction of the slide block is not vertical to the working table. 6) When the maximum resistance of the workpiece is more than 80% of the nominal pressure of the punch press, it is easy to deform the "C" shape bed of the open type punch, so that the center lines of the upper and lower dies do not coincide.
