How to optimize the design of sheet metal parts

1 Blanking link

First of all, as far as the blanking link is concerned, under normal circumstances, blanking refers to the separation of the sheet metal materials through the punching of the mold, thereby achieving the separation of the sheet metal. This link is usually applied to the relative processing shape. Relatively simple parts processing links, so as to achieve a higher degree of accuracy in processing shapes, while reducing material waste to a greater extent.

In this link, the shape of the blanking sheet metal parts should be controlled first. In the corner areas of the outer and inner holes of the blanking and cutting, an arc should be set to overshoot the corners to avoid sharp angles and reduce the risk of follow-up. The problem of mold cracking caused by improper heat treatment process affects the subsequent sheet metal construction; then, the punching and its small value should be optimized. Under normal circumstances, when punching sheet metal parts, if the punching size of the sheet metal parts is small, it will greatly reduce the load on the punching machine, but if it is too small, it will easily cause the mold to be carried. The pressure data is suddenly even worse, which in turn affects the quality of the actual mold. For example, in this link, the punching of the sheet metal parts should be set according to the different load targets of the sheet metal parts. In the basic state, the length of the hole diameter should be more than twice the hole spacing and greater than 3.00 mm. Later, the cantilever and groove setting on the blanking parts should be avoided in the actual process application link to be too narrow or too long, so as to improve the strength of the die edge while controlling the cantilever notch width to be greater than two hundred sheet metal thickness.

2 Bending link

The bending link usually refers to the prevention and treatment of sheet metal materials on the bending equipment, and the elastic deformation of the sheet metal materials occurs through the pressure of the upper mold or the lower mold, and plasticity occurs according to the actual design plan after the elastic deformation occurs. The process of deformation.

In the application process of this link, different parts should be selected to set the size according to the actual design requirements, and the actual bending operation should be determined according to the thickness of the sheet metal material. According to the actual bending experience, local abnormal deformation is prone to occur in the bending link, which will affect the appearance quality and actual application of the sheet metal parts. Therefore, in the actual operation link, it is necessary to carry out the process for the bending link. The optimization should be performed by the operator according to the actual situation in advance to avoid the problem of subsequent deformation. At the same time, when parts need to perform multiple bending operations, a comprehensive estimate should be made during all the bending operations to avoid the prior bending operations from affecting the subsequent bending processes, so as to achieve the expected sheet metal Gold design goals.

3 Pressure riveting link

The riveting process of sheet metal parts means that the sheet metal materials are deformed by pressure to couple them together. This process is usually used in screw riveting, bolt riveting, etc. As far as the riveting operation is concerned, the nut is usually round and has an embossed gear and wire notch. Therefore, the riveting process for sheet metal parts not only optimizes the quality of the original nut production process, but also avoids the welding work.

If you want to get a better design plan, first of all, you can choose different specifications of molds according to the height of different pressed bolts in the actual riveting process, and adjust the pressure release of the riveting device to ensure the quality of nut pressing while avoiding There is a problem of scrap parts. Secondly, in the setting of the pressure riveting structure, the suitable sheet metal size can be selected, so as to ensure the pressure riveting result while avoiding the sheet metal parts from coming out of the pressing link.

4 Welding link

The welding link is one of the important ways to connect the various parts of the structure in the cold working link of the entire sheet metal processing process. Therefore, this link is usually placed in the background of high temperature for operation. At present, most of the common welding methods are carried out by argon arc welding, contact spot welding and other methods.

Therefore, in the actual welding process, different welding methods should be selected according to the properties of different sheet metal parts, to a large extent, to ensure the reduction of welding deformation and improve the actual efficiency of welding. For example, in the actual welding process, first of all, it is necessary to determine the sufficient welding control left, and secondly, the length of the welding part needs to be controlled more accurately to avoid sheet metal misshapen while optimizing the load of the welding point.
