How To Optimize Sheet Metal Design?
- Dec 12, 2018 -

With the deepening of social construction in China, sheet metal parts have been gradually applied in people's lives.

In general, sheet metal processing is a process of cold processing with sheet metals to obtain sheet metal fittings that meet the needs of the application.

In general, sheet metal parts have a more obvious strength, weight and cost advantages, at the same time compared to the traditional components have a better point performance, as so far, sheet metal parts have been gradually used in China's electronics, communications and other high-tech fields, At the same time, people also gradually put forward higher requirements for the quality and function of sheet metal parts, thus, for the original sheet metal processing process for appropriate optimization, it has become the focus of sheet metal processing personnel research.

According to the actual research, this paper thinks that the optimization of the processing technology should be carried out one by one from the application of the four basic cold processing links in sheet metal processing.

1 Punching,

First of all, as far as the punching concerned, usually punching refers to the separation of sheet metal through the die, which in turn leads to the separation of sheet metal materials, which is usually used in the processing of parts with relatively simple machining shapes.

In order to achieve a high degree of precision in the processing shape at the same time to minimize the waste of materials. In this link, first of all, should be aimed at punching sheet metal parts of the shape of the control, can be in the punching cutting outside and the corner area of the inner hole, should set the arc of the way to do the rotation of the corner, to avoid sharp angle. The punching and its minimum value should be optimized. Usually, in the punching of sheet metal parts, if the punching sheet metal parts of the punch size will greatly reduce the load cast of the hedging bed, but if too small, it is easy to cause the mold bearing pressure of the data suddenly more, and then affect the actual mold quality situation. For example, in this link should be based on different sheet metal load targets on the sheet metal punching settings, the basic state should ensure that the length of the aperture above two times the hole spacing, and greater than 3.00 mm.

Finally, for the cantilever and groove settings on the punching parts should be in the actual process application link to avoid too narrow or too long, so as to enhance the strength of the mold blade at the same time to control the cantilever incision width should be greater than 200 of the sheet metal thickness.

2 Bending,

Bending link is usually referred to as the control of sheet metal materials in bending equipment, through the pressure of the upper or lower die so that it occurs elastic deformation of sheet metal materials, and in the event of elastic deformation in accordance with the actual design of the process of plasticity deformation. In the application process of this link, according to the actual design needs, choose different parts to set the size, and according to the thickness of sheet metal raw materials to determine the actual operation of bending. According to the actual bending experience, in the bending link is most likely to appear local abnormal deformation, and then affect the appearance of sheet metal parts of the quality and practical application, so, in the actual operation of the process, the desire to optimize the bending link should be made by the operator according to the actual situation of the advance incision, so as to avoid the problem of subsequent deformation. At the same time, when the parts need to carry out a number of bending operation, should be carried out in all the bending operation link to carry out a comprehensive estimate, to avoid the first bending operation affecting the subsequent bending process, so as to achieve the expected sheet metal design goals.
