10. Assembly The so-called assembly is to assemble multiple parts or components in a certain way to make them into a complete material. One of the things to pay attention to is the maintenance of materials and parts, which should not be scratched or bruised Assembly is the last step for the completion of a material. If the material cannot be used due to scratches, it needs to be reworked and redone, which will waste a lot of processing time and increase the cost of the material. Therefore, pay special attention to the maintenance of the material
3、 Sheet metal processing technology There are always some problems in sheet metal processing. You need to optimize its process to make it a good product or achieve a specific purpose. Here is a brief introduction to some process problems that we often need to pay attention to in sheet metal processing
1. For door panels, generally, the processing method of wrapping the long side with the short side is used, and then the process hole is opened at the corresponding corner. The size of the process hole is generally determined by the thickness of the plate. When the plate thickness increases, the size of the process hole should also increase accordingly, otherwise edges and corners will be generated during bending
2. For weldments, generally the fixture, hole or convex hull is used for positioning welding, which can reduce the wasted working hours during positioning, ensure the size, improve the work efficiency, and reduce the cost. For welding that is relatively difficult to position, convex hull or hole positioning is generally used
3. Electroplated parts, because the electroplating solution has a corrosive effect on the materials and parts, it is generally necessary to add process holes at the corners of the electroplating parts to facilitate the timely discharge of the electroplating solution to ensure the quality
4. For a large sheet metal part, when the data will be wasted to some extent, we should consider to fold it into several sub parts for separate processing, and then weld them together, which not only ensures the quality, but also reduces the waste of data and saves costs
Introduction to sheet metal foundation (II)
1、 Materials used for sheet metal
Common data include: cold rolled sheet SPCC, electrolytic plate SECC, ordinary aluminum plate and aluminum alloy plate AL3003-H14, AL5052-H32, stainless steel plate, checkered plate SGEC. Recently developed new data: aluminized zinc steel plate
2、 Sheet metal processing method
1. Blanking method Blanking is to cut thick materials into bad materials as required. There are many methods for sheet metal blanking. According to the type and working principle of the machine tool, it can be divided into shearing, milling, punching, oxygen cutting and laser cutting. Our company mainly uses shearing, punching and laser cutting (LASER)
1.1 Shearing is mainly used to cut the plates with straight edges. It is required to ensure the straightness and parallelism of the cutting surface and minimize the distortion of the plates
1.2 Blanking shall be stopped by CNC punch or ordinary punch and blanking die
1.3 Laser cutting applies laser cutting equipment to stop continuous cutting of plates, which is characterized by high efficiency and high precision
2. Manual forming
With the constant technological progress of consumption, most of the forming processes are completed on machines. Manual methods are often used as supplementary processing or finishing work. However, in the case of single piece consumption, or some parts with complex shapes, manual operation and processing are still indispensable. Manual forming is mainly accomplished by using some simple tire shapes, templates and various kinds of jigs and fixtures Manual forming mainly adopts the following methods: bending, edge setting, edge closing, edge pulling, arch bending, curling and seam correction
3. Tool and die forming
Tooling and die forming is the application of punch, folding machine and other machines and a variety of molds to complete the forming of sheet metal It can be divided into: bending, drawing, partial forming and flanging, necking, necking, flaring and bulging, forming, stretch bending forming, spinning forming and leveling. Our company mainly adopts bending (bending), leveling or forming processes
Bending is one of the main methods of sheet metal processing
