To improve the quality of sheet metal processing, you can start from the following aspects

First, do the blanking work of sheet metal processing.

The blanking methods in sheet metal processing generally have four primary methods,

Blanking of shearing machine: It is to use shearing machine to cut out the shape dimensions, and then punching and corner forming with punching machine combined with die, etc., and then finish the blanking.

Laser cutting: It is the method of laser cutting to cut out the desired structural shape.

Punch blanking: It is the use of a punching machine to punch the structure of flat parts, etc., which can be completed in one step or completed in steps.

Numerical control blanking: It is the most commonly used, which is to realize the numerical control through the preparation of the program, and then the structure and shape can be punched, and then the blanking is completed.

What qualification requirements should sheet metal processing personnel have? What objective is this score in detail? If it is a junior sheet metal operator, it is required to be able to understand the drawings and the simple operation of the equipment, without being too deep and complicated. The intermediate level requires that you can read more complicated drawings and have certain physical knowledge. Therefore, different goals require different requirements.

Second, do a good job of cutting the sheet metal processing.

Sometimes some problems occur in the processing of sheet metal parts, for example, laser cutting, so we should understand it. Then let's briefly discuss and analyze.

1. Deformation. First of all, it is because the explosion perforation is not used when processing small holes, but the pulse perforation is used, which will affect the processing quality.

2. Glitch. The first reason is: the position of the laser focus is not correct, or the output power is not good, or the cutting speed is not good, the gas purity is not good, etc., so a detailed analysis is required.

3. Not completely cut through when cutting. The line speed of laser cutting is too fast, or the selection of the nozzle of the laser head does not match the thickness of the processing plate. This problem will occur, and then the processing quality will be affected.

Third, do a good job in sheet metal processing center.

Bending of sheet metal materials should be based on the requirements of the drawing scale and the thickness of the materials to determine the tools and sipes to be used for bending, to prevent the product from colliding with the tools and then causing deformation. In addition, the order of bending is also very important, generally from inside to outside, then from small to large, and from special to general. If the workpiece is to be pressed to the dead, it should be applied to the leveling die.

Riveting of the work piece should take into account the height of the stud and the pressure of the press. In addition, the appearance of the stud and the work piece should be flush to avoid making the work piece invalid and unable to use.

Welding in sheet metal processing generally includes hydrogen arc welding, spot welding, technical arc welding and carbon dioxide maintenance welding. When making spot welding, the welding position must be considered.

For sheet metal processing, surface treatment is to be selected according to the actual situation. If it is cold plate processing, then generally electroplating treatment, then phosphating treatment, and then spraying. Its spraying is divided into workmanship and initiative.

In addition, after the sheet metal processing is completed, it is necessary to check the appearance, including dimensions, etc., if there is a problem, it should be repaired, or directly scrapped, so as to ensure the processing quality.

4. Improve the technical level of the masters of sheet metal processing.

Sheet metal processing, the detailed technical requirements are:

1. The surface of the parts should be removed after the scale is removed, and only after checking that there are no defects or damages before machining.

2. If high-frequency quenching is to be performed, the tempering temperature should be within the range of regular temperature requirements, and high-temperature aging treatment is required.

3. If there is no shape public service requirement, then it should meet the requirements of the rules in GB1184-80, and the length tolerance is generally within ± 0.5mm.

4. After the gear is installed, the backlash of the tooth surface should meet the requirements of the rules in GB10095 and GB11365.

5. Before installing the parts, you must carry out some necessary inspection and cleaning to avoid foreign objects. In addition, it is necessary to check the fit clearance.
