Improving the quality of Sheet Metal Processing is a way for sheet metal processing manufacturers to improve their business resources. So how should we improve the quality of sheet metal processing? The sheet metal shell processing editor will analyze it for you.

How can the quality of sheet metal processing be improved?

First, do a good job in sheet metal processing.

In sheet metal processing, there are generally four methods for blanking, namely:

Cutting machine: It is to use a cutting machine to cut out the external dimensions, and then punch the machine in combination with the die for punching, corner cutting, etc., and then complete the cutting.

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

Punch blanking: It is the use of a punch to form flat parts and other structures, which can be completed in one step or in steps.

Numerical control blanking: It is commonly used in ZUI, which is to realize numerical control through programming, and then can carry out the punching of the structure and shape, and then complete the blanking.

What are the qualification requirements for sheet metal processing personnel? What are the specific goals? If it is a junior sheet metal operator, it is required to be able to understand the drawings, as well as the simple operation of the equipment, without too deep and complicated. And intermediate, it is required to be able to understand more complex drawings and have certain physical knowledge. Therefore, different goals have different requirements.

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

During the processing of sheet metal parts, some problems sometimes occur, such as laser cutting, so we should have a better understanding of it. Then let‘s briefly discuss and analyze it.

1. Deformation. The main reason is that when machining small holes, explosive perforations are not used, but pulse perforations are used, which will affect the processing quality.

2. Burr. The main reasons are: the up and down position of the laser focus is incorrect, or the output power is not good, or the cutting speed is not good, the gas purity is not good, etc., so it needs to be analyzed in detail.

3. It is not completely cut when cutting. The line speed of laser cutting is too fast, or the selection of the laser head nozzle does not match the thickness of the processing plate, which will cause this problem, and then affect the processing quality.

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

In the bending of sheet metal materials, the tools and tool slots to be used for bending should be determined according to the size requirements of the drawings and the thickness of the materials, etc., to prevent the product and the tool from colliding and then causing deformation. In addition, the order of bending is also very important, generally first inside and then outside, first small and then large, and first special and then general. If the workpiece needs to press the dead edge, then the leveling die should be used.

The pressure riveting of the workpiece should take into account the height of the stud, as well as the pressure of the press, etc. In addition, the stud and the surface of the workpiece should be flush to avoid making the workpiece obsolete and unusable.

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 should be taken into account.

In sheet metal processing, the appearance treatment should be selected according to the actual situation. If it is cold plate processing, then electroplating treatment is generally carried out first, then phosphating treatment, and then spraying after ZUI. Its spraying is divided into craftsmanship and initiative.

In addition, after the sheet metal is processed, it is necessary to check the appearance, including the scale, etc. If there is any problem, it should be repaired or directly scrapped to ensure the quality of the processing.

Fourth, improve the technical level of sheet metal processing masters.

1. On the surface of the parts, the oxide skin should be removed first, and there should be no defects or damage before machining.

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

3. If there are no shape requirements for public service, it should comply with the requirements of the rules in GB1184-80, and the allowable error of its length should generally be within the range of 0.5mm.

4. After the gear is installed, its tooth surface backlash should comply with the requirements of GB10095 and GB11365.

5. Before installing the parts, some necessary inspections and cleaning must be carried out to avoid bringing in foreign objects. In addition, check the mating clearance, etc.
