How To Effectively Improve The Quality Of Sheet Metal Processing

With the increasing number of domestic Sheet Metal Processing manufacturers, the competition in sheet metal processing has reached an unprecedented level; therefore, improving the quality of sheet metal processing has become an inevitable choice for the majority of sheet metal processing companies to survive and grow! So, as a sheet metal processing enterprise, how can we effectively improve the quality of sheet metal processing? We believes that we can start from the following aspects:

1. Strictly abide by the scientific and effective sheet metal processing process.
Sheet metal processing is a very organized and process-oriented processing technology; in order to do a good job in sheet metal processing, it is an indispensable choice to strictly abide by the scientific and effective sheet metal processing process; scientific and effective sheet metal processing process In order to: clarify the production outline and determine the production type - analyze the part drawing and product assembly drawing, and also conduct technical analysis on the parts - select the blank and draw up the technical route - - analyze each Determine the machining allowance of the process, and calculate the process size and tolerance--the equipment, tools, fixtures, measuring tools, and some auxiliary tools used in a process must be determined--determine the cutting amount And the working hours quota, as well as the technical requirements and inspection methods of each main process - fill in the technical documents and make corresponding records.

2. Do a good job in various mechanical operations in the sheet metal processing process.
In sheet metal processing, doing various mechanical operations effectively can effectively control various processing qualities; the common mechanical operations that must be done well are as follows:
a. Welding in sheet metal processing generally includes hydrogen arc welding, spot welding, manual arc welding, and carbon dioxide-shielded welding. When spot welding is made, the welding position must be considered.
b. For the pressure riveting of the workpiece, the height of the stud and the pressure of the press must be taken into consideration. In addition, the surface of the stud and the workpiece should be flush to avoid scrapping the workpiece and making it unusable.
c. After the sheet metal is processed, it is necessary to carry out a visual inspection, including dimensions, etc. If there is any problem, it should be repaired or scrapped directly, so as to ensure the processing quality.

3. Eliminate various factors that may affect the quality of sheet metal.
In the process of sheet metal processing, generally speaking, the factors that will affect the quality of sheet metal processing include the following aspects:
a. Physical and mechanical properties: mainly in terms of the metallographic structure change of the surface material and the surface residual stress. Generally speaking, the stronger the plasticity of the workpiece material, the more obvious the cold and hard phenomenon.
b. The use performance of machinery and equipment is mainly the wear resistance, corrosion resistance, and fatigue strength of the machinery and equipment. The better the wear resistance and corrosion resistance, the better the deformation and corrosion can be prevented, thereby preventing severe damage. wear and tear.
For the above factors, we can adopt the following solutions:
a. The cutting fluid should be selected reasonably, which can reduce the friction coefficient and cutting temperature, thereby reducing the wear of the tool.
b. The process specification should be formulated scientifically and reasonably to ensure the appearance and quality of the workpiece. Therefore, the positioning should be accurate and the process flow should be as short as possible.

4. Appropriate use of precision machining.
First of all, in order to achieve precision machining, there are many aspects involved, such as the machining accuracy of processing equipment, here mainly refers to lathes, etc., and the technical level of operators, in addition to other factors, But for the first two, they are essential, and are relatively demanding.
Secondly, for precision machining, not all raw materials can be used. It also has some requirements. For example, in terms of hardness, although it is required that the hardness of the material should not be too low, it should not be too high and cannot exceed the requirements of the machine equipment. hardness, otherwise it will be damaged.
Sheet metal processing is not something unfathomable; if in the process of sheet metal processing, strictly abide by the above four items, you will be able to process high-quality Sheet Metal Parts!
