The characteristics of sheet metal are very light, high compressive strength, electrical conductivity (can be used for magnetic shielding materials), low cost, good scale burning characteristics, etc., in the electrical and electronic, communications, automotive industry, medical machinery and other industries have been very widely used, such as in the main chassis, mobile phones, MP3, speakers, sheet metal is an indispensable composition.

Problems and Solutions in 1. Sheet Metal Processing

1. In many fields of production and manufacturing, sheet metal processing must be carried out. Each task contains a lot of contents, such as cold stamping die and sheet metal bending forming of raw materials. During the whole process of such processing and operation procedures, the staff should pay attention to whether the basic parameters are accurate and whether the application method meets the standard requirements, at present, the workplace has also attached great importance to the processing quality of raw materials. Therefore, in the whole process of the processing operation, attention should be paid to the development trend of professional methods and skills, which is in line with the development trend regulations in the field of production and manufacturing. The following is a simple and detailed explanation for the difficult problems in the processing work.

2. When processing raw materials for sheet metal, although for the daily work of a process, attention should be paid to greatly reducing energy consumption and reducing the supply of raw materials will not do great harm to the recovery of costs. Therefore, for long-term production, if reducing capital allocation and loss can be taken as an important purpose, it can reduce a lot of expenses for manufacturers and cause many economic benefits for manufacturers.

3. During the period of sheet metal processing, in order to ensure the purpose of reducing the allocation of funds, the staff must strictly abide by the production and processing specifications to carry out their work responsibilities. Before each processing, they must first review the application of raw materials. If there is no basis for approval, they cannot be processed casually. Extravagance and waste caused by many processing, production and manufacturing fields are due to the failure to establish the raw materials before processing. Therefore, the staff must first establish the types of processed raw materials and check the specifications and models of the raw materials. Making sufficient initial preparations can avoid negligence during the processing period and reduce the amount of waste parts. The staff should pay attention to such difficulties when processing at ordinary times.

Problems and Solutions of 2. Sheet Metal Stamping Parts

1. Burr: In the whole process of punching machine or cutting edge, the corner surplus material is not completely left, and the burr caused by the position under the broken surface of thick steel plate is taken as the standard. When the aspect ratio of burr is about 0.3mm, the copper powder generated will destroy the grinding tool and cause unevenness.

2. The broken pipe material will or may wrinkle the edge: the guiding roller of the unwinder line will cause the wrinkle scene caused by the gap between the guiding roller on the grinding tool and the bell, which is caused by the tenacious balance of the pipe material.

3, drag print: because the drag caused by the roller, and most of them are produced when suddenly terminated or accelerated.

4 Scratches: The key reason for causing scratches on parts is that sharp scars on abrasive tools must have metal dust falling into abrasive tools. The countermeasures to avoid scratches are to sharpen scars on abrasive tools and eliminate metal dust.

4. Concave-convex: abnormal protrusions or dents appear on the surface of the material, which is caused by the infiltration of dirt (iron pins and dust) into the unwinder line.

5. Bottom cracking: The key reason for the bottom cracking of the parts is that the plastic deformation of the raw material is weak or the grinding tool hemming strip is too tight to be extruded. The countermeasures are to replace the raw material with good plastic deformation or to release the hemming strip under some pressure.

6. Roller printing: it is caused by cleaning the roller or feeding roller sticking dirty things (generated by fixed pitch diameter), but under normal circumstances, the roller printing dirty things on the steel plate can only be removed.

7. Wrinkles on the outer wall: The key reason for wrinkles on the outer wall of the parts is the insufficient thickness of the raw materials (the smaller allowable thickness is still thinner) or the axial force occurs during the installation of the upper and upper dies, resulting in a large gap on one side and a small gap on the other side. Its avoidance countermeasure is to disassemble and replace the raw materials in time or adjust the grinding tool again.

8. Numerical control processing technology is the application obtained on the numerical control lathe of sheet metal parts. Numerical control processing technology deals with some difficult problems such as high precision, complicated appearance and large quantity of parts existing in sheet metal processing. cnc machine tool sheet metal parts cnc lathe, it contains cnc shearing machine, cnc machine fiber laser cutting, cnc machine tools, cnc machine bending machine, automatic welding machine, cnc flame cutting and other cnc lathe. Their use in manufacturing has further improved the ability of sheet metal processing, ensured the quality and production of sheet metal, and reduced the labor efficiency of workers much better.
