What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

Notice on Simplified Structural Design of Machined Parts (Surface Grinding or Precision Planes)

Most metal mechanical parts are machined before they are used for official use. This is the final step before assembling the machine parts. Therefore, the quality and cost of machining has a great impact on the quality and cost of machine parts and the machine as a whole. Therefore, the design process must consider the machining process.

Especially for some special mechanical parts, the manufacturing process is often very special and requires special consideration in the design. The ability to manufacture a part is a decisive factor in the adoption of a design. Therefore, the following issues should be noted when designing the structure of these machined parts:

1. Structural design of parts to save materials

Table of Contents

Note that it reduces the blank size. The flange is made directly of round steel. If the maximum diameter of the design is 100 mm, it should be treated with 105 mm or 110 mm round steel. If the maximum diameter of the design is 98mm, it can be processed with 100mm steel, saving a lot of steel.

2. Structural design to reduce the amount of machining

(1) Consider the effect of cast error

The error in the cast part is relatively large and should be taken into consideration when designing the cast surface. For example, the bearing end cover matches the boss of the box body, but it is difficult to position the boss of the box body very accurately. If the diameter of the end cap flange is designed to be exactly equal to the diameter of the convex platform, the effects of casting errors often result in the end cap protruding beyond the convex platform. Therefore, the diameter of the casting boss should be large.

(2) Surfaces with different processing accuracy must be processed individually.

If the two surface roughness requirements are different, there must be a clear boundary between the two surfaces. It is not only easy to process, but also beautiful in shape.

3. Reduce the structural design of manual processing or supplementary processing

(1) Replace manual grinding with surface grinding

The universal tool microscope guideway for large optical measuring instruments was originally designed as a circular guideway used for manual guidance and then changed to a flat V guideway. Processed with a surface grinding machine, productivity has been greatly improved.

(2) Replace the scraper box with a surface grinding machine or fine planer.

The split surface of the split gearbox case must have a high degree of flatness. Some production units use heavy workload and low productivity manual scraping. Later, it was changed to a surface grinding machine for processing live fine planers.

4. Simplify the shape and requirements of the machined surface

(1) It is necessary to avoid non-circular parts with a stop fit.

There is a flange on the surface of the box part to fit it. To ensure the correct position of the cover. In addition to being screwed in, it is designed with a stop fit. Matching holes should be rounded and other shapes such as rectangles, squares and ovals are not suitable.

(2) Must be filled with chamfers of parts with complex shapes

Chamfering parts with complex shapes is difficult. As such an elliptical complex shape, it is difficult to chamfer by hand machining and chamfering, and it is difficult to guarantee the quality of the process.

5. Structural design of parts for easy clamping and measurement

To avoid the structure of parts that cannot be clamped, the machine parts must be clamped to the machine during machining, so the parts must be easily clamped to the machine parts. In addition, clamp parts need sufficient support to prevent them from shaking under the action of cutting forces. Therefore, the part is rigid enough to avoid clamp deformation.

6.To avoid cutting tools under unfavorable conditions

The tool can easily move in and out of the machined surface. A certain amount of moving space is required when the tool moves in and out of the machined surface. The design must maintain sufficient clearance.

7. Correctly handle the shaft and hole structure (inner and outer surfaces)

Complex machined surfaces are designed on the outer surface rather than the inner surface, and shaft parts are easier to machine than holes.

Therefore, if you combine two shafts and hole-shaped parts and there are some more complex structures between them, it is often better to design these structures on the axle rather than on the inner surface of the hole. ..
