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

The oil from the upper oil collecting pipe is divided into two strands due to the internal structure of the actual heat sink

Analyze and simulate the flow and temperature on the surface of the heat sink. The fin radiator is composed of independent parallel oil flow channels, and each channel is composed of three connected small channels. The overall film length and film width diagram is a simplified model of the fin radiator. Export the simulated data to obtain a cloud map of its temperature distribution. On the horizontal line, the viscosity increases from the middle to the two sides, and some of the viscosity increases in the longitudinal direction, which proves that the speed of the oil in the oil passage decreases from the middle to the two sides. From the figure, the temperature distribution of the oil gradually decreases from the middle oil channel to the two sides. The isotherm is a downward convex curve, and in the longitudinal direction, the temperature gradually decreases.

Infrared wall temperature analysis. Taking the infrared camera on the upper surface of the heat sink, the following figure is obtained. As can be seen from the figure, the wall temperature gradually decreases from top to bottom. On the same horizontal line, there is a trend of high in the middle and low on both sides, but slightly in the middle of * It is lower than the oil passages on both sides. This is due to the internal structure of the actual heat sink. The oil from the upper oil collecting pipe is divided into two strands, and most of it flows into the oil passages on both sides of the middle. The length of each flow channel increases from the middle to the two sides, so the resistance also increases accordingly, so such a temperature cloud picture appears. It can be seen that the simulation and experimental results are basically consistent. It can be seen from the simulation and infrared cloud chart that most of the oil flows through the middle oil passage, and the flow rate is fast. Not only the flow on both sides is small, but the large resistance leads to the slow flow rate of the oil. Although the heat dissipation capacity on both sides is good, the overall heat dissipation is not effectively. The figure and the figure are the improved heat sink shape simulation temperature distribution cloud diagram. The improved fin shape improves the overall oil flow distribution and improves the heat dissipation efficiency. Therefore, appropriately increasing the flow on both sides or shortening the length of the oil flow channels on both sides can increase the heat dissipation effect.
