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

When the pressure in the box is released to be less than the compression elastic force of the thin steel plate


The ND2 locomotive is an early diesel locomotive imported from Romania in the early 1970s. In the design of its diesel engine crankcase explosion-proof device, it is required that when the temperature and pressure of the oil and gas in the box rise and reach the set value due to certain abnormal conditions, several explosion-proof membranes arranged around the crankcase will be broken, causing high temperature, High-pressure oil and gas are released into the machine room to relieve the pressure in the box. However, if the continuous release of oil and gas in a short period of time causes the oil and gas to be filled in the machine room, it is very easy to cause a big explosion in the entire machine room and cause heavy losses. Therefore, the design of the protective device of the crankcase has a large defect. In recent years, ND2 locomotives have experienced 7 explosion accidents caused by the continuous release of oil and gas in the crankcase of the diesel engine. The crankcase was deformed by the explosion, the roof of the locomotive was blown up, and four explosions occurred during the operation of the locomotive. These explosions not only caused heavy losses to the locomotive, but also directly endangered driving safety.

ND2 locomotive diesel engine crankcase protection device and its working principle ND2 locomotive diesel engine is equipped with 2 sets of crankcase protection device, college of diesel locomotive major, bachelor degree, now engaged in diesel engine technology work. That is, explosion-proof valve and exhaust device. Explosion-proof valve The crankcase of ND2 locomotive diesel engine is equipped with 9 sets of explosion-proof valves, which are distributed around the crankcase. There is a 0.5mm thick arc-shaped thin steel plate between the explosion-proof valve cover and the intermediate body. The upper end of the steel plate is fixed on the explosion-proof valve by means of 3 bolts on the cover, and the lower end is pressed under the rectangular hole of the intermediate body by its own arc-shaped elastic force. The inside of the rectangular hole of the intermediate body is covered with a 0.05mm thick polyvinyl chloride fiber film, which separates the oil and gas in the crankcase from the atmosphere between the machinery outside the box. When the oil and gas pressure in the crankcase of the diesel engine rises to the set value due to some abnormal situation, the high-pressure oil and gas will break through the sealing film and open the thin steel plate to quickly release the high-pressure oil and gas in the box to the machine room outside the box. When the pressure in the box is released to less than the pressing elastic force of the thin steel plate, the thin steel plate is then pressed back to its original position, sealing the rectangular hole of the intermediate body, preventing the oil and gas in the box from continuing to diffuse between the machines.
