How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

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

Simulated radiator heat transfer performance comparison table Simulated radiator resistance performance comparison

 

From the simulation data of the double-drain pipe type radiator, the wave distance can be known from the simulation data. The water flow rate of the first drain pipe is basically the same, but the heat dissipation capacity of the second drain pipe is obviously smaller than that of the first row, which is only the first row. The simulation results found that after the cooling air exchanges heat with the second drain pipe, the temperature rises, and the temperature of the air inlet that exchanges heat with the second drain pipe increases, so that the average temperature difference between water and air in the second drain pipe decreases. According to the knowledge of heat transfer, the heat dissipation coefficient of the radiator is related to the average temperature difference between water and air, which is why the heat dissipation of the first drain pipe is significantly smaller than that of the first row. Comparison of results and conclusions The analysis table and table are the comparison of heat transfer performance and resistance performance of single drain pipe and double drain pipe radiator.

Table simulated radiator heat transfer performance comparison table simulated radiator resistance performance comparison can be seen from the table, although the heat dissipation area of ​​the double drain pipe radiator is twice that of the single drain pipe radiator, but under the same working conditions, the double drain Compared with the single drain pipe type, the heat dissipation of the pipe type is only increased, but the wind resistance is nearly doubled. At the same time, the material used to manufacture the double drain pipe type radiator is also the same as the single drain pipe type, so the quality and manufacturing cost of the radiator will increase accordingly. Considering the heat transfer performance, resistance performance, economy and reliability of the radiator, it is not the most effective method to increase the number of water pipe rows to increase the heat dissipation of the radiator. In the actual design of automobile radiators, the improvement of the heat transfer coefficient of the tube-strip radiator should be considered from the aspects of optimizing the structural design of the radiator and improving the manufacturing process. Through the heat transfer wind tunnel test and numerical simulation study of a commercial vehicle tube belt radiator, according to the comparison and analysis of the simulation results, under the same working conditions, the double drain pipe type only increases the heat dissipation than the single drain pipe type. , While the wind resistance has nearly doubled, and the manufacturing materials have also nearly doubled. Therefore, considering the heat exchange performance, resistance performance, economy and reliability of the radiator, it is not the most effective method to increase the number of water pipe rows to increase the heat dissipation of the radiator.
