What causes mold bursting during the processing of non-standard parts?
What causes mold rupture in the processing of irregular parts? Irregular parts processing mainly uses a stamping die and the pressure of a press to stamp metal or non-metal sheet materials. It has the following characteristics: Irregular parts processing is stamped with low material consumption, the parts are light in weight, and have good rigidity. After the plastic deformation of the metal sheet, the internal organizational structure of the metal is improved, thereby improving the strength of the metal stamping parts. Stamping parts have high dimensional accuracy, consistent with the module size, and good interchangeability. They can meet the requirements of assembly and use without further processing. During the stamping process of irregular parts, the surface of the material is not damaged, so it has good surface quality, smoothness and beautiful appearance, which provides convenient conditions for surface spraying, electroplating and other surface treatments. Mold cracking is a common occurrence in the processing of irregular parts, but in severe cases, the template suddenly breaks into several pieces. Perhaps there are many reasons that lead to the immediate cracking of the mold, from the purchase of stamping die raw materials to the stamping operation process, all of which can cause damage to it. The reasons for mold cracking during the processing of irregular parts are: 1. Unsatisfactory blanking. No demagnetizing liquid was used before production, no return prompt; there were broken needles, broken springs, yellowing and other sticky materials during production;

What are the design principles and testing methods for the processing of non-standard parts?
What are the design principles and testing methods for the processing of irregular parts? Design principles for processing irregular parts: 1. The processing of irregular parts must meet the product's use and technical performance, and be easy to assemble and maintain. 2. The processing of irregular parts should help improve the utilization rate of metal materials, reduce the variety and specifications of materials, and lower material consumption as much as possible. If possible, low-cost materials should be used to minimize waste in parts blanking. 3. The processing of irregular parts should have a simple shape and reasonable structure to simplify the mold structure and the number of processes. The entire part should be processed using few and simple stamping processes, reducing other methods, which is beneficial for stamping operations and facilitates the implementation of mechanized and automated production, improving labor productivity. 4. Under the condition that the designed stamped parts can be used normally, the dimensional accuracy grade and surface roughness grade requirements should be as low as possible to facilitate product interchangeability, reduce defective products, and ensure stable product quality. 5. The processing of irregular parts should make the best use of existing equipment, process equipment, and processes, and extend the service life of stamping dies. Testing methods for processing irregular parts: A Rockwell hardness tester is used to test the hardness of processed irregular parts. Small stamped parts with complex shapes can also be tested using this method.

What is the process of machining irregular parts? How to prevent corrosion and conduct acceptance inspection? Let's talk about the machining of irregular parts.
Special-shaped parts processing. With the rapid development of the machinery industry, the fastener industry has become increasingly popular, and special-shaped fasteners are also becoming more and more common. For some entrepreneurs, special occasions will use special fasteners, which proves the importance of special-shaped fasteners. The production of special-shaped fasteners is very important, but before manufacturing, manufacturers need to follow customer needs and special regulations. In what cases do you need to customize special-shaped fasteners? Let's talk about special-shaped parts processing below. Fasteners are of two types: standard fasteners and non-standard fasteners. Non-standard fasteners are also called special-shaped parts. For example, the nuts we commonly use in our lives, nuts and bolts can be screwed together to fasten an object or part. Nuts and bolts are used in mechanical production, real life or other parts. They are indispensable accessories, and there are many kinds of nuts. Nuts can be divided into high-strength, stainless steel, carbon steel, and plastic steel according to different materials. According to the nature of the nut, there are standard nuts and non-standard nuts. Standard nuts are internationally standardized models, commonly known as ordinary bolts. Non-standard nuts are special nuts, with many uses and types in models outside the national standard. When the nuts we use in our daily lives cannot find the corresponding model in ordinary nuts, special nuts will be used for tightening. Manufacturers need to meet customer

Characteristics of a square and round ventilation duct?
Every thing has its value. In our daily life, there are many indispensable things and products. In the industrial field, there are also many mechanical equipment playing their roles in different fields, and S136 die steel is no exception. Today, let's talk about the applications of ventilation ducts. If you are interested, please continue to read on. The ventilation ducts are classified as ducts because they are primarily used for ventilation and cooling. This is the name it is used for, but it can be used in other places, even for drainage, liquid drainage or as containers, it cannot be called a pipe. According to the structure naming, it should be called spiral interlocking thin-walled pipe. Since ventilation ducts are mainly made of metal, they are called spiral seam metal pipes. If named by material, there may be these names: galvanized (iron) spiral pipes, stainless steel spiral pipes, aluminum spiral pipes, or in order to distinguish from existing stainless steel pipes, it can be called stainless steel pipes, because it can be rolled from 0.3mm or even thinner stainless steel strips. Compared with traditional hand-made iron pipes, mechanical spiral ducts have the following advantages: good sealing. Both strength and rigidity are very good. Low ventilation resistance and low ventilation noise.

The function of a square and round ventilation pipe?
With the rapid development of world science and technology, processing technology has become increasingly familiar to people, green manufacturing is highly valued, and the manufacturing of square-to-round ventilation ducts has also reached a new stage. So what should we pay attention to during use? The main function of the square-to-round ventilation duct is to connect the square pipe and the round pipe. The shape of the upper and lower parts of the pipe fitting is circular and square. Generally applicable to special structural components. Square-to-round ventilation ducts have flat bottoms, bends, and cones. For example, the connection between circular ventilation ducts and fan outlets, air conditioning units and fan inlets, etc. This welded pipe fitting is widely used in many industries, such as the connection of anti-corrosion steel pipe systems, and some large welded structural parts, but it is more widely used in fan and ventilation and air conditioning systems. When using the square-to-round ventilation duct, first draw a straight line, draw a vertical line segment at one end, take the height of the square-to-round, and set the length proportionally on the line segment. Then, use the hypotenuse projection length on the top view as the base, and the hypotenuse length of the triangle is drawn, which is the actual length. In this figure, the line segments required for the angle are drawn. Do the same and draw the required line segments for the four corners. Ventilation ducts are used in industrial and civil buildings.
