Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a reinforcement structure for stamping dies. Background Art

[0002] Automobile chassis stamping dies are special tools used to produce structural parts such as automobile chassis. Automobile chassis and many other automobile parts, such as body, fuel tank, radiator fins, etc., are made through stamping process. Stamping is a metal processing method that forms metal sheets or strips into the required part shape in a die through stamping force. When manufacturing these stamping parts, the raw materials usually used are hot-rolled or cold-rolled steel plates and steel strips, which can be made into various automobile structures and covers after stamping. Automobile chassis stamping dies are an indispensable part of the automobile manufacturing process. The quality of their design and manufacturing directly affects the quality, safety and production cost of automobile products. When selecting and using these dies, it is necessary to comprehensively consider multiple aspects such as materials, design, technical requirements and environmental factors. With the development of technology, automobile chassis stamping dies are also constantly optimized and upgraded to meet the needs of more complex and sophisticated product design.

[0003] Automobile chassis stamping parts have the characteristics of large quantity, thick material and high strength, which often require high strength of stamping die blade. In addition, punching dies are affected by factors such as structure, which limits the size and thickness of the blade, greatly reducing the strength. Therefore, the die blade is easily damaged, which directly affects the production rhythm. Utility Model Content

[0004] The utility model aims to remedy the defects of the prior art and provide a reinforcement structure for a stamping die.

[0005] The utility model is realized by the following technical solutions:

[0006] A reinforcement structure for a stamping die comprises a fixing seat, a blade insert mounting groove is formed on one side of the fixing seat, a blade insert is embedded in the blade insert mounting groove, a punch punching groove is formed in the middle of the blade insert, a reinforcement boss integrally formed with the blade insert is provided on the top of the back side of the blade insert, and a reinforcement boss support block is integrally formed in the blade insert mounting groove.

[0007] A first convex block protruding outwards is arranged on the left side of the knife edge insert, and a second convex block protruding outwards is arranged on the right side of the knife edge insert.

[0008] A groove one matching with the first protrusion is formed on the left side of the blade insert installation groove, and a groove two matching with the second protrusion is formed on the right side of the blade insert installation groove.

[0009] An integrally formed mounting seat having a size larger than the fixing seat is provided below the fixing seat, and a mounting hole is provided on the mounting seat.

[0010] The advantages of the utility model are: the utility model has a reasonable structural design. First, by adding a reinforcing boss to the blade insert, the reinforcing boss simultaneously strengthens the strength of the blade insert itself; second, the boss surface is against the inner wall of the groove of the die fixing seat, and the inner wall has a good supporting effect on the boss, thereby supporting the entire blade insert to withstand the pressure brought by the punch.

[0017] like Figure 1-6 As shown, a reinforcement structure for a stamping die includes a fixing seat 1, a blade insert mounting groove 2 is opened on one side of the fixing seat 1, a blade insert 3 is embedded in the blade insert mounting groove 2, a punch punching groove 4 is opened in the middle of the blade insert 3, a reinforcement boss 5 integrally formed with the blade insert 3 is provided on the top of the back side of the blade insert 3, and a reinforcement boss support block 8 is integrally formed in the blade insert mounting groove 2.

[0018] A protrusion 1 6 protruding outward is provided on the left side of the knife edge insert 3, and a protrusion 2 7 protruding outward is provided on the right side of the knife edge insert 3.

[0019] A groove 9 matching with the protrusion 6 is provided on the left side of the blade insert installation groove 2, and a groove 10 matching with the protrusion 7 is provided on the right side of the blade insert installation groove 2, so as to increase the inlay contact area and improve the working stability.

[0020] An integrally formed mounting seat 11 having a size larger than the mounting seat is provided below the fixing seat 1, and a mounting hole 12 is provided on the mounting seat to increase the stability of the fixing seat.

[0021] A reinforcing boss 5 is designed on the back of the blade insert 3. When the blade insert 3 is inserted into the fixing seat 1, the reinforcing boss 5 is pressed against the inner wall of the fixing seat 1 and the reinforcing boss support block to support the pressure on the blade during the punching process.

[0022] The position of the reinforcement boss 5 does not affect the falling of waste materials, and the reinforcement boss surface and the fixing seat have sufficient contact surface and the contact surface is evenly distributed.

[0023] The reinforcing boss 5 also effectively increases the thickness of the blade insert 3 itself, thereby increasing the strength to withstand the pressure exerted on the blade during the punching process.

[0024] Through the design of the above structure, when the punch 13 in the mold punches into the blade surface (front) of the blade insert, a large impact force will be generated, and the reinforcing boss can effectively enhance the strength of the blade insert itself, while the fixing seat can effectively support the impact force received by the blade insert. Therefore, during the mold production process, the blade insert has sufficient strength to meet the production of automobile chassis stamping parts and meet production needs.
