Description

Technical Field

[0001] The utility model relates to the technical field of processing molds, in particular to the technical field of forging and forming molds.

Background Art

[0002] An automobile is a vehicle that has its own power to be driven, does not need to rely on tracks or power lines, and can travel motorized. Generally speaking, a vehicle driven by its own mechanical energy is commonly called an automobile.

[0003] In the field of automobiles, the aluminum heat dissipation plate in the automobile electrical box plays a crucial role. Because the electronic devices inside the automobile electrical box generate heat during operation, if this heat cannot be dissipated in time, it will cause the equipment to overheat, which will in turn affect the performance and lifespan of the equipment. Due to its excellent thermal conductivity, the aluminum heat dissipation plate can effectively conduct the heat inside the electrical box out, and through heat exchange with the external environment, it helps to reduce the temperature inside the electrical box. This not only helps to protect the electronic devices inside the electrical box from overheating damage, but also ensures the stable operation of the automobile electrical system.

[0004] Currently, stamping dies are usually used for stamping and forming aluminum heat dissipation plates during the production process. However, the existing stamping dies have a simple structure and single function. Each time the die is closed for stamping, only one process can be completed. To complete the processing of heat dissipation plates with multiple processing steps, multiple sets of dies are required to complete all the processings, which not only has low productivity but also high production costs.

[0005] To solve the problems raised in the background art, for example, the patent application No. CN201620039613.0 discloses an aluminum heat dissipation plate forming die, including an upper die and a lower die. Between the upper and lower dies, a first punching station, a second punching station, a chamfering station, a sinking groove punching station, a notch cutting station, a pre-bending station, a bending station, and a blanking station are sequentially arranged from left to right; a first groove is provided at the pre-bending station of the lower die, and a raised trapezoidal convex block is provided in the middle of the first groove. A hemming punch for pressing and bending the two side arms of the heat dissipation plate downward is provided at the pre-bending station on the upper die. By setting multiple processing stations, multiple processes can be completed in one die closing. However, this device still has the following defects:

[0006] 1. Since the device lacks fixing columns to align and limit the upper die and the lower die, the product is prone to inaccurate stamping during the stamping process, resulting in a reduction in production quality.

[0007] 2. This device uses traditional compression springs. Traditional compression springs themselves have the disadvantage of making stamping unstable. For some products with high stamping accuracy requirements, stamping dies with compression springs cannot meet the production requirements. At the same time, the product needs to be manually taken out after processing, and the operation is relatively cumbersome.

Summary of the Utility Model

[0008] The purpose of the present utility model is to solve the problems in the prior art and propose a forging and forming die, which can align and limit through fixing holes and fixing columns, enabling the lower die base and the upper die base to be more accurate during die closing, and setting an upper stripping nitrogen spring to be more stable during stamping.

[0009] To achieve the above purpose, the present utility model proposes a forging and forming die, including a lower die base, an upper die base, guide columns, fixing blocks, die cushion blocks, forging and forming female dies, punch cushion blocks, and forging and forming male dies. The lower die base and the upper die base are symmetrically arranged up and down. There are four guide columns arranged between the lower die base and the upper die base. The lower die base and the upper die base are closed by the telescopic movement of the guide columns. A fixing block is arranged in the middle above the lower die base. A die cushion block is arranged above the fixing block. A forging and forming female die is arranged above the die cushion block. A punch cushion block is arranged in the middle below the upper die base. A forging and forming male die is arranged below the punch cushion block. The forging and forming male die and the forging and forming female die are arranged correspondingly.

[0010] Preferably, a stripping movable cushion block is arranged inside the fixing block. A plurality of lower stripping ejector rods are vertically arranged above the stripping movable cushion block. One end of the lower stripping ejector rod penetrates through the inside of the die cushion block and is connected with an upper stripping ejector rod. One end of the upper stripping ejector rod penetrates through the inside of the forging and forming female die and extends upward.

[0011] Preferably, upper stripping nitrogen springs are symmetrically arranged on both sides inside the punch cushion block.

[0012] Preferably, a forming cavity in a square structure is arranged in the middle above the forging and forming female die.

[0013] Preferably, a groove adapted to the forming cavity is arranged in the middle below the forging and forming male die.

[0014] Preferably, four fixing holes are annularly arranged on the upper surface of the forging and forming female die.

[0015] Preferably, four fixing columns are annularly arranged on the lower surface of the forging and forming male die. Each fixing column corresponds to a fixing hole.

[0016] The beneficial effects of the present utility model:

[0017] 1. By using the cooperation of the fixing holes and the fixing columns, the utility model can improve the production quality. After placing the product in the forming cavity on the forging and forming female die, start the external driving power supply, and then drive the upper die base to descend. During the descent of the upper die base, the punch pad is driven to descend, and the punch pad drives the forging and forming punch to descend. Since four fixing columns are annularly arranged on the lower surface of the forging and forming punch and correspond to the lower fixing holes, when the forging and forming punch descends, the four fixing columns are driven to insert into the four fixing holes on the forging and forming female die, thus playing a role of alignment and limiting, making the forging and forming punch and the forging and forming female die aligned when closing the die, thereby improving the processing quality of the product and avoiding the situation of inaccurate stamping. It solves the problem that the lack of fixing columns cannot align and limit the upper die and the lower die, resulting in inaccurate stamping of the product during the stamping process.

[0018] 2. By setting the upper stripping nitrogen spring, on the one hand, the upper stripping nitrogen spring replaces the traditional compression spring, which can simplify the structure of the stamping die, making the installation and disassembly of the stamping die more convenient. Moreover, the upper stripping nitrogen spring has an elastic structure with smoother buffering than the traditional compression spring and a longer service life than the traditional compression spring. Therefore, the upper stripping nitrogen spring can make the stamping die more stable during stamping and make the stamping die suitable for parts with higher stamping accuracy requirements. On the other hand, when the product gets stuck in the groove, nitrogen can be injected into the spring interior through an external tool to make it filled with nitrogen. Nitrogen has elasticity and can be compressed and expanded, thus realizing the function of the upper stripping nitrogen spring to eject the product. The upper stripping nitrogen spring solves the problem that the traditional compression spring itself causes unstable stamping.

[0024] Refer to Figure 1 , a forging die of the present utility model, a stripping movable cushion block 9 is arranged inside the fixing block 4. A plurality of lower stripping ejector rods 10 are vertically arranged above the stripping movable cushion block 9. One end of the lower stripping ejector rod 10 penetrates through the inside of the die cushion block 5 and is connected with an upper stripping ejector rod 11. One end of the upper stripping ejector rod 11 penetrates through the inside of the forging die cavity 6 and extends upward. After the product is stamped and formed, the stripping movable cushion block 9 is driven to rise by an external air cylinder, and then the lower stripping ejector rod 10 is driven to rise. The lower stripping ejector rod 10 drives the upper stripping ejector rod 11 to rise, so that the product is ejected from the forming cavity 61, which is convenient for the staff to take and improves the work efficiency.

[0025] Refer to Figure 1 , a forging die of the present utility model, upper stripping nitrogen springs 12 are symmetrically arranged on both sides inside the punch cushion block 7. By arranging the upper stripping nitrogen springs 12, the upper stripping nitrogen springs 12 replace the traditional compression springs, which can simplify the structure of the stamping die, make the installation and disassembly of the stamping die more convenient. Moreover, the upper stripping nitrogen springs 12 have an elastic structure with more stable buffering than the traditional compression springs and a longer service life than the traditional compression springs. Therefore, the upper stripping nitrogen springs 12 can make the stamping die more stable during stamping.

[0026] Refer to Figure 2 and Figure 3 , a forging die of the present utility model, a forming cavity 61 with a square structure is arranged in the middle above the forging die cavity 6. A groove 81 adapted to the forming cavity 61 is arranged in the middle below the forging punch 8. By the cooperation of the forming cavity 61 and the groove 81, the product can be formed evenly and with high quality.

[0027] Refer to Figure 2 and Figure 3, a forging die of the present utility model, four fixing holes 62 are annularly arranged on the upper surface of the forging concave die 6, four fixing columns 82 are annularly arranged on the lower surface of the forging convex die 8, and each fixing column 82 corresponds to the fixing hole 62. Since four fixing columns 82 are annularly arranged on the lower surface of the forging convex die 8 and correspond to the fixing holes 62 below, when the forging convex die 8 descends, the four fixing columns 82 are driven to insert into the four fixing holes 62 on the forging concave die 6, thereby playing a role of alignment and limitation, enabling the forging convex die 8 and the forging concave die 6 to be aligned during die closing, and thus improving the processing quality of the product.

[0028] Working process of the present utility model:

[0029] During the working process of a forging die of the present utility model, after placing the product in the forming cavity 61 on the forging concave die 6, start the external driving power supply, and then drive the upper die base 2 to descend. During the descent of the upper die base 2, the punch pad 7 is driven to descend, and the punch pad 7 drives the forging convex die 8 to descend. Since four fixing columns 82 are annularly arranged on the lower surface of the forging convex die 8 and correspond to the fixing holes 62 below, when the forging convex die 8 descends, the four fixing columns 82 are driven to insert into the four fixing holes 62 on the forging concave die 6, thereby playing a role of alignment and limitation, enabling the forging convex die 8 and the forging concave die 6 to be aligned during die closing, and thus improving the processing quality of the product.

[0030] By setting the upper stripping nitrogen spring 12, on the one hand, the upper stripping nitrogen spring 12 replaces the traditional compression spring, which can simplify the structure of the stamping die, make the installation and disassembly of the stamping die more convenient, and the upper stripping nitrogen spring 12 has an elastic structure with more stable buffering than the traditional compression spring and a longer service life than the traditional compression spring. Therefore, the upper stripping nitrogen spring 12 can make the stamping die more stable during stamping, make the stamping die applicable to parts with higher stamping accuracy requirements, and effectively extend the service life of the stamping die. On the other hand, when the product is stuck in the groove 81, nitrogen can be injected into the spring interior through an external tool to make it filled with nitrogen. Nitrogen has elasticity and can be compressed and expanded, thereby realizing the function of the upper stripping nitrogen spring 12 to eject the product.
