Description

Technical Field

[0001] The utility model relates to the technical field of stamping devices, and specifically relates to an efficient pneumatic bumper stamping structure. Background Technique

[0002] An automobile bumper is a protective component installed at the front and rear parts of a vehicle. Its main function is to absorb energy during a collision or low-speed impact, protect the vehicle and its passengers from harm, and reduce damage to the vehicle structure. The production of automobile bumpers usually involves stamping processing as an important technological step, where pre-cut material sheets are stamped through a stamping device to form the shape of the bumper. During the stamping process, frictional heat and deformation heat are generated after the metal material is processed. To prevent the workpiece and the mold from overheating, avoid premature aging of the material, and improve the processing quality, it is usually necessary to control the temperature of the processing area through a cooling system.

[0003] After retrieval, it is found that the Chinese utility model patent with the application number 202320899488.0 discloses a stamping device for processing automobile bumpers, including a stamping machine main body. A hydraulic cylinder is arranged at the upper end of the stamping machine main body. An upper template is arranged on the hydraulic push rod of the hydraulic cylinder. A lower template is arranged below the upper template. A cooling pool is arranged on the stamping machine main body, and the cooling pool is located at the bottom of the lower template. The cooling pool includes an inner groove, a through groove, a water collecting groove, and a drainage hole. An inner groove is arranged inside the cooling pool. A water collecting groove is arranged between the inner groove and the cooling pool. A drainage hole is arranged on one side of the water collecting groove away from the inner groove. A water tank is arranged on one side of the stamping machine main body. The water tank is fixedly connected to the cooling pool through a circulating filtration component.

[0004] The above-mentioned utility model has the following problems:

[0005] 1. This technical solution mainly cools the mold by spraying the coolant in the water tank through a nozzle. However, due to the characteristic that water is not easily compressible, and the coolant sprayed on the mold easily causes the surrounding dust to adhere to the mold, which will affect the stamping effect of the workpiece, resulting in easy deviation of the size and surface shape of the stamped workpiece.

[0006] Therefore, those skilled in the art have provided an efficient pneumatic bumper stamping structure to solve the problems raised in the above background technique. Content of the Utility Model

[0007] The purpose of the present utility model is to provide an efficient pneumatic bumper stamping structure to solve the problems raised in the above background technique.

[0008] To achieve the above purpose, the present utility model provides the following technical solutions:

[0009] An efficient pneumatic bumper stamping structure includes a base, an upper die holder and a lower die holder. The lower die holder is fixedly installed at the upper end of the base. An upper female die is fixedly installed at the upper end of the lower die holder. Air holes one and two that penetrate into the grooves of the upper female die are respectively opened on the outer walls of the left and right sides of the upper female die. One ends of the air holes one and two are respectively threadedly installed with a first air nozzle and a second air nozzle. Fixing blocks one and two are respectively fixedly connected to the lower end of the upper die holder near the left and right sides. A fourth air nozzle is threadedly installed on the fixing block one, and a third air nozzle is threadedly installed on the fixing block two.

[0010] As a further solution of the present utility model: One end of the first air nozzle is fixedly connected to a first air pipe, one end of the second air nozzle is fixedly connected to a second air pipe, one end of the fourth air nozzle is fixedly connected to a fourth air pipe, and one end of the third air nozzle is fixedly connected to a third air pipe.

[0011] As a further solution of the present utility model: The other ends of the first air pipe, the second air pipe, the fourth air pipe and the third air pipe are all fixedly connected to an external air compressor.

[0012] As a further solution of the present utility model: Columns are fixedly installed at the positions of the upper end of the base near the four corners. The upper ends of the columns are fixedly installed with a top plate.

[0013] As a further solution of the present utility model: A hydraulic cylinder is fixedly installed at the upper end of the top plate through bolts. The output shaft of the hydraulic cylinder penetrates through the top plate and extends to the lower end of the top plate and is fixedly connected to the upper die holder.

[0014] As a further solution of the present utility model: A connecting plate is fixedly installed at the lower end of the upper die holder through bolts. The lower end of the connecting plate is integrally connected with an upper male die. The output ends of the third air nozzle and the fourth air nozzle both face the upper male die.

[0015] As a further solution of the present utility model: Guide sleeves are fixedly installed at the positions of the lower end of the upper die holder near the four corners. The inside of the guide sleeves penetrates through the top of the upper die holder.

[0016] As a further solution of the present utility model: Guide rods are fixedly connected to the positions of the upper end of the lower die holder near the four corners. The upper ends of the guide rods extend into the inside of the guide sleeves and are slidably connected to the inner walls of the guide sleeves.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] 1. By setting the first air nozzle, the second air nozzle, the third air nozzle and the fourth air nozzle, the present utility model can blow air into the inside of the upper male die and the upper female die during the process of the upper die holder lifting after stamping, thereby reducing the temperature of the processing area;

[0019] 2. In this utility model, the first air nozzle and the second air nozzle are connected to the inner bottom of the lower die through the first air hole and the second air hole. This not only can blow air into the interior of the lower die for cooling, but also plays a role in demolding. Usually during the stamping process, especially for workpieces with complex shapes or deep-drawn parts, demolding may be relatively difficult. By blowing air from the bottom of the lower die through the first air nozzle and the second air nozzle, air can be injected into the lower die, thereby forming a gas layer between the workpiece and the lower die, reducing friction and helping the workpiece to easily fall off the die.

[0020] 3. By blowing air into the machine box through the first air nozzle, the second air nozzle, the third air nozzle and the fourth air nozzle, the surfaces of the upper punch and the lower die can also be kept clean, and during the stamping process, the workpiece is not easily damaged.

[0029] Embodiment 2

[0030] Referring to Figures 1-4 , this embodiment is based on the previous embodiment. The difference from the previous embodiment is that one end of the first air nozzle 8 is fixedly connected to a first air pipe 801, one end of the second air nozzle 9 is fixedly connected to a second air pipe 901, one end of the fourth air nozzle 16 is fixedly connected to a fourth air pipe 1601, and one end of the third air nozzle 15 is fixedly connected to a third air pipe 1501. The other ends of the first air pipe 801, the second air pipe 901, the fourth air pipe 1601, and the third air pipe 1501 are all fixedly connected to an external air compressor. Columns 3 are fixedly installed at the positions near the four corners of the upper end of the base 1. A top plate 2 is fixedly installed at the upper end of the column 3. A hydraulic cylinder 4 is fixedly installed at the upper end of the top plate 2 by bolts. The output shaft of the hydraulic cylinder 4 penetrates through the top plate 2 and extends to the lower end of the top plate 2 and is fixedly connected to the upper die base 10. A connecting plate 11 is fixedly installed at the lower end of the upper die base 10 by bolts. An upper male die 12 is integrally connected to the lower end of the connecting plate 11. The output ends of the third air nozzle 15 and the fourth air nozzle 16 both face the upper male die 12.
