Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a novel double-layer stamping die for the production of automotive parts. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts (or semi-finished products). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts.

[0003] Because existing double-layer stamping dies for the production of new automotive parts process multiple sets of parts simultaneously, with high stamping frequency and intense metal-to-metal friction, they easily generate a large amount of heat, causing the die temperature to rise. Some devices cannot remove the excess heat in time, resulting in a decline in the material properties of the die due to prolonged high temperature. This increases the risk of die deformation and cracking, and reduces the working efficiency of the device. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that some double-layer stamping dies in the prior art cannot dissipate excess heat in time, causing the material properties of the die to deteriorate due to long-term high temperature, thereby increasing the risk of die deformation and cracking and reducing the working efficiency of the device. Therefore, a new type of double-layer stamping die for the production of automotive parts is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel double-layer stamping die for automotive parts production, comprising a base plate, a mounting rod fixedly connected to the surface of the base plate, a sliding block slidably connected to the surface of the mounting rod, a top plate fixedly connected to the top of the mounting rod, a mounting frame fixedly connected between the base plate and the top plate, a cooling device provided on the surface of the mounting frame, the cooling device comprising an electric telescopic rod, the electric telescopic rod being disposed at the bottom of the top plate, a first upper die fixedly connected to the bottom of the electric telescopic rod, a first lower die disposed at the bottom of the first upper die, two sets of the electric telescopic rod respectively fixed to the bottom of the top plate and the bottom of the first lower die, a water tank disposed on one side of the base plate, a water outlet pipe fixedly connected to the top of the water tank, a water pump fixedly connected to one side of the water outlet pipe, a cooling pipe fixedly connected to one side of the water pump, and the first upper die and the second lower die both fixedly connected between four sliding blocks.

[0006] Furthermore, a second upper mold is provided at the bottom of the first lower mold. A second lower mold is provided at the bottom of the second upper mold. The first lower mold is fixedly connected to the surface of the mounting rod, and both the second upper mold and the second lower mold are fixedly connected between four sliding blocks.

[0007] Furthermore, a second water pump is fixedly connected to the side of the cooling pipe away from the first water pump, and a condensation box is provided at the bottom of the second water pump, with a base plate on the side away from the water tank.

[0008] Furthermore, a connecting pipe is fixedly connected between the water tank and the condensation tank, and the connecting pipe is at the front end of the base plate.

[0009] Furthermore, a lead screw is rotatably connected inside the mounting bracket, and a drive bevel gear is fixedly connected to the bottom of the lead screw.

[0010] Furthermore, a driven bevel gear is meshed with one side of the driving bevel gear, and a lifting block is threaded onto the surface of the lead screw.

[0011] Furthermore, a motor is provided on one side of the active bevel gear, and the output end of the motor is fixedly connected to the inside of the active bevel gear. A fan is provided on the side of the lifting block near the cooling pipe.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, a cooling device is installed, which can drive the first upper mold and the second upper mold to move up and down via an electric telescopic rod. During the stamping process, water is drawn from the water tank through the outlet pipe by a water pump one, and then pumped into the cooling pipe by another water pump two. The water in the cooling pipe is then sent into the condensation tank for cooling. The cooled water is then returned to the water tank through a connecting pipe. This process is repeated to keep the water in the cooling pipe cool. Then, the output of the motor drives the driven bevel gear to rotate, which in turn drives the driving bevel gear to rotate, thereby driving the lead screw to rotate. At the same time, the lifting block is raised and lowered, and the fan is also raised and lowered during the raising and lowering process. This allows the cool air from the cooling pipe to be distributed throughout the entire device. The cooling device can effectively control the temperature of the mold during continuous stamping. Double-layer stamping molds process multiple parts simultaneously, with high stamping frequency and intense metal-to-metal friction, which easily generates a lot of heat, causing the mold temperature to rise. The cooling device can remove excess heat in time, preventing the mold from deteriorating due to prolonged high temperature, thereby reducing the risk of mold deformation and cracking, and extending its service life.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a novel double-layer stamping die for the production of automotive parts, including a base plate 1, a mounting rod 2 fixedly connected to the surface of the base plate 1, a sliding block 3 slidably connected to the surface of the mounting rod 2, a top plate 4 fixedly connected to the top of the mounting rod 2, a mounting bracket 5 fixedly connected between the base plate 1 and the top plate 4, and a cooling device 6 provided on the surface of the mounting bracket 5.

[0022] The specific setup and function of its cooling device 6 will be described in detail below.

[0023] In this embodiment: the cooling device 6 includes an electric telescopic rod 61, which is located at the bottom of the top plate 4. The bottom of the electric telescopic rod 61 is fixedly connected to a first upper mold 62, and the bottom of the first upper mold 62 is provided with a first lower mold 63. A water tank 66 is provided on one side of the bottom plate 1, and a water outlet pipe 67 is fixedly connected to the top of the water tank 66. A water pump 68 is fixedly connected to one side of the water outlet pipe 67, and a cooling pipe 69 is fixedly connected to one side of the water pump 68. The first upper mold 62 and the second lower mold 65 are both fixedly connected between four sliding blocks 3.

[0024] Specifically, a second upper mold 64 is provided at the bottom of the first lower mold 63. A second lower mold 65 is provided at the bottom of the second upper mold 64, and the first lower mold 63 is fixedly connected to the surface of the mounting rod 2.

[0025] Specifically, a second water pump 610 is fixedly connected to the side of the cooling pipe 69 away from the first water pump 68. A condenser box 611 is provided at the bottom of the second water pump 610, and the condenser box 611 is provided with a base plate 1 on the side away from the water tank 66.

[0026] Specifically, a connecting pipe 612 is fixedly connected between the water tank 66 and the condenser 611, and the connecting pipe 612 is at the front end of the base plate 1.

[0027] Specifically, the mounting bracket 5 is internally rotatably connected to a lead screw 613, and the bottom of the lead screw 613 is fixedly connected to a drive bevel gear 615.

[0028] Specifically, the driven bevel gear 616 is meshed with one side of the driving bevel gear 615, and the lifting block 614 is threadedly connected to the surface of the lead screw 613.

[0029] Specifically, a motor 617 is provided on one side of the active bevel gear 615, and the output end of the motor 617 is fixedly connected to the inside of the active bevel gear 615. A fan 618 is provided on the side of the lifting block 614 near the cooling pipe 69.

[0030] The effect achieved by the above components is as follows: by setting up the cooling device 6, water is drawn out of the water tank 66 by the water pump 68 through the water outlet pipe 67, and then the water is pumped into the cooling pipe 69 by the water pump. Then the water in the cooling pipe 69 is pumped into the condenser 611 by the water pump 610 for cooling. Finally, the cooled water is pumped into the water tank 66 through the connecting pipe 612. This process is repeated to keep the water in the cooling pipe 69 in a cooled state. The stable temperature environment can ensure the processing accuracy of the stamped parts. High temperature may cause the mold to expand and contract with temperature, changing its original size and shape, which may lead to problems such as size deviation and irregular shape of the stamped parts.

[0031] Working principle: By setting up a cooling device 6, the first upper mold 62 and the second upper mold 64 can be moved up and down by an electric telescopic rod 61. During the stamping process, water is drawn from the water tank 66 by a water pump 68 through the outlet pipe 67, and then pumped into the cooling pipe 69. The water is then pumped into the condenser 611 by a second water pump 610 for cooling. The cooled water is then returned to the water tank 66 through the connecting pipe 612. This process is repeated to keep the water in the cooling pipe 69 in a cooled state. Then, the output of the motor 617 drives the driven bevel gear 616 to rotate. During the process, the active bevel gear 615 will rotate, which will drive the lead screw 613 to rotate. At the same time, the lifting block 614 will rise and fall. During the rising and falling process, the fan 618 will also rise and fall, so that the cool air from the cooling pipe 69 can be dissipated to the entire device. The cooling device 6 can effectively control the temperature of the mold during the continuous stamping process. Because the double-layer stamping mold processes multiple sets of parts at the same time, the stamping frequency is high and the friction between metals is intense, which easily generates a lot of heat and causes the mold temperature to rise. The cooling device 6 can remove excess heat in time, avoid the material properties of the mold to deteriorate due to long-term high temperature, thereby reducing the risk of mold deformation and cracking and extending its service life.
