Technical Field

[0001] The utility model relates to the technical field of stamping die auxiliary devices, in particular to a stamping die with a cooling structure. Background Technique

[0002] A stamping die is a special process equipment that processes parts (metals or non-metals) into parts (or semi-finished products) in cold stamping processing, and is called a cold stamping die (commonly known as a cold punching die). Stamping is a pressure processing method that applies pressure to parts using a die installed on a press at room temperature to cause separation or plastic deformation, thereby obtaining the required parts.

[0003] There is no cooling auxiliary mechanism for cooling the die on the existing stamping die, and it can only perform stamping work intermittently. After working for a period of time, it pauses to cool down and then performs stamping again, which affects the overall work efficiency. Therefore, it is particularly important to design a stamping die with a cooling structure to solve the above technical problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that there is no cooling auxiliary mechanism for cooling the die on the existing stamping die, and it can only perform stamping work intermittently. After working for a period of time, it pauses to cool down and then performs stamping again, which affects the overall work efficiency, and a stamping die with a cooling structure is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A stamping die with a cooling structure includes a base, a concave die is fixedly connected to the base through a support seat, a convex die is movably connected above the concave die, guide columns are symmetrically installed on the base, a mounting plate is fixedly connected to the guide columns, a hydraulic cylinder is fixedly connected to the mounting plate, a sliding rod is slidably connected to the hydraulic cylinder, the end of the sliding rod is fixedly connected to the convex die, the convex die and the concave die fit with each other, a spring is installed on the outer wall of the support seat, and a sheet material is arranged between the convex die and the concave die.

[0006] Preferably, a plurality of radiating fins are fixedly connected to both sides of the concave die, a fan blade is installed on the concave die through a frame, a driving power supply is installed on one side of the concave die, and the driving power supply is connected to the fan blade through a cable.

[0007] Preferably, limiting frames are fixedly connected to both sides of the convex die, the limiting frames are slidably arranged on the guide columns, a positioning plate is fixedly connected to the limiting frames, and the positioning plate and the top of the concave die are at the same horizontal height.

[0008] Preferably, when the limiting frame and the positioning plate are in contact with each other, the convex die reaches the concave die to limit the convex die from continuing to descend.

[0009] Preferably, a turbo fan is fixedly connected to the base, an auxiliary power supply for power supply is arranged in the turbo fan, and both the punch and the die are made of heat-conducting materials.

[0010] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0011] 1. In the present utility model, during use, heat dissipation fin structures are evenly distributed on the outer walls on both sides of the die, and at the same time, fan blades are installed on both sides of the die. Driven by the corresponding drive power supply in cooperation with the fan blades, the heat generated on the heat dissipation fins is dissipated, so as to achieve the effect of cooling. Due to the turbo fan structure on the base, it directly acts on the positions of the punch and the die, driving the heat generated during stamping. Compared with the case where no heat dissipation device is provided conventionally, the technical solution adopted by the present utility model can dissipate the heat generated during stamping in time, extend the service life of the die, does not affect the efficiency of stamping processing, is directly installed on the die, optimizes the existing working space, and solves the problem that the existing stamping die is not provided with a cooling auxiliary mechanism for cooling the die, and can only perform stamping work intermittently. After working for a period of time, it pauses for cooling and then performs stamping again, affecting the overall working efficiency.

[0012] 2. In the present utility model, during use, the hydraulic cylinder drives the sliding rod to drive the punch to move downward until the limiting frame on the punch slides on the guide pillar until the limiting frame abuts against the positioning plate. At this time, the punch reaches the die, and the limiting punch continues to move downward. The sheet material drives the punch to move downward in cooperation with the die under the drive of the sliding rod, completing the stamping work on the sheet material. The mutual cooperation of the limiting frame and the positioning plate ensures the processing of the punch and the die in a relatively safe environment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0017] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0018] The present utility model provides a stamping die with a cooling structure, including a base 1. A female die 102 is fixedly connected to the base 1 through a support seat 101. A male die 203 is movably connected above the female die 102. Guide columns 103 are symmetrically installed on the base 1. A mounting plate 2 is fixedly connected to the guide columns 103. A hydraulic cylinder 201 is fixedly connected to the mounting plate 2. A sliding rod 202 is slidably connected to the hydraulic cylinder 201. The end of the sliding rod 202 is fixedly connected to the male die 203. The male die 203 and the female die 102 fit with each other. Springs 104 are installed on the outer wall of the support seat 101. A sheet material 6 is arranged between the male die 203 and the female die 102. Multiple groups of heat dissipation fins 3 are fixedly connected to both sides of the female die 102. A fan blade 4 is installed on the female die 102 through a frame 403. A driving power source 401 is installed on one side of the female die 102. The driving power source 401 and the fan blade 4 are connected through a cable 402. A turbo fan 502 is fixedly connected to the base 1. An auxiliary power source 503 for power supply is arranged in the turbo fan 502. Both the male die 203 and the female die 102 are processed from heat-conducting materials, which is beneficial to the subsequent heat dissipation work.

[0019] When a stamping die with a cooling structure is actually in use, before the stamping starts working, the staff controls the driving power supply 401 to cooperate with the fan blades 4 on both sides to rotate. The blown air flow directly acts on the heat sinks 3 on the female die 102, taking away the heat on the heat sinks 3. At the same time, it also drives the auxiliary power supply 503 to cooperate with the turbine fan 502 to work, generating an air flow that directly acts on the positions of the male die 203 and the female die 102, taking away the heat generated by the male die 203 and the female die 102 during stamping. When starting the stamping work, the hydraulic cylinder 201 drives the sliding rod 202 to drive the male die 203 to descend. Until the limit frame 5 on the male die 203 slides on the guide post 103 until the limit frame 5 abuts against the positioning plate 501, at this time the male die 203 reaches the female die 102 and the limit male die 203 continues to descend. The sheet material 6 drives the male die 203 to descend in cooperation with the female die 102 under the drive of the sliding rod 202, completing the stamping work on the sheet material 6. During the stamping process, the heat generated between the male die 203 and the female die 102 can be conducted out in time because both the male die 203 and the female die 102 are processed with heat-conducting materials. A plurality of heat sink 3 structures are installed on both sides of the female die 102. With the cooperation of the fan blade 4 structure, the heat on the heat sink 3 is blown out. By evenly distributing the heat sink 3 structure on the outer walls on both sides of the female die 102, and at the same time installing fan blades 4 on both sides of the female die 102, driven by the corresponding driving power supply 401 in cooperation with the fan blades 4, the heat generated on the heat sink 3 is dissipated, thus achieving the cooling effect. The turbine fan 502 structure on the base 1 directly acts on the positions of the male die 203 and the female die 102, taking away the heat generated during stamping. Compared with the case of a conventional stamping die without a heat dissipation device, the technical solution adopted by the present utility model can dissipate the heat generated by stamping in time, extend the service life of the die, does not affect the stamping processing efficiency, is directly installed on the die, and optimizes the existing working space.

[0020] As Figure 1-2 shown, limit frames 5 are fixedly connected to both sides of the male die 203. The limit frames 5 are slidably arranged on the guide posts 103. A positioning plate 501 is fixedly connected to the limit frames 5. The positioning plate 501 is at the same horizontal height as the top of the female die 102. When the limit frames 5 and the positioning plate 501 abut against each other, that is, when the male die 203 reaches the female die 102, the limit male die 203 continues to descend.

[0021] The effect achieved by the entire Embodiment 1 is that during use, the hydraulic cylinder 201 drives the sliding rod 202 to drive the punch 203 to move downward until the limiting frame 5 on the punch 203 slides on the guide pillar 103 until the limiting frame 5 abuts against the positioning plate 501. At this time, the punch 203 reaches the die 102 and the limiting punch 203 continues to move downward. The sheet material 6 drives the punch 203 to move downward in cooperation with the die 102 under the drive of the sliding rod 202, completing the stamping work on the sheet material 6. The mutual cooperation between the limiting frame 5 and the positioning plate 501 ensures the processing of the punch 203 and the die 102 in a relatively safe environment.

[0022] Working principle: Before the stamping work starts, the staff controls the drive power supply to cooperate with the fan blades on both sides to rotate, and the blown air flow directly acts on the heat sinks on the die, taking away the heat on the heat sinks. At the same time, it also drives the auxiliary power supply to cooperate with the turbine fan to work, generating an air flow that directly acts on the positions of the punch and the die, taking away the heat generated by the punch and the die during stamping. When starting the stamping work, the hydraulic cylinder drives the sliding rod to drive the punch to move downward until the limiting frame on the punch slides on the guide pillar until the limiting frame abuts against the positioning plate. At this time, the punch reaches the die and the limiting punch continues to move downward. The sheet material drives the punch to move downward in cooperation with the die under the drive of the sliding rod, completing the stamping work on the sheet material. During the stamping process, the heat generated between the punch and the die can be conducted out in a timely manner because both the punch and the die are made of heat-conducting materials. Multiple groups of heat sink structures are installed on both sides of the die, and the heat on the heat sinks is blown out under the cooperation of the fan blade structure.
