Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a continuous stamping die with rapid heat dissipation. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to create shaped articles. Stamping involves applying external force to various materials such as sheet metal, strip metal, and steel pipes using a press and mold, thereby changing their shape to achieve the desired shape and precision dimensions.

[0003] A search revealed a utility model patent with publication number CN220760777U, which discloses a stamping die for rapid and continuous stamping. The die includes a support frame with a limiting groove on its bottom inner wall. A die body is placed inside the limiting groove, and limiting components are provided on both sides of the die body. Each limiting component includes a support plate welded to the bottom inner wall of the support frame. A threaded rod is connected to one side of the support plate via a bearing. A moving rod is threaded to the outer wall of the threaded rod. An abutment plate is welded to one side of the moving rod, and a handle is welded to one end of the threaded rod. This stamping die for rapid and continuous stamping, through its limiting components, can prevent positional deviation during stamping, effectively ensuring the accuracy of the stamping position and improving the stamping quality of the workpiece. The ejector plate, in conjunction with the stamping components, allows for continuous stamping of the workpiece, effectively improving the die's processing efficiency.

[0004] While the aforementioned patents can prevent die misalignment during stamping by using limiting components, effectively ensuring stamping accuracy and improving the stamping quality of the parts, the friction between the die and the material, as well as the plastic deformation of the material, generate a large amount of heat during stamping. This heat is mainly caused by frictional heat and plastic deformation heat. Although the die itself has a certain heat dissipation capacity, after continuous stamping, a large amount of heat will be generated inside the die and on the stamping surface. The rise in die temperature will cause the die to expand, reducing the gap between the punch and die, increasing friction and stress, ultimately affecting the accuracy of the processed dimensions and shortening the die's service life.

[0005] Therefore, it is necessary to propose a continuous stamping die with rapid heat dissipation to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a continuous stamping die with rapid heat dissipation. Through the cooperation of the internal parts of the heat dissipation mechanism, the cooling fan can be driven to rotate and continuously blow air to dissipate heat on the surface of the die body during continuous stamping by the stamping head and the die body. This reduces the temperature of the die body during stamping, thus solving the problem in the prior art where a large amount of heat is generated inside and on the stamping surface of the die after continuous stamping. The increased die temperature leads to die expansion, a decrease in the gap between the punch and die, increased friction and stress, ultimately affecting the accuracy of the processing dimensions and shortening the die's service life.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a continuous stamping die with rapid heat dissipation, including a stamping table, a die body installed on the top of the stamping table, a heat dissipation mechanism connected and fixed between the stamping tables, distributed around the outer wall of the die body and located above the die body, and a clamping mechanism slidably connected to both sides of the inner wall of the die body, and penetrating the die body to the interior of the stamping table.

[0008] The heat dissipation mechanism includes multiple guide rods distributed around the outer wall of the mold body and mechanically fixed to the inner wall of the stamping table. A guide plate is sleeved on the outer wall of each guide rod and slidably connected to the outer wall of the guide rod. A support column is machined at the bottom end of the guide plate and extends through the interior of the guide rod. A drive shaft is rotatably connected to the side of the guide rod near the outer wall of the mold body and fits against the outer wall of the support column. A cooling fan is connected to the output end of the drive shaft. A protective net is sleeved and fixed on the outer wall of the cooling fan. A transmission gear is machined on the outer wall of the drive shaft.

[0009] The clamping mechanism includes a support plate, which is mechanically connected to the bottom end of the support column and slidably connected to the inside of the stamping table. A threaded screw is rotatably connected inside the stamping table and passes through the support plate to the inside of the mold body. A telescopic slider is sleeved on the outer wall of the threaded screw and slidably connected to the inside of the mold body.

[0010] Preferably, the clamping mechanism further includes clamping plates, and there are multiple clamping plates. The multiple clamping plates are slidably connected to both sides of the inner wall of the mold body and located on the top side of the telescopic slider. The bottom end of the clamping plate is machined with a limit plate, and a limit spring is connected and fixed between the limit plate and the inner wall of the mold body.

[0011] Preferably, the bottom end of the guide plate is bolted to a stamping head, and the top end is connected to a hydraulic cylinder and a hydraulic pump. The guide rod has a connecting groove inside that matches the support column.

[0012] Preferably, the outer wall of the support column is machined with a rack that matches the transmission gear, the transmission shaft and the cooling fan are rotatably connected to the outer wall of the guide rod through bearings, and the horizontal height of the cooling fan is consistent with the horizontal height of the mold body.

[0013] Preferably, the support plate and the telescopic slider have internal threads that match the outer wall threads of the threaded screw, and the threads connecting the top of the threaded screw and the telescopic slider rotate in opposite directions to the threads connecting the bottom of the threaded screw and the support plate. The stamping table has a support groove that matches the support plate, and the mold body has a telescopic groove that matches the telescopic slider.

[0014] Preferably, the top end of the telescopic slider and the bottom end of the clamping plate are both machined with matching conical surfaces, the mold body has a limiting groove inside that matches the limiting plate, and the surface of the clamping plate that contacts the workpiece is made of rubber.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By placing the stamped part on the mold body, the hydraulic cylinder is activated to drive the guide plate to move downward, which in turn drives the stamping head to move downward to complete the stamping work on the stamped part on the mold body. At the same time, the guide plate slides on the outer wall of the guide rod, which drives the support column to move. The movement of the support column drives the transmission gear to rotate through the rack. The rotation of the transmission gear drives the transmission shaft to rotate, which in turn drives the cooling fan to rotate. The cooling fan blows air to cool the mold body. Thus, when the mold body is continuously stamping, the reciprocating movement of the support column drives the cooling fan to rotate continuously to blow air to cool the mold body, which makes the air around the mold body flow rapidly, improves the heat dissipation of the mold body itself, and the air blowing by the rotating cooling fan can accelerate the heat dissipation efficiency of the mold.

[0017] 2. The guide plate moves downward, causing the support column to move. The support column moves, causing the support plate to move synchronously. The movement of the support plate drives the threaded screw to rotate. The rotation of the threaded screw drives the telescopic slider to slide upward. The telescopic slider moves upward and presses against the clamping plate. The clamping plate is forced to push the limit plate to compress the limit spring, causing the clamping plate to move and clamp and limit the stamping part at the top of the mold body, preventing the stamping part from shifting during the stamping process and causing the stamping quality to be unqualified.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5 The continuous stamping die with rapid heat dissipation shown includes a stamping table 1, a die body 101 mounted on the top of the stamping table 1, heat dissipation mechanisms 2 connected and fixed between the stamping tables 1, distributed around the outer wall of the die body 101 and located above the die body 101, and clamping mechanisms 3 slidably connected to both sides of the inner wall of the die body 101, and penetrating the die body 101 to the interior of the stamping table 1.

[0028] The heat dissipation mechanism 2 includes guide rods 201, and there are multiple guide rods 201 distributed around the outer wall of the mold body 101 and mechanically fixed to the inner wall of the stamping table 1. A guide plate 202 is sleeved on the outer wall of the guide rod 201 and slidably connected to the outer wall of the guide rod 201. A support column 203 is machined at the bottom end of the guide plate 202 and extends into the interior of the guide rod 201. A drive shaft 204 is rotatably connected to the side of the guide rod 201 near the outer wall of the mold body 101 and fits against the outer wall of the support column 203. A cooling fan 205 is connected to the output end of the drive shaft 204. A protective net 206 is sleeved and fixed on the outer wall of the cooling fan 205. A transmission gear 207 is machined on the outer wall of the drive shaft 204.

[0029] The clamping mechanism 3 includes a support plate 301, which is mechanically connected to the bottom end of the support column 203 and slidably connected to the inside of the stamping table 1. A threaded screw 302 is rotatably connected inside the stamping table 1 and passes through the support plate 301 to the inside of the mold body 101. A telescopic slider 303 is sleeved on the outer wall of the threaded screw 302 and slidably connected to the inside of the mold body 101.

[0030] Through the cooperation between the internal parts of the heat dissipation mechanism 2, the heat dissipation fan 205 can be driven to rotate and continuously blow air to dissipate heat on the surface of the mold body 101 during continuous stamping by the stamping head and the mold body 101, thereby reducing the temperature of the mold body 101 during stamping. Through the cooperation between the internal parts of the clamping mechanism 3, the stamped parts placed in the mold body 101 can be clamped and limited to prevent the stamped parts from shifting during the stamping process and causing the stamping quality to be unqualified.

[0031] Refer to the instruction manual appendix Figure 1-5 The clamping mechanism 3 also includes clamping plates 304. There are multiple clamping plates 304, which are slidably connected to both sides of the inner wall of the mold body 101 and located on the top side of the telescopic slider 303. The bottom end of the clamping plate 304 is machined with a limit plate 305. The limit plate 305 is connected and fixed with the inner wall of the mold body 101 by a limit spring 306. Through the mutual cooperation between the internal parts of the clamping mechanism 3, the stamping parts placed in the mold body 101 can be clamped and limited to prevent the stamping quality from being unqualified due to displacement during the stamping process.

[0032] Refer to the instruction manual appendix Figure 1-5 The bottom end of the guide plate 202 is bolted to a punch head, and the top end is connected to a hydraulic cylinder and a hydraulic pump. The guide rod 201 has a connecting groove inside that matches the support column 203. The connecting groove inside the guide rod 201 matches the support column 203, which makes it easy for the guide plate 202 to drive the punch head to move, and simultaneously drive the support column 203 to slide inside the guide rod 201.

[0033] Refer to the instruction manual appendix Figure 1-5 The outer wall of the support column 203 is machined with a rack that matches the transmission gear 207. The transmission shaft 204 and the cooling fan 205 are rotatably connected to the outer wall of the guide rod 201 through bearings. The horizontal height of the cooling fan 205 is the same as the horizontal height of the mold body 101. The support column 203 is machined with a rack that matches the transmission gear 207, which facilitates the movement of the support column 203 to drive the transmission gear 207 to rotate. This, in turn, drives the cooling fan 205 to rotate through the transmission shaft 204 to cool down the heat generated by the stamping on the surface of the mold body 101.

[0034] Refer to the instruction manual appendix Figure 1-5 The support plate 301 and the telescopic slider 303 have internal threads that match the external threads of the threaded screw 302. The threads connecting the top of the threaded screw 302 and the telescopic slider 303 rotate in opposite directions to the threads connecting the bottom of the threaded screw 302 and the support plate 301. The stamping table 1 has a support groove that matches the support plate 301. The mold body 101 has a telescopic groove that matches the telescopic slider 303. The telescopic slider 303 has internal threads that match the external threads of the threaded screw 302. The threads connecting the top of the threaded screw 302 and the telescopic slider 303 rotate in opposite directions to the threads connecting the bottom of the threaded screw 302 and the support plate 301. The stamping table 1 has a support groove that matches the support plate 301. The mold body 101 has a telescopic groove that matches the telescopic slider 303. This allows the support plate 301 to slide inside the stamping table 1, driving the threaded screw 302 to rotate through the threads, and also driving the telescopic slider 303 to extend and slide through the threads.

[0035] Refer to the instruction manual appendix Figure 1-5 The top of the telescopic slider 303 and the bottom of the clamping plate 304 are both machined with matching conical surfaces. The mold body 101 has a limiting groove that matches the limiting plate 305 inside. The surface of the clamping plate 304 that contacts the workpiece is made of rubber. The limiting groove that matches the limiting plate 305 inside the mold body 101 and the surface of the clamping plate 304 that contacts the workpiece is made of rubber, which facilitates the movement of the clamping plate 304 inside the mold body 101 and clamps and limits the two sides of the stamped part surface.

[0036] The working principle of this practical application is as follows:

[0037] Refer to the instruction manual appendix Figure 1-5By placing the stamped part on the mold body 101, the hydraulic cylinder is activated to drive the guide plate 202 to move downward, causing the guide plate 202 to drive the stamping head to move downward to complete the stamping work on the stamped part on the mold body 101. At the same time, the guide plate 202 slides on the outer wall of the guide rod 201, causing the support column 203 to move. The movement of the support column 203 drives the transmission gear 207 to rotate through the rack. The rotation of the transmission gear 207 drives the transmission shaft 204 to rotate. The rotation of the transmission shaft 204 drives the cooling fan 205 to rotate, causing the cooling fan 205 to rotate and blow air to cool the mold body 101. Thus, when the mold body 101 is continuously stamping, the reciprocating movement of the support column 203 drives the cooling fan 205 to continuously rotate and blow air to cool the mold body 101, causing the air near the mold body 101 to flow rapidly, improving the heat dissipation of the mold body 101 itself. At the same time, the rotation of the cooling fan 205 can accelerate the heat dissipation efficiency of the mold.

[0038] Refer to the instruction manual appendix Figure 1-5 The guide plate 202 moves downward, causing the support column 203 to move. The movement of the support column 203 causes the support plate 301 to move synchronously. The movement of the support plate 301 causes the threaded screw 302 to rotate through the thread. The rotation of the threaded screw 302 causes the telescopic slider 303 to slide upward through the thread. The telescopic slider 303 moves upward and presses against the clamping plate 304. The clamping plate 304 is forced to push the limiting plate 305 to compress the limiting spring 306 and move. The clamping plate 304 moves to clamp and limit the stamping part at the top of the mold body 101, preventing the stamping part from shifting during the stamping process and causing the stamping quality to be unqualified.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
