Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die that can adapt to irregularly shaped support plates. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). 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 plastically deform, thereby obtaining the desired parts.

[0003] Currently, irregularly shaped workpieces often require stamping dies for processing during production, such as clamping workpieces. Although there are various types of existing stamping dies, they generally suffer from the following problems: the stamping die does not have a workpiece ejection mechanism, making it time-consuming and laborious to demold the stamped irregularly shaped parts. Furthermore, manual operation is still required when unloading the material, which affects the processing efficiency of irregularly shaped parts and results in low safety performance. Therefore, it is urgent to design a stamping die that can adapt to irregularly shaped support plates to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies by proposing a stamping die that can adapt to irregularly shaped support plates. Its advantage lies in the ability to slide the irregularly shaped support plate out of the entire stamping die, enabling the entire stamping die to be equipped with an ejection mechanism specifically for irregularly shaped support plates, facilitating material removal and improving safety performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stamping die adaptable to irregularly shaped support plates includes a U-shaped base and a top base. The top of the U-shaped base and the bottom of the top base are provided with support and reset components. A lower die is fixedly installed on the bottom of the inner wall of the U-shaped base. A pad and an upper die are sequentially installed on the bottom of the top base. Demolding components are provided at both ends of the bottom of the upper die and both ends of the top of the lower die. An ejection component is provided at the middle position of the lower die.

[0007] The above technical solutions enable the entire stamping die to be equipped with an ejection mechanism for irregularly shaped support plates, facilitating material removal and improving safety performance.

[0008] The present invention is further configured such that the demolding assembly includes multiple grooves formed at both ends of the bottom of the upper mold and both ends of the top of the lower mold, and each groove has a lifting frame inserted into its inner wall. Each lifting frame has a sliding roller rotatably connected to its inner wall. The diameter of the sliding roller is smaller than the width of the groove. The bottom of the lifting frame and the inner wall of the groove are fixedly installed with second springs that are evenly distributed.

[0009] The above technical solutions achieve rapid demolding, facilitate subsequent material output, and reduce friction during the stamping process under the action of the sliding rollers, enabling the irregularly shaped support plate to perform deformation operations better.

[0010] The present invention is further configured such that the ejection assembly includes an L-shaped groove opened at the middle position of the top of the lower mold, and an ejection plate and an extrusion plate are movably arranged on the inner wall of the L-shaped groove. The top end of the extrusion plate and the bottom end of the ejection plate are both designed as inclined surfaces. A traction groove is opened at the bottom inclined surface of the ejection plate. A slide block is fixedly arranged in the traction groove at the top inclined surface of the extrusion plate. The cross-section of the slide block and the cross-section of the traction groove are both designed as T-shaped. An electric push rod for adjusting the position of the extrusion plate is fixedly installed on one side of the outer wall of the lower mold. The top surface of the ejection plate is designed as inclined.

[0011] The present invention is further configured such that the top mold of the ejector plate has a first mounting groove that is evenly distributed, and the inner wall of the first mounting groove is rotatably connected to a pulley.

[0012] The above technical solutions enable the irregularly shaped support plate to slide out from the entire stamping die.

[0013] The present invention is further configured such that clamping components are provided on the top of the inner walls at both ends of the U-shaped seat, and the clamping components are used to clamp the workpiece body, which is placed on the top of the lower mold.

[0014] The present invention is further configured such that the clamping assembly includes connecting grooves formed on the top of the inner walls at both ends of the U-shaped seat, and clamping plates are inserted into the inner walls of the connecting grooves. Third springs are fixedly installed at equal intervals on one side of the clamping plates and one side of the connecting grooves.

[0015] The above technical solutions enable the positioning of the workpiece body and facilitate the centering operation of the workpiece body.

[0016] The present invention is further configured such that the support and reset assembly includes guide holes opened at the four corners of the top of the U-shaped seat, and guide posts inserted into the guide holes are fixed at the four corners of the bottom of the top seat. First springs sleeved on the outer wall of the guide posts are fixed at the four corners of the bottom of the top seat and the four corners of the top of the U-shaped seat.

[0017] The above technical solutions facilitate the reset of the upper mold, making subsequent stamping operations easier.

[0018] The present invention is further configured such that a second mounting groove is provided at the top center of the top seat, and a mold handle is fixedly mounted on the inner wall of the second mounting groove.

[0019] The above technical solution connects the die handle to the hydraulic cylinder, making it easier to drive the entire stamping die.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model, through the setting of a lower mold and an upper mold, designs the top surface of the lower mold and the bottom surface of the upper mold to be adapted to the mold structure of the irregular support plate. The upper mold is lowered by applying pressure with a hydraulic cylinder. The irregular support plate is stamped and formed by the cooperation of the upper mold and the lower mold. After the forming is completed, the irregular support plate is separated from the lower mold and the upper mold by the demolding component, achieving the effect of rapid demolding and facilitating subsequent material discharge.

[0022] 2. In this utility model, the ejection assembly allows the electric push rod inside the ejection assembly to adjust the position of the extrusion plate after demolding, thereby extruding the ejection plate and pulley upwards and pushing the irregular support plate to gradually tilt, so that the irregular support plate can slide out of the entire stamping die and onto the electric push rod. This provides the entire stamping die with an ejection mechanism for the irregular support plate, facilitating material removal and improving safety performance. Attached Figure Description

[0033] Reference Figure 1-5A stamping die adaptable to irregularly shaped support plates includes a U-shaped base 1 and a top base 8. Support and reset components are provided at the top of the U-shaped base 1 and the bottom of the top base 8. A second mounting groove is formed at the middle of the top of the top base 8, and a die shank 10 is fixedly mounted on the inner wall of the second mounting groove. A lower die 2 is fixedly mounted on the bottom of the inner wall of the U-shaped base 1. A pad 9 and an upper die 11 are sequentially mounted on the bottom of the top base 8. The top surface of the lower die 2 and the bottom surface of the upper die 11 are designed to adapt to the irregularly shaped support plate. The irregularly shaped support plate is stamped and formed through the cooperation of the upper die 11 and the lower die 2. Demolding components are provided at both ends of the bottom of the upper mold 11 and both ends of the top of the lower mold 2. Each demolding component includes multiple grooves 13 formed at both ends of the bottom of the upper mold 11 and both ends of the top of the lower mold 2. A lifting frame 4 is inserted into the inner wall of each groove 13, and a sliding roller 12 is rotatably connected to the inner wall of each lifting frame 4. The diameter of the sliding roller 12 is smaller than the width of the groove 13. Second springs 14, evenly distributed, are fixedly installed at the bottom of the lifting frame 4 and the inner wall of the groove 13. The demolding components detach the irregularly shaped support plate from the lower mold 2 and the upper mold 11, achieving rapid demolding and facilitating subsequent material discharge. The lower mold 2 is positioned at the middle... The lower mold 2 includes an ejector assembly 3, which comprises an L-shaped groove 302 located at the center of the top of the lower mold 2. An ejector plate 303 and an extrusion plate 306 are movably mounted on the inner wall of the L-shaped groove 302. The top of one end of the extrusion plate 306 and the bottom of one end of the ejector plate 303 are both designed as bevels. A traction groove 305 is provided on the beveled bottom of one end of the ejector plate 303. A slide block is fixedly mounted on the beveled top of one end of the extrusion plate 306 and slidably disposed within the traction groove 305. The cross-section of the slide block and the cross-section of the traction groove 305 are both designed as T-shapes. An adjustment mechanism is fixedly installed on one side of the outer wall of the lower mold 2. The electric push rod 301 at the position of the extrusion plate 306 and the top surface of the ejector plate 303 are designed to be inclined. The top mold of the ejector plate 303 has first mounting grooves distributed at equal intervals, and the inner wall of each first mounting groove is rotatably connected to a pulley 304. The position of the extrusion plate 306 is adjusted by the electric push rod 301 in the ejector assembly 3, and the extrusion plate 303 and pulley 304 are extruded and raised, pushing the irregular support plate to gradually tilt, so that the irregular support plate can slide out from the entire stamping die. This makes the entire stamping die equipped with an ejection mechanism for the irregular support plate, which facilitates material removal and improves safety performance.

[0034] In order to position the workpiece body 16, refer to Figures 1-4The top of the inner walls at both ends of the U-shaped base 1 is provided with a clamping component 5, which is used to clamp the workpiece body 16. The workpiece body 16 is placed on the top of the lower mold 2. The clamping component 5 includes a connecting groove 501 opened on the top of the inner walls at both ends of the U-shaped base 1, and a clamping plate 503 is inserted into the inner wall of the connecting groove 501. A third spring 502 is fixedly installed at equal distances on one side of the clamping plate 503 and one side of the connecting groove 501. The workpiece body 16 is clamped in the mold by the clamping component 5, which facilitates the positioning of the workpiece body 16 and the centering operation of the workpiece body 16.

[0035] In order to reset the upper mold 11, refer to... Figures 1-4 The support reset assembly includes guide holes 15 at the four corners of the top of the U-shaped seat 1, and guide posts 6 inserted into the guide holes 15 are fixed at the four corners of the bottom of the top seat 8. A first spring 7 sleeved on the outer wall of the guide post 6 is fixed at the four corners of the bottom of the top seat 8 and the four corners of the top of the U-shaped seat 1. The reset function of the first spring 7 facilitates the reset of the upper mold 11, which is convenient for subsequent stamping operations.

[0036] Working principle: The die handle 10 is connected to the hydraulic cylinder, and the workpiece body 16 is placed on the lower die 2. The workpiece body 16 is centered by the two clamping plates 503 and the third spring 502 in the clamping assembly 5. Then, the height of the upper die 11 is lowered by the pressure of the hydraulic cylinder. The upper die 11 and the lower die 2 cooperate to perform the stamping and forming operation of the irregular support plate. At this time, the sliding roller 12 and the lifting frame 4 in the demolding assembly will move into the groove 13. After the forming is completed, the hydraulic cylinder is reset, so that the upper die 11 is under the action of the first spring 7. The lower reset mechanism, through the reset action of the second spring 14 in the demolding assembly, disengages the irregular support plate from the lower mold 2 and the upper mold 11, achieving rapid demolding. After demolding, the position of the extrusion plate 306 is adjusted by the electric push rod 301 in the ejection assembly 3, which extrudes the ejection plate 303 and the pulley 304, pushing the irregular support plate to gradually tilt, so that the irregular support plate can slide out of the entire stamping die and onto the electric push rod 301. This ensures that the entire stamping die is equipped with an ejection mechanism for the irregular support plate, facilitating material removal.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
