Description

Technical Field

[0001] This invention relates to the field of metal parts processing technology, specifically to a stamping die for metal parts processing. Background Technology

[0002] During the processing of metal parts, stamping dies are used to produce metal parts. Stamping dies are a special process equipment used in cold stamping to process workpieces into parts. They generally consist of a first die base, a punch, a second die base, and a die. The die and punch form a forming cavity, which can improve processing efficiency. They are equipped with a disassembly structure to facilitate the disassembly and assembly of the upper and lower dies, and a cleaning structure to quickly and thoroughly remove the debris generated during processing from the die, avoiding debris residue. For example, Chinese Patent CN117102360B discloses a stamping die for processing mobile phone spring clips, belonging to the field of stamping die technology. This invention includes a first die base, with guide pillars fixedly installed around its lower surface, and a second die base installed at the bottom of the guide pillars; lower pads are fixed around the bottom surface of the second die base; it also includes: an upper pad plate installed on the lower surface of the first die base, with an upper clamping plate fixed to the lower outer side of the upper pad plate, and an upper template installed at the bottom of the upper clamping plate; a lower pad plate fixed on the upper surface of the second die base, with a lower clamping plate fixed to the upper outer side of the lower pad plate. This stamping die for processing mobile phone spring clips is equipped with upper and lower connecting pillars. A bidirectional lead screw drives two clamping plates with threads connected to their outer ends to move outwards, thereby separating the two sets of clamping plates from the upper and lower templates respectively. This facilitates the simultaneous removal of the upper and lower templates from the stamping die for easy replacement, saving time and effort. For example, Chinese patent CN223997109U discloses a chamfering stamping die with a positive pressure blowing structure, including a base. Hydraulic rods are fixedly installed on the upper surfaces of both ends of the base, and a top plate is fixedly connected to the upper end of each hydraulic rod. A lower die is fixedly mounted on the upper surface of the base, and an upper die is fixedly mounted on the lower surface of the top plate. A support column is fixedly mounted on the upper end of the lower die, and a sliding limiting column is installed on the upper end of the support column. One end of a pressure relief groove penetrates the inner surface of the upper end of the lower die, and the other end of the pressure relief groove penetrates the upper surface of the lower die. One end of a pressure hole penetrates the inner surface of the lower end of the support column. This chamfering stamping die with a positive pressure blowing structure, through a pressurizing mechanism, blows air into the interior of the upper end of the lower die before stamping to generate a strong and uniform positive pressure airflow, quickly and thoroughly cleaning the debris generated during chamfering from all directions without dead angles, avoiding debris residue. Based on existing solutions and actual production and processing applications, existing stamping dies for metal parts processing generate debris during the stamping process. While a demolding structure can quickly unload the formed product and a cleaning component can remove the debris, it is not possible to clean the bottom die body simultaneously with rapid unloading, and it is inconvenient to efficiently handle the debris falling from the die. Therefore, we propose a stamping die for metal parts processing to solve the problems mentioned above. Summary of the Invention

[0003] The purpose of this invention is to provide a stamping die for metal parts processing, in order to solve the problem mentioned in the background art that existing stamping dies for metal parts processing generate debris during the stamping process. While a demolding structure is provided to quickly unload the formed product and a cleaning component is provided to remove the debris, it is not possible to clean the bottom die body while quickly unloading the material, and it is inconvenient and inefficient to handle the debris falling from the die.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a stamping die for metal parts processing, comprising a base plate, a bottom die body, and a storage box. A first mold base is fixed above the base plate, and a transmission assembly for splitting the bottom die body is installed on the first mold base. The storage box has sliders installed on both the front and back sides of its bottom. A drawer is installed inside the bottom of the storage box, and a filter frame is provided above the drawer. A small air pump is installed on the right end of the upper surface of the first mold base. A delivery pipe is fixed to the output end of the small air pump. An air blowing pipe is fixed to the left end of the delivery pipe, and the left end of the air blowing pipe is fixed to the first mold base by a rod. A second mold base is provided above the first mold base, and a top mold assembly is installed on the second mold base.

[0005] By adopting the above technical solution, the bottom cavity body can be cleaned while unloading material quickly, and debris falling from the mold can be handled efficiently.

[0006] As a preferred embodiment of the present invention, the transmission assembly includes a motor, a pulley, a transmission belt, a reverse screw, a mounting plate, a turntable, a side plate, a first support plate, a second support plate, a limiting rod, and a support roller. A motor is fixed to the rear of the first mold base via a rod. A pulley is fixed to the output end of the motor. A transmission belt is provided on the outer side of the pulley. A reverse screw is fixed to the front side of the pulley at the motor output end. The reverse screw threadedly drives the mounting plate, and a bottom die body is mounted on the inner side of the mounting plate. A limiting rod passes through the right end of the mounting plate. A side plate is fixed to the left end of the upper surface of the base plate. A support roller is rotatably mounted inside the side plate. A turntable is mounted on the outer end of the support roller. A first support plate is rotatably mounted on the inner end of the turntable, and a second support plate is rotatably mounted on the inner end of the first support plate.

[0007] By adopting the above technical solution, a pulley is fixed at the output end of the motor, a transmission belt is provided on the outside of the pulley, a reverse screw is fixed on the front side of the pulley at the output end of the motor, and a pulley is fixed at the rear end of the support roller. The arrangement of the pulley and the transmission belt enables the motor to drive the reverse screw and the turntable to rotate, and move the storage box left and right while moving the bottom die body back and forth.

[0008] As a preferred embodiment of the present invention, the mounting plate forms a sliding structure with the first mold base via a reverse lead screw.

[0009] By adopting the above technical solution, the mounting plate and the first mold base form a front-to-back sliding structure, and the front and back bottom concave mold bodies are separated and combined by moving the front and back mounting plates.

[0010] As a preferred embodiment of the present invention, the right end of the second support plate is rotatably connected to the storage box.

[0011] By adopting the above technical solution, the second support plate is rotatably connected to the storage box, and the rotation of the second support plate causes the storage box to move left and right.

[0012] As a preferred embodiment of the present invention, the base plate has a groove inside, and the slider is located in the groove of the base plate.

[0013] By adopting the above technical solution, the slider with the convex shape is located in the groove of the base plate. The slider is limited by the groove inside the base plate, so that the storage box can only move left and right, and the slider can be prevented from falling out.

[0014] As a preferred embodiment of the present invention, the filter frame is slidably installed inside the storage box.

[0015] By adopting the above technical solution, the filter frame is slidably installed inside the storage box, making it easy to remove the filter frame from inside the storage box, thereby facilitating the removal of the metal parts formed on the filter frame.

[0016] As a preferred embodiment of the present invention, the top mold assembly includes a first electric telescopic rod, a second electric telescopic rod, a pressure plate, a mounting frame, and a top punch body. The first electric telescopic rod is fixed inside the second mold base, and the second electric telescopic rod is provided on the inner side of the first electric telescopic rod. The pressure plate is fixed to the output end of the first electric telescopic rod, and the mounting frame is fixed to the inner side of the pressure plate. The top punch body is fixed to the output end of the second electric telescopic rod, and the second electric telescopic rod is fixed inside the mounting frame.

[0017] By adopting the above technical solution, a pressure plate is fixed at the output end of the first electric telescopic rod, and a top punch body is fixed at the output end of the second electric telescopic rod. The metal parts are positioned and stamped by moving the pressure plate and the top punch body downward.

[0018] As a preferred embodiment of the present invention, the air blowing pipe is symmetrically arranged about the center line of the top punch body, and the inner end of the air blowing pipe is provided with air outlets at equal intervals.

[0019] By adopting the above technical solution, the inner end of the air blowing pipe is provided with air outlets at equal intervals. The air outlets at equal intervals allow the gas to be blown evenly toward the bottom die body, quickly blowing off the debris on the bottom die body.

[0020] As a preferred embodiment of the present invention, the interior of the second mold base is provided with a hole through which the second electric telescopic rod passes.

[0021] By adopting the above technical solution, the interior of the second mold base is provided with a hole for the second electric telescopic rod to slide up and down. When the first electric telescopic rod drives the second electric telescopic rod to rise and fall, the second electric telescopic rod can move on the second mold base.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the stamping die for metal parts processing, the existing stamping die for metal parts processing, can clean the bottom die body while quickly unloading the material, and can also efficiently handle the debris falling from the die. 1. After stamping the metal parts, the two sets of bottom die bodies are quickly separated by the transmission assembly. The motor drives the pulley and the reverse screw to rotate, thereby moving the mounting plate and the bottom die body outward and separating the two sets of bottom die bodies. This allows for the quick removal of the metal parts from the bottom die bodies. As the bottom die bodies move outward, a small vacuum pump delivers gas to the air blowing pipe through the delivery pipe. The gas is blown from the air outlet of the air blowing pipe towards the bottom die bodies, quickly cleaning the debris on the bottom die bodies. When the bottom die bodies move to the brush of the air blowing pipe, the brush can clean the bottom die bodies, enabling the cleaning of the bottom die bodies while quickly unloading the material. 2. The motor drives the turntable and support roller to rotate through the pulley and transmission belt, thereby rotating the first support plate and the second support plate, causing the storage box, slider, drawer and filter frame to move left and right. The left and right movement of the storage box and filter frame makes the metal parts evenly distributed on the filter frame and can quickly screen out the debris. The debris passes through the filter holes on the filter frame and falls into the inside of the drawer, which is convenient and efficient for handling the debris falling from the mold. The slider with a raised U-shaped structure at the bottom of the storage box is located in the groove of the base plate, which can limit the movement trajectory of the storage box on the base plate. The storage box is relatively large and only moves slightly left and right, so that the storage box can completely accept the falling metal parts. 3. Both the drawer and the filter frame are slidably installed inside the storage box. Pulling the drawer and the filter frame back and forth makes it easy to disassemble and assemble them, thus facilitating the handling of debris inside the drawer and the molded metal parts inside the filter frame.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] In existing stamping dies for metal parts processing, some metal parts will generate debris during the stamping process. A demolding structure is set to quickly unload the formed product, and a cleaning component is set to remove the debris. However, it is not possible to clean the bottom die body 8 at the same time as the rapid unloading, and it is inconvenient to efficiently handle the debris falling from the die.

A first electric telescopic rod 21, a second electric telescopic rod 22, a pressure plate 23, a mounting frame 24, and a top punch body 25 constitute the top die assembly. like Figure 1 As shown, a first mold base 2 is fixed above the base plate 1, and a rod is fixed between the first mold base 2 and the base plate 1. A transmission assembly for splitting the bottom die body 8 is installed on the first mold base 2. like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 9As shown, the transmission assembly includes a motor 3, a pulley 4, a transmission belt 5, a reverse screw 6, a mounting plate 7, a turntable 9, a side plate 10, a first support plate 11, a second support plate 12, a limiting rod 26, and a support roller 27. The motor 3 is fixed to the rear of the first mold base 2 via a rod. A pulley 4 is fixed to the output end of the motor 3, and a transmission belt 5 is provided on the outer side of the pulley 4. A reverse screw 6 is fixed to the front side of the pulley 4 at the output end of the motor 3. The front end of the reverse screw 6 is rotatably mounted on the first mold base 2. The reverse screw 6 is connected to the mounting plate... 7. Threaded connection, reverse screw 6 threaded drive with mounting plate 7, and bottom die body 8 mounted on the inner side of mounting plate 7. Bottom die body 8 can be removed from mounting plate 7. Limiting rod 26 passes through the right end of mounting plate 7. Limiting rod 26 is fixed on the first mold base 2. Side plate 10 is fixed to the left end of the upper surface of base plate 1. Support roller 27 is rotatably mounted inside side plate 10, supporting support roller 27 through side plate 10. Turntable 9 is mounted on the outer end of support roller 27. First support plate 11 is rotatably mounted on the inner end of turntable 9. Figure 9 As shown, the turntable 9 is composed of two sets of discs. The first support plate 11 is eccentrically installed at the inner end of the turntable 9. When the support roller 27 rotates, the turntable 9 rotates with the support roller 27. The rear end of the support roller 27 is fixedly connected to the pulley 4. When the pulley 4 rotates, the support roller 27 rotates. A second support plate 12 is rotatably mounted on the inner end of the first support plate 11. The mounting plate 7 forms a sliding structure with the first mold base 2 via a reverse lead screw 6. The right end of the second support plate 12 is rotatably connected to the storage box 13. A sliding groove is provided inside the base plate 1, and the slider 14 is located in the sliding groove of the base plate 1. Figure 6 As shown, slider 14 has a convex-shaped structure, which can prevent slider 14 from coming out of the groove; The storage box 13 has sliders 14 installed on both the front and back sides of the bottom. The storage box 13 has a drawer 15 installed at the bottom inside. A filter frame 16 is set above the drawer 15 and is slidably installed inside the storage box 13. A small vacuum pump 17 is installed on the right end of the upper surface of the first mold base 2. A conveying pipe 18 is fixed to the output end of the small vacuum pump 17. An air blowing pipe 19 is fixed to the left end of the conveying pipe 18. The left end of the air blowing pipe 19 is fixed to the first mold base 2 by a rod. The distance between the rod at the left end of the air blowing pipe 19 and the left side of the small vacuum pump 17 is greater than the length of the mounting plate 7. The height of the air blowing pipe 19 is higher than the bottom die body 8. Thus, the mounting plate 7 and the bottom die body 8 can move back and forth under the air blowing pipe 19. The mounting plate 7 and the bottom die body 8 will not be blocked by the small vacuum pump 17, the conveying pipe 18 and the air blowing pipe 19. A second mold base 20 is provided above the first mold base 2, and a top mold assembly is installed on the second mold base 20, such as... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the top mold assembly includes a first electric telescopic rod 21, a second electric telescopic rod 22, a pressure plate 23, a mounting frame 24, and a top punch body 25. The first electric telescopic rod 21 is fixed inside the second mold base 20, and the second electric telescopic rod 22 is disposed inside the first electric telescopic rod 21. The pressure plate 23 is fixed to the output end of the first electric telescopic rod 21, and the mounting frame 24 is fixed to the inner side of the pressure plate 23. The top punch body 25 is fixed to the output end of the second electric telescopic rod 22, and the second electric telescopic rod 22 is fixed inside the mounting frame 24. An air blowing pipe 19 is positioned relative to the top punch body 25. The center line of the mold body 25 is symmetrically arranged, and the inner end of the air blowing pipe 19 is provided with air outlets at equal intervals. The air outlets at equal intervals are used to blow the gas evenly to the bottom die body 8, quickly blowing off the debris on the bottom die body 8. The interior of the second mold base 20 is provided with a hole for the second electric telescopic rod 22 to pass through. The metal parts are positioned and stamped by the lower pressure plate 23 and the top punch body 25. A brush is installed at the bottom end of the air blowing pipe 19. When the bottom die body 8 moves to the brush of the air blowing pipe 19, the brush can clean the bottom die body 8. When stamping metal workpieces, the metal workpiece to be processed is placed on the structure where the two sets of bottom die bodies 8 are joined together. The first electric telescopic rod 21 (not shown in the controller figure) is started by the controller. The extension and retraction of the first electric telescopic rod 21 drives the second electric telescopic rod 22, the pressure plate 23, the mounting frame 24 and the top punch body 25 to move downward. The second electric telescopic rod 22 moves downward in the hole of the second die base 20. Next, the controller controls the second electric telescopic rod 22, which drives the top punch body 25 to move downward. The top punch body 25 and the bottom die body 8 combine to form a mold cavity, and the metal workpiece is formed in the mold cavity. Then, the second electric telescopic rod 22 drives the top punch body 25 to rise, so that the top punch body 25 leaves the formed metal workpiece. Then, the front and rear sets of bottom die bodies 8 are separated by the transmission assembly. The motor 3 is started by the controller. The motor 3 drives the reverse screw 6 to rotate clockwise through the pulley 4. The front and rear sets of mounting plates 7, which are threaded to the reverse screw 6, move outward, thereby moving the bottom die body 8 outward. The metal workpiece on the bottom die body 8 passes through the hole in the middle of the first mold base 2 and falls onto the filter frame 16. During the movement of the bottom die body 8, the limit rod 26 limits the movement trajectory of the mounting plate 7 to prevent the mounting plate 7 from rotating. While the two sets of bottom die bodies 8 move outward, the small air pump 17 is activated by the controller. The small air pump 17 draws in outside air, which is then delivered from the conveying pipe 18 to the blowing pipe 19. The air is then blown from the equally spaced air outlets of the blowing pipe 19 toward the bottom die body 8. Debris on the bottom die body 8 falls off and passes through the filter frame 16 into the drawer 15. The bottom die body 8 is cleaned by the small air pump 17, the conveying pipe 18, the blowing pipe 19, and the outward movement of the bottom die body 8. The bottom die body 8 is cleaned quickly. Since the gas blown out from the air outlet of the air pipe 19 blows directly onto the bottom die body 8, the debris will not stick to the reverse screw 6, thus not affecting the reverse screw 6 and the mounting plate 7. When the two sets of bottom die bodies 8 move outward, the motor 3 drives the support roller 27 and turntable 9 to rotate through the pulley 4 and the transmission belt 5. The support roller 27 rotates in the side plate 10, thereby rotating the first support plate 11 and the second support plate 12, and then the storage box 13 moves left and right. The slider 14 moves left and right in the groove of the bottom plate 1, shaking the drawer box 15 and the filter frame 16, so that the debris on the filter frame 16 falls quickly into the drawer box 15. The formed metal workpieces can be distributed as evenly as possible on the filter frame 16, so that the space formed by the filter frame 16 and the storage box 13 can hold more metal parts. When it is necessary to handle debris or metal parts, the staff pulls the drawer 15 and filter frame 16 forward respectively, and pulls the drawer 15 and filter frame 16 out of the storage box 13 to handle the debris in the drawer 15 and the metal parts on the filter frame 16 respectively. All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
