Description

Technical Field

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

[0002] Stamping dies, also known as punch dies, hardware dies, or metal 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 widely used in various industrial sectors such as automobiles, aerospace, electronics, home appliances, instruments, and toys to produce metal parts with complex shapes and high precision requirements.

[0003] In existing metal sheet stamping processes, the workpiece must be manually placed at the stamping position. This manual placement not only increases the labor intensity of the operators but, more importantly, makes it difficult to ensure consistent placement accuracy each time. Furthermore, manual operation poses safety hazards, as operators must work under the stamping die. In addition, manual placement cannot be precisely coordinated with the stamping action. When the stamping speed increases, it becomes difficult for the operator to keep up with the machine's pace, further limiting the performance of the stamping equipment and preventing high-speed continuous stamping.

[0004] For example, the continuous stamping die feeding mechanism disclosed in CN221184458U includes a stamping machine base, a limit mechanism on the upper surface of the stamping machine base, and a feeding clamping mechanism on the upper surface of the stamping machine base. Although this patent achieves automated feeding of metal sheets by using the feeding clamping mechanism, replacing manual placement and reducing the labor intensity of operators and improving feeding efficiency to a certain extent, its feeding mechanism relies on an independent transmission to drive the threaded rod to achieve feeding, requiring an additional power source, increasing the energy consumption and cost of the equipment. Moreover, the synchronization between the feeding action and the stamping action is difficult to control precisely, and feeding may be delayed or advanced, causing the sheet to be misaligned during stamping and affecting the processing accuracy.

[0005] Therefore, it is necessary to invent a stamping die for processing metal sheets to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a stamping die for metal sheet processing, which solves the problems of needing an additional power source to replace manual feeding, increasing the energy consumption and cost of the equipment, and making it difficult to accurately control the synchronization between the feeding action and the stamping action, which easily leads to feeding delay or advance, causing the sheet to shift in position during stamping and affecting the processing accuracy.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for processing metal sheets, comprising a base, four guide pillars above the base, a top plate fixedly connected to the top of the guide pillars, a hydraulic cylinder mounted on the top surface of the top plate, the output end of the hydraulic cylinder penetrating the top plate and connected to the top surface of a lifting plate, a stamping die head at the center of the bottom surface of the lifting plate, a base directly above the base, a base frame for placing metal sheets on the top surface of the base, a support plate on the side wall of the lifting plate, and a pulling mechanism connected below the support plate via a linkage mechanism. The linkage mechanism drives the pulling mechanism to move as the lifting plate moves up and down, thereby achieving stamping while simultaneously feeding the metal sheet.

[0008] Preferably, the lifting plate is slidably mounted on four guide columns via linear bearings.

[0009] Preferably, a die holder is provided on the base at the position corresponding to the stamping die head, and the die holder has a die hole that matches the stamping die head, and the die hole extends vertically through to the bottom of the base.

[0010] Preferably, a feeding plate is inclinedly arranged directly below the mold hole of the base, and the bottom end of the feeding plate extends to the outside of the base.

[0011] Preferably, the base material frame is symmetrically arranged at the front and rear ends of the top surface of the base, and has a groove inside that is adapted to the metal plate. Multiple equally spaced rollers are rotatably installed in the groove through bearings, and the top surface of the rollers is flush with the top surface of the base.

[0012] Preferably, the linkage mechanism includes a connecting rod and a connecting arm. The upper end of the connecting rod is hinged to the side wall of the support plate, and a strip groove is provided at the lower part. One end of the connecting arm is provided with a roller that is slidably embedded in the strip groove, and the middle part is hinged to the side wall of the base through a fixing plate.

[0013] Preferably, the material pulling mechanism includes a material pulling arm hinged to the end of the connecting arm, the end of the material pulling arm away from the connecting arm is provided with a hook adapted to the metal plate, and a return spring is provided between the material pulling arm and the connecting arm.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model achieves simultaneous stamping and feeding by linking the linkage mechanism with the lifting plate and the material pulling mechanism. When the hydraulic cylinder drives the lifting plate to descend for stamping, the support plate drives the connecting rod to move down. Through the cooperation of the strip groove and the roller, the connecting arm is pushed to rotate around the fixed plate, so that the hook of the material pulling mechanism pulls the metal plate for feeding. When the lifting plate rises and resets, the linkage mechanism moves in the opposite direction, and the hook is reset under the action of the reset spring. Continuous feeding can be completed without an additional power source, which greatly improves the continuity and efficiency of stamping. 2. This utility model ensures the stability of metal sheet feeding by using a roller design within the base frame in conjunction with a feeding mechanism. The roller reduces friction between the sheet and the base frame, making feeding smoother. At the same time, the precise fit between the die holder and the stamping die head, along with the inclined design of the blanking plate, ensures that the stamped workpiece is quickly discharged, improving processing accuracy and automation.

[0017] 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.

[0018] This utility model provides, for example Figure 1-5 The present invention provides a stamping die for processing metal sheet metal parts. To achieve the above-mentioned objective, the present invention provides the following technical solution: A stamping die for processing metal sheet metal parts includes a base 1, four guide pillars 2 are provided above the base 1, a top plate 3 is fixedly connected to the top of the guide pillars 2, a hydraulic cylinder 4 is installed on the top surface of the top plate 3, the output end of the hydraulic cylinder 4 passes through the top plate 3 and is connected to the top surface of the lifting plate 5, the lifting plate 5 is slidably sleeved on the four guide pillars 2 through linear bearings, a stamping die head 6 is provided at the center of the bottom surface of the lifting plate 5, a base 7 is provided directly above the base 1, a base frame 8 for placing metal sheet metal parts is provided on the top surface of the base 7, a support plate 10 is provided on the side wall of the lifting plate 5, and a pulling mechanism 12 is connected below the support plate 10 through a linkage mechanism 11. The linkage mechanism 11 drives the pulling mechanism 12 to move as the lifting plate 5 moves up and down, thereby realizing stamping while simultaneously feeding the metal sheet metal parts.

[0019] A die holder 9 is provided on the base 7 at the position corresponding to the stamping die head 6. The die holder 9 has a die hole that matches the stamping die head 6 and the die hole extends vertically through to the bottom of the base 7. A blanking plate 13 is inclinedly provided directly below the die hole of the base 7 and the bottom end of the blanking plate 13 extends to the outside of the base 1.

[0020] In this embodiment, the die base 9 is used to receive the stamping action of the stamping die head 6. The die hole provides the necessary space and guidance for the stamping process. The waste material or finished product after stamping can fall through the vertically penetrating die hole. The feed plate 13 is inclined and extends to the outside of the base 1, which facilitates guiding the falling material to the outside of the equipment for easy collection and processing, ensuring the continuity and cleanliness of the production process.

[0021] The base frame 8 is symmetrically arranged at the front and rear ends of the top surface of the base 7. The interior is provided with a groove 801 that is compatible with the metal plate. Multiple rollers 802 are equidistantly distributed in the groove 801 and are rotatably installed in the groove 801 through bearings. The top surface of the rollers 802 is flush with the top surface of the base 7.

[0022] In this embodiment, the base frame 8 is used to place the metal sheet to be processed. The groove 801 is adapted to the metal sheet and can position and limit the metal sheet, preventing it from shifting during placement and movement. Multiple equidistant rollers 802 installed in the groove 801 rotate via bearings. When the metal sheet moves on the base 7, the rollers 802 reduce the friction between the metal sheet and the base frame 8, making the metal sheet move more smoothly and improving production efficiency.

[0023] The linkage mechanism 11 includes a connecting rod 1101 and a connecting arm 1103. The upper end of the connecting rod 1101 is hinged to the side wall of the support plate 10, and a strip groove 1102 is provided at the lower part. One end of the connecting arm 1103 is provided with a roller 1104 that slides into the strip groove 1102, and the middle part is hinged to the side wall of the base 7 through a fixing plate 1105. The material pulling mechanism 12 includes a material pulling arm 1201 hinged to the end of the connecting arm 1103. The end of the material pulling arm 1201 away from the connecting arm 1103 is provided with a hook 1202 adapted to the metal plate, and a return spring 1203 is provided between the material pulling arm 1201 and the connecting arm 1103.

[0024] In this embodiment, when the lifting plate 5 drives the stamping die head 6 to rise and fall, it can drive the support plate 10 to rise and fall synchronously, so that the movement of the connecting rod 1101 can be converted into the swing of the connecting arm 1103. This realizes the transmission and conversion of the movement of the support plate 10 into the specific movement of the connecting arm 1103, providing power and movement form conversion for the subsequent action of the pulling mechanism 12. When the connecting arm 1103 swings, it can drive the pulling arm 1201 to move. The hook 1202 adapted to the metal plate is provided at one end of the pulling arm 1201 for gripping and fixing the metal plate. Through the cooperation of the hook 1202 and the metal plate, the metal plate is pulled and positioned according to the production requirements. The return spring 1203 provided between the pulling arm 1201 and the connecting arm 1103 can automatically reset the pulling arm 1201 to the initial position after the pulling arm 1201 completes the pulling action, so as to perform the next pulling operation, ensuring that the pulling mechanism 12 can work continuously and stably, and improving the automation level and production efficiency of production.

[0025] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-5 When using this utility model, firstly, place the metal sheet to be processed in the base frame 8 on the top surface of the base 7, start the hydraulic cylinder 4 installed on the top surface of the top plate 3, the output end of the hydraulic cylinder 4 passes through the top plate 3 and pushes the lifting plate 5 downward. As the lifting plate 5 descends, the stamping die 6 set at the center of its bottom surface also moves downward. When the stamping die 6 approaches the die base 9 set at the corresponding position on the base 7, the stamping operation on the metal sheet placed in the base frame 8 and positioned begins. As the lifting plate 5 descends, the support plate 10 on its side wall also descends synchronously. Since the upper end of the connecting rod 1101 in the linkage mechanism 11 is hinged to the side wall of the support plate 10, the descent of the support plate 10 will drive the connecting rod 1101 to move downward. Therefore, the downward movement of the connecting rod 1101 will cause the roller 1104 to slide in the strip groove 1102, thereby converting the linear motion of the connecting rod 1101 into the swinging of the connecting arm 1103 around its central hinge point. When the connecting arm 1103 swings, it will drive the pulling arm 1201 to move. The end of the pulling arm 1201 away from the connecting arm 1103 is provided with a hook 1202 adapted to the metal plate. The hook 1202 will grab the metal plate. After the sheet metal is stamped, the punching process is completed, and the sheet metal is pulled a certain distance to feed it, preparing it for the next stamping. After the stamping die head 6 completes the stamping of the sheet metal, the output end of the hydraulic cylinder 4 begins to retract, driving the lifting plate 5 to move upward in a straight line along the guide post 2. At this time, the support plate 10 also rises synchronously with the lifting plate 5, and the connecting rod 1101 moves upward accordingly. Through the action of the strip groove 1102 and the roller 1104, the connecting arm 1103 swings in the opposite direction. During the reverse swing of the connecting arm 1103, the elastic force of the return spring 1203 will cause the pulling arm 1201 to automatically reset and return to the initial position so as to perform the next pulling operation. Waste or finished products generated during the stamping process will fall through the die hole that extends vertically from the die base 9 to the bottom of the base 7. A feed plate 13 is inclinedly arranged directly below the die hole of the base 7, and the bottom end of the feed plate 13 extends to the outside of the base 1. The falling waste or finished products will slide down along the inclined feed plate 13 to the outside of the equipment, which is convenient for collection and treatment, and ensures the continuity and cleanliness of the production process.
