[0002] A stamping die is a special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called a cold stamping die (commonly known as a cold punching die). There are many forms of stamping dies, and stamping dies are also classified according to three aspects: working nature, die structure, and die material.

[0003] The utility model with the authorized publication number of CN217912495U discloses a stamping die with a replaceable stamping die head, including: an upper die and a lower die at the bottom of the upper die. A slot hole is opened on the top surface of the upper die, a screw is connected inside the slot hole, the lower end of the screw is connected with a punch head, a convex block is connected to the top surface of the punch head, and a spring is connected to the surface of the convex block. When using this stamping die with a replaceable stamping die head, first, a screwdriver is used to disassemble the screw in the slot hole on the surface of the upper die, then the screw is completely separated from the cooperation with the punch head. Then, the stressed spring is elastically stressed, which drives the convex block to form an elastic force on the punch head, so that the convex block squeezes the punch head, making the punch head quickly detach from the tight connection with the upper die. Then, the punch head can quickly detach from the groove, achieving the purpose of easy replacement.

[0004] After analysis, it is found that after the stamping operation is completed, workers need to manually take out the workpiece. On the premise of increasing the operation time, there may also be problems such as work injuries due to improper operation during the process of workers taking out the workpiece. Content of the Utility Model

[0005] The purpose of the utility model is to provide a stamping die convenient for blanking to solve the problems raised in the above background.

[0006] To solve the above technical problems, the utility model provides a stamping die convenient for blanking, including a base and a stamping table arranged in the middle of the upper surface of the base. The base is connected with a cylinder through a support frame. The output end of the cylinder is connected with a connecting plate. The lower surface of the connecting plate is connected with a stamping block. The stamping block is located directly above the stamping table. The workpiece is processed in cooperation with the stamping block in the stamping table. The base is hollowly arranged, and a blanking component is arranged in cooperation with the connecting plate. The blanking component includes a slider slidably connected with the base and a pushing block connected to the lower surface of the connecting plate. A blanking port is arranged on the lower surface of the base in cooperation with the stamping table.

[0007] Further, the cross-section of the slider is trapezoidal and there are two sets of them. The cross-section of the push block is triangular and there are two sets of them. The inclined surface of the push block cooperates with the inclined surface of the slider. One side of the slider close to the base is connected to the base through a first return spring.

[0008] Further, a chute is provided on the inner wall of the stamping table, and a stopper is slidably connected to the chute. The stopper is connected to the chute through a second return spring.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0027] like Figures 1 to 9As shown in the figure, the utility model provides a stamping die convenient for blanking, which includes a base 1 and a stamping table 101 arranged in the middle of the upper surface of the base 1. The base 1 is connected with a cylinder 2 through a support frame. The output end of the cylinder 2 is connected with a connecting plate 201. The lower surface of the connecting plate 201 is connected with a stamping block 202. The stamping block 202 is located directly above the stamping table 101. The workpiece 4 is processed in cooperation with the stamping block 202 on the stamping table 101. Specifically, the product to be processed is placed on the stamping table 101, and starting the cylinder 2 can complete the stamping to obtain the processed workpiece 4. The base 1 is hollow, and a blanking component 3 is arranged in cooperation with the connecting plate 201. The blanking component 3 includes a slider 301 slidably connected with the base 1 and a pushing block 302 connected with the lower surface of the connecting plate 201. A blanking port 307 is arranged on the lower surface of the base 1 in cooperation with the stamping table 101. The processed workpiece 4 falls from the blanking port 307. In the actual production process, the staff can place a collection box or the like below the blanking port 307 to centrally collect the workpiece 4. Two groups of transverse positioning plates 102 are arranged in the transverse direction of the stamping table 101, and two groups of longitudinal positioning plates 103 are arranged in the longitudinal direction of the stamping table 101. One end of the longitudinal positioning plate 103 is slidably connected with the stamping table 101 through a lead screw 104, and the other end is slidably connected with the stamping table 101 through a guide rod 105. The transverse positioning plate 102 and the longitudinal positioning plate 103 can simply position the product to be processed. The pushing block 302 is provided with a notch 308 in cooperation with the lead screw 104. The size of the notch 308 can be slightly larger than the size of the lead screw 104 extending to the outer end of the stamping table 101 in the specific design, which is convenient for the up and down movement of the pushing block 302.

[0028] As Figure 1 With Figure 2As shown in the figure, the cross-section of the slider 301 is trapezoidal, and there are two sets of them. The cross-section of the push block 302 is triangular, and there are two sets of them. The inclined surfaces of the push block 302 and the slider 301 cooperate with each other. When the air cylinder 2 pushes the connecting plate 201 downward for stamping, the push blocks 302 will move downward together and push the sliders 301 to move closer to each other. One side of the slider 301 close to the base 1 is connected to the base 1 through a first return spring 303. When the stamping is completed and the connecting plate 201 moves upward, the slider 301 loses the thrust and resets under the action of the first return spring 303. Both sides of the slider 301 are provided with slide rods 309. The base 1 is provided with a guide groove 311 for the slide rod 309. Multiple sets of balls 310 are provided on the contact surfaces between the slide rod 309 and the guide groove 311. The balls 310 are rotatably connected to the slide rod 309. The guide groove 311 is provided with an arc-shaped groove for the balls 310. Since the force for the sliders 301 to move closer to each other is only provided by the downward movement of the push blocks 302, and the pushing is carried out through the inclined surface, a relatively large amount of thrust will be lost. Therefore, the balls 310 and the arc-shaped groove cooperating with the balls 310 are provided to reduce the resistance during the movement of the push blocks 302 and make the movement of the push blocks 302 smoother.

[0029] As Figure 3 with Figure 6 As shown in the figure, a chute 305 is opened on the inner wall of the stamping table 101, and a stop block 304 is slidably connected to the chute 305. The stop block 304 is connected to the chute 305 through a second return spring 306. It should be noted that the upper right part of the end of the stop block 304 close to each other is provided with an arc surface. When the stamping block 202 pushes the workpiece 4 downward, the workpiece 4 will contact and press the arc surface of the stop block 304, forcing the stop block 304 to slide into the chute 305. When the workpiece 4 completely moves to the lower end of the stop block 304, the stop block 304 loses the resistance and pops out under the action of the second return spring 306.

[0030] Specifically, first place the product to be processed on the upper surface of the stamping table 101, and complete the fixation through the lateral positioning plate 102 and the longitudinal positioning plate 103. Start the cylinder 2 to perform stamping. The stamping block 202 stamps the workpiece 4 and drives the workpiece 4 to move downward. During this process, the stop block 304 will first slide inward and then reset. At this time, the push block 302 pushes the slider 301, causing the sliders 301 to approach each other, forming a closed surface at the bottom of the stamping table 101. At this time, the stamping block 202 also drives the workpiece 4 to move to the upper surface of the slider 301. Under the action of the slider 301, the stamping block 202 stamps the workpiece 4 to make the bottom of the workpiece 4 flat, and finally completes the processing of the workpiece 4. After the stamping is completed, the connecting plate 201 moves upward, and the slider 301 starts to reset. At the same time, due to the action of friction, the stamping block 202 drives the workpiece 4 to move upward. During the movement, the workpiece 4 will contact the reset stop block 304, and then fall off from the stamping block 202 and finally fall from the blanking port 307.

[0031] Based on the ideal embodiments of the present invention as inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
