[0002] In the production of stamping dies, side punching contents at various complex positions on the product surface are often encountered. According to the requirements of stamping production and design, the selection of the side punching method and angle should be carried out strictly in accordance with the requirements. For side punching at special positions of some products, traditional hoisting inclined wedge mechanisms or direct-mounted inclined wedge mechanisms are used. However, the inclined wedge structure generally occupies more space. If traditional hoisting inclined wedge mechanisms or direct-mounted inclined wedge mechanisms are adopted, it is difficult to achieve in a die with relatively limited space, and the area of the die needs to be increased. Moreover, the debugging time of the hoisting inclined wedge mechanism or the direct-mounted inclined wedge mechanism is too long, which will affect the production efficiency. Therefore, there is an urgent need for an inclined wedge mechanism to solve the above problems. Summary of the Utility Model

[0020] In one embodiment of the present utility model, with reference to Figures 1 to 2As shown in the figure, a reverse punching and trimming wedge mechanism in a limited space is provided, which includes an upper die base 100, a lower die base 200, and a driving device. The upper die base 100 is arranged above the lower die base 200, and the driving end of the driving device is connected to the upper die base 100 for driving the upper die base 100 to approach or move away from the lower die base 200. A reverse slider 110 is arranged below the upper die base 100, and the reverse slider 110 is slidably arranged on the upper die base 100 in the horizontal direction. An inserting knife 210 and a lower template 220 are arranged above the lower die base 200. The inserting knife 210 and the lower template 220 are respectively arranged at two ends of the lower die base 200. A slope 211 is arranged on one side of the inserting knife 210 close to the lower template 220, and the slope 211 slopes downward in the direction of the lower template 220. An elastic member 120 is further arranged on the upper die base 100. Two ends of the elastic member 120 respectively abut against the reverse slider 110 and the upper die base 100. The elastic member 120 drives the reverse slider 110 to slide towards the inserting knife 210. A landslide 111 corresponding to the slope 211 is arranged at one end of the reverse slider 110 close to the inserting knife 210. A punching assembly 300 corresponding to the lower template 220 is arranged at one end of the upper die base 100 close to the lower template 220. In this embodiment, a product with specific properties is placed on the corresponding lower template 220, and the driving device drives the upper die base 100 to move towards the lower die base 200. During this process, the landslide 111 of the reverse slider 110 and the slope 211 on the inserting knife 210 slide relative to each other, driving the reverse slider 110 to slide on the upper die base 100 towards the lower template 220, and at the same time compressing the elastic member 120. The elastic member 120 stores elastic potential energy. At this time, the upper die base 100 drives the reverse slider 110 to move downward, and the inserting knife 210 drives the reverse slider 110 to move towards the lower template 220. Then the punching assembly 300 inclines towards the lower template 220 and keeps a perpendicular relationship with the lower template 220, punching and trimming the product on the lower template 220. Subsequently, the driving device drives the upper die base 100 to move away from the lower die base 200. At this time, the elastic potential energy of the elastic member 120 is released, and the reverse slider 110 resets. Using the reverse punching and trimming wedge mechanism in a limited space provided by the present utility model to perform side punching on the product, on the basis of the traditional hoisting wedge, according to the specificity of the product, the working part and the guiding part of the wedge are respectively designed, and then an integrated mechanism with reverse guiding is formed through the connection bridge method. While effectively avoiding the product during the production sliding process, there is sufficient power source, effectively reducing the mold manufacturing cost, effectively reducing the mold debugging time, and better ensuring the shape tolerance of the product hole position in the same set of molds, thereby improving the qualified rate and output.

[0021] Specifically, referring to Figures 1 to 2As shown in the figure, the lower template 220 includes a fastening portion 221, a placement portion 222, a stamping portion 223, and an extension portion 224. The placement portion 222 is used to place the positioning product. The two ends of the placement portion 222 are respectively connected to the fastening portion 221 and the stamping portion 223. The stamping portion 223 cooperates with the stamping assembly 300. The fastening portion 221 is used to fasten the product. The extension portion 224 is arranged on one side of the stamping portion 223 and is used to stabilize the product. A die insert 225 is provided on the stamping portion 223, and the die insert 225 is used to clear the stamping assembly 300. In this embodiment, a product with a specific shape is placed on the placement portion 222. The stamping portion 223 abuts against the side punching surface of the product that needs to be stamped. Both the placement portion 222 and the extension portion 224 are used to stabilize the product. The fastening portion 221 is used to position the product. A die insert 225 is provided on the stamping portion 223 to clear the stamping assembly 300, facilitating the stamping assembly 300 to stamp the product.

[0022] Specifically, referring to Figures 1 to 2 As shown in the figure, the stamping assembly 300 includes a punch backing plate 310, a clamping plate 320, and a punch 330. The punch backing plate 310 is arranged on the reverse slider 110, and the punch backing plate 310 is parallel to the stamping portion 223. The clamping plate 320 is arranged on the punch backing plate 310 and is used to clamp the punch 330. The punch 330 is perpendicular to the punch backing plate 310 and is on the same straight line as the die insert 225. In this embodiment, the clamping plate 320 is used to clamp the punch 330. One end of the punch backing plate 310 abuts against the punch 330, which is used to position the punch 330 and protect the reverse slider 110 when the punch 330 stamps the product, preventing the punch 330 from damaging the reverse slider 110.

[0023] More specifically, referring to Figures 1 to 2 As shown in the figure, the lower template 220 is detachably arranged on the lower die base 200, and the connection method is screw connection. The punch 330 is detachably arranged on the clamping plate 320, and the connection method is that the clamping plate 320 clamps the punch 330. When different products need to be processed, different punches 330 and lower templates 220 are replaced to correspond to different products, enabling the reverse punching and trimming wedge mechanism in a limited space provided by the present utility model to adapt to more side punching of products.

[0024] Specifically, referring to Figures 1 to 2As shown in the figure, the stamping assembly 300 further includes an elastic reset member 340 and a stripper plate 350. The stripper plate 350 is provided with a clearance hole 351 for clearance of the punch 330. The punch 330 passes through the clearance hole 351 and is arranged inside the stripper plate 350, and the stripper plate 350 is parallel to the punch backing plate 310. The two ends of the elastic reset member 340 are respectively connected to the clamping plate 320 and the stripper plate 350. In this embodiment, the stripper plate 350 drives the product and the punch 330 to strip, avoiding the product sticking to the punch 330. After the punch 330 punches the product on the lower template 220, the punch 330 resets. At this time, under the action of the reset elastic member 120, the stripper plate 350 abuts against the product during the reset process of the punch 330, so that the product is separated from the punch 330. Subsequently, after the elastic potential energy of the reset elastic member 120 is released, the stripper plate 350 is separated from the product, so that the product is on the lower template 220, which is convenient for the operator to load and unload, and improves the passing rate and efficiency of product punching.

[0027] Specifically, referring to Figures 1 to 2 As shown in the figure, an inductor 600 is further provided on the upper die base 100. The inductor 600 is arranged at one end of the upper die base 100 away from the elastic member 120 and faces the reverse slider 110.
