Description

Technical Field

[0001] The invention relates to a field, and in particular to a stamping die with a trimming side-pushing structure. Background Art

[0002] A stamping die is a special process equipment used in cold stamping to process metal materials or non-metal materials into parts or semi-finished products. It is called a cold stamping die. Its working principle is to use a die installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining a pressure processing method for the required parts.

[0003] In the existing processing methods, it is often difficult to form parts with more complex shapes in one go. Multiple mold combinations are required to gradually process the sheets or strips, such as punching and stamping. The stamping process needs to be performed multiple times. During stamping, the product is connected to the edge of the material through the connecting rib. After the product is formed, it is necessary to cut at the connection between the connecting rib and the product. The connecting rib itself has a certain elasticity. After cutting, there is a certain probability that the cut end will hook the product. During the next stamping, the product and the connecting rib are stamped by the mold at the same time, resulting in damage to the product and reducing the qualified rate of the formed products.

[0004] Therefore, it is necessary to develop a stamping die with a trimming side push structure to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a stamping die with a trimming side-pushing structure for improving the product qualification rate.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a stamping die with a trimming side-pushing structure, comprising: an upper die and a lower die docked with the upper die;

[0007] The upper die includes a pressing assembly for fixing the product, a side pushing assembly provided on one side of the pressing assembly, and a trimming punch. The side pushing assembly includes a slider and a punch located at one end of the slider. The punch can push the slider toward the connection between the product and the connecting rib. The slider pushes the connecting rib to move in the opposite direction of the product, causing the connecting rib to deform.

[0008] The lower die is provided with a trimming edge, and the trimming punch moves toward the trimming edge to punch and cut the deformed connecting ribs.

[0009] Furthermore, one end of the slider is located below the inserting punch, and the other end extends horizontally toward the trimming punch.

[0010] Furthermore, the shape of the slider is L-shaped, and one end extending toward the trimming punch extends perpendicularly toward the connection between the product and the connecting rib.

[0011] Furthermore, the side push assembly includes a reset elastic member, one end of which abuts against the upper mold and the other end abuts against the slider, and the reset elastic member can drive the slider back to its original position.

[0012] Furthermore, the length of the trimming punch is greater than that of the insert punch. The insert punch first pushes the slider to push the connecting rib to move in the opposite direction of the product, and then the trimming punch moves vertically downward to cut.

[0013] Furthermore, the pressing assembly includes a pressing material and a limiting sleeve that is sleeved with the pressing material. The bottom diameter of the pressing material is smaller than the inner diameter of the product. The pressing material can extend into the interior of the product, and the outer surface of the pressing material abuts against the inner surface of the product.

[0014] Furthermore, the pressing assembly includes an elastic portion that abuts against the pressing material, one end of the elastic portion abuts against the top of the pressing material, and the other end abuts against the upper mold.

[0015] Furthermore, the number of the sliders is a pair and they are respectively located on both sides of the pressing component.

[0016] Compared with the existing technology, the beneficial effect of the present invention is that: the present invention is a stamping die with a trimming side push structure, which has the characteristics of high product qualification rate. It extends into the interior of the product by pressing the material to fix the product, and the punch moves downward to extrude the slider. The slider moves toward the trimming punch, and its end face pushes the connecting rib to move in the opposite direction of the product, causing the connecting rib to deform. The trimming punch moves vertically downward, and the connection between the connecting rib and the product is cut through the trimming blade, avoiding the connecting rib from hooking with the product and reducing the chance of product damage.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 4 The utility model is a stamping die with a trimming side-pushing structure, which includes an upper die 1 and a lower die 2 docked with the upper die 1.

[0025] Please see Figures 1 to 3 The upper mold 1 includes an upper mold base 11 and an upper clamping plate 12 fixedly mounted on the upper mold base 11. The upper mold base 11 carries the upper clamping plate 12 to keep it in a horizontal state. A contour sleeve 13 is installed in the upper clamping plate 12. The contour sleeve 13 extends vertically downward from the upper clamping plate 12 and is connected to a stop plate 14 and a stripping plate 15 at the end. A distance is maintained between the stop plate 14 and the upper clamping plate 12. The stripping plate 15 is installed on the lower surface of the stop plate 14. Secondly, a spring 16 is provided on the top of the contour sleeve 13. The bottom end of the spring 16 resists the contour sleeve 13, and its top end extends into the upper mold base 11 to resist the upper mold base 11.

[0026] The stripper plate 15 is recessed inward from its lower surface to form a receiving groove 17 .

[0027] The upper die 1 further includes a pressing assembly 18 , a side push assembly 19 located on one side of the pressing assembly 18 , and a trimming punch 110 . The pressing assembly 18 , the side push assembly 19 , and the trimming punch 110 are all disposed in the receiving groove 17 .

[0028] Please see Figure 2The pressing assembly 18 includes a pressing material 181, a limiting sleeve 182 that is sleeved on the pressing material 181, and an elastic part 183 that abuts the pressing material 181. The bottom of the pressing material 181 extends vertically downward to the lower surface of the stripping plate 15. The bottom diameter of the pressing material 181 is smaller than the diameter inside the product, that is, the pressing material 181 can extend into the interior of the product, and the outer surface of the pressing material 181 abuts the inner surface of the product. The shape of the pressing material 181 is changed according to demand. In this embodiment, the end of the pressing material 181 is an arc surface, and the limiting sleeve 182 is fixed in the stripping plate 15 to limit the downward movement of the pressing material 181. One end of the elastic part 183 abuts the top of the pressing material 181, and the other end extends into the stop plate 14 and abuts the stop plate 14. When the upper mold 1 moves toward the lower mold 2, the pressing material 181 extends into the interior of the product and fixes the product. As the upper mold 1 continues to move, the elastic part 183 begins to compress, so that the side push assembly 19 and the trimming punch 110 can move continuously.

[0029] Please see Figure 2 and Figure 3 The side push assembly 19 includes a slider 191, a punch 192 that pushes the slider 191 to move, and a reset elastic member 193 that abuts the slider 191. The slider 191 is installed in the receiving groove 17 and is restricted by the stripper plate 15. One end of the slider 191 is located below the punch 192, and the other end extends horizontally toward the trimming punch 110. Preferably, the slider 191 is L-shaped, and one end extending toward the trimming punch 110 extends vertically toward the connection between the product and the connecting rib. The top of the punch 192 is fixed in the upper splint 12, and the bottom extends vertically downward. 192 can move the extrusion slider 191 downward, and the slider 191 moves toward the trimming punch 110. In this embodiment, the number of sliders 191 is a pair and they are respectively located on both sides of the pressing component 18. When the slider 191 moves toward the trimming punch 110, its end face pushes the connecting rib to move in the opposite direction of the product, causing the connecting rib to deform, and the connection between the connecting rib and the product forms a relatively tight state. One end of the reset elastic member 193 abuts the upper mold 1, and the other end abuts the slider 191. The reset elastic member 193 can drive the slider 191 to return to its original position.

[0030] The top of the trimming punch 110 is fixed in the upper clamping plate 12, and the bottom extends vertically downward. The bottom end of the trimming punch 110 can cooperate with the lower die 2 to cut the connection between the connecting rib and the product. Secondly, the length of the trimming punch 110 is greater than the length of the insert punch 192. The insert punch 192 first pushes the slider 191 to push the connecting rib to move in the opposite direction of the product, and then the trimming punch 110 moves vertically downward to cut.

[0031] Please see Figure 4The lower die 2 includes a lower die base 21 and a lower template 22 fixedly mounted on the lower die base 21. The lower die base 21 carries the lower template 22 to keep it in a horizontal state. The lower template 22 is recessed inward from its upper surface to form a trimming edge 23. The trimming punch 110 can extend vertically downward into the trimming edge 23. The trimming punch 110 cuts the connection between the connecting rib and the product through the trimming edge 23.

[0032] When the stamping die with a trimming side-pushing structure of the present invention is used, the product enters the predetermined position through the material strip, the upper die 1 moves toward the lower die 2, the pressing material 181 extends into the interior of the product to fix the product, the insert punch 192 moves downward to extrude the slider 191, and the slider 191 moves toward the trimming punch 110, and its end face pushes the connecting rib to move in the opposite direction of the product, causing the connecting rib to deform, and the connection between the connecting rib and the product forms a relatively taut state, and the trimming punch 110 moves vertically downward to cut the connection between the connecting rib and the product through the trimming blade 23.

[0033] The utility model is a stamping die with a trimming side-pushing structure, which has the characteristics of a high product qualification rate. The die is inserted into the product through the pressing material to fix the product, and the punch moves downward to extrude the slider. The slider moves toward the trimming punch, and its end face pushes the connecting rib to move in the opposite direction of the product, causing the connecting rib to deform. The trimming punch moves vertically downward, and the connection between the connecting rib and the product is cut through the trimming blade, so as to avoid the connecting rib being hooked with the product and reduce the chance of product damage.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
