Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die material support and positioning structure. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. Stamping dies are also called cold stamping dies. Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or undergo plastic deformation, thereby obtaining the desired parts.

[0003] Existing stamping dies typically use simple locating pins or fixed blocks for material positioning, which has low positioning accuracy. Furthermore, locating pins or fixed blocks cannot accurately position multiple edges and corners of the material, which can easily lead to material displacement or misalignment during the stamping process. Utility Model Content

[0004] The purpose of this invention is to provide a material positioning structure for stamping dies, which facilitates the positioning of materials and solves the problem of inconvenient material positioning in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stamping die material support and positioning structure includes a base, a lower die fixedly connected to the upper end of the base, multiple plates fixedly connected in a rectangular array at the upper end of the base, each plate having a slot at its upper end and a sliding groove on its side wall, a movable block slidably connected inside the sliding groove, a through slot in the movable block, and a positioning groove on its side wall; and an upper seat located on the upper end of the base, a movable plate slidably connected to the lower end of the upper seat, an upper die fixedly connected to the lower end of the movable plate, and multiple push rods fixedly connected in a rectangular array at the lower end of the movable plate.

[0007] Preferably, a torsion spring is fixedly connected to the inner wall of the slide groove, and one end of the torsion spring is fixedly connected to the side wall of the movable block.

[0008] Preferably, a plurality of support rods are fixedly connected to the upper end of the base, and the plurality of support rods are distributed in a rectangular array, with the upper end of the support rods fixedly connected to the lower end of the upper base.

[0009] Preferably, a hydraulic cylinder is fixedly connected to the upper end of the upper seat, and the output end of the hydraulic cylinder is fixedly connected to the upper end of the movable plate.

[0010] Preferably, the upper end of the upper seat has two guide rods that slide through it, and the lower end of the guide rods is fixedly connected to the upper end of the movable plate.

[0011] Preferably, a plurality of torsion springs are fixedly connected to the lower end of the movable plate, and the plurality of torsion springs are distributed in a rectangular array. The torsion springs are sleeved on the outside of the top rod, and a ring plate is slidably connected to the side wall of the top rod. The ends of the torsion springs are fixedly connected to the upper end of the ring plate.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. When stamping materials, the four corners of the rectangular material are placed inside the positioning slots on the side walls of the four movable blocks. The material is positioned by multiple positioning slots. The ejector rod slides through the slot into the slot opening. The inclined wall of the ejector rod contacts the inclined inner wall of the slot opening, causing the movable block to slide into the slide groove. Once the torsion spring is compressed, the movable plate continues to slide. The lower end of the ejector rod contacts the bottom of the slot, and the positioning slot slides out from the upper end of the lower die. The positioning slot is then separated from the corners of the material. The positioning slots ensure the precise positioning of the material before stamping, which helps to improve the dimensional and shape accuracy of the stamped product. By limiting the corners of the material, the movement or offset of the material during the stamping process can be reduced, thereby ensuring the quality of the stamped product.

[0014] 2. During the process of the ejector pin sliding into the groove, the lower end of the ring plate contacts the upper end of the plate. As the ejector pin continues to slide, the ring plate slides on the side wall of the ejector pin, and the second torsion spring contracts, thereby slowing down the sliding speed of the movable plate. The elastic force of the second torsion spring helps to maintain the stability of the ejector pin during the sliding process, reducing the direct friction and collision between the ring plate and the plate, thereby reducing the risk of wear and damage to the parts, and avoiding excessive impact force when the upper and lower molds are closed, which could lead to damage to the upper and lower molds.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A stamping die material positioning structure includes a base 001, a lower die 101 fixedly connected to the upper end of the base 001, and multiple plates 102 fixedly connected in a rectangular array at the upper end of the base 001. Each plate 102 has a slot 103 at its upper end and a sliding groove 104 on its side wall. A movable block 105 is slidably connected inside the sliding groove 104, and a slot 107 is provided through the movable block 105. A positioning groove 108 is provided on the side wall of the movable block 105. An upper seat 002 is located above the base 001, and a movable plate 203 is slidably connected to the lower end of the upper seat 002. An upper die 204 is fixedly connected to the lower end of the movable plate 203, and multiple push rods 205 are fixedly connected in a rectangular array at the lower end of the movable plate 203. One side of the slot 107 and the side wall of the push rods 205 are inclined. When stamping is required, the operator places the four corners of the rectangular material onto the four movable blocks 102. Inside the side wall positioning groove 108, multiple positioning grooves 108 are used to position and support the material. Then, the movable plate 203 drives the upper mold 204 and multiple ejector rods 205 to slide downward. First, the ejector rods 205 slide through the hole groove 103 to the inside of the groove 107. The inclined wall of the ejector rod 205 contacts the inclined inner wall of the groove 107, causing the movable block 105 to slide into the sliding groove 104. The movable plate 203 continues to slide, the lower end of the upper mold 204 contacts the upper end of the material, and the lower end of the ejector rod 205 contacts the bottom of the hole groove 103. The positioning groove 108 slides out from the upper end of the lower mold 101 and the positioning groove 108 disengages from the corner of the material. Then, the upper mold 204 and the lower mold 101 close the mold to stamp and form the material. Then, the movable plate 203 drives the upper mold 204 and multiple ejector rods 205 to slide upward, causing the ejector rods 205 to slide out from the inside of the hole groove 103, and the upper mold 204 and the lower mold 101 are demolded.

[0023] A torsion spring 106 is fixedly connected to the inner wall of the slide groove 104. The end of the torsion spring 106 is fixedly connected to the side wall of the movable block 105. When the movable block 105 is pushed into the slide groove 104, the torsion spring 106 is compressed. When the thrust disappears, the energy of the torsion spring 106 is released, thereby pushing the movable block 105 to automatically slide and reset.

[0024] Multiple support rods 109 are fixedly connected to the upper end of the base 001. The multiple support rods 109 are distributed in a rectangular array. The upper end of the support rods 109 is fixedly connected to the lower end of the upper seat 002, and the upper seat 002 is supported by the multiple support rods 109.

[0025] A hydraulic cylinder 201 is fixedly connected to the upper end of the upper seat 002. The output end of the hydraulic cylinder 201 is fixedly connected to the upper end of the movable plate 203. The hydraulic cylinder 201 is connected to an external hydraulic pump. The output end of the hydraulic cylinder 201 pushes or pulls the movable plate 203 to slide up and down.

[0026] The upper part of the upper seat 002 has two guide rods 202 that slide through it. The lower end of the guide rods 202 is fixedly connected to the upper end of the movable plate 203. When the movable plate 203 slides up and down, it is guided and limited by the guide rods 202.

[0027] Multiple torsion springs 206 are fixedly connected to the lower end of the movable plate 203. The multiple torsion springs 206 are distributed in a rectangular array. The torsion springs 206 are sleeved on the outside of the top rod 205. A ring plate 207 is slidably connected to the side wall of the top rod 205. The ends of the torsion springs 206 are fixedly connected to the upper end of the ring plate 207. During the process of the top rod 205 sliding into the groove 103, the lower end of the ring plate 207 contacts the upper end of the plate 102. As the top rod 205 continues to slide, the ring plate 207 slides on the side wall of the top rod 205, and the torsion springs 206 retract.

[0028] In this invention, when it is necessary to stamp materials, the operator places the four corners of the rectangular material into the positioning grooves 108 on the side walls of the four movable blocks 105. The material is positioned by the multiple positioning grooves 108. The output end of the hydraulic cylinder 201 pushes the movable plate 203 to slide downward. The movable plate 203 drives the upper mold 204 and multiple push rods 205 to slide downward. First, the push rods 205 slide through the hole groove 103 to the inside of the groove 107. The inclined wall of the push rod 205 contacts the inclined inner wall of the groove 107, causing the movable block 105 to slide into the sliding groove 104. The torsion spring 106 is compressed, the movable plate 203 continues to slide, the lower end of the upper mold 204 contacts the upper end of the material, and the lower end of the push rod 205 contacts the bottom of the hole groove 103. The positioning grooves 108 slide out from the upper end of the lower mold 101 and disengage from the corners of the material. Then the upper mold 204 and the lower mold 101 close the mold to stamp the material.

[0029] As the push rod 205 slides into the slot 103, the lower end of the ring plate 207 contacts the upper end of the plate 102. As the push rod 205 continues to slide, the ring plate 207 slides on the side wall of the push rod 205, and the torsion spring 206 contracts, thereby slowing down the sliding speed of the movable plate 203.

[0030] After the material is stamped, the output end of the hydraulic cylinder 201 pulls the movable plate 203 to slide upward. The movable plate 203 drives the upper mold 204 and multiple ejector rods 205 to slide upward, causing the ejector rods 205 to slide out of the slot 103. The upper mold 204 and the lower mold 101 are then demolded. The second torsion spring 206 releases energy, causing the ring plate 207 to automatically slide back to its original position. At the same time, the energy of the first torsion spring 106 is released, thereby pushing the movable block 105 to automatically slide back to its original position. Then, the stamped material is taken out. The material undergoes plastic deformation after stamping compared to its original size. Therefore, after the movable block 105 is reset, it will not affect the material when it needs to be taken out.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
