Description

Technical Field

[0001] This utility model relates to the field of punching die tooling technology, specifically a punching die tooling that facilitates the cleaning of waste materials. Background Technology

[0002] 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 called cold stamping dies (commonly known as 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 plastically deform, thereby obtaining the desired parts.

[0003] Existing punching dies are not convenient for cleaning the debris generated during punching. The accumulation of debris can easily cause blockage. If the blockage is not cleaned in time, the debris will squeeze the die, causing damage to the die. It is also inconvenient to process the stamped parts.

[0004] Based on this, a punching die tooling that facilitates waste cleaning is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-5As shown, a punching die fixture that facilitates cleaning of waste includes a lower die base 1. Guide rods 2 are fixedly installed at the four corners of the top of the lower die base 1. Lifting plates 3 are slidably installed on the outside of the four guide rods 2. An inspection door 11 is rotatably installed on one side of the lower die base 1 via a hinge.

[0027] The bottom of the lower mold base 1 is equipped with a waste discharge mechanism 4, the top of the lifting plate 3 is equipped with a material ejection mechanism 5 and a stabilizing mechanism 6, and the bottom of the lifting plate 3 is equipped with an anti-blocking mechanism 7.

[0028] In this embodiment, a positioning post is provided on the top of the lower die base 1. The part to be punched is placed on the top of the lower die base 1 through the positioning post. The stabilizing mechanism 6 is connected to the hydraulic mechanism. The hydraulic mechanism drives the lifting plate 3 to move downward, so that the anti-blocking mechanism 7 can punch the part. The debris generated by punching is discharged outward by the waste discharge mechanism 4, so that there will be no accumulation and blockage. At the same time, no manual cleaning is required, which improves the processing efficiency. After the punching is completed, the hydraulic mechanism drives the lifting plate 3 to move upward, so that the ejector mechanism 5 ejects the part, which facilitates the unloading of the part and improves its practicality.

[0029] In one embodiment, such as Figure 1 and Figure 2 As shown, the waste discharge mechanism 4 includes a motor 41 and two fixed blocks 42. The motor 41 and the two fixed blocks 42 are all fixedly installed at the bottom inside the lower mold base 1. A transmission shaft 43 is rotatably mounted between the two fixed blocks 42. A first gear 44 is keyed to the outside of the transmission shaft 43. A second gear 45 is keyed to the output end of the motor 41, and the second gear 45 meshes with the first gear 44. Cams 46 are fixedly mounted at both ends of the transmission shaft 43. A first connecting rod 47 is rotatably mounted on one side of each of the two cams 46. A blanking plate 48 is rotatably mounted on one end of the first connecting rod 47. Limiting grooves 8 are opened on both sides of the lower die base 1. The blanking plate 48 is slidably mounted to the lower die base 1 through the limiting grooves 8. The motor 41 drives the second gear 45 to rotate. The second gear 45 drives the transmission shaft 43 to rotate through the first gear 44. Due to the cooperation between the cam 46 and the first connecting rod 47, the blanking plate 48 slides back and forth inside the limiting grooves 8, effectively shaking off the debris generated by stamping from above the blanking plate 48. No manual cleaning is required, and there will be no debris accumulation and blockage.

[0030] In one embodiment, such as Figure 1 and Figure 3As shown, the ejector mechanism 5 includes a mounting frame 51 and two cylinders 55. The mounting frame 51 is fixedly mounted on the top of the lifting plate 3. An air bladder 52 is installed inside the mounting frame 51. A pressure plate 53 is slidably mounted inside the mounting frame 51 and above the air bladder 52. A pressure rod 54 is fixedly mounted on the top of the pressure plate 53, and the top end of the pressure rod 54 extends through the mounting frame 51 to the outside. Both cylinders 55 are fixedly mounted on the top of the lower mold base 1. An ejector plate 56 is fixedly mounted between the tops of the two cylinders 55, and the ejector plate 56 is located inside the lower mold base 1. A discharge groove 57 is opened on the top of the ejector plate 56. Ejector rods 58 are fixedly connected to the four corners of the top of the ejector plate 56. The top ends of the ejector rods 58 penetrate the lower mold base 1 and extend to the outside. Externally, an air guide pipe 59 is installed between the airbag 52 and the cylinder 55. When the stamping is completed, the lifting plate 3 moves upward, and the top of the pressure rod 54 contacts the stamping equipment. The pressure plate 53 pressurizes the airbag 52, and the gas inside the airbag 52 enters the cylinder 55 through the air guide pipe 59. The air pressure inside the cylinder 55 increases, causing the top plate 56 to move upward. The top rod 58 passes through the lower die base 1, thereby pushing out the part placed on the top of the lower die base 1 for easy unloading. After unloading is completed, the lifting plate 3 moves downward slightly, causing the top plate 56 to move downward to avoid the top rod 58 affecting the loading of the part. After the part is loaded, the lifting plate 3 moves downward, the pressure of the airbag 52 is released, and the cylinder 55 drives the top plate 56 to move downward. Therefore, the top rod 58 will not interfere with the normal stamping of the part.

[0031] In one embodiment, such as Figure 1 and Figure 4 As shown, the stabilizing mechanism 6 includes a fixed rod 61, which is fixedly installed at the top center point of the lifting plate 3. A sliding sleeve 62 is slidably installed on the outside of the fixed rod 61. A first mounting seat 63 is fixedly installed in a ring at equal intervals on the outside of the sliding sleeve 62. A second connecting rod 64 is rotatably installed inside the first mounting seat 63. A second mounting seat 65 is rotatably installed at one end of the second connecting rod 64. A second sliding groove 10 is opened on the top of the lifting plate 3. The second mounting seat 65 is slidably installed with the lifting plate 3 through the second sliding groove 10. The hydraulic mechanism is connected to the sliding sleeve 62. When the hydraulic mechanism presses down, the lifting plate 3 moves downward until the anti-blocking mechanism 7 contacts the part. The hydraulic mechanism continues to move downward. At this time, due to the action of the second connecting rod 64 and the second sliding groove 10, the four second mounting seats 65 slide to the four corners of the lifting plate 3, thereby ensuring that the lifting plate 3 is subjected to uniform force and improving the stamping quality.

[0032] In one embodiment, such as Figure 1 and Figure 5As shown, the anti-blocking mechanism 7 includes an upper mold base 71, which is fixedly installed at the bottom of the lifting plate 3. An installation groove 72 is provided inside the upper mold base 71. A stamping part 73 is fixedly connected to the bottom of the upper mold base 71. A first sliding groove 74 is provided at the bottom of the stamping part 73. A reset plate 75 is slidably installed inside the installation groove 72. A slider 77 is slidably installed inside the first sliding groove 74, and the slider 77 is fixedly connected to the reset plate 75. Springs are fixedly installed at equal intervals on the top of the reset plate 75. Spring 76 is fixedly installed at the top of upper mold base 71. The top of lower mold base 1 is provided with stamping groove 9, and stamping groove 9 is adapted to stamping part 73. During stamping, stamping part 73 makes a hole in the part, slider 77 contacts the part, so that reset plate 75 slides upward inside mounting groove 72. Spring 76 is compressed, and the force generated by spring 76 reset makes slider 77 push out the debris generated by the hole, so as to prevent the debris from remaining inside the first slide groove 74. The ejected debris falls to the top of blanking plate 48 through stamping groove 9.

[0033] The above embodiment discloses a punching die fixture that facilitates waste cleaning. The lower die base 1 is provided with a positioning post at its top. The part to be punched is placed on the top of the lower die base 1 through the positioning post. The hydraulic mechanism is connected to the sliding sleeve 62. When the hydraulic mechanism is pressed down, the lifting plate 3 moves downward until the anti-blocking mechanism 7 contacts the part. The hydraulic mechanism continues to move downward. At this time, due to the action of the second connecting rod 64 and the second sliding groove 10, the four second mounting seats 65 slide to the four corners of the lifting plate 3, thereby ensuring that the lifting plate 3 is evenly stressed. During punching, the stamping part 73 punches the part, and the slider 77 contacts the part, causing the reset plate 75 to slide upward inside the mounting groove 72. The spring 76 is compressed, and the force generated by the spring 76 reset causes the slider 77 to push out the debris generated by the punching, preventing the debris from remaining inside the first sliding groove 74. The ejected debris falls to the top of the blanking plate 48 through the punching groove 9.

[0034] After stamping is completed, when the lifting plate 3 moves upward, the top of the pressure rod 54 contacts the stamping equipment, the pressure plate 53 pressurizes the air bag 52, and the gas inside the air bag 52 enters the interior of the cylinder 55 through the air guide pipe 59. The air pressure inside the cylinder 55 increases, causing the ejector plate 56 to move upward, and the ejector rod 58 penetrates the lower die base 1, thereby ejecting the part placed on the top of the lower die base 1 for easy unloading.

[0035] The motor 41 drives the second gear 45 to rotate, and the second gear 45 drives the transmission shaft 43 to rotate through the first gear 44. Due to the cooperation between the cam 46 and the first connecting rod 47, the feeding plate 48 slides back and forth inside the limiting groove 8, effectively shaking off the debris generated by stamping from above the feeding plate 48. No manual cleaning is required, and there will be no debris accumulation and blockage.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
