[0001] The invention relates to the technical field of punching dies, and in particular to a precision punching die for forging a track link and a use method thereof. Background Art

[0002] Track links are key parts of engineering machinery crawlers, and the market demand is huge. Track links work in harsh environments, with complex forces, and need to withstand large random alternating loads in working conditions.

[0032] Reference Figure 1-Figure 7 A precision punching die for forging a track segment comprises a base 1 and a track segment body 10. A plurality of pillars 2 are fixedly installed around the top of the base 1. A top plate 4 is fixedly installed on the top of the plurality of pillars 2. A connecting column 8 is slidably installed in the middle of the top of the top plate 4. A punching knife 7 is fixedly installed at the bottom of the connecting column 8. A groove is provided in the middle of the top of the base 1. A discharge platform 103 is provided in the groove. A positioning column 104 for positioning the track segment body 10 is provided on the top of the discharge platform 103. A lifting plate 5 with a mouth-shaped structure is slidably sleeved on the surface of the plurality of pillars 2. A pressing mechanism 9 is symmetrically provided on the top of the lifting plate 5. Two discharge ports 101 are symmetrically provided on two opposite sides of the base 1. Two equipment cavities 105 are symmetrically provided on the other two sides of the base 1. Each equipment cavity 105 is provided with a cutting mechanism. The present invention sets a pressing mechanism 9, and after the chain track segment body 10 is placed on the top of the discharge platform 103, the chain track segment body 10 is limited by the pressing mechanism 9, thereby improving the stability of the chain track segment body 10 during the punching process of the equipment. At the same time, during the upward movement of the punching knife 7 after punching, the cut edge material is blocked to prevent the edge material from adhering to the surface of the punching knife 7 and being difficult to remove. The edge material can be separated from the punching knife 7 by the pressing mechanism 9 and fall into the groove on the top of the base 1. During the rising process of the lifting plate 5, the cutting mechanism can be driven to cut the edge material, so that it can be automatically discharged from the two discharge ports 101, avoiding the need to discharge the edge material separately, thereby improving the working efficiency of the chain track segment body 10 processing.

[0033] In this embodiment, the pressing mechanism 9 includes a side plate 901 and a support frame 902 with an H-shaped structure. The side plate 901 is fixedly installed on one side of the top of the lifting plate 5. Two mounting holes matching the support frame 902 are opened on the surface of the side plate 901. The support frame 902 is slidably installed in the two mounting holes. A plurality of second springs 904 are fixedly installed between the support frame 902 and the side plate 901. A positioning roller 903 is rotatably installed on one end of the support frame 902 away from the side plate 901.

[0034] When in use, by setting a pressing mechanism 9, after the chain track segment body 10 is embedded on the top of the discharge platform 103, the support frames 902 in the two pressing mechanisms 9 respectively drive the corresponding positioning rollers 903 to press on the top of the chain track segment body 10 under the elastic force of the corresponding second springs 904. After the punching knife 7 completes the edge cutting of the chain track segment body 10, it can prevent the edge material from moving with the punching knife 7, so that the edge material can automatically fall into the groove opened in the base 1, avoiding the need to unload the chain track segment body 10 and the edge material separately after punching, thereby improving work efficiency. At the same time, the positioning roller 903 can be replaced with a grinding strip made of whetstone material that is compatible with half of the outer contour of the punching knife 7, so that it is fixedly installed at one end of the support frame 902, and can be used to grind the outer edge of the punching knife 7 through the combination of the two pressing mechanisms 9, so that the edge remains sharp, thereby improving the smoothness of the equipment in punching edge cutting.

[0035] In this embodiment, the cutting mechanism includes a spur column 13, a second rack 14, a push block 15 and a cutting knife 16. The spur column 13 is rotatably installed on one side of the equipment cavity 105. A cross hole 107 is provided on the side of the equipment cavity 105 close to the unloading table 103. The push block 15 is slidably installed in the cross hole 107. The cutting knife 16 is fixedly installed on one side of the push block 15 close to the unloading table 103. The second rack 14 is fixedly installed on the other side of the push block 15. The surface of the unloading table 103 An avoidance hole 106 adapted to the cutting knife 16 is provided, a grinding blade 17 is fixedly sleeved on the top edge of the discharge table 103, the second rack 14 is meshed with the spur column 13, an inspection door 11 is hinged in the opening of the equipment cavity 105, a channel penetrating the outer surface of the base 1 is provided at the top of the equipment cavity 105, a first rack 12 is slidably installed in the channel, the top of the first rack 12 is fixedly installed on the bottom of the lifting plate 5, and the first rack 12 is meshed with the spur column 13 close to the side of the discharge table 103.

[0036] During use, by setting a cutting mechanism, when the lifting plate 5 is raised to take out and put materials, the lifting plate 5 drives the two first racks 12 to move up, and the two first racks 12 respectively drive the two spur columns 13 to rotate, and the two spur columns 13 respectively drive the two second racks 14 to slide toward the discharge platform 103, thereby driving the two cutting knives 16 to cut the edge materials, and the cut edge materials are discharged from the discharge ports 101 on the two opposite sides of the base 1, thereby improving the linkage consistency of the equipment; a grinding blade 17 is set, so that the inner edge of the punching knife 7 will be ground after each punching to keep it sharp, thereby making the edges of the chain track segment body 10 smoother after punching, which is convenient for subsequent surface finishing, thereby improving the working efficiency of the chain track segment body 10 processing.

[0037] In this embodiment, the opening at the top of the groove is larger than the outer diameter of the chain track segment body 10, the two discharge ports 101 are connected to the groove, and a discharge slope 102 is provided between the discharge port 101 and the groove. A first spring 3 is sleeved on the surface of each pillar 2, and the two ends of each first spring 3 are respectively fixedly installed on the top plate 4 and the lifting plate 5. Two trapezoidal blocks 6 are symmetrically fixedly installed at both ends of the lifting plate 5, and each trapezoidal block 6 has a right-angled trapezoidal structure.

[0038] When in use, a groove is provided to facilitate the collection of edge materials, and a discharge slope 102 is provided so that after the edge materials are cut, the edge materials broken into two pieces will slide out from the two discharge ports 101 along the discharge slope 102 due to their own gravity. By providing a collection box below the discharge port 101, the edge materials can be automatically discharged and collected. The first spring 3 and the second spring 904 are both ceramic springs, which can be better adapted to high temperature environments. A trapezoidal block 6 is provided to facilitate the lifting plate 5 to rise during the process of the robot arm taking and placing materials. At the same time, when the trapezoidal block 6 is against the top of the base 1, the positioning roller 903 in the pressing mechanism 9 is against the surface of the chain track segment body 10 to be punched with appropriate pressure, so as to avoid damage to the surface of the chain track segment body 10, thereby improving the protective effect of the equipment on the product appearance.

[0039] A method for using a precision punching die for forging a track link comprises the following steps:

[0040] S1: First, the base 1 is fixedly installed on the top of the workbench, and then a driving device is fixedly installed on the top of the top plate 4 to control the connection column 8 to slide in the top plate 4, thereby driving the punching knife 7 to move up and down, and then a mechanical arm for loading and unloading is installed next to the workbench;

[0041] S2: The forged track segment body 10 is clamped by the robot arm, and the lifting plate 5 is lifted from one side of the trapezoidal block 6, and then enters the mold, and the track segment body 10 is nested on the top of the unloading platform 103, and then the robot arm is withdrawn. At this time, the lifting plate 5 moves toward the top of the base 1 under the reset force of the first spring 3 until the positioning roller 903 in the pressing mechanism 9 is against the top of the track segment body 10;

[0042] S3: Start the corresponding driving device to drive the punching knife 7 to descend and cut the flash of the chain track segment body 10. During the punching process, the two positioning rollers 903 are pressed against the outer surface of the punching knife 7 under the action of the corresponding second spring 904. When the punching knife 7 moves upward, the positioning rollers 903 can prevent the cut edge material from adhering to the surface of the punching knife 7, so that the edge material can automatically break away and fall into the groove on the top of the base 1.

[0043] S4: The lifting plate 5 is lifted by the robot arm and the chain track segment body 10 after punching is clamped to enter the next process. At the same time, the chain track segment body 10 to be punched is placed on the top of the discharge table 103. Each time the lifting plate 5 rises, the first rack 12 can drive the cutting mechanism in the equipment cavity 105 to cut the edge material falling into the groove, so that the edge material can be automatically discharged from the base 1 from the two discharge ports 101, and a collection box is set under the two discharge ports 101 to facilitate the automatic centralized collection of the edge material after cutting.
