Description

Technical Field

[0001] This utility model relates to the field of high-strength angle steel punching device, specifically a high-strength angle steel punching device for power transmission towers. Background Technology

[0002] High-strength angle steel is an essential component in the construction of power transmission towers. To connect high-strength angle steel to other components, holes are often punched in the steel to create through-holes. Bolts are then passed through these holes, and nuts are tightened onto the bolts to complete the installation. Punching these holes in the high-strength angle steel is typically done using a punching machine.

[0003] A stamping machine typically consists of a machine body, a hydraulic mechanism, a worktable, a lower die base, a lower die, an upper die base, an upper die, and a control system. The worktable is located on the machine body, and the hydraulic mechanism and control system are mounted on the machine body. The lower die base is fixed on the worktable, and the lower die is fixed on the lower die base, which has a cavity. The upper die base is fixed on the hydraulic rod of the hydraulic mechanism, and the upper die is fixed on the upper die base. A cutting tool is fixed on the upper die base, and the cutting tool of the upper die is aligned with the cavity of the lower die. During punching, a high-strength angle steel is placed on the lower die, and then the operation button of the control system is pressed. The control system controls the hydraulic rod of the hydraulic mechanism to move downward, which in turn moves the upper die base downward. This causes the cutting tool on the upper die to press onto the high-strength angle steel and continue to move downward rapidly, cutting off the part of the high-strength angle steel that is in contact with the cutting tool and pressing it into the cavity of the lower die, thus completing the punching of the high-strength angle steel. Punching high-strength angle steel used for power transmission towers with a punching machine has advantages such as high production efficiency, high hole position accuracy, good hole surface quality and edge shape, and low cost for mass production, and is therefore widely used.

[0004] However, in existing high-strength angle steel punching devices used for power transmission towers, when punching large quantities of high-strength angle steel, workers need to manually remove the punched high-strength angle steel from the lower die, place new high-strength angle steel on the lower die, and start the punching machine. Frequent repetitive work can easily lead to workers forgetting to remove their hands from the space between the upper and lower dies when they start the punching machine, resulting in dangerous situations where their hands are crushed and disabled. Such accidents are common in actual production, and the injuries to workers are extremely serious, so a solution is urgently needed. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength angle steel punching device for power transmission towers, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a punching device for high-strength angle steel in power transmission towers, comprising: a punching machine body, a worktable on the punching machine body, a lower die base fixed on the worktable, a lower die fixed on the lower die base, a die cavity on the lower die, a hydraulic mechanism fixed on the punching machine body, an upper die base fixed on the hydraulic rod of the hydraulic mechanism, an upper die fixed at the bottom of the upper die base, a slide rail fixed on the lower die base, a first workpiece placement rack and a second workpiece placement rack slidably connected on the slide rail, a connecting plate fixed between the first workpiece placement rack and the second workpiece placement rack, workpiece limiting grooves and clearance holes on both the first workpiece placement rack and the second workpiece placement rack, and limiting mechanisms provided between the slide rail and the first workpiece placement rack and between the slide rail and the second workpiece placement rack.

[0007] Preferably, both the first workpiece placement rack and the second workpiece placement rack are in the shape of an "I" plate. Each of the four bottom corners of the first workpiece placement rack and the second workpiece placement rack is fixed with a slider. The slider is in the shape of a rectangular block and a track groove is provided on the slide rail. The slider is slidably connected in the track groove.

[0008] Preferably, the limiting mechanism includes: limiting holes, limiting rod insertion holes, and limiting rods. Limiting holes are provided on one set of sliders on the first workpiece placement rack and one set of sliders on the second workpiece placement rack. Two sets of limiting rod insertion holes are provided on the slide rail. The two sets of limiting rod insertion holes are symmetrically distributed about the press body. One end of a limiting rod is movably inserted into the limiting rod insertion hole. One end of one set of limiting rods extending out of the limiting rod insertion hole is movably inserted into one set of limiting holes, and one end of the other set of limiting rods extending out of the limiting rod insertion hole is movably inserted into the other set of limiting holes.

[0009] Preferably, two sets of limiting mechanism mounting seats are fixed on the slide rail. One end of the limiting mechanism mounting seat is provided with a limiting rod storage groove, and the limiting rod storage grooves on the two sets of limiting mechanism mounting seats are respectively aligned with the two sets of limiting rod insertion holes.

[0010] Preferably, the other end of the mounting base of the limiting mechanism is provided with a pull rod hole, and a pull rod is movably inserted into the pull rod hole. The pull rod is in the shape of a "T" and one end of the pull rod extends into the limiting rod receiving groove and is fixed on the limiting rod.

[0011] Preferably, a rubber pad is fixed on the inner wall of the pull rod hole. The rubber pad has a circular sheet structure, and the inner ring of the rubber pad abuts against the rod body of the pull rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The high-strength angle steel punching device for power transmission towers proposed in this utility model utilizes the sliding of a first workpiece placement rack and a second workpiece placement rack on a slide rail. When one of the first and second workpiece placement racks moves between the lower and upper die bases, the other must be outside of them. Therefore, the action of picking up and placing the high-strength angle steel is performed on the first or second workpiece placement rack located outside the lower and upper die bases. Simultaneously, the hand pushing the first or second workpiece placement rack and the hand activating the control system on the punching machine body are always the same hand. This ensures that when the control system is activated, the worker's hand has already been withdrawn from between the lower and upper die bases. This allows the punching device to guarantee punching efficiency while also protecting the worker's personal safety. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example 1: Please refer to Figures 1-5This utility model provides a technical solution: a high-strength angle steel punching device for power transmission towers, comprising: a punching machine body 1, a worktable 2 on the punching machine body 1, a lower die base 3 fixed on the worktable 2, a lower die 4 fixed on the lower die base 3, a die cavity 13 on the lower die 4, a hydraulic mechanism fixed on the punching machine body 1, an upper die base 5 fixed on the hydraulic rod of the hydraulic mechanism, an upper die 6 fixed at the bottom end of the upper die base 5, a slide rail 7 fixed on the lower die base 3, a first workpiece placement rack 8 and a second workpiece placement rack 9 slidably connected to the slide rail 7, a connecting plate 10 fixed between the first workpiece placement rack 8 and the second workpiece placement rack 9, workpiece limiting grooves 11 and clearance holes 12 on both the first workpiece placement rack 8 and the second workpiece placement rack 9, and limiting mechanisms provided between the slide rail 7 and the first workpiece placement rack 8 and between the slide rail 7 and the second workpiece placement rack 9.

[0017] A first workpiece placement rack 8 and a second workpiece placement rack 9 are slidably connected to the slide rail 7. A connecting plate 10 is fixed between the first workpiece placement rack 8 and the second workpiece placement rack 9. When the first workpiece placement rack 8 is located between the lower mold base 3 and the upper mold base 5, the second workpiece placement rack 9 is located outside the lower mold base 3 and the upper mold base 5. The worker places a set of high-strength angle steel in the workpiece limiting groove 11 on the second workpiece placement rack 9, and then pushes the second workpiece placement rack 9 between the lower mold base 3 and the upper mold base 5 with one hand. At this time, the first workpiece placement rack 8 is pushed out between the lower mold base 3 and the upper mold base 5. The worker's other hand operates the limiting mechanism to limit the first workpiece placement rack 8 and the slide rail 7, and the second workpiece placement rack 9 is also limited along with it. The clearance hole 12 on the workpiece placement rack 9 is aligned with the mold cavity 13. Then, the worker pulls out the hand used to push the second workpiece placement rack 9 and starts the control system on the press machine body 1. The hydraulic mechanism on the press machine body 1 drives the upper mold base 5 and the upper mold 6 to move downwards. The cutter on the upper mold 6 presses over the high-strength angle steel and inserts into the clearance hole 12 on the second workpiece placement rack 9 and the mold cavity 13 on the lower mold 4, thus completing the punching of the high-strength angle steel. While the punching device is punching the high-strength angle steel on the second workpiece placement rack 9, the worker places another high-strength angle steel into the workpiece limiting groove 11 opened on the first workpiece placement rack 8. After the high-strength angle steel on the second workpiece placement rack 9 has completed punching, the worker... A worker uses one hand to release the limiting mechanism between the slide rail 7 and the first workpiece placement rack 8. Then, using the same hand, the first workpiece placement rack 8 is pushed back between the upper die base 5 and the lower die base 3, causing the second workpiece placement rack 9 to be pushed out again. The worker uses their other hand to operate the limiting mechanism to limit the second workpiece placement rack 9 to the slide rail 7, while simultaneously pulling out the hand holding the first workpiece placement rack 8 and activating the control system on the stamping machine body 1. While the punching device punches holes in the high-strength angle steel on the first workpiece placement rack 8, the worker removes the punched high-strength angle steel from the second workpiece placement rack 9 and places the next set of high-strength angle steel to be punched into the workpiece limiting groove 11 on the second workpiece placement rack 9. The process continues with the first workpiece placement rack... The sliding of the first workpiece placement rack 8 and the second workpiece placement rack 9 on the slide rail 7 ensures that when one of the first workpiece placement rack 8 and the second workpiece placement rack 9 moves between the lower die base 3 and the upper die base 5, the other must be outside the lower die base 3 and the upper die base 5. Thus, the action of picking up and placing high-strength angle steel is performed on the one of the first workpiece placement rack 8 and the second workpiece placement rack 9 located outside the lower die base 3 and the upper die base 5. At the same time, the hand pushing the first workpiece placement rack 8 or the second workpiece placement rack 9 and the hand starting the control system on the press body 1 are always the same hand, thereby ensuring that when the control system is started, the worker's hand must have been withdrawn from between the lower die base 3 and the upper die base 5. This ensures that the punching device protects the worker's personal safety while ensuring punching efficiency.

[0018] Example 2: Based on Example 1, in order to realize the operation of the limiting mechanism, both the first workpiece placement rack 8 and the second workpiece placement rack 9 are "I"-shaped plate structures. Slider 14 is fixed at the four corners of the bottom of both the first workpiece placement rack 8 and the second workpiece placement rack 9. The slider 14 is a rectangular block structure. Track grooves 15 are provided on the slide rail 7, and the slider 14 is slidably connected in the track grooves 15. The limiting mechanism includes: limiting holes 17, limiting rod insertion holes 18, and limiting rods 20. Limiting holes 17 are provided on one set of sliders 14 on the first workpiece placement rack 8 and one set of sliders 14 on the second workpiece placement rack 9. Two sets of limiting rod insertion holes 18 are provided on the slide rail 7. The two sets of limiting rod insertion holes 18 are symmetrically distributed about the press body 1. One end of a limiting rod 20 is movably inserted into the hole 18. One set of limiting rods 20 extends out of the limiting rod insertion hole 18 and is movably inserted into one set of limiting holes 17. The other set of limiting rods 20 extends out of the limiting rod insertion hole 18 and is movably inserted into another set of limiting holes 17. Two sets of limiting mechanism mounting seats 16 are fixed on the slide rail 7. One end of the limiting mechanism mounting seat 16 is provided with a limiting rod storage groove 19. The limiting rod storage grooves 19 on the two sets of limiting mechanism mounting seats 16 are aligned with the two sets of limiting rod insertion holes 18 respectively. The other end of the limiting mechanism mounting seat 16 is provided with a pull rod hole 21. A pull rod 22 is movably inserted into the pull rod hole 21. The pull rod 22 is a "T"-shaped rod. One end of the pull rod 22 extends into the limiting rod storage groove 19 and is fixed on the limiting rod 20.

[0019] When the second workpiece placement rack 9 is pushed out of the space between the lower mold base 3 and the upper mold base 5, a set of sliders 14 with limit holes 17 on the second workpiece placement rack 9 slides to the end of the track groove 15. At this time, the limit hole 17 at the bottom of the second workpiece placement rack 9 is aligned with the limit rod insertion hole 18. The thin rod of the pull rod 22 is fully pushed into the pull rod hole 21. The pull rod 22 pushes one end of the limit rod 20 into the limit hole 17 and the other end of the limit rod 20 into the limit rod insertion hole 18, thereby realizing the limitation between the starting slide rail 7 and the second workpiece placement rack 9. When the pull rod 22 is pulled out of the pull rod hole 21, the pull rod 22 pulls the limit rod 20 into the limit rod storage groove 19, thereby releasing the limitation between the slide rail 7 and the second workpiece placement rack 9. When the two workpiece placement racks 9 are pushed into the space between the lower mold base 3 and the upper mold base 5, a set of sliders 14 with a limiting hole 17 at the bottom of the first workpiece placement rack 8 slides to the other end of the track groove 15. At this time, the limiting hole 17 at the bottom of the first workpiece placement rack 8 is aligned with the limiting rod insertion hole 18. Similarly, another set of pull rods 22 is pushed into the limiting rod storage groove 19, so that another set of limiting rods 20 is inserted into the limiting hole 17 and the limiting rod insertion hole 18 at the bottom of the first workpiece placement rack 8, thereby realizing the limiting between the starting slide rail 7 and the first workpiece placement rack 8. Similarly, the pull rods 22 are pulled out from the pull rod hole 21, so that the limiting rods 20 move into the limiting rod storage groove 19, thereby realizing the release of the limiting between the slide rail 7 and the first workpiece placement rack 8.

[0020] Example 3: Based on Example 2, in order to prevent the pull rod 22 from moving around, a rubber pad 23 is fixed on the inner wall of the pull rod hole 21. The rubber pad 23 has a circular sheet structure, and the inner ring of the rubber pad 23 abuts against the rod body of the pull rod 22.

[0021] A rubber pad 23 is fixed on the inner wall of the pull rod hole 21. The rubber pad 23 is made of a rough-surfaced rubber material, which generates a certain amount of damping between the rubber pad 23 and the pull rod 22, thereby preventing the pull rod 22 from moving around when no operation is performed.

[0022] In actual use, pulling the second workpiece placement rack 9 causes the slider 14 at the bottom of the second workpiece placement rack 9 to move to the end of the track groove 15, placing the high-strength angle steel in the workpiece limiting groove 11 on the second workpiece placement rack 9. Then, pushing the second workpiece placement rack 9 pushes it between the lower die base 3 and the upper die base 5, while the first workpiece placement rack 8 is pushed out between the lower die base 3 and the upper die base 5. The slider 14 at the bottom of the first workpiece placement rack 8 moves to the other end of the track groove 15, activating the limiting mechanism to limit the first workpiece placement rack 8. The second workpiece placement rack 9 is also limited. Simultaneously, the control system on the press body 1 is activated, and another set of high-strength angle steel is placed in the workpiece limiting groove 11 on the first workpiece placement rack 8. After the press completes punching the high-strength angle steel on the second workpiece placement rack 9, the limiting mechanism is released from limiting the first workpiece placement rack 8, and the first workpiece placement rack 8 is pushed to the lower die base 3 and the upper die base 5. Between the mold base 3 and the upper mold base 5, the second workpiece placement rack 9 is pushed out between the lower mold base 3 and the upper mold base 5. The slider 14 at the bottom of the second workpiece placement rack 9 moves again to the end of the track groove 15, and the limiting mechanism is activated to limit the second workpiece placement rack 9. The first workpiece placement rack 8 is also limited. At the same time, the control system on the press body 1 is activated, and the high-strength angle steel that has been punched on the second workpiece placement rack 9 is removed from the second workpiece placement rack 9. Another set of high-strength angle steel to be punched is placed into the workpiece limiting groove 11 on the second workpiece placement rack 9. At the same time, the press completes the punching of the high-strength angle steel on the first workpiece placement rack 8. By repeating the above process, the high-strength angle steel can be punched efficiently. Meanwhile, the loading and unloading of the high-strength angle steel as workpieces is carried out in the space outside the lower mold base 3 and the upper mold base 5, which can prevent workers from accidentally activating the control system on the press body 1 during loading and unloading, which could lead to their hands being squeezed and maimed.
