Description

Technical Field

[0001] This utility model belongs to the field of copper busbar production technology, and specifically relates to a punching device for copper busbar production. Background Technology

[0002] Copper busbars are rectangular or chamfered rectangular strip conductors made of copper. They have excellent electrical conductivity, thermal conductivity, and mechanical strength. The surface is often tin-plated or passivated to enhance corrosion resistance. They come in various specifications, and different cross-sectional areas can be selected according to current load requirements. They are widely used in power systems such as high and low voltage electrical appliances, switchgear, and power distribution equipment. As conductive busbars, they connect various electrical devices to realize the transmission and distribution of electrical energy. Compared with cables, copper busbars have a large current carrying capacity and are easy to install, making them a highly efficient conductive connection component in power engineering.

[0003] When punching copper busbars, the waste material punched from the surface of the copper busbars can easily clog the material discharge holes on the surface of the equipment. As a result, after the work is completed, the material discharge holes need to be cleaned manually, which is time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this utility model is to provide a punching device for copper busbar production, which has the advantage of automatically cleaning up the waste material blocking the inside of the discharge hole.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a punching device for copper busbar production, comprising a base plate, a cylinder bolted to one side of the base plate, a pressure plate bolted to the piston end of the cylinder, a sliding column slidably connected to one end of the pressure plate, a turntable rotatably connected to the surface of the sliding column, five sets of punches detachably connected inside the turntable, a sliding groove provided at the upper end of the base plate, a material discharge hole provided inside the sliding groove, a clamping plate bolted to the surface of each of the five sets of punches, a material discharge assembly provided inside the base plate, a protective assembly provided on one side of the material discharge assembly, and a lubrication assembly provided on the other side of the material discharge assembly.

[0006] Using the above technical solution, during use, the turntable is rotated according to the shape of the punching required. After rotation, the turntable switches to the corresponding punch at the lower end of the pressure plate. At this time, the clamping plate on the surface of the punch will engage inside the lubrication assembly. Then, the copper busbar to be processed is placed on the upper end of the slide groove. Subsequently, the cylinder is activated, which drives the pressure plate to press down and slide on the surface of the slide column. During the pressing process, the pressure plate will press down on the punch, and the lubrication assembly will drive the material feeding assembly to run, so that the material feeding structure is in a close fit, thereby punching the copper busbar. When the punching is completed and the punch drives the lubrication assembly to move upward, the material feeding structure will be opened. At this time, the waste material blocked inside the material feeding structure will automatically fall out from the material feeding hole. During the punching process, the protective assembly will continue to rotate, which can protect the important internal structure.

At this time, the clamping plate on the surface of the punch will engage inside the lubrication component. Then, the copper busbar to be processed is placed on the upper end of the slide groove. Then, the cylinder is activated, which drives the pressure plate to press down and slide on the surface of the slide column.

Detailed Implementation

[0037] The present invention will be further described in detail below with reference to the accompanying drawings.

A gear 1008 is bolted to one end of the positive and negative screw rods 1007.

[0043] Protective component 9 includes a fixed base 902, which is welded to the lower end of the base plate 1. A motor 901 is bolted inside the base plate 1. A rotating housing 903 is fixedly connected to the output end of the motor 901 via a coupling. A first friction wheel 904 is welded to one end of the rotating housing 903. A telescopic rod 906 is welded to one side of the motor 901. Two sets of threaded sleeves 907 are threaded onto the surface of a positive and negative lead screw 1007. The telescopic rod 906 is fixedly connected to one set of threaded sleeves 907. A rotating wheel 909 is rotatably connected to the surface of the threaded sleeve 907. One set of rotating wheels 909 has a... The second friction wheel 908 is detachably connected to the first friction wheel 904. A positioning plate 910 is welded to one side of another set of rotating wheels 909. A telescopic column 914 is bolted to another set of threaded sleeves 907 and support plate 1009. Several sets of positioning holes 911 are opened on the surface of the positioning plate 910. A first spring push rod 912 is detachably connected inside one set of positioning holes 911, and the first spring push rod 912 is bolted to the inside of the moving plate 1006. A telescopic shell 913 is bolted between the two sets of rotating wheels 909.

[0044] The lubrication assembly 8 includes a sliding housing 801, which is slidably connected to the inside of the base plate 1. A toothed plate 802 is slidably connected inside the sliding housing 801. A one-way screw 804 is threadedly connected inside the toothed plate 802. A handle 806 is welded to one end of the one-way screw 804. A retainer 805 is welded to one side of the sliding housing 801, and the retainer 805 is detachably connected to the retaining plate 6. A push rod 803 is welded to one side of the toothed plate 802. A connecting block 812 is welded to the lower surface of the base plate 1.

A limit plate 807 is detachably connected inside the push plate 808, and the limit plate 807 is slidably connected to the base plate 1.

[0045] Brief description of usage: When using, select the appropriate perforated plate 1005 according to the required perforation shape (the shape of the internal hole of the perforated plate 1005 determines the shape of the perforation on the copper busbar surface). After selection, pull the positioning plate 1003 outwards. Then, install the positioning block 1004 inside the movable housing 1001. The spring rod 1002 will pull the positioning plate 1003 back to its original position and insert it into the positioning block 1004. This completes the setup of the positioning block 1004 and the perforated plate 1005. After fixing, the turntable 12 is rotated according to the selected punching plate 1005, so that the punch 5, whose surface corresponds to the shape of the hole inside the punching plate 1005, is located at the lower end of the pressure plate 3. At this time, the clamping plate 6 on the surface of the punch 5 will be located inside the clamping housing 805. Then, the copper busbar to be punched is placed at the upper end of the slide groove 11. As the cylinder 2 runs, it will drive the pressure plate 3 to move down. The pressure plate 3 will push the punch 5 down to punch the copper busbar. When the punch 5 moves down, it will utilize... The clamping plate 6 moves the clamping case 805 downwards. The downward movement of the clamping case 805 causes the sliding case 801 to slide downwards inside the base plate 1. The downward movement of the sliding case 801 causes the gear plate 802 to move downwards simultaneously. The downward movement of the gear plate 802 causes the gear 1008 to rotate. The rotation of the gear 1008 causes the forward and reverse lead screws 1007 to rotate. The rotation of the forward and reverse lead screws 1007 causes the two sets of threaded sleeves 907 to move synchronously in opposite directions. The design of the telescopic rod 906 and the telescopic column 914 can adjust the position of the threaded sleeves 907. The movement of screw sleeve 907 is limited to prevent it from rotating with the positive and negative screw 1007. When screw sleeve 907 moves, it will cause the telescopic rod 906 and telescopic column 914 to stretch or compress. The movement of screw sleeve 907 will also cause the rotating wheel 909 to move synchronously. The movement of rotating wheel 909 will cause the shifting plate 1006 to move synchronously. The movement of shifting plate 1006 will cause the shifting housing 1001 to move in opposite directions inside the slide groove 11, so that the two sets of perforated plates 1005 are in contact (e.g., ...). Figure 8As shown), the holes in the two sets of perforated plates 1005 can complete the punching of the corresponding copper busbar holes. When the two sets of perforated plates 1005 are attached, the toothed plate 802 will disengage from the gear 1008, so the toothed plate 802 will not drive the gear 1008 to rotate as it continues to move downward, thus allowing the two sets of perforated plates 1005 to fit together. After the two sets of perforated plates 1005 are attached, the puncher 5 has not yet contacted the copper busbar, so the toothed plate 802 will continue to move downward a certain distance (as long as the thickness of the copper busbar to be punched is less than the distance that the toothed plate 802 continues to move, the punching of the copper busbar can be completed). Then the puncher 5 will complete the punching of the copper busbar. When the cylinder 2 drives the pressure plate 3 to move upward, the puncher 5 will drive the chuck 805 to enter. As the lead screw 1007 moves upward, it rotates in the opposite direction, causing the two sets of perforated plates 1005 to open to both sides. Simultaneously, the rotation of the lead screw 1007 causes the two sets of threaded sleeves 907 to drive the rotating wheels 909 to move synchronously in opposite directions. As the rotating wheels 909 move, they extend the telescopic housing 913, which protects the lead screw 1007 from damage caused by scrap material impacting the copper busbar surface. When the rotating wheels 909 move a certain distance, the second friction wheel 908 on the surface of one set of rotating wheels 909 contacts the first friction wheel 904. With the motor 901 (permanent magnet synchronous motor 901, with a hollow shaft output and an independent sealing structure inside), the motor... The sealing structure (which does not rotate with the hollow shaft) operates and drives the rotation of the rotating shell 903 (connected to one end of the hollow shaft) and the first friction wheel 904. This, in turn, drives the second friction wheel 908 and the rotating wheel 909 to rotate. Since the positive and negative lead screws 1007 drive the screw sleeve 907 to move back and forth continuously, the rotating wheel 909 is driven by the motor 901 to rotate 72 degrees at the moment the second friction wheel 908 contacts the first friction wheel 904. This, in turn, drives the telescopic shell 913 to rotate 72 degrees. This prevents waste material from constantly hitting the same position on the surface of the telescopic shell 913, thus preventing rapid damage to the telescopic shell 913. When the telescopic shell 913 and the rotating wheel 909 rotate, they drive the positioning plate 910 to rotate, and align the positioning hole 911 with the piston end of the first spring push rod 912. When the device is compressed, the piston end of the first spring push rod 912, being made of tempered glass, will retract when compressed by the positioning hole 911. As the positioning plate 910 rotates 72 degrees, the first spring push rod 912 will be positioned inside another set of positioning holes 911. There are five sets of positioning holes 911, enough for the first spring push rod 912 to be positioned five times. This completes the fixation of the rotated telescopic shell 913. Since the device operates continuously throughout the day, the reciprocating movement between the gear 1008 and the toothed plate 802 reaches 10,000 to 20,000 times. Because the lubricating oil between the toothed plate 802 and the gear 1008 is consumed very quickly, the operation of the device can be stopped (at this time, the toothed plate 802 will be above the gear 1008). Then, the handle 806 is rotated.The rotation of the handle 806 drives the one-way lead screw 804 to rotate. The rotation of the one-way lead screw 804 causes the toothed plate 802 to move upward. The upward movement of the toothed plate 802 causes the push rod 803 to move upward simultaneously. During the upward movement, the push rod 803 pushes the limiting plate 807 out of the push plate 808. At this time, the tooth gap of the toothed plate 802 is just located at one end of the four sets of syringes 809. Then, the push plate 808 is pushed, and the push plate 808 causes the syringes 809 to move. When the front end of the syringe 809 is just inside the gap between the teeth, the baffle 8... Step 11 is blocked by connecting block 812, which then pushes push plate 808, allowing the lubricating oil inside syringe 809 to be precisely injected between the teeth. This method of injecting lubricating oil is not only time-saving and labor-saving, but also effectively controls the amount, thus preventing lubricating oil waste. The lubricating oil inside a set of syringes 809 can be used multiple times. When the lubricating oil inside syringe 809 is used up, the piston end of syringe 809 can be pulled out to the outside of injection port 810, and lubricating oil can be replenished inside syringe 809 through injection port 810.

[0046] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0047] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
