Description

Technical Field

[0002] Copper busbars are rectangular or chamfered rectangular strips made of copper. They have excellent electrical conductivity, thermal conductivity, and mechanical strength. Their surfaces are often tinned or passivated to enhance corrosion resistance. They come in a variety of sizes, with varying cross-sectional areas depending on current load requirements. They are widely used in power systems such as high- and low-voltage electrical equipment, switchgear, and distribution devices. They serve as conductive busbars connecting various electrical devices to achieve power transmission and distribution. Compared to cables, copper busbars have a higher current carrying capacity and are easier to install, making them highly efficient conductive connection components in power engineering. When punching copper busbars, the waste material punched out from the surface of the copper busbar is easily clogged inside the blanking holes on the surface of the equipment. After the work is completed, the blanking holes need to be cleaned manually, which is time-consuming and labor-intensive. Summary of the Invention

The surface of the positioning disc 910 is provided with a plurality of positioning holes 911. One of the positioning holes 911 is detachably connected with a first spring push rod 912 inside the moving plate 1006.

The lubrication assembly 8 includes a sliding shell 801, which is slidably connected to the inside of the base plate 1. A tooth plate 802 is slidably connected to the inside of the sliding shell 801.

[0033] Brief description of the use process: When in use, select the appropriate punching plate 1005 according to the shape of the punching required (the shape of the internal hole of the punching plate 1005 determines the shape of the punching on the surface of the copper bar). After selection, pull the positioning plate 1003 outward, and then install the positioning block 1004 inside the moving shell 1001. The spring pull rod 1002 will pull the positioning plate 1003 to reset and plug it into the positioning block 1004. At this time, the positioning block 1004 and the punching plate 1005 are completed. The turntable 12 is fixed, and then the turntable 12 is rotated according to the selected punching plate 1005, so that the puncher 5 whose surface of the turntable 12 corresponds to the shape of the hole inside the punching plate 1005 is located at the lower end of the pressing plate 3. At this time, the card plate 6 on the surface of the puncher 5 will be located inside the card shell 805, and then the copper bar to be punched is placed on the upper end of the slide 11. As the cylinder 2 runs, the pressing plate 3 will move downward, and the pressing plate 3 will push the puncher 5 downward to punch the copper bar. When the puncher 5 moves downward, it will The card plate 6 drives the card shell 805 to move downward, and the downward movement of the card shell 805 drives the sliding shell 801 to slide downward inside the bottom plate 1. The downward movement of the sliding shell 801 mobilizes the tooth plate 802 to move downward synchronously, and the downward movement of the tooth plate 802 drives the gear 1008 to rotate. The rotation of the gear 1008 drives the forward and reverse screw rods 1007 to rotate. The rotation of the forward and reverse screw rods 1007 causes the two sets of screw sleeves 907 to move synchronously in opposite directions. The design of the telescopic rod 906 and the telescopic column 914 can adjust the screw sleeve 90 7 is limited to prevent the screw sleeve 907 from rotating with the forward and reverse screw rods 1007, and when the screw sleeve 907 moves, it will drive the telescopic rod 906 and the telescopic column 914 to stretch or compress. When the screw sleeve 907 moves, it will drive the rotating wheel 909 to move synchronously. The movement of the rotating wheel 909 will drive the moving plate 1006 to move synchronously. The movement of the moving plate 1006 will drive the moving shell 1001 to move in the opposite direction inside the slide groove 11, so that the two sets of punching plates 1005 fit together (such as Figure 8As shown), in this way, the holes of the shape of the two sets of punching plates 1005 can complete the punching of the copper busbar holes of the corresponding shape. When the two sets of punching plates 1005 are fitted together, since the tooth plate 802 will be out of contact with the gear 1008, the tooth plate 802 will not drive the gear 1008 to rotate when it continues to move downward, so that the two sets of punching plates 1005 are just fitted together. After the two sets of punching plates 1005 are fitted together, the puncher 5 has not yet contacted the copper busbar, so the tooth plate 802 will continue to move downward for a distance (as long as the thickness of the copper busbar to be punched is less than the distance that the tooth plate 802 continues to move, the punching of the copper busbar can be completed), and 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 card shell 805 to enter When the positive and negative screw rods 1007 are moved upward, the positive and negative screw rods 1007 will rotate in the other direction and the two sets of punching plates 1005 will be opened to both sides. When the positive and negative screw rods 1007 are rotating, the two sets of screw sleeves 907 will drive the rotating wheels 909 to move synchronously in the opposite directions. When the rotating wheels 909 move, they will drive the telescopic shell 913 to stretch. The telescopic shell 913 can protect the positive and negative screw rods 1007, which can prevent the waste material punched down from the surface of the copper bar from damaging the positive and negative screw rods 1007. When the rotating wheels 909 move to a certain distance, the second friction wheel 908 on the surface of one set of rotating wheels 909 will contact the first friction wheel 904. As the motor 901 (permanent magnet synchronous motor 901, the output end is a hollow shaft, and the hollow shaft has an independent sealing structure inside, so it is sealed. The sealing structure does not rotate with the hollow shaft) and drives the rotation of the rotating shell 903 (connected to one end of the hollow shaft) and the first friction wheel 904, which will drive the second friction wheel 908 and the rotating wheel 909 to rotate, and because the forward and reverse screw rods 1007 drive the screw sleeve 907 to move back and forth continuously, the rotating wheel 909 will be driven 72 degrees by the motor 901 at the moment when the second friction wheel 908 contacts the first friction wheel 904, thereby driving the telescopic shell 913 to rotate 72 degrees, which can prevent the waste from always hitting the same position on the surface of the telescopic shell 913 and causing the telescopic shell 913 to be quickly damaged. When the telescopic shell 913 and the rotating wheel 909 rotate, the positioning plate 910 will be driven to rotate, and the positioning hole 911 will be aligned with the piston end of the first spring push rod 912. The first spring push rod 912 is squeezed. Since the piston end of the first spring push rod 912 is made of tempered glass, it will retract when squeezed 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, which are just enough for the first spring push rod 912 to be positioned five times. In this way, the telescopic shell 913 after rotation is fixed. Since it has been working all day, the reciprocating movement between the gear 1008 and the tooth plate 802 is as high as 10,000 to 20,000 times. Since the lubricating oil between the tooth plate 802 and the gear 1008 will be consumed very quickly, the operation of the device can be stopped (the tooth plate 802 will be above the gear 1008 at this time), and then the handle 806 is rotated.The rotating of the rotating handle 806 drives the rotating of the one-way screw rod 804, the rotating of the one-way screw rod 804 drives the upward movement of the toothed plate 802, the upward movement of the toothed plate 802 drives the synchronous upward movement of the push rod 803, in the process of the upward movement, the push rod 803 pushes the limiting plate 807 to move out of the inside of the push plate 808, at this time, the gap between the teeth of the toothed plate 802 is located at one end of the four injectors 809, then the push plate 808 is pushed, the push plate 808 drives the movement of the injectors 809, when the front end of the injectors 809 is located in the gap between the teeth, the baffle 811 is blocked by the connecting block 812, then the push plate 808 is pushed, the lubricating oil in the injectors 809 is accurately injected between the teeth, this injection mode of the lubricating oil not only saves time and effort, but also effectively controls the amount to prevent the waste of the lubricating oil, the lubricating oil in one set of the injectors 809 can be used for many times, and when the lubricating oil in the injectors 809 is used up, the piston end of the injectors 809 can be pulled out of the injection port 810, and the inside of the injectors 809 is supplemented with the lubricating oil.

[0034] It should be noted that: the parts have a life cycle, and can be replaced during regular maintenance when the use performance cannot be reached in the later period, the long-time use of the parts leads to the poor use effect, which does not belong to the design defects of the application.

[0035] The embodiment is only an explanation of the application, and is not a limitation of the application, and the person skilled in the art can make the modification of the embodiment without the creative contribution according to the need after reading the specification, as long as the modification is within the scope of the claims of the application and is protected by the patent law.
