Description

Technical Field

[0001] The present application relates to the technical field of copper busbar processing equipment, and in particular to a punching device for integrated copper busbar processing. Background Art

[0002] As an important conductive material, copper busbars are widely used in the fields of electricity and electrical engineering. In the production and processing of copper busbars, punching, cutting and polishing are common processes. In the prior art, punching and cutting machines have appeared, but polishing still requires manual operation.

[0003] Therefore, in actual use, the staff needs to first place the copper bar on the feed end of the punching and cutting machine (also known as CNC idle punching and shearing machine), and use the punching and cutting machine to automatically punch and cut the copper bar to form several copper bars. Finally, the staff uses a handheld polishing machine to polish the edges of each formed copper bar to remove burrs, surface stains, etc.

[0004] When this method is used, generally only one worker is required to configure one device. However, each time a copper bar is processed, the worker needs to polish each copper bar before loading a new copper bar, which restricts the production efficiency of the copper bar.

[0005] Alternatively, one worker may be responsible for loading and carrying the cut and formed copper bars, and then multiple workers may be responsible for the subsequent polishing work, but this will result in excessively high labor costs.

[0006] With the continuous development of industrial automation technology, the demand for improving production efficiency, reducing labor costs and ensuring processing quality is becoming increasingly urgent. Therefore, it is particularly important to develop an automated copper busbar processing device that can integrate punching, cutting and polishing functions. Summary of the invention

[0007] The purpose of the present application is to provide a punching device for integrated copper busbar processing, which can integrate punching, cutting and polishing functions to achieve the beneficial effect of reducing costs and increasing efficiency.

[0008] The punching device for integrated copper busbar processing provided in this application adopts the following technical solution: The punching device for integrated processing comprises a punching and cutting machine body, wherein a feed end and a discharge end are respectively arranged on both sides of the punching and cutting machine body, and further comprises two polishing mechanisms, wherein the two polishing mechanisms are respectively located on the upper and lower sides of the discharge end, and each of the polishing mechanisms comprises a lifting mechanism, a driving assembly and a polishing belt, wherein the driving assembly is installed on the lifting mechanism, and the lifting mechanism is used to drive the driving assembly to a working height, wherein one end of the polishing belt is sleeved on the driving assembly, and the other end of the polishing belt can be sleeved on a copper bar, and the driving assembly can control the high-speed transmission of the polishing belt.

[0009] By adopting the above technical solution, when using, the staff only needs to put the copper bar into the punching and cutting machine body through the feed end, and then punch and cut the copper bar through the punching and cutting machine body. When the initially cut copper bar is output from the discharge end, two polishing mechanisms are used to grind and polish the upper and lower sides of the copper bar respectively to achieve the effect of removing burrs. When polishing the copper bar, the lifting mechanism is used to drive the driving component to move away from the copper bar, so that the two ends of the polishing belt are tightly connected to the driving component and the copper bar respectively, and then the driving component drives the polishing belt to drive, so as to achieve the effect of controlling the polishing belt to polish the surface of the copper bar.

[0010] Optionally, the lifting mechanism is configured as a first rodless cylinder, a mounting seat is fixed on a slide seat of the rodless cylinder, and the driving assembly is mounted on the mounting seat.

[0011] By adopting the above technical solution, the rodless cylinder has low cost and is easy to use, and the mounting seat arranged on the rodless cylinder can be used to support the driving component.

[0012] Optionally, the driving assembly includes a motor, a driving wheel and a pressure wheel, the motor is arranged on a mounting seat, the driving wheel is mounted on the output shaft of the motor, the pressure wheel is provided with two pieces and is respectively arranged on both sides of the driving wheel, the two pressure wheels are rotatably connected to the mounting seat, the polishing belt is sleeved on the driving wheel, and the outer side of the polishing belt is in contact with the two pressure wheels.

[0013] By adopting the above technical solution, the motor is used to drive the driving wheel to rotate, so as to achieve the pulling transmission of the tensioned polishing belt, and the polishing belt can be clamped by the clamping wheel and the driving wheel.

[0014] Optionally, two annular limiting portions are provided on the outer surface of the driving wheel, and the two annular limiting portions are respectively provided on both sides of the driving wheel. When the polishing belt is sleeved on the driving wheel, the polishing belt is located between the two annular limiting portions.

[0015] By adopting the above technical solution, the annular limiting portion can be used to limit the position of the polishing belt, thereby preventing the polishing belt from detaching from the driving wheel when the driving wheel rotates at a high speed, thereby ensuring the safe use of the polishing belt.

[0016] Optionally, the mounting seat is arranged in an "L" shape, the horizontally arranged part of the mounting seat is located on the side of the motor away from the copper discharge material position, the motor is installed on the horizontally arranged part of the mounting seat, a slide groove is vertically arranged on the vertically arranged part of the mounting seat, a slider is slidably connected in the slide groove, the clamping wheel is installed on the slider, and a spring is arranged between the slider and the horizontally arranged part of the mounting seat, and the spring is used to apply a force to the slider to move toward the direction of the motor.

[0017] By adopting the above technical solution, the spring can always apply a force toward the driving wheel to the slider, so that the slider can drive the clamping wheel to move toward the driving wheel, ensuring that the clamping wheel can cooperate with the driving wheel to clamp the polishing belt.

[0018] Optionally, it also includes a protective cover, which is installed on the discharge end by means of bolt locking, and covers two polishing mechanisms. The protective cover is provided with an outlet for the output of the copper busbar, and the side of the protective cover connected to the storage end is open, and a transparent observation port is provided on one side of the protective cover.

[0019] By adopting the above technical solution, when the copper bar is polished by the polishing belt, some polishing dust will be generated. The protective cover can intercept the polishing dust and prevent foreign matter from entering between the polishing belt and the copper belt, thereby ensuring the safe use of the polishing belt. The transparent observation port provided on the protective cover can facilitate the staff to observe the real-time polishing condition of the copper belt.

[0020] Optionally, it also includes a hook-pull mechanism, which includes a slide rail, a second telescopic cylinder and a hook rod, the slide rail is installed in a protective cover, the upper end of the hook rod is slidably connected to the slide rail through a sliding seat, the second telescopic cylinder is installed in the protective cover to drive the hook rod to rise and fall, and a hook body is provided at the lower end of the hook rod, and the hook body is used to pull up the polishing belt that can press the upper surface of the copper busbar.

[0021] By adopting the above technical solution, when a copper belt is polished, the upper end of the polishing belt used to polish the upper surface of the copper bar lacks support and may fall directly, which is not conducive to the next polishing action. Therefore, by utilizing the cooperation between the second telescopic cylinder and the slide rail, the hook rod can be driven up and down to hook up the fallen polishing belt, so as to facilitate the new copper belt to pass through the polishing belt for the next polishing process.

[0022] Optionally, the two polishing mechanisms are arranged along the moving direction of the copper bar, the hook rod includes two extension rods parallel to each other, the upper ends of the two extension rods are connected to the hook rod as a whole, and the hook body is formed by horizontally bending the lower ends of the two extension rods toward the direction of the discharge end. The copper bar can pass through between the two extension rods, and when the polishing belt is tightened in cooperation with the hook rod, the hook body is located within the enclosed range of the polishing belt.

[0023] By adopting the above technical solution, the hook body is used to hook the polishing belt, and the extension rod is used to avoid the copper belt, so as to avoid interference with the copper belt when the hook rod is raised and lowered to adjust the top position of the polishing belt, thereby ensuring the safe use of the hook rod.

[0024] Optionally, an exhaust fan is further provided on the protective cover, an air inlet of the exhaust fan is communicated with the interior of the protective cover, and a dust filter is installed on the air outlet of the exhaust fan.

[0025] By adopting the above technical solution, the exhaust fan can extract the polishing dust generated during the polishing process, avoid excessive accumulation of polishing dust in the protective cover, and further ensure safety in use.
