Description

TECHNICAL FIELD

[0001] The application relates to the technical field of copper bar heat dissipation plates, in particular to a straightening device for a copper bar. BACKGROUND

[0002] Copper bar heat dissipation refers to a heat dissipation mode that uses copper bars as heat conduction and dissipation media to conduct and dissipate the heat generated by equipment or components. It is widely used in the fields of power systems, electronic equipment, industrial machinery, etc., to ensure that the equipment operates stably at a safe temperature and prevents overheating damage or performance degradation. Copper bar heat dissipation mainly relies on the high thermal conductivity of copper to conduct heat from the heat source to the copper bar, and then transfer the heat to the surrounding environment through convection, radiation, etc. The shape and structure design of the copper bar can increase the heat dissipation area and improve the efficiency. In some high-power equipment, copper bar heat dissipation is often combined with other heat dissipation technologies such as heat pipes and fans to meet higher heat dissipation requirements.

[0003] In the copper bar straightening device, lubricating oil plays a crucial role. If there is a lack of lubricating oil, the copper bar directly contacts and rubs against the guide plates and other components of the straightening device, the friction coefficient increases, the metal surface is quickly worn out, scratches and dents are generated, and the service life of the equipment is shortened. SUMMARY

[0004] The purpose of the present application is to provide a straightening device for a copper bar to solve the above problems. The oil dripping structure and the smearing structure are adopted, and the lubricating oil is smeared on the straightening plate before straightening. The existence of the oil film changes the friction between the copper bar and the device components from dry friction to internal friction of the oil film, greatly reduces the friction coefficient, and reduces the friction heat and mechanical wear caused by direct contact.

[0005] The application achieves the above-mentioned purposes through the following technical solutions:

[0006] A straightening device for a copper bar, comprising:

[0007] An upper guide plate and a lower guide plate, which are in a flat structure distributed in an upper and lower manner, and the upper guide plate is connected with a driving assembly capable of driving it to lift and lower;

[0008] A lubricating assembly, comprising an oil storage box arranged above the lower guide plate, a stand connected with the oil storage box, and a plurality of conical oil dripping heads arranged at the bottom of the oil storage box, two parallel arranged sliding rods, a sliding block sleeved with the sliding rods, and a lug connecting the sliding block with the lower guide plate;

[0009] A flow regulating mechanism, comprising a threaded support fixedly connected with the top of the oil storage box, a screw threadedly connected with the threaded support, a lifting rod connected with the bottom end of the screw, and a plug arranged at the bottom of the lifting rod corresponding to the oil dripping head;

[0010] The application assembly includes a brush sleeve mounted on a column, a brush strip that can be slidably inserted into the brush sleeve, and brush bristles located at the bottom end of the brush strip.

[0011] Furthermore, the bottom of the lower guide plate is connected to an oil drain pipe, and its four sides are provided with upward-extending baffles.

[0012] Furthermore, the flow regulating mechanism also includes sliding columns fixed inside the oil storage box, which are symmetrically distributed on both sides of the lifting rod and slide in cooperation with it.

[0017] Compared with the prior art, this application adopts a conical oil dripping head structure and a brush-like coating structure. Before straightening, lubricating oil is applied to the straightening plate. The presence of the oil film changes the friction between the copper busbar and the device components from dry friction to internal friction of the oil film, which greatly reduces the coefficient of friction and reduces frictional heat and mechanical wear caused by direct contact.

[0027] like Figures 1-4 As shown, a straightening device for copper busbars includes:

[0028] The upper guide plate 1 and the lower guide plate 2 are flat plate structures distributed vertically. The upper guide plate 1 is connected to a drive component that can drive it to rise and fall.

[0029] The lubrication assembly includes an oil reservoir 3 located above the lower guide plate 2, a column 20 connecting the oil reservoir 3, multiple conical oil drip heads 6 located at the bottom of the oil reservoir 3, two parallel sliding rods 18, a slider 19 sleeved on the sliding rods 18, and a lug 17 connecting the slider 19 and the lower guide plate 2.

[0030] The flow regulating mechanism includes a threaded support 9 fixedly connected to the top of the oil storage box 3, a screw 11 threadedly connected to the threaded support 9, a lifting rod 7 connected to the bottom of the screw 11, and a plug 8 provided at the bottom of the lifting rod 7 corresponding to the drip head 6.

[0031] The application assembly includes a brush sleeve 16 mounted on a column 20, a brush strip 4 slidably inserted into the brush sleeve 16, and brush bristles 5 mounted at the bottom of the brush strip 4.

[0032] Specifically, the oil storage box 3 is a hollow structure with an open top, which can store lubricating oil. The oil drip head 6 has an oil outlet at the bottom. The plug 8 is adapted to the conical oil drip head 6. When the plug 8 is in contact with the oil drip head 6, it can close the oil passage. The height of the plug 8 can be adjusted to adjust the amount of oil dripped from the oil drip head 6. The slide bar 18 supports the sliding of the slider 19 to adjust the position of the bristles 5.

[0033] Furthermore, the bottom of the lower guide plate 2 is connected to an oil drain pipe 21, and its four sides are provided with upwardly extending baffles 14.

[0034] Furthermore, the flow regulation mechanism also includes a sliding column 13 fixed inside the oil storage box 3. The sliding column 13 is symmetrically distributed on both sides of the lifting rod 7 and slides with it.

[0035] Furthermore, the top end of the screw 11 is provided with a rotating handle 12, and the bottom end is rotatably connected to the lifting rod 7 through a bearing.

[0036] Specifically, turning the handle 12 causes the screw 11 to rotate, and the screw 11 moves up and down on the threaded support 9 to drive the lifting rod 7 to move up and down, thereby adjusting the height of the plug 8 to adjust the amount of oil dripping from the oil dripping head 6.

[0037] Furthermore, the brush sleeves 16 are symmetrically arranged on both sides of the oil drip head 6, and brush clearance grooves 15 are provided on the corresponding columns 20.

[0038] Specifically, the brush strip 4 can be pulled out or inserted from the inside of the brush sleeve 16 for easy maintenance of the bristles 5.

[0039] Furthermore, the plug 8 is a tapered rubber head, the taper of which is adapted to the taper of the inner cavity of the drip head 6.

[0041] Specifically, the lower guide plate 2 can contact the upper guide plate 1 through the drive of the hydraulic cylinder 24, and can squeeze the copper busbar placed on the upper guide plate 1 to straighten the copper busbar.

[0042] In the above structure, before the straightening work, lubricating oil is added to the oil reservoir 3, and the height of the lifting rod 7 is adjusted so that the plug 8 can open and close the drip head 6. After the channel of the drip head 6 is opened, the lubricating oil drips from the brush bristles 5 onto the lower guide plate 2. Through the sweeping of the brush bristles 5, the lubricating oil is evenly applied to the lower guide plate 2. Then, the upper guide plate 1 is driven to descend and contact the lower guide plate 2. The lubricating oil is adsorbed on the upper guide plate 1. The copper busbar to be straightened is placed between the upper guide plate 1 and the lower guide plate 2. The upper guide plate 1 is driven to descend, pressing the bent copper busbar into a flat plate shape. During this process, the lubricating oil can lubricate the copper busbar and reduce the wear of the copper busbar.
