Description

Technical Field

[0001] The utility model relates to the field of copper bar production equipment, in particular to a hydraulic cold drawing machine for copper bar production. Background Art

[0002] Copper busbar, also known as copper busbar or copper busbar, is made of copper with a rectangular or chamfered cross-section. It plays the role of transmitting current and connecting electrical equipment in the circuit. Copper busbar needs to be cold-drawn during the production process.

[0003] After searching, the Chinese patent announcement number CN212168547U discloses a drawing machine for copper bar production, which includes a frame, a drawing mechanism and a mold assembly are fixed on the top of the frame; the mold assembly includes a fixed block, a first groove and a through groove are opened on the fixed block, a first clamping block is placed inside the first groove, a second groove and a third groove are opened on the top of the first clamping block, a mold body is placed inside the second groove, a second clamping block is fixed outside the mold body, and the second clamping block is arranged inside the third groove, and a fixed plate is fixed on the front side of the fixed block. The device drives the first clamping block on it to escape from the first groove by pulling the handle, and then the mold body can be pulled out upward and the mold body can be removed and replaced. The operation is simple and convenient, which greatly facilitates the later maintenance. After the mold body is installed, the limiting fixing effect is very good, which improves the stability during the drawing process. However, during the use of the device, when feeding through the coil drum, as the processing and production proceed, the diameter of the coil drum changes from large to small, resulting in a change in the feeding angle of the material roll, which affects the cold drawing forming effect of the mold assembly on the copper roll, and the practicality needs to be enhanced. Utility Model Content

[0004] The purpose of the utility model is to provide a hydraulic cold drawing machine for copper bar production in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A hydraulic cold drawing machine for copper bar production comprises a supporting mechanism, a cold drawing machine body is mounted on the supporting mechanism, a feeding mechanism is arranged on the front side of the top of the supporting mechanism, a guiding mechanism is arranged at the middle position of the top of the supporting mechanism, a positioning mechanism is arranged in the guiding mechanism, the guiding mechanism comprises a mounting table, two guiding rollers are rotatably mounted in the mounting table, a drawing frame is slidably connected in the mounting table, the positioning mechanism comprises a rocker, a bidirectional screw rod is fixedly connected to the bottom of the rocker, and a positioning block matching the guide roller is fixedly connected in the middle position of the bidirectional screw rod.

[0007] Preferably, a through hole is opened at the top of the pull-out frame, a plug is clamped in the through hole, and the plug is slidably connected to the top of the mounting platform.

[0008] Preferably, two pressing plates are threadedly connected to the side of the bidirectional screw rod, baffles are fixedly connected to the opposite surfaces of the two pressing plates, and a sliding rod is slidably connected to one end of the pressing plate away from the bidirectional screw rod.

[0011] Preferably, the cold drawing machine body is arranged at the rear end of the base and the top of the extension platform, a mold is arranged on the inner side of the pressing plate, and the guide roller, the mold and the cold drawing machine body are matched.

[0012] The beneficial effect is that a guiding mechanism and a positioning mechanism are set. During the copper busbar production process, the diameter of the copper material coil will become smaller and smaller, resulting in a change in the conveying direction, which affects the forming effect. By setting guide rollers and positioning blocks, the copper material coil is guided so that the mold and the two guide rollers are always aligned, and the guide rollers play a good guiding role, thereby ensuring the cold drawing effect and improving the production quality of the copper busbar.

[0027] In this embodiment, the feeding mechanism 3 includes two vertical poles 301, a placement groove 302 is opened in the vertical pole 301, a rotating rod 303 is placed in the placement groove 302, both ends of the rotating rod 303 are connected to the limiting blocks 304 by bolts, a copper coil 305 is sleeved on the rotating rod 303, and the limiting blocks 304 are against both sides of the vertical pole 301 to prevent the copper coil 305 from shaking left and right when feeding, thereby ensuring stable feeding.

[0028] In this embodiment, the guide mechanism 4 includes a mounting table 401, in which two guide rollers 402 are rotatably installed, a pull-out frame 403 is slidably connected inside the mounting table 401, a through hole 404 is opened on the top of the pull-out frame 403, a plug 405 is clamped in the through hole 404, the plug 405 is slidably connected to the top of the mounting table 401, the plug 405 is an inverted L-shape, and the plug 405 clamps the pull-out frame 403 in the mounting table 401 to prevent shaking during cold drawing and affect the forming quality.

[0029] In this embodiment, the positioning mechanism 5 includes a rocker 501, a bidirectional screw rod 502 is welded at the bottom of the rocker 501, a positioning block 503 matched with the guide roller 402 is welded in the middle position of the bidirectional screw rod 502, two pressing plates 504 are threadedly connected to the side of the bidirectional screw rod 502, and baffles 505 are connected to the opposite surfaces of the two pressing plates 504 by bolts. The end of the pressing plate 504 away from the bidirectional screw rod 502 is slidably connected with a sliding rod 506, and a mold 507 is arranged on the inner side of the pressing plate 504. The guide roller 402 and the mold 507 are matched with the cold drawing machine body 2. When the cold drawing machine body 2 is cold drawn, due to the setting of the positioning block 503, the mold 507 can be aligned with the middle position of the two guide rollers 402, ensuring that the copper material is transported horizontally during movement, and the forming effect is good.

[0030] Working principle: When the device is in use, the rotating rod 303 with the copper coil 305 wound around it is placed in the placement groove 302, and the limit blocks 304 are against the two sides of the vertical rod 301. In the initial state, the pull-out frame 403 is separated from the mounting platform 401, and the copper coil 305 is passed between the guide rollers 402. Then, the end of the copper coil 305 pulled out is processed into a shape that adapts to the mold 507, and then it is passed through the mold 507, and the mold 507 is placed in the mounting platform 401. Then, the pull-out frame 403 is inserted from the top of the mounting platform 401, and the mold 507 and the copper coil 305 are moved through the inner side of the pull-out frame 403, and the mold 507 is placed between the two pressing plates 504. Then, the rocker 501 is rotated, and the rocker 501 drives the bidirectional screw rod 502 to rotate, and the bidirectional screw rod 502 drives The two pressing plates 504 approach the baffle 505 together, and finally fix the mold 507 in front of the baffle 505. Finally, one end of the copper coil 305 is passed into the cold drawing machine body 2 to complete the installation work, and the plug 405 is inserted into the through hole 404 to prevent shaking during cold drawing and affecting the forming quality. The cold drawing machine body 2 is turned on, and the cold drawing machine body 2 cold draws the copper coil 305. The baffle 505 prevents the mold 507 from shaking. During the feeding process of the copper coil 305, the diameter of the copper coil 305 changes from large to small. Due to the setting of the guide roller 402 and the positioning block 503, the guide roller 402 guides the copper coil 305 on the front side, and the mold 507 can be aligned with the middle position of the two guide rollers 402 to ensure that the copper material is transported horizontally during movement, and the forming effect is good.
