Description

Technical Field

[0001] This utility model belongs to the field of copper flat wire processing technology, and in particular relates to a copper flat wire cold welding preforming equipment. Background Technology

[0002] Copper flat wire is a flat metal wire made of copper, typically in the form of a copper rod or bar. Before the cold welding process, these raw materials undergo extrusion pre-forming to precisely control the size and shape of the copper flat wire, ensuring a tighter and more uniform bond during the subsequent cold welding process.

[0003] Patent CN218191771U discloses a novel copper flat wire extrusion machine, which includes an outer frame with an end plate at the front end and a support frame at the rear end of the end plate. While this patent allows for the adaptation of different copper flat wire extrusion requirements by replacing the first or second pressure roller, the operation is relatively cumbersome. Specifically, it requires rotating the turntable, disassembling the screw, gripping the baffle, and removing the second drive shaft to successfully replace the first or second pressure roller. After replacement, the positions of the first and second drive shafts must be calibrated, the turntable rotated again, and the screw driven in. This series of cumbersome steps not only increases the operation time but also raises the operational difficulty.

[0004] Therefore, there is a particular need for a cold-welding preforming equipment for copper flat wires to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents, such as complicated operation steps, long time consumption and high operation difficulty when replacing the No. 1 or No. 2 pressure roller, this utility model provides a copper flat wire cold welding preforming equipment.

[0006] This utility model is achieved through the following technical means: a copper flat wire cold welding preforming equipment, including a frame, a mounting cover, a first motor, a winding wheel, a sliding frame, a first extrusion roller, a second extrusion roller, a drive assembly, and an adjustment assembly. The mounting cover is fixed to the upper rear side of the frame. The first motor is installed at the center point of the right side of the mounting cover. The winding wheel is rotatably connected inside the mounting cover. The output shaft of the first motor faces left and passes through the mounting cover, being fixedly connected to the right end of the winding wheel. The sliding frame is slidably connected to the front of the frame, and the front end of the track for the sliding frame to slide on the frame has a closed design and the track is of the same size. The first and second extrusion rollers are distributed vertically and are both located on the upper part of the sliding frame. The first extrusion roller is rotatably engaged with the sliding frame, while the second extrusion roller is rotatably and slidably engaged with the sliding frame and is located at the lowest point of the sliding area on the sliding frame. A drive assembly for driving the first and second extrusion rollers to rotate is located between the sliding frame, the first extrusion roller, and the second extrusion roller. An adjustment assembly for adjusting the tension of the raw material is located on the mounting cover. The system also includes an adjustment assembly for adjusting the height of the second extrusion roller, located between the sliding frame and the second extrusion roller.

[0007] Preferably, the drive assembly includes a second motor, a third motor, and a universal joint. The second motor is mounted on the upper right side of the sliding frame, with its output shaft facing left and fixedly connected to the right end of the first extrusion roller. The third motor is mounted on the upper left side of the sliding frame, with its output shaft facing right and rotatably connected to the left end of the second extrusion roller via a universal joint.

[0008] Preferably, the adjusting assembly includes a screw and a guide rod. The screw is rotatably connected to the upper right side of the sliding frame, and its uppermost end extends to the outside of the sliding frame. The right end of the second extrusion roller is threadedly engaged with the screw. The guide rod is fixed to the upper left side of the sliding frame, and the left end of the second extrusion roller is slidably engaged with the guide rod. The uppermost end of the guide rod extends to the outside of the sliding frame.

[0009] Preferably, the adjustment assembly includes a support frame, a sliding arm, a slide rail, a slider, a clamping block, and a spring. Two support frames are symmetrically distributed and fixed to the center of the front of the mounting cover. Each sliding arm is slidably connected to each support frame. The slide rail is fixed between the front of the two sliding arms. The slider is slidably connected to the slide rail. Two clamping blocks are distributed vertically and slidably connected inside the slider. Two springs are aligned laterally as a group, and there are two groups in total. Each group of springs is fixed between the slider and the corresponding clamping block. The front and rear ends of the clamping block have an inclined structure.

[0010] Preferably, the device also includes a fourth motor, a grooved wheel, and a slide bar. The fourth motor is installed at the front of the right sliding arm. The grooved wheel is rotatably connected between the two sliding arms and has two threaded grooves with opposite spiral directions on its surface. The output shaft of the fourth motor faces left and is fixedly connected to the right end of the grooved wheel. The slide bar is fixedly connected to the bottom end of the slider and is threadedly engaged with the grooved wheel.

[0011] Preferably, a protective layer is provided on the clamping surface of the clamping block.

[0012] The beneficial effects of this utility model are:

[0013] By adjusting the component design, the operator can adjust the height of the second extrusion roller via the screw, enabling the equipment to flexibly adapt to the extrusion requirements of different types of copper flat wires. The adjustment process is simple and does not require complicated steps.

[0014] By adjusting the design of the components, the tension of the raw materials can be effectively controlled, ensuring that the raw materials maintain stable tension during extrusion, preventing slippage or loosening of the raw materials, thereby improving the winding quality.

[0015] Through the combined action of the fourth motor, grooved wheel, and slide bar, continuous and uniform traction and winding of the extruded raw material are achieved, further improving the winding quality. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example: A copper flat wire cold welding preforming equipment, such as... Figures 1-4As shown, the assembly includes a frame 1, a mounting cover 2, a first motor 3, a winding wheel 4, a sliding frame 5, a first extrusion roller 7, a second extrusion roller 71, a drive assembly, and an adjustment assembly. The mounting cover 2 is welded to the upper rear side of the frame 1. The first motor 3 is bolted to the center point of the right side of the mounting cover 2. The winding wheel 4 is rotatably connected inside the mounting cover 2 and is a fixed winding wheel with a special fixing mechanism or structure to firmly fix one end of the raw material. The output shaft of the first motor 3 faces left and passes through the mounting cover 2 to be fixedly connected to the right end of the winding wheel 4. The sliding frame 5 is slidably connected to the front of the frame 1, and the front end of the track on the frame 1 for the sliding frame 5 to slide is enclosed to prevent the sliding frame 5 from detaching from the frame 1. The first extrusion roller 7 and the second extrusion roller 71, which are of the same size, are distributed vertically and are both set on the upper part of the sliding frame 5. The first extrusion roller 7 rotates with the sliding frame 5, while the second extrusion roller 71 rotates and slides with the sliding frame 5 and is located at the lowest point of the sliding area on the sliding frame 5, so that the distance between the second extrusion roller 71 and the first extrusion roller 7 is minimized in the initial state. The drive assembly for driving the first extrusion roller 7 and the second extrusion roller 71 to rotate is set between the sliding frame 5, the first extrusion roller 7 and the second extrusion roller 71. The adjustment assembly for adjusting the tension of the raw material is set on the mounting cover 2. The sliding frame 5 is also included. The adjustment assembly for adjusting the height of the second extrusion roller 71 is set between the sliding frame 5 and the second extrusion roller 71.

[0023] like Figure 1 and Figure 2 As shown, the drive assembly includes a second motor 6, a third motor 61, and a universal joint 62. The second motor 6 is bolted to the upper right side of the sliding frame 5, with its output shaft facing left and fixedly connected to the right end of the first extrusion roller 7. The third motor 61 is bolted to the upper left side of the sliding frame 5, with its output shaft facing right and rotatably connected to the left end of the second extrusion roller 71 via the universal joint 62. This rotatable connection is a vertical rotatable connection, ensuring that when the output shaft of the third motor 61 rotates, it normally drives the second extrusion roller 71 to rotate via the universal joint 62.

[0024] like Figure 3 and Figure 4As shown, the adjustment assembly includes a support frame 10, a sliding arm 11, a slide rail 14, a slider 15, a clamping block 17, and a spring 18. Two support frames 10 are symmetrically distributed and connected to the center of the front of the mounting cover 2 by welding. Each sliding arm 11 is slidably connected to each support frame 10. The contact surface between the sliding arm 11 and the corresponding support frame 10 is roughened or covered with a high-friction coefficient material to increase the frictional resistance between the sliding arm 11 and the corresponding support frame 10, ensuring a stable connection between the two and preventing accidental sliding of the sliding arm 11. Each sliding arm 11 has a pull block at its rear end, and each support frame 10 has a square-structured limiting block at its front end, which is located in front of the corresponding pull block. To limit the sliding of the corresponding sliding arm 11 and prevent it from detaching from the corresponding support frame 10, the slide rail 14 is connected between the front parts of the two sliding arms 11 by welding. The slider 15 is slidably connected to the slide rail 14. The two clamping blocks 17 are distributed vertically and slidably connected inside the slider 15. Every two horizontally aligned springs 18 form a group, and there are two groups in total. Each group of springs 18 is connected between the slider 15 and the corresponding clamping block 17 by welding. The front and rear ends of the clamping block 17 have a sloping structure. When the raw material comes into contact with the front end of the clamping block 17, it can be squeezed outward along the sloping surface of the clamping block 17. The clamping surface of the clamping block 17 is provided with a protective layer of rubber material to prevent scratching the raw material.

[0025] like Figure 2 As shown, the adjustment assembly includes a screw 8 and a guide rod 9. The screw 8 is rotatably connected to the upper right side of the sliding frame 5, and its uppermost end extends to the outside of the sliding frame 5. It is equipped with a knob for easy rotation. The right end of the second extrusion roller 71 is threadedly engaged with the screw 8. The guide rod 9 is connected to the upper left side of the sliding frame 5 by welding. The left end of the second extrusion roller 71 is slidably engaged with the guide rod 9, and the uppermost end of the guide rod 9 extends to the outside of the sliding frame 5 to maximize the guiding effect.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a fourth motor 12, a grooved wheel 13, and a sliding rod 16. The fourth motor 12 is bolted to the front of the right sliding arm 11. The grooved wheel 13 is rotatably connected between the two sliding arms 11 and has two threaded grooves with opposite spiral directions on its surface. The output shaft of the fourth motor 12 faces left and is fixedly connected to the right end of the grooved wheel 13. The sliding rod 16 is welded to the bottom of the slider 15 and threadedly engaged with the grooved wheel 13. When the grooved wheel 13 rotates clockwise, the sliding rod 16 first moves to the left along the first thread of the grooved wheel 13. Then, when it reaches the end of the first thread, it smoothly transitions to the second thread of the grooved wheel 13 and moves to the right, allowing the sliding rod 16 to achieve continuous left-right reciprocating motion during the rotation of the grooved wheel 13.

[0027] The operator first rotates the screw 8 clockwise, causing the second extrusion roller 71 to move upward and increase the distance between it and the first extrusion roller 7. During this process, the universal joint 62 continuously connects the second extrusion roller 71 and the output shaft of the third motor 61. Then, a piece of raw material (which has been pre-extruded) is passed through the first extrusion roller 7, the second extrusion roller 71, and the two clamping blocks 17 (the clamping blocks 17 move outward under the pressure of the raw material, and the spring 18 is compressed accordingly), and fixed on the winding wheel 4, completing the initial positioning of the raw material. Then, rotate the screw 8 counterclockwise to cause the second extrusion roller 71 to move downward and close the distance between it and the first extrusion roller 7. When the second extrusion roller 71 moves down to a suitable height and cooperates with the first extrusion roller 7 to press the raw material, stop rotating the screw 8. Then, pull the sliding arm 11 forward to open the distance between the slider 15 and the winding wheel 4. During this process, the two clamping blocks 17 continue to clamp the raw material and adjust the tension of the raw material. When the sliding arm 11 moves forward to a suitable position and the tension of the raw material is in a suitable state, stop pulling the sliding arm 11.

[0028] Then start the first motor 3, the second motor 6 and the third motor 61. The second motor 6 runs, and its output shaft drives the first extrusion roller 7 to rotate clockwise. The third motor 61 runs, and its output shaft drives the second extrusion roller 71 to rotate clockwise through the universal joint 62. It cooperates with the first extrusion roller 7 to extrude the raw material and convey the extruded raw material backward. At this time, the first motor 3 runs, and its output shaft drives the winding wheel 4 to rotate clockwise to start winding the extruded raw material.

[0029] When the first motor 3 and the second motor 6 are started, the fourth motor 12 is started at the same time. Its output shaft drives the grooved wheel 13 to rotate clockwise. During the rotation of the grooved wheel 13, the slide bar 16 first moves to the left along the first thread of the grooved wheel 13. The slider 15 moves to the left with the slide bar 16, pulling the extruded raw material. When the slider 15 moves to the leftmost end of the slide rail 14, the slide bar 16 moves to the leftmost end of the first thread and enters the second thread of the grooved wheel 13. It moves to the right along the second thread. The slider 15 moves to the right with the slide bar 16, continuing to pull the extruded raw material. This process is repeated, with the slider 15 moving back and forth, continuously pulling the extruded raw material to ensure that it is evenly wound on the winding wheel 4.

[0030] Once all the raw materials have been extruded, turn off the first motor 3, the second motor 6, the third motor 61, and the fourth motor 12.

[0031] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
