Description

Technical Field

[0001] This utility model relates to the field of copper processing technology, specifically a pretreatment device for stretching copper materials. Background Technology

[0002] Stretching is a pressure processing method that changes the shape and size of a blank by passing it through a die and applying tensile force. It is a key process in the production of finished copper rods and wires, and is mainly used in electronics, electrical appliances, communications, and construction. Copper has advantages such as good electrical and thermal conductivity and strong corrosion resistance, and therefore is widely used in various fields. Before stretching copper, it is essential to ensure that the copper surface is smooth, free of scratches, and has few impurities; secondly, pretreatment of the copper is necessary, including cleaning and degreasing.

[0003] A pretreatment device for stretching copper material, disclosed in Chinese Patent Publication No. CN215198993U, comprises: a base with a movable guide rail; a first engagement component for clamping the head of the copper material and adapted to the movable guide rail; a second engagement component fixedly connected to the base and coaxially configured with the first engagement component for clamping the downstream segment of the copper material head; and a driving member for driving the first engagement component to move along the movable guide rail. The first engagement component is configured to move closer to or further away from the second engagement component along the movable guide rail via the driving member. When the first engagement component clamps the head of the copper material and moves along the movable guide rail away from the second engagement component, the length of the clamped portion of the copper material increases and the radial dimension decreases, thereby achieving the purpose of correcting the head of the copper material.

[0004] The above solution still has at least the following defects in actual operation: the device does not clean and degrease the surface of the strip copper material, which can easily cause foreign objects on the surface of the strip copper material to scratch the surface of the strip copper material when it is stretched, affecting the stretching quality of the strip copper material.

The two first sprockets 6 are respectively fixedly sleeved on the front ends of the two first rotating shafts 4. The first chain 7 is wound around the two first sprockets 6. The feeding mechanism utilizes the combined action of two first sprockets 6 and a first chain 7 to enable the two support rollers 5 to rotate at the same speed and in the same direction.

The feeding mechanism also includes an electric push rod 9, a U-shaped plate 10, two second rotating shafts 11, two clamping rollers 12, two second sprockets 13, a second chain 14, and a second motor 15. The electric push rod 9 is fixedly mounted on the top inner wall of the support frame 2, and the U-shaped plate 10 is fixedly mounted on the output shaft end of the electric push rod 9. Both second rotating shafts 11 are rotatably mounted on the U-shaped plate 10. Two clamping rollers 12 are respectively fixedly sleeved on the two second rotating shafts 11. Annular clamping grooves 38 are provided on both support rollers 5 and the two clamping rollers 12. All four annular clamping grooves 38 are at a 90-degree angle. By utilizing the four annular clamping grooves 38, copper materials of various shapes such as square and round can be easily clamped. The front ends of both second rotating shafts 11 extend beyond the U-shaped plate 10. Two second sprockets 13 are respectively fixedly sleeved on the front ends of the two second rotating shafts 11. Second chains 14 are wound around the two... On the second sprocket 13, by utilizing the combined action of the two second sprockets 13 and the second chain 14, the two clamping rollers 12 can rotate at the same speed and in the same direction. The second motor 15 is fixedly installed on the front side of the U-shaped plate 10, and the output shaft end of the second motor 15 is fixedly connected to the front end of one of the second rotating shafts 11. It should be noted that both the first motor 8 and the second motor 15 are forward and reverse rotating motors, and the first motor 8 and the second motor 15 have the same model, the same power, and opposite directions. Specifically, the first motor 8 rotates clockwise, and the second motor 15 rotates counterclockwise (with the first motor 8 rotating clockwise and the second motor 15 rotating counterclockwise). Figure 2 (Observation from a different perspective).

[0026] In this embodiment, a control switch is installed on the workbench 1. The first motor 8, the second motor 15, the water pump 17, the third motor 31 and the control switch are electrically connected to the external power supply line in sequence through wires to form a circuit. The control switch can control the start and stop of the first motor 8, the second motor 15, the water pump 17 and the third motor 31 respectively.

[0027] With the above structure, the pretreatment device for copper stretching provided by this utility model can clamp copper strips of various sizes and control the copper strips to move automatically to the left to clean the oil stains on the surface of the copper strips. During cleaning, the annular brush 26 is used to brush the surface of the copper strips back and forth, and after brushing, the copper strips are rinsed again, improving the cleaning efficiency and quality of the copper strips. In specific use, the copper strips to be cleaned are placed in the annular clamping grooves 38 on the two support rollers 5, and the electric push is controlled. When rod 9 extends, the electric actuator 9 controls the two clamping rollers 12 to move downwards to clamp and fix the strip copper material. It also controls the operation of the first motor 8 and the second motor 15. The first motor 8 begins to rotate clockwise, and the second motor 15 begins to rotate counterclockwise. By utilizing the combined action of the two first sprockets 6 and the first chain 7, the two support rollers 5 can rotate clockwise at the same speed. By utilizing the combined action of the two second sprockets 13 and the second chain 14, the two clamping rollers 12 can rotate counterclockwise at the same speed, thereby controlling the strip copper material to automatically move to the left. The feeding mechanism controls the operation of the third motor 31 and the water pump 17. The third motor 31 drives the disc 32 and the actuating block 33 to rotate, causing the actuating block 33 to periodically push the fixed block 34 to the right. The fixed block 34 drives the sleeve 25 and the two sliding rods 24 to move to the right and compress the two springs 29. When the actuating block 33 disengages from the fixed block 34 due to rotation, the fixed block 34 returns to its initial position under the push of the two springs 29, thereby controlling the sleeve 25 and the annular brush 26 to reciprocate left and right. When the left end of the strip copper material enters the annular brush... After the brush 26 moves within its range, the annular brush 26 begins to scrub the surface of the strip copper material back and forth. At the same time, the water pump 17 draws cleaning fluid from the water tank 16 to rinse the oil stains on the surface of the strip copper material, improving the cleaning efficiency of the copper material. As the feeding mechanism continues to operate, the left end of the strip copper material moves to below the arc-shaped nozzle 36. The high-pressure water flow delivered by the water pump 17 is sprayed onto the surface of the strip copper material through the second diversion pipe 37 and the arc-shaped nozzle 36, rinsing the strip copper material again and further improving the cleaning quality of the strip copper material.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
