Description

Technical Field

[0001] The invention relates to the technical field of copper material stretching processing, and in particular to a continuous stretching annealing device for special-shaped copper materials. Background Art

[0002] The drawing operation of special-shaped copper materials (commonly referred to as "special-shaped copper materials") is a key process in metal plastic processing, mainly for precision forming of copper materials with non-standard cross-sectional shapes. The core is to use pulling force to make the copper material pass through a specific die hole, change its cross-sectional shape and size, while ensuring material performance and surface quality.

[0003] Usually, the existing continuous stretching annealing equipment for special-shaped copper materials includes a vertical guide wheel pay-off stand, an eleven-die wire drawing main machine, an AC annealing machine of model TH5000 (which is equipped with a protective cover filled with a protective atmosphere to prevent copper oxidation), a tension control device, and a double-reel wire take-up machine of model 630-2. The wire is paid off by a vertical guide wheel pay-off stand, and the copper material is drawn into copper wire with special-shaped cross-section by the eleven-die wire drawing main machine. The special-shaped copper wire then enters the AC annealing machine for electric annealing, and is finally taken up by the double-reel wire take-up machine. During the whole process, the tension of the copper wire is kept tight by the set tension control device.

[0004] For copper materials with fan-shaped cross-sections, the existing copper continuous drawing annealing equipment has the following problems: The wire drawing die is prone to deflection during the wire drawing process, and the copper material is subjected to additional torque during the wire drawing process, causing the fan angle to deviate from the design value, and the copper material thickness or curvature to be uneven, causing it to exceed the tolerance range; The wire drawing machine will use drawing oil to lubricate and cool the copper material during wire drawing. In order to prevent the drawing oil on the copper material from causing adverse effects on the subsequent electrical annealing (the residual drawing oil decomposes during high-temperature annealing to form carbides attached to the surface of the copper wire, directly affecting the conductivity and appearance. The chloride ions in the oil film react with the copper material to form oxidation spots. At the same time, the residual oil film hinders the uniform transfer of heat, resulting in abnormal grain growth and decreased tensile strength), the copper material will be sprayed with a special cleaning agent (with antioxidant protection ingredients added to the cleaning agent) to remove the oil film before electrical annealing. Before spraying, the cleaning agent needs to be heated to a certain temperature to improve the ability to remove the oil film, which will result in a certain amount of electricity waste. At the same time, spray cleaning is prone to waste a large amount of cleaning agent. Therefore, the present application provides a continuous stretching annealing equipment for special-shaped copper materials to meet the needs. Summary of the invention

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example: Reference Figure 1-2 The shown device is a continuous stretching annealing device for special-shaped copper materials, comprising a wire drawing main machine 1, an AC annealing machine 3, a tension control device 2 and a double-disk wire take-up machine 4. The multiple wire drawing dies 6 of the wire drawing main machine 1 are all provided with fan-shaped wire drawing holes of different specifications. The AC annealing machine 3 is provided with a protective cover 5 filled with a protective atmosphere. The bottoms of the multiple wire drawing dies 6 are all provided with limit blocks 7, and the limit blocks 7 are located in the mounting groove of the mounting block on the inner wall of the wire drawing main machine 1. It also includes a wire drawing oil cleaning unit, which utilizes the high temperature generated during copper drawing to heat the cleaning agent, and then utilizes the heated cleaning agent to soak and clean the copper.

[0021] The limit block 7 is set to ensure the stability of the wire drawing die 6, avoid the copper material rotating during the wire drawing process and causing a large tolerance, and avoid affecting the product quality. At the same time, the high temperature generated during the copper drawing is used to heat the cleaning agent, and then the heated cleaning agent is used to immerse and clean the copper material, so as to make full use of the heat source and save electric energy. Immersion cleaning can save cleaning agent and reduce costs compared with spray flushing.

[0022] As a preferred implementation in this embodiment, Figure 1-5 As shown, the wire drawing oil cleaning unit includes a plurality of first water tanks 8 arranged in a line, each of which has a water storage cavity inside, a second water tank 9 and a third water tank 10; The inner cavities of the multiple first water tanks 8 and the one second water tank 9 are all provided with through holes adapted to the fan-shaped copper material, and the two adjacent first water tanks 8 and the adjacent first water tanks 8 and the second water tanks 9 are connected by connecting pipes 20, and the leftmost first water tank 8 is provided with a liquid inlet pipe, and the multiple first water tanks 8 correspond to the multiple wire drawing dies 6 one by one, and are located on the right side of the corresponding wire drawing dies 6, and the second water tank 9 and the third water tank 10 are both located on the right side of the last wire drawing die 6 in sequence; Side panels 102 are provided on both side ends of the third water tank 10, and the inside of the side panels 102 is hollow and openings are provided on the two side walls, the inner cavities of the two side panels 102 are provided with air bags 103, and the air bags 103 and the third water tank 10 are provided with through holes adapted to the fan-shaped copper material, a weight 104 is provided above the third water tank 10, and support rods are provided at both ends of the weight 104, the lower end of the support rod slides through the corresponding side panel 102 and is connected to the extrusion plate 105, the extrusion plate 105 is tightly attached to the upper end of the corresponding air bag 103, a liquid outlet pipe 101 is provided at the bottom of the inner cavity of the third water tank 10, and the upper end of the liquid outlet pipe 101 is provided close to the top of the inner cavity of the third water tank 10.

[0023] During installation, multiple first water tanks 8 and one second water tank 9 are respectively installed on the right side of the corresponding wire drawing die 6. After each wire drawing of the copper material is completed, the high-temperature copper material will heat the cleaning agent in the water tank through the effect of heat conduction. The number of the first water tanks 8 is set according to the actual temperature required for heating of the cleaning agent. The third water tank 10 is set on the right side of the last group of wire drawing dies 6. The liquid inlet pipe is connected to the pump body, and the input end of the pump body is connected to the tank body of the cleaning agent. After installation, the copper material passes through the through holes on the first water tank 8, the second water tank 9 and the third water tank 10 in turn. At the same time, the two groups of air bags 103 are tightly attached to the outer wall of the copper material through the gravity of the weight 104, and the tight outer wall of the copper material always has a certain gap with the through hole, and the gap can be controlled between 2 and 4 mm (to avoid friction contact with the copper material); During operation, as the copper material moves (at this time, the cleaning agent is injected into the first water tank 8 on the far left through the pump body), the copper material is squeezed and deformed by the wire drawing die 6, and then this part of the copper material generates high temperature. Through the effect of heat conduction, the cleaning agent in the first water tank 8 on the far left is heated. When the inner cavity of the first water tank 8 on the far left is filled, the cleaning agent will overflow into the adjacent first water tank 8 for heating (since multiple first water tanks 8 are provided, the number of first water tanks 8 can be designed according to actual needs, and it is necessary to wait until all the first water tanks 8 are filled with cleaning agent before overflowing into the second water tank 9). After all the first water tanks 8 are filled with cleaning agent , the cleaning agent flows through the second water tank 9 and finally enters the third water tank 10. The cleaning agent is heated layer by layer so that the cleaning agent entering the third water tank 10 reaches the optimal temperature range (the temperature of the special cleaning agent is generally controlled between 50°C and 70°C). The copper material is immersed and cleaned with the cleaning agent of the appropriate temperature range. When the liquid level of the cleaning agent after immersing the copper material rises to the upper end of the liquid outlet pipe 101, the cleaning agent will be discharged outward through the liquid outlet pipe 101, and at the same time, the unreacted cleaning agent will be continuously injected into the third water tank 10, so as to always keep the cleaning agent concentration (and liquid level) in the third water tank 10 stable, which is conducive to the efficient removal of the oil film; The setting of the airbag 103 on the left side can wipe and remove the larger drawing oil on the copper material entering the third water tank 10, so as to reduce the loss of the cleaning agent, and at the same time it is also beneficial to improve the removal effect of the drawing oil on the copper material. After the drawing oil on the copper material is removed, the liquid on the copper material is wiped and removed by the airbag 103 set on the right side to avoid adverse effects on subsequent electrical annealing. The setting of the heavy object 104 can ensure that the airbag 103 always maintains a certain squeezing force with the copper material, which is beneficial to efficiently wipe and remove the drawing oil on it. This structural design can utilize the heat generated by the copper material during wire drawing to heat the cleaning agent layer by layer (absorbing the heat of the copper material after wire drawing, the temperature of the copper material will drop), so that the cleaning agent reaches the most suitable working temperature (the final temperature can be controlled according to the number of first water tanks 8 added), saving electric energy, and also reducing the use of copper coolant. The use of wiping first and then immersing can effectively save the use of cleaning agent and avoid a large amount of waste of cleaning agent.

[0024] It should be noted that the first water tank 8 and the second water tank 9 have the same structure. The first water tank 8 and the second water tank 9 have a heat conducting portion 14 (such as Figure 8 As shown, the long strip structure is located at the axis of the first water tank 8 and the second water tank 9, and its inner surface is arranged opposite to the outer surface of the copper material) is made of heat-conducting material, and the rest are made of heat-insulating material. The third water tank 10 is made of heat-insulating material; third, the connecting pipe 20 is made of heat-insulating material, the fixed end of the telescopic rod 1101 filled with low-boiling-point liquid is made of heat-conducting material, and the movable end of the telescopic rod 1101 is made of heat-insulating material.

[0025] As a preferred implementation in this embodiment, it also includes a temperature self-regulating unit 11, which is used to ensure that the cleaning agent in the third water tank 10 is maintained within a suitable temperature range to improve the treatment effect on the drawing oil film.

[0026] By providing the temperature self-regulating unit 11, it can be ensured that the temperature of the final cleaning agent changes within a reasonable range, which is beneficial to improving the removal effect of the oil film on the copper material.

[0027] As a preferred implementation in this embodiment, Figure 3-5 As shown, the temperature self-regulating unit 11 includes a telescopic rod 1101 filled with a low-boiling-point liquid, an air guide pipe 1102 fixed to the upper end of the third water tank 10, and a fan-shaped strip 91 made of a heat-conducting metal material and slidably disposed in the through hole of the second water tank 9; The upper end of the telescopic rod 1101 is sealed and slidably disposed in the inner cavity of the air guide tube 1102; The inner cavity of the fan-shaped strip 91 is provided with a through hole adapted to the fan-shaped copper material, the upper end of the fan-shaped strip 91 is provided with a T-shaped slide plate 92, and the second water tank 9 is provided with a slide groove adapted to the T-shaped slide plate 92, and a tooth plate 13 is installed on the T-shaped slide plate 92, and the tooth plate 13 is meshed and connected with the transmission gear set 12 installed on the outer wall of the second water tank 9, and the transmission gear set 12 is meshed and connected with the gear rod 1103, and one end of the gear rod 1103 is slidably arranged in the inner cavity of the air guide tube 1102 through an elastic sleeve for sealing (that is, an elastic sleeve is fixed on one end of the gear rod 1103, and the outer wall of the elastic sleeve slides against the inner wall of the air guide tube 1102 to form a seal).

[0028] The telescopic rod 1101 is made of a heat-conducting material, and the boiling point temperature of the low-boiling-point liquid filled in the inner cavity of the telescopic rod 1101 can be controlled to be set at 60°C ± 2°C (taking the alkaline solution containing an anti-oxidation protection component as an example, which is the most suitable constant temperature value for the cleaning agent), and when the temperature self-regulating unit 11 is not set, due to the influence of the ambient temperature, the actual final temperature of the cleaning agent after heating is between 65°C and 74°C; During operation, when the temperature of the cleaning liquid in the third water tank 10 exceeds 60°C ± 2°C, the output end of the telescopic rod 1101 moves upward, squeezing the gas in the air guide tube 1102 and causing the gear rod 1103 to move leftward, and in conjunction with the transmission of the transmission gear set 12, the gear plate 13 drives the sector strip 91 to move rightward, thereby causing part of the sector strip 91 to move outward and move out of the through hole, thereby increasing the distance between part of the copper material and the second water tank 9, weakening the heat transmission effect, thereby reducing the heating effect on the cleaning agent in the second water tank 9, and finally causing the cleaning liquid in the second water tank 9 to heat up. The temperature in the third water tank 10 drops. As the temperature drops, the output end of the telescopic rod 1101 shrinks and returns to its original position (the toothed rod 1103 will be reset, and the toothed plate 13 will be driven to return to its original position through the transmission gear set 12). At this moment, the fan-shaped strip 91 returns to its original position. Subsequently, the temperature of the cleaning liquid inside the third water tank 10 begins to rise again, and the output end of the telescopic rod 1101 moves upward. The output end of the telescopic rod 1101 moves repeatedly in this way, maintaining the cleaning agent floating at 60°C±2°C, which is conducive to promoting the removal of the oil film by the cleaning agent.

[0029] It should be noted that, at this time, the transmission gear set 12 is a set of transmission gears meshingly connected with the toothed plate 13 and the gear rod 1103 .

[0030] As a preferred implementation in this embodiment, Figure 6 and Figure 7 As shown, the transmission gear set 12 includes a large one-way gear 1201 and a small one-way gear 1203 installed on the first rotating shaft, and a medium one-way gear 1202 and a small one-way gear 1203 installed on the second rotating shaft; The large one-way gear 1201 and the medium one-way gear 1202 are both meshed and connected with the toothed plate 13, and the two sets of small one-way gears 1203 are both meshed and connected with the gear rod 1103; The large one-way gear 1201 and the small one-way gear 1203 on the same rotating shaft drive the toothed plate 13 to move rightward only when rotating counterclockwise; The medium-sized one-way gear 1202 and the small one-way gear 1203 on the same rotating shaft drive the toothed plate 13 to move leftward only when rotating clockwise.

[0031] During operation, when the gear rod 1103 moves outward, the large one-way gear 1201 is driven to rotate through the small one-way gear 1203, thereby driving the tooth plate 13 to move outward (at this time, the other group of small one-way gears 1203 and the medium one-way gear 1202 do not affect the rotation of the large one-way gear 1201). When the gear rod 1103 retracts, the tooth plate 13 is driven to reset through the medium one-way gear 1202 (at this time, the other group of small one-way gears 1203 and the large one-way gear 1201 do not affect the rotation of the medium one-way gear 1201). 02 rotation), but because the size of the medium-sized one-way gear 1202 is smaller than that of the large one-way gear 1201, the extended length of the output end of the telescopic rod 1101 is consistent with the retracted length, causing the tooth plate 13 to drive the fan-shaped strip 91 to finally move outward. After the output end of the telescopic rod 1101 moves back and forth many times, it finally maintains a contracted state and remains unchanged. At this time, the temperature of the cleaning agent in the third water tank 10 is closer to 60℃±2℃, making the temperature control more accurate, which is more conducive to promoting the cleaning agent to remove the oil film on the copper material.

[0032] It should be noted that: 1. The smaller the size of the medium-sized one-way gear 1202 is than that of the large one-way gear 1201, the higher the accuracy of subsequent temperature adjustment will be, and the closer the final temperature will be to 60°C±2°C; 2. An L-shaped slide bar 16 is fixed on the T-shaped slide plate 92, and the end of the L-shaped slide bar 16 is slidably arranged in a slide groove arranged on the side end of the movable gear rod 24.

[0033] As a preferred implementation in this embodiment, an automatic resetting unit is further provided to control the tooth plate 13 to return to its original position after the copper material is stretched.

[0034] When the copper wire drawing is completed, the tooth plate 13 and the fan-shaped strip 91 are automatically reset.

[0035] As a preferred implementation in this embodiment, Figure 4-7 As shown, the automatic reset unit includes a movable gear rod 24 vertically slidably arranged at the right end of the T-shaped slide plate 92 and a reset spring 25 fixed to the left end of the second water tank 9 through a mounting rod 26; The right end of the return spring 25 is fixedly connected to the T-shaped slide plate 92; The lower end of the movable gear rod 24 is rotatably provided with an adjusting wheel 15, the upper end of the movable gear rod 24 is fixed with a weight-increasing block 23, and the movable gear rod 24 is meshedly connected with a driving gear 17 rotatably provided on the T-shaped slide plate 92; The left end of the tooth plate 13 is slidably penetrated by the column 27, and the right end of the tooth plate 13 is threadedly connected to the screw 18 through a threaded pipe. The screw 18 and the column 27 are both installed on the T-shaped slide plate 92. The mounting shaft of the driving gear 17 and the upper end of the screw 18 are both provided with a bevel gear 19, and the two sets of bevel gears 19 are meshed and connected.

[0036] At the beginning, when the copper material passes through the second water tank 9, the end of the copper material will form a conflict with the outer wall of the adjusting wheel 15, and finally the adjusting wheel 15 drives the movable gear rod 24 to move upward, and the movable gear rod 24 moving upward drives the driving gear 17 to rotate, and drives the screw 18 to rotate through the cooperation of the two sets of bevel gears 19, and finally the toothed plate 13 moves upward and completes the meshing connection with the large one-way gear 1201 and the medium one-way gear 1202; When the copper material is stretched, since there is no copper material to support the bottom of the adjusting wheel 15, it moves downward under the action of the gravity of the weight 104, the movable gear rod 24 and the adjusting wheel 15, and drives the driving gear 17 to rotate in the reverse direction, and finally causes the tooth plate 13 to move downward, releasing its meshing connection with the large one-way gear 1201 and the medium one-way gear 1202, and finally under the action of the elastic force of the reset spring 25, the tooth plate 13 drives the fan-shaped strip 91 to return to its original position.

[0037] It should be noted that each time the copper material is changed for wire drawing annealing, the temperature self-regulating unit needs to readjust the temperature.

[0038] As a preferred implementation in this embodiment, Fig. 9 As shown, a stirring wheel 21 made of rubber material is rotatably provided at the bottom of the inner cavity and the bottom of the third water tank 10 , and a stirring blade 22 is provided at the end of the mounting shaft of the stirring wheel 21 .

[0039] When the copper material moves, the stirring wheel 21 is squeezed with the copper material, and through friction, the stirring blade 22 is caused to rotate and stir in the third water tank 10, which is beneficial to the mixing of new and old cleaning agents and the removal of the oil film.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
