Description

Technical Field

[0001] The invention relates to the technical field of metal processing, in particular to an automatic shaping copper row extruder. Background Art

[0002] Copper busbar extruder is a kind of equipment used to produce copper busbars. It is mainly used to process copper rods into copper busbars with specific cross-sectional shapes and sizes through extrusion process. Copper busbars are widely used in cable connection and heat dissipation in industries such as electricity, electronics, communications, and automobiles.

[0003] However, the existing copper row extrusion has the following defects:

[0004] First, in the existing copper bar extrusion, when the copper bar is passed through the machine to complete the surface processing of the copper bar, the size and width of the copper bar itself will be different. In addition, the required width of the surface extrusion in different working environments is also different. The extruder can only adapt to one size of copper bar. For copper bars of different sizes, the extruder needs to be replaced or cumbersome adjustments need to be made, which will increase the downtime in the production process and reduce the overall production efficiency. Replacing the extruder will directly lead to an increase in metal processing costs and a lot of material consumption. On the other hand, the copper bars with different requirements still use one extrusion width size, which will result in the copper bar finished product being too single, resulting in the copper bar's performance being limited and unable to adapt to diversity.

[0005] Secondly, after the copper busbar has completed the extrusion process, although the surface has been coated with thermoplastic, it cannot be ensured that the thermoplastic has been evenly applied. At the same time, there may be bubbles that have not been discharged under the covered thermoplastic. The uneven thermoplastic layer may cause the electrical conductivity, thermal conductivity and other properties of the copper busbar to be inconsistent, affecting the overall performance of the product. In addition, the uneven thermoplastic layer will form stress concentration points in certain parts, reducing the mechanical strength and durability of the product. At the same time, the internal bubbles will block the heat conduction path, reduce the thermal conductivity of the copper busbar, and affect its effect in heat dissipation applications.

[0006] Finally, copper busbars need to go through many processes before production and processing, so that some foreign particles will be attached to their surface before they are sent to complete the plastic molding. If the hardness of the foreign particles is high, they will cause wear and tear on the mold during the extrusion process and accelerate the aging of the mold. In addition, the foreign particles will also cause unevenness, pitting, scratches and other appearance defects on the surface of the copper busbar. Summary of the invention

[0051] In other aspects, this embodiment also provides a regulation structure, such as Figure 1 - Fig. 9 As shown, the adjustment mechanism 300 includes a bending plate 305 adapted to the extrusion of copper bars of different sizes. The bending plate 305 is arranged on the right side of the main turntable 101.

[0052] As a preferred implementation in this embodiment, Figure 1 - Fig. 9 As shown, the adjustment mechanism 300 includes a roller 301, which is slidably connected to the upper surface of the support platform 103.

The top of the boss 302 is fixedly connected to a boss 2 303, and the boss 2 303 is trapezoidal.

[0053] In this embodiment, Figure 1 - Fig. 9 As shown, the front and rear sides of the boss 2 303 are in contact with the roller 2 304, the two rollers 304 and the four bending plates 305 are rotatably connected, the four bending plates 305 are divided into two groups and are symmetrically located on the front and rear sides of the copper busbar 102, and a telescopic plate 306 is arranged inside the bending plate 305, the middle bending point of the bending plate 305 is slidably connected to the support platform 103, and the telescopic plate 306 is rectangular in shape and has four vertices.

[0055] Compared with the existing technology, the device can adapt to copper bars of different sizes, allowing more types of copper bars to be processed, avoiding frequent replacement of extruders, effectively reducing downtime in the production process, improving overall processing efficiency, and avoiding increased costs due to machine replacement. On the other hand, the extrusion on the surface of the copper bar can be changed to different thicknesses as needed, making the extrusion on the back of the copper bar more diverse and the performance more comprehensive.

[0056] In this embodiment, Figure 1 - Fig. 9 As shown, a flattening structure is proposed. The flattening mechanism 400 includes a spring 405 that fully adapts to the shape change of the copper busbar during rolling. The spring 405 is arranged on the right side of the bending plate 305. The flattening mechanism 400 is used to flatten and smooth the outside of the completed thermoplastic copper busbar and squeeze out the internal bubbles.

[0057] In this embodiment, Figure 1 - Fig. 9 As shown, the flattening mechanism 400 includes a gear ring 401, the diameter of the gear ring 401 is adapted to the diameter of the outer ring 104 and is fixedly connected to the right side of the outer ring 104, the top of the gear ring 401 is meshedly connected with a gear ring 2 402, the gear ring 2 402 is in a horizontal state, the side of the gear ring 402 away from the gear ring 1 401 is meshedly connected with a gear ring 2 403, and the side of the gear ring 2 403 away from the gear ring 1 401 is fixedly connected with a turntable 2 404.

[0059] Compared with the existing technology, the device can evenly roll the thermoplastic on the surface of the extruded copper busbar, and squeeze out the bubbles between the copper busbar and the thermoplastic, avoiding the reduction of electrical conductivity and thermal conductivity caused by uneven surface thermoplastic. It can also avoid the stress concentration points in the thermoplastic layer, improve product durability, and prevent internal bubbles from blocking the heat conduction path, effectively improving thermal conductivity.

[0060] The following is the specific working principle of the above embodiment:

[0061] Before the copper bar enters the machine for extrusion, it is necessary to first clean all the impurities adhering to its surface during the previous various processing steps, and then the extrusion operation can be performed. An outer ring 104 is fixedly connected above the support table 103, and the inner part of the outer ring 104 is rotatably connected to the main turntable 101, and the copper bar plate 102 passes through the main turntable 101 from left to right, and is fixedly connected to the spiral disk 201 on the left side of the main turntable 101. The lower left side of the spiral disk 201 is meshed with a worm 202, and the worm 202 is at a side away from the main turntable 101. The end is fixedly connected to the shaping table 105, and the operator manually starts the motor 106, and the motor 106 drives the worm 202 to rotate, and the worm 202 drives the spiral disk 201 to rotate. At the same time, the transmission roller 203 fixedly connected to the front end of the worm 202 also rotates at the same speed. During the rotation, since the copper bar plate 102 is placed above the transmission roller 203, the transmission roller 203 supports the copper bar plate 102 above when it rotates, and uses its own rotation force to push the copper bar plate 102 from left to right, so that it can continuously and continuously complete the extrusion. Gear 1 204 is meshed and connected to the end of the worm 202 away from the main turntable 101. The upper part of the gear 1 204 is rotatably connected to the elliptical block 205, and the outer side of the elliptical block 205 is slidably connected to the square frame 206. The rotation of the gear 1 204 and the elliptical block 205 can allow the square frame 206 to reciprocate in a direction perpendicular to the movement of the copper bar plate 102, such as Fig.10 While moving, the top of the square frame 206 is fixedly connected to the connecting shaft 207, and the connecting shaft 207 is divided into two parts, one part is located above the copper bar plate 102, and the other part is located below the copper bar plate 102. The sponge 208 is fixedly connected to the end of the connecting shaft 207 away from the square frame 206, and the copper bar plate 102 passes between the upper and lower connecting shafts 207 and the sponge 208. Driven by the square frame 206, the connecting shaft 207 and the sponge 208 scrape the copper bar plate 102 passing through the middle of the sponge 208 back and forth to clean the particle impurities on the surface of the copper bar plate 102.

[0062] After the copper bar plate 102 is surface treated, the extrusion process can be started. The copper bar plate 102 continues to move toward the shaping table 105 under the support and drive of the driving roller 203, passes through the middle of the main turntable 101 and the outer ring 104, and finally reaches the adjustment mechanism 300. Since the sizes of copper bars under different requirements are different, some copper bars are wider, while some copper bars are narrower, it is impossible to use only a single thermoplastic extrusion tool to operate the copper bar, otherwise it is bound to cause some places on the surface of the copper bar to be unable to adhere to thermoplastic, and even some larger copper bars cannot pass through them, so it is necessary to be able to adapt to multiple types of copper bars. A roller 301 is also slidably connected above the copper bar plate 102. The operator manually pulls the roller 301 to move the roller 301 toward or away from the copper bar plate 102. A boss 302 is provided at one end of the roller 301 facing the copper bar plate 102. The roller 301 and the bottom surface of the boss 302 are in conflict with each other. Since the bottom surface of the boss 302 is in an inclined state and its height gradually decreases from the near side of the roller 301 to the far side, when the roller 301 is pulled away from the boss 302, the higher point of the slope of the boss 302 contacts the roller 301, forcing the boss 302 connected to the top boss 303 to descend together, and when the roller 301 is pushed toward the direction of the boss 302, the lower point of the slope of the boss 302 contacts the roller 301, forcing the boss 302 and the boss 303 to rise.

[0063] When the copper busbar 102 passed through is large in size, the upper bending plate 305 and telescopic plate 306 need to be wider. At this time, the roller 1 301 is manually pulled away from the boss 1 302. At this time, the boss 1 302 and the boss 2 303 fixedly connected at the top are lowered together. Since the boss 2 303 is trapezoidal in shape, the bottom end is wide and the top end is narrow. The roller 2 304 abuts against the side surface of the boss 2 303, and the distance between the two rollers 2 304 gradually decreases from the bottom to the top. When the position of the boss 2 303 is lowered, the front and rear side slopes of the boss 2 303 are also lowered, causing the two rollers 2 304 abutting against the slope to gradually move toward each other, and the distance between them becomes smaller. This causes the bottom ends of the bending plates 305 connected to the rollers 2 304 to also move toward each other. Therefore, the lower half of the bending plates 305 will deflect in the process of approaching each other, and the bottom distance will become smaller. This deflection makes the bottom distance of the bending plates 305 smaller, but it will be reflected at the top of the bending plates 305 as an increase in the top distance. Since the top of the bending plate 305 is rotationally connected to the top of the telescopic plate 306, when the spacing between the tops of the bending plates 305 increases, the bending plates 305 will move away from each other, that is, they will shift in the direction away from the copper busbar 102, and this shift will drive the rotatably connected telescopic plate 306 to change its own size. When the tops of the bending plates 305 move away from each other, the top of the telescopic plate 306 is also stretched, and at the same time, the bottom of the telescopic plate 306 will also be stretched synchronously, and the stretching distance depends on the length of the top of the bending plate 305 moving away from each other.At this time, the length of the telescopic plate 306 is stretched, and the space that the telescopic plate 306 can accommodate is larger, so it can adapt to the passage of a copper bar of a larger size. When the copper bar plate 102 passes through it, the extrusion box 307 is slidably connected inside the telescopic plate 306. Initially, the size of the extrusion box 307 is set to be consistent with the length of the telescopic plate 306 when it is stretched to the longest. Only in this way can the extrusion box 307 always accommodate the telescopic plate 306 with constantly changing sizes inside. Therefore, the length of the telescopic plate 306 cannot exceed the extrusion box 307. Since the bottom surfaces of the telescopic plate 306 and the extrusion box 307 are provided with small holes, the thermoplastic that needs to be coated on the surface of the copper bar plate 102 is installed inside the extrusion box 307. When the copper bar plate 102 passes from below, the thermoplastic The thermoplastic flows out from the small holes under the extrusion box 307 and the telescopic plate 306. During this process, the boss 2 303 is located under the telescopic plate 306 and the extrusion box 307, and does not block the outflow of the thermoplastic in the extrusion box 307. Moreover, there is no other interfering object blocking between the telescopic plate 306 and the extrusion box 307. Therefore, after the thermoplastic flows out of the extrusion box 307, it will pass through the surface of the telescopic plate 306 and be coated on the surface of the copper bar plate 102. Since the telescopic plate 306 is annular and is located on the surface of the copper bar plate 102 in a whole circle and completely surrounds the copper bar plate 102, the thermoplastic can be coated on the surface of the entire copper bar plate 102 without dripping onto the support platform 103 below, thereby avoiding waste of thermoplastic. When the length of the copper busbar 102 to be passed is small, the roller 1 301 can be pushed toward the boss 1 302 and the direction, so that the boss 1 302 and the boss 2 303 are both raised, and the side distance of the boss 2 303 that the roller 2 304 contacts is continuously increased. At this time, the two rollers 2 304 will move away from each other, which will be reflected on the bottom ends of the bending plates 305. The mutual distance of the bottom ends of the bending plates 305 will make the top ends of the bending plates 305 approach each other, that is, the telescopic plate 306 connected to the top ends of the bending plates 305 will also be reduced in size, and at this time, a smaller copper busbar 102 can be accommodated to pass through it.

[0064] When the thermoplastic flows out of the extrusion box 307, the final shaping of the thermoplastic is to completely fit the bottom surface of the copper busbar 102, and completely fit the top surface of the telescopic plate 306, that is, the annular space formed between the telescopic plate 306 and the copper busbar 102 will eventually be coated with thermoplastic, which requires that the size of the telescopic plate 306 should be changed at any time according to the size of the copper busbar 102, because if the telescopic plate 306 maintains a sufficiently large size and the copper busbar 102 can be large or small, the thermoplastic layer between the telescopic plate 306 and the copper busbar 102 will also be uneven, but this is not conducive to the copper busbar 102. The correct situation is that no matter how big or small the copper busbar 102 is, the thickness of the thermoplastic on the surface of the copper busbar 102 is consistent, which can ensure that the copper busbar 102 can more smoothly realize its function. If the telescopic plate 306 does not move, the surface thermoplastic will be too thick when the size of the copper busbar 102 is small, and too thin when the size of the copper busbar 102 is large. This is not conducive to the subsequent processing and use of the copper busbar 102, including bending and shaping. The correct method is to make the telescopic plate 306 correspond to the size of the copper busbar 102 in real time. If the copper busbar 102 is larger, the telescopic plate 306 is also larger; if the copper busbar 102 is smaller, the telescopic plate 306 is also smaller. In this way, the surface thermoplastic thickness is ensured to be the same, and the subsequent work of the copper busbar 102 is better achieved.

[0065] After the copper busbar 102 is coated with thermoplastic, some bubbles may remain between the surface of the copper busbar 102 and the thermoplastic. These bubbles must be removed and the thermoplastic on the surface of the copper busbar 102 must be more uniform. A gear ring 1 401 is fixedly connected to the right side of the main turntable 101. When the motor 106 drives the worm 202 to engage with the spiral disk 201 and rotate, the spiral disk 201 will drive the main turntable 101 to rotate, and the rotation of the main turntable 101 will rotate together with the gear ring 1 401. The top of the gear ring 1 401 is engaged with the gear 2 402, and the gear 2 402 engages with the gear ring 2 403 and rotates synchronously. The gear ring 2 403 is fixedly connected to the turntable 2 404 on the side away from the main turntable 101, and the upper and lower ends of the inner side of the turntable 2 404 are symmetrically fixedly connected with the spring 405, and the side of the spring 405 away from the turntable 2 404 is fixedly connected to the grinding wheel 406. When the gear ring 2 403 drives the turntable 2 404 and the grinding wheel 4 06 rotates, the copper bar plate 102 also passes through the inside of the turntable 404 synchronously. At this time, the turntable 404 drives the inner wall of the rolling wheel 406 to rotate around the copper bar plate 102 and roll the thermoplastic on the surface of the copper bar plate 102. The cross section of the copper bar plate 102 is rectangular, and under the action of the outer spring 405, it can be ensured that every part can be covered and rolled in place. When encountering the turning point of the copper bar plate 102, the spring 405 will shrink under pressure, and at the same time drive the rolling wheel 406 to adapt to the shape of the copper bar plate 102. In the process of continuous rotation, the rolling wheel 406 completes the extrusion and flattening of the surface of the copper bar plate 102, discharges the remaining bubbles inside, and rolls the thermoplastic on the surface of the copper bar plate 102 evenly.
