Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of red copper strip production, and particularly relates to a high-precision alloy copper strip processing hot pressing device capable of preventing edge cracking. BACKGROUND

[0002] Copper strip is a general term for copper plate and copper strip. Copper plate is a plate formed by rolling of copper material, and copper strip refers to a copper rolling product with a thickness of 0.06-1.5 mm. Copper strip can be divided into brass strip, red copper strip and bronze strip. During copper strip processing, a hot pressing device is used to hot press the copper strip, so as to obtain good mechanical properties, physical properties and corrosion resistance.

[0003] To this end, a hot pressing device for aluminum alloy plate processing is provided in Chinese Patent No. CN202110115586.6. The device realizes intermittent hot pressing of the plate, and the driving assembly drives the toothed structure to move, so that the sliding plate intermittently slides on the fixed shaft, thereby changing the hot pressing position of the plate and realizing effective moving hot pressing of the device. However, the hot pressing device in the above-mentioned patent has the following problems:

[0004] (1) The hot pressing device in the above-mentioned patent has poor hot pressing effect and does not have the function of preventing edge cracking during hot pressing of the copper strip. This can cause the copper strip to crack on the edge side after hot pressing, which not only affects the hot pressing effect of the copper strip, but also reduces the quality of the copper strip and affects its use;

[0005] (2) The hot pressing device in the above-mentioned patent does not have a unwinding function. Since the copper strip roll is heavy as a whole, it is inconvenient for personnel to move and load. The lack of unwinding function makes it inconvenient to unload the copper strip, affecting the hot pressing processing of the copper strip;

[0006] (3) The hot pressing device in the above-mentioned patent is not convenient to wind. Since the weight of the copper strip increases continuously during winding, it is easy to cause instability during the winding process of the copper strip. In addition, the copper strip needs to be processed after hot pressing, and it is inconvenient for personnel to unload.

[0007] Therefore, a high-precision alloy copper strip processing hot pressing device capable of preventing edge cracking is proposed to solve the problems mentioned above. SUMMARY

[0036] The working principle of this embodiment is as follows: Unwinding is required during the hot pressing of the copper strip, such as... Figure 1 , Figure 2 and Figure 5 As shown, the operator rolls the copper strip roll through the inclined block 22 onto the slide bar 28 on the unwinding frame 3. Then, the operator rotates the two drive turntables 32, which drive the drive screw 31 connected to the support rod 30 to rotate. This allows the drive screw 31 to rotate within the connecting bearing connected to the support plate 29, which in turn drives the support plate 29 to slide on the slide bar 28 connected to the lifting plate 25. This allows the two support columns to be inserted into the copper strip roll. Then, the third electric hydraulic cylinder 27 is opened. The two third electric hydraulic cylinders 27 drive the lifting block 26 connected to the lifting plate 25, which in turn drives the lifting plate 25 to rise along the guide rod 24. This allows the copper strip roll to be lifted onto the body via the support columns, facilitating unwinding during hot pressing.

[0037] When hot pressing copper strip, such as Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the copper strip is unwound and passes between two guide rollers 21. The adjusting slider 18 connected to the guide plate 17 is connected to the adjusting screw 19 through a fixed bearing. When the operator rotates the adjusting turntable 20, the adjusting screw 19 can be driven to adjust the distance between the two guide rollers 21, ensuring the guidance of the copper strip. The copper strip is placed on the hot press plate 12, passes through the work frame 1, and then is wound around the take-up wheel 38. The copper strip passes through the fixed frame 39 and is fixed by the fixing bolts. The take-up frame 6 is connected to the pusher 33 and the second moving wheel 35 to facilitate the transfer of the copper strip. The take-up column 36 connected to the take-up motor 34 is inserted into the cross slot of the take-up wheel 38. The clamp 37 connected to the take-up column 36 ensures the limit of the take-up wheel 38 and facilitates disassembly by the operator.

[0038] When hot pressing copper strip, such as Figure 1 Figure 2 Figure 5 Figure 1 Figure 2 Figure 6 Figure 7 Figures 1-7As shown, turning on the winding motor 34 drives the winding column 36, which in turn rotates the winding wheel 38, thus pulling the copper strip to move and wind it up. At this time, turning on the electric heating tube connected to the hot press plate 12 heats the hot press plate 12. Simultaneously, turning on the electric heating roller 16 causes the first electric hydraulic cylinder 5 to drive the two side pressure bars 7, which in turn drives the side pressure rollers 11 fixed to the side pressure bars 7 by the mounting plate 10. This ensures that the copper strip is pressed tightly on the sides and that the copper strip can move. Turning on the second electric hydraulic cylinder 9 on the hot press frame 8 drives the lifting frame 13, which allows the guide block 14 to move. Sliding on the guide slide 15, the drive motor drives the drive roller and drives multiple electric heating rollers 16 to rotate through the drive gear. Under the action of the second electric hydraulic cylinder 9, the electric heating rollers 16 can press against the surface of the copper strip. The electric heating rollers 16 cooperate with the hot press plate 12 to ensure hot pressing of the copper strip, ensure better hot pressing effect, and avoid cracking of the copper strip edges, thus ensuring the quality of the copper strip. At this time, the winding column 36 drives the winding wheel 38 to wind the copper strip. The stabilizing wheel 41 in the stabilizing groove of the stabilizing plate 40 contacts and rotates with the winding wheel 38 to ensure support for the winding wheel 38 and ensure stable winding.
