[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4, including: a clamping part 5; two sets of clamping parts 5 are arranged in a mirror image. A support block 8 is fixedly installed at the lower end of the clamping part 5, and a slider 9 is fixedly installed at the lower end of the support block 8. A sliding guide plate 10 is arranged below the slider 9. Chutes are opened on both sides of the sliding guide plate 10, so that both sides of the slider 9 are slidably installed at the chutes of the sliding guide plate 10. A hole is opened at the center of the slider 9. The slider 9 will drive the clamping part 5 to slide on the sliding guide plate 10 through the support block 8, so that the clamping part 5 clamps the aluminum substrate.

[0026] At the centers of both ends of the sliding guide plate 10, there is a left - right hand threaded screw rod 12. One end of the left - right hand threaded screw rod 12 is fixedly installed with a connecting rod 14. A second bearing 19 is arranged at the connection between the left - right hand threaded screw rod 12 and the connecting rod 14. The inner ring of the second bearing 19 is nested on the surface of the connecting rod 14, and the outer ring of the second bearing 19 is adapted to the opening opened on the surface of the base 13, so that the second bearing 19 is fixedly installed at the opening on the surface of the base 13. This enables the connecting rod 14 to rotate through the second bearing 19 when passing through the surface of the base 13 to reduce friction, making the rotation of the connecting rod 14 smoother. A blocking block 18 is arranged at one end of the second bearing 19 close to the connecting rod 14. A long - strip - shaped opening is opened on one side of the blocking block 18. A hole adapted to the connecting rod 14 is opened at the center of the long - strip - shaped opening, and the long - strip - shaped opening is smaller than the hole. The connecting rod 14 passes through the hole in the blocking block 18, enabling the connecting rod 14 to rotate in the hole of the blocking block 18. The two sides of the long - strip - shaped opening of the blocking block 18 are divided into two parts. A bolt 17 is arranged on the surface of the blocking block 18. The bolt 17 passes through the long - strip - shaped opening opened on the blocking block 18 and is threadedly connected to the two parts on both sides of the long - strip - shaped opening of the blocking block 18. By rotating the bolt 17, the blocking block 18 deforms and tightens towards the connecting rod 14, making the connecting rod 14 unable to rotate.

[0027] The outer wall of the sliding guide plate 10 is fixedly installed with a base 13. An opening is opened on the surface of the base 13, so that a first bearing 15 is fixedly installed at the opening on one side of the base 13, and the inner ring of the first bearing 15 is also nested on the surface of the connecting rod 14. The second bearing 19 and the first bearing 15 are located on both sides of the base 13 respectively. Among them, the connecting rod 14, the blocking block 18, and the bolt 17 sandwiched between the second bearing 19 and the first bearing 15 are all located inside the base 13. A hand - cranking part 16 is fixedly installed at one end of the connecting rod 14 close to the first bearing 15. By rotating the hand - cranking part 16, the connecting rod 14 drives the left - right hand threaded screw rod 12 to rotate at the centers of both ends of the sliding guide plate 10, and the slider 9 slides oppositely along the chutes on both sides of the sliding guide plate 10 and the threaded surface of the left - right hand threaded screw rod 12. The clamping part 5 will clamp on the surface of the aluminum substrate. A limiting part 11 is arranged in the middle of the sliding guide plate 10, and the convex parts at both ends of the limiting part 11 are fixedly installed at the tops of both sides of the sliding guide plate 10.

[0028] Two sets of holes are provided at the upper end of the clamping part 5. A spring group 6 is fixedly arranged in the holes. A support rod is arranged at the center of the spring group 6. A part of the support rod extends into the holes of the clamping part 5. When the support plate 7 is pressed down by the cross plate 3, the spring group 6 will not tip over. The spring group 6 will retract into the holes along the support rod. A support plate 7 is arranged at the upper end of the spring group 6. The copper plate is placed on the surface of the support plate 7. When the cross plate 3 presses down the support plate 7, the copper plate will be pressed down by the cross plate 3 following the support plate 7 and then be squeezed and cut by the pressing block 4. The redundant copper plate will be lifted upward by the elasticity of the spring group 6 at the lower end of the support plate 7, which makes the steps of replacing the copper plate more convenient.

[0029] An operating table 1 is arranged on the lower end surface of the clamping part 5. A long strip-shaped sliding groove is provided on the surface of the operating table 1, so that the support block 8 at the lower end of the clamping part 5 slides radially at the long strip-shaped sliding groove of the operating table 1. A hydraulic press 2 is arranged at the upper end of the operating table 1. The output end of the hydraulic press 2 is fixedly installed with a cross plate 3. Since the hardness of the copper plate is insufficient and it cannot press the support plate 7, when the cross plate 3 presses down, it will press the support plate 7 and the copper plate placed on its surface so that it will not be bent by the inclined surfaces of the clamping part 5 and the pressing block 4. A pressing block 4 is arranged at the lower end of the cross plate 3. A rectangular convex block is arranged at the lower end of the pressing block 4. And an electric heating element is arranged inside the pressing block 4. The electric heating element can heat the rectangular convex block of the pressing block 4. By the way of pressing down the cross plate 3 and the pressing block 4, the rectangular convex block at the lower end of the pressing block 4 and the inclined surfaces of the clamping part 5 and the pressing block 4 will heat and squeeze and cut the copper plate pressed onto the surface of the aluminum substrate, so that the copper plate covers the surface of the aluminum substrate.

[0030] Working principle: Place the aluminum substrate on the surface of the operating table 1. Shake the hand-operating part 16 on the surface of the base 13 to rotate the left-right hand thread lead screw 12. The slider 9 moves the clamping part 5 towards each other with the rotation of the left-right hand thread lead screw 12 and clamps the aluminum substrate. Then tighten the bolt 17 to fix the left-right hand thread lead screw 12. Place the copper plate on the surface of the support plate 7. Then start the hydraulic press 2 to make the output end of the hydraulic press 2 drive the cross plate 3 and the pressing block 4 to press down. First, the pressing block 4 will first contact the copper plate and press it down. Immediately afterwards, the cross plate 3 will press down the support plate 7. When the pressing block 4 presses down to the aluminum substrate, the convex block on the surface of the pressing block 4 will cooperate with the inclined surfaces of the pressing block 4 and the clamping part 5 to squeeze and cut the copper plate. When the cross plate 3 and the pressing block 4 rise, the copper plate is lifted by the support plate 7. Take the remaining copper plate on the surface of the support plate 7 and replace it to carry out the next pressing work.
