The lower ends of the two L-shaped clamping rods 12 are close to the support platform 20 and are provided with an inclined surface. When the support platform 20 is pushed toward the support box 11, the two U-shaped blocks 23 slide on the inclined surfaces of the lower ends of the two L-shaped clamping rods 12, pushing the two L-shaped clamping rods 12 to rise vertically and squeeze the two first springs 13 respectively. When the lower ends of the two L-shaped clamping rods 12 coincide with the gaps in the two U-shaped blocks 23, under the elastic force of the two first springs 13, the lower ends of the two L-shaped clamping rods 12 are respectively slid and engaged in the two U-shaped blocks 23, fixing the position of the support platform 20.

[0024] In one embodiment of the present invention, Figure 1 、 Figure 2 and Figure 4As shown, two limit rods 111 are fixedly connected to the upper end of the inner wall of the support box 11, and the two limit rods 111 respectively pass through the two L-shaped clamping rods 12 and are slidably connected to the two L-shaped clamping rods 12 respectively. The two first springs 13 are slidably sleeved on the outer surfaces of the two limit rods 111 respectively, and a circular slide rod 21 is fixedly connected to one side of the inner wall of the support box 11, and the second spring 22 is slidably sleeved on the outer surface of the circular slide rod 21. The support platform 20 is provided with a connecting hole 202 between the two U-shaped blocks 23, and the second spring 22 is arranged to pass through the connecting hole 202.

[0025] Specifically, after driving the breaking tool 16 to rise, the support plate 14 above the breaking tool 16 slides up in the support box 11, pushing the two L-shaped clamping rods 12 to slide up respectively, and sliding and squeezing the two first springs 13 on the surface of the two limit rods 111, so that the lower ends of the two L-shaped clamping rods 12 are respectively separated from the two U-shaped blocks 23 on one side of the support platform 20, releasing the lock of the support platform 20, and under the elastic force of the second spring 22, the support platform 20 is pushed to slide on the base 10, so that the support platform 20 is separated from the support box 11, so that the operator does not need to find the position of the steel sheet in the complex mold structure or directly below the breaking tool 16, and can directly pick up the steel sheet on the pop-up support platform 20, which greatly saves the time of taking and placing the steel sheet. At the same time, the operator does not need to grope for the steel sheet directly below the breaking tool 16, avoiding the risk of injury due to accidentally touching the breaking tool 16 that still has residual heat or sharp edges.

[0026] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, two T-shaped slide bars 101 are fixedly installed on both sides of the second spring 22 at the upper end of the base 10, and T-shaped slots 201 are opened on both sides of the bottom of the support platform 20. The T-shaped slide bars 101 are slidably connected with the T-shaped slots 201. Through the limiting cooperation between the T-shaped slide bars 101 and the T-shaped slots 201, the support platform 20 always fits the surface of the base 10 when sliding.

[0027] In one embodiment of the present invention, Figure 4 As shown, the fixing mechanism includes a bidirectional screw rod 24 rotatably installed in the support platform 20, the threads at both ends of the bidirectional screw rod 24 are set in opposite directions and two symmetrically arranged splints 25 are respectively provided at both ends, the two ends of the bidirectional screw rod 24 respectively pass through the two splints 25 and are threadedly connected to the two splints 25, and a fixing plate 203 is fixedly installed on the upper end of the support platform 20, and two symmetrically arranged second sliding holes 204 are provided on the fixing plate 203, and the two second sliding holes 204 are communicated with the interior of the support platform 20, and the two splints 25 respectively pass through the two second sliding holes 204 and are slidably connected to the two second sliding holes 204. The steel sheet on the fixing plate 203 can be fixed by the two splints 25, thereby facilitating the fixation of steel sheets of different sizes.

[0028] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, a circular shaft 27 is rotatably installed on one side of the inner wall of the support platform 20 away from the two U-shaped blocks 23, and a bevel gear 26 is fixedly installed between the end of the circular shaft 27 away from the inner wall of the support platform 20 and the middle position of the bidirectional screw rod 24. The two bevel gears 26 are engaged with each other, and a second motor 28 is fixedly installed on the side wall of the support platform 20. The output end of the second motor 28 passes through the support platform 20 and is fixedly connected to the circular shaft 27.

[0029] In detail, when fixing the steel sheet on the fixed plate 203, the steel sheet is placed on the fixed plate 203, and the second motor 28 is started so that the output end of the second motor 28 drives the circular shaft 27 to rotate, and the two bevel gears 26 cooperate to drive the bidirectional screw rod 24 to rotate, and then the two clamping plates 25 slide close to each other in the two second sliding holes 204, clamping and fixing the steel sheet on the fixed plate 203 to avoid displacement when breaking.

[0030] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, a protective shell 112 is fixedly installed on the upper end of the support box 11, and a long tooth rod 17 is fixedly connected to the upper end of the support plate 14. The upper end of the long tooth rod 17 passes through the support box 11 and is slidably installed in the protective shell 112. A circular gear 18 is rotatably installed between the inner walls of the protective shell 112, and the circular gear 18 is engaged with the long tooth rod 17. A first motor 19 is fixedly installed on the outer surface of the protective shell 112. The output end of the first motor 19 passes through the protective shell 112 and is fixedly connected to the center end of the circular gear 18. The circular gear 18 is driven to rotate by the first motor 19, further pushing the long tooth rod 17 to descend, thereby pushing the breaking tool 16 at the lower end of the support plate 14 to vertically descend, and performing a breaking operation on the steel sheet on the fixed plate 203.

[0031] Furthermore, the first motor 19 drives the circular gear 18 to rotate, causing the long tooth rod 17 to rise vertically in the support box 11 and the protective shell 112, and then pulls the support plate 14 to slide and rise in the support box 11, thereby driving the two L-shaped clamping rods 12 to rise and squeeze the two first springs 13 respectively. When the lower ends of the two L-shaped clamping rods 12 break away from the two U-shaped blocks 23 and the support platform 20 pops out from the support box 11, the first motor 19 is turned off. Under the elastic force of the two first springs 13, the support plate 14 can be squeezed down to reset the two L-shaped clamping rods 12.

[0032] In one embodiment of the present invention, Figure 2 and Figure 3As shown, an elongated slot 141 is provided at the lower end of the support plate 14 near the opening of the support box 11, and a accommodating box 15 is slidably installed in the elongated slot 141. The breaking tool 16 is slidably installed in the accommodating box 15, and a laser 151 is fixedly installed at the lower end of the accommodating box 15 on the side close to the breaking tool 16. Bolts 152 are inserted at both ends of the side of the accommodating box 15 away from the breaking tool 16, and the two bolts 152 respectively penetrate the accommodating box 15 and are threadedly connected to the accommodating box 15. The two bolts 152 are arranged close to the outer surface of the breaking tool 16 at one end near the breaking tool 16. By providing two bolts 152, it is convenient to disassemble and assemble the breaking tool 16 in the accommodating box 15.

[0033] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, a fixed block 144 is fixedly installed on one side of the upper end of the support plate 14, and a first sliding hole 142 is opened in the elongated groove 141. The first sliding hole 142 is communicated with the upper end of the support plate 14 and is located between the fixed block 144 and the long tooth rod 17. A threaded rod 143 is rotatably installed between the fixed block 144 and the long tooth rod 17. A moving block 153 is fixedly connected to the accommodating box 15. The moving block 153 passes through the first sliding hole 142 and is slidably connected to the first sliding hole 142. The threaded rod 143 passes through the moving block 153 and is threadedly connected to the moving block 153. One end of the threaded rod 143 passes through the fixed block 144 and is fixedly connected to the knob 145.

[0034] Specifically, when the position of the breaking tool 16 needs to be adjusted, the threaded rod 143 is driven to rotate by turning the knob 145, so that the moving block 153 slides in the first sliding hole 142, thereby driving the accommodating box 15 to slide in the elongated groove 141, and then the laser 151 on the accommodating box 15 will be aligned with the position on the steel sheet that needs to be broken, thereby facilitating the adjustment of the breaking position on the steel sheet.

[0035] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
