A first cutting cylinder 5 is installed on the other end of the connecting frame 4 near the panel 9. A cutting assembly 2 is connected to the end of the first cutting cylinder 5, and the cutting assembly 2 can be parallel to the panel 9 by the rotation of the connecting frame 4. A parallel clamping mechanism 8 is disposed on one side of the panel 9 close to the bottom plate 3 , and the parallel clamping mechanism 8 can adhere the metal sheet to the panel 9 .

[0020] This embodiment is implemented as follows: when in use, first feed the metal sheet to be cut into the support table 1, connect the metal sheet to the parallel clamping mechanism 8, and use the parallel clamping mechanism 8 to stick the metal sheet to the panel 9; then, by rotating the connecting frame 4, set the cutting assembly 2 parallel to the metal sheet, and control the cutting assembly 2 to stick and fix the metal sheet through the first cutting cylinder 5, the cutting assembly 2 presses and fixes the two sides of the cutting position, and the metal sheet is cut by the cutting assembly 2. At the same time, the smaller metal sheet part cut out falls with the recovery of the cutting assembly 2 to achieve unloading; then, the remaining metal sheet is fed again to the bottom of the cutting assembly 2, and this reciprocating process is achieved.

[0021] See also Figures 1 to 6 As a preferred embodiment of the present application, the cutting assembly 2 includes a mounting plate 201, a cutting tool 205 longitudinally mounted on the central axis of the mounting plate 201, a pressing mechanism 202 and a fixing plate 203, wherein the fixing plate 203 and the pressing mechanism 202 are symmetrically arranged on both sides of the cutting tool 205, a plurality of second cutting cylinders 204 are arranged at one end of the cutting tool 205 close to the mounting plate 201, and the plurality of second cutting cylinders 204 are arranged on the mounting plate 201, and a screw groove 214 is also horizontally opened on the mounting plate 201, and an adjusting screw 207 is arranged in the screw groove 214 One end of the adjusting screw 207 extends to the outside of the screw groove 214, and a driving motor 208 is also provided on the side of the mounting plate 201. The power output shaft of the driving motor 208 is connected to the end of the adjusting screw 207 extending to the outside of the screw groove 214.

The pressing mechanism 202 and the side of the fixing plate 203 close to the mounting plate 201 are connected to the adjusting block 213, and a plurality of limiting mechanisms 206 are also connected between the pressing mechanism 202 and the cutting tool 205.

[0023] This embodiment is implemented as follows: in actual use, since the width of the cutting tool 205 will be replaced according to the thickness of the metal plate, if the positions of the pressing mechanism 202 and the fixing plate 203 remain unchanged, it will be inconvenient to replace. If the cutting tool 205 is too thick, it will also cause the pressing mechanism 202 and the fixing plate 203 to contact the two sides of the cutting tool 205, so that the cutting tool 205 cannot cut normally. At this time, the driving motor 208 can be used to drive the adjusting screw 207 to rotate. When the adjusting screw 207 rotates, the positive and negative threads of the same length on the outer side rotate, driving the respectively connected adjusting blocks 213 to rotate, and the two sides of the adjusting blocks 213 slide in the screw grooves 214 to limit the rotation of the adjusting blocks 213. In this way, the two adjusting blocks 213 drive the respectively connected pressing mechanisms 202 and the fixing plates 203 to move away from or close to each other, and at the same time, the fixing plates 203 and the pressing mechanism 202 cooperate with the hanging blocks 210 connected on the outer sides to slide in the hanging grooves 209, so as to achieve stable movement.

[0024] See also Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As a preferred embodiment of the present application, the pressing mechanism 202 includes a pressing plate 222, a pressing strip 216 and a telescopic spring 217.

Limiting blocks 218 are also arranged at both ends of the pressing strip 216 in the inner part of the buffer cavity 215, and the limiting blocks 218 abut against the inner eaves of the opening of the buffer cavity 215.

[0025] Furthermore, the height of the pressing mechanism 202 is higher than the height of the cutting tool 205 , and the height of the fixing plate 203 is higher than the height of the pressing mechanism 202 .

[0027] This embodiment is implemented as follows: during cutting, the first cutting cylinder 5 can control the cutting assembly 2 to contact the metal plate on the panel 9. At this time, since the height of the pressing mechanism 202 is higher than the height of the cutting tool 205, and the height of the fixed plate 203 is higher than the height of the pressing mechanism 202, the fixed plate 203 will first contact the metal plate to fix the metal plate for the first time, and then the second cutting cylinder 204 will work to push the cutting tool 205 out as a whole. During the pushing process, the pressing mechanism 202 contacts the metal plate before the cutting tool 205. During the continuous downward pressure of the second cutting cylinder 204, the pressing strip 216 inside the pressing mechanism 202 will drive the telescopic spring 217 to contract, and the pressing strip 216 will be retracted into the pressing plate 222. At this time, the cutting tool 205 continues to press down to cut the metal plate. At this time, the fixed plate 203 and the pressing strip 216 press on both sides of the incision to reduce warping. At the same time, the limit block 218 will limit the position of the pressing strip 216 to prevent it from falling off the pressing plate 222.

At this time, the metal sheet can be sent to the support table 1 as a whole to achieve rapid loading, and by pushing the clamping strip 801, it can contact the outer corner, so that the bottom support 806 can rotate according to the angle of the clamping strip 801, and the sheet can be slowly moved up and fit on the panel 9. Then, the clamping cylinder 807 can be used to push out the clamping plate 805 and fix the metal sheet to the outside of the panel 9.
