In addition, as shown in FIG. Figure 1 , Figure 2 and Figure 4 As shown, an adjustment plate 7 is fixedly provided at the bottom of the top plate 2 , and the adjustment plate 7 is located obliquely above the second limit seat 6 away from the first limit seat 5 .

[0027] In addition, in the present application, a positioning assembly is provided on the side of the second limit seat 6 away from the first limit seat 5; the positioning assembly includes a fixing plate 17, a positioning rod 15 and a positioning spring 16; Figure 1 As shown, the fixed plate 17 is fixed on the base plate 1 and is located on the side of the second limit seat 6 away from the first limit seat 5, and there is a space between the fixed plate 17 and the second limit seat 6 for the adjustment plate 7 to be inserted; the positioning rod 15 is arranged along the length direction of the base plate 4, and one end of the positioning rod 15 is provided with a fixed head 150, and the other end thereof passes through the fixed plate 17, and the end portion thereof is fixedly connected to the second limit seat 6; the positioning spring 16 is sleeved on the positioning rod 15, and one end of the positioning spring 16 is fixedly connected to the fixed head 150, and the other end is fixedly connected to the side wall of the fixing plate 17 away from the second limit seat 6.

[0028] In this application Figure 4 and Figure 5 As shown, the profile 18 is located between the first limit seat 5 and the second limit seat 6. When preparing for cutting, the hydraulic cylinder 3 drives the top plate 2 to descend, that is, moves toward the direction close to the bottom plate 1, and then the cutting knife 8 descends, and the adjustment plate 7 also descends. Among them, a sloped transition portion 10 is provided on the side of the top of the second limit seat 6 away from the first limit seat 5. The adjustment plate 7 is located obliquely above the side of the second limit seat 6 away from the first limit seat 5. During the descent of the adjustment plate 7, the side edge of its bottom close to the second limit seat 6 first abuts against the transition portion 10, and is gradually inserted into the space between the fixed plate 17 and the second limit seat 6 through the transition portion 10 (as shown in FIG. 1 ). Figure 4 arrive- Figure 5 process) and to Figure 4 The right side of the second limit seat 6 is pushed to make the second limit seat 6 approach the first limit seat 5, thereby clamping the profile 18 to form Figure 5 The second limit seat 6 is Figure 4 When the top plate 2 moves to the right, the positioning rod 15 will be driven to move to the right, and the positioning spring 16 will be compressed. At the same time, during the descent of the top plate 2, the cutting knife 8 will also descend, and will be located at a position between the first limit seat 5 and the second limit seat 6. It is worth noting that in this process, the bottom of the adjusting plate 7 will first contact the second limit seat 6, and squeeze the second limit seat 6 first, so that the second limit seat 6 and the first limit seat 5 clamp the profile 18, and then when the cutting knife 8 contacts the profile 18, the profile 18 has been clamped, and the cutting knife 8 can cut the profile 18 (in this application, the cutting knife 8 is driven by the hydraulic cylinder 3 to move downward and punch the profile 18).

[0029] In the present application, after the cutting is completed, the cutting knife 8 and the adjusting plate 7 are raised under the drive of the hydraulic cylinder 3, and the adjusting plate 7 is separated from the space between the fixing plate 17 and the second limiting seat 6, and the second limiting seat 6 is no longer squeezed. In addition, due to the setting of the positioning assembly, the positioning spring 16 drives the positioning rod 15 to move away from the first limiting seat 5, and the positioning rod 15 drives the second limiting seat 6 to move away from the first limiting seat 5, thereby widening the width between the second limiting seat 6 and the first limiting seat 5, which can facilitate the movement of the profile 18.

[0030] This application Figure 2 As shown, the adjusting plate 7 is provided with an open passage 11 for the positioning rod 15 to pass through. When the adjusting plate 7 descends, the positioning rod 15 can be located in the open passage 11 and will not hinder the descending of the adjusting plate 7.

[0031] In addition, in the present application, a cutting groove 12 is provided on the base plate 4 for inserting the cutting knife 8 to avoid damage to the blade of the cutting knife 8.
