[0036] Embodiment:

[0037] Please refer to Figure 1 - Figure 8 A pressing mechanism for a material cutting machine, which includes a lower die table 101 and a stamping die base 102 provided on a material cutting machine body 1. A cutting head 103 for cutting materials is provided on the stamping die base 102. Collection frames 2 are provided at both ends of the lower die table 101 for concentrating materials, and an inner baffle 201 is provided at the inner end of the opening of the collection frame 2.

[0038] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 The pressing mechanism of the material cutting machine in this application is mainly composed of structures such as a material cutting machine body 1, a lower die table 101, a stamping die base 102, and a cutting head 103 that cooperate with each other. Among them, the lower die table 101 is installed on the base of the material cutting machine body 1. The stamping die base 102 can move downward under the drive of a top cylinder along the slide rods around the material cutting machine body 1. The cutting heads 103 are respectively installed at the front and rear ends of the bottom of the stamping die base 102. When the stamping die base 102 is pressed onto the lower die table 101, the cutting heads 103 are used for trimming the edges of the workpiece. During cutting, since the cutting heads 103 are driven by the stamping die base 102 to press downward for edge trimming, when trimming the edges, collection frames 2 with openings facing the cutting heads 103 are respectively provided at the front and rear ends of the connection between the lower die table 101 and the stamping die base 102 when the stamping die base 102 moves downward. During downward edge trimming, the immediately separated edge materials can run out to the side and enter through the openings of the collection frames 2. The inner baffle 201 is installed below the opening of the collection frame 2 and is designed as an inward slope to prevent the edge materials from rising after entering the interior of the collection frame 2, so as to timely collect the cut edge materials during downward punching cutting, facilitating subsequent cleaning and other operations.

[0039] In some embodiments, the side of the collection box 2 of the present application that is far from the opening is designed with an outward arc. When the collection box 2 enters through its opening, the movement range of the side material can be increased to prevent it from running out.

[0040] Please refer to Figure 4 and Figure 6 In the present application, a bracket 3 and an elastic plate 301 are also provided. The bracket 3 is installed at the front and rear ends of the base of the cutting body 1 to support the collection box 2. The elastic plate 301 and the bracket 3 are integrally structured. The elastic plate 301 is made of metal material. While ensuring stability, the collection box 2 can be fixed on the outer wall of the lower die table 101 by stretching, so that the opening of the collection box 2 can better concentrate the side material. Among them, the elastic plate 301 is provided with an arc, so that it can completely fit with the end of the outer wall of the collection box 2 with an arc surface, better ensuring the stability of the contact. A pull ring 302 is installed on the outer wall of the elastic plate 301, which is convenient to move the pull ring 302 outward, so that the elastic plate 301 moves away from the collection box 2 to release the fixation of the collection box 2.

[0041] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In the present application, a side opening 4 and a side baffle 401 are also provided. The side opening 4 is opened on both sides of the collection box 2, and the side baffle 401 can cover the outside of the side opening 4 to block the side opening 4. When the side opening 4 is opened, it is convenient to observe the inside of the collection box 2.

[0042] The present application also provides a fixing frame 402 and a compression spring 403. The fixing frame 402 is symmetrically installed on both sides of the outer wall of the collection frame 2. After one end of the side baffle 401 is restricted between the fixing frame 402 and the collection frame 2, through the connection of the compression spring 403, the side baffle 401 can move inside the fixing frame 402. By moving the fixing frame 402 towards one end close to the fixing frame 402, under the drive of the acting force, when it is greater than the extrusion of the compression spring 403, the fixing frame 402 covering the side opening 4 is driven to move away, so as to open the side opening 4 and observe the inside of the collection frame 2. At the same time, opening the side opening 4 can also sort or remove the inner edge materials, improving the applicability. A limiting clamping plate 404 is installed at one end of the side baffle 401 moving inside the fixing frame 402, with one end of the compression spring 403 installed on the limiting clamping plate 404 and the other end connected to the inner wall of the fixing frame 402. The fixing frame 402 is arranged in the middle of the limiting clamping plate 404. When the side baffle 401 moves, the limiting clamping plate 404 always moves along the upper and lower ends of the fixing frame 402 to limit the moving side baffle 401. A handle 405 is installed at the corner of the outer wall of the side baffle 401, facilitating the overall movement of the side baffle 401 and improving the operation convenience.

[0043] The present application also provides a sleeve plate 5 and a positioning rod 501. When the compression spring 403 is in the initial state and drives the side baffle 401 to return to its original state, since the sleeve plate 5 and the side baffle 401 are of an integrated structure design, it can be pressed against the outer wall of the side baffle 401 under the drive of the elastic force of the compression spring 403. Among them, the positioning rod 501 is installed at the position on the outer wall of the lower die table 101 corresponding to the sleeve plate 5. When the side baffle 401 contacts the outer wall of the lower die table 101, the hole of the sleeve plate 5 can be driven to be sleeved outside the positioning rod 501 to further position the collection frame 2 on the side of the cutting machine body 1 and prevent it from shifting left and right after installation.

[0044] Please refer to Figure 4 and Figure 5 In the present application, an anti-slip layer 502 is also provided. When the sleeve plate 5 is pressed against the outer wall of the lower die table 101, a plurality of anti-slip layers 502 made of rubber material are evenly glued to its contact surface with the lower die table 101. When in contact, it can further increase the friction force of the contact surface, improve the stability, and at the same time, since the anti-slip layer 502 is made of rubber material, it can also protect the contact surface to a certain extent when the sleeve plate 5 hits the lower die table 101.

[0045] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the above principles, the embodiments of the present invention can have any deformation or modification.
