[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] like Figure 1-Figure 5 A punching device for a platen mold is shown, and the punching device includes a frame 1, and the top of the frame 1 is connected to a ceiling 101 through a support. Multiple groups of telescopic rods 102 are vertically installed on the ceiling 101, and a punching member 103 is installed at the end of each group of telescopic rods 102 for punching the workpiece. A number of straight rails parallel to each other are installed on the upper part of the frame 1, and a moving plate 2 is slidably connected to the straight rail. A screw nut mechanism 4 is installed on the frame 1, and is used to drive the moving plate 2 to move on the straight rail. Multiple groups of bearing plates 201 are detachably installed on the moving plate 2, and the bearing plates 201 are used to position the platen mold, and multiple groups of feed ports 203 are opened on the bearing plates 201. The roller 3 is horizontally rotatably connected in the built-in cavity of the frame 1, located below the straight rail, and the axis of the roller 3 is parallel to the straight rail. A driving member 305 is installed in the cavity of the frame 1 for driving the roller 3 to rotate. The material guide assembly includes a material guide plate 301 which is arranged on the side wall of the cavity of the frame 1 and is positioned lower than the roller 3, and a shovel plate 302 which is connected to the top of one end of the material guide plate 301 close to the roller 3. The shovel plate 302 extends obliquely toward the roller 3 and fits against the outer wall of the roller 3, so as to scrape off the waste material attached to the outer wall of the roller 3 and guide it to the material guide plate 301.

[0037] Driven by the screw nut mechanism 4, the movable plate 2 can move smoothly from one end of the straight rail to the other end. Considering the actual processing needs, a production line is usually equipped with multiple punching stations, corresponding to each punching member 103 on the ceiling 101. During the movement, the movable plate 2 will stop accurately at each punching station in turn. At the same time, multiple sets of carrier plates 201 can be installed on a movable plate 2 so that multiple workpieces can be processed at the same time, which greatly improves the processing efficiency.

[0038] Screw nut mechanism 4

[0039] The screw-nut mechanism 4 includes a motor 401 and a screw rod 402 that is transmission-connected to the motor 401. The screw rod 402 forms a screw-nut pair transmission match with the moving plate 2. The motor 401 is configured to drive the screw rod 402 by rotation, thereby realizing the linear displacement of the moving plate 2 along the straight rail. With this precise transmission system, the moving plate 2 can accurately stay at each punching station according to the set program, ensuring the accuracy of the punching operation.

[0040] Waste treatment process

[0041] The waste generated by the punching member 103 after punching can fall onto the roller 3 in the inner cavity of the frame 1 through the gap between the straight rails. Since the roller 3 is long enough, it can receive the waste generated by all the punching stations on a production line. The roller 3 rotates axially toward the shovel plate 302 so that the waste is shoveled off by the shovel plate 302 and guided out through the guide plate 301. A guide plate 304 is provided below the straight rail, and a guide channel is formed between the guide plate 304 and the straight rail. The outlet of the guide channel corresponds to the upper surface of the roller 3. The plate surface of the guide plate 304 is inclined at 15°-45° to the plane of the straight rail, which is used to concentrate the waste generated by punching to the bearing area of ​​the roller 3, further optimizing the waste collection path and improving the waste treatment efficiency.

[0042] Carrier plate 201 connection and positioning

[0043] The carrier plate 201 and the movable plate 2 are connected in a detachable manner, including but not limited to bolt connection and snap connection. Each set of carrier plates 201 is provided with a plurality of positioning members 202, which are positioning pins or elastic clamps, and are used to achieve accurate positioning of the workpiece on the carrier plate 201, ensuring that the workpiece will not be displaced during the processing, thereby ensuring the dimensional accuracy of the product.

[0044] Shovel board 302 auxiliary structure

[0045] A brush 303 assembly is provided at the edge where the shovel plate 302 contacts the roller 3. The brush 303 assembly includes a mounting base fixed to the shovel plate 302 and bristles distributed in an array. The bristles are made of flexible and wear-resistant material, and the free ends of the bristles form elastic contact with the outer wall of the roller 3, so as to enhance the waste scraping effect and reduce mechanical wear, thereby extending the service life of the shovel plate 302 and the roller 3.

[0046] During the working process of this embodiment:

[0047] Feeding

[0048] The plate to be processed is placed on the carrier plate 201 and accurately positioned using the positioning member 202. The motor 401 is started, and the movable plate 2 is driven to move on the straight rail through the screw nut mechanism 4, so that the carrier plate 201 and the plate are transported to the first punching position.

[0049] punching

[0050] The telescopic rod 102 is started to drive the punching member 103 to move downward to punch the plate. The waste generated by the punching passes through the discharge port 203 on the carrier plate 201 and the gap between the straight rails, and is guided by the guide plate 304 to fall onto the roller 3. After completing the punching of this station, the mobile plate 2 continues to move to the next punching station, and the above punching operation is repeated until it passes through each punching member 103 on the ceiling 101 and completes all the preset punching processes.

[0051] forming

[0052] After punching is completed, the movable plate 2 continues to move, and the punched plate is transported to the forming mold position, and a forming operation is performed through a corresponding mold to form the plate into a desired shape.

[0053] Blanking

[0054] The product after forming is separated from the mold by the blanking process to complete the whole processing process. In the whole process, the roller 3 continues to rotate, and the waste material attached to its outer wall is scraped off by the shovel plate 302, and is exported by the guide plate 301 to avoid the waste material accumulation.
