[0002] Plastic products are a general term for daily necessities, industrial products, etc. processed mainly with plastics, including products of all processes such as injection molding and thermoforming with plastics as raw materials. During the production and processing of plastic products, in order to facilitate subsequent assembly, punching treatment is often required, so a punching machine is needed. The Chinese authorized utility model patent (Publication No.: CN219726494U) discloses a punching machine. By setting a push block, a connecting column and a mounting groove, the outer plug is used to push the push rod to further drive the push block to push the arc-shaped slider back into the second spring groove, further making the connecting column disengage from the mounting groove, further removing the punching head, and then inserting punching heads of different specifications, which can realize punching operations of different specifications and has stronger adaptability.

[0003] However, the above device still has some deficiencies in use: due to the material characteristics of plastic parts themselves, such as low hardness and good toughness, etc., they are prone to deformation under the influence of external forces during processing. Especially during the clamping process, if the clamping force is too large, plastic parts are extremely likely to be damaged due to uneven stress. Therefore, in view of the above situation, a punching machine with a cleaning structure for plastic part processing is proposed. Content of the Utility Model

[0010] Preferably, the workbench is in an inverted "U" shape, and a row of discharge grooves communicating with the aggregate hopper are formed through the top of the workbench.

[0011] Preferably, a through hole is formed through the top of the support block, and the through hole is matched with the moving end of the first cylinder.

[0012] Preferably, the bottom of the mounting post has an assembly groove, and the spring is arranged in the assembly groove.

[0013] Preferably, a rubber pad is arranged at the bottom of the positioning rod, and the rubber pad is hemispherical.

[0022] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Refer to Figures 1-4 , a punching machine with a cleaning structure for plastic part processing, including a workbench 1, and a pair of positioning mechanisms 2 are arranged on the top of the workbench 1. As Figure 1 shown, a support frame 3 is arranged on the pair of positioning mechanisms 2, and a punching assembly 4 is arranged on the support frame 3.

[0024] Further, the punching assembly 4 includes a second cylinder arranged on the top of the support frame 3. After passing through the support frame 3, the second cylinder is fixedly connected with a punching plate, and a punching head is arranged at the bottom of the punching plate.

[0025] Furthermore, the support frame 3 is composed of four columns and a top plate fixed on the tops of the four columns. The top plate has a through hole for cooperating with the moving end of the second cylinder.

[0026] Still further, four telescopic rods are arranged at the bottom of the top plate. The telescopic rods are composed of a main rod with a stepped groove and a stepped rod. The bottom of the stepped rod is fixedly connected with the punching plate.

[0027] The positioning mechanism 2 includes a support block 201. A first cylinder 202 is arranged on the top of the support block 201. After the moving end of the first cylinder 202 passes through the support block 201, it is fixedly connected with a pressing plate 203. Specifically, a through hole is formed through the top of the support block 201, and the through hole cooperates with the moving end of the first cylinder 202. Two rows of mounting posts 204 are arranged at the bottom of the pressing plate 203.

[0028] A spring 205 is arranged inside the mounting post 204. Specifically, an assembly groove 2040 is formed at the bottom of the mounting post 204, the spring 205 is arranged in the assembly groove 2040, the bottom of the spring 205 is fixedly connected with a positioning rod 206, and a rubber pad is arranged at the bottom of the positioning rod 206. The rubber pad is hemispherical.

[0029] During use, first place the plastic part to be processed flat on the workbench 1. Then, turn on the switches of a pair of first cylinders 202 to make them work synchronously. When the first cylinders 202 work, the pressing plate 203 descends. When the pressing plate 203 descends, the positioning rods 206 descend to contact the surface of the plastic part. The longitudinal positioning can distribute the clamping force more evenly, reduce the deformation and damage of the plastic part caused by uneven force, thereby improving the qualified rate of the product. And when the surface of the plastic part is uneven, the positioning rods 206 continue to descend at the concave surface of the plastic part. After the positioning rods 206 at other parts contact the plastic part, they will squeeze the springs 205, causing the positioning rods 206 to contract towards the assembly grooves 2040, with high adaptability and being able to flexibly handle the uneven surface of the plastic part. Through adaptive adjustment, it ensures stable clamping of plastic parts with different shapes and sizes, greatly improving the versatility and processing efficiency of the equipment.

[0030] A material collecting hopper 5 is arranged at the bottom of the workbench 1. At the same time, in order to collect the debris after punching, as Figure 1 and Figure 2 shown, the workbench 1 is in an inverted "U" shape, and a row of discharge grooves communicating with the material collecting hopper 5 are formed through the top of the workbench 1.

[0031] A feeding pipe 6 is connected to the material collecting hopper 5. The feeding pipe 6 is made of rubber material. A pair of collecting boxes 7 are placed at the bottom of the workbench 1. A clamping plate 8 is arranged on each of the pair of collecting boxes 7. Specifically, the clamping plate 8 has a clamping groove for clamping the feeding pipe 6 to realize the limit of the feeding pipe 6.

[0032] During the punching operation of the plastic part, the discharge grooves can guide the debris generated by punching into the material collecting hopper 5, and then convey it to the collecting box 7 through the feeding pipe 6 for collection. And when the debris collected in one of the collecting boxes 7 needs to be cleaned, the feeding pipe 6 can be clamped on the clamping plate 8 of the other collecting box 7, thereby ensuring the continuous processing of the plastic part while completing the collection and treatment of the debris and ensuring the continuity of processing.

[0033] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
