Description

Technical Field

[0001] This utility model belongs to the technical field of plastic parts cutting and processing devices, and specifically relates to a plastic parts processing and cutting device. Background Technology

[0002] During the production and processing of plastic products, there is a cutting process, which mainly involves cutting long plastic parts into smaller products of fixed length. A common method for cutting plastic parts is mechanical cutting, which mainly uses pneumatic or hydraulic drive as a power source and achieves cutting through the shearing force of cutting tools or mechanical structures.

[0003] When a pneumatically driven cutter cuts round plastic tubes, the round plastic tube is manually placed on the lower die, and the cutting device is activated, causing the cylinder to drive the cutter downwards to cut the round plastic tube. In the above operation, manually placing the round plastic tube is inaccurate and may result in the round plastic tube being skewed, leading to a tilted cut surface. In addition, a fixed round plastic tube sleeve is usually used to limit the round plastic tube and prevent it from being skewed. However, for round plastic tubes of different diameters, a fixed single round plastic tube sleeve cannot accommodate different round plastic tubes. Existing pneumatically driven cutting devices do not have a limit on the round plastic tube and lack an auxiliary positioning design with adjustable angle to adapt to round plastic tubes of different diameters, which needs to be improved.

[0004] Existing pneumatically driven cutting devices for cutting round plastic parts have problems such as the lack of a limiting design for the round plastic parts and an adjustable angle to accommodate round tubes of different diameters. To address this, this application proposes a plastic part processing and cutting device. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a plastic part processing and cutting device, including a pneumatic mechanical cutting assembly, including a cutting bracket and a lower mold component. The lower mold component includes a horizontal arm 21 and a cutting lower mold 22 fixedly connected by screws, combined with a downward... Figure 1When cutting round plastic tube parts, one end of the round plastic tube part is placed on the lower cutting die 22. When the cylinder 13 on the manually driven cutting bracket is running, the lifting plate 14 and the cutting blade 15 move down. The moving cutting blade 15 cuts the round plastic tube part, achieving the purpose of cutting the workpiece. The mechanical cutting method of using the cylinder 13 to drive the cutting blade 15 to cut the plastic part is a conventional technical means, and this application will not elaborate further. The moving component includes a sliding table 32 and a guide rail 31 that are slidably connected. The support plate 33 is fixed to the slide table 32 by screws. The slide table 32 moves along the length of the guide rail 31 towards the fixed frame 12. The positions of the support plate 33 and the limiting cylinder 6 can be manually adjusted, facilitating manual adjustment of the angle of the limiting cylinder 6. The limiting component includes a support plate 51 perpendicular to the support plate 33, a limiting ring 52 welded to the top of the support plate 51, and a locking screw 53 penetrating the support plate 51. The limiting ring 52 serves to limit and support the limiting cylinder 6. When the locking screw 53 is tightened, The locking screw 53 secures the fixing plate 71, keeping the fixing ring 7 and the limiting cylinder 6 stable and preventing the fixing ring 7 from deflecting. The adjustable station frame for limiting plastic pipe fittings includes the limiting cylinder 6 and the fixing ring 7 fixed by screws, the fixing plate 71 welded to the fixing ring 7, and a cylindrical frame 8 installed inside the limiting cylinder 6. The cylindrical frame 8 has a circular tube groove 81 and a plate groove 82 on its surface. The cylindrical frame 8 serves to limit the circular plastic pipe fittings during the cutting process. When the tube breaks, the round plastic part passes through the round tube groove 81 with the corresponding diameter, which limits the round plastic part and prevents it from deflecting. In addition, the angle of the limiting cylinder 6 and the cylindrical frame 8 can be manually adjusted to change the position of the round tube groove 81 and the plate groove 82 on the cylindrical frame 8, so that the round tube groove 81 can adapt to round plastic parts with different diameters and plate-shaped plastic parts with different thicknesses. The geometry of the round tube groove 81 and the plate groove 82 can be designed according to the actual situation to suit different plastic parts.

[0028] In this embodiment, the cutting bracket includes a fixedly connected base 11 and a fixed frame 12, a cylinder 13 passing through the fixed frame 12, a lifting plate 14 fixed by bolts, and a cutting tool 15. The cutting tool 15 is opposite to the cutting lower mold 22. A guide post a is fixedly connected between the base 11 and the "U"-shaped fixed frame 12. Sleeves are welded to both ends of the lifting plate 14. The guide post a passes through the sleeve and limits the lifting plate 14, so that the lifting plate 14 is limited during the lifting process.

[0029] In this embodiment, the guide rail 31 has a "T" shaped structure, and the slide table 32 has a groove that mates with the guide rail 31. The guide rail 31 is fixed to the base 11 by screws. A connecting plate 41 is fixed to the opposite surface of the slide table 32 by screws. A hand-tightened Torx screw 42 passes through one end of the connecting plate 41. When the hand-tightened Torx screw 42 is tightened, it reinforces the connecting plate 41, keeping the connecting plate 41 fixed on the surface of the base 11.

[0030] In this embodiment, the limiting ring 52 is sleeved on the outside of the limiting cylinder 6, and the fixing ring 7 is located between the opposing limiting rings 52. The inner and outer diameters of the limiting ring 52 and the fixing ring 7 are the same. The fixing plate 71 has a screw hole through which the locking screw 53 passes. When the locking screw 53 is tightened, the locking screw 53 fixes the fixing plate 71, so that the fixing ring 7 and the limiting cylinder 6 remain stable and prevent the fixing ring 7 from deflecting.

[0031] In this embodiment, there are 5 circular tube grooves 81 with different diameters. The diameter difference between two adjacent circular tube grooves 81 is 5 mm. There are 2 plate grooves 82 with different thicknesses. The angles of the limiting cylinder 6 and the cylindrical frame 8 are manually adjusted to change the positions of the circular tube grooves 81 and plate grooves 82 on the cylindrical frame 8, so that the circular tube grooves 81 can adapt to circular tube plastic parts with different apertures and plate plastic parts with different thicknesses. The geometry of the circular tube grooves 81 and plate grooves 82 can be designed according to actual conditions to suit different plastic parts. The plane on the top surface of the cutting lower mold 22 is surface B. The circular tube grooves 81 and plate grooves 82 are tangent to the curved surface C, which is annular. When the angles of the limiting cylinder 6 and the cylindrical frame 8 are changed, the corresponding plastic parts supported by the changed circular tube grooves 81 and plate grooves 82 are in contact with the surface of the cutting lower mold 22, avoiding any gap between the plastic parts and the cutting lower mold 22.

[0032] Working principle and usage process of this utility model:

[0033] When cutting round plastic tube parts, one end of the round plastic tube part is placed on the cutting lower die 22. When the cylinder 13 on the cutting bracket is driven manually, the lifting plate 14 and the cutting cutter 15 move down. The lowered cutting cutter 15 cuts the round plastic tube part, thus achieving the purpose of cutting the workpiece.

[0034] When placing the round plastic part, the round plastic part passes through the round groove 81, which restricts the round plastic part and prevents the round plastic part from being skewed.

[0035] When cutting plastic parts with different apertures, manually loosen the locking screw 53 and adjust the angle of the limit cylinder 6;

[0036] The angles of the limiting cylinder 6 and the cylindrical frame 8 can be manually adjusted to change the positions of the circular tube groove 81 and the plate groove 82 on the cylindrical frame 8, so that the circular tube groove 81 can adapt to circular tube plastic parts with different apertures and plate plastic parts with different thicknesses. The geometry of the circular tube groove 81 and the plate groove 82 can be designed according to the actual situation to suit different plastic parts.

[0037] In summary, the plastic part cutting device of this application has an auxiliary positioning design that limits the positioning of round tube plastic parts and allows for adjustable angles to adapt to round tubes of different diameters. By manually adjusting the angles of the limiting cylinder 6 and the cylindrical frame 8, the positions of the round tube groove 81 and the plate groove 82 on the cylindrical frame 8 can be changed, so that the round tube groove 81 can adapt to round tube plastic parts of different diameters and plate-shaped plastic parts of different thicknesses. It has the function of limiting the positioning of round tube plastic parts, and the limiting cylinder 6 can be manually adjusted to adapt to plastic parts of different diameters.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
