Description

Technical Field

[0001] This utility model relates to the field of vacuum copper bushing technology, and in particular to a shape-stabilizing and diameter-stabilizing vacuum copper bushing. Background Technology

[0002] Vacuum sizing copper sleeves are used in the shaping of plastic products. They are mainly used to shape the outer diameter and ensure the stability of the shape. The shaping material of the sizing sleeve is generally nylon (PA) material, which belongs to the category of strong vacuum sizing sleeves. Nylon tubes have the characteristics of high hardness and are shaped when exposed to water. Without vacuum shaping, the tube may become flat, irregular in shape, and have large dimensional fluctuations. Therefore, sizing sleeves are used in the manufacturing process to assist in production and ensure that the shape and outer diameter of the tube are kept stable.

[0003] In the current vacuum forming process for tube manufacturing, the front hole of the vacuum copper sleeve cannot effectively remove water when the front section is in a vacuum state, resulting in large fluctuations in water flow at the front section due to high water level. Furthermore, during the vacuum forming process in the rear section, uneven water removal in the water tank causes instability in the water film, resulting in water waves and splashes. Consequently, the outer diameter of the manufactured tube remains unstable, with large fluctuations in outer diameter and irregular shape. Therefore, a vacuum copper sleeve that can form and stabilize the diameter is needed. Utility Model Content

[0004] The purpose of this invention is to provide a shape-stabilizing vacuum copper sleeve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shape-stabilizing and diameter-stabilizing vacuum copper sleeve, comprising a copper sleeve head, a front section tube fixedly mounted on one side of the copper sleeve head, one end of the front section tube mounted on the copper sleeve head, an mounting block fixedly mounted on the other end of the front section tube, a rear section tube fixedly mounted on the other side of the mounting block, a first through hole opened on the copper sleeve head, a first chamfered hole opened on the first through hole, a second through hole opened on the front section tube, a second chamfered hole opened on the second through hole, and a third chamfered hole opened on the rear section tube.

[0006] Preferably, the copper sleeve, the front tube, and the rear tube are all provided with tube-making holes.

[0007] Preferably, the mounting block has mounting threads, and the rear section of the pipe has wire cutting holes.

[0008] The beneficial effects of this utility model are:

[0009] In this invention, the arrangement of the first through hole, the first chamfered hole, the second through hole, the second chamfered hole and the third chamfered hole can reduce the fluctuation of water flow inside and outside the front and rear sections of the pipe, thereby forming a stable water film, making the processed pipe body more round and the dimensions more accurate.

[0013] 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.

[0014] Example:

[0015] like Figure 1-2 As shown, this embodiment provides a shapeable and diameter-stabilized vacuum copper sleeve, including a copper sleeve head 1. A front section tube 2 is fixedly installed on one side of the copper sleeve head 1. One end of the front section tube 2 is installed on the copper sleeve head 1. An installation block 3 is fixedly installed on the other end of the front section tube 2. A rear section tube 4 is fixedly installed on the other side of the installation block 3. A first through hole 5 is opened on the copper sleeve head 1. A first chamfer hole 6 is opened on the first through hole 5. A second through hole 7 is opened on the front section tube 2. A second chamfer hole 8 is opened on the second through hole 7. A third chamfer hole 9 is opened on the rear section tube 4.

[0016] The pipe body is first pre-shaped in the front section pipe 2. The setting of the first chamfered hole 6 and the second chamfered hole 8 will make its vacuum water absorption capacity larger. The pipe body will continue to be processed and then undergo secondary shaping through the rear section pipe 4. The setting of the third chamfered hole 9 will also increase the water flow rate from the inside to the outside of the rear section pipe 4, ensuring that the water film generated in the channel during vacuum sizing can be stable.

[0017] The copper sleeve head 1, the front tube 2 and the rear tube 4 are all provided with tube making holes 10, the mounting block 3 is provided with mounting threads 11, and the rear tube 4 is provided with wire cutting holes 12.

[0018] The pipe hole 10 allows the pipe body to pass through, the installation thread 11 can fix the copper sleeve body in the small water tank, and the wire cutting hole 12 can extract the water in the rear section of the pipe 4, so that a water film is formed in the rear section of the pipe 4.

[0019] Working principle: In use, first install the mounting block 3 in the small water tank at the front end of the vacuum water tank, rotate the copper sleeve head 1, and use the mounting thread 11 to fix the mounting block 3 in the small water tank. Then start the vacuum water tank. The tube body will be pre-shaped in the front section tube 2. The vacuum water tank will extract the water in the front section tube 2, so that a water film is formed in the front section tube 2. The setting of the first chamfer hole 6 and the second chamfer hole 8 will make the vacuum water suction capacity larger, preventing the water flow from fluctuating too much due to insufficient water extraction. The tube body will continue to be processed through the rear section tube 4 for secondary shaping. The setting of the wire cutting hole 12 will extract the water. The water extraction will be uneven, causing the water film to be unstable and producing water waves and splashes, resulting in fluctuations in the outer diameter. The setting of the third chamfer hole 9 will also increase the water flow inside and outside the rear section tube 4, ensuring that the water film generated in the channel during vacuum sizing can be stable. This can effectively solve the problems of large water flow fluctuations and unstable water film, making the processed tube body more round and the dimensions more accurate.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
