Description

Technical Field

[0001] The utility model relates to a pipe processing tool, in particular to a pipe special-shaped processing lining tool. Background Art

[0002] With the continuous development of polymer materials, plastic pipes are used more and more widely, such as in the medical and industrial production industries. Pipes often need to be connected for use. In order to facilitate connection and use, the end face or side of the pipe needs to be shaped. When the pipe wall thickness is thin or the specifications and sizes are diverse, it will cause difficulties in special-shaped processing. At present, the commonly used methods in the special-shaped processing process are blade cutting, heat setting, etc., and the accuracy is difficult to guarantee when there is no lining inside the pipe. The existing lining tool is an integrated design. For the processing of pipes of different specifications, the corresponding lining tool needs to be re-made. It has narrow applicability, is inconvenient to use, and has low processing efficiency. Therefore, a lining tool for special-shaped processing of pipes is needed, and the tool can be combined and adjusted according to the specifications of the pipe and the processing shape. Utility Model Content

[0004] A lining tool for processing special-shaped pipes comprises two parts, a pipe and a lining. The lining part is composed of a pipe lining part, a special-shaped lining part and a clamping part which are axially connected in sequence. The pipe lining part is an equal-diameter columnar structure, and a limiting hole is axially arranged at the connecting end with the special-shaped lining part. A fixing pin is axially arranged at the connecting end with the pipe lining part, and the limiting hole matches the fixing pin.

[0005] A limiting hole is axially arranged at the connection end between the special-shaped lining part and the clamping part, a fixing pin is axially arranged at the connection end between the clamping part and the special-shaped lining part, and the limiting hole matches the fixing pin.

[0006] A buckle is protruding from the inner wall of the limiting hole and matches with a buckle groove concavely arranged on the surface of the positioning pin.

[0007] The surface of the clamping part is frosted to increase the friction of the clamping part.

[0008] The surfaces of the pipe lining part, the special-shaped lining part and the clamping part are provided with coatings.

[0009] The limiting hole and the fixing pin are wedge-shaped connection structures.

[0010] The surface of the inner lining of the pipe is provided with scale lines in the axial direction to determine the processing position.

[0011] The edges of both ends of the pipe lining part, the special-shaped lining part and the clamping part are rounded structures.

[0012] The special-shaped lining part is a truncated cone structure.

[0013] Compared with the prior art, the beneficial effects are as follows: the utility model is a split structure, can be freely combined and adjusted according to the specifications of the pipe, can be reused many times, saves manpower and material resources, and has high processing efficiency; the inner lining part of the pipe is also provided with scale lines to improve the processing accuracy, and the edge of the connecting end is a rounded structure, which can effectively protect the pipe from damage; the connection method of the limit hole and the fixing pin is adopted to effectively improve the connection firmness.

Implementation

[0026] In order to facilitate ordinary technicians in this field to understand and implement the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. The following examples are used to illustrate the utility model, but it should be understood that the protection scope of the utility model is not limited by the specific implementation methods. Example

[0027] like Figure 1-2 As shown, the special-shaped lining part 2 is a truncated cone structure. The pipe lining part 1, the special-shaped lining part 2 and the clamping part 3 are assembled together. The pipe lining part 1 and the special-shaped lining part 2 are lined inside the pipe through the clamping part 3. The tool can cut from the larger diameter position of the side of the special-shaped lining part 2 to the smaller diameter position, so that the pipe forms a truncated cone or a conical structure, or a heating device is used to heat the pipe so that the pipe forms a truncated cone or a conical structure at the lining part of the special-shaped lining part 2, which is convenient for connection with a pipe with a smaller diameter. Example

[0028] like Figure 3 As shown, the special-shaped lining part 2 is an end face beveled structure. The pipe lining part 1, the special-shaped lining part 2 and the clamping part 3 are assembled together. The pipe lining part 1 and the special-shaped lining part 2 are lined inside the pipe through the clamping part 3. The tool cuts the pipe according to the shape of the special-shaped lining part 2, and processes the pipe into an oblique cut at a certain angle. Example

[0029] like Figure 4 As shown, the special-shaped lining part 2 is an L-shaped structure. The pipe lining part 1, the special-shaped lining part 2 and the clamping part 3 are assembled together. The pipe lining part 1 and the special-shaped lining part 2 are lined inside the pipe through the clamping part 3. The tool cuts the pipe according to the shape of the special-shaped lining part 2 and processes the pipe into an L-shaped incision. Example

[0030] like Figure 5 As shown, the special-shaped lining part 2 is an hourglass-shaped structure. The pipe lining part 1, the special-shaped lining part 2 and the clamping part 3 are assembled together. The pipe lining part 1 and the special-shaped lining part 2 are lined inside the pipe through the clamping part 3. The tool cuts the pipe according to the shape of the special-shaped lining part 2 to form arc-shaped side holes on both sides of the pipe wall without affecting the diameter of the pipe. Example

[0031] like Figure 6 As shown, the special-shaped lining part 2 is an axial three-groove structure. The pipe lining part 1, the special-shaped lining part 2 and the clamping part 3 are assembled together. The pipe lining part 1 and the special-shaped lining part 2 are lined inside the pipe through the clamping part 3. The tool cuts the pipe according to the axial groove shape of the special-shaped lining part 2 to form a pipe groove. Other pipes matching the pipe groove can be placed in the pipe groove, and the two are connected together using a heating device. Example

[0032] The clamping part 3 is frosted to increase friction, making it easier to hold and plug in and out. Example

[0033] The edges at both ends of the pipe lining part 1, the special-shaped lining part 2 and the clamping part 3 are rounded structures, so that the pipe will not be scratched when the tool penetrates into the pipe. Example

[0034] The cross-sectional shape of the special-shaped lining part 2 can be designed and processed according to the shape of the pipe that needs to be processed in a special-shaped manner, such as round, oval, D-shaped, etc. Example

[0035] A limiting hole is axially arranged at the connecting end of the special-shaped lining part 2 and the clamping part 3, and a fixing pin is axially arranged at the connecting end of the clamping part 3 and the special-shaped lining part 2. The limiting hole matches the fixing pin, and a buckle is protruding from the inner wall of the limiting hole, which matches the groove concavely arranged on the surface of the positioning pin. The groove is an L-shaped groove. When in use, the buckle is inserted to the bottom from the opening of the axial groove of the L-shaped groove, and then rotated circumferentially to lock the buckle in the circumferential groove of the L-shaped groove.
