Technical Field

[0001] The utility model relates to the technology of pipe processing field, in particular to an adjustable pipe shrinking machine. Background Art

[0002] Automobiles are the most important means of transportation for people to travel now and have entered millions of families. Due to the large number of internal parts of automobiles, the automobile processing industry is growing stronger and stronger; various pipelines are required in automobile parts. When a pipeline is spliced and installed with other pipelines, a reaming operation needs to be performed on one end of it.

[0003] In the existing pipe shrinking machines, a pipe shrinking hole with a required diameter is opened on the pipe shrinking machine, and then the pipe shrinking head corresponds to the end of the round pipe and then presses towards the round pipe to complete the pipe shrinking processing. The pipe shrinking hole on the existing pipe shrinking machine is set with a single diameter, and it can only perform pipe shrinking processing for specific sizes, with great limitations in use. Moreover, when performing pipe shrinking processing for different products, it is necessary to design multiple pipe shrinking machines with different sizes, increasing the processing cost of pipe shrinking. Therefore, it is necessary to further improve the structure of the existing pipe shrinking machine. Summary of the Utility Model

[0004] In view of this, aiming at the deficiencies existing in the prior art, the main purpose of the utility model is to provide an adjustable pipe shrinking machine, which can effectively solve the problems of the existing pipe shrinking machine with a single size, great limitations in use, and high processing cost when dealing with products of different sizes.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An adjustable pipe shrinking machine includes a base, a pipe shrinking seat, a driving mechanism, a first pipe shrinking head, and a second pipe shrinking head; the pipe shrinking seat is arranged on the base so as to be able to move back and forth horizontally, and a first pipe shrinking hole is recessed and formed on the outer end surface of the pipe shrinking seat; the driving mechanism is arranged on the base and drives the pipe shrinking seat to move back and forth; the first pipe shrinking head is detachably arranged at the outer end of the pipe shrinking seat, a second pipe shrinking hole corresponding to the first pipe shrinking hole penetrates through the first pipe shrinking head, and the diameter of the second pipe shrinking hole is smaller than that of the first pipe shrinking hole; the second pipe shrinking head is detachably arranged at the outer end of the first pipe shrinking head, and a third pipe shrinking hole corresponding to the second pipe shrinking hole penetrates through the second pipe shrinking head, and the diameter of the third pipe shrinking hole is smaller than that of the second pipe shrinking hole.

[0007] As a preferred solution, two mounting plates arranged symmetrically front and back are provided on the base, a horizontally extending sliding groove is formed between the two mounting plates, and the pipe shrinking seat is matched with the sliding groove and slides back and forth along the extending direction of the sliding groove.

[0008] As a preferred solution, the inner side walls of the two mounting plates are both provided with laterally extending slide rails, and the front and rear side walls of the pipe shrinking seat are respectively provided with sliding seats that cooperate with the slide rails. The pipe shrinking seat moves back and forth laterally along the slide rails through the cooperation of the sliding seats and the slide rails.

[0009] As a preferred solution, a plurality of first fixing holes arranged at equal angles are formed in the outer end face of the pipe shrinking seat. The first pipe shrinking head includes a main body portion and a fixing portion integrally extending outward from one end of the main body portion facing the pipe shrinking seat. A first fixing bolt is provided on the fixing portion, and the first pipe shrinking head is detachably arranged on the pipe shrinking seat through the cooperation of the first fixing bolt and the first fixing hole.

[0010] As a preferred solution, a second fixing hole is formed in the outer end of the first pipe shrinking head, and a third fixing hole that cooperates with the second fixing hole is formed in the second pipe shrinking head. A second fixing bolt sequentially passes through the third fixing hole and the second fixing hole to detachably arrange the second pipe shrinking head at the outer end of the first pipe shrinking head.

[0011] As a preferred solution, a guiding surface is provided at the outer end opening of the third pipe shrinking hole.

[0012] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:

[0013] It is formed by inwardly concaving the outer end face of the pipe shrinking seat to form a first pipe shrinking hole, and the first pipe shrinking head is detachably arranged at the outer end of the pipe shrinking seat in cooperation. A second pipe shrinking hole corresponding to the first pipe shrinking hole penetrates through the first pipe shrinking head, and the diameter of the second pipe shrinking hole is smaller than that of the first pipe shrinking hole; and the second pipe shrinking head is detachably arranged at the outer end of the first pipe shrinking head, and a third pipe shrinking hole corresponding to the second pipe shrinking hole penetrates through the second pipe shrinking head, and the diameter of the third pipe shrinking hole is smaller than that of the second pipe shrinking hole; so that through the first pipe shrinking hole, the second pipe shrinking hole and the third pipe shrinking hole with different diameters, when processing products with different diameters, it can be achieved by disassembling and assembling the first pipe shrinking head and the second pipe shrinking head, thereby meeting the processing of more size products, having less use limitations, and at the same time, there is no need to design multiple pipe shrinking machines, effectively reducing the processing cost.

[0029] Please refer to Figures 1 to 3 as shown, which shows the specific structure of the preferred embodiment of the present utility model, including a base 10, a tube shrinking seat 20, a driving mechanism 30, a first tube shrinking head 40 and a second tube shrinking head 50.

[0030] The tube shrinking seat 20 is arranged on the base 10 so as to be able to move back and forth horizontally. The outer end face of the tube shrinking seat 20 is recessed inward to form a first tube shrinking hole 201; in this embodiment, two mounting plates 11 are symmetrically arranged front and back on the base 10, and a horizontally extending slide groove 101 is formed between the two mounting plates 11; the tube shrinking seat 20 is matched with the slide groove 101 and slides back and forth along the extending direction of the slide groove 101, and the slide groove 101 is used for limiting the sliding process of the tube shrinking seat 20. The inner side walls of the two mounting plates 11 are both provided with horizontally extending slide rails 12, and the front and back side walls of the tube shrinking seat 20 are respectively provided with slide blocks 21 matched with the slide rails 12. The tube shrinking seat 20 moves back and forth horizontally along the slide rails 12 through the cooperation of the slide blocks 21 and the slide rails 12. Through the cooperation of the slide blocks 21 and the slide rails 12, the sliding process of the tube shrinking seat 20 is more stable, thus ensuring the stability of the tube shrinking process and better tube shrinking effect. A plurality of equally angularly arranged first fixing holes 202 are formed in the outer end face of the tube shrinking seat 20.

[0031] The driving mechanism 30 is arranged on the base 10 and drives the pipe shrinking seat 20 to move back and forth. In this embodiment, the driving mechanism 30 is an oil cylinder.

[0032] The first pipe shrinking head 40 is detachably arranged at the outer end of the pipe shrinking seat 20. A second pipe shrinking hole 401 corresponding to the first pipe shrinking hole 201 penetrates through the first pipe shrinking head 40, and the diameter of the second pipe shrinking hole 401 is smaller than that of the first pipe shrinking hole 201. In this embodiment, the first pipe shrinking head 40 includes a main body portion 41 and a fixing portion 42 integrally extending outward from one end of the main body portion 41 facing the pipe shrinking seat 20. A first fixing bolt 43 is arranged on the fixing portion 42. The first pipe shrinking head 40 is detachably arranged on the pipe shrinking seat 20 through the cooperation of the first fixing bolt 43 and the first fixing hole 202. In other embodiments, the first pipe shrinking head 40 can also be fixed on the pipe shrinking seat 20 by clamping, making the disassembly and assembly method of the first pipe shrinking head 40 more convenient. A second fixing hole 402 is formed at the outer end of the first pipe shrinking head 40.

[0033] The second pipe shrinking head 50 is detachably arranged at the outer end of the first pipe shrinking head 40. A third pipe shrinking hole 501 corresponding to the second pipe shrinking hole 401 penetrates through the second pipe shrinking head 50, and the diameter of the third pipe shrinking hole 501 is smaller than that of the second pipe shrinking hole 401, so that different sizes of the first pipe shrinking hole 201, the second pipe shrinking hole 401, and the third pipe shrinking hole 501 can be selected for pipe shrinking processing according to different product sizes, and the processing of more size products can be satisfied. In this embodiment, a third fixing hole 502 cooperating with the second fixing hole 402 is formed on the second pipe shrinking head 50. A second fixing bolt (not shown in the figure) sequentially passes through the third fixing hole 502 and the second fixing hole 402 to detachably arrange the second pipe shrinking head 50 at the outer end of the first pipe shrinking head 40. A guiding surface 51 is arranged at the outer end opening of the third pipe shrinking hole 501. The guiding hole 51 is used to facilitate the pipe shrinking process of small-size pipe shrinking and the docking process between the round pipe and the third pipe shrinking hole 501.

[0034] The design focus of the present utility model lies in that: a first pipe shrinking hole is formed by concavely setting inward from the outer end face of the pipe shrinking seat, and a first pipe shrinking head is detachably arranged at the outer end of the pipe shrinking seat. A second pipe shrinking hole corresponding to the first pipe shrinking hole penetrates through the first pipe shrinking head, and the diameter of the second pipe shrinking hole is smaller than that of the first pipe shrinking hole; and a second pipe shrinking head is detachably arranged at the outer end of the first pipe shrinking head. A third pipe shrinking hole corresponding to the second pipe shrinking hole penetrates through the second pipe shrinking head, and the diameter of the third pipe shrinking hole is smaller than that of the second pipe shrinking hole; so that through the first pipe shrinking hole, the second pipe shrinking hole and the third pipe shrinking hole with different diameters, when dealing with products of different diameters, it can be achieved by disassembling and assembling the first pipe shrinking head and the second pipe shrinking head, thus meeting the processing of more size products, having less use limitations, and at the same time not needing to design multiple pipe shrinking machines, effectively reducing the processing cost.

[0035] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiment according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
