Problems solved by technology

However, there is a problem in the above-mentioned method 1: it greatly increases the production cost; there is also a problem in the method 2: it causes a waste of resources
However, there is still a problem with this flaring tool: the pressure source and the hydraulic pump need to be connected through a hose, which makes the whole tool relatively loose, which is not conducive to carrying and using

Embodiment 1

[0043] Such as figure 2 As shown, the shoulder forming device of the metal circular tube is composed of a bracket 5, a support member 6, a connecting member 7, an inclined block 8, a driving member 9, an elastic member 10 and the like.

[0044] Among them, such as Figure 2 to Figure 4 As shown, the bracket 5 is composed of two horizontally arranged support plates 5a and a column 5b between the two support plates 5a. The upper and lower ends of the column 5b are respectively fixed to the two support plates 5a. Wherein, the support plate 5 a located below is the bottom of the support 5 , and the support plate 5 a located above is the top of the support. In this embodiment, there are four columns 5b located around the support plate 5a.

[0045] The connecting piece 7 is in the shape of a straight rod and is slidably connected in the bracket 5 along the horizontal direction. Wherein, it is possible for the connecting piece 7 to be hollow, solid or semi-hollow and semi-solid....

Embodiment 2

[0054] The structure and principle of the second embodiment are basically the same as those of the first embodiment, except that the buffer mechanism includes extension springs whose two ends are respectively fixed to the lower end of the inclined block and the bottom wall of the bracket 5 .

Embodiment 3

[0056] The structure and principle of this third embodiment are basically the same as that of the first embodiment, except that the extruding mechanism includes a pressure ring 2 sleeved and fixed on the connecting part 7b, and the two ends of the elastic member 10 are connected to the pressure ring 2 respectively. It abuts against the end face of the support member 6.

Abstract

The invention provides a shoulder forming device of a metal circular tube, which belongs to the technical field of machinery. It solves the problem that the shoulders of the existing metal round pipes can only be processed in factories. The shoulder forming device of the metal round tube includes a straight rod-shaped connecting piece, one of the end surfaces of the connecting piece is provided with an extruding mechanism for forming the shoulder of the metal round tube by extruding the elastic piece, and the forming device also includes The bracket, the connector is slidingly connected in the bracket along the horizontal direction, the side wall of the connector is vertically penetrated with a guide hole, the guide hole is pierced with a slanting block, and the inner side wall of the guide hole is provided with a slanting block. There is an inclined surface, and there is a gap for the translation of the connecting piece between the inner side wall of the guide hole and the inclined block, and a driving member capable of driving the inclined block to translate up and down is fixed in the bracket. The shoulder forming device of the metal circular pipe has the advantage of being able to process the shoulder on site.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a shoulder forming device of a metal circular tube. Background technique [0002] Metal round pipes (or metal water pipes) are pipes for cooling, hot water, gas, or sewage, and are generally made of copper or stainless steel. In modern decoration, the metal round pipes are all installed in the buried wall construction, that is, the metal round pipes are basically located in the wall, and only a small part protrudes from the wall and is connected with other water pipes through joints to achieve the purpose of transporting water. [0003] The connection structure of existing metal round pipes and joints is as follows: figure 1 As shown, the joint 2 has a connection end 2a communicating with its inner cavity, and the connection structure includes a lock nut 3, a connection end 2a, and an annular shoulder 1a on the outside of the metal tube 1, the shoulder 1a and the connection end 2...
