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 convex shoulder forming device for cylindrical metal tubes, belongs to the technical field of machinery, and solves the problem that the convex shoulder of the conventional cylindrical metal tube can only be processed in a factory. The convex shoulder forming device comprises a straight-rod-shaped connecting piece, and an extrusion mechanism which is used for forming the convex shoulder of the cylindrical metal tube through an extrusion elastic piece is arranged on one end surface of the connecting piece. The forming device further comprises a support, and the connecting piece is connected into the support in a sliding manner in the horizontal direction. A guide hole penetrating the side wall of the connecting piece in the vertical direction, and an oblique block penetrates into the guide hole. An oblique surface close to the oblique block is arranged on the inner side wall of the guide hole, and a gap for enabling the connecting piece to translate is formed between the inner side wall of the guide hole and the oblique block. A driving piece which can driving the oblique block to translate up and down is fixedly arranged in the support. The convex shoulder forming device has the advantage that the convex shoulder forming device can process the convex 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...
