Description

Flanging and flaring tool

Technical Field

The utility model belongs to the technical field of machinery, a turn-ups flaring instrument is related to, especially, relate to an instrument that can carry out the turn-ups flaring to pipeline end.

Background

The pipeline can be used for carrying out gaseous state or liquid medium's transport, and when in actual use, in order to realize the connection between the pipeline and satisfy the leakproofness requirement after connecting, often need carry out the processing of outside turn-ups to the terminal surface of pipeline, and this turn-ups can use with loop formula flange or nut cooperation. The existing pipeline flanging is generally processed and finished by corresponding large-scale processing equipment in a factory building, and then the flanged pipeline is sold for use. However, the lengths of pipes used are completely different depending on actual use places, and it is difficult to adapt the flanged pipes to various pipe use environments.

Therefore, the applicant designs a pipeline flaring and flanging tool and applies Chinese patent (the application number is 201811114970.9; the publication number is CN109013944A), the pipeline flaring and flanging tool comprises a driving tool, a clamp, a first connecting rod, a second connecting rod and a limiting piece, wherein the first connecting rod and the second connecting rod are connected with the driving tool, the limiting piece can move relative to the first connecting rod, the clamp comprises a fastener, a first clamping piece and a second clamping piece which are arranged oppositely, the first clamping piece and the second clamping piece can be buckled on the outer sides of the first connecting rod and the second connecting rod through the fastener, and the clamp can move back and forth along the axial direction of the first connecting rod and can be limited through the limiting piece after moving. When the pipe flaring and flanging tool is used, a pipe fitting is arranged between a first clamping piece and a second clamping piece, the pipe fitting is fixed by screwing a fastener, and then the end part of the pipe fitting is extruded by driving an extrusion head through a driving tool driven by hydraulic pressure so as to form the pipe flaring and flanging tool. Because the whole pipeline flaring flanging tool only comprises structures such as a driving tool and a clamp, the whole volume is small, the carrying is convenient, the flaring flanging operation can be conveniently carried out on the use site of the pipe fitting, the use in various pipe fitting use environments can be met, and the use is convenient.

However, when the pipe flaring flanging tool is actually used, the fastening piece needs to be continuously screwed or loosened to open and close the clamp to fix and loosen the pipe fitting, and the position of the clamp needs to be adjusted by adjusting the position of the limiting piece when necessary, so that the operation is complex and the use is inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem that prior art exists, provide a turn-ups flaring instrument, the technical problem that solve how to provide one kind can conveniently carry out the turn-ups flaring instrument of pipeline turn-ups flaring processing at the scene.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a turn-ups flaring instrument, includes the main part, it is first to have in the main part the shaping that is the column, the first outside of shaping has profile one, its characterized in that, turn-ups flaring instrument still establishes including the cover the stop collar that is the tube-shape in the first outside of shaping, form between stop collar and the first shaping and supply pipe fitting male one-tenth die cavity, the stop collar with still be equipped with between the main part and carry out the location structure of fixing a position to between the two.

When the flanging flaring tool is used for production, the size of the first forming head is matched with the size of an inner hole of a pipe fitting to be processed, so that the pipe fitting is just sleeved on the outer side of the first forming head. During the use, establish the stop collar cover in the outside of shaping first to through location structure with the stop collar location in the main part, make and form stable shaping chamber between stop collar and the shaping first, stretch into the shaping intracavity and support and lean on the shaping face one with the front end of pipe fitting again. And then knocking the rear end of the pipe fitting for many times to enable the front end of the pipe fitting to deform outwards along the extending direction of the forming surface I gradually until the turned edge abuts against the side wall of the limiting sleeve, so that the pipe fitting can be pulled out from the forming cavity after machining is finished. Then the pipe fitting is turned over, and the rear end of the pipe fitting is turned over and flared in the same way. In the process of this processing, need not the independent operation with the centre gripping pipe fitting, reduced operation, made things convenient for the processing operation, and strike the turn-ups flaring processing that can realize the pipe fitting through simple several times, not only convenient operation, and the shaping is comparatively rapid, and comes to carry on spacingly to the turn-ups position of pipe fitting tip through the stop collar, can guarantee stable shaping effect, need not the dynamics that the special control struck, further improved the convenience of pipe fitting processing.

In the above flanging flaring tool, the positioning structure comprises a boss protruding out of the main body and forming an annular shape and a groove recessed into the stop collar and forming an annular shape, and the boss can be correspondingly clamped into the groove.
