Abstract
The invention discloses a kind of necking tool, including necking head and gripping handle, the necking head forms the first necking arm, the second necking arm, third necking arm and the 4th necking arm of a round bore between having after connection；First necking arm both ends respectively can be pivotally mutually hinged around the first pivotal axis, the second pivotal axis with the second necking arm, third necking arm one end, and the second necking arm other end can be pivotally mutually hinged around the second pivotal axis with the 4th necking arm one end；Gripping handle has first handle and second handle, and first handle one end is locked on the third necking arm other end；Second handle one end is locked on the 4th necking arm other end.The quick necking of thin-wall pipe can be achieved in the present invention, and simple in structure, easy to operate, especially cost is very cheap, and economic performance is good, is very beneficial for medium-sized and small enterprises use.
Description
Technical field
The present invention relates to a kind of necking tools, and in particular to a kind of necking tool of pipe fitting part.
Background technology
In the prior art, the spacer in pipe fitting part such as bearing type water tank, one end need to first carry out necking when installation, pass
The necking method of system carries out necking using after gas welding heating with the method that hand hammer taps, and necking surface is caused ripple, recessed easily occur
Hole, not round and smooth phenomenon influence product design beauty, and ratio of briquetting is low, and labor intensity is big, and efficiency is low.People think always for a long time
It solves the problems, such as the mechanization of necking down tubes, but fails to solve always.
Invention content
For the above technical problems, the purpose of the present invention is：It proposes a kind of of simple structure and low cost and grasps
Make convenient necking tool.
What technical solution of the invention was realized in：A kind of necking tool, including necking head and gripping handle, institute
The first necking arm, the second necking arm, the third necking arm and the 4th of a round bore are formed between stating necking head and having after connection
Necking arm；The first necking arm both ends are pivoted with the second necking arm, third necking arm one end around the first pivotal axis, second respectively
Axis can be pivotally mutually hinged, the second necking arm other end and the 4th necking arm one end around the second pivotal axis can pivotally that
This is hinged；The gripping handle has first handle and second handle, and it is another that described first handle one end is locked in third necking arm
On one end；Described second handle one end is locked on the 4th necking arm other end.
Preferably, spring is equipped between the first handle and second handle.
Due to the application of the above technical scheme, the present invention has following advantages compared with prior art：
A kind of necking tool of the present invention, when needing necking, both hands break first handle and second handle into two with one's hands, between each other can pivot
The first necking arm, the second necking arm, third necking arm and the 4th necking arm for turning mutually hinged are flared out, and will wait needing to contract
Mouth part is put into it, and both hands compress gripping handle with strength, you can realize the quick necking of thin-wall pipe, simple in structure, operation side
Just, especially cost is very cheap, and economic performance is good, is very beneficial for medium-sized and small enterprises use.
Description of the drawings
Technical scheme of the present invention is further explained below in conjunction with the accompanying drawings：
Attached drawing 1 is a kind of structural schematic diagram of necking tool of the present invention；
Wherein：1, the first necking arm；2, the second necking arm；3, third necking arm；4, the 4th necking arm；5, first handle；
6, second handle；7, the first pivotal axis；8, the second pivotal axis；9, spring.
Specific implementation mode
Illustrate the present invention below in conjunction with the accompanying drawings.
Attached drawing 1 is a kind of necking tool of the present invention, including necking head and gripping handle, and the necking head, which has, to be connected
The first necking arm 1, the second necking arm 2, third necking arm 3 and the 4th necking arm 4 of a round bore are formed between connecing afterwards；It is described
First necking arm, 1 both ends are respectively with the second necking arm 2,3 one end of third necking arm around the first pivotal axis 7,8 energy pivot of the second pivotal axis
Turn mutually hinged, 2 other end of the second necking arm and 4 one end of the 4th necking arm can pivotally each other around the second pivotal axis 8
It is hinged；The gripping handle has first handle 5 and second handle 6, and 5 one end of the first handle is locked in third necking arm 3
On the other end；6 one end of the second handle is locked on 4 other end of the 4th necking arm；The first handle 5 and second handle 6
Between be equipped with spring 9.When needing necking, both hands break first handle 5 and second handle 6 into two with one's hands, between each other can be pivotally mutually hinged
The first necking arm 1, the second necking arm 2, third necking arm 3 and the 4th necking arm 4 be flared out, necking part to be needed is put into
In it, both hands compress gripping handle with strength, you can realize the quick necking of thin-wall pipe, it is simple in structure, and it is easy to operate, especially
Cost is very cheap, and economic performance is good, is very beneficial for medium-sized and small enterprises use.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and be implemented, and it is not intended to limit the scope of the present invention, all according to the present invention
Equivalent change or modification made by Spirit Essence should all cover within the scope of the present invention.
