Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
Preferred embodiment 1
Present embodiments provide a kind of torch neck, as depicted in figs. 1 and 2, including nozzle body 1, nozzle
Body 1 is tubular structure, and front end is pyramidal structure, and the ring wall of nozzle body 1 is provided with bosh,
Cooling water directly or indirectly it is passed through to cool down nozzle body 1 on bosh.
The ring wall of the nozzle body 1 of the torch neck of the present embodiment is provided with the cooling water for being passed through cooling water
Groove, cooling structure is simple, and cooling water directly flows on nozzle body 1 ring wall, good cooling results.
The structure of bosh and be passed through the mode of cooling water and do not limit, is passed into cold as long as can realize cooling water
But in tank.Preferably, in the present embodiment, the structure of bosh has two kinds, specific as follows:
The first: bosh is the helical opening groove 2 being opened in nozzle body 1 outer wall, helical opening
Groove 2 is embedded with cooling water pipe 3, and cooling water pipe 3 one pipe end is intake, another pipe end water outlet.Bosh is spiral shell
The outer wall of rotation shape coiling nozzle body 1, makes cooling water pipe 3 can be coated with nozzle body 1, film-cooled heat is big,
Good cooling results.
In order to prevent cooling water pipe 3 from departing from helical opening groove 2, make the width of the opening part of helical opening groove 2
Degree is not more than the Breadth Maximum of cell body, concrete, and the cross sectional shape of helical opening groove 2 is 3/4 circle or U
Type.Further, cooling water pipe 3 is bonding or is welded in helical opening groove 2.
Owing to the temperature of nozzle body 1 front end is higher than the temperature of nozzle body 1 rear end, therefore, make near spray
The pipe end of the cooling water pipe 3 of mouth body 1 front end enters to cool down water (during water inlet, cooling water temperature is relatively low), close
The pipe end of the cooling water pipe 3 of nozzle body 1 rear end go out to cool down water (through front end cool down after, cooling water temperature liter
High).
The second: bosh is the annular water chamber 4 being arranged on nozzle body 1 ring wall, annular water chamber 4 with
Cooling water inlet 5 is connected with coolant outlet 6, and cooling water inlet 5 and coolant outlet 6 are arranged at
The rear end of nozzle body 1.Cooling water enters in annular water chamber 4 from cooling water inlet 5, from coolant outlet 6
Flow out.
The bosh of the present embodiment can also include above two structure simultaneously, i.e. as it is shown in figure 1, cold
But tank includes the helical opening groove 2 being opened in nozzle body 1 outer wall and is arranged on nozzle body 1 ring wall
On annular water chamber 4, the embedded cooling water pipe of helical opening groove 23, in annular water chamber 4 and cooling water pipe 3
It is passed through cooling water.
Preferred embodiment 2
Present embodiment discloses a kind of water cooled welding torch, as it is shown on figure 3, include owning in preferred embodiment 1
The torch neck of form, torch neck is fixed on torch body 7 front end by fixing nut 8.The present embodiment
Welding gun use above-mentioned torch neck, owing to torch neck can realize good cooling, when making the use of welding gun
Between longer, welding effect is more preferable.
Know-why of the present utility model is described above in association with specific embodiment.These describe and are intended merely to solve
Release principle of the present utility model, and the limit to this utility model protection domain can not be construed to by any way
System.Based on explanation herein, those skilled in the art need not pay performing creative labour and can associate
Other detailed description of the invention of the present utility model, these modes fall within protection domain of the present utility model it
In.
