Description
Technical field
It the utility model is related to a kind of winding pipe enlarging welding auxiliary fixing device.
Background technology
The winding pipe produced at present is straight tube, needs to weld a horn-like enlarging in tubing one end after straight tube is offline
Pipe fitting, it is necessary to which flared pipe fitting is enclosed on winding pipe before welding, and tubing end is blocked by the bulge loop structure of flared pipe fitting inwall
Wall, during welding, tubing and flared pipe fitting are placed on jig, rotation on one side, heating, welded while extruding welding rod
Connect.Because the internal diameter of flared pipe fitting is big 5-10mm typically than supporting pipe internal diameter, pipe fitting is loosened, it is necessary to adopt very much after putting tubing
It is fixed with special device, its relative position is not changed in welding process, this has to final welding effect
Very big influence.
Fixed form is to make a set of baroque umbrella frame shape support at present, and umbrella frame shape branch first is placed on into pipe during welding
In material, advanced using screw thread and strut umbrella stand, first fix support and pipe material inner wall, then device fixing pipe is set on support
Part.Because umbrella frame shape supporting structure is more complicated, and certain intensity is needed, therefore heavier-weight, in welding heavy caliber pipe
When one man operation's inconvenience, and fixed form is cumbersome, takes longer, causes welding production efficiency low.
Utility model content
In order to solve the above problems, the utility model proposes a kind of winding pipe enlarging to weld auxiliary fixing device, can be quick
Easy flared pipe fitting and tubing are fixed, and are easy to weld.
What the technical solution of the utility model was realized in：
Auxiliary fixing device is welded in a kind of winding pipe enlarging, including preceding mounting flange piece 1, rear mounting flange piece 6, plug 2,
Flexible steel cable 3 and screw rod 4, the preceding mounting flange piece 1 be placed in flared pipe fitting 7 be open in and fitting the inwall of flared pipe fitting 7 it is convex
Ring structure；Described one end of flexible steel cable 3 is fixed on one end of plug 2, and the other end is fixed on one end of screw rod 4, and flexible steel cable 3
Between preceding mounting flange piece 1, rear mounting flange piece 6；The external diameter of the plug 2 is more than the preceding center of mounting flange piece 1
The aperture for the first perforate being provided with, the rear center of mounting flange piece 6, which is provided with, opens female second perforate, spiral shell
Bar 4 coincide the second perforate internal thread and pass through the second perforate, the screw rod 4 is fixed on rear mounting flange by fixing nut 5
On piece 6.
Preferably, the rear external diameter of mounting flange piece 6 is more than the internal diameter with winding pipe 8 so that the end of winding pipe 8 stops
Mounting flange piece 6 after firmly.
Preferably, the length of the flexible steel cable 3 will can guarantee that：After flexible steel cable 3 passes through winding pipe 8, in fixed spiral shell
Mother 5 can tighten when locking and hold preceding mounting flange piece 1 and rear mounting flange piece 6.
Had the beneficial effect that caused by the utility model：The utility model is connected between two flange plates using a flexible steel cable
Connect, one end welding plug of steel wire rope, the other end has the screw rod of one section of appropriate length, by tightening up screw thread in tubing afterbody to draw
Tight two pieces of flange plates, winding pipe is fastened the purpose being connected with pipe fitting so as to play, be easy to weld in next step.
