Description
Technical field
The utility model relates to pipe fitting manufacturing field more particularly to three-way pipe forming devices.
Background technique
In the prior art, threeway hot forming is the pipe that will be greater than threeway diameter, flattens the size about to threeway diameter,
A hole is opened at the position for stretching branch pipe；Pipe is heated, is put into finishing die, and is packed into pipe and stretches rushing for branch pipe
Mould；Pipe is radially compressed under the effect of the pressure, and metal flows to branch pipe direction and in punch die during radial compression
Stretching under form branch pipe.Whole process is shaped by the radial compression of pipe and the drawing process at branch pipe position.With liquid
It presses unlike bulging threeway, the metal of hot-pressed three-way pipe fitting branch pipe is compensated by the radial motion of pipe, so also referred to as
Radial compensation technique.
In actual operation, due to generating biggish power in pressing process, if the bolster fixation of pressing die is bad, hold
It easily causes mold to loosen, leads to the deformation of products of compacting, usually mold is placed on workbench, then pushed by top
Mode mold compression leg is fixed, but this kind of mode is difficult to the equal fixing compact of mold transverse and longitudinal, still will appear product pressing
Not accurate problem, and having with pipe fitting is circle, if mold delocalization, easily causes rotation, causes between pipe fitting and branched pipe
Displacement is generated, causes product unqualified.
Utility model content
In order to solve the above technical problems, the utility model proposes a kind of three-way pipe forming device, including two levels are set
The hydraulic cylinder set, the hydraulic cylinder output end are equipped with positioning device, are equipped with molding die, the molding between the positioning device
Mold includes cope plate and lower template, and the cope plate and lower template are semi-cylindrical, is set between the cope plate and lower template
There is cylindricality die cavity；The lower template side wall is equipped with branched hole；Annular array on the cope plate and the sagittal plane of lower template end
There is location hole；The hydraulic cylinder output end passes through the positioning device and is directed toward the molding die.
Preferably, the positioning device includes positioning ring block, and the positioning ring block annular array is provided with positioning column, described
Positioning column is corresponding with the location hole.
Preferably, the hydraulic cylinder output end is equipped with encircling mat layer, and the encircling mat layer is made of titanium alloy.

Wherein, 1, hydraulic cylinder；2, positioning device；3, molding die；4, cope plate；5, lower template；6, branched hole；7, it positions
Hole；8, positioning ring block；9, positioning column；10, encircling mat layer；11, cylindricality die cavity.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
As shown in FIG. 1 to FIG. 2, the utility model proposes a kind of three-way pipe forming device, including two horizontally disposed
Hydraulic cylinder 1,1 output end of hydraulic cylinder are equipped with positioning device 2, are equipped with molding die 3, shaping mould between the positioning device 2
Pipe fitting is placed in molding die 3 by tool 3 between two hydraulic cylinders 1,
Specifically, the molding die 3 includes cope plate 4 and lower template 5, and the cope plate 4 and lower template 5 are semicircle
Cylindricality is equipped with cylindricality die cavity 11 between the cope plate 4 and lower template 5；5 side wall of lower template is equipped with branched hole 6；On described
Ring row shows location hole 7 on the sagittal plane of 5 end of template 4 and lower template；1 output end of hydraulic cylinder is filled across the positioning
It sets 2 and is directed toward the molding die 3, pipe fitting is placed in cylindricality die cavity 11, and the positioning device 2 at both ends passes through after positioning pipe fitting
Hydraulic cylinder applies pressure at both ends, so that pipe fitting squeezes out tee tube from 6 position of branched hole.
Specifically, the positioning device 2 includes positioning ring block 8, and 8 annular of positioning ring block is disposed with positioning
Column 9, the positioning column 9 is corresponding with the location hole 7, and when hydraulic cylinder 1 pushes, the positioning column 9 in positioning ring block 8 is inserted into positioning
In hole 7, and the location hole 7 is cuboid, and the positioning column 9 is cuboid, can position positioning ring block 8 and molding
Mold 3 prevents from being subjected to displacement between the two, and positioning ring block 8 is pressed on molding die 3, passes through the side of positioning ring block 8
Edge and positioning column 9 can prevent cope plate 4 and lower template 5 from separating, and guarantee that pipe fitting is bonded closely with cope plate 4 and lower template 5, protect
