Description
Technical field
The utility model is related to a kind of threeway to make field, and a kind of especially flange threeway for boiler industry makes dress
Put.
Background technology
Current threeway manufacturing process is a lot, such as suppresses threeway, forging and stamping threeway, hydraulic pressure threeway, welding tee, and in boiler
In industry, because operating mode is special, threeway is needed to be worked under high temperature, hyperbaric environment, and boiler industry threeway is made generally using pipe
Base hot press forming method.Threeway hot forming is the pipe that will be greater than threeway diameter, is flattened about to the size of threeway diameter, pipe
It is heated, it is put into finishing die, and load the punch die of stretching branch pipe in pipe, pipe is radially pressed under the effect of the pressure
Contracting, metal flows to branch pipe direction and forms branch pipe under the stretching of punch die during radial compression, and whole process is logical
Cross the radial compression of pipe and the drawing process at branch pipe position and shape.Threeway deflection is made under this kind of method big, it is processed
Journey needs to be extruded step by step using many molds to complete, and extrusion process needs heating for multiple times and more mold exchange, when increased making
Between, the energy, mould and artificial consuming are big, low production efficiency；Required pipe diameter is approximately more than 1.5 times of product threeway diameter,
Cause the waste of the energy and resource.
Utility model content
The utility model provides a kind of flange threeway producing device to solve above-mentioned technical problem.
The technical scheme that the utility model is used is：Flange threeway producing device, including upper mould and placement blank workpiece
Lower mould, lower mould connecting working table, workbench is placed in pull-down device top, also including pull bar and the core that is placed in workpiece, institute
State lower mould and the one side of workbench is provided with lower nib, pull bar can the upper and lower motion in lower nib, simple structure, operation letter
Just, reduce production cost, improve production efficiency.
Connected using spline structure between pull bar and pull-down device, be capable of achieving quickly to be installed between pull bar and pull-down device
And dismounting, it is time saving and energy saving.
For steady brace and core, the one end on pull bar near core is provided with pin-and-hole.
For the threeway inwall for reducing the frictional force between core and workpiece and make is more smooth, core is bowl-shape.
To enable pull bar to drive core to move downward through core, core is provided centrally with the core that pull bar can be allowed to pass through
Hole.
Lifting is more convenient during for dismounting pull bar, and pull bar side is provided with two symmetrical anchor ears.
To avoid oxide skin from falling into pull bar and pull-down device junction, anchor ear lower section is provided with dust-proof cushion.
For fixed and accurate installation be provided with location hole below pull bar and pull-down device, dust-proof cushion.
The beneficial effects of the utility model are：The utility model pull bar is connected with pull-down device using spline structure, can be real
It is existing quickly to be mounted and dismounted between pull bar and pull-down device, it is time saving and energy saving；Pull-down device cylinder lever connecting rod drives core to transport downwards
It is dynamic to make threeway, whole process one-shot forming, simple structure, operation are easy, reduce production cost, improve production efficiency.

Specific embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and Figure 3, the utility model be a kind of flange threeway producing device, including upper mould 1 and place hair
The lower mould 2 of base workpiece 3, lower mould 2 is connected by workbench 4 with pull-down device, also including pull bar 5 and being placed in blank workpiece 3
Core 6, lower mould 2 is provided with lower nib 7 near the one side of workbench 4, and pull bar 5 can the upper and lower motion in lower nib 7；Pull bar 5 with
Connected using spline structure between pull-down device；One end on pull bar 5 near core 6 is provided with pin-and-hole 8；Core 6 is bowl-shape, core
Mould 6 is provided centrally with the core hole 9 that pull bar 5 can be allowed to pass through；The side of pull bar 5 is provided with two symmetrical anchor ears 10；Under anchor ear 10
Side is provided with dust-proof cushion 11；The lower section of dust-proof cushion 11 is provided with location hole 12.
The processed blank workpiece 3 has been preheated, and side is provided with elliptical openings, and the short axle of oval opening is long
More than the diameter of pull bar 5, pull bar 5 can the upper and lower motion at elliptical openings.
The warmed-up blank workpiece 3 for finishing is placed on lower mould 2, the opening of blank workpiece 3 is adjusted towards pull bar 5, covered
Upper mould 1, the top of upper mould 1 connection pushes equipment, fixes upper and lower mould, core 6 is placed in blank workpiece 3, makes core hole
