The bottom connection of screw rod.
Especially, stopper slot is offered at the top of the Shaping Module, the stopper slot inner sleeve has for Shaping Module
Spacing spacing collar.
The beneficial effects of the utility model are, compared with prior art the shaping mould for short thin-walled tubes part
Using mandrel and the expansion reshaping device of Shaping Module composition, it is not only simple in structure, it is easy to accomplish；And shaping efficiency high, zero
Part shaping effect is good.
Brief description of the drawings
Fig. 1 is the solid for the shaping mould for short thin-walled tubes part that the utility model embodiment 1 provides
Fig. 2 is the assembling for the shaping mould for short thin-walled tubes part that the utility model embodiment 1 provides
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1 and Fig. 2, in the present embodiment, a kind of shaping mould for short thin-walled tubes part includes core
Axle 1 and sizing die 2, the vertical arrangement of the sizing die 2 and mandrel 1, the mandrel 1 are driven by hydraulic jack 3, the hydraulic pressure
Oil cylinder 3 drives mandrel 1 to move up and down, and the sizing die 2 is expandable to be arranged at outside mandrel 1, cylinder in the entirety of sizing die 2
Body structure, including the Shaping Module 4 of several circular arcs, the Shaping Module 4 is arranged in mounting seat 5 radially movablely,
The mandrel 1 uses up big and down small wedge-shaped axle, and the mandrel 1 uses hollow structure, and the center is equipped with screw rod 6, described
The bottom of screw rod 6 is connected through the mounting seat 5 with the piston rod of hydraulic jack 3 by helicitic texture.
Some chutes 7 are offered on the mandrel 1, the corresponding chute 7 is in fixed on the inwall of the Shaping Module 4
Have sliding block 8, the Shaping Module 4 is movably arranged at by sliding block 8 in the chute 7 of the mandrel 1, and the sliding block 8 with
Mating surface in the chute 7 is inclined-plane.
The top of the Shaping Module 4 offers stopper slot, and the stopper slot inner sleeve has for spacing to Shaping Module 4
Spacing collar 9.
During work, part will be inserted by hand outside sizing die 2, then hydraulic jack 3 drives, by screw rod 3 with moving mandrel 1
Move down, so as to finally drive each Shaping Module 4 to be radially expanded by the cooperation of sliding block 8 and chute 7, part is carried out whole
Above example simply elaborates general principle and characteristic of the present utility model, and the utility model is not by above-mentioned example
Limitation, on the premise of the spirit and scope of the utility model is not departed from, the utility model also has various change and change, these changes
Change and change and both fall within claimed the scope of the utility model.The utility model requires protection scope will by appended right
Ask book and its equivalent thereof.
