In the step (3), after the bowl-shape drawing part is heated to 700~900 DEG C, then carry out hot-pressed.
In the step (3), the hot extrusion casting die formation oral area is open, the centre bore of bottom lock, the centre bore
Oral area is equipped with stepped hole, and the aperture of the stepped hole is more than the aperture of the centre bore.
In the step (6), the thin slice of the finishing part bottom forms base apertures, the aperture of the base apertures by punching
Less than the aperture of the centre bore.
In the step (5), the lateral wall of the mouth flange, base flange and finishing part, which is collectively formed, accommodates belt
Annular receiving groove.
The thickness of the supplied materials steel plate is 5mm.
The present invention has the following advantages compared with prior art：
1st, the forming technology of a kind of expansion tightening wheel provided by the invention, as a result of drawing, hot extrusion, cold extrusion, finishing
The problems such as waiting plastic molding methods, overcoming big waste of material amount in the prior art, low production efficiency, poor production environment, brings
Stock utilization is high, production efficiency is high, the technique effects such as at low cost.
2nd, the forming technology of a kind of expansion tightening wheel provided by the invention, supplied materials steel plate form plate-like blank, then through drawing through blanking
Deep forming is bowl-shape drawing part, then hot-pressed to the progress of bowl-shape drawing part, and forming oral area has the mouth horizontally outward extended
Among portion's flange, bottom thin slice is formed due to being squeezed and bottom periphery forms the hot extrusion of the bulge loop extended to vertical direction
Part using the hot-pressed resistance of deformation that can effectively reduce metal, increases the Plastic Forming performance of metal, is conducive to material hair
Raw large plastometric set, improves part forming quality, and it is hot-pressed when plastic force needed for metal become smaller, to former tonnage
It is of less demanding.
Hot extrusion casting die is air-cooled to room temperature, then carries out cold-extruded by a kind of the 3rd, forming technology of expansion tightening wheel provided by the invention
Pressure, formed cold-extruded part, the purpose of cold extrusion be bottom periphery is formed squeezed to the bulge loop that vertical direction extends to be formed in it is small
Outer big horn-like flange, so as to the forming of subsequent processing part, the deformation of part can be effectively reduced using cold extrusion process
Amount reduces plastic force, and so as to improve part forming quality, and the forming for base flange is prepared.
The flange of cold-extruded part is carried out finishing, forms bottom by a kind of the 4th, forming technology of expansion tightening wheel provided by the invention
Flange obtains finishing part, using finishing procedure can valid shaping base flange, improve part forming precision.
