Abstract
The utility model relates to an inner hole bulging and reshaping mould for narrow trough rotary body, in particular to an inner hole bulging and reshaping mould for drawn punched automobile parts. The utility model discloses a reshaping concave mould capable of floating up and down on the periphery of the material return ring, a height limit block arranged between the reshaping concave groove and an upper mould plate, a polyurethane spring arranged between a material press plate and the upper mould plate. The utility model can effectively control the flowing of work piece material and avoid material from flowing on the punch mould, and protects the punch mould, prolongs the service life of mould, reduces production cost and improves the quality of punched products.
Description
Technical field
The utility model relates to a kind of auto parts diel, specifically endoporus bulging, integer mould behind a kind of pull and stretch of part punching of automobile.
Background technology
Piston retainer in the automatic gearbox of auto parts is actually a kind of narrow groove rotary body part as shown in Figure 2, to the technology of the conventional punching press of the part of this type is: 1, blanking and drawing urceolus; 2, reverse drawing inner core; 3, towards mesopore; 4, turn over endoporus; 5, shaping; 6, cut edge.Corresponding above technology, employed shaping mould is simple in structure, generally is used to make the less demanding situation of workpiece, yet material is mobile breaks punch-die owing to the punch-die top is easy to generate when shaping, influences ordinary production, production cost is raise, and product quality is relatively poor.
Summary of the invention
The utility model relates to endoporus expanding die behind a kind of narrow groove rotary body pull and stretch; it has overcome the defective of routine techniques; effectively the control workpiece material flows; can not produce material at the punch-die top flows and the protection punch-die; prolong the life-span of mould; reduce production costs, also improve the quality that stamps out product simultaneously.
Technical solution of the present utility model is at existing three moving hydraulic presses and mould structure setting, material returned ring, the bulging punch, the bulging punch-die, the integer punch, correcting die on the holding pad basis, the utility model is equipped with the integer die that can fluctuate particularly in material returned ring outer periphery, is provided with the limit for height piece between integer die and cope match-plate pattern, is provided with polyurethane spring between holding pad and cope match-plate pattern.
More than be provided with spring assembly between integer die described in the utility model and cope match-plate pattern, die can be fluctuated.
Be provided with two limit for height pieces between integer die described in the utility model and cope match-plate pattern, described limit for height piece is evenly distributed and is fixed on cope match-plate pattern.
Operation principle of the present utility model is owing to utilized three moving hydraulic presses, unsteady integer die and polyurethane spring, in bulging and trimming, workpiece material has been locked pressurized during the inner chamber bulging, plasticity improves, effective flowing of control material can not produce material at the punch-die top and flow and break punch-die.
The utility model advantage is:
1, effectively controls workpiece material and flow, can not produce material at the punch-die top and flow and the protection punch-die, prolong the life-span of mould, reduce production costs, be convenient to promote and use;
2, improve the quality that stamps out product, make the product roughness reduce.
