Abstract
The utility model provides a pre-shunt and wedge press combined male mold of a hollow blank, which is assembled and formed by adopting a pre-shunt mold, a wedge press mode and a male mold mandrel. By means of the pre-shunt mold, predistribution of metal plastic flow volume is firstly realized, so that forge piece allowance is decreased, and the material utilization ratio is increased; the wedge press mold forces metal to perform plastic flowing under the action of wedge pressure, thus, the metal plastic flow process is increased, the influence of machining to a mechanical property of a formed component is eliminated, and the purpose of improving the mechanical property of the formed component is achieved; and the male mold mandrel and a female mold form a closed cavity, so that deformed metal is restrained from further radial flowing, the contact area of the male mold and the deformed metal is decreased, and the extrusion forming force is reduced.
Description
Technical field
The utility model relates to shunt in advance-wedge of a kind of hollow blank and presses combined heave die, is applicable to hollow blank precise extrusion molding disk product, belongs to field of machining and machinebuilding technology.
Background technology
Extrusion forming process has the shape of changing modified function, is one of important forming technology of hardware manufacture.The structure of extruding punch directly determines size and shaping energy consumption, extrusion forming quality and mechanical property, the extrusion allowance of force in extrusion and shapes efficiency, so the shaping dies of Labor-saving high-efficiency is the target that the art research and designer pursue always.
Fig. 1 and the structural representation that Figure 2 shows that disk product.In prior art, adopt solid bar jumping-up, forge to squeeze and follow-up large surplus machine cut is processed three passages and is shaped, forming process is shown in schematic diagram 3, that is: first solid bar is upset as to cake, adopt on this basis the flat punch upsetting squeeze cake blank large surplus forging stock material that is shaped, finally by machine cut, shape disk product.While adopting flat punch upsetting squeeze, punch and cake blank contact area are large, and plastic force is larger, and equipment tonnage is had relatively high expectations, energy consumption is large; The allowance of the disk product of upsetting extrusion is large, and the machining cycle is long, and stock utilization is low, and machining of higher while of manufacturing cost is destroyed the mechanical property that upsetting squeeze metal streamline affects product.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, shunt in advance-wedge is pressed combined heave die structure to have proposed hollow blank, it is mainly comprised of pre-divergent die, wedge pressing mold, punch mandrel and template, wherein template is cylinder or cuboid, it is characterized in that: punch mandrel is comprised of two different cylinder one of diameter, and wherein the diameter of small-diameter circular cylinder is identical with the aperture of extrusion molding disk product; Wedge pressing mold is in the outside of punch mandrel, it is that an end face is plane, the other end hollow circular cylinder consistent with the surface configuration of extrusion molding disk product, the step-like through hole that its hollow space is total to central axis, coordinates with punch insert shaft clearance with cylinder, and the diameter of the large diameter cylinder of the corresponding punch mandrel in the aperture of planar side, planar side also offer at least 4 with the fixing bolt hole of use of template; Pre-divergent die is in the outside of wedge pressing mold, it is also that an end face is plane, the other end hollow circular cylinder consistent with the surface configuration of extrusion molding disk product, its hollow space and cylinder altogether central axis, with the through hole of wedge pressing mold matched in clearance, planar side also offer at least 4 with the fixing bolt hole of use of template, the diameter of the through hole of described pre-divergent die is less than or equal to the internal diameter of hollow blank, and the external diameter of described pre-divergent die is slightly larger than the external diameter of extrusion molding disk product;
First punch mandrel is passed so that punch mandrel and wedge pressing mold matched in clearance from the step-like through hole of wedge pressing mold, simultaneously the small-diameter circular cylinder of punch mandrel protrudes from outside the bottom surface of wedge pressing mold and is enough to form closed die cavity with corresponding die, by bolt, wedge pressing mold is fixed in template subsequently; Subsequently pre-divergent die is enclosed within to wedge pressing mold outer so that pre-divergent die and wedge pressing mold matched in clearance are fixed on pre-divergent die in template by bolt subsequently, finally to form hollow blank, shunt in advance-wedge is pressed combined heave die structure.
Compared with prior art, the utlity model has following characteristics:
1) the hollow disc product that hollow blank is shaped, the allowance of minimizing centre bore, reduces plastic force, reduces manufacturing cost.
2) pre-divergent die is realized the predistribution of plastic deformation flow volume, reduces forging surplus, improves stock utilization;
3) wedge pressing mold is realized metal Plastic Flow under wedge shape pressure-acting, increases the mobile flow process of plastic deformation, improves shaping product mechanical property;
4) punch insert axial ratio forms closed die cavity prior to die, thereby retrains the further Radial Flow of metal, has reduced the contact area of punch and deformable metal, has reduced force in extrusion.
5) assembling die is simple in structure, is convenient to change, applied widely, practical.
