Abstract
The utility model discloses a final-forming forging die for a fan-shaped forged piece. The final-forming forging die comprises a convex die (2) and a concave die (4). A convex die sleeve (3) is arranged outside the convex die (2), a pre-stress ring (5) is arranged outside the concave die (4), the convex die (2) stretches into an inner cavity of the concave die, a piece jacking device (7) is arranged inside the inner cavity of the concave die, and the lower end of the convex die, the upper end of the piece jacking device and the inner cavity of the concave die form a flowing space of blanks. The pre-formed blanks are placed inside the final-forming die to form a peripheral flange and a central hole of a fan-shaped worm gear final-formed blank piece. Products forged through the forging die have the advantages of being high in density, standard, neat and attractive in appearance, free of flashing and burr, low in working allowance, material-saving and beneficial to machining.
Description
Technical field
The utility model relates to accurate warm forging technical field, is specifically related to one of part worm sector in the high-voltage switch gear operating mechanism mould when forging.
Background technology
At present the manufacture method of industry interior wing die forging spare is cumbersome: a kind of technology is with bar jumping-up preformed twice, and the middle blank of recycling open die forging, impressing forging after with preformed carries out finish-forging; Another kind of technology is to utilize open die forging with the blank blocking bar, and the middle blank after utilizing open die forging, impressing forging with preformed after the forging carries out finish-forging.These two kinds of technical process are loaded down with trivial details, and forging precision is poor, and burr is big and the material consumption is high.
The high-voltage switch gear operating mechanism of using in China's high voltage power transmission and transforming industry, because of the design of part change of shape in its operating mechanism of each side reason bigger, the manufacturing process difficulty is big, and serviceability difference is also very big, the related variation of used control components and parts to the operating mechanism.Wherein to the worm gear of one of control device of the invention, the strict fixedly rotation use angle that requires.The domestic worm gear that is used in the high-voltage switch gear operating mechanism generally is unitary circular (as shown in Figure 1) at present, and high-voltage switch gear is no more than 180 ° because of the real strict fixedly anglec of rotation of each side reason worm gear in operating mechanism, round operation is all like this, be that another of unitary circular worm gear is with idle running mostly, do not participate in essence engagement operations control work.Owing to worm gear copper alloy (aluminium bronze) material manufacturing, this coppr alloy-metal is in precious metal material again, and the market price is higher.
To sum up, have the worm gear forging structure in the high-voltage switch gear product, used now and existing fan-shaped forging manufacturing process is unreasonable.
Summary of the invention
The invention technical problem to be solved provides the closed mould finish forge mould of the complicated worm sector of a kind of forging.
For achieving the above object, following technical scheme is adopted in the invention:
A kind of final shaping unit forging mold of fan-shaped forging comprises punch, die, and described punch arranges punch case outward; Described die arranges shrink ring outward; Punch stretches into the die inner chamber, and ejector is arranged in the die inner chamber, and punch lower end, ejector upper end and die inner chamber form the flowing space of blank.
Further, on the described punch pressing plate is set.
Further, described shrink ring arranges pressing plate outward.
The preformed blank places the final shaping unit mould to form outer ring bead and the centre bore of worm sector final shaping unit blank.
Owing to adopted technique scheme, the invention to have following beneficial effect:
The product that this forging mold forges has the material density height, and neat appearance is attractive in appearance not to have burr, and allowance is little, and not only material-saving also is beneficial to mach advantage.
Description of drawings
Fig. 1 is the structural representation of existing unitary circular worm gear;
Fig. 2 is the structural representation of 120 ° of worm sectors of the invention low-angle;
Fig. 3 is the structural representation of 135 ° of worm sectors of the invention wide-angle;
Fig. 4 is the structural representation of the whole shaping forging mold of the invention.
The specific embodiment
As Fig. 4, the final shaping unit mould of fan-shaped forging comprises punch 2, die 4, and described punch arranges punch case 3 outward, and the punch upper end arranges pressing plate 1; Described die 4 outer shrink ring 5, the pressing plates 6 of setting gradually; Punch stretches into the die inner chamber, and ejector 7 is arranged in the die inner chamber, and punch lower end, ejector upper end and die inner chamber form the flowing space of preformed blank.
As Fig. 4, in conjunction with Fig. 2 and Fig. 3, the preformed blank places the final shaping unit mould, blank the die inner chamber to around flow deformation, being full of mold cavity forming is outer ring bead and the centre bore of worm sector final shaping unit blank.
Wherein, before and after the forging that is shaped eventually, all should spray lubricant to die cavity, behind product of every forging all to die cavity carry out pressure-air cleaning and lubricated once, concrete grammar is: with the two-tube air blowing spray gun of pressure-air, first time first Air blowing cleaning die cavity, second time lower mode cavity spraying skim water-based graphite breast lubricant up.Lubricant has alleviated the friction of blank and mould, makes blank Plastic Forming smoothness, and product shape is full attractive in appearance, has prolonged the service life of mould simultaneously.
As Fig. 2 and Fig. 3, the low-angle worm sector that the wide-angle worm sector that segment angle after being shaped eventually is 135 ° and segment angle are 120 °, again through machined bore, rough turn, finish turning, boring, hinge, gear hobbing, deburring etc., according to the inspection eventually of size among the figure separately, make geometry and engineering size satisfy the design drawing requirement.
The worm sector that the invention mould forges is because by the operating angle scope that is suitable for, can satisfy reliably and come and go the motion action requirement, can reduce material consumption and production cost in a large number again, distribute and use target rationally thereby worm gear in this grade high-voltage switch gear operating mechanism is reached.
Claims (3)
