Abstract
The utility model provides a precision forging mould for a floating straight-tooth cylindrical gear, which adopts the structure of a floating concave mould capable of moving up and down on the basis of the structure of a common precision forging mould rack. The floating concave mould provides guiding and positioning by a guide post of the mould rack, and provides an elastic jacking force required for restoration by a rectangular spring. When in precision forging, a blank is put into the floating concave mould, a pressure machine sliding block drives an upper mould to descend; after an upper mould is in contact with the blank, the blank starts to be deformed; the upper mould is in contact with the floating concave mould after moving downwards for certain stroke; at the moment, the upper mould, the lower mould and the floating concave mould combine an enclosed cavity; the continuous descending of the upper mould can push the floating concave mould to move downwards at the same time as compressing the rectangular spring, so as to lead the floating concave mould to generate relative motion with the blank, and lead metal to easily fill the corner position of the tooth-shaped cavity, thereby effectively reducing the forming load, prolonging the service life of the mould, simplifying the mould structure, and reducing the manufacturing cost.
Description
Technical field
The utility model relates to a kind of precision form mould, and especially a kind of floating type straight spur gear finish forge mould belongs to stress metal processing mold field.
Background technology
Straight spur gear is to use important very widely driving parts in industries such as automobile, the energy, machinery, has simple in structurely, can realize characteristics such as high pulling torque and high efficiency transmission, good reliability.In modern industry is produced,, generally adopt forging to make in conjunction with mechanical processing tools for improving its mechanical performance and stock utilization.Because the finish forge straight spur gear has the characteristics of profile of tooth die cavity corner place's filling difficulty, the application of closed stamping hydraulic mould frame at present successfully addresses this problem and has realized the finish forge production of straight spur gear, but the closed stamping hydraulic mould frame cost is higher, and still need bigger plastic force to make metal be full of die cavity, thereby cause the increase of service load, the finish forge core rod life-span reduces, and production cost increases.
Summary of the invention
For overcome existing finish forge straight spur gear produce in service load big, the deficiency that die life is low, it is a kind of simple in structure that the utility model provides, die manufacturing cost is low, can effectively improve the floating type straight spur gear finish forge mould in core rod life-span.
The technical scheme that the utility model adopted is: on the basis of common precision forging die shelf structure, the floating cavity die structure that employing can move up and down, described floating cavity die is that the guide pillar by mould bases provides guiding and location, provides the bullet top that resets required power by the rectangle spring.During finish forge blank is put into floating cavity die, it is descending that press ram drives patrix, patrix contacts the back blank and begins to produce distortion with blank, patrix contacts with floating cavity die after moving downward certain stroke, this moment patrix, counterdie and floating cavity die are formed the die cavity of sealing together, guild's promotion floating cavity die in compression rectangle spring moves downward together under the continuation of patrix, make floating cavity die and blank produce relative motion, frictional force between the core rod inner surface that this relative motion produces and the blank outer surface is identical with the flow direction of metal material, be of value to flowing of metal material, can be so that metal be easier to fill profile of tooth die cavity corner place, thereby effectively reduce shaping load, improve die life.
The beneficial effects of the utility model are, the shaping load of finish forge straight spur gear is reduced, and improve die life, compare with adopting closed stamping hydraulic mould frame finish forge straight spur gear, have simplified mould structure, have reduced manufacturing cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model mould structure schematic diagram.
Among the figure, 1. cope match-plate pattern, 2. guide pillar, 3. upper die plate, 4. patrix, 5. upper mould fixed plate, 6. upper molded plate, 7. die core rod, 8. circle stress, 9. floating cavity die, 10. caging bolt, 11. rectangle springs, 12. the counterdie backing plate, 13. counterdies, 14. push rods, 15. lower bolsters, 16. blanks.
The specific embodiment
In the embodiment shown in the figures, patrix (4) is pressed on the upper die plate (3) by upper mould fixed plate (5) and upper molded plate (6), and be fixed on the cope match-plate pattern (1), die core rod (7) and circle stress (8) are fixed on the floating cavity die (9), the rectangle spring (11) that several caging bolts (10) pass floating cavity die (9) and equal number is fixed on the lower bolster (15), floating cavity die (9) is provided support by rectangle spring (11), the centering of guiding and assurance die core rod (7) and patrix (4) is provided by guide pillar (2), the bottom surface of counterdie (13) places on the counterdie backing plate (12), the upper end is stretched in the die core rod (7), and push rod (14) places counterdie backing plate (12) and lower bolster (15).
During finish forge, blank (16) is put into die core rod (7), it is descending that press ram drives patrix (4), patrix (4) is with after blank (16) contacts, blank (16) begins to produce plastic deformation, patrix (4) contacts with floating cavity die (9) after moving downward certain stroke, patrix this moment (4) is formed the die cavity that seals with counterdie (13) and floating cavity die (9), guild's promotion floating cavity die (9) moves downward in compression rectangle spring (11) under the continuation of patrix (4), make floating cavity die (9) and blank (16) produce relative motion, die core rod (7) inner surface and the frictional force between blank (16) outer surface that this relative motion produces can be so that metal be easier to fill profile of tooth die cavity corner place.After shaping is finished, press ram drives patrix (4) backhaul, and rectangle spring (11) by compression promotes floating cavity die (9) and resets, and ejecting mechanism promotes push rod (14) under the forcing press, push rod (14) promotes counterdie (13), and the workpiece after being shaped is ejected die core rod (7).
Claims (3)
1. floating type straight spur gear finish forge mould is characterized in that: on the basis of common precision forging die shelf structure, and the floating cavity die structure that employing can move up and down.
2. floating type straight spur gear finish forge mould as claimed in claim 1 is characterized in that: described floating cavity die provides guiding and location by the mould bases guide pillar.
