Description
Technical field
The utility model relates to mould applications, specifically a kind of thin wall connecting axle warm forging, cold extrusion die.
Background technology
Thin wall connecting axle finished product wall thickness only has 3mm, and length is more than 75mm, if adopt thermal forging technology, wall thickness need to be thickeied to 8mm, can forge shaping, and very large to mould infringement, lathe overload, is difficult to realize mass production, and cold working cost increases severely.
Now adopt warm forging technique, obtain semi-finished product, then after saponification processing, adopt cold-extrusion technology to make its inner chamber shaping, finally obtain blank finished product. After adopting cold-extrusion technology, connecting axle inner chamber only needs partial operation that finished product requirement can be reached.
Utility model content
The purpose of this utility model is to provide the warm forging of a kind of thin wall connecting axle, cold extrusion die, and the ratchet being arranged on mould by elasticity carries out automatic demoulding to workpiece, realizes operation automation.
The technical solution of the utility model is as follows:
The warm forging of a kind of thin wall connecting axle, cold extrusion die, include upper and lower template and die shoe, described die shoe is fixedly mounted on lower bolster, it is characterized in that: position, die shoe top stage hole is set with ratchet pallet, the top end face of ratchet pallet is provided with concentric die, die is set with multilayer shrink ring outward, and die and multilayer shrink ring top are pressed with the gland being fixed on die shoe; Described ratchet pallet is provided with circumferentially 120 ° of six uniform square step through-holes, bolt is fitted with in square step through-hole, bolt head is positioned at outside square step through-hole, bolt shank is set with the ratchet for the demoulding, bolt shank is set with spring in position between ratchet and the step wall of square stepped hole, and ratchet head stretches out square step through-hole; The lower surface of described cope match-plate pattern is fixed with base, base is provided with the drift coordinating with die.
The warm forging of a kind of thin wall connecting axle, cold extrusion die, is characterized in that: on the lower surface of described base, be fixed with adapter sleeve, be set with contiguous block in adapter sleeve, the bottom surface of contiguous block is fixed with drift.
The warm forging of a kind of thin wall connecting axle, cold extrusion die, it is characterized in that: die is set with inside and outside two-layer shrink ring outward, the stepped hole on gland coordinates with External prestressed circle; Described gland hexagon-headed bolt is connected with die shoe.
The warm forging of a kind of thin wall connecting axle, cold extrusion die, is characterized in that: described ratchet pallet is between die and die shoe, and the upper and lower stepped hole of ratchet pallet coordinates with External prestressed circle and die shoe respectively.
The warm forging of a kind of thin wall connecting axle, cold extrusion die, is characterized in that: described ratchet head upper end is arc.
During work, workpiece is placed with in described die, described drift moves down, and extend into extruding workpiece in die, now workpiece pressurized moving down in die, when workpiece moves down into the curved end of ratchet, due to the elastic force effect of spring, ratchet keeps off at workpiece oral area, ensures that workpiece can not with moving on drift, make workpiece automatic demoulding, finally make the inner chamber of workpiece and cylindrical sidewall shaping.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, reliable, operating efficiency is high, by the preformed blank of warm forging, carry out cold extrusion final molding, the direct forge hot that solves thin wall connecting axle is difficult to shaping problem, ensure that the product quality of final molding, Product Precision is high, and cold working time shorten, saves material, and product cavity only needs partial operation, improves the service life of product.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
See Fig. 1.
The warm forging of a kind of thin wall connecting axle, cold extrusion die, include upper and lower template 1,19 and die shoe 18, die shoe 18 is fixedly mounted on lower bolster 19 by hexagon socket head cap screw 20, die 10 adopts taper fit to be press-fit in inside and outside shrink ring 11,14, gland 13 is connected with die shoe 18 with hexagon-headed bolt 12, and the stepped hole on gland 13 coordinates with External prestressed circle 14. Ratchet pallet 21 is had between die 10 and die shoe 18, the upper and lower stepped hole of pallet 21 coordinates with External prestressed circle 14 and die shoe 18 respectively, pallet 21 is provided with circumferentially 120 ° of uniform square through holes, nut is passed through in square opening, screw rod 17, spring 16 are connected with ratchet 15, can be movable in square opening, play demoulding effect, the lower surface of cope match-plate pattern 1 is installed with base 3 by hexagon socket head cap screw 2, and base 3 is fixed with towards the drift 8 of die 10 by contiguous block 4,7.
Workpiece 9 is placed with in die 10, drift 8 moves down, extend into the interior extruding workpiece 9 of die 10, now workpiece 9 pressurized moving down in die 10, when workpiece 9 moves down into the end of ratchet 15, due to the elastic force effect of spring 16, ratchet 15 keeps off at workpiece 9 oral area, ensure that workpiece 9 can not, with moving on drift 8, make workpiece 9 automatic demoulding, finally make the inner chamber of workpiece 9 and cylindrical sidewall shaping.
