Abstract
A finish forging die for forging an aluminum alloy wheel comprises an upper die plate and a lower die plate. A lower die is fixed above the lower die plate. An upper die is fixed below the upper die plate. The upper die comprises an upper die core, and the upper die core is sleeved with an upper die sleeve. A circle of notch is formed in the outer wall of the upper portion of the lower die. A flash reserving cavity is formed between the inner wall of the upper die sleeve and the notch of the lower die. A lower ejector rod is arranged at the center of the lower die. An upper ejector rod is arranged at the center of the upper die core. The problems that iron materials are not even and a die is not in place when the quantity of materials is large are solved through the flash reserving cavity formed between the inner wall of the upper die sleeve and the notch of the lower die; a workpiece can be pressed on a lower die core through the upper ejector rod arranged right at the center of the upper die core so that the die can be released, and damage caused when the workpiece collides with the die is avoided; the workpiece is ejected out of the lower die core through the lower ejector rod arranged right at the center of the lower die core, and therefore the forging process is achieved; compared with a traditional die, the finish forging die has the advantages of being free of die holding, easy to release and not prone to strain.
Description
Technical field
The present invention relates to a kind of mould, particularly a kind of finish-forging die of reflectal wheel.
Background technology
Aluminum-alloy wheel adopts forging mode to start from the beginning of this century at home, belongs to novel process technology.Reflectal wheel has been widely used in the vehicles such as passenger vehicle, trailer, oil truck, engineering truck, school bus, but the forging mold of reflectal wheel is at home also in the stage of growth now, now with traditional finish-forging die, be made of one,, when blank, often there is the problem that blank is inhomogeneous and mould closure is not in place in inconvenient cleaning die cavity and maintenance; Existing traditional finish-forging die die sinking process is the demoulding after first molding, makes the collision of the easy generation of workpiece and mould, causes the damage of workpiece.Meanwhile, now serious with traditional finish-forging die waste material, be difficult for the demoulding, inconvenient dismounting and change wear-out part, forging product out, to lack material, bad mechanical property and product percent of pass lower.
Summary of the invention
The technical problem to be solved in the present invention is for the deficiencies in the prior art, proposes a kind of material-saving, is convenient to load and unload wear-out part, avoids the workpiece damage that easily bumps, and can improve the finish-forging die of the reflectal wheel of product mechanical performance.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of finish-forging die of reflectal wheel, be characterized in: comprise cope match-plate pattern and lower bolster, above lower bolster, by bottom plate, be fixed with counterdie, below cope match-plate pattern, by mounting plate, be fixed with patrix, patrix comprises with counterdie over against the upper mold core arranging, upper mold core is set with the Upper Die-sleeve being fixedly connected with mounting plate outward, the bottom of Upper Die-sleeve is sleeved on outside counterdie, in the bottom of Upper Die-sleeve, be provided with the seam convex engaging with bottom plate, in upper mold core, between Upper Die-sleeve and counterdie, form airtight forging and stamping die cavity, in the external wall of upper portion of counterdie, be provided with a circle breach, between the inwall of Upper Die-sleeve and counterdie breach, form the reserved chamber of overlap, in the center of counterdie, be provided with the upwards lower push rod of jack-up workpiece, in the center of upper mold core, be provided with the upper ejector pin that ejects workpiece downwards, bottom at upper ejector pin is provided with, and is provided with for determining the positioning boss of workpiece centre bore dia on taking over a business.
The technical problem to be solved in the present invention can also be come further to realize by the following technical programs, and one end that described lower push rod stretches out lower bolster is downwards provided with jacking nut I, is provided with the back-moving spring I being sleeved on outside lower push rod between jacking nut I and counterdie.
The technical problem to be solved in the present invention can also be come further to realize by the following technical programs, and one end that described upper ejector pin protrudes upward cope match-plate pattern is provided with jacking nut II, is provided with the back-moving spring II being sleeved on outside upper ejector pin between jacking nut II and upper mold core.
The technical problem to be solved in the present invention can also be come further to realize by the following technical programs, is provided with the fork pockets that coordinates transportation with fork truck on lower bolster, and fork pockets is symmetrically distributed with two groups and every group and is respectively equipped with two.
Compared with prior art, utilization of the present invention is arranged on the reserved chamber of overlap between Upper Die-sleeve inwall and counterdie breach, has solved iron charge inhomogeneous and chat multi-mould problem not in place; Utilization is arranged on the RC upper ejector pin of upper mold core, workpiece can be pushed down in lower mold core, and patrix backhaul, realizes knockout course, the damage of having avoided workpiece and mould to cause because bumping; Utilization is arranged on the RC lower push rod of lower mold core, and workpiece is ejected to lower mold core, realizes a forging and stamping process, compares traditional moulds, has advantages of not embrace mould, the easily demoulding, do not pull.Material-saving of the present invention, be convenient to load and unload wear-out part, can guarantee the mechanical performance of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
A kind of finish-forging die of reflectal wheel, comprise cope match-plate pattern 1 and lower bolster 13, above lower bolster 13, by bottom plate 15, be fixed with counterdie 14, below cope match-plate pattern 1, by mounting plate 2, be fixed with patrix, patrix comprises with counterdie 14 over against the upper mold core 3 arranging, the outer Upper Die-sleeve 8 being fixedly connected with mounting plate 2 that is set with of upper mold core 3, the bottom of Upper Die-sleeve 8 is sleeved on outside counterdie 14, in the bottom of Upper Die-sleeve 8, be provided with the seam convex engaging with bottom plate 15, between upper mold core 3, Upper Die-sleeve 8 and counterdie 14, form airtight forging and stamping die cavity; In the external wall of upper portion of counterdie 14, be provided with a circle breach, between the inwall of Upper Die-sleeve and counterdie breach, form the reserved chamber 16 of overlap, in the center of counterdie 14, be provided with the upwards lower push rod 10 of jack-up workpiece, in the center of upper mold core 3, be provided with the upper ejector pin 6 that ejects workpiece downwards, bottom at upper ejector pin is provided with 7, is taking over a business on 7 to be provided with for determining the positioning boss of workpiece centre bore dia.Described upper mold core 3 and Upper Die-sleeve 8 adopt bolted on cope match-plate pattern 1, are convenient to dismounting and safeguard mould.Workpiece after blocking is placed on to counterdie place, forging machine puts upper mold core and Upper Die-sleeve compacting in place, after having suppressed, by upper ejector pin, workpiece is pushed down on counterdie, patrix backhaul, realize the demoulding, compare with the demoulding after the first molding of traditional finish-forging die, avoided workpiece and mould to bump and the damage that causes; Finally by lower push rod, workpiece is ejected to counterdie.Realize a forging and stamping process.
