Abstract
The invention discloses a zinc alloy large-plane die casting dressing technology. The technology comprises the following steps: utilizing a jig consisting of an upper clamping plate and a lower clamping plate to lock and shape a die casting, thus the die casting is in an elastic deformation state and the flatness of the die casting is up to 10-15 microns; placing the jig in an oven, and heating so that the die casting is subjected to elastic deformation, the stress is relieved, the demand on the flatness can be met; opening the door of the oven, taking out the die casting, and cooling the die casting naturally to the room temperature; and loosening the jig, and taking out the die casting for the next working procedure. The technology provided by the invention is simple in operation, and has the advantages of good stability, high production efficiency, great market value and huge market potential, no need of plentiful manpower and material resources and no damage to surface of the product; the stress of the product can be eliminated automatically, the product stability is good, the product can not deform again; and large-plane die castings can be effectively shaped, and the high demands of modern production on the product quality and the production efficiency can be met.
Description
Technical field
The present invention relates to die casting technology field, the big plane of particularly a kind of zinc alloy die casting shaping process.
Background technology
Deformation of body is divided into two kinds of recoverable deformation and viscous deformation, and wherein recoverable deformation can be recovered, and viscous deformation then cannot recover.The result of the general shaping expectation of die industry die casting is viscous deformation, promptly allows the product leveling just finalize the design afterwards.
Zinc alloy diecasting needs release because the structure of self causes inside to contain a large amount of stress, therefore the situation of its depanning after strain is comparatively general, traditional smoothing plastic model all is to adopt manual processing, promptly beat out gently with rubber hammer, allow product slowly discharge stress, this mode of operation causes product surface easily and causes damage, and production efficiency is not high, the phenomenon of doing over again is comparatively serious, often become the mass-produced bottleneck operation of restriction product, can not satisfy the requirement of modern production product quality and production efficiency.
Summary of the invention
Purpose of the present invention is by the design of the big plane of a kind of zinc alloy die casting shaping process, utilizes this technology not only can be quick, finishes the shaping and the shaping process of die casting efficiently, and do not need to expend lot of manpower and material resources, and is simple to operate.
For achieving the above object, the technical solution adopted in the present invention is as follows: the big plane of a kind of zinc alloy die casting shaping process, and described technology may further comprise the steps:
1, utilize the tool of forming by last lower plate that die casting locking is finalized the design, make die casting be in elastic deformation and planeness reaches the 10-15 micron, the lower surface of described train wheel bridge, the upper surface of lower plate are equipped with and the outstanding suitable clearance position of the position of bone of die casting;
2, above-mentioned tool is put into baking box and be warmed up to 150 ℃, toast after 60-70 minute, die casting generation viscous deformation discharges stress, and planeness reaches requirement;
3, open oven door, take out die casting, make die casting naturally cool to room temperature, available fans auxiliary temperature-reducing in the process of cooling is to reduce cooling time;
4, unclamp tool, die casting is taken out, die casting can enter next step operation.
Nationality has following advantage by above-mentioned technology, the present invention:
Technological operation of the present invention is simple, good stability, do not need lot of manpower and material resources, the production efficiency height does not have damage to producing the surface, automatically eliminate the stress of product, make product stability good, can not be out of shape once more, effectively solve the shaping problem of big plane die casting, satisfy the high request of modern production, have marketable value and huge market potential widely product quality and production efficiency.
Embodiment
Below in conjunction with example the big plane of zinc alloy of the present invention die casting shaping process is further elaborated:
Embodiment:
The big plane of a kind of zinc alloy of the present invention die casting shaping process, described technology may further comprise the steps:
1, utilize the tool of forming by train wheel bridge 1 and lower plate 2 that die casting 3 lockings are finalized the design, make die casting 3 be in elastic deformation and planeness reaches 10 microns, the upper surface of the lower surface of described train wheel bridge 1, lower plate 2 is equipped with and the die casting 3 outstanding suitable clearance position of the position of bone;
2, above-mentioned tool is put into baking box and be warmed up to 150 ℃, toast after 60 minutes, viscous deformation takes place in die casting 3, discharges stress, and planeness reaches requirement;
3, open oven door, take out die casting 3, make die casting naturally cool to room temperature, available fans auxiliary temperature-reducing in the process of cooling is to reduce cooling time;
4,, unclamp tool, die casting 3 is taken out, die casting can enter next step operation.
The embodiment that the present invention exemplified not is the qualification to oneself, every content that does not break away from technical solution of the present invention,, all still belong in the technical scheme scope of the present invention any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present invention.
