Abstract
The invention provides a kind of pressure processing method, promptly a kind of metal plate material moulding process.Punch (or die) just is installed on forcing press, and what replace another half module is one of interior dress power transmission medium and holds frame, it is characterized in that the power transmission medium is a viscoplastic material, and visco-plasticity macromolecular material particularly is as synthetic rubber, plastics etc.This process molding is easy, and it is big that medium transmits pressure, and drawing coefficient obviously is better than other forming method, thereby plastic more unmanageable alloy metal plate material, can draw Flange Plane and draw axis off plumb part, the power transmission medium is reusable, and is free from environmental pollution.
Description
The invention belongs to a kind of pressure processing method, relate in particular to a kind of metal plate stuff half-module forming technology.
In the small lot of modern industry especially aerospace field, many kinds, more unmanageable parts are produced, there are not mould and half module forming technique with nonmetallic materials as the metal plate material of power transmission medium, development was rapidly arranged since the seventies.Resemble with water is the explosive forming of power transmission medium, with oil is the rubber pocket shaping and the topping up draw forming of power transmission medium, and be that the dieless bulging ball of medium is shaped and is the flexible die forming of medium with rubber or polyurethane with water or oil, from exploratory stage development to the practical stage.But these forming technologies all exist such or such shortcoming.As: all need special equipment these technologies, and these equipment cost an arm and a leg mostly; Because the sealing difficulty has limited the transferable pressure of power transmission medium, thereby has had influence on the shaping of difficult-to-machine material; Elastic fluid is difficult to satisfy the requirement of local large deformation in the workpiece during as flexible die forming; During as the power transmission medium, liquid splash under situation is broken in shaping involves operator and contaminated environment with liquid, and medium can not reuse.
The object of the present invention is to provide to overcome above-mentioned shortcoming, bring into play a kind of metal plate stuff half-module forming technology of its strong point and practical and effective.
The technical solution of this metal plate stuff half-module forming technology is as follows:
A kind of metal plate stuff half-module forming technology is equipped with punch (or die) and reaches the appearance frame that substitutes another half module on forcing press, the power transmission medium that it is characterized in that holding in the frame is a viscoplastic material.
The viscoplastic material that this metal plate stuff half-module forming technology is adopted is the visco-plasticity macromolecular material.
The visco-plasticity macromolecular material that this metal plate stuff half-module forming technology is adopted can be the rubber that synthesizes, one or more combinations in the resin.
Below in conjunction with embodiment and accompanying drawing the present invention and the course of work thereof are described further.
Accompanying drawing is embodiments of the invention.Oil cylinder 2 is arranged at the top of the small-sized hydraulic machine 1 among the figure, the lower end of oil cylinder is equipped with punch 3, the workbench central authorities of hydraulic press are equipped with and substitute the appearance frame 6 that die is used, hold frame top blank holder 4 is arranged, hold in the frame and be placed with a kind of visco-plasticity power transmission medium-polyvinyl acetate 7, metal plate material 5 to be formed places blank holder 4 and holds between the frame 6, can produce different precompressions by pressing plate 8 screws of regulating on the blank holder 49, thereby influence the internal pressure that the visco-plastic medium in the forming process produces, force the metal plate material to be shaped by the punch shape, unnecessary medium can flow out from control section.
The molding of this metal plate stuff half-module forming technology is easy, equipment is simple, the pressure that medium transmits is big, can reach the 800-1000 crust, drawing coefficient obviously is better than other manufacturing process, thereby can be shaped more unmanageable alloy metal plate material, can draw Flange Plane and draw axis off plumb part, the power transmission medium is reusable, and disadvantages such as nonpollution environment are current a kind of comparatively ideal metal plate material manufacturing process.
