Abstract
The motion of roller is decomposed into two mutually perpendicular ones completed by driving hydraulic transmission mechanism controlled by one controller. The controller decomposes the motion of roller into two mutually perpendicular ones based on required outer contour curve of machined hollow product, converts the decomposed motions into corresponding hydraulic oil flow rate of the driving hydraulic transmission mechanism and controls the oil supply, so that the blank drawn by the core mold and pushed by the tail head is rolled into required hollow product. Compared with available technology, the present invention has the advantages of being precise, high in efficiency and reliable.
Description
The present invention relates to a kind of pressure forming processing technology and device.
The existing device of making the hollw article of pot body class generally adopts hydraulic drawing press.Adopt the hollw article of hydraulic drawing press manufacturing pot body class to have following shortcoming: 1, the vessel appearance is subjected to the restriction of processing conditions, can only process the identical vessel of wall thickness dimension, the vessel moulding of being made is single, stiff, can not satisfy the requirement that one-shot forming processing has the distinctive appearance vessel of different wall size; 2, spillage of material is big, must compress the limit of blank during owing to stretching, and behind the drawing and forming, the limit of blank abandons with regard to cut, so with regard to consume material; 3, die cost is big, produce the product of different size and must make corresponding punch, die earlier, and the manufacturing cost of punch, die is than higher.
In order to overcome the above-mentioned shortcoming of hydraulic drawing press, people have invented a kind of rotation-formed technology again, and this technology is to affect the blank that is clamped by the tail top by the core that is rotating, and the sheet material that will rotate by roller is pressed into required shape then.Adopt this technology to solve the above-mentioned defective of hydraulic drawing press theoretically.But how this technology is realized effectively that people are also among constantly groping.
Goal of the invention of the present invention is to provide a kind of can effectively realize flow forming and molding process and device thereof rotary press modelling, that device therefor is simple in structure, reliable, production efficiency is high.
Flow forming and molding process of the present invention is to realize like this, comprise by the core that is rotating and affect the blank that is clamped by the tail top, the blank that will rotate by roller is pressed into required shape then, its special feature is the motion of roller is resolved into two orthogonal motions and driven realization by hydraulic gear, and the movement travel of hydraulic gear is controlled by control device, control device is according to the appearance curve of the hollw article of the pot body class of moulding to be processed, the motion that will carry out roller is resolved into two orthogonal motions and these two motion conversions is become to drive the flow of the hydraulic oil of corresponding hydraulic gears action, control device is according to the fuel supply flow rate of the flow parameter of this hydraulic oil control to two orthogonal hydraulic gears then, roller can will be affected by the core that is rotating and is pressed into the hollw article of the pot body class of required form by the blank that the tail top clamps.
Here, the motion that realization will be carried out roller, resolve into two orthogonal motions, and these two motion conversions are become to drive the method for flow of the hydraulic oil of corresponding hydraulic gears action, can be to realize with hydraulic follow-up valve and the curve template identical with the appearance curve of the hollw article of pot body class, the valve rod that is about to the hydraulic follow-up valve leans against on the curve of template, and make the motion of hydraulic follow-up valve and the synchronized movement of two hydraulic gears, like this when the curve of the movement locus of roller and template is inconsistent, the valve rod of hydraulic follow-up valve can be adjusted the flow that is transported to the hydraulic oil on the hydraulic gear immediately, make the movement locus of roller consistent, reach the effect of profiling with template curve.Thereby blank is pressed into the hollw article of the pot body class of required form by roller.
Here, control for convenience, during operation, wherein a hydraulic gear is the constant speed motion.Like this, the hydraulic follow-up valve only need be adjusted the flow velocity that is fed to the hydraulic oil on another hydraulic gear and just can make the running orbit of roller consistent with the curve of template.
Rotary press modelling device of the present invention is to realize like this, comprise frame, power drive mechanism, core, the tail top, tail top clamp mechanism, roller, the roller feed arrangement, power drive mechanism, tail top clamp mechanism relatively is fixed on the frame, the roller feed arrangement is fixed on the frame of power drive mechanism and clamp mechanism side, tail top, core is fixed on the main shaft of power drive mechanism, the tail top is fixed on the clamp mechanism of tail top, roller is fixed on the roller feed arrangement, its special feature is that the roller feed arrangement is mainly by rolling wheel support, radially-directed guide rail and planker, axially directed guide rail and planker, power transmission oil cylinder radially, axial power transmission oil cylinder, controlling organization constitutes, rolling wheel support is movably connected in the radially-directed guide rail, on the planker and by radially power transmission oil cylinder drive, the radially-directed guide rail, planker is movably connected in axially directed guide rail, drive on the planker and by axial power transmission oil cylinder, controlling organization is controlled radially, axial power transmission cylinder action.
