Abstract
The present invention discloses a ball valve die-casting forming method and its equipment. Said equipment includes an upper die and a lower die, in the interior of upper die and in the interior of lower die a forming groove is set respectively, the centre of said forming groove is equipped with a through hole into which a guide column can be inserted, and the bottom end of said guide column is fixed on the hydraulic cylinder of a die stamping mechanism. Said invention also provides the concrete steps of said ball valve die-casting forming method.
Description
Technical field
The present invention relates to the processing method and the device of workpiece, specifically a kind of ball valve casting forming method and device.
Background technology
Generally commonly use the ball valve processing action and undertaken by Fig. 1 step, wherein, tubing E downcuts this ball valve D with a cutting knife by after counting roll extrusion part A, B rolling forming again; This kind processing mode one: in this ball valve D what process, must use the machining of complexity, not only easily cause the waste of process time, and improve production cost once more; Moreover: after this ball valve D downcuts with cutting knife C, easily form sharp keen burr, must be again with after the processing of machining machine and tools such as milling cutter, in order to do finishing ball valve D shaping processing, so not only cause outside the secondary operations, and the accuracy of this ball valve D easily produces deviation because of repeatedly processing, and is the processing method of a trouble and inconvenience in fact.
Summary of the invention
A kind of ball valve casting forming method and the device that provide at the deficiencies in the prior art is provided, and it can make ball valve be shaped fast and can prevent that ball valve from damaging accidentally because of processing, and the ball valve spoilage is reduced, the output raising.
The concrete technical scheme that realizes the object of the invention is:
A kind of ball valve casting forming method, it may further comprise the steps:
A, at first is a pedestal by a counterdie, is provided with grooving in this counterdie, and this time grooving central authorities are provided with a perforation, can wear in the what for a guide pillar admittedly, and drive guide pillar by the oil hydraulic cylinder of a punching mechanism and do the rising displacement;
B, with on this guide pillar of the sheathed what of pipe fitting to be processed, and make the compressing under the end contact what on the grooving of this pipe fitting to be processed below;
C, drive patrix with one towards arm again and press down, and wear by this guide pillar in the perforation of what patrix, with the displacement of correcting patrix, simultaneously on this patrix under grooving and the counterdie grooving to the recessed convergent of a side arc, and cooperate the guiding of this guide pillar, in order to do making this pipe fitting forming to be processed become grooving down and going up the preset shape of grooving;
D, finish in order to do the what punching press after, drive guide pillar by this oil hydraulic cylinder and do the decline displacement, should drive patrix towards arm simultaneously and do the rising displacement;
E, take out the workpiece that punching press is finished.
A kind of ball valve casting forming device is characterized in that it comprises:
One counterdie 1 is provided with grooving 2 in its counterdie 1, in order to do can installing for pipe fitting 7 to be processed, following grooving 2 central authorities are provided with a perforation, and in order to do can wearing in the what for a guide pillar 10, and the bottom of this guide pillar 10 system sets firmly on the oil hydraulic cylinder of what one punching mechanism;
One patrix 6 is provided with grooving 5 in its patrix 6, these up groove 5 central authorities are provided with a perforation 4, in order to do wearing for counterdie 1 inner guiding post 10.
The present invention reduces its damage chance of making ball valve, and with automated job, with its work flow time shortening, reaches the purpose of accelerating to improve output, reducing cost and manpower waste with this, and this industry is had tangible progressive effect in fact.

The specific embodiment
Consult Fig. 2, the device among the present invention comprises counterdie 1, patrix 6, is provided with grooving 2 in counterdie 1, and following grooving 2 central authorities are provided with a perforation, wear in the what for a guide pillar 10, and the bottom of this guide pillar 10 system sets firmly on the oil hydraulic cylinder of what one punching mechanism; Be provided with grooving 5 in patrix 6, these up groove 5 central authorities are provided with a perforation 4, can wear for counterdie 1 inner guiding post 10.
Consult Fig. 3,4, the present invention system utilizes an oil hydraulic cylinder to drive guide pillar 10 risings, after passing the perforation of counterdie 1, in order to do can be on the pipe fitting 7 sheathed what guide pillars 10 to be processed, and with punching mechanism when arm drives patrix 6 and presses down, in order to do make this pipe fitting 7 to be processed be shaped as down shape groove 2 and on preset shape between the grooving 5, after punching press is finished, drive guide pillar 10 by oil hydraulic cylinder and do the decline displacement, drive patrix towards arm simultaneously and do the rising displacement, can take out the ball valve 3 that punching press is finished.8,9 are the upper and lower end that compresses of pipe fitting 7 to be processed among the figure.
