Abstract
The utility model discloses an oil hydraulic press with an end closure, which comprises an oil hydraulic press with an end closure, a high-pressure water bag is positioned on the upside of a movable platform in a lower die holder of the oil hydraulic press with an end closure, and a safe pressure-limited valve is arranged on the high-pressure water bag; a blanking holding cylinder is arranged below a middle platform along the periphery of an upper die; a blank holder is arranged on the underside of the beading cylinder; a pressure-limited valve is arranged on the blanking holding cylinder; and the inner wall above the inner step of the upper port of a bottom tire extends outward to present a pipe socket shape. The utility model has good cushioning effect during the stamping process, causes a blank material to be uniformly forced, and is benefit for improving the product quality.
Description
Technical field:
The utility model relates to the forming press of metal extruding, particularly a kind ofly is used for head pressing, metal material stretches, proofreaies and correct and other press-fits the end socket hydraulic press of part moulding.
Background technology:
Existing end socket hydraulic press, be that three platforms in upper, middle and lower are installed on a column support, at upper mounting plate and middle platform central authorities a master cylinder is installed, a plurality of auxiliary oil cylinders are installed around the master cylinder, master cylinder lower end below middle platform center is connected with patrix, the patrix periphery is equipped with a plurality of flanging supporting legs, on each flanging supporting leg base plane, be connected with a blank holder, a movable platform is installed on lower platform, die shoe is installed on the movable platform, be placed with one with right angle step in the die shoe upper surface at the bottom of tire.During work, earlier patrix is lifted with oil cylinder, on die shoe, put blank then well, handle each oil cylinder at last the blank punch forming.Defectives such as the end socket hydraulic press of this structure is not provided with because cushion in the end of blank bottom tire, easily causes drawing crack, bulge when the compacting light sheet products, and periphery is inhomogeneous influence product quality.
Summary of the invention:
The purpose of this utility model provides a kind of phenomenon, guaranteed end socket hydraulic press of product quality such as product drawing crack, bulge and circumference be inhomogeneous that be difficult for causing.
Art designs scheme of the present utility model is, it includes an end socket hydraulic press, it is characterized in that: in the die shoe of end socket hydraulic press, above movable platform, be placed with a high pressure water pocket, the high pressure water pocket is provided with pressure-limiting safety valve, below middle platform, the flanging cylinder is installed along the patrix periphery, on the flanging cylinder bottom face blank holder is installed, on the flanging cylinder pressure limiting valve is installed.The above inwall of step outwards is bell mouth shape in the end tire upper port.Good buffer effect when the utlity model has punching press makes blank stressed evenly, the advantage that helps improving the quality of products.
Description of drawings:
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the structural representation of end tire upper port.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, the utility model is improvements over the prior art, it includes column support 2 and goes up the upper mounting plate of fixing with nut 11 1, middle platform 3, lower platform 9, on upper mounting plate and the middle platform master cylinder 10 is installed, auxiliary oil cylinder 12, the master cylinder lower end of central authorities is equipped with film 13 on below middle platform, on lower platform, a die shoe 17 is installed through movable platform 18, it mainly improves is to be placed with a high pressure water pocket 14 on die shoe is used for movable platform, pressure-limiting safety valve 8 is housed on the high pressure water pocket, below middle platform, flanging cylinder 4 is installed along the patrix periphery, the flanging cylinder is equipped with blank holder 6 on the lower surface, and pressure limiting valve 5 is installed on the flanging cylinder.Through above-mentioned improvement, blank 7 each one in punching course is stressed evenly, can effectively avoid product defects.Above-mentioned end socket hydraulic press can also be processed into bell mouth shape with the inwall more than the step in the port of end tire 16, helps the rapid placement of tire core 15, has improved speed of production.
