Multi-directional die forging process testing device

Abstract

The invention provides a multi-directional die forging process testing device, and relates to the technical field of machinery manufacturing. The multi-directional die forging process testing device comprises a main machine frame, a hydraulic pump station, an upper main press cylinder, a front oil cylinder, a back oil cylinder, a left oil cylinder, a right oil cylinder, a valve group, a lifting oil cylinder, a movable transverse beam and a lower main press cylinder, wherein the main machine frame comprises a nylon cushion, support leg bodies, a pull rod, a lower transverse beam, an upper transverse beam and a worktable, the upper main press cylinder is fixedly arranged in an inner hole which is formed in the upper transverse beam, the lower main press cylinder is fixedly connected with the lower transverse beam, a piston rod of the lower main press cylinder penetrates through a center hole which is formed in the worktable, the front oil cylinder, the back oil cylinder, the left oil cylinder and the right oil cylinder are respectively and fixedly arranged in inner holes which are formed in the movable transverse beam through flanges, a cylinder body of the lifting oil cylinder is fixedly arranged on the upper surface and the lower surface of the upper transverse beam through screws, lug rings of the lifting oil cylinder are connected with the upper surface of the movable transverse beam, and the hydraulic pump station is connected with the upper main press cylinder, the front oil cylinder, the back oil cylinder, the left oil cylinder, the right oil cylinder, the lifting oil cylinder and the lower main press cylinder through the valve group and pipelines. The multi-directional die forging process testing device has the advantage that the forging press point positions in the horizontal direction are adjusted through the vertical movement of the movable transverse beam.

Description

technical field [0001] The patent of the present invention relates to the technical field of mechanical manufacturing, in particular to a multi-directional die forging process test device. Background technique [0002] Multi-directional die forging is an advanced internal high pressure forming manufacturing technology. At present, multi-directional die forging has become the production basis of machinery manufacturing, iron and steel metallurgy, petrochemical industry, ship vehicles and other industries, and has been widely used in industries. With the continuous development of forging technology, the shape and process of forgings are becoming more and more complex, which also puts forward higher requirements for multi-directional die forging devices. [0003] At present, the multi-directional die forging device commonly used in industry is mainly composed of main frame, horizontal frame, mold clamping cylinder, horizontal cylinder parts, ejector parts and base. The horizon...

AI Technical Summary

Problems solved by technology

Therefore, in actual production, the horizontal cylinder only plays the role of mold clamping, and cannot be used for forging in the horizontal direction.

At the same time, when multi-directional die forging is performed on large forgings, the problem of uneven force in the horizontal direction may also occur, which seriously affects the processing accuracy of the multi-directional die forging device
