Embodiment Construction

[0037] combined with Figure 1 to Figure 12 The present invention is described in further detail.

[0038] Such as figure 1 As shown, the present invention mainly includes a vertical main working cylinder 2, a left horizontal cylinder 3, a right horizontal cylinder 4 and an ejection cylinder 5 installed on a stressed frame 1.

[0039]The stress frame 1 is welded by high-strength steel plates, including two main stress plates 16 with "mouth" shapes on the front and rear, upper beams 11, lower beams 15, box-shaped columns 13; upper beams 11 and lower beams 15 are placed horizontally up and down, and the box-shaped columns are located between the upper beam 11 and the lower beam 15, one on the left and one on the left and right, and the main force plate 16 covers the front and rear sides, leaving a "mouth" shaped window. A workbench 14 is fixed above the lower beam 15 of the stressed frame 1 .

[0040] The vertical main working cylinder 2 is a special piston-type double-acting...

Abstract

The invention mainly discloses a multidirectional numerical control hydraulic press for metal plasticity forming. A vertical main working cylinder, two horizontal cylinders and a push-out cylinder are mounted on a stress frame; a punching cylinder is combined inside the vertical main working cylinder stroking downwards, the two horizontal cylinders are a left horizontal cylinder and a right horizontal cylinder both of which stroke in the opposite directions, and each horizontal cylinder is combined with a quick-speed cylinder; the push-out cylinder is positioned below the vertical main working cylinder and adopts an inverted cylinder acting structure; and all cylinder bodies are controlled by a hydraulic control system. In the invention, an oil pump is used for direct driving, numerical control closed loop servo control is achieved, and meanwhile, axial loading and transverse loading are performed at the same time, so as to form high-precision parts with branch shaped or cavity-like complex structures in different directions.

Description

technical field [0001] The invention belongs to the technical field of metal plastic forming hydraulic presses, in particular to a multi-functional and high-performance numerical control hydraulic press which adopts oil pump direct transmission and numerical control closed-loop servo control, and can simultaneously realize multi-directional, isothermal and precise forming. Background technique [0002] So far, most of the existing metal plastic forming hydraulic presses are designed as presses for a certain process object and single function, with narrow process range and low press performance. [0003] For example, multi-directional die forging hydraulic presses are generally driven by water pumps and accumulators, and it is difficult to achieve high-precision automatic control; although some use direct transmission of oil pumps, they do not realize digital servo control of working cylinders, and multi-working cylinders with multi-directional forming The force and energy pa...
