Problems solved by technology

[0002] In the plastic forming technology of modern manufacturing, the hydraulic press occupies a very important position, such as Figure 14 The hydraulic machine is a typical hydraulic machine with the upper part being double-acting and the lower part being single-acting. It consists of a liquid-filled cylinder 64, a master cylinder 65, an upper beam 66, a blank holder cylinder 67, a main slider 68, a binder slider 69, and a manipulation Device 70, hydraulic system 71, workbench 72, and ejection cylinder 73. This hydraulic machine adopts the edge-pressing slider 69 above the workbench 72 and the main slider 68 to form. Cylinder 73, and the ejector cylinder can only play the role of jacking material, and cannot perform composite forming of reverse blanking at the same time; it is used for closed forging, sheet metal drawing, finishing, trimming, punching, flanging, and among them In order to simplify the process, improve the forming efficiency, material utilization rate and workpiece precision, etc., it needs to be carried out on the hydraulic press with double action up and down, which increases the complexity of the hydraulic press structure and manufacturing cost, and there are still Some technical problems need to be solved urgently

Embodiment Construction

[0038] The specific structure of the present invention will be described in further detail below in conjunction with the embodiments given in the accompanying drawings.

[0039] refer to Figures 1 to 4 , the four-column adjustable hydraulic press is double-moving up and down, the upper beam 1, the main slider 9, the edge slider 13, the workbench 14, the floating workbench 15 and the lower beam 21 are mounted on the four columns 8, The upper beam 1, the workbench 14, the lower beam 21 and the column 8 are all fastened with nuts, and the strength and rigidity of the overall structure of the hydraulic press must be ensured. Between 14, it is a sliding fit with the column 4, and to ensure good fit accuracy and wear resistance, the floating workbench 15 is installed between the workbench 14 and the lower beam 21, and it is also a sliding fit with the column 8, and the floating work The table limit nut 16 can limit the floating table 15 to a predetermined height, and a T-shaped fr...

Abstract

An adjustable hydraulic press with movable upper and lower units is composed of vertical columns, upper transverse beam, primary slide block, the slide block for pressing edge, bench, floating bench, lower transverse beam, the primary and secondary cylinders fixed to upper transverse beam, and a push-up cylinder fixed to lower transverse beam for driving said floating bench.

Description

Technical field: [0001] The invention relates to a hydraulic press for metal plastic processing, especially for punching, finishing, flanging, plate drawing, closed forging and metal plastic cold forming or hot forming with several processes combined. Hydraulic Press. Background technique: [0002] In the plastic forming technology of modern manufacturing, the hydraulic press occupies a very important position, such as Figure 14 The hydraulic machine is a typical hydraulic machine with the upper part being double-acting and the lower part being single-acting. It consists of a liquid-filled cylinder 64, a master cylinder 65, an upper beam 66, a blank holder cylinder 67, a main slider 68, a binder slider 69, and a manipulation Device 70, hydraulic system 71, workbench 72, and ejection cylinder 73. This hydraulic machine adopts the edge-pressing slider 69 above the workbench 72 and the main slider 68 to form. Cylinder 73, and the ejector cylinder can only play the role of jac...
