Embodiment Construction

[0008] The present invention will be further described below in conjunction with accompanying drawing.

[0009] The structure of the present invention is as figure 1 As shown, it includes a frame 1 and a workbench 2. The frame 1 includes a machine base 3 and a column 4 fixed on the machine base 3. The upper part of the column 4 is fixed with an upper side beam 5 and the lower part is fixed with a lower side beam 6. The workbench 2 is fixed on the lower side beam 6, the upper side beam 5 is fixed with a guide post 7 and a pull-back beam 8 sleeved on the guide post 7, and the lower part of the upper side beam 5 is fixed with a hydraulic cylinder 9, which is characterized in that: the column 4 and The racks 1 are connected by slide blocks 10 .

[0010] There are many specific application approaches of the present invention, and the above description is only a preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, some...

Abstract

The invention provides an adjustable hydraulic machine. The hydraulic machine comprises a rack and a working table. The rack comprises a machine seat and a stand column fixed to the machine seat; an upper side beam is fixed to the upper portion of the stand column, and a lower side beam is fixed to the lower portion of the stand column; the working table is fixed to the lower side beam, and guide columns (7) and a pulling-back beam arranged on the guide columns in a sleeving manner are fixed to the upper portion of the upper side beam; and a hydraulic cylinder is fixed to the lower portion of the upper side beam, and the stand column is connected with the rack through a sliding block. Through the sliding block, the stand column can vertically displace on the rack, and therefore the stroke of the hydraulic machine can be adjusted, and the aim of flexibly machining pipe fittings of different specifications is achieved.

Description

technical field [0001] The invention relates to the field of hydraulic machines, in particular to an adjustable hydraulic machine. Background technique [0002] In the process of pressing steel pipe fittings, especially for pipe fittings with large diameter pipes and thick walls, the pressing surface of small tonnage presses [0003] Small volume, low air pressure height, and small stroke, which cannot meet the drawing design and engineering requirements, so a large press with a large pressing area, a large starting height, and a large stroke is required, and a large press with a large pressing area and a high starting height is used to make up for it in production. Insufficient equipment and technology for pressing large pipe fittings during processing. For pipe fittings of different specifications, hydraulic presses of different specifications need to be used, which is cumbersome to replace and increases production costs. Contents of the invention [0004] In order...
