Description

Technical Field

[0001] The utility model relates to the field of hydraulic drive equipment, in particular to a multi-directional hydraulic drive mechanism. Background Art

[0002] In hydraulic drive equipment, the driving mode is generally vertical. In actual processing, the product also involves lateral processing. The existing practice is generally to process the first process on the first hydraulic equipment and then transfer to the second hydraulic equipment to process another process. This processing method has a long time cycle and low production efficiency.

[0003] Of course, there are also multi-directional hydraulic drive mechanisms currently available, but they are mainly aimed at small-tonnage hydraulic machinery. When the tonnage is larger (for example, 1 ton), the processing involved, in addition to stability, also involves issues such as stamping accuracy and assembly accuracy. The main factors are the reaction force of the mechanism and mechanical interference. Utility Model Content

[0004] The main purpose of the utility model is to provide a multi-directional hydraulic drive mechanism, which aims to realize processing of multiple positions at one workstation, and has a stable structure and is easy to assemble.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes a multi-directional hydraulic drive mechanism, comprising:

[0006] frame;

[0007] A base, the base being arranged at the lower part of the frame;

[0008] A main hydraulic device, which is arranged above the base and can be switched between a position close to the base and a position far from the base;

[0009] The side hydraulic devices are arranged at two sides of the base, and the two side hydraulic devices can be switched between positions close to each other and positions far away from each other.

[0010] In large hydraulic devices, only a single vertical direction of workpiece processing can be performed, that is, only up and down strokes are available, thereby realizing vertical processing of workpieces; this application sets side hydraulic devices on both sides of the base. When the product needs to be processed on both sides at the same time, it can realize simultaneous processing in the vertical and horizontal directions, or processing in the horizontal direction after the vertical processing is completed, or processing in the vertical direction after the horizontal processing is completed, which effectively improves the processing applicability.)

[0011] That is, it can form hydraulic molding in multiple directions, realizing multiple uses of one machine. BRIEF DESCRIPTION OF THE DRAWINGS
