Hydraulic machine with multi-housing multi-directional bearing racks

Abstract

The invention discloses a hydraulic machine with multi-housing multi-directional bearing racks. The hydraulic machine comprises at least two single-housing horizontal racks, at least one single-housing vertical rack, a main working cylinder, return cylinders and horizontal cylinders. Archways of the at least one single-housing vertical rack are arranged in parallel and are fixedly connected to form a multi-housing vertical rack, and the at least two single-housing horizontal racks are arranged on the two sides of the multi-housing vertical rack in parallel and fixedly connected to form a multi-housing horizontal rack. Horizontal loads and vertical loads are loaded on the two completely independent racks of the multi-housing horizontal rack and the multi-housing vertical rack respectively, and accordingly, the requirement for the rigidity of the racks is reduced, the large-tonnage hydraulic machine rack overall weight is reduced effectively, and the hydraulic machine rack own strength is high; horizontal loads transmitted by the horizontal cylinders are born by the multi-archway horizontal rack, so that the bearing capacity is high, and the multi-housing horizontal rack cannot be damaged even if being subjected to huge loads.

Description

technical field [0001] The invention relates to a hydraulic machine, in particular to a hydraulic machine with multi-arches and multi-directional bearing frames. Background technique [0002] The frame design of heavy-duty multi-directional die forging hydraulic presses often adopts a closed frame. During the forging process, orthogonal vertical loads and horizontal loads are added to this frame. When the vertical and horizontal loads change, it will seriously affect Guidance accuracy of the rack. The utility model ZL201220227305.2 discloses a multi-directional load-bearing rack system, which loads the horizontal load and the vertical load on two completely independent racks, the horizontal rack and the vertical rack, respectively, reducing the rigidity of each rack Require. When the working load and the working surface are very large, the structure of the horizontal rack and the vertical rack will also increase, and the overall weight of the rack will increase, thereby in...

AI Technical Summary

Problems solved by technology

When the working load and the working surface are very large, the structure of the horizontal rack and the vertical rack will also increase, and the overall weight of the rack will increase, thereby increasing the manufacturing cost of the rack and causing a waste of resources, and The current multi-directional bearing frame system is that the horizontal frame is located in the vertical frame, the horizontal cylinder is installed outside the horizontal frame, and the horizontal cylinder body and the side wall of the horizontal frame are connected by snap-fit ​​connectors. This structure is horizontal All the loads of the cylinder are borne by this connecting piece, which is easy to break during use and is difficult to use for large-tonnage hydraulic presses
