Free forging oil press rack

Abstract

The invention discloses a free forging oil press rack. The free forging oil press rack comprises an upper cross beam (1), a lower cross beam (2) and two upright columns (3), which are formed by a welding process, wherein the two upright columns (3) are vertically symmetrically arranged at two sides of the free forging oil press rack; the upper cross beam (1) is arranged at the top of the free forging oil press rack, is positioned between the two upright columns (3) and is pre-tightened and assembled together with the two upright columns by upper beam pull rods (4); multiple upper beam rectangular keys (5) are embedded in rectangular key slots reserved in the upper ends of the upper cross beam (1) and the upright columns (3); the lower cross beam (2) is arranged at the bottom of the free forging oil press rack, is positioned between the two upright columns (3) and is pre-tightened and assembled together with the two upright columns by lower beam pull rods (6); multiple lower beam rectangular keys (7) are embedded in rectangular key slots reserved at the lower ends of the lower cross beam (2) and the upright columns (3). The free forging oil press rack has the advantages of simple structure, light weight, low cost, short manufacturing period, easiness in manufacturing and machining and the like.

Description

technical field [0001] The invention belongs to the technical field of hydraulic presses, in particular to a free forging hydraulic press frame. Background technique [0002] With the continuous development of contemporary electric power, steel, petrochemical, weapons and other industries, the demand for large-scale equipment in foreign and domestic markets is increasing, such as large-scale nuclear power parts, parts required by military industry, and aerospace parts. Parts usually need to be processed by a hydraulic press, while the frame of a traditional hydraulic press, for example, the frame of a large free-forging hydraulic press, is made of steel castings. After the size of the processed parts is increased, the size of the frame of the hydraulic press It is also increasing. Due to the heavy weight of each component of the frame and the complex internal structure, higher requirements are placed on the casting equipment when manufacturing this frame, and the casting pro...

[0002] With the continuous development of contemporary electric power, steel, petrochemical, weapons and other industries, the demand for large-scale equipment in foreign and domestic markets is increasing, such as large-scale nuclear power parts, parts required by military industry, and aerospace parts. Parts usually need to be processed by a hydraulic press, while the frame of a traditional hydraulic press, for example, the frame of a large free-forging hydraulic press, is made of steel castings. After the size of the processed parts is increased, the size of the frame of the hydraulic press It is also increasing. Due to the heavy weight of each component of the frame and the complex internal structure, higher requirements are placed on the casting equipment when manufacturing this frame, and the casting process will be more stringent, resulting in more manufacturing processes and lower costs. High, long construction period, easy to produce waste products, so a new process has to be considered to manufacture the frame of large free forging hydraulic press
