Problems solved by technology

However, in the manufacture of ultra-large tonnage presses, there is the same problem as the traditional prestressed steel wire wound ceramic presses that the parts are overweight and overweight, making manufacturing, assembly, and transportation extremely difficult
Moreover, oil channels are also opened in the high stress area, which affects the strength and life of the frame

Abstract

The invention discloses a ceramic pressing machine adopting a multi-connection prestressed steel wire winding plate frame structure. A main rack is constituted by connecting a plurality of plate frame units in parallel; each plate frame unit comprises an upper crossbeam, a base, a left vertical column and a right vertical column, wherein the left vertical columns and the right vertical columns are arranged between the upper crossbeams and the bases; each plate frame unit is formed by winding steel wires; the upper cross beams, the bases, the left vertical columns and the right vertical columns form pressing spaces in an enclosed mode; oil path plates, main oil cylinder components and main plates are arranged in the pressing spaces; oil tanks are arranged at the tops of the upper crossbeams; and liquid filling channels are formed between the oil tanks and the oil path plates. According to the scheme, most of key parts of the rack are located in the pressure stress state, thus the hidden danger of fatigue crack propagation is eliminated, the advantage of the small load fluctuation quantity is achieved, the fatigue life is long, and stress concentration caused by upper beam opening of a traditional prestressed steel wire winding pressing machine is avoided.

Description

technical field [0001] The invention relates to the field of ceramic presses, in particular to a ceramic press adopting a multi-connected prestressed steel wire winding plate and frame structure. Background technique [0002] Traditional prestressed steel wire winding ceramic press ( Figure 1-1-2-2 ) The main frame has only one main frame, and the main frame is made up of a steel wire wound upper beam, a base and a column. The stress state of the entire frame is changed by the prestressed steel wire winding layer, so that the load fluctuation of the frame is small, which is beneficial to improve the fatigue life of the frame. There are currently two arrangements for ceramic presses with this structure: Figure 1-1-1-2 It is a built-in oil tank. The frame of this structure has a built-in oil tank cavity cast inside the upper beam. The cavity needs to be manually polished, and it is difficult to clean the surface. At the same time, there is a circular oil channel in the lowe...
