Prestressed steel wire winding frame and ceramic press machine

Abstract

An embodiment of the invention discloses a prestressed steel wire winding frame and a ceramic press machine. The prestressed steel wire winding frame comprises an upper beam, a first standing column,a second standing column, a lower beam and a pre-tightening steel wire and is characterized in that the first standing column and the second standing column are symmetrically arranged between the upper beam and the lower beam to form a sealed frame; the pre-tightening steel wire winds the outer side of the sealed frame to form pre-tightening force on the sealed frame. By the prestressed steel wirewinding frame, the pre-tightening wire generates vertical and horizontal pre-tightening force on the sealed frame, the sealed frame can bear vertical and horizontal load, the structure of the sealedframe is reinforced, and the different-direction work load bearing requirements of the pressing process of different press machines.

Description

technical field [0001] The invention relates to a bearing frame of heavy machinery, in particular to a prestressed steel wire winding frame and a ceramic press. Background technique [0002] Currently known prestressed steel wire winding bearing frame such as figure 1 As shown, the steel wire 4' bundles the upper beam 1', the column 2' and the lower beam 3' into a closed bearing frame. [0003] This load-carrying frame structure has the advantage of good fatigue resistance, and is widely used in many heavy machinery fields, and is mainly used to carry vertical working loads 5'. [0004] However, the prior art has the following disadvantages: the column has pre-tightening protection in the vertical direction, but has no pre-tightening protection in the horizontal direction, and can only rely on the friction between the column and the upper and lower beams to bear the horizontal load 6'. With the development of ceramic presses, ceramic presses have changed from simply applyi...

Problems solved by technology

[0004] However, the prior art has the following disadvantages: the vertical column has a pre-tightening protection force in the vertical direction, but there is no pre-tightening protection force in the horizontal direction, and can only rely on the friction between the column and the upper and lower beams to bear the horizontal load 6'

With the existing structure, when the horizontal load 6' is large, a large vertical pressure is required to generate sufficient friction, so the preload coefficient needs to be increased a lot, which increases the weight of the frame and causes waste

In addition, based on the working characteristics of this type of brick press, while generating horizontal loads, it will simultaneously generate vertical loads, thus reducing the friction generated by pre-tightening, and easily causing lateral displacement of the upper beam, affecting the pressed product. the quality of
