Horizontally pre-tightened and combined wound plate frame type press machine rack

Abstract

The invention relates to a horizontally pre-tightened and combined wound plate frame type press machine rack, which comprises a main framework. The main framework comprises a front plate frame, a rear plate frame and a connecting framework 5 crossing the front plate frame and the rear plate frame, the front framework and the rear framework respectively comprise a plurality of independent plate frame components 1 in parallel, the front faces and the back faces of the plate frame components 1 are hollow, and the plate frame components 1 adopt a steel wire wound prestressed structure and are horizontally pre-tightened and fixed through a plurality of groups of high-strength bolt pre-tightening mechanisms 3 on the front faces and the back faces of the plate frame components 1 to form the front plate frame and the rear plate frame. The number of split components is relatively small, the split components can be manufactured easily, and the whole bearing capacity is higher.

Description

technical field [0001] The invention relates to a press frame, in particular to a transverse pretensioning combined winding plate and frame type press frame. Background technique [0002] The press frame is a heavy-duty load-bearing frame with large volume and heavy weight. In the industrial production process, it is often difficult to manufacture due to the limitation of scale and manufacturing capacity. [0003] CN2645884Y discloses a kind of "winding plate and frame type ceramic brick press", and its structure diagram is as follows: figure 1 , figure 2 As shown, the frame of the brick press machine is composed of two front and rear plate frames, and each plate frame is composed of two upright plate-like bodies 1a, 3a (or: 1b, 3b) and a middle column 2a (or: 2b ) is made by winding and pre-tightening steel wire. This kind of rack has the following disadvantages: 1. Although the entire frame has been divided into two upright plate-shaped bodies and a column in the middl...

AI Technical Summary

Problems solved by technology

This kind of rack has the following disadvantages: 1. Although the entire frame has been divided into two upright plate-shaped bodies and a column in the middle, the thicker plate bricks and columns still result in a larger volume. 2. Steel wire winding realizes the pretension of the frame in the height and width directions, which increases the load carrying capacity in the two directions, but the load carrying capacity in the thickness direction without preload cannot be compared with the other two It is important to match the load-carrying capacity of the two directions, and it is important that some loads in that direction that are already preloaded will require the unpreloaded direction to carry them together, for example, bending applied by pressing up and down from the height of the frame The load requires that the thickness direction without preload be jointly loaded, but the load capacity without preload has a large gap compared with that with preload. In this way, under the requirement of joint load, it will directly lead to the actual load capacity of the preloaded direction. significantly reduced, so the overall bearing capacity of this type of rack is not high
