Abstract

The invention provides a detachable press frame, which is formed by connecting an upper beam, a lower beam and upright posts, wherein the upper beam and the lower beam are arranged transversely; the upright posts are positioned on the two end parts of the upper beam and the lower beam and are arranged longitudinally; connection corners are formed at joints among the upper beam, the lower beam andthe upright posts; the upper and lower beams are detachably connected with the upright posts through a movable connecting mechanism; and the movable connecting mechanism comprises an anti-tensile stress bolt, and a nut, a flat washer, a spring washer and an anti-shear stress gasket which are connected with the anti-tensile stress bolt. The stress type of a joint part between each upright post andeach beam is changed, so that the bearing capability of the bolt is increased greatly even the shear stress on the bolt of the joint part is changed into tensile stress and the safety of a press is enhanced; simultaneously, a drilling process replaces a welding process, so that deformation of the upright posts caused by welding heat is avoided and the processing accuracy of the press frame is enhanced; moreover, the detachable press frame has a simple structure, is easy and convenient to install and is easy for mass production.

Description

technical field

[0001] The invention relates to a detachable frame suitable for a press, in particular to a detachable press frame formed by a movable coupling mechanism. Background technique

[0002] The structure of traditional single-layer or multi-layer plate presses is generally divided into upper-pressure plate presses and lower-pressure plate presses. When the press is in the open state, the opening size of two adjacent platens is usually called the layer spacing. The number of openings in a press is usually called the number of layers of the press. A press with more than 2 layers (including 2 layers) is called a multi-layer press.

[0003] like figure 1 As shown, the upper-pressure plate press is composed of a press frame 1, a workbench 2, a plurality of pressing plates 3, a plurality of hydraulic cylinders 4, a hydraulic system 5 and an electrical control system 6. Multiple groups of hydraulic cylinders 4 are installed on the top of the lower beam 122, the hydra...

Embodiment Construction

[0061] like Figure 7a , 7b As shown, the detachable press frame 1 of the preferred embodiment of the present invention is surrounded by upper and lower beams 121, 122 arranged horizontally and upright columns 11 arranged longitudinally at both ends of the upper and lower beams 121, 122 made. A detachable connection is formed between the beam 12 and the column 11 through a movable connection mechanism.

[0062] like Figure 5a , 5b As shown, the movable coupling mechanism includes a bolt 13 capable of resisting tensile stress and a shear stress washer 15 , a flat washer 16 , a spring washer 17 and a nut 131 which are sequentially connected with it from inside to outside.

[0063] please combine Figure 6a , 6b , the anti-shear stress gasket 15 is center-symmetrical, and has flanges 152 at both longitudinal ends thereof. The anti-shear stress washer 15 also has a central through hole 151 through which the anti-shear stress washer 15 fits with the outer diameter of the bo...
