Detachable press frame

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...

Problems solved by technology

However, the positioning plate 14 needs to be installed by welding, and the heat of welding will deform the column, which directly affects the precision of the press and the deviation of the thickness of the pressed product.
