Multidirectional load bearing prestressed wire winding pre-tightening frame

Abstract

The invention relates to a multidirectional load bearing prestressed wire winding pre-tightening frame, belonging to the technical field of heavy type pressure processing equipment. The pre-tightening frame at least comprises three arc beams which are the same in pressing counter force quantity and are in opposite directions as well as at least three straight beams, the arc beams and the straightbeams are arranged alternately, the outline of the straight beam is tangent with the outer arc outline of two adjacent arc beams, so as to form a frame, and the periphery outline of the frame is wound with prestressed wire. In the invention, structure composed of arc beam and straight beam is reasonably arranged on the periphery outline of the load bearing frame, so that prestressed wire is woundand pre-tightening forces in multiple directions are produced, so as to balance multidirectional pressing counter force, thus the frame can bear multidirectional loads without a tensioning construction member provided with through structure, thereby avoiding structural interference problem.

Description

technical field [0001] The invention belongs to the bearing structure used in the field of heavy pressure processing equipment, in particular to a prestressed steel wire winding frame capable of bearing multidirectional loads. Background technique [0002] The frame capable of bearing multi-directional loads referred to in the present invention refers to heavy-duty pressure processing equipment, especially equipment that applies pressure to workpieces simultaneously or step by step from more than two directions. [0003] Pressure processing equipment is to complete the processing by acting on the workpiece or mold with a certain pressing force, such as various forging equipment, stamping equipment, rolling equipment and die-casting equipment. Commonly used pressure processing equipment has two parallel and opposite pressing forces acting at the same time, one of which is usually actively applied (such as: using a hydraulic cylinder, crank linkage or forging hammer, etc.), wh...

Problems solved by technology

Because the arc angle of the column section is small, and the arc is distributed on the entire column, the pressure of the steel wire on the contour is small and dispersed, so this kind of rack does not have the predictability of producing multiple directions, especially perpendicular directions.
