Problems solved by technology

[0002] The formwork removal of railway cross-web bar prestressed concrete catenary pillars mainly adopts fixed diagonal braces. The angle of the supports should not be too small. If it is too small, it will not be convenient for the wire weaving process, which will cause the steel mold hinges to easily deform during formwork removal. , reduce the service life of the mold, cause the rod to bend, etc.
[0003] At present, the cross-web bar mold support frame is mainly used for the support of the mold hinge, and cannot be used for mold clamping, and the mold hinge is easy to fall suddenly when the mold is removed, which is unsafe, and it will cause great damage to the mold, and it is easy to Make the middle part of the mold bend, causing the rod to bend

Abstract

The invention discloses an automatic die dismounting and mounting device for a railway cross web member type concrete contact net strut, and belongs to mechanical equipment for railway contact net strut production. The automatic die dismounting and mounting device comprises a supporting frame and two sets of die dismounting mechanisms. The two sets of die dismounting mechanisms are the same in structure and are symmetrically arranged in the supporting frame. According to the die dismounting and mounting device, a power piece is mainly used for pushing movable stretching arms, the function of supporting a steel die by any angle is achieved, automatic die assembly can be achieved, the occupied travelling time is shortened, and the production efficiency is improved. Meanwhile, the die pivot angle can be adjusted through the movable stretching arms, and the problems that the damage is caused to the steel die through a fixed type inclined strut support, and in the die dismounting process, due to the too low pivot position, deformation is caused due to sudden falling of a die hinge during die dismounting are solved. The die is protected, the production time is saved, and meanwhile automatic die assembly can be conducted through the device.

Description

technical field [0001] The invention belongs to mechanical equipment for the production of railway catenary pillars, and in particular relates to an automatic disassembly and assembly mold device for railway cross-web bar-type concrete catenary pillars. Background technique [0002] The formwork removal of railway cross-web bar prestressed concrete catenary pillars mainly adopts fixed diagonal braces. The angle of the supports should not be too small. If it is too small, it will not be convenient for the wire weaving process, which will cause the steel mold hinges to easily deform during formwork removal. , Reduce the service life of the mold, cause the rod to bend and so on. [0003] At present, the cross-web bar mold support frame is mainly used for the support of the mold hinge, and cannot be used for mold clamping, and the mold hinge is easy to fall suddenly when the mold is removed, which is unsafe, and it will cause great damage to the mold, and it is easy to Make the...
