Problems solved by technology

This kind of clapboard iron parts needs to use acetylene gas to cut the seam of the steel plate first, then bend it, and then weld it after bending, which not only wastes oxygen acetylene and welding electrodes, but also requires multiple processes to complete, which is inefficient and a serious waste of resources.

Abstract

The invention overcomes the defect of incapable realization of high-efficiency mass production in the production process of bridge partitions and provides a mold for bending iron bridge partitions. The mold has the advantages of simple structure and favorable operational performance and comprises a frame, wherein the frame consists of a bottom plate and a portal frame, the bottom plate is used asa workbench, and the portal frame is connected with the bottom plate into a whole; a lifting jack reversely fixed on the portal frame is arranged in the portal frame; a detachable upper mold is arranged on a hydrocylinder of the lifting jack; and a lower mold matched with the upper mold is arranged on the bottom plate. The invention can enable the partition to be molded by one step so as to enhance the working efficiency and the performance of the partition and improve the appearance of the partition; and when processing the mold, many working procedures are omitted so as to save the resources.

Description

technical field [0001] The invention relates to a bending mold machine used in the manufacturing process of clapboard iron parts in the production process of prestressed T-shaped bridges, in particular to a mold machine for bending iron clapboards of bridges which can form processed workpieces at one time. Background technique [0002] At present, as the process of processing iron parts for bridge clapboards, the general processing flow is: use a semi-automatic gas cutting machine to cut the required steel plates according to the size requirements, drill fixing holes on the drill press, and then draw the bending position marking line with a stone pen, along the scribed line Use acetylene gas to cut a seam, keep 1cm at both ends without cutting, and then use acetylene gas to bake the two ends of the steel plate without breaking, use a special wrench to bend the iron parts of the partition to a fixed angle, and then weld on the curved surface For the anti-deformation steel bar...
