Bending forming die tool for bus roof through beam

Abstract

The invention discloses a bending forming die tool for a bus roof through beam. The tool comprises an upper die and a lower die which are mutually matched for work, wherein each of the upper die and the lower die comprises a bottom plate, and two rows of opposite bolts are arranged on the bottom plate; a row of upper reinforcing plates and a row of lower reinforcing plates are welded on the bottom plates of the upper die and the lower die respectively; an upper die arc plate is welded on each of two sides of the upper reinforcing plates, each of two ends of one upper die arc plate is connected with the corresponding end of the other upper die arc plate through an upper baffle plate, and the upper die arc plates and the upper ends of the upper reinforcing plates are spliced through an upper arc plate; a lower die arc plate is welded on each of two sides of the lower reinforcing plates, each of two ends of the one lower die arc plate is connected with the corresponding end of the other lower die arc plate through a lower baffle plate, and the lower baffle plates and the upper baffle plates are oppositely arranged; the lower die arc plates and the upper ends of the lower reinforcing plates are spliced through a lower arc plate. The die tool has sufficient strength and rigidity, is simple in structure and is light; under the premise that the strength and the rigidity are guaranteed, the structure is simple and compact as far as possible, the size is small, the mass is light, and workpiece loading and unloading are facilitated.

Description

technical field [0001] The invention relates to a tooling of a bending forming die for a curved roof beam of a bus, in particular to a tooling for a bending forming die of a large roof penetrating beam of a bus. Background technique [0002] At present, there is no pre-bending forming mold for the production of large roof curved beams of passenger cars, and straight materials have been used for bending, which is inefficient and easily leads to distortion of the curved beams; and due to the continuous increase in variety and output, it has been unable to meet production needs. Cause production efficiency to be low, this problem has not had effective solution all the time. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention designs a kind of tooling of the bus big roof penetrating beam bending forming mold according to the requirement of bending pipe radian. It is to support the mold body and position it on the hydraulic ...
