Bending and compression combination-type corrugated steel web formation device

Abstract

The invention relates to a corrugated steel web formation device, and discloses a bending and compression combination-type corrugated steel web formation device, which comprises a punching mechanism and a bearing mechanism which is arranged below the punching mechanism, wherein the punching mechanism is provided with a compression bracket and two bending brackets which are arranged at the left and the right sides of the compression bracket, the compression bracket is provided with a force application projection, a male mould is embedded on the force application projection, the bearing mechanism comprises a lower mould frame and a female mould which is arranged on the lower mould frame, the lower mould frame is provided with a bearing groove which is matched with the female mould, the female mould is embedded inside the bearing groove, a steel web to be processed is arranged between the punching mechanism and the bearing mechanism, and the lower bottom part of the bending mechanism is provided with an arc wing plate. The device integrates the compression and the bending. Less than two points on a uniform cross section are stressed when forming the steel web, so the crackles which are formed because the formation surface is easy to be stretched and become thin can be prevented; and moreover, the formation power is small, and the rebound difference is small.

Description

technical field [0001] The invention relates to a corrugated steel web forming device, in particular to a bending and molding hybrid corrugated steel web forming device. Background technique [0002] In the traditional corrugated steel web bending forming technology, the inner mold and the outer mold only use molds with a certain radius and they coincide with each other. During the bending process, there are large power requirements for corrugated steel web forming and large differences in rebound. , Low molding efficiency, poor precision of molded products and other defects. For example, the patent number applied by Tiger Hengsan Co., Ltd. is: 01803104.8 invention patent, the application date is October 12, 2001, the announcement number is CN1392807A, and the name is metal bending device. The convex curved surface of the mold is mounted on the two concave curved surfaces provided on the surface of the support in a rotatable and slidable manner. At the same time, one end o...

Problems solved by technology

[0003] The present invention aims at the traditional corrugated steel web bending forming technology, in the bending process, there is a large force on the corrugated steel web bending surface It is easy to be stretched and thinned to form cracks, and the forming power requirements are large, the rebound difference is large, the forming efficiency is low, and the precision of the formed product is poor. A special bending and pressing hybrid corrugated steel web forming equipment is provided. It can be applied to the forming and manufacturing of various corrugated steel webs of highway bridges, railway bridges, shear walls of reinforced concrete buildings and reinforced concrete support projects of tunnels, and the manufacturing accuracy is easy to control, and the power configuration of the press is small
