Problems solved by technology

[0003] At present, the demand for corrugated steel webs is increasing, and the specifications of plate thickness are also increasing day by day. Various models are used, but the molding dies are not adjusted according to the plate thickness or model, which in turn leads to the processing of corrugated steel webs. In the process, there are shortcomings such as low production efficiency and poor precision of the finished product, which brings many problems to the standardized production of corrugated steel webs

Abstract

The invention discloses a bending radius-adjustable corrugated steel web mould pressing die comprising a punching machine head and a base, wherein the punching machine head is connected with a top seat; the base is arranged below the top seat corresponding to the punching machine head; top seat pressing plates are fixed on both sides of the punching machine head on the top seat by bolts; the tail of the punching machine head is welded with the top seat to be fixed and the head is connected with an upper stamping die; the base is provided with a lower stamping die. By adopting the bending radius-adjustable corrugated steel web mould pressing die to carry out mould pressing on a steel plate, groove moulds of the stamping dies can be quickly replaced according to needs, and corrugated steel webs with different thickness ranges can be processed to meet market requirements of products. The stamping dies are arranged in a separated manner, so as to meet the mould pressing requirements of different types of steel plates within the thickness range of (10mm-30mm), the device cost is reduced, operation steps are simplified, the accuracy of manufacture of the products is improved, the production efficiency is improved, large-scale production is facilitated, and competitiveness of business market is strengthened.

Description

technical field [0001] The invention relates to the field of forming devices for corrugated steel webs, in particular to a molding die for corrugated steel webs with adjustable bending radius. Background technique [0002] Prestressed concrete bridges with corrugated steel webs have a series of advantages such as good seismic performance, simple construction, and good economy. With the development of theory and practical applications, prestressed concrete box girder bridges with corrugated steel webs are more and more popular among bridge engineers. The domestic application is developing rapidly, and it has been used in simply supported beams, continuous beams, rigid frame bridges, cable-stayed bridges and other bridge types, and the maximum span of continuous beams has reached 160m. As the main component of the corrugated steel web bridge, the thickness of the steel plate has expanded from 8 to 12mm in early 2000 to about 30mm now. Different types of corrugated steel webs ...
