Manufacturing method of cold roll forming for waveform beam guardrail plate

Abstract

The invention discloses a manufacturing method of cold roll forming for a waveform beam guardrail plate, which is manufactured by devices in sequence: a rolling plate fixing bracket, a cutting edge perforating device, a cold bending machine group, a flying saw, a material receiving plateform, and the like. The method comprises the following steps: a material slowing geosyncline is formed in a position between the rolling plate fixing bracket and the cold bending machine group and below the ground for reducing feeding resistance of the cold bending machine group and facilating accurate positioning in a steel plate feeding; and energy accumulation rings of circular steel pipes on two sides are distributed on two sides of a central axis of the cold bending machine group and integrally formed with a guardrail plate body contimiously, therefore, the rigidity of a product is greatly inproved, and the mechanical properties of a section is guaranteed to be fully played. The manufacturing technique has excellent system formation effect for controlling cold bending energy storage quality of the waveform beam guardrail plate, improving mouth closing accuracy and connection strength of inner circles of the energy accumulation rings, and the like. The manufacturing method has reasonable structure, convenience in operation, and high working efficiency.

Description

technical field [0001] The invention relates to the manufacture of anti-collision facilities for vehicles suitable for highways and bridges, in particular to a method for manufacturing single-wave beam guardrails. Background technique [0002] With the rapid development of highway construction in our country, traffic safety is facing a severe situation. As a safety facility, single beam steel guardrail plays an important role in protecting the traffic safety of highways and bridges. [0003] The single-wave beam steel guardrail is an important safety protection facility, which has an ideal buffer function when blocking out-of-control vehicles. The single-wave beam guardrail board, as the main component of the single-wave beam steel guardrail, requires proper manufacturing methods to meet the design requirements. Manufacturing equipment If it is not precise, the designed anti-collision level and cushioning capacity cannot be achieved. At the same time, as anti-collision guar...
