Description

Technical Field

[0001] The utility model relates to the technical field of corrugated guardrails, in particular to a stamping and forming device for processing corrugated guardrails. Background Art

[0002] The corrugated guardrail is a combined corrugated plate movable steel guardrail used at the opening of the central dividing strip of the highway. The guardrail consists of two corrugated steel guardrail plates and two columns fixedly clamped between the two corrugated steel guardrail plates. The two columns are fixedly clamped between the two corrugated steel guardrail plates. When the highway is in normal operation, the guardrail can be easily inserted into the pre-set plug-in holes at the opening using the plug-in columns, which plays an isolation and protection role. At the same time, it echoes the guardrail belt on the outside of the highway, which is neat, uniform, and beautiful. When a vehicle collides with it, the corrugated steel guardrail plate has good collision resistance and energy absorption, so it is not easy to be destroyed, and at the same time it can provide good protection for the vehicle and the driver and passengers.

[0003] When the corrugated guardrail is stamped, the width of the corrugated guardrail is inconsistent. When the corrugated guardrail is stamped, the mold stamping pressure is large. During the pressing process, the corrugated guardrail material shakes and deviates during the stamping process, which can easily lead to poor forming effect of the corrugated guardrail and the corrugated shape is not continuous enough, affecting subsequent use.
