To reduce the scratch rate of the guardrail surface of the highway guardrail forming machine, we can start with equipment optimization, process improvement, and operation specifications. The specific measures are as follows:
1. Optimization of molds and rollers:
Use rollers with chrome plating or spray-coated wear-resistant coating to reduce the friction coefficient; regularly check the wear of the roller surface, and repair or replace the scratches in time to ensure that the surface roughness of the roller is Ra≤0.8μm.
2. Material conveying protection:
Install guide rollers between the unloading rack and the main machine feed port, and wrap them with polyurethane or rubber materials to reduce direct contact between materials and metal parts; use automatic deviation correction devices to avoid material deviation and scratching equipment.
3. Process parameter adjustment:
Set a reasonable rolling speed according to the material characteristics to avoid excessive speed causing severe friction between the material and the mold; optimize the forming passes, reduce unnecessary bending times, and reduce the risk of surface damage.
4. Lubrication and cleaning management:
Lubricate the mold and transmission parts regularly, choose low-residue, non-corrosive lubricants to prevent oil stains from contaminating the guardrail surface; clean the iron filings, dust, and other impurities on the equipment table and rollers before production.
5. Employee operation specifications:
Train employees to standardize loading and mold changing operations to avoid rough loading and unloading; require employees to wear gloves and use soft tools to prevent human scratches; conduct regular inspections during production and handle abnormalities in a timely manner.
6. Receiving and storage protection:
Install a buffer device at the receiving end to prevent the guardrail from colliding with the receiving rack; use rubber pads or wooden partitions to separate the finished products when stacking to prevent mutual friction; wrap them with wrapping film or soft packaging materials during transportation.
