1. Cutting and cutting
Before cutting, first adjust the slope of the cutting machine to match the required slitting ruler. Determine the position of the steel plate to ensure the maximum size of the remaining material so that the remaining material can be used. The length dimension is guaranteed by Kaiping, the wide bottom dimension is required to be ≤±2mm, and the blanking dimension tolerance of the high rod is to be positive for each section of the rod; generally: 0-2m. Take the minus tolerance for the small head, and after the -2-0mm size is adjusted, it is completed by the cutting machine and the automatic cutting machine. In terms of equipment: When cutting materials, check the operation of rolling shear equipment, remove debris on the track, and keep the equipment in good operating condition.
2. Rivet
The requirements for aluminum troughs are not very high. As long as the materials are selected according to the drawings of the design institute, there will be no problems. However, special attention must be paid to the production, because the aluminum trough is the connector of the sign and the rod. If the aluminum trough and the aluminum plate are not fixed If it is strong, it will cause major traffic accidents.
3. Attach reflective film
The choice of reflective film has a great relationship with traffic safety. Generally, the higher the road level, the higher the level of reflective film, such as highways and first-class highways, generally use second-level and above-level reflective film, because Highways with high grades generally drive faster. If a low grade reflective film is used, the reflective brightness is not enough, and the driver cannot see the content on the sign in time, or the driver pays attention to the sign because the reflective brightness is not enough. Easy to cause traffic accidents.
