Guardrail roll forming machine is a kind of equipment used to manufacture guardrails. It is usually used to produce guardrails made of metal or plastic materials, and can process materials into guardrail products of different shapes and sizes according to design requirements. This equipment is usually used in industrial production and can efficiently produce a large number of guardrail products. Using guardrail forming machine can improve production efficiency and ensure consistent product quality.
The working principle of guardrail roll forming machine mainly includes the following steps:
1. Loading
Place the raw materials (such as steel strips, aluminum plates, etc.) on the feeding device of the guardrail forming machine. The feeding device usually adopts an unwinder or unwinding rack, which can smoothly unfold the rolled raw materials and convey them to the subsequent processing links.
2. Leveling
The raw materials after unfolding may be uneven and need to be leveled by a leveling device. The leveling device is generally composed of multiple rollers arranged up and down. Through the extrusion and stretching action of the rollers, the bending, wave and other deformations of the raw materials are eliminated, so that the surface flatness meets the requirements of subsequent processing.
3. Punching (optional)
If the guardrail needs to be punched, such as for installation, fixing or decoration, the leveled raw materials will enter the punching link. The punching device punches the raw materials according to the preset hole type and position. The punching die can be replaced according to different hole type requirements to meet the punching needs of various guardrails.
4. Forming
The raw materials that have been leveled or punched (if there is such a step) enter the forming area. The forming area is usually composed of one or more groups of rollers, which are designed and arranged according to the shape and size of the guardrail. The raw materials gradually form the shape of the guardrail under the extrusion and bending of the rollers. During the forming process, it is necessary to control the pressure, speed and other parameters of the rollers to ensure the forming quality and dimensional accuracy of the guardrail.
5. Welding (optional)
For some metal guardrails, welding may be required. If the guardrail forming machine is equipped with a welding device, the guardrail can be welded during the forming process. The welding method can be selected according to the material and requirements of the guardrail, such as argon arc welding, resistance welding, etc. During the welding process, the welding quality, such as the strength and sealing of the weld, should be ensured to ensure the performance of the guardrail.
6. Cutting to length
When the formed guardrail reaches the set length, the cutting device will cut it off. The cutting device can be hydraulically cut off, mechanically cut off, etc. The cutting accuracy and speed need to match the overall production efficiency of the forming machine. For some guardrail forming machines that require continuous production, online cutting may be adopted, that is, cutting is performed during the continuous conveying of the guardrail to improve production efficiency.
7. Discharging
The cut guardrail is output from the forming machine through the discharging device. The discharging device is usually composed of a conveyor belt, a discharging roller, etc., which can smoothly convey the guardrail to the finished product stacking area. During the discharging process, care should be taken to avoid collision and friction between the guardrails to avoid damaging the surface quality of the guardrail.
8. Control system
The entire working process of the guardrail roll forming machine is monitored and adjusted by the control system. The control system usually adopts PLC (Programmable Logic Controller) or industrial computer, which can realize the functions of automatic control, parameter setting, fault diagnosis and other functions of the equipment. Operators can easily adjust the operating parameters of the equipment and monitor the operating status of the equipment through the human-machine interface of the control system to ensure the stable operation of the equipment and the quality of the products.
