Model RF300 Highway Two-Wave Cold Bending Forming Automatic Production Line For Guardrail Use

Product Introduction:

Highway guard rails forming line highway protective guarding production line guardrails forming line Can achieve the original single sheet of multi-process, uninterrupted production, set uncoiling, levelling, punching, forming, shearing in one continuous production, so that the product appearance standard, punching consistent installation is easy. The production line has high production speed, on-line punching and continuous moulding production, easy to operate and use less labour.

Product configuration:

Note: The board type drawing shall be subject to the drawing finally signed and confirmed by the buyer and seller.

Production process:

The production line is operated according to the following process flow: Uncoiling → Loop (storage) → Servo leveling feeding → 315T punching (cutting) + punching and strengthening press → cold bending → discharging

Unit configuration and purpose

Uncoiler - 1 set

Unwinding: The machine is in single-support mode. The motor drives the uncoiler shaft to release the coil, and the hydraulic power drives the tensioning device of the uncoiler shaft to fix the coil on the uncoiler shaft. The tensioning structure is wedge-type, and the working state is stable and reliable.

The uncoiler is an automatic uncoiler. When the coil is installed on the uncoiler shaft, the uncoiler shaft rotates actively during the actual operation of the whole line, and its traction power comes from the uncoiler motor. The uncoiler can automatically release the coil according to the running speed of the whole line. To ensure the actual operation safety of the uncoiler, the uncoiler is equipped with a pneumatic brake device.
The uncoiler also contains 4 baffles and a pressing arm to prevent the coil from loosening during the unwinding process and ensure the safety of the operator.

Storage (silo) device - 2 sets

Purpose: Used to buffer the speed mismatch between unwinding leveling and punching machine and punching machine and roll bending forming machine, and correct deviation. It makes the whole line run smoothly and completely.

Structure: The storage device consists of two parts: arc rollers and supporting device. There are four groups of arc rollers, which are placed on both sides of two storage bins. They are composed of arc frames and a group of flexible rollers. The surface of the rollers is hard chrome plated. A photoelectric switch is installed in the pit of the discharge bin to control the position of the material roll entering the pit, so that the speed of each working part can be perfectly matched.

Servo leveler feeder - 1 set

Purpose: Feed the sheet material according to the actual step length required for punching. Multiple sets of feeding parameters can be set at one time, which is convenient and fast. The feeding accuracy is accurate without cumulative tolerance.

It adopts 5-roller leveling (2 rollers on the upper layer, 3 rollers on the lower layer, screw adjustment), 1 pair of guide rollers, pneumatic clamping of feeding rollers, frequency conversion speed regulation, and electrical switch control. The front of the leveling machine is also equipped with a telescopic shovel head and a pressing device to ensure that the raw material roll enters the leveling machine smoothly and safely.
Structure: It consists of a frame, a clamping system, and a servo drive system.
