How the coiler works
The hot rolled strip coiler adopts floating frame to ensure that the end surface of the strip is neat and the quality is guaranteed, which is monitored by the strip edge control device, so that the stand can track the strip and prevent the strip coiling from producing a string layer, which is controlled in the minimum range.
The stand is mainly composed of a floating base and a base. The piston rod is connected with the floating base. The piston moves in both directions and the stroke is + / -150 mm, while the hydraulic oil of the floating cylinder is supplied and controlled by the hydraulic station of the separate strip edge control device. The sliding way of floating base adopts sliding plate type, which can adjust the gap between the upper and lower sliding plates with the top wire, and can be guaranteed during assembly or by adding gasket under the pressure plate. The sliding surface of the floating base shall be lubricated with grease.
The expansion and contraction of the drum is connected with the expansion diameter and Angle wedge of the clamp through the tie bar and push block in the middle of the spindle. The diameter of expansion and contraction can be realized by the radial movement of the four fan-shaped blocks. According to the position in the assembly drawing, the expansion diameter will be generated when the hydraulic cylinder piston moves to the left. It shrinks as it moves to the right. The clamping port is located at the connection of the lower two fan-shaped pieces. The hole is open when reducing the diameter, which can feed the steel. The hydraulic cylinder device is fixed on the reducer, and the rotary of the drum is driven by the frequency conversion alternating current motor through the reducer.
The push plate device is used to remove the coil from the reel. The push plate device is provided with two guide rods, which are fixed on the upper box of the reducer with sliding bearing seat. The push plate device moves forward and backward with hydraulic cylinder to operate.
