Hydraulic decoiler

1. Structure

This machine is a single-head cantilever hydraulic expansion and contraction decoiler, which is composed of a main shaft part and a transmission part.

1. The main shaft part is the core part of the machine. Its four blocks are connected to the slidingsleeve through T-shaped inclined blocks and are simultaneously sleeved on the hollow main shaft. The core is connected to the sliding sleeve. The oil cylinder controls the movement of the mandrel to achieve four The fan block expands and contracts at the same time. When the fan block is contracted, it is beneficial to roll up, and when the fan block is opened, the steel coil is tightened to complete the unwinding.

1. The pressure roller part is located behind the uncoiler. The pressure arm can drive the cantilever to press down and pick up under the control of the oil cylinder. When feeding, press down the cantilever pressure roller to press the steel coil, which can prevent loose coils and facilitatefeeding.
2. The transmission part is located outside the frame, and the main shaft of the uncoiler is driven to rotate by the motor and the reducer through the gear, which can also realize the positive and negative uncoil and rewind.

Hydraulic Up-Coil cart

1. Structure

It is mainly composed of a car disc, a cylinder seat, an oil cylinder and walking system. When working, put the steel plate on the top of the oil cylinder at the position of the trolley tray. The oil cylinder lifts the steel plate to the height of the decoiler. The motor started to move to the center of the decoiler. The decoiler tightens the steel coil and the loading car rolls along the track. Return to the feeding area.
