Uncoiler with adjustable head radius

Abstract

The invention relates to an uncoiling machine capable of adjusting the radius of a coil head. The uncoiling machine is characterized by comprising a motor, a speed reduction box and an installing bracket, wherein the power output end of the motor is connected with the input end of the speed reduction box, an output shaft of the speed reduction box is connected with a coil head part, a pressing device and an inverted roll-bending device are arranged on the installing bracket; the coil head part comprises an uncoiling main shaft, an uncoiling pull rod shaft is connected into a center hole of the uncoiling main shaft in an inserting manner, a coiling drum part is arranged on the uncoiling main shaft, one end of the uncoiling pull rod shaft is connected with a cross plate, the other end of the uncoiling pull rod shaft is connected with a piston rod of an uncoiling oil cylinder; the coiling part comprises a fan-shaped plate arranged outside the uncoiling main shaft, a sliding base connected with the cross plate is arranged outside the uncoiling main shaft and consists of a plurality of inclined surfaces which are arranged in parallel; inclined surfaces matched with the inclined surfaces on the sliding base in a one-to-one manner are arranged on the inner surface of the fan-shaped plate, and inclined surface copper sliding plates are respectively arranged on the inclined surfaces of the inner surface of the fan-shaped plate. The uncoiling machine is capable of preventing the steel coil head from being bent in an arc manner, and the radius of the coil head is adjustable.

Description

technical field [0001] The invention relates to an uncoiler with adjustable coil head radius, in particular to an uncoiler for uncoiling steel coils, and belongs to the technical field of continuous processing equipment for steel strips. Background technique [0002] In the steel strip continuous processing production line in the steel industry, an uncoiler is generally used for uncoiling the steel strip. However, in the prior art, the uncoiler is prone to lead arc bending for a while, which leaves hidden dangers for the subsequent operation of the process, and may easily cause the steel strip to be jammed. low. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an uncoiler with adjustable coil head radius to ensure smooth uncoiling and avoid arc-shaped bending of the steel coil head; and the coil head radius is adjustable. [0004] According to the technical solution provided by the presen...
