Pinch roll mechanism

Abstract

The invention relates to the field of metallurgical mechanical equipment, in particular to a pinch roll mechanism. The pinch roll mechanism at least comprises a rack, an upper oscillating rod, an upper roller driving device, a lower roller driving device, a lower oscillating rod, a lower hydraulic cylinder, an upper hydraulic cylinder and a lifer, and is characterized in that the upper oscillating rod is L-shaped, the length of the upper edge of the upper oscillating rod is larger than the width of the rack, the long edge of the upper oscillating rod is in pin joint with the upper part of the rack through a pin shaft, one end of the upper oscillating rod is fixedly connected with the upper roller driving device, and the other end of the upper oscillating rod is hinged with the upper hydraulic cylinder; the bottom part of the upper hydraulic cylinder is hinged with the lifter, and the lifter is in slide connection with the rack; the lower oscillating rod is in pin joint with the lower part of the rack through a pin shaft, one end of the lower oscillating rod is fixedly connected with the lower roller driving device, the lower oscillating rod is also hinged with the lower hydraulic cylinder, and the bottom part of the lower hydraulic cylinder is fixedly connected with the rack; and the axial lines of the two rollers in the upper roller driving device and the lower roller driving device are located on the same straight line. The pinch roll mechanism provided by the invention can be used for adjusting the openness of the upper roller through the lifter and clamping and loosening the rollers through the upper and lower hydraulic cylinders.

Description

technical field [0001] The invention relates to the field of metallurgical machinery and equipment, and relates to a pinch roller mechanism. Background technique [0002] The pinch roller mechanism is mainly used for clamping and feeding metal strips, tubes, rods and shapes. In the straightening machine device, in order to ensure the reliability and stability of feeding, there are feeding pinch rollers and output pinch rollers respectively installed between the loading and unloading platform and the main machine, and the feeding pinch rollers will feed the material The steel pipe on the stand is sent to the main machine of the straightening machine, and the output pinch roller will send the steel pipe out of the main machine of the straightening machine. The traditional structure is to install several sections of lifting rollers on the loading and unloading table, and drive the rollers through the motor. Rotating to send materials in or out, such a structure is both loaded ...
