Cutting-to-length system of hot-rolled round steel

Abstract

The invention discloses a cutting-to-length system of hot-rolled round steel and belongs to the technical field of mechanical engineering. The cutting-to-length system comprises a trolley, a cutting rack, a carrier unit and a guide rail; the cutting rack is hinged to one end of the trolley; the other end of the trolley is provided with an automatic clamping mechanism and a manual carrying structure; the automatic clamping mechanism comprises a first clamp plate and a second clamp plate; the carrier unit is disposed in a discharging direction of the automatic clamping mechanism and comprises a conveying carrier roller support, a carrier roller base and carrier rollers; the carrier roller base is provided with a photoelectric sensor; the cutting rack comprises a cutting saw rotor base, a drive motor and a transmission device; an opening of the cutting saw rotor base is provided with a cutting saw; a second hydraulic cylinder is fixed on the guide rail; the moving end of the second hydraulic cylinder is fixedly connected with the trolley. The cutting-to-length system has the advantages that cutting-to-length is automatically controlled through the combination of the hydraulic cylinders and the trolley, the length is fixed during moving, the moving range is narrow, the speed is high, length precision is high, and operating efficiency of a shearing machine is evidently improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and more specifically relates to a cutting-to-length system for hot-rolled round steel. Background technique [0002] At present, the existing cut-to-length methods for hot-rolled round steel with specifications of φ12mm~φ65mm at home and abroad mainly include fixed-length stop-shear and fixed-length flying shear. The efficiency is low. For large-scale rolling equipment, frequent start and stop will affect the life of the equipment; currently, the fixed-length flying shears generally use stopper positioning flying shears, servo motors and servo automatic follow-up flying shears. The control of stopper positioning flying shears is relatively simple. It is determined by the profile The shearing table is driven by itself to follow the flying shears, but its disadvantages are frequent block adjustment, complex structure, poor product adaptability, and low production efficiency; the se...

[0002] At present, the existing cut-to-length methods for hot-rolled round steel with specifications of φ12mm~φ65mm at home and abroad mainly include fixed-length stop shearing and fixed-length flying shearing. The control of ruler stop and shear is simple, and the precision of length is high. The disadvantage is that the production efficiency is low. For large-scale rolling equipment, frequent start and stop will affect the life of the equipment; currently, the fixed-length flying shears generally use stopper positioning flying shears and servo motors and servo automatic follow-up Flying shears, stopper positioning Flying shears control is relatively simple, it drives the cutting table to follow the flying shears by the profile itself, its disadvantages are frequent stopper adjustments, complex structure, poor product adaptability, and low production efficiency; servo automatically follows the flying shears , the structure of the whole machine is simple, the production line is smooth, and its disadvantages are complex control, high equipment cost, and the following process is easily affected by the external environment

Especially for the cut-to-length hot-rolled round steel with a specification of φ12mm~φ65mm, due to its large diameter, too fast cutting will cause a lot of burrs on the tail of the round steel, and too slow cutting will affect production efficiency, and the required cutting length To be precise, therefore, higher requirements are put forward for the cut-to-length control
