Double-acceleration synchronous tracking fixed-length flying shear

Abstract

A double-acceleration synchronous tracking fixed-length flying shear is composed of a first servo motor, a second servo motor, a first sliding support, a first lead screw, a second lead screw, a second sliding support, a first hydraulic cylinder, a first shear module, a second hydraulic cylinder, a second shear module, a first guide rail, a second guide rail, a third guide rail, a fourth guide rail, a third hydraulic cylinder, a first rotary encoder, a control unit and a second rotary encoder. By the adoption of the hydraulic driving method for quick acceleration and the servo motor driving lead screw method for accurate positioning, responding speed and length setting accuracy can be effectively improved. Meanwhile, due to the adoption of a hydraulic driving shear device, the size of the whole machine can be effectively reduced. By the adoption of the flying shear, fixed-length shearing of workpieces can be achieved without stopping the machine on the whole production line, working efficiency can be improved effectively, and cost can be reduced effectively.

Description

technical field [0001] The invention relates to a flying shear, in particular to a dual-acceleration synchronous tracking fixed-length flying shear. Background technique [0002] Existing sheet metal shearing equipment is generally divided into stop shear and flying shear. Stop shear means that the material to be cut needs to be stopped, and then the scissors part is cut; flying shear means that the material to be cut does not need to stop, while the scissors Part can be cut. [0003] The advantage of stopping shearing is that the precision is high but the efficiency is low, and the flying shear can cut the plate without stopping the plate when cutting the plate, which greatly improves the production efficiency. [0004] At present, flying shears are basically crank-link flying shears or rotary flying shears. The mechanism is relatively complicated and the equipment is bulky. Not only the cost is high, but also the cutting accuracy is relatively low, which cannot meet the n...

AI Technical Summary

Problems solved by technology

[0004] At present, flying shears are basically crank-link flying shears or rotary flying shears. The mechanism is relatively complicated and the equipment is bulky. Not only the cost is high, but also the cutting accuracy is relatively low, which cannot meet the needs of production.

At the same time, the synchronization device of the flying shear machine mostly uses the servo motor to drive the screw device to accelerate, it is difficult to have both speed and sizing accuracy at the same time, and the cost of the servo motor with larger power is higher
