Problems solved by technology

Compared with the flying shear, the speed of the static shear unit is low, the production efficiency is low, and the benefit is low
The widespread use of static shears is a great waste of resources
[0004] Chinese invention patent 200610018285.7 flying shears provides a new type of single-crank swinging flying shears, which overcomes the shortcomings of existing flying shears, such as complex structure and movement, high manufacturing cost, and easy failure

Abstract

The invention discloses a double crank frame type flying shear mainly used for a traverse production line which carries out continuous and synchronous cutting to black and non-ferrous metal cold and hot belt materials in the metallurgy. The flying shear drives a reducer and a gear distribution box by the driving of a motor, two crankshafts of a shearing mechanism are driven to drive an upper cutter block and a lower cutter block to carry out planar motion, and the vertical and horizontal planar motion ensures the synchronized motion while completing the shearing motion to the workpiece. The flying shear has the advantages of lighter weight, delicate and simple structure, high strength, flexible and convenient adjustment, easy manufacture and repair, smooth and straight incision, high cutting speed, high cutting precision, and the like.

Description

technical field [0001] The invention discloses a novel double-crank frame-type flying shear, which is mainly used in a cross-cutting production line for continuous and synchronous cutting of black (and non-ferrous) metal hot and cold plates and strips in the metallurgical industry. Background technique [0002] The flying shear refers to a shearing machine that shears the rolled piece transversely and can be cut into a fixed length. It not only needs to meet the requirements of various fixed lengths, but also needs to meet the requirements of shearing accuracy and productivity of the production line. [0003] Since the introduction of modern continuous rolling technology of plate and strip in the 1970s, flying shears have always been one of the important equipment introduced in large iron and steel enterprises in my country. With the rapid development of the national economy, the demand for ferrous (and non-ferrous) metal hot and cold-rolled strips is also increasing, and u...
