Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, the present invention is made up of upper blade 1, screw 3, knife rest 4, base 5 and lower blade 6, wherein the front of knife rest 4 is provided with groove 7, and groove 7 is provided with threaded hole 8; Upper blade 1 is made of Composed of 5-10 blade monomers 2, each blade monomer 2 is fixed in the threaded hole 8 on the groove 7 via a screw 3, and 5-10 blade monomers 2 are closely arranged laterally in the groove 7; The lower blade 6 is affixed to the front upper corner of the base 5, and the distance between the vertical edge of the lower blade 6 and the back of the edge of the blade unit 2 is h 12 2-4mm.

[0022] The blade unit 2 of the upper blade 1 is driven by the hydraulic device of the shearing machine, and can move up and down and laterally.

[0023] Such as figure 2 and image 3 As shown, the tool holder 4 is lon...

Abstract

The invention discloses a separating type shearing knife, and belongs to the technical field of metal cutting. A groove 7 is formed in the front surface of a knife rest, and a threaded hole is formed in the groove; an upper blade consists of 5-10 blade units, each blade unit is fixedly connected to the threaded hole in the groove through a bolt, and the 5-10 blade units are transversely and tightly arranged in the groove; a lower blade is fixedly connected to a front upper corner of the base; and a distance h12 between a perpendicular cutting edge of the lower blade and the back surface of the cutting edge of each blade unit is 2-4mm. According to the separating type shearing knife disclosed by the invention, the tip parts of the blade units are manufactured to be triangular, and the knife tips can effectively increase shearing penetrating capacity, so that the shearing resistance is reduced, and the efficiency is improved; meanwhile, each position of the knife body during shearing is different in stress impact, so that the invalid blade unit can be independently replaced when local blade unit is invalid, and therefore, the cost is reduced; and meanwhile, the combined type upper blade carries out transverse shearing motion, so that the roughness of a sheared surface of a sheared material is reduced, and processing precision is improved.

Description

technical field [0001] The invention belongs to the technical field of metal cutting, and in particular relates to a separate shearing knife. Background technique [0002] The shearing machine is the key equipment in the continuous rolling production line of the modern rolling mill. It is usually used for cutting the head, tail and cut-to-length of billets, slabs, steel plates and some strip steel products. In the processing of the steel industry, shearing machines are used more and more widely. From small crocodile shears with a shearing force of tens of thousands of cattle to medium and large portal shears with a shearing force of tens of thousands of cattle, there are various models and varieties. Mechanical cutting of various bars, bundles, components and pressed sheet materials to obtain steel materials of a certain size. [0003] In the shearing machine, the blade is the key component to achieve the final cutting purpose. Its quality and life will directly affect the ...
