Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] figure 1 It is a schematic diagram of the shearing principle of the present invention. Such as figure 1 As shown, let v 1 is the moving direction velocity of the sheared plate 1, v 2 is the speed of the scissors moving along the x-axis, then: v r =-v 1 , v e =v 2 ,Depend on: v → a = v → e + v → r , Obtain the absolute moving speed of the knife on the plate

[0026] Because the moving direction and speed of the sheared plate 1 are constant, that is, v r is a fixed value, then:

[0027] (1) When the speed of the tool moving along the x-axis is constant, that is, v 2 When it is a fixed value, v a with v r The i...

Abstract

The present invention discloses a kind of variable width disk shearer. It includes shears shaft box body, worm gear box body and guideway. On the top portion of said worm gear box body the shears box body is connected, and the bottom portion of said worm gear box body is connected on the guideway. Said invention also provides its working principle and its concrete operation method.

Description

technical field [0001] The invention relates to a shearing machine, in particular to a disc shearing machine capable of variable-width shearing of plates. Background technique [0002] Among existing shearing machines, shearing machines are usually divided into the following four categories according to the shape and configuration of the blades and the condition of the plate: 1) Parallel blade shearing machines. The two blades of this shearing machine are parallel to each other, and are usually used for transverse thermal shearing of blooms (billets, slabs) and other steel billets with square and rectangular cross-sections. 2) Inclined blade shears. One of the two blades of this shear is at an angle relative to the other. This type of shearing machine is commonly used for cold shearing and hot shearing of steel plates, strips, etc. 3) Disc shearing machine. The two blades of this shearing machine are made into a disc shape, and this type of shearing machine is used to lo...
