Embodiment Construction

[0020] The technical solution of the present invention will be further described below in conjunction with a preferred embodiment and the accompanying drawings.

[0021] In this embodiment, pressure rollers are added in front of the existing plate combined shearing mechanism (hereinafter referred to as "combined shear", including double-sided shears and split shears) to participate in the shearing of combined shears, thereby preventing the steel plate from drifting and drifting.

[0022] More specifically, see figure 2 In this embodiment, the plate combination shearing mechanism includes double-sided shears and split shears, and at least one set of pressing rollers 4 is provided before the entrance of the double-sided shears.

[0023] The aforementioned pinch rolls include an entry-side pinch roll and an exit-side pinch roll arranged in sequence along the feeding direction of the steel plate (as indicated by the arrow).

[0024] The aforementioned entry-side pinch rollers in...

Abstract

The invention discloses a combined plate shearing mechanism improved structure and a combined plate shearing processing method. The combined plate shearing mechanism improved structure comprises a double side trim shear, a splitting shear, and more than one group of press rolls arranged in front of an entrance of the double side trim shear at least. The combined plate shearing processing method comprises the following steps: a combined shearing mechanism is provided and comprises the double side trim shear and the splitting shear, and the more than one group of press rolls arranged in front of the entrance of the double side trim shear at least; during the process of steel plate shearing, a steel plate is clamped synchronously through the more than one group of press rolls and more than one group of pinch rolls in the combined shearing mechanism to be prevented from deflection due to shift, and the steel plate is sheared by the combined shearing mechanism. The combined plate shearing mechanism improved structure and the combined plate shearing processing method are simple and easy to implement, can solve the deflection problem during the problem of steel plate shearing, improve the steel plate shearing quality, and reduce the loss due to too large allowance of the steel plate, thereby producing remarkable economic benefits; and meanwhile, the produced steel plate does not need to be subjected to off-line polishing, so that the labor intensity of field staff and the field potential safety hazards are reduced.

Description

technical field [0001] The invention relates to a medium-thick plate shearing device and a shearing method in the field of iron and steel metallurgical machinery, in particular to an improved designed plate shearing mechanism and plate shearing method. Background technique [0002] refer to Figure 1-Figure 2 At present, in the finishing and shearing process of the medium and heavy plate factory, when the steel plate enters the shearing machine, it is generally clamped by the pinch rollers on the fixed side and the moving side to complete the feeding and shearing of the steel plate. Due to the differences in equipment , For example, the wear degree of the pinch roller surface is different, the horizontal direction and vertical direction of the pinch roller are different, the clamping force of the fixed side and the moving side is different, and manpower cannot adjust it accurately, which will easily lead to the deviation of the steel plate (Generally between 20mm and 30mm), ...
