Problems solved by technology

Although this adjustment device and method are more flexible in operation and more convenient in adjustment, there are still the following defects: first, since the main shaft still has gap adjustment parts such as eccentric sleeves, in order to ensure the strength of the main shaft, the radial dimension of the shaft is relatively large; S...

Embodiment Construction

[0037] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] Such as Figure 7 As shown, when cutting the plate A, in order to improve the cutting accuracy, the gap between the upper scissors 1 and the lower scissors 3 depends on the thickness h of the plate to be sheared. Since the thickness h of the plate to be sheared is different, the relative positions of the upper scissors and the lower scissors 3 will also change accordingly. In order to ensure good cutting quality, the upper and lower scissors should be selected according to the thickness h of the plate to be sheared The overlapping amount S and the lateral gap δ of the upper and lower scissors. Figure 7 D is the diameter of the disc shear blade, h is the thickness of the plate to be sheared, α is the allowable bite angle, S is the overlapping amount of the upper and lower scissors, δ is the lateral clearance of the upper and ...

Abstract

The invention discloses a device for adjusting a gap of a shear of a disc shearing machine, which comprises an upper shear shank with an upper shear shaft and a lower shear shank with a lower shear shaft, wherein a transmission gear I is mounted on the upper shear shaft, a transmission gear II is mounted on the lower shear shaft, the transmission gear I is meshed with the transmission gear II, the upper shear shank and the lower shear shank are connected through a first positioning pull rod and a second positioning pull rod, two adjusting devices I are mounted on the two positioning pull rod, and the adjusting devices II are mounted on the upper shear shank. The invention further discloses a method for adjusting the gap of the shear of the disc shearing machine, which comprises the steps of moving the upper shear shank along the first positioning pull rod and the second positioning pull rod for adjusting the lateral gap between an upper shear and a lower shear and/or rotating the upper shear shank around the first positioning pull rod for adjusting the overlap of the upper shear and the lower shear. The structure of the adjusting device is simple, and the operation of the adjusting method is convenient and flexible, thereby being applicable to requirements of plates with different thicknesses, realizing high shearing precision and having no need of using special tools or detaching parts.

Description

technical field [0001] The invention relates to the field of disc shears, in particular to a device and method for adjusting the gap between scissors of a disc shear. Background technique [0002] When cutting the plate, in order to improve the cutting accuracy, it is necessary to reasonably set the gap between the upper and lower scissors according to the thickness of the plate to be cut. Due to the different thicknesses of the plates, the relative positions of the upper and lower scissors are also required to change accordingly, and the changes are mainly reflected in the side clearance and overlap of the upper and lower scissors. Therefore, in order to meet the needs of plates of various thicknesses, the existing disc shears all need to have the ability to adjust the side clearance and overlap. [0003] In order to meet the requirements of cutting products of different widths, the existing disc shears usually adjust the axial clearance of the blade (that is, the side cle...
