Novel longitudinal-cutting disc plate shearing machine

Abstract

A novel longitudinal-cutting disc plate shearing machine comprises a rack and a spindle portion. The spindle portion comprises two spindles with parallel axes, a plurality of pairs of knife holders inup-down arrangement are mounted on the spindles, disc knives are mounted in the knife holders, and the spindles are spline spindles; each knife holder comprises a spline sleeve matched with the corresponding spline spindle, and each disc knife is fixed on the corresponding spline sleeve; each knife holder further comprises at least one bearing seat having at least one fixed end which is locked ona rack by a locking cylinder. The knife holders are used to replace space sleeves and rubber sleeves in the prior art, so that when knife rearranging is needed, position of each knife holder where the corresponding disc knife is positioned can be adjusted by only loosening the locking oil cylinder, adjusting is simple and convenient, time needed for adjusting is saved greatly, and using cost is lowered.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a slitting disc shearing machine used in an uncoiling slitting and slitting production line. Background technique [0002] The slitting disc shearing machine used in the traditional steel coil uncoiling and leveling production line is driven by the main shaft to complete the slitting and slitting of the corresponding disc knives sleeved on the upper and lower main shafts. The defective of this disc shearing machine is embodied in: [0003] 1) Due to the need to meet the shearing of plates with different widths and thicknesses, a large number of spacers and rubber sleeves of different specifications are required, which increases the production and use costs, and the re-arrangement of tools caused by changing the steel coil specification greatly affects production efficiency; [0004] 2) Due to the need to re-arrange the knives, the slitting disc shearing machine sho...

AI Technical Summary

Problems solved by technology

[0003] 1) Due to the need to meet the shearing of plates of different widths and thicknesses, a large number of spacers and rubber sleeves of different specifications are required, which increases the production and use costs, and the re-arrangement of knives caused by changing the steel coil specification greatly affects production efficiency;

[0004] 2) Due to the need to re-arrange the knives, the slitting disc shears should be moved out of the production line as a whole, and one side of the pillar also needs to be moved sideways to facilitate the replacement of blades, spacers and rubber sleeves. The overall rigidity and accuracy are very low due to too many moving parts. Difficult to guarantee;

[0005] 3) In order to ensure a small deflection, the main shaft should have a sufficiently large diameter, and the material requirements of the main shaft are high. Generally, alloy structural steel is used, so the cost of the upper and lower main shafts is high
