Embodiment Construction

[0016] see figure 1 , figure 2 , image 3 , four pairs of cutterheads (upper cutterhead device 11 and lower cutterhead device 12) are installed in the disc shear frame 14 to cut the two sides of the steel plate together. Tangentially cut steel plate. Because the thickness of the sheared steel plate is relatively large, there are powerful pinch rollers 9 installed before and after the disc shears, which are hydraulically balanced and hydraulically depressed powerful pinch roller devices, and its function is to make the steel plate easily enter between the upper and lower cutter heads, It can also increase the rigidity during the movement of the steel plate so that the shearing process can be carried out stably. Each pair of cutterheads is provided with a pressure roller mechanism 6 at the upper cutterhead 11. The moving mechanism 7 of the left and right frames of the disc shears is equipped with an electric screw device, which is composed of a motor, a reducer, a screw nut...

Abstract

The invention provides a multi-cutter type combined disc shear used in a medium-thick plate rolling line and a strip finishing line. It is installed in the frame of the disc shears with four pairs of cutter heads that can jointly cut the two sides of the steel plate. The upper and lower cutter heads are equipped with a gap adjustment mechanism and an overlap adjustment mechanism. There are powerful pinch rollers, each pair of cutterheads is equipped with pressure rollers on the upper cutterhead, and the left and right frames of the disc shears are equipped with electric screw devices. This kind of disc shear can not only maintain the advantages of continuous shearing of steel plates by disc shears, but also make the thickness of the sheared steel plates reach 40-50mm. It is a new type of structure that can continuously shear medium-thick steel plates on both sides.

Description

technical field [0001] The invention relates to a multi-cutter type combined disc shear, which is a high-efficiency shearer used in a medium-thick steel plate rolling line and a strip finishing line of metallurgical machinery. Background technique [0002] As far as the applicant's professional production research is known: So far, the domestic disc shears used in the plate rolling line and strip steel finishing line are all equipped with two pairs of cutter heads in one shearing machine, called It is two pairs of disc cutters. Disc shears have high shearing speed and continuous shearing, which is the biggest advantage of disc shears. When this disc shear works, each pair of cutter heads cuts one side of the steel plate, and when cutting a 10mm thick steel plate, the shearing speed can reach 100m / min. When cutting a 30mm thick steel plate, the shearing speed can reach 80m / min. However, the shearing capacity of the two pairs of disc shears is limited, and the thickness of ...
