Embodiment

[0034] The specific embodiment of the present invention is as Figure 1-3 As shown, a progressive rotary shearing machine capable of maintaining the distance between the cutters includes a fixed knife plate 1 and a moving knife plate 2 arranged parallel to the plate surface, and the fixed knife plate 1 and the moving knife plate 2 are provided with workpiece sockets, and The workpiece sockets on the two boards are arranged coaxially. The workpiece socket on the fixed knife plate 1 is provided with a fixed knife 11, and the workpiece socket on the movable knife plate 2 is provided with a moving knife 21. The shearing machine also includes a driving mechanism and a knife distance maintaining mechanism. The driving mechanism includes a rotating shaft 4 that passes through the fixed knife plate 1 and the moving knife plate 2 vertically.

[0035] The knife distance maintaining mechanism includes two thrust bearings 6 oppositely arranged on the facing away surfaces of the fixed kn...

Abstract

The invention discloses a progressive rotary shearing machine capable of keeping the distance between cutters, relates to the field of progressive rotary shearing machines, and is mainly used for solving the problems that a gap between a movable cutter and a fixed cutter is increased and shearing cannot be carried out due to the fact that the movable cutter and the fixed cutter of the progressive rotary shearing machine can generate component force during shearing. According to the main structure, the cutter distance maintaining device comprises a driving mechanism and a cutter distance maintaining mechanism, the cutter distance maintaining mechanism comprises two thrust bearings which are oppositely arranged, a mounting channel coaxial with the two thrust bearings is arranged between the two thrust bearings, and a pull rod which is eccentrically arranged in the same direction as a shaft sleeve is arranged in the mounting channel; and one end of the pull rod is rotationally clamped and matched with the thrust bearing on the fixed cutter plate, and the other end of the pull rod is provided with a locking nut. According to the progressive rotary shearing machine capable of keeping the distance between the cutters, by arranging the cutter distance keeping mechanism, component force generated by the movable cutter and the fixed cutter in the shearing process can be overcome, the distance between the movable cutter and the fixed cutter is kept unchanged, and then shearing is conducted normally.

Description

technical field [0001] The invention relates to the field of progressive rotary shears, in particular to a progressive rotary shear capable of maintaining the distance between cutters. Background technique [0002] The existing progressive rotary shearing machine generally drives the moving knife plate through the rotation of an eccentric shaft that vertically passes through the fixed knife plate and the moving knife plate, so that the moving knife can perform constant-speed spiral involute motion relative to the fixed knife , thus completing the cut. [0003] During the shearing process, a reasonable gap should be maintained between the moving knife and the fixed knife according to the specifications of the shearing material, so as to ensure the quality of the shearing section and the smooth progress of shearing. However, since a huge component force will be generated between the moving knife and the fixed knife during shearing - the force that separates the cutting edges ...
