Description

Technical Field

[0001] The utility model relates to the field of shearing equipment, in particular to a shearing mechanism and a shearing machine provided with the shearing mechanism. Background Art

[0002] The swing-head shearing machine can adjust the angle between the cutting edge of the plate to be cut and the feeding direction of the plate to be cut. The adjustment of the above angle relies on the horizontal deflection of the shearing mechanism in the swing-head shearing machine. The drive motor used to realize the up and down movement of the upper shearing blade in the existing shearing mechanism rotates together with the upper and lower shearing blades. The drive motor and its auxiliary mechanisms rotate synchronously with the upper and lower shearing blades, and the overall rotation mass is large. Therefore, the upper and lower shearing blades rotate slowly, affecting the shearing speed of the plate. At the same time, the power consumption of the drive motor used to realize the rotation of the upper and lower shearing blades is also relatively large. At the same time, the shearing mechanism in the existing swing-head shearing machine has no peripheral protection, and there is a certain safety risk for the user when the upper and lower shearing blades are horizontally deflected.

[0003] Therefore, how to provide a shearing mechanism that can overcome the above problems is an issue that those skilled in the art need to solve urgently. Utility Model Content

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The utility model discloses a shearing mechanism. The utility model designs a mounting frame 2, the reciprocating telescopic member and the driving machine 9 are both mounted on the mounting frame 2, and the movable knife table 10 and the fixed knife table 11 are both limited inside the mounting frame 2. On the one hand, the reciprocating telescopic member, the driving machine 9, the movable knife table 10 and the fixed knife table 11 can be reliably arranged, and on the other hand, when the movable knife table 10 and the fixed knife table 11 are horizontally deflected, the mounting frame 2 can play a certain safety protection role;

[0030] The reciprocating telescopic end of the reciprocating telescopic member in the present application is rotatably connected to the movable tool table 10, and the rotation axis coincides with the axis of the output shaft of the driving machine 9. When the driving machine 9 drives the movable tool table 10 and the fixed tool table 11 to deflect horizontally, the reduction motor 3, the connecting shaft 4, the eccentric bearing 5, the connecting block 6 and the connecting rod 7 in the reciprocating telescopic member will not deflect horizontally with the movable tool table 10. This design can greatly reduce the rotation load of the driving machine 9. On the one hand, it can increase the horizontal deflection speed of the movable tool table 10 and the fixed tool table 11, thereby improving production efficiency. On the other hand, it can reduce the power consumption of the driving machine 9.

[0031] By designing the limiting tube 14 and the limiting column 15, the design ensures that the movable knife stage 10 and the fixed knife stage 11 can be synchronously deflected horizontally. At the same time, when the movable knife stage 10 moves down, the movable knife stage 10 and the fixed knife stage 11 can be accurately aligned to ensure that the two can effectively cut the plate to be cut;

[0032] The reciprocating telescopic member uses an eccentric bearing 5, a connecting block 6, a connecting rod 7 and a ball hinge 8 to realize the reliable up and down movement of the movable tool table 10. At the same time, due to the design of the ball hinge 8, when the movable tool table 10 moves up and down, the driving machine 9 can also drive the movable tool table 10 to deflect horizontally reliably;

[0033] The shearing machine provided with the shearing mechanism has high shearing efficiency and relatively low failure rate and energy consumption.
