Detailed Description

The following are specific embodiments of the present application and are further described with reference to the drawings, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help the embodiments of the present application be fully understood. Accordingly, it will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

In addition, the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

In the embodiment of the application, the shearing machine comprises a fixed cutter fixedly arranged and a movable cutter holder 100 provided with a movable cutter; the movable blade holder 100 is capable of linearly reciprocating to combine or separate the movable blade with the stationary blade. In the gantry shearing machine, when the movable tool rest 100 moves downwards, the movable tool and the fixed tool are combined to shear materials. After one cutting is completed, the movable blade holder 100 is separated from the stationary blade by moving up to a predetermined position for the next cutting.

Referring to fig. 3 and 4, the movable blade holder includes: moving blade mount 10, moving blade 20. The movable knife 20 is arranged on the movable knife mounting seat 10, and the movable knife 20 is provided with a shearing cutting edge 20p consisting of a transverse cutting edge 21 and a longitudinal cutting edge 22 which are alternately formed; the orthographic projection of the shearing cutting edge 20p along the moving direction of the movable tool rest is step-shaped; a concave inner corner 23 or a convex outer corner 24 is formed between the adjacent transverse cutting edge 21 and the longitudinal cutting edge 22; the cutting edges 21 and the longitudinal edges 22 used to form the outer corner 24 are of uniform height at the corner transition locations to continue together to form a continuous edge or are staggered in height by less than 30 mm.

In the present embodiment, the cutting edges 20p are bent. Referring to fig. 3, the shearing edge 20p is stepped in an orthographic projection along the moving direction of the movable blade holder.

In the embodiment of the present application, referring to fig. 3, a concave inner corner 23 or a convex outer corner 24 is formed between the adjacent cutting edges 21 and 22; the cutting edges 21 and the longitudinal edges 22 used to form the outer corner 24 are highly uniform at the corner transition position to be continuous to form continuous edges. The transverse cutting edges 21 and the longitudinal cutting edges 22 at the outer corners 24 are consistent in height to form continuous cutting edges, so that the movable knife installation base 10 can be prevented from protruding downwards from the shearing cutting edges 20p too much at the corner transition position, the extrusion of materials on the movable knife installation base during shearing is reduced, the movable knife installation base 10 is not easy to damage, and the service life is longer.

In addition, the transverse cutting edges 21 and the longitudinal cutting edges 22 for forming the outer corners 24 are staggered within 30mm in the height of the corner transition positions, so that the movable knife installation base 10 is prevented from protruding downwards from the shearing cutting edges 20p too much in the corner transition positions, the extrusion of materials on the movable knife installation base 10 during shearing is reduced, the movable knife installation base 10 is not easy to damage, and the service life is longer.

Referring to fig. 3, each of the shearing edges 20p corresponds to one of the blade divisions 20a for each of the lateral cutting edges 21 and the longitudinal cutting edges 22. The inner corner 23 and the outer corner 24 of the cutting edge 20p are present at the position where the two blade split bodies 20a are engaged. Since the thickness of the blade body 20a is much smaller than the length of the cutting edges on the blade body 20a, where the cutting edges formed in the thickness direction of the blade body 20a are neglected at the inner corner 23 and the outer corner 24, a section of the lateral cutting edge 21 or a section of the longitudinal cutting edge 22 is formed by a single blade body 20a, and the position where the adjacent blade bodies 20a are joined is regarded as the bending transition position of the inner corner 23 and the outer corner 24.

In some embodiments, the cutting edges 21 and 22 used to form the inner corner 23 are highly uniform at the corner transition location to form continuous edges together. So set up, whole shearing blade 20p is continuous blade.

In some embodiments, referring to fig. 4, all of the lateral edges 21 and all of the longitudinal edges 22 are deflected either entirely upward or entirely downward along the extension direction S of the cutting edges 20 p. With the arrangement, when the movable knife rest 100 moves downwards, the cutting edge 20p of the movable knife and the fixed knife can be gradually combined to cut materials, and the required driving power is small.

In addition, the movable blade 20 may be divided into a plurality of blade divisions 20a in other possible division manners.

In the present embodiment, the cutting edges 20p of the movable blade 20 are bent, and the horizontal cutting edges 21 and the longitudinal cutting edges 22 for forming the outer corner 24 are consistent in height at the corner transition position to be connected together to form a continuous cutting edge. So set up, can avoid moving the sword mount pad in the downward too much protrusion in shearing blade of corner transition position to the extrusion of material to moving the sword mount pad when having reduced the shearing, make to move sword mount pad 10 not fragile, life is longer.
