Detailed Description

Referring to fig. 1-6, the present invention provides a technical solution:

a knife-edge clearance adjusting device of a numerical control plate shearing machine comprises a plate shearing machine body 1, wherein a lower pressing shearing knife part 101 is arranged in the middle of the plate shearing machine body 1, a limiting groove 102 is formed in the right wall of the plate shearing machine body 1, a scale gauge is arranged on the top surface of the limiting groove 102 to facilitate knife-edge spacing adjustment and selection, a knife plate fixing block 103 is arranged in the limiting groove 102, a lower knife 104 is screwed on the right wall of the knife plate fixing block 103, an adjusting screw 105 is screwed on the left wall of the knife plate fixing block 103, a shearing frame 2 is screwed on the right wall of the plate shearing machine body 1, a scale is arranged on the top surface of the shearing frame 2 to facilitate plate shearing length adjustment, a bearing plate 3 is arranged in the middle of the shearing frame 2, a supporting plate 301 is hinged on the lower portion of the bearing plate 3, a torsion arm spring 302 is arranged in the middle of the supporting plate 301 to facilitate the sheared plate to fall into a plate material box 4, a plate material box 4 is arranged on the bottom surface of the shearing frame 2, a feeding frame 5 is screwed on the left wall of the plate shearing frame 1, the feeding frame 5 is rotatably connected with a plurality of rollers 501 in a linear equidistant structure, the top surface of the feeding frame 5 is in a front-back symmetrical structure and is in a threaded connection with two material baffle plates 502, and the inner sides of the material baffle plates 502 are in a linear equidistant structure and are rotatably connected with a plurality of rotating columns 503, so that the plate feeding is more labor-saving.
