Problems solved by technology
This adjustment mechanism includes components such as turbine, worm, eccentric wheel, etc. The system is very complicated, and installation and maintenance are very inconvenient
At the same time, this adjustment mechanism has higher requirements on machining accuracy and assembly accuracy, so the manufacturing cost is higher
At the same time, due to the occlusal clearance of the worm gear, the adjustment accuracy of this adjustment mechanism is not high.

Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with the accompanying drawings: the disc trimmer of the present embodiment includes a knife rest 1, an upper knife shaft 2 and a lower knife shaft 3 that are rotatably matched with the knife rest 1, and are fixedly arranged on the upper knife shaft respectively. 2 and one end of the lower cutter shaft 3 form the upper cutter head 4 of the shear structure, the lower cutter head 5 and the adjustment mechanism for adjusting the backlash d of the upper and lower cutter heads. The adjustment mechanism includes an eccentric shaft 6 and a connecting rod 7. The eccentric shaft 6 is rotatably arranged relative to the tool holder 1 in a manner that can rotate around its fixed center 6a. The rotational center 6b of the eccentric shaft 6 is rotatably matched with one end of the connecting rod 7. The rotational axis of the eccentric shaft is the eccentric shaft The axis center of the upper eccentric section, the f...

The invention discloses rotary trimming shears. The rotary trimming shears comprise a tool rest, an upper cutter shaft, a lower cutter shaft, an upper cutterhead, a lower cutterhead, and an adjusting mechanism for adjusting the lateral clearance quantities of the upper cutterhead and the lower cutterhead, wherein the adjusting mechanism adjusts lateral clearances of the cutterheads by rotating an eccentric shaft and a connecting rod. According to the invention, eccentric shaft and connecting rod structures are used for substituting a turbine, a worm and an eccentric bushing regulating mechanism in the prior art, so that the complexity of equipment and the requirements on the installation and maintenance are reduced, and the manufacturing cost of the equipment is also reduced; the full eccentric shaft is used for adjusting the lateral clearances of the cutterheads, so that the influence of an occlusal clearance between the turbine and the worm in the prior art is eliminated, the adjusting accuracy is improved, the processing requirements are also reduced, and the processing cost is reduced; in addition, a motor is arranged at one end of the eccentric shaft, and a handwheel is arranged at the other end of the eccentric shaft, so that the full automatic and manual adjustment of the lateral clearances of the cutterheads can be conveniently realized, and the rotary trimming shears have high popularization and application value.
Description
technical field [0001] The invention relates to strip and plate processing equipment in steel rolling production, in particular to a strip trimming equipment. Background technique [0002] In the production process of metal strips and plates, trimming is a very common production step. At present, all production lines use disc-type trimming devices to trim metal strips and plates. For disc-type trimming As far as the edge device is concerned, the quality of edge trimming is closely related to the side clearance of each cutter head. It can be known from production practice that when cutting metal strips or plates of the same thickness, the size of the side clearance of the cutter head is also different. Therefore, it is necessary to adjust the side clearance of the cutter head when producing metal strips or plates of different thicknesses. [0003] In the existing technology, the adjustment of the side clearance of the cutter head is realized in the form of a worm gear and an...
