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.

The invention discloses a circular disc edge cutting device. The circular disc edge cutting device comprises an upper tool rest, a lower tool rest, an upper tool shaft, a lower tool shaft, an upper tool pan, a lower tool pan and an adjusting mechanism, wherein the adjusting mechanism is a multi-link adjusting mechanism formed by adopting an eccentric shaft and link rods; and the adjustment of theside clearance and the overlap quantity of the tool pans can be realized by rotating the eccentric shaft. In the circular disc edge cutting device, the eccentric shaft replaces a turbine, a worm and an eccentric wheel adjusting mechanism in the prior art, the complexity of equipment and the requirement on installation and maintenance are reduced, and simultaneously the manufacturing cost of the equipment is cost; the side clearance and the overlap quantity of the tool pans are adjusted by adopting a full-eccentric shaft, the influence on the occlusion clearance between the turbine and the worm in an original technology is eliminated, the adjustment precision is improved, and simultaneously the machining requirement is reduced so that the machining cost is reduced; in addition, a motor is arranged at one end of the eccentric shaft, and a hand wheel is arranged at the other end of the eccentric shaft, so that full-automatic and manual adjustment of the side clearance and the overlap quantity can be realized very conveniently; therefore, the circular disc edge cutting device has extremely high popularization and application values.
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 has a very close relationship with the side clearance and overlap of each side of the cutter head. It can be known from production practice that when cutting metal strips or plates with different thicknesses, the size of the side clearance and overlap of the cutter head is also different. Make adjustments. [0003] In the existing technology, the adjustment of the side clearance and overlap of the cutter head is realized by the form of a worm gear and an eccentric wheel, such as patents 200720083199.4, 2007...
