Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings, but the scope of protection of the present invention is not limited to the accompanying drawings.

[0029] The reciprocating hydraulic oil cylinder used in the present invention is Qiangfeng hydraulic YG003 type reciprocating hydraulic oil cylinder, and the motor is the LSD / Leisun 5IK90RGU-CF forward and reverse motor produced by Dongguan Laishidun Electromechanical Technology Co., Ltd.

[0030] figure 1 It is a schematic diagram of the position of the burr after the round billet is cut by fire. As shown in the figure, the round billet continuous casting machine uses flame cutting to cut the round billet 3 into a fixed length. Flame cutting will inevitably form a slag burr 11 at the lower part of the cut.

Abstract

The invention relates to the technical field of continuous casting production, in particular to a deburring machine for a round billet and a working method of the deburring machine. The deburring machine comprises a left arc-shaped serrated knife and a right arc-shaped serrated knife which are mounted in the advancing direction of a casting billet in a front-back manner, are integrally located inthe middle of a roller bed and are fixedly connected to the free end of a piston rod of a reciprocating hydraulic oil cylinder; the reciprocating hydraulic oil cylinder is fixed to a knife holder; when the piston rod of the reciprocating hydraulic oil cylinder completely stretches out, a center perfect circle machining hole is formed in the front portion and the rear portion of the left arc-shapedserrated knife and the right arc-shaped serrated knife; and scraping is generated in the casting billet retreating process, and the effect of deburring is achieved. According to the deburring machine, the roundness of the round casting billet can be guaranteed while deburring is carried out, the shape of the casting billet cannot be damaged, and the quality of the casting billet is guaranteed. Compared with high-speed rotating striking of a hammer knife, reciprocating motion scraping has the beneficial effects that safety is achieved, filings cannot be splashed, noise is low, and 360-degree complete deburring is achieved.

Description

technical field [0001] The invention relates to the technical field of continuous casting production, in particular to a deburring machine for round blanks and a working method thereof. Background technique [0002] The existing round billet continuous casting machine uses flame cutting to cut the continuous casting billet into a fixed length. Flame cutting will inevitably form slag burrs at the lower part of the incision. If the quality problem is serious, the roll will be damaged. In order to improve the product quality and reduce the impact of the billet cutting burr on the hot rolling process. At present, the round billet deburring machine is a hammer-knife type, and the purpose of deburring is achieved by hammer-knife rotating and striking at high speed. However, in actual use, the round billet rotates on the roller table after flame cutting, and the deburring rate cannot reach 100%, and the unremoved burrs still need to be manually cleaned and removed.
