Problems solved by technology

The lifting structure of the existing plug circulation replacement device directly acts on the plug, and the plug is conical. Affected by the position of the plug, it is difficult to precisely control the height of the straightening, which often causes the plug to penetrate unsuccessfully, not in place, and the locking fails. head drop accident

Abstract

The invention relates to a circular-replacing device for a perforator top head, and belongs to the field of hot-rolling seamless steel pipe production equipment. The circular-replacing device comprises a replacing device and a lifting-centering device, wherein a plurality of saddles are arranged in the replacing device; a containing groove used for containing the top head is arranged above the saddles; on end of each saddle is rotatably arranged on the replacing device; the lifting-centering device acts on the other end of each saddle; and the top head rotates along with the saddles under thedriving of the lifting-centering device. In the circular-replacing device, one end of each saddle is rotatably arranged, the lifting-centering device acts on the other end of each saddle, the lifting-centering device directly acts on the lower saddle to eliminate an influence of the shape of the top head on lifting-centering height, and top head lifting-centering accuracy is improved so as to be favorable for a supporting rod to successfully and correctly penetrate into the top head, a top head replacement success rate is improved, and a top head falling accident is reduced.

Description

technical field [0001] The invention belongs to the field of hot-rolled seamless steel pipe production equipment, and relates to a piercing machine plug circulation replacement device. Background technique [0002] In various hot-rolled seamless steel pipe production processes, the piercing machine is used to perforate the solid tube billet. The piercing machine is mainly composed of the front billet pusher, the main body, the first stage of the background, and the second stage of the background. [0003] The main body of the piercing machine is arranged with two tapered rolls up and down. The axes of the rolls form a certain angle. The rolls are driven by a motor and a reducer. [0004] The exit of the piercing machine is arranged in turn with the first section of the backstage and the second section of the backstage. The first section of the backstage is mainly composed of 5-6 centering rollers and a set of transport rollers. The head cycle replacement device, the second ...
