Abstract

The invention discloses a tappet centering device for a perforating machine, which solves the problems of inaccurate positioning and high possibility of bending of an ejector rod existing in the conventional perforating machine centering device. The device comprises a centering device base frame (7) fixedly arranged on a backstage second-segment base (16) and two lifting screw rod devices (10), wherein upwards output shafts of the two lifting screw rod devices (10) pass through the top surface of the centering device base frame (7) and then are fixedly connected with a supporting roller support (13); two supporting rollers (1) are parallelly arranged on the supporting roller support (13) along the direction of the ejector rod of the perforating machine; an oscillating rod support (3) and a hydraulic cylinder (5) are arranged on a mounting platform (6) respectively; the oscillating rod support (3) is hinged with the middle part of an oscillating rod (4) together through a hinge; the output shaft of the hydraulic cylinder (5) is connected with the tail part of the oscillating rod (4); and a compaction roller (2) is arranged on the head part of the oscillating rod (4). By the device, a tappet can be centered accurately, the requirement of supporting orientation of the ejector rod is met, and the ejector rod is prevented from bending.

Description

technical field [0001] The invention relates to a plug centering device of a piercing machine, in particular to a plug centering device for quick replacement of the piercing machine plug in the production of hot-rolled seamless steel pipes. Background technique [0002] The hot-rolled Wufeng steel pipe is rolled by a piercing machine. The basic process of piercing and rolling is: a closed pass is formed by a roll, a guide plate, and a plug, and the high-temperature metal is continuously deformed in the area formed by the pass. Finally, the hollow capillary is rolled out from the solid tube blank. Among them, the rolls and guide plates are relatively fixed and installed according to the process requirements, and the plug is installed on the ejector rod. According to the action requirements of the rolling cycle, the rolling position and the post-work position are periodically changed. Since the solid tube blank is perforated into a hollow capillary, the metal deformation is ...
