Description

Seamless steel tube perforating machine and rotary drum locking device thereof Technical Field The invention belongs to the technical field of seamless steel tube piercing machines, and particularly relates to a seamless steel tube piercing machine and a rotary drum locking device thereof. Background In the field of industrial manufacturing, steel rolling machinery is core equipment for realizing plastic working of steel, wherein a seamless steel pipe is used as a key steel product with wide application, and the advancement of the production process directly determines the quality and the production efficiency of the product. The perforating machine is used as core equipment in seamless steel pipe production and is mainly responsible for processing a solid pipe blank into a hollow pipe, the rotary drum is used as a key moving part of the perforating machine, the stability of the perforating machine during working directly influences the perforation precision, the product qualification rate and the equipment operation safety, and the rotary drum locking device of the perforating machine is a core matching device for guaranteeing the stable operation of the rotary drum, so that the rotary drum locking device has an irreplaceable effect on the smooth development of the whole perforation process. However, the existing drum locking device of the puncher still has obvious technical defects, and the high-efficiency and stable production requirements are difficult to meet. On the one hand, the movable end of the existing locking device is arranged on the side face of the perforating machine, the arrangement mode enables the locking acting force direction to be perpendicular to the axial force direction born by the rotary drum during working, the locking force of the locking cylinder cannot effectively offset the axial force, and the overall locking effect is greatly weakened. On the other hand, the existing device adopts the structural design that the locking cylinder directly acts thrust on the rotary drum, so that the force applied to the rotary drum is concentrated in a local area, the force applied area is small, the local abrasion of the rotary drum is easy to cause, the stability of the rotary drum in high-speed operation is poor, the problems of vibration, deviation and the like are easy to occur, the perforation quality and the service life of equipment are influenced, and in sum, a seamless steel tube perforating machine and a rotary drum locking device thereof are needed. Disclosure of Invention In order to solve part or all of the technical problems in the prior art, the invention provides a seamless steel tube puncher and a rotary drum locking device thereof. In one aspect of the invention, a drum locking device of a seamless steel tube perforating machine is provided, the drum locking device is arranged on a frame of the seamless steel tube perforating machine, the drum locking device comprises two fixing components symmetrically arranged on the inner side of the frame and two locking components symmetrically arranged on the inner side of the frame, wherein: The fixing assembly comprises a first base fixed on the frame and a fixing sliding plate arranged on the first base through a first fastener, and the central axis of the first base is inclined to the central axis of the frame; The locking assembly comprises a second base fixed on the frame and a movable sliding plate arranged at the end part of the second base, wherein the central axis of the second base is inclined to the central axis of the frame, a plurality of first accommodating grooves are uniformly distributed on the second base, a second accommodating groove is formed between two adjacent first accommodating grooves, a hydraulic cylinder is arranged in the first accommodating groove, a push rod of the hydraulic cylinder is connected with a T-shaped push head, and a guide column is fixed in the second accommodating groove through a second fastener; The movable slide inboard set up match in the third holding tank of pneumatic cylinder, the third holding tank lateral wall set up match in the T type push away the spacing groove of head, the T type push away the head card and locate in the spacing groove, set up the fourth holding tank between two adjacent third holding tanks, the fourth holding tank embedded be equipped with match in the uide bushing of guide post, the uide bushing is for running through the setting, guide post sliding connection in uide bushing inner wall. Further, in the drum locking device of the seamless steel tube perforating machine, an end plate is arranged at one end, close to the second base, of the guide sleeve, a fixing hole is formed in the end plate, and the end plate is fixedly connected with the inner side of the movable sliding plate through a third fastener matched with the fixing hole. Further, in the drum locking device of the seamless steel tube puncher, the number of the first accommodating grooves is 3-5.
