Example Embodiment

[0023] See Figure 4 , Figure 5 with Image 6 . The tube blank anti-throwing device of the present invention is installed on the entrance table of the piercing machine. The entrance table of the piercing machine includes a base 1, a tube base 2 mounted on the base 1. A tube base lifting hydraulic cylinder 3 is provided between the tube base 2 and the base 1, and the tube base 2 is provided with Place the V-groove of the tube blank. The tube billet anti-spin device includes: a pair of stop bar lifting devices 6, a stop bar 7, a push-pull device 8 and a connecting block 9 installed on both sides of the base 1 opposite to each other.

[0024] The push-pull device 8 includes two push-pull seats 81 fixedly installed on the ground and a push-pull hydraulic cylinder 82 horizontally installed on the two push-pull seats 81. If the push-pull seat is relatively large, only one can be used, but two are preferably used, which not only enables the push-pull hydraulic cylinder 82 to be insta...

Abstract

The invention discloses a pipe billet whip preventing device and a punching machine. The pipe billet whip preventing device comprises a push-and-pull unit, a connection block, a stop bar and a pair of stop bar lifting units. The push-and-pull unit comprises a push-and-pull hydraulic cylinder; the left end of the connection block is adjustably connected with an ejecting end of a push-and-pull piston rod of the push-and-pull hydraulic cylinder in a vertical direction; the stop bar lifting units in pair are mounted on two sides of an inlet table base of the punching machine oppositely, each stopbar lifting unit comprises a support, a guide frame, a slider and a slider lifting hydraulic cylinder, wherein the slider is mounted in the guide frame and capable of sliding vertically relative to the guide frame, the left end of the stop bar is fixedly connected to the connection block and the right end of the stop bar penetrates through a through hole, and a lifting piston rod of the slider lifting hydraulic cylinder is hinged to the bottom end of the slider. The punching machine comprises the pipe billet whip preventing device. The pipe billet whip preventing device and the punching machine can be adaptable to pipe billets of different diameters, guarantee stability in punching process, protect outer surfaces of the pipe billets from being scratched and guarantee fine quality of the pipe billets.

Description

technical field [0001] The invention relates to a seamless steel pipe piercing equipment, in particular to a pipe blank anti-swing device and a piercer for preventing the pipe blank from swinging when the piercing machine inlet platform prevents the steel from being bitten. Background technique [0002] Tube blank piercing is one of the important processes in the production of hot-rolled seamless steel pipes. This process is to wear and roll solid tube blanks into hollow capillary tubes. It is the first process of metal deformation. The main equipment used in this process is a piercer. [0003] The process of piercing the tube blank is as follows: the roll of the piercing machine rotates, the ejector trolley drives the plug and the ejector pin to the working position, the heated tube blank is placed into the V-shaped groove of the inlet table, and the tile buckle device (tube blank anti-swing device) is closed. A pusher pushes the tube billet into the main frame of the pierc...
