Abstract

The invention discloses a cooling tank device of a hot-rolling perforation machine set, relating to hot-rolling perforation machine set equipment. The invention solves the problems that the existing cooling tank device has large occupied area, large cooling water requirement amount, poor cooling effect and inaccurate mandril control so as to affect normal production operation. The invention is characterized in that in-bound equipment is an in-bound device (10) which is composed of a hydraulic cylinder (10-1), five material toggling grooves (10-2), a rotary shaft (10-3) and five bearing pedestals (10-4); the bottom of a cooling trough (4) is welded with five semicircular mandril slideways (4-2); a rotary device utilizes a support frame arranged outside the cooling trough and a rotary drum device (9) arranged right above the cooling trough (4); and a control mechanism is a controller 11 consisting of a profile modelling disk (11-1) and an approach switch (11-2).

Description

technical field

[0001] The invention belongs to steel rolling machinery equipment, in particular to a cooling tank device used by a hot rolling piercing unit in the production of seamless steel pipes. Background technique

[0002] In the current production of seamless steel pipes, the hot-rolled piercing unit with circulating ejector pins is used. During the piercing process, multiple ejector pins need to be cooled in turn to ensure the allowable use temperature of the ejector pins; after working in red steel at 1000 ℃ The ejector rod or mandrel enters a cooling tank filled with water in sequence, and then a special mechanical device that is taken out and reused is called a cooling tank device.

[0003] Taking the circulation ejector as an example, the current cooling tank device, such as figure 1 , 2 As shown: It is composed of feeding roller table 1, dial-in mechanism 2, putting device 3, cooling tank 4, adjusting device 5, wheel device 6, and discharging platform 7. Th...
