Novel special-shaped billet head turning device and operation and control process thereof

The invention belongs to the technical field of rolling production of special steel bars, particularly relates to a novel special-shaped billet head turning device and an operation and control process thereof, and solves the problem that existing head turning equipment used on production site of special-shaped steel bars is heavy, complex in operation and time-wasting. The novel special-shaped billet head turning device comprises a support, a worm gear case, a sensing frame, an approach switch, a coupler, a brake, a motor, an air cylinder, a feather key, a tensile shaft and a feed frame, wherein the approach switch is arranged on the upper portion of the outer side of the sensing frame, the sensing frame is connected with the feed frame through the feather key and the tensile shaft, and the worm gear case is connected with the motor through the coupler and the brake. The novel special-shaped billet head turning device realizes online quick head turning, rolling time is shortened, temperature reduction of billets is reduced to the greatest extent, and original characteristics of rolled steel are guaranteed. By the aid of automation control, the novel special-shaped billet head turning device is simple to operate and durable, and technical design is optimized, so that the billets can be rolled by better rolling routes, factory arrangement is saved, and investment is reduced by about 1 million.
