Description

Hot roll table pinch device that send of continuous casting square billet

Technical Field

The utility model belongs to the mechanical equipment field relates to a roll table clamp send device is sent to continuous casting square billet heat.

Background

The continuous casting billet hot charging and hot conveying is a production process that after a continuous casting billet produced in steel making is subjected to flame cutting, the continuous casting billet is directly conveyed to a steel rolling heating furnace through a hot conveying roller way without being placed and cooled, and is directly rolled after being heated in the furnace. The temperature of the steel billet entering the heating furnace can reach 600 ℃ at most, so that the energy consumption of the heating furnace is effectively reduced, the burning loss of the steel billet is reduced, and the yield is greatly improved. The hot steel billet adopts the roll table to transport to steel rolling workshop heating furnace from the continuous casting area in steelmaking workshop, because of the technology needs, square billet is "state" during the transport, so the cell type of conveying roller is 90 degrees V-arrangement of assorted with it, in actual production, because the unevenness and the deformation on steel billet surface cause its and rollgang within a definite time area of contact diminish, make frictional force reduce in the transportation cause the steel billet phenomenon of skidding, cause to carry unsmoothly, influence production.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved is as follows: to the technical problem, the utility model provides a hot roll table of sending of continuous casting square billet presss from both sides and send device.

The technical scheme is as follows: a continuous casting billet hot-delivery roller way clamping and conveying device comprises: the device comprises a first base, a second base, a cylinder, a rotating arm, a rotating shaft, a bearing seat, an upper roll frame, an upper roll and a fixed arm; the cylinder is fixed on the first base through a cylinder frame, a shaft sleeve is sleeved on the rotating shaft and fixed in a bearing seat, the bearing seat is arranged on the second base, and the second base is higher than the first base; one end of the rotating arm is connected with a piston of the air cylinder, the other end of the rotating arm is connected with one end of the rotating shaft, one end of the fixed arm is fixedly connected with the upper roll frame, and the other end of the fixed arm is connected with the other end of the rotating shaft; the upper roller is fixed on the lower surface of the upper roller frame through a bearing seat.

Detailed Description

Example 1

The present invention will be further explained with reference to the accompanying drawings.

As shown in figures 1-5, the utility model provides a continuous casting billet hot-feeding roller way clamping and conveying device,

the air cylinder 3 is fixed on the first base 1 through an air cylinder frame, a shaft sleeve is sleeved on the rotating shaft 6 and is fixed in a bearing seat 7, the bearing seat 7 is arranged on the second base 2, and the second base 2 is higher than the first base 1; one end of the rotating arm 4 is connected with a piston of the cylinder 3, the other end of the rotating arm is connected with one end of the rotating shaft 6, one end of the fixed arm 10 is fixedly connected with the upper roller frame 8, and the other end of the fixed arm is connected with the other end of the rotating shaft 6; the upper roller 9 is fixed on the lower surface of the upper roller frame 8 through a bearing seat.

The first base 1 is connected with the second base 2 through welding, and stability is improved. A key and a corresponding key groove are arranged between the connecting parts of the rotating shaft 6 and the fixed arm 10 and are used for axially fixing the rotating shaft and the fixed arm; and a key and a corresponding key groove are also arranged between the connecting parts of the rotating shaft 6 and the rotating arm 4 and are used for axially fixing the rotating shaft and the rotating arm.

The device is arranged beside a continuous casting square billet hot conveying roller way, a continuous casting square billet hot conveying roller is a lower roller (conveying roller) with a drive to provide billet conveying power, an upper roller in the device is a free roller, and the upper roller is aligned with a lower roller. The cylinder is connected with the upper roller through the rotating shaft, and the structure enables the cylinder element to be far away from the high-temperature billet and increases the moment. The square billet 12 on the lower roller is clamped by the upper roller through controlling the action of the air cylinder, so that the billet in transportation is clamped forwards. Simultaneously, optimize the roll shape of upper and lower roll, the bottom design of roller V-arrangement face is 75 degrees contained angles for the steel billet contacts roller V-arrangement face both sides, has increased the friction surface, has further promoted the pinch effect. In addition, because of upper and lower roller direct contact steel billet, in order to avoid the influence of high temperature to the bearing, water-cooled bearing frame is all chooseed for use to all bearing frames.
