An Ultrasonic Roller Structure for Rebar Rolling

Abstract

The invention discloses an ultrasonic roll structure for threaded steel rolling, comprising a roll and a support wheel, the support wheel is hollow inside, a hollow support shaft is connected to one axial end of the support wheel, an ultrasonic transmitter is installed at the inner bottom of the support wheel, and the roll There is a circular groove inside, the axial end of the roll is coaxially connected with the driving shaft, the supporting wheel is coaxially assembled in the internal circular groove of the rolling roll and cooperates with the relative rotation between the rolling rolls, the supporting shaft connected with the supporting wheel is from the shaft without the driving shaft installed on the rolling roll out to the other end. The invention can continuously form the ultrasonic interference to the rolled piece, and further improve the grain refinement efficiency of the rolled piece.

Description

technical field [0001] The invention relates to the field of thread steel rolls, in particular to an ultrasonic roll structure used for thread steel rolling. Background technique [0002] The rolling of the rebar needs to be carried out by a rolling mill, and the rolling of the rolled piece is realized by the roll inside the rolling mill. In order to promote nucleation and achieve grain refinement, some rolls are integrated with an ultrasonic device, and ultrasonic waves are formed by the ultrasonic device during the rolling process to promote grain refinement of the rolled piece. For example, the Chinese patent No. 201610202010.2: A new type of ultrasonic casting and rolling machine for preparing magnesium alloy slabs, which discloses a rolling mill that uses ultrasound to promote grain refinement. The device rotates with the roll as a whole, but in fact, the rolling effect is only performed when the roll is in contact with the rolling piece. Therefore, the ultrasonic devi...
