A copper straightening variable frequency roller with a brake

Abstract

The invention provides a copper material straightening variable frequency roller with brakes, comprising a straightening wheel, a flywheel, a brake mechanism, an electric control cabinet, a frequency conversion motor, a flywheel, a speed sensor, a controller, and the flywheel is coaxially connected with the straightening wheel The rotation is driven by a frequency conversion motor. There are at least two brake mechanisms, which are located outside the flywheel. The speed sensor is located on the flywheel. The electric control cabinet is electrically connected to the frequency conversion motor. There are two pressing rollers on the assembly, the pushing device is fixed on one side of the fixed plate, and its telescopic shaft is fixedly connected with the pressing roller assembly; the speed sensor, the pushing device, and the electric control cabinet are all electrically connected to the controller. In the present invention, a flywheel is arranged coaxially on the straightening wheel, which increases the rotational inertia of the straightening wheel, makes its rotation more stable, and is beneficial to improve the straightening effect; a brake mechanism is arranged around the flywheel, and controlled by a controller, which can reduce the speed during deceleration. Apply resistance to the flywheel at the same time, accelerate the deceleration of the flywheel, and ensure the straightening effect.

Description

technical field [0001] The invention relates to the field of copper processing, in particular to a copper material straightening frequency conversion roller with a brake. Background technique [0002] In the field of copper production, copper is often smelted into copper rods / bars, which are handed over to downstream enterprises for further processing. The continuous casting method is generally used in the production of copper rods / copper bars, and the copper rods / copper bars produced by the continuous casting method are often irregularly curved, which makes the initial production of copper rods / copper bars need to be straightened. . In the straightening process, since the feeding speed of the copper needs to be constantly adjusted to control the tension of the copper, a frequency conversion motor is often used to control the straightening wheel in the straightening field. For example, CN201720943366.4 discloses a steel bar straightening and cutting machine powered by a va...

[0003] However, in actual production, in order to make the transportation of copper more stable, a straightening wheel with a larger diameter is usually used, or a flywheel is added to one side of the straightening wheel to increase stability, which makes the rotational inertia of the straightening wheel larger. Therefore, the straightening wheel often takes a long time to decelerate, which not only prolongs the shifting time and leads to low production efficiency, but also causes poor straightening effect due to untimely shifting
