Copper material straightening variable-frequency roller with brakes

Abstract

The invention provides a copper material straightening variable-frequency roller with brakes. The roller comprises a straightening wheel, a flywheel, at least two brake mechanisms, an electric controlcabinet, a variable-frequency motor, a flywheel, a speed sensor and a controller, the corresponding flywheel is coaxially connected with the straightening wheel and driven by the variable-frequency motor to rotate, and the at least two brake mechanisms are arranged outside the flywheels. The speed sensor is arranged on the flywheel, and the electric control cabinet is electrically connected withthe variable-frequency motor. Each brake mechanism comprises a compression roller assembly, a fixing plate and a pushing device, two compression rollers are arranged on the compression roller assembly, the pushing device is fixed to one side of the fixing plate, and a telescopic shaft of the pushing device is fixedly connected with the compression roller assembly. The speed sensor, the pushing device and the electric control cabinet are all electrically connected with the controller. The correspondingly flywheel is coaxially arranged on the straightening wheel, so that the rotation inertia ofthe straightening wheel is increased, the rotation of the straightening wheel is more stable, and the straightening effect is improved. The brake mechanisms are arranged on the peripheries of the flywheels and controlled by the controller, resistance can be applied to the flywheels during deceleration, deceleration of the flywheels is accelerated, and the straightening effect is guaranteed.

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...

Problems solved by technology

[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
