Tension damper

Abstract

The invention provides a tension damper. A balance bar is rotatably mounted on a balance base. An angle sensor used for detecting the rotation angle of the balance bar is arranged on the balance base.With the rotation axis of the balance base as a boundary, a damper body is arranged at one end of the balance bar and is used for providing advancing resistance for a wire or strip; and a sliding block device is arranged at the other end of the balance bar, and the position of the sliding block device can be adjusted along the balance bar. According to the tension damper, the tension applied to the wire or strip can be accurately adjusted through the structure of the balance bar, and thus, the tension damper can be applied to a wire or strip production line with a high precision requirement;and the resistance of the wire or strip can be controlled to keep the advancing speed of the wire or strip constant while the tension is controlled, the tension borne by the wire or strip is kept constant, and thus, the production quality of high-precision wires or strips is improved.

Description

technical field [0001] The invention relates to the field of tension dampers, in particular to a tension damper with adjustable damping force. Background technique [0002] The winding process is often involved in spinning, wire or strip production. In this process, the winding device is driven to rotate by the driving device, but as the diameter of the winding package increases, the pulling force applied by the package to the wire or strip A change occurs, usually increasing, which causes quality problems in the wire or strip, such as the wire or strip being stretched. A tensioner is usually used to keep the tension on the wire or strip constant. [0003] Known tensioners commonly used in spinning, wire or strip production usually use gravity or spring tensioners. The problem with these tensioners is that tension adjustment is relatively difficult. [0004] In the production process, the winding operation is involved. In order to ensure the uniform winding of the wire or ...

Problems solved by technology

Chinese patent document CN107324144A describes a tension adjustment device, which can adjust the width with a large damping force, but the installation method of this scheme can only maintain the structure of the vertical axis, and is affected by factors such as eddy currents and evaporation, and the damping force is limited. Output control curve fails to maintain linearity
