Description

Technical Field

[0001] The present invention relates to the technical field of wire processing, and particularly to a wire straightening device and its process. Background Art

[0002] Due to its high strength and light weight, wires are widely used in many fields such as bridge construction, aircraft manufacturing, and mechanical transmission. Their shape accuracy directly affects the structural performance and service life. A wire straightening device ensures that the wire is straight or in the required curve, avoiding the influence of bending on strength and stiffness, and restoring the precise shape when necessary to meet the design requirements.

[0003] For example, the patent application No. CN201720905988 discloses a wire straightening device, which includes an upper main body, a lower main body, a rotating column, a bearing, a rotating shaft, a hand crank, a connecting plate, a fixing bolt, and a screw hole. Two rotating shafts are installed on the front side of the upper main body, and hand cranks are connected to the outer sides of the rotating shafts. A rotating column is integrally formed on the front side of the lower main body, and the bearing is installed on the rotating column. The bearing is tangent to the adjacent rotating shaft in the vertical direction. Connecting plates are integrally formed on the left and right sides of the lower main body, and screw holes are opened in the upper and middle parts of the connecting plates. The upper main body is installed between the two connecting plates through fixing bolts. In this device, the design of the upper main board with adjustable height can meet the straightening of wires with different diameters. The hand-operated rotating shaft pushes the wire to move, so that the wire is straightened under the force between the bearing and the rotating shaft. The grooves on the bearing and the rotating shaft ensure the walking track of the wire. However, when the annular groove on the bearing needs to be matched with wires of different diameters, the bearing needs to be replaced to make the annular groove on the bearing match the wire diameter, and the operation is relatively cumbersome.
