[0002] Cold-drawn round parts, also known as cold-drawn round parts or cold-drawn round steel, are round steels made by cold drawing. This type of steel usually has high strength, hardness and yield point, but its plasticity and toughness may be relatively poor. It has many excellent properties, such as good electroplating performance, can replace copper products to reduce product costs; easy cutting, can drill deep holes, mill deep grooves, etc.; processing efficiency is greatly improved compared to ordinary steel; the surface finish of the workpiece after turning is good.

[0003] If the polished round parts are not properly stored after production or during transportation, they may bend. This bending will change the original force relationship of the polished round parts, thus affecting their performance in use. Therefore, for the polished round parts that have been bent, calibration must be performed. There are many straightening machines on the market, but in order to better meet the needs of polished round parts calibration, this solution specially designs a special polished round parts calibration device. .

[0026] During specific use, the moving plate 3 drives the slider 6 to move inside the slide groove 7 through the bottom block 5. At this time, under the restriction between the two groups of sliders 6 and the slide groove 7, the movement trajectory of the moving plate 3 will remain stable.

[0027] Preferably, one end of the cushion strip 12 passes through the central opening of the notch 4, and the side surface of the slider 6 is a semicircular structure.

[0028] During specific use, when the moving plate 3 moves, it will pass through the pad strip 12, and then the moving plate 3 can drive the light-drawing round piece on the pad strip 12 to move.
