Description

Technical Field

[0001] The utility model relates to the technical field of straightening devices, in particular to a piston rod calendering straightening device. Background Art

[0002] The piston rod calendering and straightening device is a device specially used to correct the bending deformation of piston rods and other similar shaft parts. It is designed to eliminate the bending that may occur in the workpiece during production, transportation or use through precise mechanical force and hydraulic action, and ensure that its geometric size and shape meet the design standards. The working principle of the piston rod calendering and straightening device is based on the application of hydraulic or mechanical force. By precisely controlling the pressure on the workpiece, it gradually returns to the ideal straight line or cylindrical shape. These devices are usually equipped with sensors and control systems that can monitor the pressure and displacement during the straightening process in real time, thereby ensuring the accuracy and reliability of the straightening. The piston rod calendering and straightening device generally includes a straightening mechanism, a conveying mechanism, a collecting mechanism and other auxiliary mechanisms.

[0003] The straightened piston rod needs to be properly collected and processed. Most of the piston rod calendering and straightening devices in the prior art are not equipped with an automatic unloading mechanism. The straightened piston rod is directly transported out of the straightener and falls to the ground, which is prone to bending and damage again, resulting in a decrease in the overall equipment production quality and reducing the practicability of the device.
