Introduction to Automatic Straightening Machine

The automatic straightening machine is an advanced device designed to detect and correct bends or deformations in shaft products that occur after heat treatment. It is a high-tech solution that integrates mechanical, electrical, hydraulic, pneumatic, and computer control systems.

Known for its high measurement accuracy, fast production cycles, and adaptability to different workpieces, this machine can measure the radial runout of circular sections, D-type sections, and the pitch circles of gears or splines of shaft workpieces with precision.

The automatic straightening process begins with the active and driven rotary centers clamping the workpiece. The active rotary center, powered by a speed-regulated motor, rotates the workpiece and transmits it to the driven rotary center.

Simultaneously, a measuring device attached to the movable support detects the total runout (TIR) of the workpiece. A photoelectric encoder on the driven rotary center determines the direction of the runout. Using this data, the computer identifies the workpiece's maximum bending position and direction.

It then commands the machine to stop with the maximum bending point facing upward and calculates the required correction based on the TIR amplitude and set parameters. The PLC system manages every aspect of the process, including clamping, support position, workpiece table movement, and punch feeding, ensuring precise and efficient straightening.

The shaft automatic straightening machine is widely used across various industries, especially in the automotive and machinery sectors, to correct deformations caused by heat treatment. Developed by the Changchun Mechanical Science Research Institute Co., Ltd., this machine straightens deformed points through pressure, offering high efficiency and stable performance.

The machine works by positioning rollers at a specific angle to the movement of the shaft. Two or three large active rollers, driven by a motor, rotate in the same direction, while smaller driven rollers on the opposite side rotate due to friction with the shaft.

The pressure on the product can be adjusted by moving these rollers. The number of rollers plays a critical role in the accuracy of the straightening process; more rollers typically result in greater precision. As the product moves through the rollers, it undergoes compression, bending, and flattening to achieve the desired straightness.

The automatic straightening machine boasts several advanced features that set it apart. It is designed to be user-friendly, with high measurement accuracy and adaptability to different workpieces.

The operator only needs to manage the loading and unloading of workpieces and starting the machine, while the machine automatically handles workpiece measurement, straightening point identification, pressurization, and curvature inspection. The automated process increases production efficiency and minimizes labor efforts while ensuring precise measurements.

Safety is a key consideration; the machine includes a maximum straightening limit to protect workpieces from breakage or cracking, thus ensuring operational safety. Additionally, it features a digital display showing the workpiece's bending amount and an intuitive bar graph display.

The fully Chinese human-computer interface is visually appealing and easy to learn. Upon completing the straightening process, the machine automatically determines if the workpiece meets tolerance requirements, providing both sound and light indications.

Furthermore, it is equipped with an extensive database that can store over 200 workpiece straightening parameters, accommodating various production needs. The operating software is based on a Windows platform and features a large-screen LCD for dynamic graphic displays of the correction process.
