Fork correction device and method

By designing an automated fork straightening device, high-quality fork straightening is achieved by utilizing the residual heat of heat treatment and the thermoelectric effect of auxiliary current. This solves the problems of operator experience dependence in hot straightening and work hardening in cold straightening in existing technologies, thereby improving straightening quality and equipment lifespan.

AI Technical Summary

⚠Technical Problem

In existing technologies, hot straightening of forks relies heavily on operator experience, making it difficult to guarantee straightening quality, and cold straightening can easily lead to work hardening.

⚗Method used

Design a fork straightening device, including a first straightening part and a second straightening part. The device uses the residual heat of heat treatment and the thermoelectric effect of auxiliary current for straightening. It combines automated and intelligent straightening methods, and performs multi-point support straightening through the cooperation of the first pressure block, the second pressure block and the third pressure block. The auxiliary current is used to keep the straightening part within a suitable temperature range and reduce the straightening pressure.

🎯Benefits of technology

It improves the stability of fork straightening quality, reduces reliance on operator experience, avoids work hardening caused by cold straightening, extends the service life of components such as hydraulic cylinders, and improves the automation level of the straightening process.

Abstract

The application discloses a fork correcting device, which comprises a first correcting part and a second correcting part. The first correcting part comprises a first correcting part rack, and the first correcting part rack is provided with a first correcting assembly and a second correcting assembly. The first correcting assembly comprises at least two first pressing blocks. The second correcting assembly comprises at least one second pressing block and one fifth pressing block. The first pressing block, the second pressing block and the fifth pressing block are located at the same height. The second correcting part comprises a second correcting part rack and a third hydraulic cylinder for pushing the second correcting part rack to move horizontally towards or away from the first correcting part. The third pressing block and the fourth pressing block are movably connected with the second correcting part rack. By means of the heat treatment residual temperature and the auxiliary current heat effect, the device can realize the sequential or simultaneous heat correction of the horizontal section, the vertical section and the included angle of the fork. The device has low dependence on the experience of workers and high stability of the fork correction quality.
