Uneven heat input during laser cladding of cylinders (especially thin-walled cylinder liners) can easily cause component deformation, resulting in excessive roundness and cylindricity of the repaired inner hole, making assembly impossible. Controlling deformation is the decisive factor for the success or failure of cylinder laser remanufacturing engineering.
We have developed a comprehensive deformation control scheme: 1 Fixture design: Copper or steel fixtures with circulating water cooling are used to quickly dissipate heat and provide rigid constraints for the cylinder to be repaired. 2. Scanning path optimization: Abandoning continuous spiral scanning, adopting the "segmented symmetrical scanning method", which divides the inner wall of the cylinder into several symmetrical areas and alternately fuses them to cancel out thermal stresses. 3. Process monitoring: Use non-contact laser displacement sensors to monitor cylinder deformation online, provide real-time feedback, and fine tune the scanning path.
Through the above measures, for hydraulic cylinders or compressor cylinders with a length of 1-2 meters, the roundness and cylindricity of their inner holes can be stably controlled within a tolerance range of 0.02mm-0.05mm after repair, fully meeting the requirements for direct precision honing and ensuring high quality and high pass rate of remanufactured products.
