[0058] Example 1
[0059] A method for forging a TC4 cross shaped wing plate tibial tray artificial joint implant, comprising the following steps:
[0060] Step 1. Blanking, select φ40mmTC4 bar with a length of 39.4mm, the lower end face of the bar after blanking should ensure that there is no obvious saw or knife mark on the end face, and the lower end of the bar should be chamfered, and its bevel size should be 2x45 °~3x45°mm;
[0061] Step 2, surface treatment, surface treatment, remove cutting fluid, burrs, tool marks and other marks on the surface of the bar through steel sand shot blasting and polishing;
[0062] Step 3, spraying, spraying an anti-oxidation coating on the surface of the bar, heating the bar at a temperature of 100 ° C for 60 minutes, and taking out the glass protective lubricant for direct spraying of the precision forging process, the thickness of the anti-oxidation coating is 0.04mm on one side;
[0063] Step 4, extrusion, put the bar material in ste...
