Description
TECHNICAL FIELD
[0001] The utility model belongs to the coating thickness measurement technical field, concretely relates to titanium and titanium alloy wire rod coating thickness on -line measurement system. BACKGROUND
[0002] In order to adapt to the fastener continuous upsetting process, titanium and titanium alloy wire rod with dry film lubricating coating in coil is needed. The dry film lubricating coating of titanium and titanium alloy usually uses molybdenum disulfide, graphite, tungsten disulfide, disperses the lubricating material into phenolic resin, deionized water etc., and then adds dispersing agent, leveling agent, thickening agent, defoaming agent and other surface additives to obtain coating liquid. The titanium and titanium alloy wire rod is coated with coating, usually adopts through type dip coating, and then is dried, wound and solidified on line.
[0003] The dry film lubricating coating of titanium and titanium alloy is generally less than 3 microns, the coating is too thin, the lubrication and load resistance are insufficient, and the upsetting process can cause the rod of fastener to be scratched. The dry film lubricating coating of titanium and titanium alloy is generally more than 25 microns, the coating is too thick, and the upsetting process can easily cause the coating to fall off in the mold, causing the rod of the subsequent upset fastener to be scratched due to the accumulation of the coating. Therefore, the titanium and titanium alloy coil wire rod for fasteners needs to control the thickness of the dry film lubricating coating within a certain range, and the coating thickness of the whole coil wire rod needs to be accurately measured and fed back to the coating machine in real time to adjust the coating winding speed and heating power.
[0004] The coating thickness detection usually adopts instruments or equipment to determine that it meets the standard requirements according to the detection method. GB / T13452.2-2008 "Determination of Film Thickness of Paint and Varnish" specifies the measurement methods of wet film coating, including mechanical method, micrometer measurement, comb rule and wheel rule measurement. However, these methods cannot be applied to the on-line coating measurement and on-line coating thickness control of titanium and titanium alloy coil wire rod. The magnetic induction thickness measurement needs the base body to be magnetically conductive, and titanium and titanium alloy are non-ferromagnetic materials, so this method cannot be applied. The ultrasonic thickness instrument cannot measure the coating thickness of 3 microns to 12 microns. The eddy current thickness probe or probe can affect the surface of the coated wire rod, and the coating wire rod cross section has curvature. It is relatively difficult to set the calibration and curvature compensation for different specifications of wire rod, which affects the coating thickness detection accuracy. The metallographic method can only detect the coating thickness of the wire rod cross section, and cannot measure the coating thickness of the whole coil wire rod. UTILITY MODEL CONTENTS
