Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary tools for manufacturing bearing steel balls, and in particular relates to an auxiliary device for manufacturing precision bearing steel balls. Background Art

[0002] Ball blank forming → ring band removal → rough grinding → soft grinding → heat treatment → ball blank forming → polishing (or filing → soft grinding) → hard grinding → fine grinding → fine grinding (or polishing) → super fine grinding. Detailed production process of steel balls: 1. Wire drawing: Use a wire drawing machine to stretch the wire to the required wire diameter; 2. Cold heading (forging): Place the drawn wire into a steel ball cold heading machine, and use the steel die in the machine to forge it into a ball embryo; 3. Polishing: The two cast iron grinding ball discs in the polishing machine pressurize and file the cold-forged ball embryos to remove the outer ring belt and two poles on the ball embryos; 4. Softening: The two cast iron grinding ball discs in the soft ball machine file the polished ball embryos to grind them into the required ball diameter and surface roughness; 5. Heat treatment: Put the balls into a heat treatment furnace for carburizing, quenching and tempering to make the balls have a certain carburized layer and hardness, toughness and crushing load; 6. Hard grinding: The grinding machine The grinding wheel disc will pressurize and grind the heat-treated ball embryo to remove the black oxide layer on the surface of the ball and correct the accuracy of the ball; 7. Fine grinding / polishing and cleaning: Fine grinding: Fine grinding the ball embryo in the fine grinding machine to make the ball reach the accuracy and finish required for the finished product; Polishing and cleaning: Pour the ball into the polishing drum and rotate it and use polishing cleaning agent and water to clean the ball surface to make it clean and bright; 8. Appearance selection: Use manual visual inspection to check whether there are any defects on the surface of the steel ball, and use a micrometer to measure the true roundness, batch diameter variation and surface roughness tester to detect surface roughness as the final inspection; 9. Packaging: Apply anti-rust oil to the steel ball / stainless steel ball / bearing steel ball and pack it in a carton or woven bag.

[0003] Among them, in the appearance selection, when using manual visual inspection to check whether there are any defects on the surface of the steel ball, the operation is mostly that the inspector holds a tray with several steel balls and shakes the tray at different angles.
