The Production Process of Steel Wheel Spokes

Step 1: Leveling: the process of leveling the incoming coil sheet;

Step 2: round off: pass the leveled sheet blank through the hydraulic press and the die, and punch out the round blank of a certain size;

Step 3: punching the pre-hole: punch out the pre-hole in the center of the round blank on the punching machine for subsequent positioning;

Step 4: Spinning: locate the center pre-hole, and spin the round blank into a certain shape of the spoke blank through the spinning machine;

Step 5: Shaping: Shaping the mounting surface of the spoke blank through a press and a die to make the flatness of the mounting surface meet the specified requirements;

Step 6: Combined stamping: the process of punching out the center hole and bolt hole of the spoke blank at the same time through the press and die;

Step 7: Punching holes: Punch out a specified number of ventilation holes on the spoke blank through a die with an indexing device on the punching machine;

Step 8: Squeeze the air hole: the process of extruding the punching burr formed by punching the air hole of the spoke blank through the die on the punching machine;

Step 9: flat end face: mainly to flatten the end face of the spoke, so that the height of the spoke meets the requirements, and it is also conducive to subsequent welding;

Step 10: Hole in the car: It is mainly to finish the center hole of the spoke on the lathe to the specified size through the tire;

Step 11: Flattening: Shape the mounting surface of the spoke blank through a press and a die to make the flatness of the mounting surface meet the specified requirements;

Step 12: whole outer diameter: the process of finishing the outer diameter of the spokes through a press and a mold;

Step 13: finishing screw holes: the process of finishing the spoke bolt holes is generally carried out on a multi-head drill, and the geometric size and accuracy of the bolt holes can meet the specified requirements by reaming and scribing.
