Abstract
The invention relates to the technical field of truck equipment, in particular to a spoke bolt hole and center hole conical surface stamping die. An upper die plate is mounted on power equipment, and the power equipment is used for driving the upper die plate to move longitudinally; and an upper male die is fixed to the lower end of the upper die plate. A stripper plate is arranged below the upper male die; a spoke is arranged between the upper male die and the stripper plate; a male die fixing plate is arranged below the stripper plate; a bolt hole chamfering male die and a center hole chamfering male die are respectively fixed on the male die fixing plate; the upper end of the bolt hole chamfering male die and the upper end of the center hole chamfering male die penetrate through the stripper plate and cooperate with the lower end of the spoke; and nitrogen springs are fixed to the male die fixing plate, and the upper ends of the nitrogen springs cooperate with the lower end of the stripper plate. According to the spoke bolt hole and center hole conical surface stamping die, male die stamp forming of the die is utilized during bolt hole and center hole conical surface chamfering, meanwhile, the concentricity is basically unchanged, and therefore the subsequent machining procedure is omitted, the production efficiency is improved, and the production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of truck equipment, in particular to a stamping die for a spoke bolt hole and a conical surface of a center hole. Background technique [0002] The spoke manufacturing process of light-duty truck steel wheels generally includes: blanking punching, forming flanging, punching bolt holes and center holes, punching heat dissipation holes (some models design adjustment holes, adding punching adjustment hole process), countersinking bolt hole cones, Turning the center hole and outer diameter, etc., due to the flatness of the steel wheel of heavy trucks, the end face of the mounting surface needs to be turned. With the extensive development and application of urban logistics vehicles, the spoke structure of urban logistics vehicles is similar to that of light trucks, and the manufacturing process is also similar. This kind of heavy-duty steel wheel processing technology generally uses small rocker arm drilling to ...
