Definitions

  • This invention relates to a spin molding apparatus, and more particularly to a spin molding apparatus which is used when a material is heated and spin-molded at the same time.
  • the spin molding is effected as follows.
  • a material to be molded is set on a mandrel, rotated together with the mandrel, and then pressed onto and squeezed along the mandrel by a pressure spatula as this material is rotated together with the mandrel, thereby spin-molding the material into a predetermined configuration.
  • the above-mentioned spin molding is one of molding processes utilizing the ductility of a material to be molded, it has such disadvantage as that where, for example, a material to be molded is required to be rapidly spin-molded into a complicated configuration, excessive stress is incurred to the material and as a result, cracks tend to occur in the material.
  • a spin molding apparatus in which a material to be molded is set on a mandrel, said material being rotated by rotating said mandrel , said rotating material being pressed onto and squeezed along said mandrel by a pressure spatula
  • a spin molding apparatus according to the present invention being characterized in that said pressure spatula is provided with heating means operatively connected thereto for joint movement, so that said material can be heated to a predetermined temperature with said heating means.
  • the heating means is capable of heating the pressure spatula only at an operating portion thereof during the spin molding operation, the material can be spin-molded into a complicated configuration rapidly and efficiently.
  • the apparatus can be made compact and the heating temperature can be adjusted with ease.
  • Fig. 1 is a sectional view of a first embodiment of the present invention.
  • the reference character S denotes a spin molding apparatus
  • the reference numeral 2 denotes a rotary shaft of the spin molding apparatus S.
  • the rotary shaft 2 is rotatable about the axis.
  • the numeral 3 denotes a mandrel which is removably fitted to the outer side of the rotary shaft 2.
  • the peripheral surface of the mandrel 3 forms a mold portion 31 designed for spin molding a wheel W for the use of a vehicle.
  • the numeral 4 denotes a wheel material (corresponding to the "material to be molded" of the present invention) for a vehicle which is made by casting.
  • the material 4 is set on one side of the mandrel 3 and clamped by a tail stock 5.
  • the vehicle wheel material 4 is rotated in the same direction as the mandrel 3 in accordance with the rotation thereof.
  • the vehicle wheel material 4 is formed by casting and comprises a disk portion 41 sandwiched between the mandrel 3 and the tail stock 5 and a rim material (see the imaginary line in Figure) 42.
  • a rim material 42 is squeezed, by a pressure spatula 6, in the direction as shown by an arrow as the mandrel 3 is rotated, a rim 421 is spin-molded.
  • the numeral 7 denotes a burner (corresponding to the "heating means" of the present invention) which is adapted to heat the rim material 42.
  • the burner 7 is installed on the pressure spatula 6 and moved in accordance with the movement of the pressure spatula 6.
  • the operating portion of the pressure spatula 6 can be locally heated.
  • the rim 421 is spin-molded, it is desirable that the rim material 42 is heated to approximately 300°C.
  • the temperature of the molding portion of the rim material 42 is measured by an infrared ray thermometer and the thermal power of the gas burner 7 is adjusted by a feedback system.
  • the burner 7 Upon start of the rotation of the mandrel 3, the burner 7 is ignited and upon stop of the mandrel 3, the burner 7 is extinguished.
  • the vehicle wheel material 4 is set on the mandrel 3 first. After the material 4 is clamped by the tail stock 5, the mandrel 3 is rotated at approximately 300 rpm. At that time, the burner 7 is ignited simultaneously and starts heating the rim material 42. When the temperature of the rim material 42 has reached the predetermined temperature (approximately 300°C ), the material 42 is squeezed in the direction as shown by an arrow, by the pressure spatula 6. As a result, the vehicle wheel W is obtained. After the vehicle wheel W is molded, the mandrel 3 is stopped rotation. At that time, the gas burner 7 is extinguished simultaneously.
  • the spin molding apparatus is useful as means for spin-molding a cast material into a complicated configuration rapidly and efficiently and particularly suitable for molding a rim portion of a vehicle wheel.
