Definitions

  • the present invention relates to a spin forming apparatus, which is used when spin forming while heating a material.
  • a material to be molded is set on a mandrel, and the material to be molded is rotated along with the mandrel, and is handled along the mandrel while being pressed by a pressing spatula. It is processed into a shape.
  • the present invention solves such conventional inconveniences, and even if a complicated shape or a quick processing is performed, the material to be molded is unreasonable. As a result, the material to be molded is It is an object of the present invention to provide a spinning molding device that is less likely to crack. Disclosure of the invention
  • a material to be molded is placed on a mandrel, the material to be molded is rotated by rotating the mandrel, and the rotating material to be molded is rotated by a pressing spatula.
  • a spinning molding apparatus that handles along the mandrel while pressing and pressing,
  • a heating means is provided on the pressing spatula, the heating means is movable in conjunction with the pressing spatula, and the material to be molded can be heated to a predetermined temperature by the heating means. Since it is a spinning molding apparatus, the heating means can heat only the working part of the pressing spatula during spinning molding, and can quickly and rationally mold the material to be molded into a complicated shape. is there.
  • FIG. 1 is a sectional view of the first embodiment. BEST MODE FOR CARRYING OUT THE INVENTION
  • S is a spinning molding device
  • 2 is a rotation shaft of the spinning molding device S.
  • the rotating shaft 2 is rotatable around the axis.
  • Reference numeral 3 denotes a mandrel, which is detachably fitted to the outside of the bearing shaft 2.
  • the peripheral surface of the mandrel 3 constitutes a mold part 3-1 for forming the wheel W for a vehicle by sliding.
  • 4 Wheels for steel vehicles Corresponding to the “material to be molded” of the present invention, which is installed on one surface of the mandrel and is sandwiched between tailstocks 5. Therefore, the vehicle wheel material 4 rotates in the same direction as the mandrel 3 rotates.
  • the wheel material 4 for a vehicle is made of a structure, and the disc portion 4 1 sandwiched between the mandrel 3 and the tail stock 5 and the rim material (see the phantom line diagram) 4 2 If the rim material 42 is pressed in the direction of the arrow by the pressing spatula 6 while the mandrel 3 is turned, the rim 42 1 is spun-formed.
  • Reference numeral 7 denotes a wrench (corresponding to “heating means” of the present invention) for heating the rim material 42.
  • the burner 7 is mounted on the pressing spatula 6 and moves in accordance with the movement of the pressing spatula 6. Therefore, the working part of the pressing spatula 6 can be locally heated.
  • the rim material 42 is preferably heated to about 300 by the burner 7.
  • the burner 7 To set the rim material 42 within the above temperature range (approximately 300-c), measure the temperature of the molded part of the rim material 42 using an infrared thermometer and perform feedback.
  • the heating power of the gas parner 7 can be adjusted according to the formula.
  • the Pana 7 is ignited and stopped and extinguished.
  • an artificial vehicle wheel material 4 is installed on the mandrel 3. After being clamped by the tail stock 5, the mandrel 3 is substantially omitted. Rotate at 30 ORPM. At this time, at the same time, the lamp is ignited and heating of the rim material 42 starts. Then, when the temperature of the rim material 42 reaches a predetermined temperature (approximately 300 ° C.), the rim material 42 is pushed in the direction of the arrow by a pressing spatula 6, and the vehicle wheel is rotated. Get W. After forming the vehicle wheel W, the rotation of the mandrel 3 is stopped. At the same time, the gas burner 7 is digested. Industrial applicability
  • the forming apparatus according to the present invention is useful as a means for quickly and rationally forming a complicated object into a complicated shape. Suitable for forming the rim part.
