Definitions

  • the present invention relates to a supply method and a supply apparatus of a semi-solid metal.
  • JP-B2-3211754 discloses a method of preparing a semi-solid metal (slurry) in a solid-liquid coexisting state by cooling a metal in a molten state of aluminum or magnesium, or alloys of these or the like and producing a metal molded product by using the semi-solid metal.
  • a molding apparatus including an injection sleeve formed with an opening portion, and a plunger provided progressively/regressively at inside of the injection sleeve. Specifically, first, a semi-solid metal is supplied from the opening portion to the injection sleeve. Next, the semi-solid metal supplied to the injection sleeve is extruded by the plunger to be injected into a die connected to the injection sleeve. Next, the semi-solid metal injected into the die is cooled to solidify the semi-solid metal.
  • a metal molded product in accordance with a shape of an inner portion of the die can be fabricated as described above.
  • a viscosity of the above-described semi-solid metal is higher than that of the metal in the molten state. Therefore, a force which is going to maintain a current shape is large. Therefore, when a press force is applied in extruding the semi-solid metal by the plunger, the semi-solid metal is applied with a stress in a direction opposed to a direction of the press force to maintain the current shape. Therefore, the semi-solid metal is squeezed by the press force and the stress to considerably deform, and there is a case of jumping out from the opening portion of the injection sleeve to outside. As a result, a step of removing the jumped semi-solid metal is needed to pose a problem that a production step cannot be made to be efficient.
  • One or more embodiments of the present invention provide a supply method and a supply apparatus of a semi-solid metal capable of preventing the semi-solid metal from jumping out.
  • the supply method is provided with a first step of producing the a semi-solid metal from a molten metal at an inner portion of a vessel in a shape of a cylinder, and a second step of supplying the semi-solid metal contained in the vessel to the inner portion of the injection sleeve by inserting a front end of the vessel into the opening portion of the injection sleeve by a predetermined angle.
  • the semi-solid metal is injected to a side in a direction of advancing the plunger more than at the opening portion.
  • the front end of the vessel is inserted into the opening portion of the injection sleeve by the predetermined angle and the semi-solid metal is injected to the side in the direction of advancing the plunger more than the opening portion by way of the front end of the vessel. Therefore, even when the semi-solid metal is extruded by the plunger, the semi-solid metal can be prevented from jumping out from the opening portion.
  • a gutter may be provided on a front end side of the vessel, and at the second step, a front end of the gutter may be inserted into the opening portion by the predetermined angle and the semi-solid metal may be injected from the front end of the gutter.
  • the front end side of the vessel is provided with the gutter, the semi-solid metal is injected from the front end of the gutter, and therefore, the semi-solid metal can smoothly be supplied to the inner portion of the injection sleeve by increasing a flow rate of the semi-solid metal.
  • the gutter may be configured to be attachable and detachable to and from the vessel.
  • the semi-solid metal When the semi-solid metal is produced from the molten metal at the inner portion of the vessel, it is necessary to cast the molten metal to the vessel and stir the molten metal. However, when the vessel is provided to the gutter, the molten metal is stirred by inserting a stir rod from the front end of the gutter, and therefore, it is difficult to uniformly stir the molten metal.
  • the gutter does not constitute a hindrance when the moltenmetal is stirred and the moltenmetal can uniformly be stirred.
  • the supply apparatus in a supply apparatus of a semi-solid metal of the invention for supplying the a semi-solid metal to a molding apparatus having an injection sleeve formed with an opening portion, and a plunger progressively/regressively provided at an inner portion of the injection sleeve, the supply apparatus is provided with a vessel in a shape of a cylinder containing the semi-solid metal, a carry arm for grabbing to move the vessel, and a controlling apparatus for controlling the carry arm.
  • the control apparatus inserts a front end of the vessel into the opening portion of the injection sleeve by a predetermined angle and injects the semi-solid metal contained in the vessel on a side in a direction of advancing the plunger more than at the opening portion.
  • the carry arm may include a gutter capable of being connected to the vessel, and the controlling apparatus may connect the gutter to the vessel, insert a front end of the gutter into the opening portion by a predetermined angle and inject the semi-solid metal from the front end of the gutter.
  • the gutter can be connected to the vessel by grabbing the vessel by the carry arm, and therefore, an effect similar to the above-described effect is achieved.
  • the gutter may be constituted by a shape of a groove.
  • the gutter is constituted by the shape of the groove, and therefore, in comparison with the case in which the gutter is constituted by a shape of a cylinder, the atmosphere is easy to flow smoothly to the inner portion of the vessel and the semi-solid metal can smoothly be injected from the vessel.
  • the front end of the vessel is inserted into the opening portion of the injection sleeve by the predetermined angle and the semi-solid metal is injected to the side in the direction of advancing the plunger more than at the opening portion by way of the front end of the vessel. Therefore, even when the semi-solid metal is extruded by the plunger, the semi-solid metal can be prevented from jumping out from the opening portion.

  • the carry arm 13 is a movable arm of an articulated robot a whole content of which is not illustrated, and the articulated robot includes 6 axes of movable shafts and includes an arm 137 and a hand 136.
  • the hand 136 is pivoted centering on a rod 138 relative to the arm 137 by way of a rod 138, or relatively rocked by constituting a base point by a base end side of the rod 138.
  • the hand 136 is provided with a gutter 131 an upper half of which is opened.
