(2) In a rotating wheel type metal extrusion molding device that supplies powdered raw material to the material extrusion path formed between a rotating wheel and a stationary shoe, and extrudes it from holes formed in the shoe to form metal, A seal part is provided upstream in the rotational direction of the material supply hole opened in the shoe toward the groove of the wheel, the material supply hole is opened in a passage downstream in the rotational direction of the seal part, and the material supply hole and the suction side duct of the vacuum pump are provided. A rotating wheel type metal extrusion molding device characterized by having an airtight material supply tank interposed therebetween. 3. Detailed Description of the Invention Jin's invention relates to a rotating wheel type metal extrusion molding apparatus. Conventionally, a method has been adopted in which a shoe is attached to a rotating wheel having a groove on the outer periphery, a metal raw material is supplied to an extrusion passage formed by the shoe and the groove, and the metal is extruded through a hole formed in the shoe. There is. When extrusion molding is performed by supplying powdery raw materials using this method, the problem is that the air present between the powdery raw materials appears as bubbles during extrusion molding and is contained in the metal, resulting in a decrease in the quality of the molded product. It is what happens. This invention aims to improve the above points:. ′″-ai″″″″・l)m# Near F'317)”2
An object of the present invention is to provide a rotating wheel type metal extrusion molding apparatus that does not cause K in the metal due to grooves in the rotating wheel, and does not cause deterioration in the quality of molded products. A sealing portion is provided upstream in the rotational direction of the material supply hole opening in the shoe toward the shoe, and a suction side duct of the vacuum pump is communicated with a passage downstream in the rotational direction of the sealing portion. The present invention is characterized in that an airtight material supply tank is interposed between the material supply hole and the suction side duct of the vacuum pump.The invention will be described in detail below based on the embodiments shown in the figures. In the figure, l is a rotating wheel, and 2 is a fixed shoe.The rotating wheel l is a disc-shaped member, and its outer peripheral surface 12
A groove 11 having a U-shaped cross section is formed in. The shoe 2 is attached to the rotating wheel 1, and a material passage 3 is provided between the groove 11.
It is a member that forms the. Therefore, one side surface of the rotary wheel 1 forms an arc 21 with a diameter equal to that of the outer circumferential surface 12 of the rotating wheel 1. This arcuate surface ・Protrusion 31 on i. Material supply hole 3'11゜locking step 33. Annotation 34. A scraper 35 is formed corresponding to the groove 11. First, the material supply hole 32 is a hole that penetrates the arcuate surface 21 of the shoe 1 from the opposite side. A protrusion 31 is formed on the upstream side of the material supply hole 320 in the rotational direction of the rotating wheel 1 . The shape of the protrusion 31 serving as a sealing portion is the same shape as the cross-sectional shape of the groove 11 and is slightly smaller in size, and is designed to have a gap large enough to prevent the feed material from entering the groove 11. Supply hole 320 rotation Rotation wheel 1 Outward downstream side has groove 11
Correspondingly, the depth of the groove 11) is low, and a step 33 is formed which is also smaller than the width of the groove 11. At the end of the step 33, an apartment 34 having the same cross-sectional shape as the groove 11 is formed. A die 36 is embedded in the upstream side of the apartment 34 in the direction of rotation of the rotating wheel 10, and a hole 39 is formed to pass from the center of the die 36 to the opposite side. - A groove 1 is provided upstream of the protrusion 31 in the direction of rotation of the rotating wheel 1.
A scraper 35 is formed on the 1 side = scraper 35
is formed to protrude at an acute angle toward the upstream side in the rotational direction of the rotary wheel 1. The shape of the tip of the scraper 35 is such that it can scrape off a portion of the gap formed in the groove 11. An intake hole 37 is opened between the scraper 35 and the protrusion 31 and communicates with the opposite side. The airtight material supply tank 4 is attached to the material supply hole 32 so as to communicate therewith. The airtight material supply tank 4 contains a powdery material 5,
This is a material supply tank sealed from the outside world. To explain the operation of the rotating wheel type metal extrusion molding apparatus configured as above, both the airtight material supply tank 4 and the intake hole 37 are connected to the suction side duct 61 of the vacuum pump 6. At the same time as the metal molded product 8 is rotated and pushed out from the hole 39 of the shoe 2, the vacuum pump 6 is activated to start degassing. Airtight Wag4! , the stirrup 1i4 communicates with the material supply hole 32 and the extrusion passage 3, so that the air inside the powder material 5 is evacuated from the suction side duct 61. Furthermore, the air in the passage 3 is prevented from suctioning particulate material by the protrusion 31, and is communicated with the suction hole 37 and the suction side duct 61 of the vacuum pump 6, so that the air in this space is also degassed. Ru. Furthermore, when extruding the metal molded product 8, burrs 10 are formed on the inner peripheral surface of the groove 11 and the outer peripheral surface 12 of the rotary wheel 1 (the fourth
), the groove 1 is removed by the scraper 35 in this paris 10.
Only the part 10 attached to the inner circumferential surface of the rotary wheel 1 is cut, and the part 10 attached to the outer circumferential surface 12 of the rotary wheel 1 at a 4° angle is left as is. (Figures 5 and 6) Rotating wheel 1 by this Paris 10
The gap between the outer circumferential surface 12 of the shoe 2 and the shoe 2 is eliminated to prevent air from entering the extrusion passage 3 from there. (FIG. 7) Furthermore, various embodiments of the present invention are conceivable, but for example, as shown in FIG. By doing so, it is possible to perform the paring treatment well, and of course, it is expected that the sealing effect will be further improved. Further, the sealing portion is not limited to the projection 31 of the previously used embodiment, but the groove 11 is used to seal the upstream side of the extrusion passage 3. 4', various shapes can be considered, such as a protruding shape that is long in the direction of the groove 11. Since the present invention has the above configuration, it is possible to degas the air in the powder material, eliminate air bubbles in the metal molded product, and produce a high quality molded product. By degassing the air inside, deaeration can be made more complete.
