Description

Detailed Description of the Invention (Object of the Invention) The present invention provides a mixed lamp unit that incorporates a continuous right-handed or left-handed twisted wing piece in a pipe, and by extruding it, the twisted wing pieces of the pipe can be combined with the twisted wing pieces of the pipe. The present invention relates to a method of manufacturing a mixed fly Azusa unit that is integrally molded at the same time, and an apparatus therefor.

(Prior art) Conventionally, in a mixing attenuator in which a right-handed or left-handed twisted wing piece is built into a pipe for mixing several types of fluids, etc., the pipe and the twisted wing piece are made separately, and then The twisting wing pieces were inserted into the pipe, and the joint surfaces were glued and crimped to fix the pipe and the twisting wing pieces, which required a large amount of man-hours.

In particular, when this mixing thickener is made of ceramics, if the pipe and twisted wing pieces are bonded together and then fired, the bonded parts tend to crack due to the difference in shrinkage rate during firing, resulting in a decrease in strength and damage. There were many. Additionally, if the adhesive oozes out from the bonding surface when the pipe and torsion blade are bonded together, it will solidify and create uneven surfaces on the smooth surfaces of the pipe and torsion blade, which will impede the smooth flow of fluids and mix them. Efficiency was reduced, and fluids often got stuck in the container and stopped flowing.
(Structure of the Invention) In order to eliminate the above-mentioned drawbacks, the present invention has a die attached to the tip of a nozzle connected to an extrusion processing machine, and a core metal having a semicircular cross section is placed relative to the die while maintaining a required gap within the die. A right-handed twisting rotor is attached to one end of the rotating shaft to which this core metal is attached, and the plastic material pressurized by the extrusion processing machine is applied to the twisting rotor and the plastic material is flowed into the flow. This is a method to manufacture a mixed torsion unit in which the torsion blades are integrally built into the pipe by rotating the torsion rotor blades together with the core metal and extruding the plastic material from the gap between the die and the core metal and the gap between both core metals. The embodiment shown in FIGS. 1 to 7 will be described.

As shown in FIGS. 1 and 2, the manufacturing device for the mixed fly frame unit W incorporating right-handed twisted wing pieces R includes a bearing plate 2 attached to a conduit 1 connected to an extrusion processing machine (not shown). Attach the nozzle 3 through the nozzle 3, and attach the die 4 to the tip of the nozzle 3. The rotating shaft 5 is aligned with the axis of the die 4 and supported on the bearing plate 2, and a torsion rotor 6 having a right-handed twisted curved surface 6a is attached to the end on the conduit 1 side. Core metal 7 with a semicircular cross section,
7 are mounted on the rotating shaft 5 so as to face the axis '0 of the die while maintaining a required gap a. The core bars 7, 7 and the die 4 are designed to maintain a required gap b depending on the wall thickness of the pipe P of the mixed rope frame unit W. On the other hand, the manufacturing device for the mixed flying unit W' that incorporates the left-handed twisted blade L has the torsion rotor blade 6 of the manufacturing device for the mixed flying unit W that incorporates the right-handed twisted blade R shown in FIG. As shown in FIG. 3, it has been replaced with a left-handed twisted rotor blade 6'. 6a' is a twisted curved surface.

In the embodiment, the two cored metals 7, 7 were provided so as to face each other to form two divided twisted wing pieces, but as shown in FIG. 4, the cored metals 7', 7', 7' Forming three twisted wing pieces with individual parts facing each other, as shown in FIG.

It is also easy to form divided twisted wing pieces. (Function of the Invention) To explain the function of the present invention with reference to FIG. The torsion rotor 6 comes into contact with the torsion curved surface 6a of the torsion rotor 6 to apply a rotational force in the S direction to the torsion rotor 6, thereby continuously rotating the torsion rotor 6 in the S direction.

The core metals 7, 7 connected to the torsion rotor blade 6 and the rotating shaft 5 rotate in the S direction together with the torsion rotor blade 6, and the plastic material M is formed between the gap a between the two core metals 7, 7, the die 4 and the core metal 7, 7 are simultaneously extruded from the gap b. The plastic material M extruded from the gap b is formed as a pipe P, and the plastic material M extruded from the gap a is twisted right-handed by the continuous rotation of the core metals 7, 7 in the S direction. The twisted wing pieces R are formed integrally with the inner circumferential surface of the pipe P, forming the mixed lamp unit W shown in FIG. On the other hand, in the device shown in FIG.
The plastic material M is applied to a and applies a rotational force in the t direction to continuously rotate the core metals 7, 7 in the t direction. The plastic material M is integrally extruded from the gap a between the core metals 7 and 7 into left-handed twisted winglets L onto the inner circumferential surface of the pipe P, and incorporates the left-handed twisted winglets L shown in FIG. This becomes a mixed rope Azusa unit W'.
In the thus obtained mixed light azusa units W, W', the right-handed twisted wing pieces R in the mixed fly azusa unit W and the left-handed twisted wing pieces L of the mixed light azusa unit W' have end faces perpendicular to each other. By connecting the ropes alternately with flanges, etc., as shown in FIG. (Effects of the Invention) In the present invention, the pipe and the torsion blades are extruded together while rotating the core metal by the flow of plastic material, so there is no joint surface between the pipe and the torsion blades, and the strength is increased. improved,
Many man-hours, such as inserting and gluing twisted wing pieces into a pipe, as required in the past, can be omitted.

Moreover, even when made of ceramics, cracks do not occur due to differences in shrinkage rate during firing, and the yield of the product is high and it can be manufactured at low cost. In addition, since there is no leakage of adhesive or the like, the flow of fluids, etc. is smooth, and the mixing ability is improved.
Furthermore, since this device does not require any driving section for rotating the core metal, the device is extremely simple and has extremely great effects.
