Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a cypress ware used for cooking.

The present inventor has already published patent No. 970125 (Japanese Patent Publication No. 54-2928) and patent No. 1133108 (Japanese Patent Publication No.
No. 2134), etc., but the present invention is particularly applicable to Patent No. 113310.
This invention improves some of the drawbacks of the prior invention related to No. 8 and provides a process that makes assembly work easier, and thereby aims to further strengthen the mass production system and reduce costs. It is. The manufacturing method of the present invention will be explained step by step.

The inner wig metal 6 is iron-fitted toward the inner periphery of the wig metal 6 with its bottom surface 6' facing the upper surface 2 of the wig metal 3.

In such a conflict situation, needle line 5...

It should be noted that the bottom surface 6' of the inner wig 6 is not provided with any through holes. By the way, the above-mentioned inner wig gold 6
is one embodiment of the present invention.

That is, in consideration of cost reduction, instead of interposing the inner wig 6 and welding the needle wire proximal ends 5', 5' thereto, the inner wig 3 is directly connected to the inner wig from the circumferential surface of the outer wig 3. They may be fixed by spot welding toward the needle wire base end portions 5', 5'. 4. After fixing the needle wire base ends 5', 5', iron the pipe handle 8 of an appropriate length toward the wig metal 3.

When joining the pipe handles, one end 10 of the pipe handle 8 is applied to the lower peripheral surface 1 of the wig metal 3 and strong pressure is applied as it is, so that the pipe handle slides up the peripheral surface of the wig metal and stops. At this time, the end surface of the pipe handle and the top surface of the wig metal should be aligned. (See Figure 4) 5. After that, an appropriate amount of cement 9 is poured from the other end opening 10' of the pipe handle 8. Then, the cement 9 fills and fills the needle wire base end portions 5', 5', . . . inside the inner wig 6, and eventually dries. (See FIG. 5) 6. Finally, the cap 11 is crimped onto the other end row 0' of the pipe handle 8.

(See Fig. 6) The present invention thus provides a wig 3 in which the lower circumferential surface 1 is slightly narrowed inward and formed into an arc shape.
Each base end 5', 5' of a bent needle line 5......... is placed at a relative position of the through hole 4......... punched around the upper surface. . . . , insert one end 10 of the pipe handle 8 of an appropriate length onto the lower peripheral surface 1 of the wig metal 3, and apply strong pressure to the end surface of the pipe handle. Push it in until it lines up with the top surface of the needle wire and fix it, and then pour an appropriate amount of cement 9 from the end opening 10' of the pipe handle 8 to seal the base ends 5', 5', and 5' of the needle wires.
The manufacturing method for Nada Azusa ware consists of filling in the pipe handle, and finally fixing the cap 11 to the end of the pipe handle. Due to the special shape of Katsura-kin, the work of joint crimping can now be done smoothly and quickly, and the work of iron-bonding pipe handles to Katsura-kin, which was previously difficult, can now be carried out efficiently, reducing the welding process. The effect is clearly improved, and since the arc shape of the lower peripheral surface of the wig produces a springing effect, competitive adhesion with the pipe handle can be improved.Secondly, cement filling is also necessary. This makes it possible to securely fix the proximal end of the needle wire in essential parts, and thirdly, it has become possible to reduce costs by reducing the number of work processes as a whole, which has an extremely large effect. It is something.

Claims (1)

[Claims] 1. Insert each proximal end of the bent needle wire into the relative position of the through hole drilled around the upper surface of the wig whose lower peripheral surface is slightly narrowed inward and formed into an arc shape, and Apply one end of the pipe handle to the lower circumferential surface of the wig, push it in with strong pressure until the end surface of the pipe handle matches the top surface of the wig, and then secure the pipe handle through the opening of the other end of the pipe handle. A method for producing an agitator, which comprises pouring an appropriate amount of cement to fill the base end of the needle wire, and finally fixing a cap to the other end of the pipe handle.
