Description

510833 V. Description of the invention (1) [Technical Field] The present invention relates to a method for fixing a partition plate of a container, and more particularly, the present invention relates to a method for fixing a partition plate with a vertical cylinder wall container and a device thereof. [Previous technology] As shown in FIG. 4, it is a cross-sectional view of a conventional tube 7 with a partition plate 8. Generally, the three sides of the partition plate 8 are welded to the inner wall and the bottom surface of the tube using a wheel welding method. Then, the two corners of the bottom of the partition plate 8 and the tube are soldered with tin, and the bottom edge is welded (if the ring is not in place) so that there is no gap between the two spaces separated by the partition plate 8. However, because the melting point of tin itself is not high, if Lutong 7 is burnt, the disadvantage of tin melting is likely to occur. Even if φ food is heated in Lutong 7, the molten tin will affect the food even more. Safety and human health. In order to solve the foregoing problem, the inventor of the present case provides a new method, please refer to FIG. 5a, which uses a one-round welding method to finally install a partition plate 8 on the tube 7, which has a circular arc at the bottom. The segment 71 can be rolled over by the electrode wheel 9 of the wheel welder, and the partition plate 8 is formed with a bent portion on both sides and the bottom edge by means of punching. The bottom portion of the bent portion has a circle on each side. The arc edge 8 1 corresponds to the arc segment 7 1 of the Lu tube 7 so as to completely fit the inner wall of the Lu tube. And when the partition plate 8 is punched, creases will be generated at the arc edges 81 at the junctions of the sides. Therefore, the two corners of the partition plate 8 must first be cut to a predetermined portion to make the circle formed after punching. The arc edge 8 1 does not have too many creases, but because of this, the width of the arc edge 8 1 is narrower than other parts. In fact, the width of the arc edge 8 1 is only about

Page 4 510833 V. Description of the invention (2) 20 ~ 30% of the width of the straight section of the bending part. Therefore, as shown in Fig. 5c, when the electrode wheel 9 passes the arc edge 8 1, it will partially touch the arc segment 7 1 of the tube 7, and because the arc edge 8 1 and the arc segment 7 The height difference formed by the thickness of one separator 8 makes the current of the electrode wheel 9 completely concentrated on the arc edge 81, and the contact between the electrode wheel 9 and the round fox edge 81 is only a small area linear, Therefore, if the current is completely concentrated in this small range, the i arc is too large, and a lot of sharp objects formed by welding are formed on the arc edge 8 1 (Figure 5 b). Therefore, after the wheel welding is completed, it needs to be ground again. Flat. The treatment makes the surface of the round solitary edge 8 1 smooth and confusing. Furthermore, as shown in FIG. 6, since the minimum specification of the radius of the electrode wheel 9 of the wheel welder is 20 mm, the radius of the circular arc segment 71 must be greater than 2 ψ 0 mm. When the radius of the arc segment 71 does not meet the condition that π is greater than 20 mm π, the electrode wheel 9 cannot roll over the arc edge 8 1, so that the electrode wheel 9 is welded with the arc edge 81 of the separator 8. Therefore, these problems and disadvantages mentioned above must be resolved. [Objective and Effect] The main purpose of the present invention is to solve the above-mentioned problems and provide a method for fixing a partition plate with an upright cylinder wall container. This method does not require soldering with tin, and can avoid the dangers that are easily caused by the problem of tin itself. . Another object of the present invention is to provide a method for fixing a partition plate of a container with an upright cylinder wall. This method does not need to weld the M-arc segment at the bottom of the container and the arc edge of the partition by means of wheel welding, so that it can prevent the Occurrence of most sharp objects on the edge of the arc. A second object of the present invention is to provide a container having an upright cylindrical wall.
