Technical field

The present invention relates to a container of articles, and more particularly to a nodule, and a method of processing the same. Background technique

At present, the objects on the market are cylindrical, and the cylindrical surface is smooth and easy to slip.

Referring to Fig. 1, there is also an outer arched vessel which is also smooth and smooth due to the change of the side wall, and is not convenient to handle.

There are only a few simple structures in the market, which are in a single form and cannot promote consumers' desire for consumption. Summary of the invention

The technical problem to be solved by the present invention is to provide an inner arched nodule and a method of producing the same. In order to solve the above problems, the present invention adopts the following technical solutions:

A node device is formed by interconnecting a plurality of hollow tubes. The hollow tubes are made of stainless steel, and the side walls of each of the hollow tubes are inwardly arched and gradually expanded toward both ends.

The upper port and the lower port of each of the hollows are equal in diameter, and an inner arch shape is formed which is vertically symmetrical with the intermediate recessed portion as an axis.

The hollow port of each of the hollow tubes has a large diameter, the upper port has a small diameter, and the connected ports have the same caliber.

The bottom of the node has an inclined bracket, and the upper surface of the inclined bracket is inclined. A U-shaped inner liner is inserted into the node.

A method of processing the above-described nodule sub-step comprises the following steps:

1), first roll the stainless steel sheet into a hollow cylinder, and weld the two ends of the butt joint;

2) inserting two punches into the two ports of the hollow body respectively, and respectively pressing the upper and lower end faces of the hollow cylinder to the middle to form a two-port everted, inner concave inner arched single-joint ;

3) Repeat the steps 1) and 2) above according to the required number of sections;

4), the formed end face of the multi-section inner arched single-joint uniform radius is welded to form a multi-section inner archer;

5), welding the bottom portion of the multi-section inner arch;

6), grinding and polishing the above-mentioned multi-section inner arch.

The hollow cylinders enclosed by the steel sheets in the step 1) have the same cross-sectional area, and are inserted by the same punch at the two ports of the hollow cylinder and extruded at the same force to form an intermediate concave, and the symmetric structure gradually expands toward both ends.

In the above step 1), the steel sheet is wound into a plurality of hollow cylinders having different sectional areas, and step 2) applying different expansion forces at each port of each hollow cylinder to form a small upper diameter, a large diameter of the lower port, and a concave inner wall Inner arch shape.

The beneficial effects of the invention are as follows: The inner arched joint device provided by the invention has the anti-slip effect, and overcomes the defect of single product structure on the market, and the processing method of the knotter can be realized only by the convex mold. There is no need for a die, which greatly reduces the friction of the material during the forming process, so that the product is not broken, wrinkled, scratched, etc., and the produced blank (semi-finished product) has no deformation, high stability, argon. Arc welding is continuously welded into products to provide conditions. DRAWINGS

The present invention will be further described in detail with reference to the drawings and specific embodiments.

Example 1

The invention relates to a node device firstly rolling a square stainless steel piece 10 into a hollow cylinder 11 and welding the two ends of the butt joint by argon arc welding; placing the processed hollow cylinder 1 on the punch 12 at one end of the punching machine 1 1 , the machine is started, and the punch 12 at the other end punches the hollow cylinder 1 1 downward, and the same force is applied to the two ports to form an inner arched single-joint with the diameter of the two ports becoming larger and outwardly turned out. 13. Since the two ports exert the same force, the two ports are equal in diameter and are axisymmetric with the intermediate recessed portion. Refer to Figure 2 and Figure 3 for the specific structure.

As needed, a plurality of such single-section vessels are machined and welded in sequence to form a multi-section internal changer. The U-shaped inner tube 14 shown in FIG. 4 is placed in the multi-section inner shape changer, and the open end thereof is welded with the open end of the multi-section inner arc-shaped hollow cylindrical body, and the multi-section inner arch shape is given. The hollow cylinder is welded to the bottom, polished and polished to form the inner arch-shaped container. The formation process of the aforementioned stator sub-section is shown in FIG. The formed nodule is sub-complete, beautiful and non-slip.

Example 2:

A reclining bracket 15 is arranged at the bottom of the above-mentioned notch, the side wall of the inclined bracket is long, the side wall of one side is short, the upper surface is inclined, or the triangular shape of the inclined bracket 15 is formed as shown in FIG. 5, and the bottom surface is small in curvature. The curved surface can sit on the plane. This italic structure looks more aesthetic and artistic.

Example 3:

A plurality of steel sheets 20 of equal width and unequal width enclose a plurality of hollow cylinders 21 having different cross-sectional areas. A different expansion force is applied to the two ports by the punch 22 to form an inner arched vessel 23 which is recessed in the middle of the side wall having a small upper end port and a large lower end port. According to the method, the plurality of hollow columns are Body 21 is extruded. The upper and lower port diameters of the single-member formed by the large-section column are relatively larger than the upper and lower ports of the column having the smaller cross-sectional area, and the multi-section inner arches are sequentially connected to form the inner arch with the largest bottom diameter. At the lowermost end, the inner arch cylinder with the smallest bottom port diameter is placed at the top end, and the upper port diameter of the lower section is equal to the lower port diameter of the upper section. The multi-joint Jnt thus formed is tower-shaped. For details, refer to FIG. The formation process of one of the single-joints is shown, and the other forming processes are the same, and therefore, the U-shaped inner tube 24 is inserted in the node.

The inner arched joint device provided by the invention has the anti-slip effect, and overcomes the defect of single product structure on the market, and the processing method of the kind of the knotter can be realized only by the convex mold, and the concave mold is not needed, which greatly reduces The friction of the material during the forming process is no longer caused by product cracking, wrinkles, scratches, etc., and the produced blank (semi-finished product) has no deformation, high stability, and argon arc welding is continuously welded into the product. .

The above description is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It should be considered as the scope of protection of the present invention.
