The present invention relates to a method of manufacturing a basket, and more particularly to a method of manufacturing a metal basket which contains steps of welding and bending by way of metal bars.
A conventional basket is configured to accommodate objects and is fixed on a kitchen, a bathroom or a storage room. The conventional basket is a plastic basket or a metal basket, wherein the plastic basket is light-weight and cheap, but it is not strong enough to hold the objects securely. However, the metal basket is rigid enough to hold the objects firmly and has outstanding appearance.
As illustrated in
After welding the holder 20 and the body 10 together, two movable connectors 30 are welded on the holder 20 so that the metal basket is pulled outwardly and is retracted inwardly along a drawer by using the two movable connectors 30 and two slide rails of the drawer.
Nevertheless, the multiple first metal bars 101 and the multiple second metal bars 102 are stacked crisscross and are welded together so as to form the body 10, and the holder 20 is bent from the metal rod and is fitted with the opening of the body 10, and wherein the multiple first metal bars 101 and the multiple metal bars 102 of the body 10 are welded together, thus producing the metal basket complicatedly and having high production cost.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide a method of manufacturing a metal basket which contains multiple first metal bars and multiple second metal bars stacked crisscross and welded together so as to form a body, and as bending the body, and the at least two peripheral bars are bent and welded so as to form a holder, thus simplifying manufacturing process and reducing production cost.
A method of manufacturing a metal basket provided by the present invention contains steps of: preparing materials, initial welding, bending, and re-welding.
In a step of preparing materials, multiple first metal bars, multiple second metal bars, and at least two peripheral bars are provided.
In a step of initial welding, the multiple first metal bars and the multiple second metal bars are stacked crisscross and are welded together so as to produce a grid frame which has a base and multiple surrounding sheets connecting with a rim of the base, and when the multiple first metal bars and the multiple second metal bars are stacked crisscross and are welded together, the at least two peripheral bars are welded with the multiple surrounding sheets respectively, wherein each of the at least two peripheral bars has two bending extensions extending from two ends of said each peripheral bar and over two ends of each of the multiple surrounding sheets respectively.
In a step of bending, the grid frame and the multiple surrounding sheets are bent, such that the multiple surrounding sheets of the grid frame are bent upwardly and are perpendicular to the base so as to form a body with an opening facing upwardly, and the two bending extensions of said each peripheral bar and the body are bent and are connected together so as to produce a holder having gaps.
In a step of re-welding, two bending extensions of said each peripheral bar of the holder are welded together.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Referring to
In a step of preparing materials, multiple first metal bars 11, multiple second metal bars 12, at least two peripheral bars 21, and two movable connectors 3 are provided, wherein a length of each of the multiple first metal bars 11 is not equal to that of each of the multiple second metal bars 12.
In a step of initial welding, the multiple first metal bars 11 and the multiple second metal bars 12 are stacked crisscross and are welded together by way of an electric welding machine so as to produce a grid frame 1A which has a base 13 and multiple surrounding sheets 14 connecting with a rim of the base 13. In this embodiment, the multiple surrounding sheets 14 are two opposite first parts 14A and two opposite second parts 14B. When the multiple first metal bars 11 and the multiple second metal bars 12 are stacked crisscross and are welded together, two peripheral bars 21 are welded with the two opposite first parts 14A respectively and are away from the rim of the base 13, wherein each of the two peripheral bars 21 has two bending extensions 211 extending from two ends of said each peripheral bar 21 and over two ends of each of the two opposite first parts 14A respectively. Furthermore, at least one of the multiple surrounding sheets 14 of a body 1 has a recess 141 away from the rim of the base 13, and one of the two peripheral bars 21 is bent so as to form the recess 141 on one of the two opposite first parts 14A.
In a step of bending, the grid frame 1A and the two peripheral bars 21 are bent by using a stamping machine, such that the two opposite first parts 14A and the two opposite second parts 14B of the grid frame 1A are bent upwardly and are perpendicular to the base 13 so as to form the body 1 with an opening facing upwardly. In addition, the two bending extensions 211 of said each peripheral bar 21 and the body 1 are bent and are connected together so as to produce a holder 2 having gaps.
In a step of re-welding, two bending extensions 211 of one of the two peripheral bars 21 of the holder 2 are welded with two bending extensions 211 of the other of the two peripheral bars 21 of the holder 2, and the two movable connectors 3 are welded on the two bending extensions 211 of said each peripheral bar 21 of the holder 2 so as to fix the two movable connectors 3 on two opposite sides of the holder 2, thus manufacturing the metal basket.
In use, the metal basket is pulled outwardly and is retracted inwardly along a drawer by using the two movable connectors 3 and two slide rails of the drawer.

As shown in
Accordingly, the method of manufacturing the metal basket of the present invention has advantages as follows:
the multiple first metal bars 11 and the multiple second metal bars 12 are stacked crisscross and are welded together so as to form the body 1, and the at least two peripheral bars 21 are welded on the multiple surrounding sheets 14 of the body 1 away from the rim of the base 13. When the multiple surrounding sheets 14 of the body 1 are bent upwardly from the base 13, the at least two peripheral bars 21 are bent and connected so as to form the holder 2, thus simplifying manufacturing process, reducing production cost, and enhancing market competitiveness.
While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
