Description

Metal angle tube and application and manufacturing method thereof

The present invention relates to a metal angle tube for a wire rack; in particular, to an inventor of an innovative structural type and manufacturing method in which a wire bonding region is further provided with a recessed space.

According to the iron wire rack, it is also called iron wire shelf. It belongs to a combination detachable rack product type. Because its bearing surface structure is mainly formed by iron wire welding, it has good rigidity and strong force, and has a combination. The flexible and convenient structure of the dismantled structure currently has a considerable market share in the modular furniture market.

The wire mesh layer of the wire rack (usually referred to as the iron wire net in the industry) will be welded first, and then welded with the metal angle tubes. The parts of the iron wire mesh layer to be assembled with the angle tube will be set in advance. a first-direction iron wire welding end and a second-direction iron wire welding end which are mutually staggered at an angular interval, and a space formed between the two-way wire welding ends allows the metal angle tube to be placed therein for carrying out Subsequent welding assembly process.

In order to achieve the best precision and quality of the finished wire rack, in order to prevent the skew of the wire mesh layer and the vertical frame in the future, the angle tube must be placed at the preset point on the processing equipment. On the outer circumference of the column fixture, the wire mesh layer will also be placed on another fixture on the processing equipment that has been set up at the same position; that is, regardless of the metal angle tube or the iron mesh layer, The position on the jig of the processing equipment is not allowed to change again. Therefore, there is often a problem in the manufacturing process, that is, the first direction of each part of the wire mesh layer to be assembled with the metal angle pipe The wire end of the wire and the second wire wire welding end, in the process of the trimming and the welding forming process, the convex elongation of the end of the corresponding angle tube is inevitably caused by an excessively long or too short error, and the positive and negative tolerances thereof The value is only about 2mm. However, if the convex elongation is too long, the metal angle tube will be stuck and cannot be placed due to its rigid structure. In this case, it must be modified by manual grinding. To size The state can be continued, the application is quite time-consuming and inconvenient, and the manufacturing efficiency is often greatly affected; on the contrary, if the convex elongation is too short, the problem is more serious, because the gap is small, although it can be transmitted through the bulky solder. Convergence, but when the gap is large, the entire wire frame body may be seriously damaged and costly due to the inability to weld, and if the gap is too large, the industry will still force the extension through the solder stack. When the filling is completed, the welded portion tends to exhibit a tapered shape and a rather unattractive pattern, thereby seriously affecting the product quality of the wire rack.

Therefore, in view of the problems existing in the above-mentioned conventional wire-line rack assembly technology, how to develop an innovative structure and manufacturing method that can be more ideal and practical, and the relevant industry should further consider the goal and direction of breakthrough. .
