Problems solved by technology
[0003] 1. The entire sheet or strip is stamped and formed as a whole, so that the material utilization rate is low. For example, in the manufacture of frame parts for fixing the shadow mask plate of a color picture tube, the entire strip is used for integral stamping and forming, and the material utilization rate is only About 45%, the waste of raw materials is serious, and the requirements for the width of the steel strip are strict, and the production cost is high
[0004] 2. Use L-shaped blanks to be welded and stamped to form, and the material utilization rate is high, but the steel strip width requires a large size, and the steel strip purchase cost is high. If the steel strip cutting width does not match, the steel strip cutting is wasteful, and the manufacturing The cost is also higher

Embodiment Construction
[0024] a. Set two outer positioning plates 3 on the outer sides of the two steel strips 1 and 2; two inner positioning plates 4 are arranged on the inner side, so that the two steel strips are sent in parallel to each other; the width between the two steel strips is image 3 The inner width of the forming material; with the continuous feeding of the two steel strips, in order to ensure parallelism, the length of the outer positioning plate 3 should be as long as possible, at least 1.5 times the length of the forming material, to ensure that the two The distance between the steel strips is constant during the welding process; the length of the inner positioning plate 4 should be at least the inner length of the formed blank.
[0025] b. On the side where the two steel strips are sent out of the inner positioning plate 4, set two positioning blocks 5 and 7 that are parallel to each other and perpendicular to the inner and outer positioning plates; sandwich a cross-strip 6 between...

The invention discloses a welding method for an 'H'-shaped metal strip, which is characterized in that relative positions of two parallel strip metal plates and a transverse plate which is perpendicular to the two parallel strip metal plates is subjected to 'H'-shaped precise positioning; two welded seams on lapped positions of two edges of the 'H'-shaped transverse plate and the two parallel strip metal plates are simultaneously welded by a group of parallel discal welding wheels; and after feeding is performed by a feeder according to the length of a formed plate, the next transverse plate is welded until the integral H-shaped strip is formed. The welding method can greatly save raw materials of metal plate frame products, reduce energy consumption and repetitive operation, widen the purchasing specification range of steel strips, and greatly reduce the production cost of the metal plate frame products.
Description
technical field [0001] The invention relates to a welding method, in particular to a welding method of an "H" shaped metal strip. Background technique [0002] The current frame metal sheet products usually adopt the following preparation methods: [0003] 1. The entire sheet or strip is stamped and formed as a whole, so that the material utilization rate is low. For example, in the manufacture of frame parts for fixing the shadow mask plate of a color picture tube, the entire strip is used for integral stamping and forming, and the material utilization rate is only About 45%, the waste of raw materials is serious, and the requirements for the width of the steel strip are relatively strict, and the production cost is high. [0004] 2. Use L-shaped blanks to be welded and stamped to form, and the material utilization rate is high, but the steel strip width requires a large size, and the steel strip purchase cost is high. If the steel strip cutting width does not match, the s...
