Abstract
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
The present invention relates to a kind of welding method, the welding method of particularly a kind of " H " shape metal material belt.
Background technology
Present frame clsss sheet metal goods adopt following several preparation methods usually:
1. monoblock sheet material or whole piece band material carry out whole drawing, stock utilization is low like this, fixing as the aperture mask plate with in the FRAME COMPONENTS manufacturing, carry out whole drawing with whole piece band material, its stock utilization only is about 45%, waste of raw materials is serious, and tighter to the width of steel band requirement, the production cost height.
2. with the drawing after welding of L moulding mixture sheet, the stock utilization height, but width of steel band requires size bigger, and steel band purchase cost height does not match as steel band sub-cut width, and steel band sub-cut waste is big, and manufacturing cost is also higher.
Summary of the invention
The welding method that the purpose of this invention is to provide a kind of " H " shape metal material belt, by two parallel ribbon sheet metals, with a vertical with it horizontal flitch, carrying out " H " shape by one group of pinpoint anchor clamps accurately locatees, one group of parallel plate-like weldering wheel carries out equidirectional parallel welding of while to its two weld seams simultaneously, finish the shaping of " H " shape metal material belt, use for follow-up tablet stamping procedure.
For reaching above purpose, the present invention takes following technical scheme to be achieved:
The welding method of a kind of " H " shape metal material belt comprises the steps:
A. at two outsides of two ribbon sheet metal arranged outside location-plate; The inboard is provided with two inboard location-plates, makes two ribbon metallic plates be parallel sending to mutually; Width between two ribbon sheet metal inboards is the inner width size of shaping tablet;
B. send a side of inboard location-plate at strip metal sheet material, be provided with two parallel to each other and perpendicular to the locating piece of interior outside location-plate; A horizontal flitch is clipped between two locating pieces, makes the inboard lap-joint of horizontal flitch two ends and strip metal sheet material form two weld seams,
C. adopt one group side by side, parallel plate-like weldering wheel carries out equidirectional parallel welding to two weld seams simultaneously;
D. after welding is finished, dismantle in two locating pieces away from that locating piece of inboard location-plate, continue to make two ribbon metallic plates to be parallel sending to mutually, the horizontal flitch of another same size is clipped between two locating pieces, form two weld seams at horizontal flitch two ends and the inboard lap-joint of strip metal sheet material, repeating step c, the distance between this horizontal flitch and the previous horizontal flitch that has welded is the length dimension of shaping tablet;
E. repeating step d makes parallel banded sheet metal all send welding sequence, and forms the H shape band material of disjunctor, prepares the shaping tablet for the back operation.
In the said method, with sending constantly into of banded sheet metal, for guaranteeing the depth of parallelism, the length of described outside location-plate should be long as much as possible, should be the length of 1.5 times shaping tablet at least.The length of described inboard location-plate should be the interior long size of shaping tablet at least.The width of described horizontal flitch should be a bit larger tham 2 times for shaping tablet minor face width.
The advantage of welding method of the present invention is:
1. can improve the utilization rate of product material greatly, the utilization rate of material can be brought up to more than 80%, effectively reduces production costs.
2. the steel band Purchasing specification is required to relax greatly: existing is example with the fixing width with sub-cut steel band required in the FRAME COMPONENTS manufacturing of 37cm aperture mask plate: as adopting monoblock sheet material or whole piece band material to carry out whole drawing and adopting the width of the required sub-cut steel band of L moulding mixture sheet drawing after welding to be: whole punching press 330mm, L moulding mixture sheet drawing 350mm after welding; As adopt the width of sub-cut steel band required for the present invention to be: 51mm improves the utilization rate of the material of steel band sub-cut greatly.
3. the relatively production of tablets such as " L ", " four spot welding ", production technology of the present invention is simple, and is die needed, equipment is few, easily is automated production.

The specific embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the welding method of a kind of " H " shape metal material belt comprises the steps:
A. at two outsides of two steel bands, 1,2 arranged outside location-plate 3; The inboard is provided with two inboard location-plates 4, makes two steel bands be parallel sending to mutually; Article two, the width between the steel band inboard is the be shaped inner width size of tablet of Fig. 3; With sending constantly into of two steel bands, for guaranteeing the depth of parallelism, the length of outside location-plate 3 should be long as much as possible, should be the length of 1.5 times shaping tablet at least, and is constant in welding process to guarantee the distance between two steel bands; The length of inboard location-plate 4 should be the interior long size of shaping tablet at least.
B. send a side of inboard location-plate 4 at two steel bands, be provided with two parallel to each other and perpendicular to the locating piece 5,7 of interior outside location-plate; A horizontal flitch 6 is clipped between two locating pieces, makes horizontal flitch two ends and two weld seams 10 of two the inboard formation of steel band, the width of horizontal flitch should be a bit larger tham 2 times for shaping tablet minor face width.Locating piece 5,7 can guarantee at X, Y both direction displacement can not be arranged in horizontal flitch 6 welding processes.
C. adopt one group side by side, parallel plate-like weldering wheel carries out equidirectional parallel welding to two weld seams 10 simultaneously.
