Abstract
The invention relates to scalpel welding devices and welding processes, in particular to a multilayer scalpel stitch welding device and a welding process. The multilayer scalpel stitch welding device and the welding process aims at solving the problems of blade shattering proneness and high defective rates in the field of scalpel stitch welding of the existing stitch welding technology. The stitch welding device comprises two correspondingly-arranged electrode bars, an electrode control device for controlling the feeding of the electrode bars, a welding table and a blade fixing unit fixed on the table; the front ends of the electrode bars are wide strip chromium zirconium copper electrode tips of 1.2 mm. The multilayer scalpel stitch welding device and the welding process thereof ensure the stability of the fixing of three layers of blades as well as no cracking of the blades.
Description
Technical field
The present invention relates to a kind of welder and welding procedure of scalpel, relate to specifically a kind of stitch welding device and stitch welding technique of multilayer scalpel.
Background technology
Resistance welder (resistance welding machine) is pressed in welded piece between two electrodes, and impose electric current, resistance heat effect that workpiece contact-making surface and adjacent domain produce is heated fusing or mecystasis to utilize electric current to flow through, and makes it to form a kind of method of metal combination.Resistance welder welding method mainly contains spot welding, seam weldering, projection welding, pressure welding.
Conventionally pressure welding is the welding between two-layer workpiece, for the welding between multilayer workpiece, conventionally adopts and on a plate, opens several holes therein, carries out the method for plug welding, two plates are connected, then four seams that are used in two plate junctions all burn-ons, and makes it sealing.
Along with the development of embedded-type electric scalpel, at present need to be by welding after three layers of blade stack, not only technique is loaded down with trivial details to adopt general stitch welding device and stitch welding, and defect rate is high, electric current is excessive easily shatter by blade, and electric current is too small cannot be fixed multi-layer cutter blade, affects yield rate.
Summary of the invention
The present invention is directed to easy the to be shatter blade that current stitch welding technology exists in scalpel stitch welding field, the problem that defect rate is high, a kind of welder for scalpel stitch welding is provided, described stitch welding device comprises two corresponding electrode bars that arrange, electrode control device for electrode bar feeding control, welding bench and be fixed on the blade fixing device of workbench, the front end of described electrode bar is wide the chromium zirconium copper electrode end of 1.2 millimeters.
Simultaneously, for this equipment, supporting a kind of stitch welding for scalpel stitch welding, the described stitch welding employing pressure welding mode of providing, described pressure welding mode is to 30A ~ 50A DC current in 2s, top electrode rod distance blade 0 ~ 3mm to be welded, controls DC current, makes it be divided into two parts, a part is penetrating current, another part is outer circular current, 3/4 left and right that described penetrating current is DC current, and described outer circular current is DC current below 1/4.
By to supplying with the control of electric current, and distance between top electrode rod and blade, its penetrating current can be fixed multilayer scalpel, outer circular current has ensured that its current strength is unlikely to make blade cracked, has ensured the complete of bag cutter shell.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Wherein 1-top electrode rod, 2-bottom electrode rod, 3-electrode control device, 4-welding bench, 5-blade fixing device, 6-electrode tip, 7-blade to be processed.
Detailed description of the invention
Embodiment 1
As shown in Figure 1, a kind of welder for scalpel stitch welding, described stitch welding device comprises two corresponding electrode bars that arrange, be top electrode rod 1 and bottom electrode rod 2, electrode control device 3 for electrode bar feeding control, welding bench 4 and be fixed on the blade fixing device 5 of workbench, the front end of described electrode bar is wide the chromium zirconium copper electrode end 6 of 1.2 millimeters.
First just blade to be welded is fixed on welding bench 4 by blade fixing device 5, then by electrode control device 3, control top electrode rod 1 and bottom electrode rod 2 mutually close, in the time that the distance of top electrode rod 1 distance blade 7 to be processed is 0 ~ 3mm, stop compressing into, and starting current simultaneously, in 2s, supply with the DC current of 30A ~ 50A.Now, approximately the electric current of 30A, as penetrating current, accounts for 3/4 of total current, and approximately the electric current of 10A, as outer circular current, accounts for 1/4 of total current.Thereby in ensureing that blade is not cracked, three layers of stability that blade is fixing are ensured.
