Abstract
The invention relates to a method for welding a thin-wall variable-frequency motor shell by laser, in particular to a method for welding a thin-wall variable-frequency motor shell by laser, which is suitable for manufacturing various thin-wall small-diameter variable-frequency motor shells. The method for welding the thin-wall variable-frequency motor shell by laser is characterized in that after being circularly rolled, a 304 stainless steel material with a wall thickness of 0.3mm, a length of 185mm and a width of 58mm is formed into a pipe shape with butted welded junctions; the pipe-shaped stainless steel material is put in a welding tool and is sealed by an automatic three-dimensional welder. The method has high welding strength, smooth welding joint, no burr, no workpiece deformation and high size precision and can be used for automation mass production. Plasma arc welding adopted by a conventional process is easy to cause welding deformation, weld through a local part and form a welding beading on the inner wall, is not easy to control diameter size and causes a motor shell to be processed needs subsequently. The conventional process does not obtain breaking progresses after multiple times of improvement, and afterwards, a method for drawing seamless pipes is used, but due to low yield and steep cost which influences the economic benefit, the method also cannot be popularized.
Description
Technical field
The present invention relates to the application of laser welding technology, be specifically related to a kind of method for laser welding of thin-wall variable-frequency motor shell, be applicable to and make all kinds of thin-walled minor diameter variable-frequency motor shells.
Background technology
Thin-wall variable-frequency motor shell is the external packing of micromachine, and thin-walled tubular structure, its wall thickness are .3mm, and material is 304 stainless steels.The internal diameter size precision prescribed high (± 0.05mm), the commissure does not allow the overlap salient point, with the installation of stator be interference fits, the tensile strength that needs weld seam is 5000N/34mm, and the appearance requirement weld seam is attractive in appearance, and is smooth.Traditional handicraft adopts PLASMA ARC WELDING, causes welding deformation easily, the bad control of diameter dimension; Local burn-through easily, inwall forms overlap, needs following process; Through repeatedly improving all achieving no breakthrough property progress, after take the method for drawing seamless pipe again, but because lumber recovery is low; Cost is excessive, influences economic benefit, also can't promote.
Summary of the invention
The method for laser welding that provides a kind of thin-wall variable-frequency motor shell of the present invention, its weld strength is high, smooth welding joint, no burr, workpiece does not have distortion, and dimensional accuracy is high, can automatic batch production.
The method for laser welding of thin-wall variable-frequency motor shell of the present invention is characterized in that with a kind of wall thickness be 0.3mm, and length is 185mm, and width is 304 stainless steel materials of 58mm.Round as a ball back forms the tubulose of weld bond butt joint, is placed in the welding tooling, uses the automatized three-dimensional bonding machine it is sealed.
The method of described a kind of welding thin-wall variable-frequency motor shell by laser, its welding procedure is:
A, round as a ball motor housing is fixed on the frock of three-dimensional working platform of laser-beam welding machine, makes weld seam concentric and parallel with the workbench that moves.
The slit that B, adjustment workbench make welding and microscopical horizontal line and make argon shield gas nozzle aligning commissure on the same line.
C, according to the specification adjusting process parameter of motor housing, operating voltage is 220V, simple venation energy 1-5J; Pulse duration 6-8ms, the depth of weld is less than 0.5mm, laser welding frequency 8-10Hz; The stroke of control process velocity and weld length in automatic control console is set the parameter of pressing straight line processing: first point, straight line: X coordinate; The Y coordinate, Z coordinate, 1010 (advancing the rifle shooting); Second point, straight line: X coordinate, Y coordinate, Z coordinate, 0101 (close rifle and move back rifle).And adjustment cold water flow: 60L/ minute.The protective gas argon pressure is 0.3MPa.
D, start spot welding, to weld ejection protective gas argon gas, movable workbench is accomplished the welding in slit automatically simultaneously.
The equipment that uses is the accurate automatic laser welding machine of ADT-TP3340 type, and its technical parameter is working-laser material: the Nd:YAG crystal; Single pulse energy: 0-30J; Pulse duration :≤20ms; The depth of weld≤3mm; Laser welding frequency≤15Hz; The light beam and the angle of divergence: 10mrad; Repeatable accuracy: 0.02mm; Speed＜2mm/s; Cooling water flow: 60 liters/minute.The protective gas that uses is argon gas, and pressure is 0.3MPa.
Because Laser Welding is a kind of new type of welding method, not needing filler and solder flux, laser welding during weldering is to the metal surface with high-intensity bombardment with laser beams; Through the interaction of laser and metal, in the extremely short time, metal absorb laser be converted into heat energy make metal molten after crystallisation by cooling form welding. smooth welded seam, firmly; Intensity is high; Be out of shape for a short time, pollute fewly, efficient is high.Suitable fully requirement of making thin-wall variable-frequency motor shell.Do protective gas with argon gas in addition, burr can not occur after the welding.The thin-wall variable-frequency motor shell that adopts this method to make need not postorder processing.
Embodiment
Existing is example to weld a kind of specification thin-wall variable-frequency motor shell, and the application in making thin-wall variable-frequency motor shell further specifies to laser welding.Its requirement is shell wall thickness 0.3mm, and diameter is 60mm, and length is 58mm.At first, round as a ball then by carrying material under the requirement of diameter and length.Selecting working-laser material for use is the Nd:YAG crystal; Single pulse energy is that the accurate automatic laser welding machine of the ADT-TP3340 type of 0-30J seals, and its welding procedure is:
A, the motor housing material after round as a ball is fixed on the frock of three-dimensional working platform of laser-beam welding machine, makes weld seam concentric and parallel with the workbench that moves.
Slit and microscopical horizontal line that B, adjustment workbench make welding and make protective gas argon gas nozzle alignment weld seam on the same line.
C, according to the specification adjusting process parameter of motor housing, operating voltage is 220V, simple venation energy 3J, pulse duration 7ms, depth of weld 0.3ms, laser welding frequency 9Hz, and 30 liters/minute of adjustment cold water flows; Protective gas is an argon gas, and pressure is 0.4MPa.Control process velocity 1mm/s in automatic control console; Weld length is 58mm; Set the parameter of pressing straight line processing: first point, straight line: X coordinate, Y coordinate, Z coordinate, 1010 (advancing the rifle shooting); Second point, straight line: X coordinate, Y coordinate, Z coordinate, 0101 (close rifle and move back rifle).
