Description
Technical Field
The invention relates to the field of pipe fitting butt joint fixtures, in particular to a pipe fitting butt joint fixture for a laser welding pipe machine.
Background
Laser welding machines, also commonly called laser welding machines and laser welding machines, are machines for processing laser materials, and are divided into laser die welding machines, automatic laser welding machines, laser spot welding machines and optical fiber transmission laser welding machines according to working modes.
Laser deep melting welding generally adopts continuous laser beams to complete material connection, the metallurgical physical process of the laser deep melting welding is very similar to electron beam welding, and an energy conversion mechanism is completed through a 'keyhole' structure. Under the irradiation of laser with high enough power density, the material is evaporated and forms pores. The vapor filled aperture acts like a black body absorbing almost all of the incident beam energy, the equilibrium temperature in the cavity is about 25000C, and heat is transferred from the outer wall of the high temperature cavity to melt the metal surrounding the cavity. The pores are filled with high-temperature steam generated by continuous evaporation of the wall material under the irradiation of the light beam, the walls of the pores surround the molten metal, and the periphery of the liquid metal surrounds the solid material (in most conventional welding processes and laser conduction welding, energy is firstly deposited on the surface of a workpiece and then is conveyed into the interior by transmission). The liquid flow outside the pore wall and the surface tension of the wall layer are in accordance with the steam pressure continuously generated in the pore cavity and keep dynamic balance. The light beam continuously enters the small hole, the material outside the small hole continuously flows, and the small hole is always in a flowing stable state along with the movement of the light beam. That is, the keyhole and the molten metal surrounding the keyhole wall move forward with the forward velocity of the pilot beam, the molten metal fills the void left by the removal of the keyhole and condenses with it, and a weld is formed. All of the above processes occur so fast that the welding speed can easily reach meters per minute. Therefore, uniform welding seams are an easy process, and the butt joint process of a laser pipe welding machine is a difficult process; the workpiece needs to be relatively fixed by a clamp, and high mechanical precision is needed.
In the present stage, the butt joint clamp for the welded pipe fittings is relatively traditional, and the butt joint effect is poor.
