Blade cladding equipment for tracking blade cladding track by using sensor
Technical Field
The invention relates to a knife-shear manufacturing device, in particular to a knife-edge cladding device for tracking a knife-edge cladding track by using a sensor.
Background
Laser cladding can be roughly divided into two main categories, namely preset laser cladding and synchronous laser cladding, according to the supply mode of cladding materials. The preset laser cladding is to place cladding materials on the cladding part of the surface of a base material in advance, then adopt laser beam irradiation scanning to melt, the cladding materials are added in the form of powder, wire and plate, wherein the powder form is the most commonly used. The synchronous laser cladding is to directly feed cladding material into a laser beam so as to complete feeding and cladding simultaneously. The cladding material is mainly fed in the form of powder, and some materials are synchronously fed by adopting wires or plates. The blade cladding of the knife shear adopts a synchronous laser cladding mode to clad the blade. The strength of the cutting edge of the knife shear is improved by a cladding technology.
At present, the automation equipment for knife and shear cladding is still blank in the market, generally adopts the semi-automatic production mode of manual feeding and laser cladding equipment, and the cutter is pushed to enter the laser cladding equipment through the manual work to clad, and the cladding mode has low efficiency and high labor cost, has certain requirements on the proficiency of operators, and is not beneficial to batch production.
