Description
Technical Field
The invention relates to a cladding nozzle and a laser cladding device, and belongs to the field of laser processing.
Background
The laser cladding refers to a process method that selected coating materials are placed on the surface of a cladding substrate in different material adding modes, and are melted together with a thin layer on the surface of the substrate through laser irradiation, and the surface coating which is extremely low in dilution degree and is metallurgically bonded with the substrate is formed after rapid solidification, so that the wear resistance, corrosion resistance, heat resistance, oxidation resistance, electrical characteristics and the like of the surface of a base layer are obviously improved, and the purpose of surface modification or repair is achieved. The laser cladding can be roughly divided into two main types, namely preset laser cladding and synchronous laser cladding, according to the feeding mode of cladding materials.
1) The preset laser cladding is to place cladding material on the cladding part of the surface of the base material in advance, then adopt laser beam irradiation scanning to melt, the cladding material is added in the form of powder, silk and plate, wherein the cladding material is most commonly used in the form of powder;
2) Synchronous laser cladding is to directly send cladding material into laser beam to complete feeding and cladding simultaneously. Cladding materials are mainly fed in powder form, and sometimes wire rods or plates are used for synchronous feeding.
The synchronous feeding method is the most advanced laser cladding technology at present, can greatly improve cladding quality, reduce dilution rate of cladding layers and heat influence of base materials, can reduce the required cladding energy by more than one time compared with a preset cladding method, and is easy to realize automatic control. The lateral feeding is good in controllability of the melted material and the light because the distance between the melted material outlet and the light outlet is long, and the phenomenon that the melted material is melted prematurely to block the light outlet can be avoided. The limitation of the single-side feeding mode is that the feeding is only one direction, so that when the processing surface is a plane, the processing track can only be a straight line, and curves such as circles, squares and the like cannot be taken, and the convenience and the flexibility of the feeder in processing are limited. The coaxial feeding overcomes the defect of single-side feeding, and can uniformly disperse the melted material into a ring shape, then, the ring shape is converged and then, the ring shape is sent into a focused laser beam.
Chinese patent CN201823642U discloses a laser cladding coaxial powder feeding nozzle comprising a pilot protection gas flow, which is sleeved outside the powder sleeve and is screwed with the powder sleeve. An open guide protection gas channel is formed between the inner conical surface of the guide protection gas sleeve and the outer conical surface of the powder sleeve, and a plurality of air inlets are uniformly arranged on the guide protection gas sleeve and are the same as the upper part of the guide protection gas channel.
The laser cladding coaxial powder feeding nozzle with the guiding airflow has the following advantages:
the external guiding protection air flow is added, so that the powder flow can be guided, the convergence degree of the powder flow is improved, the laser melting pool can be well protected, the nozzle can work more stably, and the service life of the nozzle is prolonged.
However, the following disadvantages still exist:
the gas channel is composed of a plurality of gas inlets, and the existence of manufacturing errors and assembly errors of parts cannot ensure that the gas pressure and the flow rate of each gas inlet are the same, and finally the uniformity of gas sprayed into the cladding area cannot be ensured, so that the cladding layer cannot be oxidized at all.
