Problems solved by technology
However, in actual work, various pipelines such as powder, gas, and water are often distributed on the coaxial powder feeding head, and each pipeline needs to be dismantled when rotating; after the adjustment is completed, it is very inconvenient to reinstall
Secondly, due to the fixed powder feeding channel of the traditional coaxial powder feeding head, when the powder-carrying airflow and powder feeding volume are constant, the concentration distribution of the powder is determined and cannot be adjusted, which limits its industrial application

The invention provides a powder feeding head for laser coaxial cladding, which includes an outer cylinder wall, an inner cylinder wall, a cooling water chamber, an outer ring of a powder feeding nozzle, an inner ring of a powder feeding nozzle, and an outer ring of a powder feeding nozzle. The ring and the inner ring are respectively composed of a number of symmetrically distributed circumferentially and overlapping outer movable support plates and inner movable support plates. The inner ring and outer ring of the powder feeding nozzle form a circumferentially closed tapered powder feeding nozzle; the outer movable The support plate and the inner movable support plate are respectively connected with the outer cylinder wall and the inner cylinder wall through hinges; there is a linkage mechanism between the outer movable support plate and the inner movable support plate, so that the outer movable support plate can drive the inner movable support plate around the hinge Do corresponding rotation; the powder feeding head is also equipped with a support plate adjustment device that can adjust the angle between the outer movable support plate and the axis of the outer cylinder wall. The invention can achieve the purpose of changing the converging point of the powder flow and the powder concentration distribution without dismantling various pipelines.
Description
technical field [0001] The invention relates to a laser coaxial cladding powder feeding head which can change the powder converging point and concentration distribution, belongs to a supporting device for laser processing, and is suitable for laser cladding, forming and material surface alloying. Background technique [0002] Synchronous laser cladding is to use the powder feeding system to send the alloy material powder directly into the laser action area through the powder-carrying airflow during the laser cladding process, so that it can be melted with the base material at the same time, and then cooled to form a metallurgical bond. The simultaneous powder feeding cladding method is beneficial to reduce the dilution rate of the cladding layer and realize the control flexibility of materials, structures and parts shapes. It is currently the most widely used laser additive manufacturing technology. [0003] Synchronous laser cladding can be divided into lateral powder feedi...
