Follow-up powder-receiving tray of laser cladding device

Abstract

The invention relates to a follow-up powder-receiving tray of a laser cladding device. The tray is positioned on a mobile flat guide rail and a triangular guide rail of a tail table of the cladding device by virtue of a rolling and rubbing supporting body so as to achieve a positioning function that the tray moves linearly along the axial direction of a to-be-processed workpiece. An electromagnet (permanent magnet) is installed on a column where the cladding device drives a laser head to move along the axis direction of the workpiece, and the electromagnet attracts an attraction body on the powder-receiving tray to provide power to the movement of the tray, so that the powder-receiving tray moves synchronously with the laser head along the axis direction of the workpiece. A magnet installation device is provided with an elastic floating device to ensure that the magnet and an attraction face are effectively attracted under a small gap condition, so that the device is safe and reliable to operate. When the column moves to a position beyond the tail table, the powder-receiving tray is automatically separated from the magnet on the column under the effect of a resisting force of the tail table. When the column moves to the middle position between the tail table of the cladding device and a main shaft box, the column and the tray are automatically attracted and move synchronously.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a laser cladding device follow-up powder receiving tray structure and an application method thereof. Background technique [0002] Metal materials use laser to modify the surface of materials, which is recognized by more and more fields and manufacturers. At present, this processing method and equipment have begun to be used in batch product processing. At present, the most common shapes of workpieces manufactured by laser cladding are cylindrical surfaces and Plane, the follow-up powder tray we designed is mainly used in laser cladding processing equipment for cylindrical outer surfaces. The laser cladding process is to send the metal powder material to be covered on the surface of the cylindrical workpiece into the laser processing molten pool by pneumatic powder feeding or gravity powder feeding.

Problems solved by technology

The laser cladding process is to send the metal powder material to be covered on the surface of the cylindrical workpiece into the laser processing molten pool by pneumatic powder feeding or gravity powder feeding. Due to the difference in matching between the powder beam flow and the molten pool size, the cladding process varies with the The maturity is different, and the powder utilization rate varies from 20% to 90%. In this way, the excess powder and scale will fall along the sides of the workpiece during the cladding process. If there is no powder tray, the powder will fall directly on the guide rail. , sandwiched between the mating surface of the tail table and the guide rail of the bed, resulting in the loss of matching accuracy, reducing the life of the cladding device until the basic processing function is lost

At the same time, the heavy metal content in various alloys used in laser cladding is high, and if they are not recycled and reused in time, they will easily cause environmental pollution and damage the reputation of green processing. Therefore, the powder receiving tray is indispensable in the laser processing process.
