Abstract

The invention provides a magnetic beam powder type powder feeding device for laser additional material manufacturing. The magnetic beam powder type powder feeding device comprises a frame body, a powder charged device, powder pipe position adjustment devices, magnetic beam powder devices and a laser emission unit. The powder charged device comprises a charging unit and a powder feeding unit, wherein the charging unit is used for charging powder, the powder feeding unit is used for conveying the charged powder, the charging unit is arranged at an upstream powder inlet of a powder pipe, and a powder pipe downstream powder outlet of the powder feeding unit is arranged on the lower portion of the frame body through the powder pipe position adjustment devices. The powder pipe position adjustment devices are arranged on the lower portion of the frame body in the circumferential direction. The magnetic beam powder devices are assembled to the powder pipe downstream powder outlet and are provided with magnetic fields enabling the charged powder to be deviated. A laser head of the laser emission unit is arranged on the frame body, and a light outlet of the laser head is aligned with the convergence focus point of the charged powder sent out by the powder pipe. The magnetic beam powder type powder feeding device has the beneficial effects that the convergence of a powder flow is greatlyimproved, and the magnetic beam powder type powder feeding device is greatly helpful to improvement of the forming quality of a powder feeding type laser additional material manufacturing technology;and an original laser can be improved, and thus the cost is lowered.

Description

technical field

[0001] The invention relates to a magnetic beam powder feeding device for laser additive manufacturing. Background technique

[0002] Since the concept of laser additive manufacturing was put forward, laser additive manufacturing technology has been continuously developed. Due to its advantages of being able to form complex parts with excellent organizational properties, a variety of processing materials, and a high degree of flexibility, laser additive manufacturing technology can be widely used in the direct manufacturing of complex parts. However, the laser additive manufacturing process is accompanied by complex interactions between the laser beam, powder, and molten pool morphology, which makes the control of the additive manufacturing process more complicated. At present, there are two typical methods for laser additive manufacturing of high-performance metal parts, one is laser cladding deposition technology based on synchronous powder feeding, and th...
