Description

Technical Field

[0001] The utility model relates to the technical field of laser cladding heads, in particular to a laser cladding head with a condensation channel. Background Art

[0002] Laser cladding head is a key component used in laser cladding technology, mainly used to form a coating on the metal surface or repair the metal surface. Laser cladding is a high-temperature processing technology that focuses laser energy on a specific area on the workpiece surface to heat the metal powder or wire to above the melting point, and then forms a layer of metal coating on the surface. Publication No. CN217709675U discloses a laser cladding head. The split cladding head is composed of a material shell, a conveying shell and a material discharge assembly. The existing nozzle has only one powder feed channel, which is not conducive to changing powder or changing different particle sizes during the cladding process. The laser cladding head is designed for powder materials, and a stirring component is used to stir and convey the powder conveyed inside the feeding shell inside the conveying shell to prevent the powder materials from agglomerating and clogging. However, since the laser cladding head is not equipped with a cooling mechanism such as a condensation inner channel, the laser cladding head will be subjected to a considerable heat load during the laser cladding process. If there is a lack of an effective cooling mechanism, the laser head may overheat, resulting in performance degradation, shortened life, and even damage. At the same time, poor cooling effect of the laser head may lead to unstable energy output, which in turn affects the uniformity and quality of the coating. Therefore, it needs to be improved. Utility Model Content

[0005] Preferably, the condensation inner channel and the connecting hose are both arranged in a surrounding manner, and the water inlet pipe and the water outlet pipe are both fixedly connected to the pipe body. Here, the surrounding arrangement allows the condensate to circulate inside the connecting hose, and the condensate can effectively absorb the heat brought by the laser thermal effect and reduce the temperature of the powder spray nozzle end, thereby preventing overheating problems and ensuring a better cooling effect of the laser head.

[0006] Preferably, the storage box is in an arc shape, and the outer surface of the mounting cover is evenly fixed with anti-skid convex strips. Here, the arc storage box is more compatible with the tube body, and the anti-skid convex strips increase the friction between the staff's hand and the contact surface, which helps to twist the mounting cover.

Here, by injecting condensate into the storage box, a small water pump is used to circulate the condensate inside the connecting hose, thereby effectively reducing the heat in the condensate inner channel.

[0008] Preferably, a dust cover is provided at the bottom of the lower tube head, a connecting strip is symmetrically fixedly installed on the surface of the dust cover, a supporting sheet is fixedly installed on the surface of the connecting strip, an upper magnetic sheet is fixedly installed at the bottom of the tube body, and a lower magnetic sheet is fixedly installed on the top of the supporting sheet. Here, the dust cover is used to block the laser channel of the lower tube head to prevent the laser channel from easily absorbing dust when the laser cladding head is not in use, which makes it difficult to maintain and clean.

[0009] Preferably, the connecting strip, the supporting sheet and the dust cover are all made of plastic material. Here, the plastic material is light in weight and prevents the upper magnetic sheet and the lower magnetic sheet from falling off after being attracted and attached to each other.

[0010] Preferably, the upper magnetic sheet and the lower magnetic sheet are fitted together. Here, the upper magnetic sheet and the lower magnetic sheet are attracted and fitted together, so that the support sheet is fixed to the bottom of the tube body.

In the utility model, by providing the dust cover, the connecting strip and the supporting sheet, the upper magnetic sheet and the lower magnetic sheet are attracted and fit together, so that the supporting sheet is fixed to the bottom of the tube body, so that the dust cover blocks the laser channel of the lower tube head, preventing the laser channel from absorbing dust when the laser cladding head is not in use, which makes it difficult to maintain and clean.

[0027] See also Figure 2-5 The inner channel 5 of the condensation and the connecting hose 12 are both arranged in a surrounding manner. The water inlet pipe 6 and the water outlet pipe 7 are both fixedly connected to the pipe body 1. The surrounding arrangement allows the condensate to circulate inside the connecting hose 12.
