[0002] Laser cladding is a new surface modification technology. Laser cladding uses high-energy laser beams to irradiate the metal surface and induce chemical reactions.

By adding cladding materials to the surface of the substrate and using a high-energy-density laser beam to melt it together with a thin layer on the surface of the substrate, a metallurgically bonded additive cladding layer is formed on the surface of the base layer, which has the advantages of strong bonding and reliable performance, and can significantly improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance or electrical properties of the surface of the substrate material, so as to achieve the purpose of surface modification or repair. During the operation of the laser cladding equipment, it is necessary to cooperate with the powder feeding device to continuously add materials into the laser beam to achieve the cladding effect.

[0019] A method for assembling a powder feeding device for laser cladding comprises the following steps:

[0020] Step 1: Pull the baffle to open the feeding port, add the powder into the storage box from the feeding port, turn on the third motor to drive the seventh pulley to rotate, and as the seventh pulley rotates, the first feeding auger shaft is driven to rotate, and as the first feeding auger shaft rotates, the powder in the storage box is transferred from the discharge port to the first powder delivery pipe;

[0021] Step 2: Turn on the first motor to drive the third pulley to rotate. As the third pulley rotates, the second feed auger shaft is driven to rotate. As the second feed auger shaft rotates, the powder transferred to the first powder delivery pipe is transported up along the first powder delivery pipe to the receiving hopper.

[0022] Step three: The powder in the hopper falls into the second powder feeding pipe through the drop pipe. The second motor is turned on to drive the fifth pulley to rotate. The rotation of the fifth pulley drives the third feed auger shaft to rotate. The powder is transported along the second powder feeding pipe as the third feed auger shaft rotates. The transported powder falls from the discharge port into the powder feeding hose, and then is sent from the powder feeding hose into the laser cladding equipment to realize powder feeding.

[0023] The present invention has at least the following beneficial effects:

[0024] 1. Compared with the existing powder feeding device, the powder feeding device and powder feeding method for laser cladding are equipped with a first powder feeding tube receiving hopper, a second powder feeding tube, a drop tube, a discharge outlet powder feeding hose, a first feed auger shaft, a second feed auger shaft and a third feed auger shaft. The third motor drives the seventh pulley to rotate, and the first feed auger shaft is driven to rotate with the rotation of the seventh pulley. With the rotation of the first feed auger shaft, the powder in the storage box is transferred from the discharge outlet to the first powder feeding tube. The first motor drives the third pulley to rotate, and the second feed auger shaft is driven to rotate with the rotation of the third pulley. With the rotation of the second feed auger shaft, the powder in the storage box is transferred from the discharge outlet to the first powder feeding tube. The powder in the first powder feeding pipe rises along the first powder feeding pipe and is transported to the receiving hopper. The powder in the receiving hopper falls into the second powder feeding pipe through the dropping pipe, and the second motor is turned on to drive the fifth pulley to rotate. The rotation of the fifth pulley drives the third feeding auger shaft to rotate. The powder is transported along the second powder feeding pipe as the third feeding auger shaft rotates. The transported powder falls from the discharge port into the powder feeding hose, and is then sent from the powder feeding hose into the laser cladding equipment to realize powder feeding. This solves the problem that the existing powder feeding device has a fixed structure and can only feed powder from a fixed direction, and the powder feeding direction and angle cannot be adjusted, thereby reducing the powder feeding efficiency.

[0025] 2. Compared with the existing powder feeding device, this powder feeding device for laser cladding and its powder feeding method are equipped with a grid frame, a scattering roller frame and a vibration motor. The grid frame pre-disperses the powder added to the storage box, and the scattering roller frame rotates synchronously with the first feeding auger shaft. The rotating scattering roller frame scatters the powder in the storage box to prevent the powder from agglomerating and improve the powder feeding effect. The vibration motor drives the receiving hopper to vibrate, so that the powder in the receiving hopper shakes, and the powder is better dropped from the drop pipe into the second powder feeding pipe to prevent the powder from blocking the drop pipe. This solves the problem that the powder storage structure of the existing powder feeding device does not have a scattering structure, the powder is easy to agglomerate, resulting in blockage in the powder feeding process and reducing the powder feeding effect.

[0026] 3. Compared with the existing powder feeding device, this powder feeding device and powder feeding method for laser cladding are equipped with a connecting flange, an inspection plate, a connecting head and a threaded connecting hole. The connecting flange connects the two first powder feeding pipes. By changing the length of the first powder feeding pipe, the working height of the powder feeding device is changed. The connecting head is aligned with the threaded connecting hole and inserted for connection. The two second feed auger shafts are assembled and used. The length of the second feed auger shaft is also increased, and changes synchronously with the length of the first powder feeding pipe. The powder feeding requirements at different heights can be met, the use effect of the powder feeding device is improved, and the problem of the fixed length of the powder feeding pipe of the existing powder feeding device, which limits the working range of the powder feeding device and reduces the practicality of the powder feeding device.

[0027] 4. Compared with the existing powder feeding device, this powder feeding device for laser cladding and its powder feeding method are equipped with a support seat, an anti-skid shock-absorbing pad, a walking wheel assembly and a hydraulic cylinder. The support seat supports the storage box and fixes the powder feeding device. The anti-skid shock-absorbing pad can play a shock-absorbing role when the powder feeding device is working, thereby improving the fixing stability of the powder feeding device. The hydraulic cylinder drives the walking wheel assembly to rise and fall, changes the height of the walking wheel assembly, and contacts the walking wheel assembly with the ground. With the help of the walking wheel assembly, the powder feeding device is conveniently moved, which solves the problem that the existing powder feeding device has no moving structure, the powder feeding device cannot be moved during use, and the practicality of the powder feeding device is reduced.
