Description

Technical Field

[0001] This utility model relates to the field of laser cladding technology, and in particular to a laser cladding preheating device. Background Technology

[0002] Laser cladding, also known as laser bonding or laser coating, is a novel surface modification technology. It involves adding cladding material to the surface of a substrate and using a high-energy-density laser beam to fuse the material together with a thin layer on the substrate surface, forming a metallurgically bonded cladding layer on the substrate surface. The cladding layer has low dilution but strong adhesion, exhibiting a metallurgical bond with the substrate. This can significantly improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance, or electrical properties of the substrate material surface, thereby achieving the purpose of surface modification or repair.

[0003] One issue that cannot be ignored is that some materials require preheating before cladding. Preheating can reduce the thermal stress of the material, reduce the generation of cracks and deformation, and improve the quality of the cladding layer. However, existing preheating and heat preservation devices have a small preheating range on the workpiece surface during use, which can easily lead to a small heating range on the workpiece, thereby affecting the preheating efficiency of the workpiece and reducing the cladding efficiency. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0024] See Figure 1 and Figure 2 This utility model provides a laser cladding preheating device, comprising:

[0025] The base 1 and the support body 2 are provided. A first fixing module and a second fixing module are respectively provided at both ends of the surface of the base 1. The support body 2 is provided on the surface of the base 1 and is located between the first fixing module and the second fixing module. A laser head 3 is provided on the side of the support body 2 close to the surface of the base 1. A preheating module is also provided on the periphery of the support body 2.

[0026] The preheating module includes a mounting rod 4, a longitudinal motor 5, a first reciprocating lead screw 6, and a clamping insulation plate 7. One end of the mounting rod 4 is fixedly connected to the periphery of the support body 2, and the other end is fixedly provided with a clamping body 8. The clamping body 8 has a hollow part 9 at the end away from the mounting rod 4. The fixed end 701 of the clamping insulation plate 7 is inserted into the hollow part 9. The longitudinal motor 5 is located at the top of the hollow part 9, and the output end of the longitudinal motor 5 is connected to the first reciprocating lead screw 6. The first reciprocating lead screw 6 is arranged to pass through the clamping body 8 and the fixed end 701 of the clamping insulation plate 7 in sequence. The clamping end 702 of the clamping insulation plate 7 away from the fixed end 701 is provided with a heating wire 10 arranged opposite to it.

[0027] See Figures 1 to 3In this embodiment, a first fixing module and a second fixing module are used to clamp and fix the material to be processed. A longitudinal motor 5 and a first reciprocating lead screw 6 work together to move the clamping insulation plate 7 vertically, allowing it to be adjusted and maintained in a suitable position. The heating wire 10 at the fixed end 701 of the clamping insulation plate 7 preheats the material to be processed. This laser cladding preheating device has a simple structure and can achieve preheating before laser cladding processing, reducing the generation of cracks and deformation and improving the cladding efficiency of the workpiece.

[0028] See Figure 1 and Figure 2 In another embodiment, the first fixing module includes:

[0029] The first fixing block 11 is located at any end of the surface of the base 1, and a rotating chuck 12 is provided at the end of the first fixing block 11 near the second fixing module.

[0030] By setting a rotary chuck 12, the material to be processed can be rotated while being held in place.

[0031] See Figure 1 and Figure 2 In another embodiment, the second fixing module includes:

[0032] The second fixing block 13 is located at the other end of the surface of the base 1. The second fixing block 13 has a pin 14 at one end near the first fixing block 11 and a handwheel 15 at the other end away from the first fixing block 11. The pin 14 and the handwheel 15 are connected through the second fixing block 13.

[0033] The left and right positions of the ejector pin 14 can be controlled by the handwheel 15, which makes it convenient to clamp materials of different lengths.

[0034] See Figure 1 and Figure 2 In another embodiment, it further includes:

[0035] The upper surface of the base 1 is also provided with a movable groove 16, and a second reciprocating lead screw 17 is provided in the movable groove 16. Either end of the second reciprocating lead screw 17 passes through the support body 2 and is connected to the output end of the horizontal motor 18.

[0036] With the above settings, the horizontal motor 18 can be used to start and drive the second reciprocating screw 17 to rotate, thereby driving the support body 2 to perform lateral displacement, so as to achieve complete processing of the material.

[0037] See Figure 3 In another embodiment, the heating wire 10 is a quartz heating tube.

[0038] Quartz heating tubes are characterized by high temperature resistance, corrosion resistance, and high electrothermal conversion efficiency. They are also relatively small in size, but their power can reach up to 1KW depending on the needs, resulting in better preheating effects.

[0039] In use, this invention utilizes a rotating chuck 12 to clamp the workpiece at one end and a pin 14 at the other to hold it in place. A longitudinal motor 5 drives a first reciprocating screw 6 to move the clamping insulation plate 7 vertically, adjusting and maintaining it in a suitable position. Then, the heating wire 10 generates heat, and a transverse motor 18 drives the first reciprocating screw 6, which in turn moves the support rod, achieving lateral displacement of the preheating structure and the laser head 3. Finally, the chuck rotates to process the workpiece. This laser cladding preheating device has a simple structure, enabling preheating before laser cladding, reducing cracks and deformation, and improving workpiece cladding efficiency.
