Description

Technical Field

[0001] This invention relates to the technical field of laser cladding, and specifically to a laser cladding machine with ultrasonic forging function. Background Technology

[0002] Laser cladding, also known as laser welding or laser coating, is a novel surface modification technology. It involves adding a cladding material to the surface of a substrate and then using a high-energy-density laser beam to fuse the material with a thin layer on the substrate surface, thus forming a metallurgically bonded cladding layer.

[0003] Laser cladding is a complex physical, chemical, and metallurgical process, a surface modification technique highly sensitive to cracks. The rapid heating by the laser beam completely melts the metal powder, and the heat cannot be transferred quickly enough, resulting in a substrate temperature much lower than the cladding layer temperature. This creates a large temperature gradient between the cladding layer and the substrate material. During the subsequent rapid solidification process, there is not enough liquid to replenish it. The resulting temperature gradient difference, along with the difference in the coefficients of thermal expansion between the cladding and substrate materials, causes inconsistent volume shrinkage between the cladding layer and the substrate. Generally, the shrinkage rate of the cladding layer is greater than that of the substrate material. The cladding layer is constrained by the surrounding environment (the cold substrate), thus forming residual tensile stress within the cladding layer. The magnitude of this stress is related to the hardness of the substrate material. In addition, solid metals also experience structural stress due to phase transformation during cooling.

[0004] When the combined stress exceeds the material's strength limit, cracks will occur in weak areas of the workpiece, such as pores and inclusions. Residual stress generated during laser cladding is the root cause of cracks in the cladding layer. Therefore, reducing or eliminating residual stress during the cladding process is the most important method to suppress cracks in the laser cladding layer.

[0005] Therefore, developing efficient and reliable stress homogenization technology within the micro-region of the laser cladding pool, starting from regulating the stress field of the cladding layer, is the key and effective way to solve the problem of laser cladding cracks. Summary of the Invention

The limiting blocks are hemispherical and contact the upper and lower surfaces of the rotating plate.

[0013] Preferably, the clamping mechanism includes positioning blocks, clamping bars, a second motor, and pressure bars. A pair of positioning blocks are symmetrically connected to the upper side of the rotating plate, and a positioning post is centrally located on the upper side of each positioning block. A pair of guide rails are symmetrically connected to the upper side of the rotating plate, and a slider is slidably connected to the guide rails. A slide plate is horizontally connected to the upper side of the slider. A pair of clamping bars are fixed to the upper sides of the two slide plates. The second motor is coaxially connected to the center of the rotating plate, vertically upward, and has a rotating bar installed at its output end. A pair of hinge bars are symmetrically hinged at both ends of the rotating bar, and the other end of each hinge bar is connected to an adjacent slide plate. A pair of guide rails arranged in a " / " pattern are symmetrically connected to both sides of the guide rails, and sliders are slidably connected to the guide rails. A slide plate is horizontally connected to the upper side of the slider, and the outer end of the slide plate is connected to... The mounting plates are of the type described above. The clamping strips are provided in two pairs and are correspondingly connected to the upper side of each mounting plate. The clamping strips are arc-shaped structures. Electric heating tubes are inserted into both ends of the heating strips. The inner end of the second guide rail is connected to a fixed plate. The inner end of the second sliding plate is connected to a "U"-shaped movable plate. A pair of compression springs are connected between adjacent fixed plates and movable plates. The rotating plate is rotatably connected to a mounting shaft on the side of the fixed plate, and a mounting wheel is connected to the upper end of the mounting shaft. The rotating plate is rotatably connected to a mounting shaft between the first and second guide rails, and a mounting wheel is connected to the upper end of the mounting shaft. A steel wire rope is connected between the first and second sliding plates, and the steel wire rope is constrained into a "Z" shape by the mounting wheel.

[0014] Preferably, the forging mechanism includes a first fixed plate, a first hydraulic cylinder, a second fixed plate, a second hydraulic cylinder, a lifting plate, and an amplitude transformer. The first fixed plate is vertically connected to the upper side of the mounting plate. The first hydraulic cylinder is horizontally connected inward to the upper part of the first fixed plate, and the second fixed plate is vertically connected to the end of the piston rod of the first hydraulic cylinder. The second hydraulic cylinder is vertically connected downward to the second fixed plate, and the lifting plate is horizontally connected to the end of the piston rod of the second hydraulic cylinder. A connecting plate is provided parallel to the side of the lifting plate, and several connecting strips are vertically connected to the side of the lifting plate.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. Positioning, clamping, and pressing the impeller. Place the impeller ring horizontally on top of the positioning blocks on both sides, and insert the positioning pins on both sides into the mounting holes on the left and right sides of the ring. Then, the motor drives the two clamping bars to move closer together, thus clamping the front and rear sides of the impeller ring. At the same time, the sliding plates that are moving closer together, pulled by the steel cables on both sides, will drive the sliding plates and pressing bars on both sides to move closer together, thus pressing the upper side of the impeller ring. During the pressing process, the impeller is heated by the heating strip.

[0019] 2. Laser cladding and ultrasonic forging of the impeller. A cladding layer is formed on the upper surface of the blades along the path of the hydraulic cylinder using a laser cladding head. Then, the linkage between hydraulic cylinders one and two drives the forging head to approach the impeller and move to the upper side of a certain blade, with two guide bars tightly attached to the sides of the blade. As the piston rod of hydraulic cylinder one continues to extend, the forging head slides over the cladding layer on the top surface of the blade. During this process, the cladding layer is forged by the high-frequency vibrating forging head to reduce or eliminate residual stress generated during the cladding process and refine the grains of the cladding layer.

[0041] In this embodiment, the forging mechanism 30 includes a first fixed plate 301, a first hydraulic cylinder 302, a second fixed plate 303, a second hydraulic cylinder 304, a lifting plate 305, and an amplitude transformer 311. The first fixed plate 301 is vertically connected to the upper side of the mounting plate 101. The first hydraulic cylinder 302 is horizontally connected inward to the upper part of the first fixed plate 301, and the second fixed plate 303 is vertically connected to the end of the piston rod of the first hydraulic cylinder 302.

A pair of guide posts 315 are vertically connected to the outer side of the second fixing plate 303. The guide posts 315 are slidably connected to the first fixing plate 301 through a guide sleeve 316.

[0042] In this embodiment, a rubber pad 207 is attached to the inner wall of the clamping strip 206. Adding the rubber pad 207 increases the friction between the clamping strip 215 and the impeller 50.

[0043] In this embodiment, an arc-shaped heating strip 216 is connected to the upper side of the pressing strip 215, and electric heating tubes 217 are inserted at both ends of the heating strip 216. By adding the above structure, the hot heating strip 216 can be used to heat the impeller 50 during the pressing process, thus avoiding the excessively rapid cooling of the cladding layer on the impeller 50.

[0044] In practical applications, this laser cladding machine with ultrasonic forging function includes the following tasks:

[0045] Step 1: Place the wheel ring 501 on the impeller 50 horizontally on the upper side of the positioning blocks 201 on the left and right sides, and insert the positioning pins 202 on the left and right sides into the mounting holes 501a on the left and right sides of the wheel ring 501. Then, the motor 208 drives the two clamping bars 206 to move closer to each other, thereby clamping the front and rear sides of the wheel ring 501 on the impeller 50. At the same time, the sliding plate 205, which moves closer to each other, will be pulled by the steel wire ropes 225 on both sides, which will drive the sliding plate 213 and the pressing bar 215 on both sides to move closer to each other, thereby pressing the upper side of the wheel ring 501 on the impeller 50. During the pressing, the impeller 50 is heated by the heating bar 216.

[0046] Step 2: A cladding layer is formed on the upper surface of the blade 502 along the path of the hydraulic cylinder 302 by the laser cladding head 40. Then, the linkage between the hydraulic cylinder 302 and the hydraulic cylinder 304 drives the forging head 313 to approach the impeller 50 and move to the upper side of a certain blade 502, and the two guide bars 314 are pressed against the two sides of the blade 502. As the piston rod of the hydraulic cylinder 302 continues to extend, the forging head 313 will slide over the cladding layer on the top surface of the blade 502. During this period, the cladding layer is forged by the high-frequency vibrating forging head 313 to reduce or eliminate the residual stress generated during the cladding process and refine the grains of the cladding layer.

[0047] Step 3: The forging head 313 is driven away from the impeller 50 and moved to the initial position by the linkage of hydraulic cylinder 302 and hydraulic cylinder 304.

[0048] Step 4: Drive the clamping mechanism 20 and impeller 50 to rotate a certain angle through the motors 103 on both sides, and then stop rotating;

[0049] Step 5: A cladding layer is formed on the upper surface of the blade 502 along the path of the hydraulic cylinder 302 by the laser cladding head 40. Then, the linkage between the hydraulic cylinder 302 and the hydraulic cylinder 304 drives the forging head 313 to approach the impeller 50 and move to the upper side of a certain blade 502, and the two guide bars 314 are pressed against the two sides of the blade 502. As the piston rod of the hydraulic cylinder 302 continues to extend, the forging head 313 will slide over the cladding layer on the top surface of the blade 502. During this period, the cladding layer is forged by the high-frequency vibrating forging head 313 to reduce or eliminate the residual stress generated during the cladding process and refine the grains of the cladding layer.

[0050] Step 6: The forging head 313 is driven away from the impeller 50 and moved to the initial position by the linkage of hydraulic cylinder 302 and hydraulic cylinder 304.

[0051] Step 7: Repeat steps 4 to 6. After the cladding layer on all blades 502 has been forged, the motor 208 drives the two clamping bars 206 and the two pairs of pressing bars 215 to move away from each other, thereby releasing the clamped and pressed impeller 50, and then taking away the impeller 50.

[0052] Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
