Description

Technical Field

[0001] The invention belongs to the technical field of tool processing and relates to a tool laser cladding device. Background Art

[0002] As modern manufacturing industry continues to improve its requirements for processing efficiency and product quality, traditional tools often fail to meet the requirements in terms of wear resistance, impact resistance and service life when facing the cutting of high-strength and high-hardness materials. In order to improve tool performance and extend service life, various surface treatment technologies have emerged. Among them, laser cladding, as an advanced surface strengthening technology, has shown unique advantages in improving tool surface performance.

[0003] Laser cladding uses a high-energy laser beam to quickly melt the selected alloy powder or ceramic material and deposit it on the surface of the tool substrate to form a cladding layer with excellent physical and chemical properties. This technology can significantly improve the wear resistance, corrosion resistance and fatigue resistance of the tool, thereby greatly improving the working efficiency and service life of the tool. In particular, laser cladding treatment on the cutting edge can effectively enhance the cutting ability of the tool under extreme working conditions, reduce cutting edge wear, and improve cutting quality.

[0004] However, although laser cladding has brought a qualitative leap in tool surface performance, it also faces certain challenges in practical applications. A major problem is that after the tool edge is laser clad, due to the thickness of the cladding layer and possible unevenness, it is usually necessary to grind and sharpen the edge again to achieve the ideal cutting angle and edge sharpness. This process inevitably requires the removal of a large amount of cladding material, which is not only time-consuming and labor-intensive, but also leads to serious loss of cladding material. Summary of the invention

[0005] The object of the present invention is to provide a tool laser cladding device, which can immediately perform plastic treatment on the cladding part after the tool is laser clad, making it more convenient for subsequent grinding, effectively shortening the grinding time, and reducing the loss of cladding material.

[0006] In order to solve the above technical problems, the present invention provides a tool laser cladding device, comprising a base, a laser cladding machine body is arranged on one side of the base, a horizontal slide rail is arranged on the front side of the upper end of the base, a horizontal slider is slidably connected to the horizontal slide rail, a horizontal driving motor for driving the horizontal slider to slide is installed on the horizontal slide rail, a positioning plate is arranged on the upper end of the horizontal slider, and an electromagnet is arranged on one side of the positioning plate;

[0007] A vertical slide rail is upwardly arranged on the rear side of the upper end of the base, and a vertical slider is slidably connected to the vertical slide rail. A vertical driving motor for driving the vertical slider to slide is installed on the vertical slide rail, and a mounting plate is arranged on the front side of the vertical slide rail, and a rotating plate is rotatably connected to the front side of the mounting plate, and a driving motor for driving the rotating plate to rotate is installed on the mounting plate, and a laser cladding machine head located directly above the positioning plate is installed on the front side of the rotating plate, and the laser cladding machine head is connected to the main body of the laser cladding machine;

[0009] By adopting the above technical solution, when performing laser cladding of the tool, firstly, the tool is placed on the outer side of the positioning plate with the cutting edge facing upwards, and after the electromagnet is started, the electromagnet generates magnetism to attract the tool and firmly fix the tool on the outer side of the positioning plate;

[0010] Then the horizontal drive motor drives the horizontal slider to drive the tool to move horizontally, and the laser rangefinder detects the distance to the tool edge in real time to identify the shape of the tool edge. Then the vertical drive motor drives the laser cladding head to descend to a suitable position, and then the laser cladding head is started to perform laser cladding from one end of the tool edge.

[0011] During the cladding process, the horizontal drive motor drives the tool to move horizontally. After cladding, the middle pressure wheel cooperates with the side pressure wheel to roll the cladding part that has not yet cooled and formed, so that the cladding part has a V-shaped cross-section. During the cladding process, the laser rangefinder detects the change in distance from the cutting edge, and cooperates with the vertical drive motor to drive the laser cladding head to move up and down. The drive motor drives the laser cladding head to rotate, and finally the laser cladding head is clad along the shape of the tool cutting edge.

[0012] The present invention is further configured such that a laser rangefinder facing the positioning plate is provided on the front side of the mounting plate at a side of the laser cladding head away from the forming frame, the cross-section of the laser cladding head and the cross-section of the laser rangefinder are located in the same plane, and the laser cladding head and the laser rangefinder are in the same direction.

[0019] The present invention is further configured such that the middle pressure wheel and each side pressure wheel are made of ceramic material.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] First, when the laser cladding of the tool is performed, the present invention is equipped with two side pressure wheels and a middle pressure wheel on the rear side of the laser cladding machine head. After the laser cladding is performed, the side pressure wheels cooperate with the middle pressure wheel to roll the cladding part that has not yet cooled and formed to form a V-shaped cutting edge, which is convenient for subsequent cutting edge grinding processing. Only simple grinding is required, which can effectively shorten the grinding time, improve work efficiency, and effectively reduce the loss of cladding materials during grinding;

[0022] Secondly, the laser cladding machine head of the present invention can move up and down and rotate freely. With the cooperation of the laser rangefinder, the distance to the cutting edge of the tool can be detected in real time, so that it can be adaptively lifted and rotated according to the shape of the cutting edge, and always fit the cutting edge for cladding, which has a higher cladding effect;

[0023] Thirdly, the present invention can also adjust the bevel angle of the cutting edge as needed. The lifting threaded sleeve is driven up and down by rotating the motor, and the inclined connecting arm is pulled by the push-pull bar to rotate the corresponding angle, so that the inverted V-shaped angle formed between the side pressure wheel and the middle pressure wheel changes.

[0036] Working principle: When performing laser cladding of a tool, first place the tool with the cutting edge facing upward in the strip support groove 38, and after starting the electromagnet 37, the electromagnet 37 generates magnetism to attract the tool and firmly fix the tool on the outside of the positioning plate 36. According to the required bevel angle of the blade, start the rotary motor 76 to drive the lifting thread sleeve 78 up and down, and pull the inclined connecting arm 73 to rotate the corresponding angle through the push-pull bar 79, so that the angle between the side pressure wheel 74 and the middle pressure wheel 72 changes;

[0038] During the cladding process, the horizontal drive motor 34 drives the tool to move horizontally. After cladding, the middle pressure wheel 72 cooperates with the side pressure wheel 74 to roll the cladding part that has not yet cooled and formed, so that the cladding part has a V-shaped cross-section. During the cladding process, the laser rangefinder 8 detects the change in distance from the cutting edge, and cooperates with the vertical drive motor 44 to drive the laser cladding head 6 to move up and down, and the drive motor 54 drives the laser cladding head 6 to rotate, and finally the laser cladding head 6 is clad along the shape of the tool cutting edge.
