Description

Technical Field

[0001] The present invention relates to the technical field of metal coatings, and in particular to a band saw blade coating device and method. Background Art

[0002] A band saw blade is a tool used to cut metal and other shaped materials. It consists of a tough, sharp-toothed saw blade stretched in a frame and is usually used with a band saw machine. When the band saw blade is cutting metal workpiece materials at high speed, a large amount of cutting heat will be generated, which can easily cause the saw teeth to soften and affect the performance of the saw teeth. In addition, when cutting difficult-to-process materials, the saw teeth are prone to chipping and severe wear, which seriously affects the sawing efficiency and quality, and increases costs. Therefore, the band saw blade coating process is often used to greatly improve the comprehensive performance of the saw blade and improve the high temperature resistance and wear resistance of the band saw blade.

[0003] Physical vapor deposition (PVD) and electrochemical deposition (electroplating) technology are often used in the coating processing of band saw blades. A hard coating with a hardness of up to 3000HV is deposited on the surface of the saw blade teeth. The hardness of ordinary high-speed steel saw teeth is only 1000HV, and the hardness of cemented carbide saw teeth is only 600HV. This hard coating is like a protective layer that protects the saw teeth. It has the functions of high hardness, friction reduction, and heat insulation, which can greatly improve the life of the band saw blade.

[0004] When existing band saw blade coating equipment is coating the band saw blade, it is often necessary to sandblast the saw blade before coating to clean the saw blade surface and improve the coating quality. When the hard coating is deposited on the surface of the band saw blade, the hard coating deposited on the surface of the band saw blade after the sandblasting will have a small uneven area, which will affect the smoothness of the subsequent driving of the band saw blade and the band saw machine, and affect the cutting performance of the band saw blade. Therefore, a band saw blade coating equipment and method are proposed. Summary of the invention

When the corrector and the cutting molybdenum wire collide with sparks, the temperature difference between the upper and lower sides of the corrector is used to judge the difference between the upper and lower contact surfaces of the corrector and the cutting molybdenum wire, thereby judging whether the verticality of the cutting molybdenum wire that is currently sparking meets the requirements, and the accuracy of judgment is improved in combination with the size of the electric spark;

[0028] 6. The present invention sets a positioning guide plate, so that when the band saw blade body moves into the interior of the surface treatment box, the positioning electric push rods on both sides will drive the positioning guide plates to merge on both sides of the top of the band saw blade body, guiding and correcting the moving trajectory of the band saw blade body, so that the band saw blade body can maintain a relatively vertical state, thereby ensuring that the band saw blade body and the cutting molybdenum wire are kept parallel during surface treatment, thereby ensuring the treatment effect.

[0044] The surface treatment component is used to perform surface treatment on both sides of the band saw blade body 8 after coating treatment, such as Figure 2 As shown, the surface treatment assembly includes two wire cutting devices 9 installed inside the surface treatment box 4, such as Figure 3 As shown, two wire cutting devices 9 are staggered on both sides of the band saw blade body 8, and a horizontally arranged upper telescopic cantilever 10 and a lower telescopic cantilever 12 are fixedly installed on one side of the wire cutting device 9 close to the band saw blade body 8, as shown in FIG. Figure 5 As shown, the upper telescopic cantilever 10 and the lower telescopic cantilever 12 are distributed from top to bottom and are located on the same vertical plane. Figure 6 As shown, the telescopic ends of the upper telescopic cantilever 10 and the lower telescopic cantilever 12 are respectively fixedly installed with an upward line arm 11 and a downward line arm 13, and a cutting molybdenum wire 14 is driven and installed between the upward line arm 11 and the downward line arm 13. The two cutting molybdenum wires 14 are respectively located on both sides of the band saw blade body 8, as shown in FIG. Figure 5 As shown, a middle telescopic cantilever 15 is fixedly installed on one side of the wire cutting device 9, and a conductive baffle 16 is fixedly installed on the telescopic end of the middle telescopic cantilever 15. The positions of the two conductive baffles 16 correspond to the positions of the cutting molybdenum wires 14 on the opposite sides. In this embodiment, the wire cutting devices 9 and their accessories on both sides are staggered, that is, the two cutting molybdenum wires 14 are distributed on both sides of the band saw blade body 8 but staggered with each other, and the cutting molybdenum wire 14 on one side of the band saw blade body 8 corresponds to the position of the conductive baffle 16 on the other side of the band saw blade body 8, as shown in FIG. Figure 3As shown, the same emulsion recovery box 17 is fixedly installed between the two wire cutting devices 9, and the emulsion recovery box 17 is located at the bottom of the band saw blade body 8; specifically, by setting a surface treatment component, after the band saw blade body 8 is sent into the surface treatment box 4, it will pass through the cutting molybdenum wires 14 on both sides. Before that, the cutting molybdenum wires 14 on both sides will be moved in advance toward the position of the moving trajectory of the band saw blade body 8 under the drive of the upper telescopic cantilever 10, the upward line arm 11 and the lower telescopic cantilever 12, and the downward line arm 13, until the two cutting molybdenum wires 14 are on both sides of the band saw blade body 8. At the same time, the conductive baffles 16 on both sides will also move to the two sides of the band saw blade body 8 under the drive of the middle telescopic cantilever 15, and correspond to the position of the cutting molybdenum wire 14 on the opposite side. When the band saw blade body 8 passes through the two groups of cutting molybdenum wires 14 and the conductive baffles 16 When the upper telescopic cantilever 10, the lower telescopic cantilever 12 and the middle telescopic cantilever 15 drive the cutting molybdenum wire 14 and the conductive baffle 16 on both sides to stick to the two sides of the band saw blade body 8, so that the conductive baffle 16 is connected to the positive electrode and the cutting molybdenum wire 14 is connected to the negative electrode, so that when the cutting molybdenum wire 14 and the conductive baffle 16 contact the band saw blade body 8, the cutting molybdenum wire 14 performs electric spark wire cutting on the surface of the band saw blade body 8, and as the band saw blade body 8 moves, the excess coating structure on the uneven areas on both sides of the band saw blade body 8 will be cut off, and slide into the emulsion recovery box 17 along with the emulsion flowing down from the upper wire arm 11, so that the two sides of the band saw blade body 8 are restored to flatness, and with the post-processing of the secondary sandblasting box 5 and the secondary cleaning box 6, the fatigue resistance and coating adhesion of the band saw blade body 8 are enhanced, and in the subsequent coordinated drive with the sawing machine, good smoothness is maintained.

[0045] like Figure 5 As shown, a horizontally arranged correction telescopic arm 18 is fixedly installed on one side of the wire cutting device 9 close to the band saw blade body 8, as shown in FIG. Figure 6As shown, the telescopic ends of the correction telescopic arms 18 are fixedly mounted with mounting frames 19, and the mounting frames 19 are internally provided with correctors 20, and the correctors 20 located on the same side correspond to the positions of the cutting molybdenum wires 14, and one side of the upward line arm 11 is fixedly mounted with correction taper heads 21 and micro motors 22 in sequence, and the output end of the micro motor 22 is drivingly connected to the correction taper head 21; specifically, by providing the corrector 20, before the cutting molybdenum wire 14 is used to perform surface treatment on the band saw blade body 8, the correction telescopic arm 18 first drives the mounting frame 19 to move toward the cutting molybdenum wire 14 The cutting molybdenum wire 14 is connected to the negative electrode and the corrector 20 is connected to the positive electrode until the two are in contact, so that electric sparks appear at the contact position between the cutting molybdenum wire 14 and the corrector 20, and then the verticality of the cutting molybdenum wire 14 is judged according to the size of the electric sparks generated by the upper and lower touches of the corrector 20. If the sizes are inconsistent, the micro motor 22 drives the correction taper head 21 and the upward line arm 11 to adjust the verticality of the cutting molybdenum wire 14 until the upper and lower sparks are consistent in size, thereby ensuring that the cutting molybdenum wire 14 remains relatively parallel to the side of the band saw blade body 8, thereby ensuring the effectiveness of the surface treatment.

[0046] like Figure 6 As shown, a mounting claw 23 is fixedly installed on the side wall of the mounting frame 19, and the corrector 20 is clamped inside the mounting claw 23. In the present embodiment, the mounting claw 23 and the side wall of the corrector 20 are provided with matching assembly holes for inserting fastening bolts; specifically, by providing the mounting claw 23, the corrector 20 can be clamped on the mounting claw 23 by fastening bolts, thereby maintaining a detachable connection relationship between the mounting claw 23 and the mounting frame 19, so that when electrolytic corrosion, rust, damage, etc. occur on the surface of the corrector 20, the corrector 20 can be adjusted in position or directly replaced to ensure the correction effect of the corrector 20.

[0047] like Figure 6 As shown, temperature sensors 24 are fixedly installed on the top and bottom of the mounting frame 19, and the two temperature sensors 24 are in contact with the upper and lower sides of the corrector 20 respectively; specifically, by setting the temperature sensors 24, the two temperature sensors 24 can respectively sense and transmit the temperature data of the upper and lower sides of the corrector 20 in real time. When the corrector 20 and the cutting molybdenum wire 14 collide with sparks, obvious temperature changes will appear on the upper and lower sides of the corrector 20, and then the temperature difference between the upper and lower sides of the corrector 20 can be used to judge the difference between the upper and lower contact surfaces of the current corrector 20 and the cutting molybdenum wire 14, thereby judging whether the verticality of the cutting molybdenum wire 14 that is currently colliding with sparks meets the requirements, and the accuracy of the judgment is improved in combination with the size of the electric spark.

[0048] like Figure 2As shown, both sides of the surface treatment box 4 are rotatably installed with an opening and closing door 25, and one side of the top of the opening and closing door 25 is provided with an observation window. The position of the observation window corresponds to the position of the corrector 20, and the top of the opening and closing door 25 is rotatably installed with a dark transparent plate 26 adapted to the observation hole; specifically, by setting the dark transparent plate 26, when manually observing the sparks between the corrector 20 and the cutting molybdenum wire 14, the dark transparent plates 26 on both sides can be buckled onto the observation windows on the opening and closing door 25, so that the dark transparent plates 26 absorb and block external light, reduce the interference of external light on the inside of the surface treatment box 4, and facilitate the observation of the sparks on both sides through the observation windows on the opening and closing door 25, and then judge the verticality.

[0049] like Figure 1 , Figure 2 As shown, a monitoring camera probe 27 is fixedly installed on the top of the surface treatment box 4, and one end of the monitoring camera probe 27 extends to the interior of the surface treatment box 4 and faces the two correctors 20; specifically, by setting the monitoring camera probe 27, the monitoring camera probe 27 can monitor the spark collision situation on both sides from the top of the interior of the surface treatment box 4 in real time, and then combine with external manual observation and internal temperature sensing to ensure the accuracy of the correction of the cutting molybdenum wire 14.

[0050] like Figure 3 , Figure 7 As shown, two first positioning columns 28 and two second positioning columns 29 are fixedly installed inside the surface treatment box 4. The two first positioning columns 28 and the second positioning columns 29 are respectively located on both sides of the band saw blade body 8. The first positioning column 28 is located between the emulsion recovery box 17 and the coating treatment box 3, and the second positioning column 29 is located between the emulsion recovery box 17 and the secondary sandblasting box 5. The top ends of the first positioning columns 28 and the second positioning columns 29 are fixedly installed with horizontally arranged positioning electric push rods 30, as shown in FIG. Figure 5 As shown, one end of the positioning electric push rod 30 is facing the band saw blade body 8 and is fixedly installed with a positioning guide plate 31. The two positioning guide plates 31 located at the same place are symmetrically distributed on both sides of the top of the band saw blade body 8. In the present embodiment, the positioning guide plate 31 is in an inverted "L" shape, covering the top and both sides of the band saw blade body 8; specifically, by setting the positioning guide plate 31, when the band saw blade body 8 moves to the inside of the surface treatment box 4, the positioning electric push rods 30 on both sides will drive the positioning guide plate 31 to move toward the band saw blade body 8 until they are merged on both sides of the top of the band saw blade body 8, so that the front and rear two groups of positioning guide plates 31 play a role in guiding and correcting the travel trajectory of the band saw blade body 8, so that the band saw blade body 8 maintains a relatively vertical state during travel, thereby ensuring that the band saw blade body 8 and the cutting molybdenum wire 14 are kept parallel to each other for surface treatment, thereby ensuring the treatment effect.

[0051] like Fig. 9 As shown, a band saw blade coating method comprises the following steps:

[0052] S1, the band saw blade body 8 is sent into the primary sandblasting box 1, and is subjected to sandblasting passivation treatment by the sandblasting equipment inside the primary sandblasting box 1;

[0053] S2, the band saw blade body 8 is sent into the primary cleaning box 2, and the ultrasonic cleaning machine inside the cleaning box 2 uses a metal cleaner to clean the surface of the band saw blade body 8, and then passes inert gas to air dry;

[0057] S6. Send the processed band saw blade body 8 into the winding box 7 for winding.

[0058] In summary: when the band saw blade coating equipment is in use, the band saw blade body 8 will be sent to the primary sandblasting box 1, the primary cleaning box 2, the coating treatment box 3, the surface treatment box 4, the secondary sandblasting box 5, the secondary sandblasting box 5 and the winding box 7 in sequence, firstly, it will be subjected to sandblasting passivation treatment in the primary sandblasting box 1, and then the surface of the band saw blade body 8 will be cleaned by the ultrasonic cleaning machine inside the primary cleaning box 2 using a metal cleaner, and then the inert gas will be introduced to air dry, and then the band saw blade body 8 will be sent to the coating treatment box 3 for multiple arc ion deposition, so that both sides of the band saw blade body 8 will obtain a multi-layer coating, and then the coated band saw blade body 8 will be sent to the surface treatment box 4 to perform wire cutting on the redundant coating structure in the uneven surface area, so that the surface of the band saw blade body 8 will be smooth, and ... The surface is restored to be flat, and then the band saw blade body 8 is sent to the secondary sandblasting box 5 for secondary sandblasting passivation, and then sent to the secondary cleaning box 6 for secondary cleaning and air drying. Finally, the processed band saw blade body 8 is sent to the winding box 7 for winding. By setting the surface treatment component, the band saw blade body 8 will pass between the cutting molybdenum wires 14 on both sides after being sent to the surface treatment box 4. Previously, the cutting molybdenum wires 14 on both sides will be driven by the upper telescopic cantilever 10, the upward line arm 11 and the lower telescopic cantilever 12, and the downward line arm 13 to move in advance toward the position of the moving track of the band saw blade body 8 until the two cutting molybdenum wires 14 are on both sides of the band saw blade body 8. At the same time, the conductive baffles 16 on both sides will also move under the drive of the middle telescopic cantilever 15 The upper telescopic cantilever 10, the lower telescopic cantilever 12 and the middle telescopic cantilever 15 drive the cutting molybdenum wires 14 and the conductive baffles 16 on both sides to be close to the two sides of the band saw blade body 8, so that the conductive baffles 16 are connected to the positive electrode and the cutting molybdenum wires 14 are connected to the negative electrode. When the cutting molybdenum wires 14 and the conductive baffles 16 contact the band saw blade body 8, the cutting molybdenum wires 14 perform electric spark wire cutting on the surface of the band saw blade body 8. As the band saw blade body 8 moves, the excess coating structure in the uneven areas on both sides of the band saw blade body 8 will be cut off and slide down to the emulsion return line along with the emulsion flowing down from the upper wire arm 11. In the receiving box 17, both sides of the band saw blade body 8 are restored to flatness, and with the post-processing of the secondary sandblasting box 5 and the secondary cleaning box 6, the fatigue resistance and coating adhesion of the band saw blade body 8 are enhanced, and in the subsequent coordinated driving with the sawing machine, good smoothness is maintained. By setting the corrector 20, before using the cutting molybdenum wire 14 to perform surface treatment on the band saw blade body 8, the correction telescopic arm 18 first drives the placement frame 19 to move toward the cutting molybdenum wire 14, and the cutting molybdenum wire 14 is connected to the negative electrode and the corrector 20 is connected to the positive electrode until the two are in contact, so that electric sparks appear at the contact position between the cutting molybdenum wire 14 and the corrector 20, and then the verticality of the cutting molybdenum wire 14 is judged according to the size of the electric sparks generated by the upper and lower touch of the corrector 20. If the sizes are inconsistent,The micro motor 22 drives the correction taper head 21 and the upward line arm 11 to adjust the verticality of the cutting molybdenum wire 14 until the upper and lower sparks are the same size, thereby ensuring that the cutting molybdenum wire 14 and the side of the band saw blade body 8 remain relatively parallel, ensuring the effectiveness of the surface treatment, and by providing the mounting claw 23, the corrector 20 can be clamped on the mounting claw 23 by the fastening bolt, thereby maintaining a detachable connection relationship between the mounting claw 23 and the mounting frame 19, so that when electrolytic corrosion, rust, damage, etc. occur on the surface of the corrector 20, the corrector 20 can be adjusted in position or directly replaced In order to ensure the correction function of the corrector 20, the temperature sensors 24 are set so that the two temperature sensors 24 can respectively sense and transmit the temperature data of the upper and lower sides of the corrector 20 in real time. When the corrector 20 and the cutting molybdenum wire 14 collide with sparks, obvious temperature changes will appear on the upper and lower sides of the corrector 20. Then, the temperature difference between the upper and lower sides of the corrector 20 can be used to judge the difference between the upper and lower contact surfaces of the current corrector 20 and the cutting molybdenum wire 14, so as to judge whether the verticality of the cutting molybdenum wire 14 that currently collides with sparks meets the requirements, and the accuracy of judgment is improved by matching the size of the electric spark. By setting the dark color The transparent plate 26 allows the dark transparent plates 26 on both sides to be buckled to the observation windows on the opening and closing door 25 when manually observing the sparks between the corrector 20 and the cutting molybdenum wire 14, so that the dark transparent plates 26 absorb and block external light, reduce the interference of external light on the inside of the surface treatment box 4, and facilitate observation of the sparks on both sides through the observation windows on the opening and closing door 25, and then judge the verticality. By setting the monitoring camera probe 27, the monitoring camera probe 27 can monitor the sparks on both sides from the top of the inside of the surface treatment box 4 in real time, and then compare with the external manual observation. , combined with the internal temperature induction, the accuracy of the correction of the cutting molybdenum wire 14 is ensured. By setting the positioning guide plate 31, when the band saw blade body 8 moves to the inside of the surface treatment box 4, the positioning electric push rods 30 on both sides will drive the positioning guide plate 31 to move toward the band saw blade body 8 until it merges on both sides of the top of the band saw blade body 8, so that the front and rear two groups of positioning guide plates 31 play a guiding and correcting role on the moving trajectory of the band saw blade body 8, so that the band saw blade body 8 maintains a relatively vertical state, thereby ensuring that the band saw blade body 8 and the cutting molybdenum wire 14 are kept parallel to each other for surface treatment, ensuring the treatment effect. ,
