Description

Technical Field

[0001] The present invention relates to the technical field of saw blade processing, and specifically to a tooth welding machine for processing saw blades and a processing method thereof. Background Art

[0002] A saw blade is a steel strip with toothed edges, and the toothed edges are the main part, mainly used for cutting materials. Steel teeth can meet traditional needs, such as cutting wood. Current production activities also involve cutting metals. At this time, single steel teeth can no longer meet the requirements. The mainstream solution is to weld high-strength cutting heads on the saw teeth, and then cut metals through the cutting heads. However, new problems have arisen: the initial shape of the cutting head is cylindrical. Although this is convenient for welding, after welding, the cutting heads need to be polished one by one until their ends form triangles that are convenient for cutting. This increases a large amount of tooth grinding work and is particularly unfavorable for the efficient processing of saw blades. Based on this situation, how to make the shape of the cutting head meet the requirements of cutting work, reduce or even eliminate the tooth grinding work after the cutting heads are welded, and improve the processing efficiency of saw blades has increasingly become an urgent problem for relevant technical personnel to solve.

[0013] Furthermore, a processing method of a tooth welding machine for processing saw blades is as follows: (1) Place the saw blade to be processed horizontally on the first carrier plate and the lower clamping plate, and make the saw blade located between the front transmission wheels and the first limit bearing, and pour the cutter head to be welded into the vibration plate; (2) Start the first cylinder, the output end of the first cylinder pushes the first push block until the first push block contacts the saw blade, rotate the first rotating wheel or the second rotating wheel, and under the sliding limit of the first slide rail on the first slider, the first manual screw pushes the first long plate to move toward the first carrier plate until the side of the roller contacts the saw blade. At this time, the first push block, the roller, and the first limit bearing stabilize the saw blade; (3) Start the second cylinder. The output end of the second cylinder pushes the lifting plate downward until the upper clamping plate and the lower clamping plate clamp the saw blade. Start the first motor. The output shaft of the first motor drives the first electric screw rod to rotate. Through the sliding limit of the third slide rail on the third slider, the first electric screw rod drives the first moving seat, the carrier plate, the clamping part, and the saw blade as a whole to move towards the welding part. When the first moving seat reaches the end point of the stroke of the first electric screw rod, the saw blade moves into place. The output end of the second cylinder resets, and the output shaft of the first motor reverses until the first moving seat returns to the starting point of the stroke of the first electric screw rod, preparing for the next clamping and conveying of the saw blade; (4) Rotate the third runner. Due to the rotational setting of the rotating seat and the rotational connection between the second manual screw rod and the rotating seat, the second manual screw rod pushes the rotating plate to rotate to an appropriate angle. During this process, the sliding connection between the sliding rod and the sliding groove keeps the rotation of the rotating plate stable; (5) The vibrating disk vibrates continuously, causing the tool heads to move to the blanking plate one by one through the straight channel and the curved channel. During this process, the tool heads maintain sliding contact with the limiting grooves, causing the tool heads to fall on the blanking plate at the most convenient welding angle. Start the second motor. The output shaft of the second motor drives the second electric screw rod to rotate. Through the sliding limit of the fourth slide rail on the fourth slider, the second electric screw rod drives the third moving seat and the carrier seat as a whole to move towards the welding part. The push plate makes a preliminary push on the tool heads on the blanking plate. Start the third cylinder. Through the sliding limit of the fifth slide rail on the fifth slider, the output end of the third cylinder pushes the second moving seat towards the welding part. The push plate makes a further push on the tool heads on the blanking plate. After the above two-sided push, the tool heads move to the surface of the lower welding plate and abut against the welding surface of the saw blade teeth; (6) Start the fourth cylinder. The output end of the fourth cylinder pushes the upper welding plate downward until both the upper welding plate and the lower welding plate are in contact with the saw blade. The welding agent is applied to the welding surface of the saw blade, causing the upper welding plate and the lower welding plate to start working. Then, the tool heads can be welded to the welding surface of the saw blade teeth through the upper welding plate, the lower welding plate, and the welding agent. After welding is completed, reset the output end of the fourth cylinder; (7) Rotate the fourth runner. The third manual screw rod pushes the fourth moving seat and the folding plate as a whole to translate. Through the sliding limit of the sixth slide rail on the sixth slider and the sliding limit of the seventh slide rail on the seventh slider, move the second vision sensor to an appropriate position, tighten the positioning bolts, and stably position the sixth slider and the seventh slider. The first vision sensor detects whether the tool head is accurately abutted against the welding surface, and the second vision sensor detects whether the welding is qualified; (8) The saw blade is conveyed backward towards the rear conveyor wheel through the auxiliary conveying part, so that the welded part of the saw blade moves between the second limit bearing and the coil on the second carrier plate. Start the fifth cylinder, and the output end of the fifth cylinder pushes the second push block. Start the sixth cylinder, and the output end of the sixth cylinder pushes the third push block until the second push block and the third push block come into contact with the saw blade. Rotate the fifth runner or the sixth runner. Under the sliding limit of the ninth slide rail on the ninth slider, the fourth manual screw rod pushes the second long plate to translate towards the second carrier plate until the side of the roller comes into contact with the saw blade. At this time, the second push block, the third push block, and the roller stably limit the saw blade. (9) Rotate the seventh runner. Under the sliding limit of the tenth slide rail on the tenth slider, the fifth manual screw rod pushes the fifth moving seat to translate until the tempering device moves to a proper position. Start the tempering device, and the coil is energized to heat up, and the continuously passing saw blade is tempered to increase the strength of the saw blade. The saw blade after the tempering treatment is exported through the rear conveyor wheel.

[0014] The beneficial effects of a tooth welding machine for processing saw blades and its processing method of the present invention are as follows: 1. The staff only needs to pour the cutter head processed into an ideal shape into the vibrating disk, and the cutter head can be automatically conveyed to the welding surface of the saw blade teeth. In this way, not only does the shape of the cutter head meet the requirements of cutting work, but also there is no need for the tooth grinding work after the cutter head is welded, effectively improving the processing efficiency of the saw blade. 2. The main conveying part and the auxiliary conveying part effectively ensure the stable conveying of the saw blade, the feeding part effectively ensures the stable and accurate conveying of the cutter head, the first limiting part, the second limiting part, the first longitudinal limiting part, and the second longitudinal limiting part effectively ensure the stable limiting during the conveying process of the saw blade, and the first vision sensor and the second vision sensor effectively ensure the continuous monitoring of the welding quality, thereby effectively ensuring the tooth welding quality. 3. The first limiting part and the second limiting part effectively meet the limiting requirements for saw blades of different specifications. The rotational design of the feeding plate and the pushing of the cutter head by the pushing plate effectively meet the conveying requirements of the cutter head adapted to saw blades of different specifications, thereby effectively expanding the applicable range of this tooth welding machine.

[0028] Further, a processing method of a tooth welding machine for processing saw blades is as follows: (1)Place the saw blade 10 to be processed horizontally on the first carrier plate 20 and the lower clamping plate 34, and position the saw blade 10 between the front conveyor wheels 13 and between the first limit bearings 22. Pour the cutting tips 53 to be welded into the vibrating bowl 52. (2)Start the first cylinder 16. The output end of the first cylinder 16 pushes the first push block 15 until the first push block 15 contacts the saw blade 10. Rotate the first runner 24 or the second runner 28. Under the sliding limit of the first slide rail 29 on the first slider 30, the first manual screw 19 pushes the first long plate 27 to translate towards the first carrier plate 20 until the side of the roller 17 contacts the saw blade 10. At this time, the first push block 15, the roller 17, and the first limit bearings 22 stably limit the saw blade 10. (3)Start the second cylinder 38. The output end of the second cylinder 38 pushes the lifting plate 37 to move down until the upper clamping plate 36 and the lower clamping plate 34 clamp the saw blade 10. Start the first motor 39. The output shaft of the first motor 39 drives the first electric screw 41 to rotate. Under the sliding limit of the third slide rail 43 on the third slider 44, the first electric screw 41 drives the first moving seat 42, the carrier plate, the clamping part 12, and the saw blade 10 as a whole to move towards the welding part 7. When the first moving seat 42 reaches the end of the stroke of the first electric screw 41, the saw blade 10 moves into place. The output end of the second cylinder 38 resets, and the output shaft of the first motor 39 reverses until the first moving seat 42 returns to the starting point of the stroke of the first electric screw 41, preparing for the next clamping and conveying of the saw blade 10. (4)Rotate the third runner 49. Due to the rotational setting of the rotating seat 109 and the rotational connection between the second manual screw 110 and the rotating seat 109, the second manual screw 110 pushes the rotating plate 59 to rotate to an appropriate angle. During this process, the sliding connection between the slide bar 48 and the chute 46 keeps the rotation of the rotating plate 59 stable. (5)The vibrating bowl 52 vibrates continuously, causing the cutting tips 53 to move to the blanking plate 116 one by one through the straight track 51 and the curved track 50. During this process, the cutting tips 53 keep sliding contact with the limit groove 57, so that the cutting tips 53 fall on the blanking plate 116 at the most convenient welding angle. Start the second motor 58. The output shaft of the second motor 58 drives the second electric screw 69 to rotate. Under the sliding limit of the fourth slide rail 60 on the fourth slider 61, the second electric screw 69 drives the third moving seat 67 and the carrier seat 62 as a whole to move towards the welding part 7. The push plate 54 makes a preliminary push on the cutting tips 53 on the blanking plate 116. Start the third cylinder 68. Under the sliding limit of the fifth slide rail 63 on the fifth slider 64, the output end of the third cylinder 68 pushes the second moving seat 65 to move towards the welding part 7. The push plate 54 makes a further push on the cutting tips 53 on the blanking plate 116. After the above two-sided pushes, the cutting tips 53 move to the surface of the lower welding plate 80 and contact the welding surface 56 of the saw teeth of the saw blade 10. (6) Start the fourth cylinder 78. The output end of the fourth cylinder 78 pushes the upper welding plate 79 downward until both the upper welding plate 79 and the lower welding plate 80 are in contact with the saw blade 10. A welding agent is applied to the welding surface 56 of the saw blade 10, causing the upper welding plate 79 and the lower welding plate 80 to start working. Then, the cutter head 53 can be welded to the welding surface 56 of the saw teeth of the saw blade 10 through the upper welding plate 79, the lower welding plate 80, and the welding agent. After welding is completed, reset the output end of the fourth cylinder 78; (7) Rotate the fourth runner 83. The third manual screw 84 pushes the fourth moving seat 85 and the folding plate as a whole to translate. Through the sliding limit of the sixth slide rail 71 on the sixth slider 72 and the sliding limit of the seventh slide rail 75 on the seventh slider 76, move the second vision sensor 73 to a suitable position, tighten the positioning bolt 77, stably position the sixth slider 72 and the seventh slider 76. The first vision sensor 74 detects whether the cutter head 53 and the welding surface 56 are in precise contact, and the second vision sensor 73 detects whether the welding is qualified; (8) Through the auxiliary conveyor 6, convey the saw blade 10 in the direction of the rear conveyor wheel 9, so that the welded part of the saw blade 10 moves between the second carrier plate 86, the second limit bearing 101, and the coil 102. Start the fifth cylinder 87, and the output end of the fifth cylinder 87 pushes the second push block 88. Start the sixth cylinder 90, and the output end of the sixth cylinder 90 pushes the third push block 89 until the second push block 88 and the third push block 89 are in contact with the saw blade 10. Rotate the fifth runner 95 or the sixth runner 98. Under the sliding limit of the ninth slide rail 93 on the ninth slider 92, the fourth manual screw 99 pushes the second long plate 96 to translate towards the second carrier plate 86 until the side of the roller 17 is in contact with the saw blade 10. At this time, the second push block 88, the third push block 89, and the roller 17 stably limit the saw blade 10; (9) Rotate the seventh runner 104. Under the sliding limit of the tenth slide rail 105 on the tenth slider 103, the fifth manual screw 114 pushes the fifth moving seat 115 to translate until the tempering device 106 is moved to a suitable position. Start the tempering device 106, and the coil 102 is energized to heat up, performing tempering treatment on the continuously passing saw blade 10 to increase the strength of the saw blade 10. The saw blade 10 after tempering treatment is exported through the rear conveyor wheel 9.
