Description

Technical Field

[0001] This utility model belongs to the field of circular saw blade manufacturing technology, and specifically relates to a stress relief device for laser welding of circular saw blades. Background Technology

[0002] Circular saw blades are core tools in industrial cutting, widely used in wood processing, metal cutting, stone processing, and other fields. A circular saw blade consists of two parts: the base and the cutting head. During the welding of the cutting head to the base, the laser beam causes a rapid increase in local temperature within microseconds, generating high-temperature compressive stress around the molten pool. During the cooling phase, the molten metal solidifies and shrinks, constrained by the cold base, forming residual tensile stress. If this stress is not relieved, it can lead to cracks in the stress concentration areas of the circular saw blade under alternating loads.

[0003] Ultrasonic vibration stress relief technology is gradually becoming a key process to replace thermal aging due to its non-thermal processing characteristics and high efficiency. This process requires the circular saw blade to be rigidly fixed to the vibration platform to ensure energy transfer efficiency. However, the diameter of the central hole of different models of circular saw blades is different, and the positioning components of the circular saw blade need to be replaced according to the actual situation, which is quite troublesome. Utility Model Content

[0020] Please see Figures 1-8 As shown, this utility model is a stress relief device for laser welding of circular saw blades, including a base 1, a conveying component 2 on the top of the base 1, a supporting component 3 on the top of the conveying component 2, an adjusting component 4 inside the supporting component 3, a displacement component 5 on one side of the conveying component 2, and a stress relief component 6 on the other side of the conveying component 2.

Then the conveying component 2 is started, and the conveying component 2 drives the support component 3 and the circular saw blade to move until the support component 3 moves between the displacement component 5 and the stress relief component 6. Then the conveying component 2 stops moving and the displacement component 5 is started. The displacement component 5 pushes the support component 3 and the circular saw blade to move, so that the support component 3 and the circular saw blade are connected to the stress relief component 6. The stress relief component 6 is started to ultrasonically relieve the stress on the circular saw blade.

[0022] This utility model connects the support component 3 and the adjustment component 4. After the circular saw blade is placed on the outer surface of the support component 3, the adjustment component 4 inside the support component 3 is moved. The adjustment component 4 simultaneously drives the two sets of support members of the support component 3 to move. The two sets of support members of the support component 3 can move away from or closer to each other, so that the support component 3 can support and fix circular saw blades with different hole diameters. There is no need to replace the support component 3 during use, which is more convenient.

A conveying chain plate 206 is driven to the outer surface of the reducer 205. The conveying chain plate 206 rotates on the outer surface of the base 1.

[0024] Start the first motor 201. The output shaft of the first motor 201 drives the first pulley 202 to rotate. The first pulley 202 drives the second pulley 204 to rotate through the belt 203. The second pulley 204 drives the conveyor chain plate 206 to rotate on the outer surface of the base 1 through the reducer 205.

[0025] In one embodiment, the support assembly 3 includes a support plate 301, a connecting shaft 302 rotatably connected inside the support plate 301, a insertion groove 303 at one end of the connecting shaft 302, a circular plate 304 fixedly connected to the other end of the connecting shaft 302, a limiting block 305 fixedly connected to the outer surface of the connecting shaft 302, the limiting block 305 slidably connected inside the support plate 301, and a first support rod 306 and a second support rod 307 slidably connected inside the circular plate 304, with limiting bolts 308 threadedly connected inside both the first support rod 306 and the second support rod 307.

[0026] In one embodiment, the adjustment component 4 includes a gear 401 rotatably connected inside the circular plate 304. The outer surface of the gear 401 is respectively meshed with a first rack 402 and a second rack 403.

The outer surfaces of the first rack 402 and the second rack 403 are each provided with a sliding groove 404. A slide rail 405 is slidably connected inside the sliding groove 404. The slide rail 405 is fixedly connected inside the circular plate 304.

[0027] After placing the circular saw blade on the outer surfaces of the first support rod 306 and the second support rod 307, push the first support rod 306 to move. The first support rod 306 drives the first rack 402 to move. The first rack 402 drives the second rack 403 and the second support rod 307 to move through the gear 401. The first support rod 306 and the second support rod 307 move in opposite directions, so that the first support rod 306 and the second support rod 307 support the circular saw blade. Then rotate the limiting bolt 308 so that it passes through the first support rod 306 and the second support rod 307 and abuts against the circular plate 304 for fixation. At this time, the conveyor chain plate 206 can drive the circular plate 304 and the circular saw blade to move.

[0028] In one embodiment, the displacement component 5 includes a connecting frame 501, which is fixedly connected to the base 1. An electric push rod 502 is fixedly installed on the top of the connecting frame 501, and a push seat 503 is rotatably installed on the movable end of the electric push rod 502.

[0029] In one embodiment, the stress relief component 6 includes a bracket 601, on the outer surface of which a second motor 602 and an ultrasonic transducer 603 are fixedly mounted respectively. A plug shaft 604 is fixedly mounted on the output shaft end of the second motor 602, and an ultrasonic head 605 is fixedly connected to the outer surface of the ultrasonic transducer 603 via a wire harness.

[0030] When the conveyor chain plate 206 moves the circular plate 304 between the pusher 503 and the insertion shaft 604, the electric push rod 502 is activated. The electric push rod 502 pushes the pusher 503 to move, and the pusher 503 pushes the circular saw blade and the circular plate 304 to move. The circular plate 304 drives the limiting block 305 and the connecting shaft 302 to slide, so that the connecting shaft 302 is connected to the insertion shaft 604 through the insertion groove 303. At this time, the circular saw blade moves to the bottom of the ultrasonic head 605, and the ultrasonic device 603 and the second motor 602 are activated. The second motor 602 drives the circular plate 304 and the circular saw blade to rotate through the insertion shaft 604. The ultrasonic device 603 and the ultrasonic head 605 perform ultrasonic stress relief on the multiple cutting heads of the circular saw blade one by one.

[0031] In one embodiment, for the circular plate 304, a rotating ring 7 is rotatably connected inside the circular plate 304, a sliding rod 8 is fixedly connected to the outer surface of the rotating ring 7, a limiting plate 9 is fixedly connected to the end of the sliding rod 8, a spring 10 is fixedly connected to the outer surface of the limiting plate 9, the sliding rod 8 and the limiting plate 9 are both slidably connected to the support plate 301, and the end of the spring 10 is fixedly connected inside the support plate 301.

[0032] When the circular plate 304 slides, it pushes the sliding rod 8 and the limiting plate 9 to slide synchronously. The limiting plate 9 compresses the spring 10. When the circular plate 304 rotates, the rotational connection between the circular plate 304 and the rotating ring 7 can prevent the sliding rod 8 from hindering the rotation of the circular plate 304.

[0033] Through the above technical solution: 1. By connecting the support component 3 and the adjustment component 4, after the circular saw blade is placed on the outer surface of the support component 3, the adjustment component 4 inside the support component 3 is moved. The adjustment component 4 simultaneously drives the two sets of support members of the support component 3 to move. The two sets of support members of the support component 3 can move away from or closer to each other, so that the support component 3 can support and fix circular saw blades with different hole diameters. There is no need to replace the support component 3 during use, which is more convenient.

[0034] 2. Through the connection of the connecting shaft 302 and the insertion shaft 604, when the insertion shaft 604 enters the insertion groove 303 on the outer surface of the connecting shaft 302, the insertion shaft 604 can drive the connecting shaft 302 and the circular plate 304 to rotate. The circular plate 304 drives the first support rod 306, the second support rod 307 and the circular saw blade to rotate simultaneously, so that the multiple cutting heads of the circular saw blade approach the ultrasonic head 605 one by one to perform ultrasonic vibration to eliminate stress and improve the stress elimination rate.
