Description

Technical Field

[0031] Working principle: When using the diffusion welding device, first start the second motor 8, and the second motor 8 drives the active worm 10 to rotate through the transmission rod 1 9, thereby driving the driven worm wheel 11 and the transmission rod 2 12 to rotate. This series of transmissions changes the angle between the support rod 14 and the vertical line, thereby driving the connecting rod 15 to move along an arc, and at the same time, the electric push rod 16 hinged on the support rod 14 is started, and its output end pushes the connecting rod 15, thereby pushing the connecting rod 15 and the clamping assembly 17 on the connecting rod 15 forward, and then the third motor 18 is started, and the third motor 18 drives the active threaded rod 19 to rotate. Since the threads at both ends of the active threaded rod 19 are opposite, the active threaded rod 19 drives the follower threaded blocks 20 at both ends through the limit slide The grooves 1 21 are close to each other, thereby driving the two groups of clamping plates 22 to clamp the material to be welded, and then the first motor 2 is started to drive the active bevel gear 3 to rotate, and the support seat 6 and the welded material are rotated through the driven bevel gear 4 and the rotating shaft 5 until the end of the material to be welded is located on the second graphite block 35, and then the fourth motor 26 is started, and the fourth motor 26 drives the active bevel gear 28 to rotate through the transmission rod 3 27, and then drives the driven bevel gear 29 and the follower threaded rod 30 to rotate, so that the follower threaded plate 31 drives the clamping plate 22 to move vertically downward along the direction of the limiting slide groove 2 32 until the first graphite block 33 squeezes the material to complete the clamping and positioning of the material, and then the first graphite block 33 is heated by resistance heating. The heat generated by the resistance wire is evenly transferred to the welding material through the heat conduction medium such as graphite, and the graphite, as an electrode material, participates in the transmission of current and the conversion of energy. In addition, the graphite also plays a protective role to prevent the welding material from oxidation reaction at high temperature. After the welding is completed, the first graphite block 33 is lifted by the transmission of the fourth motor 26 to release the welding piece, and then the first motor 2 is started to drive the material to rotate again, and then the second motor 8 is started to put the welding piece into the water through a series of transmissions. The device is cooled during operation to prevent the weld from deforming or causing other thermal effects. The universal wheels 39 under the base 1 make the device highly mobile and flexible, and the staff can easily push the device to the specified position. When the device needs to be fixed at a certain position, the support threaded rod 36 is driven to rotate by turning the knob 37, so that the support foot 38 below moves downward along the thread direction until the support foot 38 is against the ground, thereby stably supporting the entire device and increasing the stability and safety of the equipment. The diffusion welding device achieves uniform heating of the weldment and an efficient and stable welding process through highly automated mechanical transmission, motor drive, resistance heating and the thermal conductivity and protection characteristics of graphite, while improving the welding quality and production efficiency.
