Description

Technical Field

[0001] The invention relates to the field of tungsten-molybdenum wire grinding equipment, in particular to tungsten-molybdenum post-processing grinding equipment. Background Art

[0002] Tungsten-molybdenum electrodes are usually used in the welding process of precision instruments. The tungsten-molybdenum electrodes are produced by sintering tungsten-molybdenum rods and then drawing them into wires. The formed tungsten-molybdenum wires are then surface-polished by special grinding equipment.

[0003] The existing patent (publication number: CN219005660U) discloses a wire polishing device, including a workbench, on which two guide wheels are installed. In the process of implementing the solution, the inventor found that the following problems in the prior art have not been well solved: 1. During the use of some existing tungsten-molybdenum wire polishing equipment, the surface of the tungsten-molybdenum wire is polished only by rotating two polishing rollers. This state can only polish the tungsten-molybdenum wire conveyed at a low speed. When the conveying speed of the tungsten-molybdenum wire is increased, the two polishing rollers are in a two-point contact mode, which easily causes the situation of missing polishing, and the work efficiency is low.

When the tungsten-molybdenum wire is transmitted from the position of the left feeding cylinder 5, the tungsten-molybdenum wire enters the main slider 7 and the support ring 1001 at the top of the slave slider 8 for grinding.

[0064] Specifically, when the conveying motor 901 on the feeding barrel 5 rotates with the conveying rod 902, the conveying rod 902 rotates with the turntable 903, so that the transmission pin 904 on the turntable 903 cooperates with the transmission groove 906 in the middle of the transmission bar 905 to slide. At this time, the transmission bar 905 carries the L-shaped pull rod 907 and the main slider 7 to slide back and forth on the surface of the slide bar 6. When the main slider 7 slides to the left, the main slider 7 cooperates with the guide wheel 910 to slide the slave slider 8 to the right through the pull rope 908. When the main slider 7 slides to the right, the compression spring 911 drives the slave slider 8 to slide to the left on the surface of the slide bar 6, so that the main slider 7 and the support ring 1001 on the slave slider 8 can move relative to and away from each other;

[0065] At the same time, during the translation of the main slider 7 and the slave slider 8 with the corresponding support ring 1001, the circular gear 1006 at the side wall position of the main slider 7 and the slave slider 8 is meshed with the rack 1007 between the two support blocks 4, so that the circular gear 1006 and the bevel gear rod 1005 are meshed with the corresponding bevel gear ring 1003. At this time, the bevel gear ring 1003 rotates inside the support ring 1001 with the adjusting ring 1002, so that the three grinding rollers 1011 inside the adjusting ring 1002 are polished as they rotate. Since the grinding roller 1011 rotates to polish the tungsten-molybdenum wire and performs a horizontal reciprocating translation at the same time, it can effectively avoid the occurrence of missed grinding.

[0066] At the same time, during the lateral reciprocating movement of the support ring 1001, the synchronous gear plate 1017 on the top of the support ring 1001 meshes with the transmission gear rod 1105 on the same side, so that the transmission gear rod 1105 rotates with the eccentric disk 1102. Under the action of the eccentric setting of the transmission shaft in the middle of the eccentric disk 1102, the rotating eccentric disk 1102 reciprocates inside the water pump 1101 through the hinged rod 1103 with the piston disk 1104, so that the water at the bottom of the support frame 1 is transported from the water suction pipe 1106 to the spring water pipe 1107 and the nozzle 1108 and sprayed out, so as to reduce dust on the tungsten-molybdenum wire during the grinding process, avoid the need to set up a separate circulating sprinkler, and effectively save costs;

[0067] When the spacing between three adjacent grinding rollers 1011 needs to be adjusted, the movable ring 1012 is pressed to release the arc-shaped tooth plate 1015 on the movable ring 1012 from the corresponding tooth block 1016, and then the movable ring 1012 is rotated to make the arc-shaped groove 1013 on the movable ring 1012 slide in cooperation with the sliding pin 1009. At this time, the sliding pin 1009 translates along the trajectory of the sliding groove 1008, so that the sliding pin 1009 moves with the connecting plate 1010 and the grinding roller 1011 to adjust the position, and then after the movable ring 1012 is released, the spring rod 1014 presses the movable ring 1012 to move toward the tooth block 1016. When the movable ring 1012 fits against the side wall of the tooth block 1016, the arc-shaped tooth plate 1015 on the movable ring 1012 again engages with the tooth position of the tooth block 1016 to limit the position, which is convenient to operate.
