Description

Technical Field

[0001] This invention relates to the field of electroplating technology, and in particular to a traction wheel for diamond wire saws and a manufacturing method thereof. Background Technology

[0002] Diamond wire saws, also known as diamond wire saws, are linear superhard material tools made by electroplating a metal wire with a layer of metal deposited on it and diamond abrasive bonded within the metal. During the electroplating process, a traction wheel is used. The traction wheel contacts the wire, making the wire a negative electrode for conduction, thus depositing nickel plating on the wire surface. During electroplating, the wire only contacts a portion of the conductive rod. Over time, this contact area wears down. Furthermore, in traditional diamond wire saws, the electroplating solution tends to settle during electroplating, affecting the plating effect.

[0003] Chinese utility model patent with announcement number CN218145132U provides a method for manufacturing a traction wheel for a diamond wire saw, including a base shaft, two metal plates, several traction wheel plates, four screws, and several conductive rods.

[0004] Although this patent allows for the replacement of worn parts of the conductive rod, it does not allow for the stirring of the electroplating solution to prevent sedimentation. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention adopts the following technical solution: a traction wheel for manufacturing diamond wire saws, comprising a frame, a conveying mechanism, a traction wheel mechanism, and a take-up mechanism. The frame is equipped with the conveying mechanism, the traction wheel mechanism, and the take-up mechanism. The traction wheel mechanism includes a support plate, a bracket, a drive assembly, a transmission assembly, and a traction wheel assembly. The support plate is fixedly mounted on the bracket, and the drive assembly and the transmission assembly are mounted on the support plate. The transmission assembly is equipped with the traction wheel assembly. The traction wheel assembly includes a traction wheel and a conductive impeller. The traction wheel is provided with a spiral groove, and the spiral grooves of the conductive impeller and the traction wheel form a spiral electroplating groove. The traction wheel and the conductive impeller are coaxially arranged.

[0006] Furthermore, the drive assembly includes a first drive gear, a drive shaft, and a second drive gear. Both the first drive gear and the second drive gear are fixedly mounted on the drive shaft, and the drive shaft is rotatably mounted on the bracket.

[0007] Furthermore, the transmission assembly includes a support unit and a transmission unit, wherein the support unit is disposed on a support plate and the transmission unit is disposed on the support unit.

[0008] Furthermore, the support unit includes a horizontal plate and a bearing seat, wherein the horizontal plate is detachably mounted on the support plate, and the bearing seat is fixedly mounted on the horizontal plate.

[0009] Furthermore, the transmission unit includes a transmission shaft, a transmission gear, a limiting sleeve, and a follower gear. The two ends of the transmission shaft are rotatably mounted on bearing seats. A conductive impeller is fixedly mounted on the transmission shaft. The transmission gear and the drive gear are meshed together. A limiting sleeve is fixedly mounted on the transmission gear. The limiting sleeve is fixedly mounted on a traction wheel. An end cover is fixedly mounted on the first side of the traction wheel. An end cover is detachably mounted on the second side of the traction wheel. The end cover is rotatably mounted on the transmission shaft. A follower gear is fixedly mounted on the transmission shaft. The follower gear and the drive gear are meshed together.

[0010] Furthermore, the take-up mechanism includes a take-up frame, a take-up gear, and a take-up roller.

[0012] A method for manufacturing a wire saw using a traction wheel specifically includes the following steps:

[0013] S1: Pass one end of the wire through the conveying roller, fixed plate, and movable plate, and wind it into the spiral electroplating groove composed of the conductive impeller and traction wheel. Then, pass one end of the wire through the guide roller and fix it on the take-up roller. S2: Drive the conveying roller to rotate through the conveying shaft to convey the metal wire. S3: Make the traction wheel and conductive impeller rotate synchronously through the traction wheel mechanism to stir the electroplating solution and electroplat the wire.
