Description

Technical Field

[0001] This application belongs to the field of precision manufacturing equipment technology for diamond wire, and specifically relates to a diamond wire drawing device that integrates dynamic tension compensation and online self-cleaning functions and can self-lubricate and clean itself. Background Technology

[0002] Diamond wire core is a core material used in the production of electroplated diamond wire and resin-coated diamond wire, produced using high-quality raw materials, advanced heat treatment processes, and wire drawing techniques. It features high strength, precise dimensions, and excellent surface cleanliness. The wire drawing process is primarily carried out using a wire drawing machine. This machine works by unwinding the wire from a coil and winding one end onto a take-up reel. As the wire is unwound and retracted, it passes through a drawing die, causing the wire to thin from thick to thin, thus increasing its length.

[0003] In CN118321361A, a self-lubricating wire drawing device for diamond wire busbars with rapid wire drawing and take-up is disclosed. However, it only uses a torsion spring buffer mechanism to achieve passive tension adjustment, which cannot simultaneously complete the lubrication and cleaning functions. Moreover, the buffer wheel has an open structure, in which diamond powder easily accumulates, causing fluctuations in wire diameter. Once the wire diameter fluctuates, it is prone to breakage. Therefore, this disclosure does not effectively solve the problem of wire breakage caused by tension fluctuations during high-speed wire drawing in existing technologies. In addition, traditional lubrication requires an external oil supply system, resulting in high overall oil consumption. Utility Model Content

[0004] The purpose of this invention is to address existing problems by providing a self-lubricating and cleaning diamond wire drawing device.

[0005] To achieve the above technical objectives, the following technical solution is provided: a self-lubricating and cleaning diamond wire drawing device, comprising a main body, an output drum fixed on one side of the main body, and a take-up drum on the other side; a wire drawing mechanism is provided on the main body between the output drum and the take-up drum.

[0006] The feature is that a self-lubricating cleaning mechanism is provided between the wire drawing mechanism and the take-up drum. The self-lubricating cleaning mechanism includes a base plate fixed to the main body of the equipment and serving as a support base for the take-up drum. The front of the base plate has a vertically arranged guide rail. A horizontal groove is opened on the base plate below the guide rail to accommodate a pair of self-lubricating claws. The self-lubricating claws are connected to damping claws fixed to the back of the base plate. A support rod is fixed to the base plate below the horizontal groove. A pair of winding wheels are provided on the support rod. An adjusting slider is provided on the guide rail.

[0007] After the diamond wire flows out from the drawing mechanism, it enters a winding wheel on one side, then moves upward into a self-lubricating chuck on one side, and continues upward into an adjusting slider. It then flows out from the adjusting slider and moves downward into another self-lubricating chuck on the other side, and enters another winding wheel on the other side. Finally, it enters a deflector wheel fixed to the upper part of the base plate and then enters the take-up drum.

[0008] In one feasible embodiment, the adjusting slider includes a base block that mates with a guide rail, a cover plate located in front of the base block, a top support integrally formed with the base block between the cover plate and the base block, and a pair of adjusting wheels at the bottom to assist in the steering of the diamond wire.

[0009] In one feasible embodiment, the wire drawing mechanism includes a pair of tapered rollers disposed on both sides of the main body of the equipment, and a plurality of diamond wire tracks are provided on the tapered rollers, the diameter of which gradually increases in the direction away from the main body of the equipment.

[0010] In one feasible embodiment, the wire drawing mechanism further includes a wire drawing component located between a pair of conical rollers. The wire drawing component includes a wire drawing bracket fixed to the main body of the equipment. The wire drawing bracket has a wire drawing groove aligned with the diamond wire track. The wire drawing bracket also has at least two slots perpendicular to the wire drawing grooves. Each slot contains a wire drawing cylinder that mates with each diamond wire track.

[0011] In one feasible approach, the main body of the equipment is provided with a mounting groove, which contains several wire drawing cylinders.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] The diamond wire of this application has a consistent diameter throughout the diamond wire track, and the diameter remains consistent after drawing; this effectively controls the breakage rate. The adjusting slider integrates elastic preload and hydraulic damping dual-mode adjustment, allowing for adjustment of the diamond wire tension. Furthermore, the self-lubricating jaws can adjust the diamond wire tension at any time during the drawing process. Additionally, the cleaning components on the self-lubricating jaws allow for the removal of powder and debris from the diamond wire; the jaws can be replaced only when there is excessive debris, making disassembly and assembly convenient.

[0014] Specifically designed for high-speed wire drawing (wire speed ≥ 15m / s) of diamond wire used in photovoltaic silicon wafer cutting, this product achieves triple optimization of tension stability, lubrication continuity, and cleaning efficiency through the synergistic design of an innovative self-lubricating cleaning mechanism and a multi-stage tension adjustment system.
