Description

Technical Field

[0001] The invention belongs to the technical field of metal wire drawing annealing, in particular to a wire drawing annealing device for precious metal processing. Background Art

[0002] In the field of precious metal processing, wire drawing annealing is a key process link that directly affects the quality and performance of precious metal wires. Traditional precious metal wire drawing annealing equipment has many problems in actual production and can no longer meet the production needs of modern industry for high-quality precious metal wires.

[0003] Existing eyelet die trays are usually tilted, and when workers are threading and placing eyelet dies, the eyelet dies are very likely to roll off directly, which not only increases the time cost for workers to pick up the dies, but also frequently interrupts the operation and seriously affects the overall processing efficiency; moreover, when replacing wire drawing rollers of different specifications, it is difficult for existing equipment to effectively adapt to the new wire drawing rollers, resulting in a significant reduction in wire drawing accuracy and stability; in addition, during the wire drawing process and steam antioxidant treatment, a large amount of lubricants, metal debris and other impurities will remain on the wire. During the later cooling process of the wire, these impurities will cause the surface quality of the wire to deteriorate, and even cause serious defects such as oxidation and cracks, which will directly affect the quality and performance of the finished precious metal wire and make it difficult to meet the strict requirements of high-end precious metal products on material quality; after the existing equipment is completed, due to the thin diameter and high value of the precious metal wire, the fine wear generated during the wire drawing process cannot be observed with the naked eye, but these fine wear will affect the mechanical properties and quality of the wire. If unqualified products are not detected in time and flow into subsequent processing links, it will cause greater economic losses. Summary of the Invention

[0048] The method for using a wire drawing annealing device for precious metal processing described in this embodiment includes the following steps:

[0049] In step one, the worker passes the precious metal wire (i.e. wire rod) to be processed through the eyelet die on the eyelet die disc 3, and provides traction power through the rotating wire pulling roller 2; the eyelet die disc 3 can adjust the angle through the transmission of the worm gear 10 and the worm 11 to ensure that the threading process is stable and the die is not easy to roll off.

[0050] In step 2, before the wire enters the annealing stage, it is first surface cleaned by the cleaning assembly. The ion wind generators 63 on both sides of the cleaning box 13 work continuously to generate ion wind to eliminate static electricity on the wire and prevent static electricity from adsorbing impurities. In the initial state, one cleaning brush plate 16 cleans the wire; when the brush plate is used for a long time, the other cleaning brush plate 16 automatically switches to the working position, and the dirty cleaning brush plate 16 is retracted into the storage slot 23. The cleaned wire passes through the detection drum 57 in the U-shaped bracket 56 installed on the workbench 1. The third motor 66 drives the driving gear 65 and the driven gear ring 64 to rotate, so that the detection drum 57 rotates continuously, and the detection ball 61 contacts the surface of the wire. The pressure sensor 62 monitors the pressure change in real time. If there is slight wear on the wire, the pressure change signal will be fed back to the control system. In addition, the partition 18 moves back under the drive of the third electric push rod 19 on the top. After moving to the end in the sliding slot, it touches the first contact point, triggering the first pump 20 to spray and clean the brush plate to ensure continuous and efficient cleaning effect.

[0051] In step three, the cleaned wire is annealed and treated with antioxidants by passing through the heating box 5 and the steam cabinet 4 in turn; the heating wire coil 6 and the steam pipe 33 provide a controllable high temperature environment and steam atmosphere respectively, and the second heating wire 29 maintains the annealing temperature to ensure that the wire structure is uniform.

[0052] In step 4, the annealed wire enters the cooling assembly through the second connecting pipe 8, and the third wire pressing roller 36 in the water tank 35 guides the wire to be sprayed with circulating cooling water for cooling; then, the wire passes through the outlet rectangular opening 51, and is dried by the second fan 37 and the third heating wire 52, and the second water absorption block 53 further removes residual moisture.

[0053] In step five, the dried wire is guided by the second wire reel 46 to the take-up roller 50; the slider 45 reciprocates under the drive of the screw 43. When the second contact point 47 touches the contact disc 48, the screw 43 reverses to cause the slider 45 to move in the opposite direction, achieving uniform wire arrangement; by adjusting the position of the contact disc 48, the reciprocating spacing can be changed to adapt to different take-up requirements.
