[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1-9An embodiment of the present invention provides a production process for a large-diameter heavy oil quenched straight wire, including a quenching tank 100, a base frame 110 supporting the bottom of the quenching tank 100, a side frame 120 integrally provided on the right side of the base frame 110, a top plate 130 supporting the front and rear sides of the top of the quenching tank 100, and a power distribution control cabinet 150 supported by a front support 140 on the front side of the quenching tank 100.

[0043] It also includes the following process steps:

[0044] S1: Wire processing; Surface treatment of wire rod to remove rust, oil and other impurities. Mechanical rust removal and chemical pickling are used to make the wire surface clean and avoid impurities from affecting the quenching effect and the quality of straight wire.

[0045] S2: Wire feeding; The cleaned wire rod is assembled on the wire feeding frame, and the wire feeding frame is driven to rotate to feed the wire rod smoothly and continuously into the next process stage, avoiding wire tangling, wire breakage and other situations.

[0046] S3: Wire heating; By adjusting the heavy oil burner, heat that meets the process requirements is provided to heat the heating furnace to a suitable temperature to heat the wire.

[0047] S4: Wire quenching; The heated wire is guided into the quenching tank 100 for quenching; The moving speed and time of the wire in the quenching tank 100 are maintained so that the wire is rapidly cooled to below the martensitic transformation temperature, thereby improving the strength and hardness of the wire.

[0048] S5: Auxiliary annealing; after quenching, the wire is annealed in an annealing furnace based on its residual heat or by additional heating.

[0049] S6: Straight wire treatment; straightening of quenched and annealed wire, followed by cutting to a fixed length as needed;

[0050] S7: Quality Inspection; the cut straight wires undergo visual inspection, dimensional inspection, and mechanical property testing.

[0051] S8: Packaging and Warehousing; After passing the inspection, the straight wire products are packaged and stored for subsequent sales and delivery.

[0052] As described in more detail in this embodiment, the quenching tank 100 is vertically supported by an internal stirring structure 200, which includes a stirring shaft 210. The upper part of the stirring shaft 210 is inserted and assembled inside the top plate 130. A stirring blade 220 is sleeved and assembled on the surface of the stirring shaft 210. A bearing sleeve 230 is assembled on the upper part of the stirring shaft 210, and two sets of bearing sleeves 230 are supported on the upper and lower surfaces of the top plate 130. A lower support sleeve 240 is supported at the bottom of the stirring shaft 210.

[0053] Therefore, during assembly and use, it is convenient to provide stable support for the stirring shaft 210 and the stirring blade 220, making it easier and more efficient for the subsequent transmission rotation to stir the quenching medium inside the quenching tank 100, and making it easier to ensure relatively uniform internal temperature.

[0054] As described in more detail in this embodiment, the discharge end on the right side of the quenching tank 100 is supported by a traction assembly 300 via a side frame 120, and the traction assembly 300 includes an upper traction roller 310 and a lower traction roller 320.

[0055] The upper traction roller 310 and the lower traction roller 320 are supported by bearing brackets 330 on both sides, and the bearing brackets 330 are supported on the top of the side frame 120. The front ends of the upper traction roller 310 and the lower traction roller 320 are respectively equipped with meshing upper gear 340 and lower gear 341. The lower gear 341 is meshed with a drive gear 342 below it, and a drive shaft 343 is fixed inside the drive gear 342. The drive shaft 343 is installed on the front end of the bearing bracket 330 through bearing insertion, and the front end of the drive shaft 343 is fixedly connected to the driven wheel 442. The front and rear sides of the drive shaft 343 are supported by bearing shaft brackets 344, and the bearing shaft brackets 344 are supported on the surface of the side frame 120.

[0056] This facilitates stable support and transmission of the upper traction roller 310 and the lower traction roller 320, and facilitates the traction operation and subsequent processing of the quenched wire.

[0057] Both the upper traction roller 310 and the lower traction roller 320 are respectively provided with an inner traction groove 311 in the center, and the inner side of the surface of the inner traction groove 311 is arc-shaped.

[0058] Therefore, during assembly and use, the wire is easily clamped and pulled by the inner traction groove 311, making the operation and pulling more convenient and easy to maintain a stable clamping and pulling transmission. Under the limitation of the arc groove, the wire is less likely to be disordered during discharge.

[0059] As described in more detail in this embodiment, the front support 140 surface is supported and equipped with a drive structure 400 for driving the internal stirring structure 200 and the traction assembly 300. The drive structure 400 includes a servo structure 410 that is electrically connected to the power distribution control cabinet 150.

[0060] The output end of the servo structure 410 is equipped with a reducer 411, and the output end of the reducer 411 is connected to a drive shaft 420 through a coupling. A worm 430 is installed in the middle of the drive shaft 420, and a worm wheel 431 meshes with the side of the worm 430. A driven shaft 432 is fixed inside the worm wheel 431. A drive wheel 440 is fixed at the front end of the driven shaft 432, and a driven wheel 442 is sleeved and connected to the side of the drive wheel 440 through a belt 441.

[0061] Therefore, during assembly and use, it is convenient to synchronously drive the drive shaft 420, worm 430 and drive wheel 440, making operation and use more convenient. Furthermore, under the meshing transmission of worm 430 and worm wheel 431, the transmission speed of drive wheel 440 is slower than that of drive shaft 420, which facilitates the rapid rotation and stirring of internal stirring structure 200 and the slow rotation and traction of traction component 300, making operation and use more convenient.

[0062] A drive sprocket 450 is fixed at the top of the drive shaft 420. Four sets of stirring shafts 210 are arranged in a rectangular shape inside the quenching tank 100. Each of the four sets of stirring shafts 210 has a driven sprocket 451 fixed at the top, corresponding to the drive sprocket 450. The drive sprocket 450 and the driven sprocket 451 are connected and driven by a drive chain 452.

[0063] This facilitates stable transmission of the stirring shaft 210, enabling stable transmission and rotation of the surrounding servo structure 410 and transmission shaft 420, making operation more convenient and efficient.

[0064] The worm gear 430 is provided with seated bearings 421 at both the top and bottom. The seated bearings 421 are sleeved and supported on the outside of the drive shaft 420 and supported on the front outer wall of the quenching tank 100. The top of the drive shaft 420 is supported by an upper bearing sleeve 422, which is supported on the front side of the top plate 130. The rear end of the driven shaft 432 is supported by a rear bearing support 433, which is supported on the front wall surface of the quenching tank 100.

[0065] Therefore, during assembly and use, it is convenient to stably support the drive shaft 420 and driven shaft 432, making the assembly and transmission more stable and convenient.

[0066] As described in more detail in this embodiment, a guide component 500 is assembled on the upper left side of the quenching tank 100, and an auxiliary component 600 is longitudinally assembled inside the quenching tank 100.

[0067] The guiding assembly 500 includes an upper guide roller 510 and a lower guide roller 520 arranged parallel to each other. An upper roller shaft 511 and a lower roller shaft 521 are installed inside the upper guide roller 510 and the lower guide roller 520 through bearings. The upper roller shaft 511 and the lower roller shaft 521 are installed on the top left side wall of the quenching tank 100 and fastened with nuts. A partition plate 530 is sleeved on the outer wall of the upper guide roller 510 and the lower guide roller 520. An upper stud 540 and a lower stud 550 are inserted through the partition plate 530 at both the top and bottom. The upper stud 540 and the lower stud 550 are supported on the inner side wall of the top left side of the quenching tank 100. A limiting nut 560 is threaded on the outer wall of the upper stud 540. Two sets of limiting nuts 560 are distributed on both sides of the partition plate 530. The two sets of partition plates 530 are normally set as one set.

[0068] Therefore, when the wire is in the quenching tank 100, it is convenient to limit and hold it by two sets of partition plates 530. At the same time, with the cooperation of the upper guide roller 510 and the lower guide roller 520, it is convenient to guide the wire, making the operation more convenient and efficient. It is also convenient to use auxiliary partitioning to guide multiple strands of wire into the quenching tank.

[0069] The auxiliary component 600 includes a left inner shaft 610, a middle inner shaft 620, and a right inner shaft 630 arranged in parallel. The left inner shaft 610 and the right inner shaft 630 are symmetrically arranged on both sides of the middle inner shaft 620, and the left inner shaft 610 and the right inner shaft 630 are synchronously higher than the middle inner shaft 620. The surfaces of the left inner shaft 610, the middle inner shaft 620, and the right inner shaft 630 are all fitted with auxiliary rollers 640 through bearings, and the outer wall of the auxiliary rollers 640 is arranged with an arc-shaped concave side.

[0070] Therefore, during assembly and use, when the wire is inserted into the quenching medium inside the quenching tank 100, the left inner shaft 610, the middle inner shaft 620 and the right inner shaft 630, as well as the limiting guidance of the auxiliary roller 640, make the immersion quenching operation of the wire more convenient and efficient.

[0071] Working principle: During operation, the wire is first pre-treated by mechanical rust removal and chemical pickling; then, the wire is unwound with the help of a wire unwinding rack and other devices; further, the heating furnace is heated with the help of a heavy oil burner so that the wire can undergo heat treatment after entering; next, the wire is quenched in the quenching tank 100, and the internal speed is ensured during quenching so that the wire can be cooled quickly to below the martensitic transformation temperature, which is beneficial to improve strength and hardness. Then, it is tempered in the tempering furnace as needed, and the tempering operation is selected according to its own temperature or supplementary heating. Finally, the quenched and tempered wire is straightened and cut, and after passing inspection, it is packaged and delivered according to customer requirements.

[0072] During operation, the servo structure 410 is controlled by the power distribution control cabinet 150. With the cooperation of the transmission shaft 420 and the worm gear 430, the drive gear 342 and the drive shaft 343 are driven to rotate through the worm wheel 431 and the driven shaft 432, and with the cooperation of the transmission wheel 440, the belt 441 and the driven wheel 442. This, in turn, drives the upper traction roller 310 and the lower traction roller 320 to rotate synchronously in opposite directions, which facilitates the traction and discharge of the wire after quenching. At the same time, with the cooperation of the transmission shaft 420, the transmission sprocket 450, the driven sprocket 451 and the transmission chain 452, the stirring shaft 210 is driven to rotate synchronously. This causes the stirring shaft 210 to drive the stirring blades 220 to stir the quenching medium inside the quenching tank 100, which helps to maintain the temperature balance of the quenching medium and is beneficial to the stable quenching of the wire.

[0073] During operation, the upper guide roller 510 and the lower guide roller 520 work together to facilitate the entry and exit of the wire. Then, under the limitation of the partition plate 530, the upper stud 540 and the lower stud 550 maintain the sliding support and the limit nut 560 limit the adjustment support, so that the two sets of partition plates 530 can easily maintain the limit blocking support, thereby facilitating the separation of multiple strands of wire when entering the quenching process, making the operation more convenient. At the same time, with the sequential auxiliary support of the left inner shaft 610, the middle inner shaft 620 and the right inner shaft 630, the correspondingly assembled auxiliary rollers 640 facilitate the effective immersion of the wire to be quenched into the quenching medium, which is conducive to stable quenching operation.
