Description

Technical Field

[0001] This invention relates to the field of heat treatment equipment technology, specifically to a device for regulating the temperature uniformity of a stainless steel annealing furnace. Background Technology

[0002] Annealing is a core heat treatment process for stainless steel pipe fittings. It is primarily used to eliminate residual stress generated during cold drawing, bending, stamping, and other forming processes, optimize the internal metallographic structure, and ensure that the mechanical properties of the pipe fittings meet stable standards. After forming and before leaving the factory, stainless steel pipe fittings require annealing to improve product quality and eliminate processing defects.

[0003] Traditional annealing of stainless steel pipe fittings involves static heating, fixed-space conveying, passive hot air diffusion, and fixed-distance installation of heating components. However, static heating suffers from uneven heating of the pipe fittings, localized overheating and underheating, and significant temperature differences between the core and surface. Fixed-space conveying cannot adapt to pipe fittings of different lengths and specifications, resulting in poor production adaptability. Passive hot air diffusion leads to a chaotic thermal field within the furnace, uneven heat diffusion, and inconsistent annealing quality. Fixed-distance installation of heating components restricts the flexibility of heating distance adjustment and results in low heat utilization. Furthermore, traditional equipment lacks buffer and protective structures, making the conveying mechanism prone to collisions and damage to the furnace body. Poor furnace sealing leads to significant heat loss, further exacerbating the temperature imbalance problem.

[0004] Based on this, the present invention provides a device for adjusting the temperature uniformity of stainless steel annealing furnace to solve the above-mentioned technical problems. Summary of the Invention

[0039] Please see Figure 9 , Figure 12 and Figure 13 The first support frame 61 provides support for the installation of the fourth drive shaft 619.

The third rectangular block 624 provides support and limiting for the third motor 621, so that the third motor 621 can generate driving force well. The fourth bevel gear 622 is used to transmit the driving force of the third motor 621 to the second drive shaft 613. Detailed implementation method: When using this invention to anneal stainless steel pipe fittings, during transportation, the distance between the first support frame 61 and the second support frame 62 is adjusted according to the required length of the stainless steel pipe fitting to be annealed. To adjust the distance, simply tighten the two nuts 67 on the threaded rods 68 on both sides. Then, the fifth slide rod 64 allows the first support frame 61 and the second support frame 62 to slide and adjust the distance. When the distance is adjusted to a suitable length for the stainless steel pipe fitting, tighten the nuts 67 on the threaded rods 68. The first rectangular block 66 then supports the first support frame 61 and the second support frame 62. With roller 62 fixed at its limit, the stainless steel tube to be annealed is placed between the outer sides of the two rollers 63. After placement, the third motor 621 in the rotary conveyor mechanism 6 is started. When the third motor 621 starts, the fourth bevel gear 622 will transmit the driving force of the third motor 621 to the first bevel gear 614, and then to the outer side of the second drive shaft 613. After the second drive shaft 613 rotates, the rotary conveyor mechanism 6 will move towards the second frame 12 on the slide rail 20. During the movement, the second bevel gear 615 is driven by the driving force. The driving force is transmitted to the second gear 611 via the third bevel gear 620, the third gear 616, and the fourth gear 617. Subsequently, the roller 63 rotates, which in turn drives the stainless steel pipe to rotate, ensuring uniform heating during annealing. Due to the inherent limiting mechanisms between the gears, the first support frame 61 and the second support frame 62 will not move significantly due to small external forces. As the pipe is conveyed into the second frame 12 and heated by the second resistance wire 36 and the first resistance wire 29, the third motor 621 can be continuously activated. The first support frame 61 and the second support frame 62 move back and forth slightly. Due to the roller 63, the angle at which the roller 63 drives the stainless steel pipe to rotate is not fixed. Therefore, the stainless steel pipe can be heated evenly through multiple rotations. The second circular plate 30, the second spring 31, the second circular block 32, and the fourth slide rod 33 set on the second frame 12 and the first circular plate 3, the first spring 4, and the first slide rod 5 set on the second rectangular plate 2 can prevent the first support frame 61 and the second support frame 62 from colliding and causing damage to the furnace when they move significantly.

[0041] During the heating process, the hydraulic devices 15 installed on both sides of the second frame 12 can be activated. The hydraulic devices 15 will push and pull the second furnace lining 35, so that the second resistance wire 36 installed on the second furnace lining 35 can be close to or away from the stainless steel pipe as needed, thereby improving the heating effect.

[0042] The first frame 11, second motor 23, and fan blades 34 installed on the second frame 12 can realize the internal circulation of hot air. Simply start the second motor 23 to drive the fan blades 34 to rotate. The fan blades 34 will transport the hot air inside the second frame 12 to the first frame 11 through the second circular hole 26 and the third circular hole 27, and blow it from the top of the second frame 12 into the second frame 12 through the first circular hole 25 opened at the top of the second frame 12. Since the top of the inner side of the second frame 12 does not have a heating function, the uniform heating effect of the stove can be improved.

[0043] During heating, the first motor 16 is started, and the first gear 19 at the output end of the first motor 16 transmits the driving force of the first motor 16 to the first gear rack 10. The circular slider 21 that slides with the third slider 22 achieves the sealing effect of the third rectangular plate 9 on the second frame 12, thereby improving the heating effect.
