Description

Technical Field

[0001] This utility model relates to the field of annealing technology, and in particular to a bright annealing apparatus for processing stainless seamless steel pipes. Background Technology

[0002] Stainless steel seamless pipes are widely used in various industrial fields such as petroleum, chemical, pharmaceutical, food, and machinery, and are highly favored for their excellent corrosion resistance, high strength, and good plasticity. However, in actual production, the surface quality and mechanical properties of steel pipes are often affected by internal stress, surface oxidation, and other defects generated during processing. To solve these problems, bright annealing technology has emerged. However, existing bright annealing equipment for processing stainless steel seamless pipes still suffers from problems such as the inability to automatically feed and unload the pipes, and the inability to quickly raise the temperature of the steel pipes to a suitable level.

[0003] Therefore, it is essential to invent a bright annealing apparatus for processing stainless seamless steel pipes. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a bright annealing device for processing seamless stainless steel pipes, solving the issues that existing bright annealing devices for seamless stainless steel pipe processing still suffer from the inability to automatically feed and unload materials, and the inability to quickly raise the temperature of the steel pipe to a suitable level. A bright annealing device for processing seamless stainless steel pipes includes a mounting base, a worktable, an input structure, a steel pipe, a high-frequency generator, a high-frequency heating ring, and an output unloading structure. The mounting base is fixedly installed at the bottom of a sealed chamber, and the worktable is fixedly installed at the input end of the mounting base. The input structure is fixedly installed on the surface of the worktable. The steel pipe is placed on the input structure, and the high-frequency generator is fixedly installed on one side of the mounting base. The high-frequency heating ring is fixedly installed on the high-frequency generator. The output unloading structure is fixedly installed at the output end of the mounting base.

[0005] The output feeding structure includes a support platform, an output table, a discharge port, a push rod, a feeding plate, and an output structure. The support platform is fixedly installed at the output end of the mounting base, and both ends of the output table are fixedly installed on the support platform and the worktable. The discharge port is opened inside the output table, and the push rod is fixedly installed on the surface of the mounting base. The feeding plate is fixedly installed on the top of the push rod and located between the discharge ports. The output structure is fixedly installed on the surface of the output table.

[0006] The high-frequency heating ring employs a high-frequency heating structure driven by a high-frequency generator, positioned between the input and output unloading structures. This ring is located along the path of the moving steel pipe. The center point of the high-frequency heating ring is aligned with the centerline of the steel pipe, serving the following functions: ① Heating the steel pipe: The high-frequency heating ring generates an electromagnetic field through high-frequency current, inducing heat and rapidly heating the steel pipe to the required annealing temperature. This heating method provides rapid and uniform heating, avoiding the problems of localized overheating or uneven heating that may occur with traditional heating methods; ② Bright annealing: During the heating process, the steel pipe surface is heated uniformly, eliminating internal stress and resulting in better mechanical properties and surface quality. Bright annealing improves the ductility and toughness of the steel pipe, while also making its surface smoother and more lustrous; ③ High-efficiency production: Due to the high-frequency heating method of the high-frequency heating ring, the required temperature can be reached quickly, and steel pipes can be processed continuously. The entire annealing process is more efficient, suitable for large-scale production, and improves production efficiency and economic benefits.

[0007] The output platform inside the output feeding structure is made of a steel metal plate, and the discharge ports are evenly distributed inside the output platform. The push rod consists of several sets of electric push rods. The feeding plate can move vertically inside the discharge port under the drive of the push rods, and the feeding plate is provided with a ramp, with the inner side of the feeding plate being higher than its outer side. The output structure consists of several sets, and the rear end of the output structure is provided with a motor to drive its movement, which has the following functions: ① Support and stability: The support platform and output platform in the output feeding structure provide stable support, ensuring that the annealed steel pipe remains stable during the conveying and feeding process, and will not affect the quality due to shaking; ② Pushing and feeding: The push rods and the feeding plate work together. Driven by the electric push rods, the steel pipe slides down from the feeding plate for output. The feeding plate can move vertically under the drive of the push rods, and is designed with a ramp to allow the steel pipe to slide out smoothly.

Bright annealing can improve the ductility and toughness of the steel pipe, while making its surface smoother and lusterier; ③ High-efficiency production: Because the high-frequency heating method of the high-frequency heating ring can quickly reach the required temperature and can continuously process steel pipes, the entire annealing process is more efficient, suitable for large-scale production, and improves production efficiency and economic benefits.

[0010] 2. The output feeding structure of this utility model has the following functions: ① Support and stability: The support platform and output platform in the output feeding structure provide stable support, ensuring that the annealed steel pipe remains stable during the conveying and feeding process, and will not be affected by shaking;
