Description

Technical Field

[0001] This utility model relates to the field of special steel nail processing technology, and in particular to a special steel nail hardening heat treatment equipment. Background Technology

[0002] Special steel nails are made of special steel and processed using specific techniques to achieve special properties and applications. Compared to ordinary steel nails, special steel nails are typically made of high-strength, high-toughness, wear-resistant, and corrosion-resistant alloy steel or stainless steel. In terms of processing, they undergo precision forging, heat treatment, and surface treatment to ensure that the dimensional accuracy, hardness, toughness, and other indicators meet specific requirements. Special steel nails possess a variety of special properties; some have extremely high strength and hardness, capable of withstanding significant impact and tensile forces, making them suitable for fixing in hard materials; others have excellent corrosion resistance, allowing them to be used in humid or corrosive environments without easily rusting; still others have special shapes or structural designs to meet specific construction or installation needs. They are widely used in construction, bridges, machinery manufacturing, the automotive industry, aerospace, and many other fields for connecting and fixing various components or parts.

[0003] When processing special steel nails, heat treatment is often required to improve their hardness. For special steel nails of different specifications and shapes, special areas need to be heated to improve their hardness. However, the heating elements of existing equipment are mostly fixed and cannot be adjusted according to different needs. Therefore, different types of heating furnaces are required for heat treatment, which increases the equipment purchase cost and reduces the production speed.

[0004] Therefore, we propose a special steel nail hardening heat treatment equipment to solve the above problems. Utility Model Content

[0023] In this embodiment, a sealing door 2 is rotatably installed on one side of the heating furnace 1 to improve the heat preservation effect of the heating furnace 1.

[0024] In this embodiment, multiple shelf panels 7 are detachably installed on the inner side of the shelf 6. Multiple limiting holes are opened on the top of each shelf panel 7. The multiple limiting holes are used to place special steel nails, which can make the special steel nails heat evenly.

[0025] In this embodiment, four heating ports are provided on one side of the heating chamber 5, and electric heating plates 8 are fixedly installed on the inner side of each of the four heating ports. Multiple temperature sensors 9 are fixedly installed on the inner top wall of the heating chamber 5 to facilitate monitoring of the temperature inside the heating chamber 5.

[0026] In this embodiment, two sliding grooves are provided on the bottom inner wall of the heating chamber 5. Limiting metal blocks 10 are slidably installed on the inner side of the two sliding grooves. Supporting springs 11 are fixedly installed at the bottom of the two limiting metal blocks 10. The bottom ends of the four supporting springs 11 are fixedly connected to the bottom inner wall of the corresponding sliding groove, so that the corresponding limiting metal blocks 10 can be reset by the four supporting springs 11.

[0027] In this embodiment, the adjustment mechanism includes a temperature control frame 12, four electric heating rods 13, a threaded sleeve 3, an internal gear 4, and a drive assembly. The temperature control frame 12 is slidably fitted on the outer side of the heating chamber 5. Four temperature control ports are opened on one side of the temperature control frame 12. Electric heating rods 13 are fixedly installed on the inner side of each of the four temperature control ports. An internal gear 4 is rotatably installed on the inner wall of one side of the heating furnace 1. A threaded sleeve 3 is fixedly installed on one side of the internal gear 4. A threaded groove is opened on the outer side of the temperature control frame 12. The threaded groove is threadedly connected to the threaded sleeve 3. A drive assembly is provided on the top of the heating chamber 5.

[0028] In this embodiment, the drive assembly includes a heat insulation shell 14, a servo motor 15, and a drive gear 16. The heat insulation shell 14 is fixedly installed on the top of the heating chamber 5. The servo motor 15 is fixedly installed on the inner side of the heat insulation shell 14. The drive gear 16 is rotatably installed on one side of the heat insulation shell 14. The output shaft of the servo motor 15 is fixedly connected to the drive gear 16, so that the drive gear 16 can be rotated by the servo motor 15.

[0029] In this embodiment, the drive gear 16 meshes with the internal gear 4, and the threaded sleeve 3 can be rotated by the drive gear 16.

[0030] Working principle: During the heat treatment of special steel nails, the worker places the steel nails into the limiting holes on the shelf 7, then installs multiple shelves 7 on the shelf 6. The worker then pushes the shelf 6 into the heating chamber 5, where it presses against two limiting metal blocks 10. Under this pressure, the two limiting metal blocks 10 move downwards, and the shelf 6 slides into the heating chamber 5 away from the two limiting metal blocks 10. The two limiting metal blocks 10 then return to their original position under the influence of the rebound force of the corresponding two support springs 11, thus limiting the shelf 6 and preventing it from moving during the heat treatment process. The worker then closes the sealing door 2 and activates the four electric heating plates 8 to heat the heating chamber 5. When specific... When heating a region or when the heat in the heating chamber 5 is uneven, the operator adjusts the temperature inside the chamber by transmitting data from multiple temperature sensors 9 to the control panel. The servo motor 15 is then started, which drives the drive gear 16 to rotate. The drive gear 16 rotates, which in turn drives the internal gear 4 to rotate. The internal gear 4 rotates, which in turn drives the threaded sleeve 3 to rotate. The temperature control frame 12, which is slidably fitted on the outside of the heating chamber 5, has a threaded groove on its outer side. The threaded groove is adapted to the threaded sleeve 3. The rotation of the threaded sleeve 3 drives the temperature control frame 12, which is threadedly connected to it, to move axially. The movement of the temperature control frame 12 drives the four electric heating rods 13 to move, thereby ensuring that the heat inside the heating chamber is uniform or that a specific area is heated.

[0031] The technological advancements of this invention compared to existing technologies are as follows: the position of the heating element can be adjusted, thereby enabling the heating furnace 1 to be adapted to special steel nails of different types and sizes, eliminating the need for frequent replacement of the heating furnace 1 for heat treatment, greatly improving work efficiency while reducing equipment purchase costs, and the placement rack 6 ensures that the special steel nails are heated more evenly.
