Description

Technical Field

[0001] This utility model relates to the field of bar processing technology, specifically to a heat treatment fixture for metal bars. Background Technology

[0002] Metal bars are solid, long strip-shaped metal materials made through processes such as hot rolling, forging, extrusion, or drawing. They are widely used in machinery manufacturing, construction, energy, electronics, and other fields. Heat treatment of metal bars involves processes such as heating, holding, and cooling to change their internal structure, thereby optimizing their mechanical and physical properties to meet the needs of different application scenarios.

[0003] In existing methods of heat-treating metal bars, the heat treatment furnace cavity is supported by a partition material. However, due to the high temperature environment, the partition material is prone to deformation, resulting in unstable support of the bars and easy bending of the bars. This leads to insufficient heat treatment, unevenness, and difficulty in subsequent straightening. At the same time, it is not convenient to adjust and limit the position according to the needs during bar processing, which limits the flexibility of use. Utility Model Content

[0024] Please see Figure 1-4 As shown, a heat treatment fixture for metal bars includes a support plate 1, a support plate 2 disposed on one side of the support plate 1, and a stabilizing plate 3 fixedly connected to the top of the support plate 1. Multiple support plates 2 are fixed by two support plates 1, and the support plate 3 with through slots facilitates support of the bars. Gaps are left between the annealed bars. A support assembly 4 is disposed on the top of the support plate 1. The support assembly 4 includes a support column 41 fixedly connected to the top of the support plate 1, a connecting column 42 slidably connected to the inner side of the support column 41, and a connecting plate 43 fixedly connected to the top of the connecting column 42. Multiple sets of support plates 1 and support plates 2 can be easily stacked and placed using four sets of support columns 41, connecting columns 42, and connecting plates 43 to form a material rack. A positioning rod 44 is fixedly connected to one side of the connecting column 42. Under the action of the positioning rod 44, the raising and lowering of the connecting column 42 under the limit of the support column 41 is easily controlled, thereby adjusting the support column 41. The overall height of the support plate 1 and the connecting column 42 facilitates the adjustment of the placement gap between each set of support plates 1 and tray 2, promotes uniform heating, and improves the heat treatment effect. The limiting component 5 is set on one side of the support plate 1. The limiting component 5 includes a limiting plate 51 set on one side of the support plate 1. Through the cooperation of two limiting plates 51, it is easy to limit the bar placed on the highest layer and improve the stability effect. A first adjusting rod 52 is fixedly connected to one side of the limiting plate 51. The limiting plate 51 is supported by two first adjusting rods 52. A first fixing frame 53 is set on the outer side of the first adjusting rod 52. The first adjusting rod 52 is slidably connected to the first fixing frame 53.

Under the support of the first fixing frame 53, the position of the limiting plate 51 can be flexibly adjusted by moving the first adjusting rod 52, and the first adjusting rod 52 is fixed by the first stabilizing block 54.

[0025] refer to Figure 1 , Figure 2 and Figure 3 As shown, one side of the support column 41 is fixedly connected to one end of the stabilizing plate 3, and the other side of the support plate 1 is fixedly connected to the fixing plate 6. The top of the fixing plate 6 is fixedly connected to the positioning plate 7. The fixing plates 6 are installed on the side of the two support plates 1 away from the support plate 2. The positioning plate 7 is supported and fixed by the fixing plates 6. The positioning plate 7 has a positioning groove 8 inside. The outer side of the positioning rod 44 is slidably connected to the inner side of the positioning groove 8. One end of the positioning rod 44 is provided with a threaded layer 9. Nuts 10 are provided on both sides of the positioning plate 7. The inner side of the nut 10 is threadedly connected to the outer side of the threaded layer 9. By controlling the positioning rod 44 to slide and rise in the positioning groove 8, the connecting column 42 and the connecting plate 43 are driven to rise and fall. Under the action of the two nuts 10, the position of the positioning rod 44 can be fixed, the lifting support height can be easily adjusted, and the practicality can be enhanced.

[0026] refer to Figure 1 and Figure 4 As shown, a first threaded rod 11 is threadedly connected to the inner side of the first fixing bracket 53. One end of the first threaded rod 11 is internally installed and connected to the first stabilizing block 54. Under the support of the first fixing bracket 53, the position of the first stabilizing block 54 can be easily adjusted by the first threaded rod 11, so that the first stabilizing block 54 can press and fix or loosen the first adjusting rod 52. A nut can be used between the first threaded rod 11 and the first fixing bracket 53, so that the nut locks the first threaded rod 11 and the first fixing bracket 53, further improving the stabilizing effect. A second adjusting rod 12 is fixedly connected to the bottom of the first fixing bracket 53. A second fixing bracket 13 is provided on the outer side of the second adjusting rod 12. The section rod 12 is slidably connected to the second fixed frame 13. A mounting plate 14 is fixedly connected to one side of the second fixed frame 13. One side of the mounting plate 14 is fixedly connected to one side of the support plate 1. The mounting plate 14 supports the second fixed frame 13. A second threaded rod 15 is threadedly connected to the inner side of the second fixed frame 13. A second stabilizing block 16 is provided at one end of the second threaded rod 15. Through the cooperation of the second threaded rod 15, the second stabilizing block 16 and the second fixed frame 13, it is convenient to loosen or tighten the second adjusting rod 12. By adjusting the position of the second adjusting rod 12, the height of the limiting plate 51 can be conveniently adjusted under the connection of the first fixed frame 53 and the first adjusting rod 52.

[0027] Working Principle: During use, multiple support plates 2 are fixed by two support plates 1, facilitating the placement of multiple bars. Gaps are left between the annealed bars. Supported by four sets of support columns 41, connecting columns 42, and connecting plates 43, multiple sets of support plates 1 and support plates 2 are easily stacked to form a material rack for easy loading into the furnace. The positioning rod 44 slides and rises within the positioning groove 8, thereby causing the connecting columns 42 and connecting plates 43 to rise and fall under the limit of the support columns 41. The appropriate height can be adjusted as needed. The positioning plate 7, threaded layer 9, and two nuts 10 fix the position of the positioning rod 44, ensuring the stability of the height of the connecting columns 42 and connecting plates 43. The overall height of the support columns 41, connecting columns 42, and connecting plates 43 can be easily adjusted, facilitating the adjustment of the stacking gaps of each set of support plates 1 and support plates 2. This achieves layered support for the bars, increasing the furnace loading capacity, saving manufacturing costs, promoting uniform heating, and improving heat treatment efficiency. As a result, the occurrence of bar bending is reduced, making the microstructure of the annealed bars more uniform and facilitating subsequent straightening. This also improves the yield. Supported by the mounting plate 14, two first adjusting rods 52 facilitate the support of a limiting plate 51. Supported by the first fixing frame 53, the first adjusting rods 52 can be easily controlled to move the limiting plate 51, adjusting its position. Once the position is determined, the first threaded rod 11 causes the first stabilizing block 54 to descend and fix the first adjusting rod 52. Through the cooperation of the second threaded rod 15, the second stabilizing block 16, and the second fixing frame 13, the second adjusting rod 12 can be easily loosened or tightened. By adjusting the position of the second adjusting rod 12, and with the connection of the first fixing frame 53 and the first adjusting rod 52, the height of the limiting plate 51 can be easily adjusted, allowing for flexible adjustment of its position as needed. The cooperation of the two limiting plates 51 facilitates the limiting of bars placed on the highest layer, improving stability.
