Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to an accessory for annealing, and in particular to an annealing material frame. Background Technology

[0002] Annealing is a metal heat treatment process that involves slowly heating metal to a certain temperature, holding it for a sufficient time, and then cooling it at a suitable rate. During annealing, an annealing frame is required to hold the parts.

[0003] The existing annealing frame consists of a base plate and a frame surrounding the base plate, which are welded together. The frame has multiple through holes. As a result, the welded joints of the annealing frame are prone to cracking due to temperature changes during use, which shortens the service life of the annealing frame. In addition, the holes in the frame cause the temperature of the workpiece near the frame to differ from that of the workpiece inside the frame, affecting the annealing efficiency and annealing effect. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an annealing frame with a stable structure and good annealing effect.

[0005] The purpose of this utility model can be achieved through the following technical solution: an annealing material frame, including a base plate and an outer frame surrounding the base plate, characterized in that a through hole is provided at the center of the base plate, and an inner frame that surrounds the through hole and is hollow is connected to the base plate, the inner frame and the outer frame are arranged on the same side, the base plate, the outer frame and the inner frame are integrally cast structures, and the base plate, the outer frame and the inner frame all have multiple through slots.

[0006] In the aforementioned annealing frame, the bottom plate is annular, and both the outer frame and the inner frame are cylindrical.

[0007] In the aforementioned annealing frame, the outer wall of the outer frame has several circumferentially distributed reinforcing ribs 1, and the top edge of the outer frame has an annular reinforcing rib 2, and the bottom edge of the outer frame has an annular reinforcing rib 3. The bottom of the reinforcing rib 1 extends to the reinforcing rib 3, and the top of the reinforcing rib 1 extends to the reinforcing rib 2. The outer wall of the inner frame has several circumferentially distributed reinforcing ribs 4, and the top edge of the inner frame has an annular reinforcing rib 5, and the bottom edge of the inner frame has an annular reinforcing rib 6. The bottom of the reinforcing rib 4 extends to the reinforcing rib 6, and the top of the reinforcing rib 4 extends to the reinforcing rib 4. The bottom of the base plate has several circumferentially distributed reinforcing ribs 7, the outer end of the reinforcing rib 7 extends to the reinforcing rib 3, and the inner end of the reinforcing rib 7 extends to the reinforcing rib 6.

[0008] In the aforementioned annealing frame, the inner wall of the inner frame is fixed with symmetrically arranged connecting ribs, and the two connecting ribs are connected by a crossbeam. The crossbeam is axially higher than the inner frame, and the bottom of the crossbeam has a symmetrical inclined surface that slopes downward towards the corresponding connecting rib. The connecting ribs and the crossbeam are integrally cast with the inner frame.

[0009] In the aforementioned annealing frame, a curved limiting rod is fixed to the outer wall of the reinforcing rib three. The limiting rod and the reinforcing rib three are integrally cast structures, and both ends of the limiting rod have multiple connecting plates extending to the reinforcing rib three.

[0010] In the aforementioned annealing frame, the bottom surfaces of reinforcing ribs three, six, and seven each have several spaced grooves.

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1 and Figure 2 As shown, this annealing frame includes a base plate 1 and an outer frame 2 surrounding the base plate 1. A through hole is formed at the center of the base plate 1. An inner frame 3, which surrounds the through hole and is hollow, is connected to the base plate 1. The inner frame 3 is located on the same side as the outer frame 2. The base plate 1, outer frame 2, and inner frame 3 are an integrally cast structure. Each of the base plate 1, outer frame 2, and inner frame 3 has multiple through slots 4. In this embodiment, the slots 4 are round holes; in actual manufacturing, the slots 4 can be strip-shaped or rectangular holes.

[0017] This annealing frame is integrally cast, with a stable structure, good load-bearing capacity, and long service life. Moreover, the inner frame 3 and multiple slots 4 ensure good heat exchange, guaranteeing annealing efficiency and annealing effect.

[0018] To elaborate further, the base plate 1 is annular, while the outer frame 2 and inner frame 3 are both cylindrical. This compact structure, with consistent spacing between the outer frame 2 and inner frame 3, ensures uniform annealing efficiency and effect for each workpiece.

[0019] The outer frame has eight circumferentially distributed reinforcing ribs 5 on its outer wall, and a ring-shaped reinforcing rib 6 on its top edge and a ring-shaped reinforcing rib 7 on its bottom edge. The bottom of reinforcing rib 5 extends to reinforcing rib 7, and the top of reinforcing rib 5 extends to reinforcing rib 26. The inner frame has four circumferentially distributed reinforcing ribs 8 on its outer wall, and a ring-shaped reinforcing rib 9 on its top edge and a ring-shaped reinforcing rib 10 on its bottom edge. The bottom of reinforcing rib 8 extends to reinforcing rib 10, and the top of reinforcing rib 8 extends to reinforcing rib 10. The bottom of the base plate 1 has eight circumferentially distributed reinforcing ribs 11 on its bottom, with the outer end of reinforcing rib 11 extending to reinforcing rib 37 and the inner end of reinforcing rib 11 extending to reinforcing rib 10. This design provides high structural strength, good load-bearing capacity, and prevents cracking due to thermal deformation, resulting in a long service life.

[0020] The inner wall of the inner frame 3 is fixed with symmetrically arranged connecting ribs 12. The two connecting ribs 12 are connected by a crossbeam 13. The crossbeam 13 is axially higher than the inner frame 3. The bottom of the crossbeam 13 has a symmetrical inclined surface that slopes downward towards the corresponding connecting rib 12. The connecting ribs 12 and the crossbeam 13 are integrally cast with the inner frame 3. The crossbeam 13 and the connecting ribs 12 have high structural strength. The crossbeam 13 is used for hanging by hooks. The hooks are guided by the inclined surface and abut against the middle position of the bottom of the crossbeam 13. This prevents the annealing material frame from shaking during handling and makes handling convenient. In addition, during annealing, when the annealing material frames are stacked, the crossbeam 13 of the lower annealing material frame is inserted into the inner frame 3 of the upper annealing material frame. The crossbeam 13 acts as a limit to prevent the stacked annealing material frames from tipping over.

[0021] A curved limiting rod 14 is fixed to the outer wall of the reinforcing rib 3 7. The limiting rod 14 and the reinforcing rib 3 7 are integrally cast structures, and both ends of the limiting rod 14 have multiple connecting plates 15 extending to the reinforcing rib 3 7. The connection strength between the limiting rod 14 and the reinforcing rib 3 7 is high. When the annealing material frames are stacked, the limiting rods 14 of each annealing material frame face the same direction. A vertical rod passes through the hole formed by each limiting rod 14 and the corresponding reinforcing rib 3 7, thus limiting the stacked annealing material frames and preventing them from tipping over.

[0022] The bottom surfaces of reinforcing ribs 3-7, 6-10, and 7-11 all have several spaced grooves 16. The grooves 16 reduce contact interference, facilitate the stacking of each annealed material frame, and also increase the allowance for thermal deformation, reduce stress concentration, further prevent cracks from appearing at reinforcing ribs 3-7, 6-10, and 7-11 due to thermal deformation, and extend their service life.
