Description

Technical Field

[0001] This utility model relates to the field of firing support technology, and in particular to a stress-relieving firing support for PCBN composite sheets. Background Technology

[0002] During the sintering process of composite sheets under high temperature and high pressure, large internal stresses are easily generated due to the difference in the thermal expansion coefficients of the materials. These residual stresses can significantly affect the performance and service life of the composite sheets, such as causing interface cracks, delamination, or failure due to thermal shock during use. Therefore, it is crucial to take effective measures to eliminate or reduce internal stresses during the manufacturing process.

[0003] The existing stress-relief firing racks are directly fixed inside the heating furnace. After multiple trays are pushed onto the placement plate, the firing racks are inside the furnace after heating, making it difficult for workers to remove the materials. Workers need to remove the trays one by one, which takes a long time and is not conducive to the factory's production efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology. When using the existing stress-relief firing rack, it is directly fixed in the heating furnace. After multiple trays are pushed into the placement plate, it is difficult for workers to remove the materials after heating because the firing rack is in the heating furnace. Workers need to remove the trays one by one, which takes a long time and is not conducive to the production efficiency of the factory. Therefore, a stress-relief firing rack for PCBN composite sheets is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A stress-relieving firing support frame for PCBN composite sheets includes a firing support frame body and placement plates, wherein multiple placement plates are mounted on the firing support frame body. The firing rack body is equipped with limiting components, which include a fixed box, a sliding rod, a moving plate, a connecting rod, a fixing ring, a locking ring, and a bolt. Two fixed boxes are fixedly connected to the outer surface of the firing rack body, and two sliding rods are fixedly connected inside the fixed boxes. The sliding rods pass through the moving plate and are slidably connected to it. The connecting rod is fixedly connected to the moving plate, and the fixing ring is fixedly connected to the connecting rod. The locking ring is slidably connected inside the fixing ring. An arc-shaped through hole is formed on the outer surface of the fixing ring, and the bolt is slidably connected inside the arc-shaped through hole. The bolt is fixedly connected to the locking ring.

[0006] Preferably, the outer surface of the firing rack body is fixedly connected to two guide rails, and multiple rollers are rotatably connected inside the guide rails. The outer surface of the locking ring is provided with a screw hole, and the outer surface of the fixing ring is threaded with a bolt, which is threadedly connected to the screw hole.

[0007] Preferably, a straight rod is slidably connected to the outer surface of the fixed box, and multiple circular holes are opened on the outer surface of the connecting rod. The straight rod passes through the fixed box and is slidably connected in the circular holes. A tension spring is provided between one end of the straight rod and the fixed box.

[0008] Preferably, two round rods are fixedly connected inside the firing support body, and multiple sliders are slidably connected to the outer surface of the round rods, with the sliders slidably connected to the firing support body.

[0009] Preferably, the slider passes through the body of the firing rack and is fixedly connected to the placement plate. The placement plate is slidably connected to the body of the firing rack. A limit hole is opened on the outer surface of the slider, and multiple limit rods are slidably connected to the outer surface of the body of the firing rack.

[0010] Preferably, a straight spring is sleeved on the outer surface of the limiting rod, a pull plate is fixedly connected to the outer surface of the firing rack body, the limiting rod passes through the pull plate and is slidably connected to the pull plate, and the limiting rod passes through the firing rack body and is slidably connected in the limiting hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1.

[0018] Reference Figure 1 A stress-relieving firing rack for PCBN composite sheets includes a firing rack body 1 and a placement plate 2. The placement plate 2 is used to place a tray, and multiple placement plates 2 are installed on the firing rack body 1.

[0019] Reference Figure 2 The main body 1 of the firing rack is equipped with limiting components, including a fixed box 5, a sliding rod 6, a moving plate 7, a connecting rod 8, a fixed ring 9, a locking ring 10, and a bolt 11. The two fixed boxes 5 are fixedly connected to the outer surface of the main body 1 of the firing rack. The fixed boxes 5 are hollow. The two sliding rods 6 are fixedly connected inside the fixed boxes 5. The sliding rods 6 pass through the moving plate 7 and are slidably connected to the moving plate 7. The connecting rod 8 is fixedly connected to the moving plate 7. The fixed ring 9 is fixedly connected to the connecting rod 8. The fixed ring 9 is open. The locking ring 10 is slidably connected inside the fixed ring 9. The locking ring 10 is arc-shaped. An arc-shaped through hole is opened on the outer surface of the fixed ring 9. The bolt 11 is slidably connected inside the arc-shaped through hole. The cooperation between the bolt 11 and the bolt 12 can control the movement trajectory of the locking ring 10. The bolt 11 is fixedly connected to the locking ring 10.

[0020] Reference Figure 2 , 5The locking ring 10 has a screw hole on its outer surface, and the fixing ring 9 has a bolt 12 threadedly connected to its outer surface. The bolt 12 is threadedly connected to the screw hole, and the bolt 12 mates with the screw hole. A straight rod 13 is slidably connected to the outer surface of the fixing box 5. The connecting rod 8 has multiple round holes on its outer surface. The straight rod 13 passes through the fixing box 5 and is slidably connected in the round holes. A tension spring is provided between one end of the straight rod 13 and the fixing box 5. Figure 5 As shown, two guide rails 3 are fixedly connected to the outer surface of the firing rack body 1, and multiple rollers 4 are rotatably connected inside the guide rails 3. There are three rollers 4, which are located at the lower end of the firing rack body 1.

[0021] Reference Figure 3-4 A pull plate 18 is fixedly connected to the outer surface of the firing rack body 1, and multiple limiting rods 16 are slidably connected to the outer surface of the firing rack body 1. The limiting rods 16 pass through the pull plate 18 and are slidably connected to the pull plate 18, such as... Figure 4 As shown, two round rods 14 are fixedly connected inside the firing rack body 1. Multiple sliders 15 are slidably connected to the outer surface of the round rods 14. The sliders 15 are slidably connected to the firing rack body 1, pass through the firing rack body 1, and are fixedly connected to the placement plate 2. The placement plate 2 is slidably connected to the firing rack body 1. Limiting holes are opened on the outer surface of the sliders 15. A straight spring 17 is sleeved on the outer surface of the limiting rod 16. The limiting rod 16 passes through the firing rack body 1 and is slidably connected in the limiting hole. The outer surfaces of the above-mentioned parts are all coated with a high-temperature resistant coating to avoid them from being affected by high temperatures.

[0022] In this invention, the firing rack body 1 is first placed into the heating furnace. Under the action of the rollers 4, the firing rack body 1 can be easily pushed into the heating furnace. When the firing rack body 1 is fully inside the heating furnace, the straight rod 13 is pulled out from the round hole of the connecting rod 8. The connecting rod 8 is then pulled, causing the fixing ring 9 at one end of the connecting rod 8 to be in the fixing rod position inside the heating furnace. At this time, the fixing ring 9 is in the open state, wrapping around the fixing rod. The straight rod 13 is then released, and under the action of the tension spring, it enters the round hole of the connecting rod 8, re-fixing the connecting rod 8. Then, the locking ring 10 is pulled from one end of the fixing ring 9 to the other end using the bolt 11. Under the action of the locking ring 10, the fixing ring 9 is closed. Finally, the bolt 12 is screwed into the locking ring 10, completing the fixing work between the locking ring 10 and the fixing ring 9. After the heat treatment of the items on the rack body 1 is completed and they have cooled down, the furnace is opened, and the above steps are reversed. The fixing ring 9 is opened, and then the fixing ring 9 is moved to a position closer to the fixing box 5 via the connecting rod 8. At this time, the moving plate 7 moves into the fixing box 5, completing the unfixing of the rack body 1. The worker can then pull the rack body 1 to remove it from the furnace. The new rack body 1 and the rack body 1 without the tray are then pushed into the furnace. The worker can continue to heat the PCBN composite sheet. The entire material handling process is simple and fast. The worker does not need to work in the furnace area for a long time, ensuring the worker's personal safety. At the same time, it will not delay the new round of production, greatly improving work efficiency and thus effectively increasing the factory's output.

[0023] By sliding between the connecting rod 8 and the slide rod 6, the firing rack body 1 can be adapted to heating furnaces of different widths. The fixed distance can be adjusted to ensure the flexibility of fixing the firing rack body 1. For trays of different heights, the placement plate 2 can be adjusted. Pulling the limiting rod 16 pulls it out of the limiting hole of the slider 15. The straight spring 17 is compressed due to the resistance of the pull plate 18. At this time, the slider 15 can slide freely on the round rod 14. After adjusting the height of the placement plate 2, the limiting rod 16 is released. Under the action of the straight spring 17, the limiting rod 16 re-enters the limiting hole of the slider 15, and the slider 15 is fixed again, thus continuing to fix the placement plate 2. By adjusting the height of the placement plate 2, the firing rack body 1 can adapt to trays of different specifications, improving the practicality and flexibility of the firing rack body 1.
