Description

Technical Field

[0001] This utility model relates to the technical field of nut processing equipment, and more specifically, to a nut blank processing annealing device. Background Technology

[0002] Annealing is a metal heat treatment process that involves slowly heating a metal to a certain temperature, holding it for a sufficient time, and then cooling it at an appropriate rate. The purpose is to reduce hardness, improve machinability, eliminate residual stress, stabilize dimensions, reduce deformation and cracking tendency, refine grains, adjust microstructure, and eliminate microstructural defects.

[0003] In existing technology, when annealing nuts, the nuts are generally placed in an annealing chamber, and then heated and cooled to perform the annealing process. However, since nuts are generally small, a large number of nuts piled together result in the outer nuts heating up faster than the inner nuts, affecting the uniformity of heating and consequently impacting the quality of the nuts. Utility Model Content

[0004] The purpose of this invention is to solve the problem of uneven heating of nuts leading to poor quality, and to design an annealing device for nut blank processing.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: an annealing device for processing nut blanks, comprising an annealing chamber, a fixing plate installed inside the annealing chamber, a heater installed below the fixing plate inside the annealing chamber, a holding box placed inside the annealing chamber, multiple partitions installed inside the holding box, the partitions dividing the holding box into multiple holding spaces, nut blanks placed in the holding spaces, a sealing plate installed at the upper end of the annealing chamber, a sealing block installed at the lower end of the sealing plate, the lower end of the sealing block extending into the holding spaces, a hot air circulation system installed on the annealing chamber, and an air guide pipe installed on the holding box, the hot air circulation system allowing hot air to circulate through the air guide pipe within the multiple holding spaces.

[0006] Furthermore, an air inlet pipe is installed on one side of the lower end of the container. The air inlet pipe is located at the lower end of the container space at the outermost edge of the container. Starting from one side of the air inlet pipe, the upper end of the partitions with odd-numbered numbers have air guides, while the upper end of the partitions with even-numbered numbers do not have air guides. The air guide pipe is located below the partitions without air guides and connects the container spaces on both sides of the partition.

[0007] Furthermore, a first inlet / outlet is provided on one side of the fixed plate, and the lower end of the air inlet pipe extends to the bottom of the fixed plate through the inlet / outlet. Multiple second inlets / outlets are provided on the fixed plate, and the position and number of the second inlets / outlets correspond one-to-one with the air guide pipes. The lower end of the air guide pipes extends to the bottom of the fixed plate through the second inlets / outlets.

[0008] Furthermore, an intercepting net is installed at the upper end of the air inlet pipe and the air guide pipe.

[0009] Furthermore, the portion of the air duct located below the fixed plate is spiral-shaped.

[0010] Furthermore, the hot air circulation system includes a circulation pump installed outside the annealing chamber. The inlet end of the circulation pump is equipped with an air suction pipe. An air exchange port is opened on one side of the upper end of the sealing plate. The air exchange port is located above the holding space on the side furthest from the air inlet pipe. The inlet end of the air suction pipe is connected to the air exchange port. An exhaust pipe is installed at the outlet end of the circulation pump. The outlet end of the exhaust pipe extends to the bottom of the fixed plate inside the annealing chamber.

[0011] The beneficial effects of this utility model are as follows: the partition divides the holding box into multiple holding spaces, which can reduce the number of nuts piled up. The hot air circulation system and air guide pipe can make hot air flow in the holding space, thereby ensuring the quality of the nuts by ensuring the uniformity of heating.

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] This utility model provides, for example Figure 1-3 The annealing apparatus for processing nut blanks shown includes an annealing chamber 1, a fixing plate 2 installed inside the annealing chamber 1, a heater 3 installed below the fixing plate 2 inside the annealing chamber 1, a holding box 4 placed inside the annealing chamber 1, multiple partitions 5 installed inside the holding box 4, the partitions 5 dividing the holding box 4 into multiple holding spaces 6, nut blanks placed in the holding spaces 6, a sealing plate 7 installed at the upper end of the annealing chamber 1, a sealing block 8 installed at the lower end of the sealing plate 7, the lower end of the sealing block 8 extending into the holding spaces 6, a hot air circulation system 9 installed on the annealing chamber 1, and an air guide pipe 10 installed on the holding box 4. The hot air circulation system 9 allows hot air to circulate through the air guide pipe 10 within the multiple holding spaces 6.

[0019] The annealing process of this device for nuts is as follows: Open the sealing plate 7, add an appropriate amount of nut blank to the holding space 6, then cover the upper end of the annealing box 1 with the sealing plate 7, and make the lower end of the sealing block 8 extend into the holding space 6. Start the heater 3 to heat, and then draw hot air into the holding space 6 through the hot air circulation system 9 and the air guide pipe 10 to anneal the nut blank. The annealing temperature can be adjusted by changing the temperature of the heater 3. After the nut blank is processed, open the sealing plate 7 and take out the nut blank.

[0020] Refer to the instruction manual appendix Figure 1 An air inlet pipe 11 is installed on one side of the lower end of the holding box 4. The air inlet pipe 11 is located at the lower end of the holding space 6 at the outermost edge of the holding box 4. Starting from the side of the air inlet pipe 11, the upper end of the partition 5 with odd-numbered order has an air guide 12, while the upper end of the partition 5 with even-numbered order does not have an air guide 12. The air guide pipe 10 is located below the partition 5 without an air guide 12 and connects the holding spaces 6 on both sides of this partition 5. Hot air can enter the holding space 6 at the outermost edge through the air inlet pipe 11, and then enter the adjacent holding space 6 through the air guide 12. Then, the hot air can enter the next holding space 6 again through the lower air guide pipe 10, so that the hot air can flow in a continuous stream in multiple holding spaces 6, which is convenient for heating all the nut blanks.

[0021] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 The fixed plate 2 has a first inlet / outlet 13 on one side. The lower end of the air inlet pipe 11 extends to the bottom of the fixed plate 2 through the inlet / outlet. The fixed plate 2 has multiple second inlets / outlets 14. The position and number of the second inlets / outlets 14 correspond one-to-one with the air duct 10. The lower end of the air duct 10 extends to the bottom of the fixed plate 2 through the second inlet / outlet 14, which facilitates the flow of hot air and heats the air duct 10 to ensure the temperature of the hot air.

[0022] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 An intercepting net 15 is installed at the upper end of the air inlet pipe 11 and the air guide pipe 10 to prevent the nut blank from falling off.

[0023] Refer to the instruction manual appendix Figure 1 The portion of the air duct 10 located below the fixed plate 2 is spiral-shaped, which can prolong the duration of the hot air in the air duct 10 below the fixed plate 2, thereby ensuring the temperature of the hot air.

[0024] Refer to the instruction manual appendix Figure 1 The hot air circulation system includes a circulation pump 16 installed on the outside of the annealing chamber 1.

The ventilation port 18 is located above the holding space 6 on the side furthest from the air inlet pipe 11. The inlet end of the suction pipe 17 is connected to the ventilation port 18. The outlet end of the circulation pump 16 is equipped with an exhaust pipe 19. The outlet end of the exhaust pipe 19 extends to the bottom of the fixing plate 2 inside the annealing chamber 1. When the circulation pump 16 is started, the circulation pump 16 can draw hot air through the suction pipe 17 and the ventilation port 18, and then discharge the hot air into the annealing chamber 1 through the exhaust pipe 19, thereby preventing hot air leakage and saving energy.
