Abstract
Description
Technical Field
[0001] This utility model relates to the field of nut processing technology, specifically to a temperature-controlled annealing device for nut production. Background Technology
[0002] Utility model application CN202223465982.0 discloses a recrystallization annealing device for nuts. The nut is heated using an electromagnetic heating coil, while a rotating shaft drives the nut to rotate intermittently, ensuring more even heating. During cooling, a lifting mounting shell immerses the nut in a cooling tank, improving cooling efficiency.
[0003] The aforementioned device uses a lifting mounting shell to immerse the nut in a cooling tank for cooling. The cooling time for the nut is relatively long. While the nut is cooling, there is no need to heat the next batch of nuts. After the nut has cooled down, the processed nut needs to be removed and the nut to be processed needs to be fixed on the lifting mounting shell. This process is time-consuming and inefficient. Utility Model Content
[0004] The purpose of this invention is to solve the above problems by designing a temperature-controlled annealing device for nut production.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A temperature-controlled annealing apparatus for nut production, comprising:
[0007] Fixed base;
[0008] A lifting roof panel is provided with multi-stage telescopic cylinders on both sides of the bottom of the lifting roof panel. The multi-stage telescopic cylinders are fixedly installed on a fixed base to enable the lifting roof panel to rise and fall.
[0009] A high-frequency quenching machine, which is fixedly installed on a lifting top plate, and has several electromagnetic heating coils installed at the bottom.
[0010] A cooling box, located between the two multi-stage telescopic cylinders;
[0011] A flip-grip assembly is used to position and clamp the nut, and the flip-grip assembly is disposed on the cooling box.
[0012] Furthermore, the flipping clamping assembly includes a flipping plate, which is rotatably connected inside the cooling box. A motor base is fixedly installed on one side of the cooling box, and a drive motor is installed on the motor base. The output end of the drive motor is fixedly connected to one end of the flipping plate. Several positioning seats are installed on both sides of the flipping plate, and the positioning seats are aligned with the positions of the electromagnetic heating coil.
[0013] Furthermore, the flipping clamping assembly also includes multiple sets of sliding clamping plates. Each positioning seat is provided with a set of guide grooves. Each set of sliding clamping plates is slidably connected to each set of guide grooves. A spring is installed in the guide groove, and one end of the spring is fixedly connected to the tail end of the sliding clamping plate.
[0014] Furthermore, a stirring shaft is rotatably connected inside the cooling box, and a rotary motor is mounted on one side of the cooling box via a bracket. The output end of the rotary motor is fixedly connected to one end of the stirring shaft, and several stirring plates are installed around the stirring shaft.
[0015] The stirring shaft drives the stirring plate to rotate, stirring the coolant in the cooling box, making the coolant temperature uniform and improving the annealing effect.
[0016] Furthermore, a drain hose is connected to one side of the cooling tank, and a valve is connected to the drain hose.
[0017] The drain hose facilitates the drainage of coolant from the cooling tank.
[0018] Furthermore, the liquid level in the cooling tank remains horizontal with the surface of the positioning seat on the back of the flip plate.
[0019] Compared with existing technologies, this technical solution has the following beneficial effects:
[0020] 1. The rotating plate is driven by the drive motor to rotate the positioning seat and nut, so that the positioning seat on the surface of the rotating plate rotates the nut into the cooling box. The nut is in the coolant, and the positioning seat on the back of the rotating plate faces upward, so that the nut can be fixed on the positioning seat. While cooling the previous batch of nuts, another batch of nuts can be heated, which facilitates the annealing operation of the nuts without stopping the machine, thus improving work efficiency.
[0021] 2. The nut is held in place by two sliding clamping plates, which makes it easier to hold and remove the nut, thus improving work efficiency. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0029] This utility model provides, for example Figure 1-4 The illustrated nut production temperature-controlled annealing apparatus includes:
[0030] Fixed base 1;
[0031] The lifting roof panel 2 has multi-stage telescopic cylinders 3 on both sides of its bottom. The multi-stage telescopic cylinders 3 are fixedly installed on the fixed base 1 to make the lifting roof panel 2 rise and fall.
[0032] High-frequency quenching machine 4 is fixedly installed on the lifting top plate 2. Several electromagnetic heating coils 5 are installed at the bottom of the high-frequency quenching machine 4.
[0033] Cooling box 6, which is located between two multi-stage telescopic cylinders 3;
[0034] The flip-grip assembly 7 is used to position and clamp the nut, and is located on the cooling box 6.
[0035] The nut to be processed is clamped and fixed on the surface of the flip-grip assembly 7. The multi-stage telescopic cylinder 3 starts working, and the telescopic end of the multi-stage telescopic cylinder 3 extends and retracts, causing the lifting top plate 2 to descend. The lifting top plate 2 causes the high-frequency quenching machine 4 and the electromagnetic heating coil 5 to descend, so that the nut on the surface of the flip-grip assembly 7 is located inside the electromagnetic heating coil 5. The high-frequency quenching machine 4 starts working, heating the nut through the electromagnetic heating coil 5. After the nut is heated, the multi-stage telescopic cylinder 3 starts working, and the telescopic end of the multi-stage telescopic cylinder 3 extends, causing the lifting top plate 2 to rise. The lifting top plate 2 causes the high-frequency quenching machine... 4. When the electromagnetic heating coil 5 rises and resets, the flipping clamping assembly 7 begins to rotate, causing the nuts on the surface of the flipping clamping assembly 7 to flip and enter the cooling box 6. The nuts are cooled by the coolant in the cooling box 6. At the same time, the nuts can be clamped and fixed to the back of the flipping clamping assembly 7. The electromagnetic heating coil 5 then heats the nuts on the back of the flipping clamping assembly 7. While cooling the previous batch of nuts, another batch of nuts can be heated, which facilitates the annealing operation of the nuts without stopping the machine, thus improving work efficiency.
[0036] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 The flip clamping assembly 7 includes a flip plate 8, which is rotatably connected inside the cooling box 6. A motor base 9 is fixedly installed on one side of the cooling box 6, and a drive motor 10 is installed on the motor base 9. The output end of the drive motor 10 is fixedly connected to one end of the flip plate 8. Several positioning seats 11 are installed on both sides of the flip plate 8. The positioning seats 11 are aligned with the position of the electromagnetic heating coil 5. The liquid level in the cooling box 6 is kept horizontal with the surface of the positioning seats 11 on the back of the flip plate 8.
[0037] The nut is connected to the positioning seat 11. The drive motor 10 starts to work. The output end of the drive motor 10 drives the flip plate 8 to rotate, so that the positioning seat 11 on the surface of the flip plate 8 drives the nut to rotate into the cooling box 6. The nut is in the coolant, so that the positioning seat 11 on the back of the flip plate 8 faces upward. The nut can be fixed on the positioning seat 11. While cooling the previous batch of nuts, another batch of nuts can be heated, which facilitates the annealing operation of the nuts without stopping the machine, thus improving work efficiency.
[0038] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 4 The flip clamping assembly 7 also includes multiple sets of sliding clamping plates 12. Each positioning seat 11 is provided with a set of guide grooves 13. Each set of sliding clamping plates 12 is slidably connected to each set of guide grooves 13. A spring 14 is installed in the guide groove 13. One end of the spring 14 is fixedly connected to the tail end of the sliding clamping plate 12.
[0039] When clamping the nut, the two sliding clamping plates 12 on the positioning seat 11 are pushed outward. The sliding clamping plates 12 slide along the guide groove 13 and apply pressure to the spring 14. The spring 14 deforms and contracts under pressure, and the two sliding clamping plates 12 move away from each other. The nut is placed on the positioning seat 11. After the sliding clamping plates 12 are released, the two sliding clamping plates 12 move closer to each other under the action of the spring 14 to clamp the nut. This makes it easier to clamp and remove the nut, thus improving work efficiency.
[0040] Refer to the instruction manual appendix Figure 3 A stirring shaft 15 is rotatably connected inside the cooling box 6. A rotary motor 16 is mounted on one side of the cooling box 6 via a bracket. The output end of the rotary motor 16 is fixedly connected to one end of the stirring shaft 15. Several stirring plates 17 are installed around the stirring shaft 15.
[0041] The rotary motor 16 starts working, and the output end of the rotary motor 16 drives the stirring shaft 15 to rotate. The stirring shaft 15 drives the stirring plate 17 to rotate and stir the coolant in the cooling box 6, so that the temperature of the coolant in the cooling box 6 is uniform and the annealing effect is improved.
[0042] Refer to the instruction manual appendix Figure 3 A drain hose 18 is connected to one side of the cooling tank 6, and a valve 19 is connected to the drain hose 18.
[0043] After valve 19 is opened, the coolant in the cooling tank 6 can be drained through the drain hose 18.
[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
