Description

Technical Field

[0001] This utility model relates to the field of tempering technology, specifically a continuous tempering device for nut production. Background Technology

[0002] Tempering is a crucial heat treatment step in nut production, typically performed after quenching. Its core function is to eliminate internal stresses generated during quenching and adjust the material's toughness and hardness to meet the mechanical performance requirements of nuts under different operating conditions. By rationally selecting the tempering process, nuts can achieve a performance leap from ordinary fasteners to high-reliability critical components, and their quality directly affects the operational safety and lifespan of equipment.

[0003] The mesh belt tempering furnace transports nuts through a mesh belt, sequentially passing them through stages such as preheating, heating, homogenization, holding, and cooling to achieve the tempering heat treatment of metal products, with precise control of temperature and holding time. However, during the tempering process, operators typically stack the nuts directly on the stainless steel conveyor belt, resulting in uneven heating of the nuts, affecting the tempering efficiency and the mechanical properties of the nuts after tempering. Utility Model Content

[0004] To address the above deficiencies, this utility model provides a continuous tempering device for nut production, thereby solving the problem of continuous and uniform tempering in nut production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A continuous tempering apparatus for nut production, comprising: frame; The tempering furnace is fixed on the frame; The drive chains are arranged in a pair, opposite to each other, and are installed on both sides inside the frame. There are several V-shaped bearing plates, with both ends fixed to a set of opposite transmission chains, and the distance between adjacent sets of V-shaped bearing plates is sufficient to accommodate nuts; Several feeding hoppers are fixed at equal intervals on the machine frame; The material discharge holes are located at the bottom of several feeding hoppers; The inclined plate is installed at an angle inside the feed end of the frame and is higher than the V-shaped bearing plate. Electric actuator one, horizontally mounted on the inclined plate; A baffle plate is installed on the push end of the electric actuator and corresponds to several material discharge holes.

[0006] Furthermore, several disc feeders corresponding to the feeding hoppers are placed on one side of the frame. Each disc feeder is equipped with an electric actuator II at its discharge end, and a pusher plate is installed at the pushing end of the electric actuator II. The disc feeders can automatically feed nuts. With the electric actuator II pushing the pusher plate, the nuts can be pushed one by one into the corresponding feeding hopper. The feeding hopper then sends the nuts one by one between an adjacent set of V-shaped support plates.

[0007] Furthermore, the front end of the pusher plate has a rectangular notch corresponding to the nut, which facilitates the pusher plate to push the nut into the feeding hopper.

[0008] Furthermore, several V-shaped bearing plates are evenly perforated with several round holes to provide sufficient ventilation space and improve the tempering heating effect of the nuts.

[0009] Furthermore, the frame is equipped with a drive motor for driving a set of opposing transmission chains to rotate intermittently.

[0010] Furthermore, a collection box is placed at the discharge end of the frame, and the tempered nuts can be intermittently rotated by several V-shaped bearing plates and automatically fall into the collection box.

[0011] This utility model provides a continuous tempering device for nut production, which has the following advantages: by using several feeding hoppers and bottom baffles, the nuts that need to be tempered can be fed to the space between adjacent V-shaped bearing plates. The transmission chain drives the V-shaped bearing plates to rotate, which can prevent the nuts from stacking, thereby making the nuts heat more evenly, improving the tempering efficiency and the mechanical properties after tempering.

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] Please see Figures 1 to 5 As shown in the figure, this application provides a continuous tempering device for nut production, including a frame 1; a tempering furnace 2, fixed on the frame 1; a set of transmission chains 3, arranged opposite each other, installed on both sides inside the frame 1; several V-shaped bearing plates 4, both ends fixed on the set of opposite transmission chains 3, and the distance between adjacent sets of V-shaped bearing plates 4 is sufficient to accommodate nuts; several feeding hoppers 5, equidistantly fixed on the frame 1; discharge holes 6, respectively opened at the bottom of several feeding hoppers 5; an inclined plate 7, inclinedly installed inside the feeding end of the frame 1, and higher than the V-shaped bearing plates 4; an electric actuator 8, horizontally installed on the inclined plate 7; and a baffle plate 9, installed on the pushing end of the electric actuator 8, and corresponding to the several discharge holes 6.

[0020] In this embodiment, a set of relative transmission chains 3 drives several V-shaped support plates 4 to rotate intermittently. Several feeding hoppers 5 are fixed at equal intervals on the feeding end of the frame 1. During tempering, the electric actuator 8 uses a servo cylinder to drive the baffle plate 9 to move to the left, opening the dropping hole 6. Nuts in several feeding hoppers 5 can fall one by one through the dropping hole 6 between adjacent sets of V-shaped support plates 4 to prevent stacking. The size of the dropping hole 6 is larger than the size of the nut to prevent jamming. The height of the inclined plate 7 is higher than that of the V-shaped support plates 4 to prevent interference when several V-shaped support plates 4 rotate intermittently. The nut dropping frequency is the same as the intermittent rotation frequency of several V-shaped support plates 4, which can be implemented by programming with a PLC. The nuts are tempered in a tempering furnace 2. The tempering furnace 2 uses resistance wire or gas heating. The hot air is evenly convectioned in the furnace through the air guide hood and strong circulating fan, so that the nuts are heated more evenly, improving the tempering efficiency and the mechanical properties after tempering.

[0021] In some embodiments, a plurality of disc feeders 10 corresponding to the feeding hoppers 5 are placed on one side of the frame 1. The discharge end of the disc feeders 10 is equipped with electric actuators 11, and the pushing end of the electric actuators 11 is equipped with a pusher plate 12. The disc feeders 10 can automatically feed nuts. With the electric actuators 11 pushing the pusher plate 12, the nuts can be pushed one by one into the corresponding feeding hoppers 5. The feeding hoppers 5 then send the nuts one by one between an adjacent set of V-shaped bearing plates 4. The electric actuators 11 can be servo cylinders.

[0022] In some embodiments, the front end of the pusher plate 12 has a rectangular notch 13 corresponding to the nut, so that the pusher plate 12 can push the nut into the feeding hopper 5.

[0023] In some embodiments, several V-shaped support plates 4 are evenly provided with several round holes 14 to retain sufficient ventilation space and improve the tempering heating effect of the nuts.

[0024] In some embodiments, a drive motor 15 is mounted on the frame 1 to drive a set of opposing transmission chains 3 to rotate intermittently.

[0025] In some embodiments, a collection box 16 is placed at the discharge end of the frame 1. After tempering, the nuts can be intermittently rotated by several V-shaped bearing plates 4 and automatically fall into the collection box 16.

[0026] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
