Description

Technical Field

[0001] The present invention is a quenching device for fasteners, belonging to the field of fastener processing. Background Art

[0002] A quenching furnace is a device used for heat treatment of metal materials. By controlling the heating process, the material can reach the required hardness and strength. Fasteners are fed into the quenching furnace. According to the required temperature and material properties, appropriate heating temperature and time are set. Thus, when the quenching furnace works, it heats the fasteners. Since the volume of the fasteners is small, a batch of fasteners need to be added to the quenching chamber of the quenching furnace together, which is beneficial to improving the quenching efficiency and reducing the operation cost. However, the number of fasteners in a batch is large. After adding a large number of fasteners to the quenching chamber, the fasteners are in a static state and there is a situation where the fasteners overlap each other, resulting in uneven heating of the fasteners and affecting the quenching quality of the fasteners. Summary of the Invention

Two side plates are provided on the side of the linear groove away from the vibrating bowl, and the two side plates are symmetrically installed on the surface of the quenching furnace. Two inclined chutes are installed between the two side plates. The two chutes are arranged in parallel and there is a gap between the two chutes for the fasteners to pass through in a horizontal state. The far ends of the two linear grooves away from the vibrating bowls are respectively lapped on the two chutes. A support plate is provided at the bottom of the quenching chamber of the quenching furnace. One end of the support plate is hinged to the upper edge of the inner wall of the quenching chamber near the chute. An upwardly inclined baffle is installed at the end of the support plate away from the chute.

A top cover is provided above the floating block. A water storage chamber is installed on the lower surface of the top cover. The water storage chamber is fixedly connected to the quenching furnace through a connecting member. A rectangular hole is opened on the upper surface of the top cover. The rectangular rod passes through the rectangular hole. A bottom cover is installed at the bottom of the water storage chamber. A bottom box communicating with the water storage chamber is installed on the lower surface of the bottom cover. A rubber plate for squeezing moisture is slidably installed in the bottom box. An electric push rod arranged vertically is provided below the bottom box. The movable end of the electric push rod passes through the bottom box and is fixedly connected to the rubber plate. The cylinder end of the electric push rod is fixedly connected to the quenching furnace through a support. A bent pipe is installed on the upper surface of the top cover. One end of the bent pipe passes through the top cover and communicates with the internal space of the water storage chamber.

[0006] Specifically, the connecting member includes a connecting plate. Connecting plates are fixedly connected to two adjacent sides of the water storage chamber and the quenching furnace. A cushion strip is provided between the connecting plate and the quenching furnace. The cushion strip is fixedly connected to the quenching furnace. A plurality of uniformly arranged small holes are opened on the surface of the connecting plate facing the cushion strip. A plurality of screw holes aligned with the small holes are uniformly opened on the surface of the cushion strip facing the connecting plate. Screws are inserted into the small holes. One end of the screw is threadedly connected in the screw hole.

[0007] Specifically, a heat insulation plate is pasted on the lower surface of the rubber plate with glue. The movable end of the electric push rod is fixedly connected to the heat insulation plate. A vertical hole is opened at the bottom of the bottom box. The movable end of the electric push rod passes through the vertical hole.

[0008] Specifically, a through hole is opened at the middle position of the upper surface of the bottom cover. The through hole is arranged in the water storage chamber.

[0011] Advantages of the present invention:

[0012] 1. Place the fasteners in two vibrating bowls. When the vibrating bowls are working, the fasteners enter the straight groove one by one. Under the vibration of the vibrator, the fasteners in the straight groove move to the chute. Subsequently, the fasteners roll to the quenching cavity of the quenching furnace in a transverse state along the inclined chute, that is, the fasteners move to the pallet in a transverse state, so that the fasteners entering the quenching cavity do not overlap with each other, and the fasteners enter the quenching cavity in a rolling state, which is beneficial to heating different areas of the fasteners. Moreover, since the fasteners do not overlap with each other, the fasteners are heated evenly, which is beneficial to improving the quality of the fastener quenching.

[0013] 2. Blocked by the baffle, it prevents the fasteners in a rolling state from slipping off the pallet due to inertia, that is, the baffle and the chute together restrict the fasteners on the pallet. Control the electric push rod to contract, so that the electric push rod drives the rubber plate to move downward, causing the water in the water storage chamber to flow back into the bottom box. At this time, the floating block descends with the drop of the water level, and then the height of the supporting wheel drops, causing the baffle to change from an upward inclined state to a horizontal state. At this time, the end of the pallet away from the chute tilts downward, facilitating the removal of the heated fasteners. After controlling the electric push rod to extend, the pallet returns to the horizontal state, and the baffle returns to the upward inclined state.

[0014] 3. By making the water reciprocally transfer between the water storage chamber and the bottom box, and then changing the height of the supporting wheel under the action of buoyancy. On the one hand, the water, rubber plate, and heat insulation plate together play a role in blocking heat, preventing the heat on the baffle from transferring to the electric push rod and damaging the electric push rod. On the other hand, when the fasteners squeeze the structure formed by the pallet, baffle, etc., the position of the floating block in the water changes to achieve the purpose of buffering, making the rectangular rod and the rectangular hole cooperate with each other to prevent the supporting wheel from rotating. Install a bent pipe on the top cover. On the one hand, it is convenient to replenish water through the bent pipe. On the other hand, it is convenient to maintain the air pressure inside and outside the water storage chamber consistent.

[0015] 4. Align the small holes on the connecting plate with the screw holes on the cushion strip, and then pass the screws through the small holes and screw them into the screw holes to complete the assembly of the water storage chamber and the quenching furnace, achieving a local increase in the thickness of the part where the installation screws of the quenching furnace are located.

[0016] 5. Install a bottom box at the bottom of the water storage chamber, arrange the bottom box horizontally, and arrange the water storage chamber vertically, which is beneficial to reducing the height occupied by the structure formed by the bottom box and the water storage chamber.

[0025] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0026] Please refer to Figures 1 - 3, the present invention provides a technical solution: a fastener quenching device, including a quenching furnace 1. There is a seat frame 3 on one side of the quenching furnace 1. Two vibrating bowls 2 are installed on the upper surface of the seat frame 3. Linear grooves 22 are installed at the discharge ends of the two vibrating bowls 2. A vibrator 4 is installed at the bottom of the linear groove 22, and the vibrator 4 is installed on the surface of the quenching furnace 1. On the side of the linear groove 22 away from the vibrating bowl 2, there are two side plates 5. The two side plates 5 are symmetrically installed on the surface of the quenching furnace 1. Between the two side plates 5, two inclined chutes 27 are installed. The two chutes 27 are arranged in parallel and there is a gap between the two chutes 27 for the fasteners to pass through in a horizontal state. The two ends of the two linear grooves 22 away from the vibrating bowls 2 are respectively lapped on the two chutes 27. The fasteners are placed in the two vibrating bowls 2. When the vibrating bowls 2 work, the fasteners enter the linear grooves 22 one by one. Under the vibration of the vibrator 4, the fasteners in the linear grooves 22 move to the chutes 27. Subsequently, the fasteners roll down into the quenching cavity of the quenching furnace 1 in a horizontal state along the inclined chutes 27, that is, the fasteners move to the support plate 21 in a horizontal state. Thus, the fasteners entering the quenching cavity do not overlap with each other, and the fasteners enter the quenching cavity in a rolling state, which is beneficial to heating different areas of the fasteners, and the fasteners do not overlap with each other, making the fasteners heat evenly, which is beneficial to improving the quality of fastener quenching.

[0027] Refer to Figure 1 , Figure 2 and Figure 4 , at the bottom of the quenching cavity of the quenching furnace 1, there is a support plate 21. One end of the support plate 21 is hinged at the upper edge of the inner wall of the quenching cavity near the chute 27. At the end of the support plate 21 away from the chute 27, there is an upwardly inclined baffle 18. At both edges of the upper surface of the baffle 18, side plates 19 are fixedly connected. The side plates 19 and the baffle 18 are integrally formed structures. The baffle 18 and the support plate 21 are integrally formed structures. The design of the side plates 19 prevents the fasteners from falling from the side of the baffle 18. There is a support wheel 20 in contact with the baffle 18 under the baffle 18. There is an L-shaped seat 6 on one side of the support wheel 20. The support wheel 20 is rotatably connected to the L-shaped seat 6. A vertically arranged rectangular rod 16 is installed at the bottom of the horizontal part of the L-shaped seat 6. The support wheel 20 realizes the rolling contact between the rectangular rod 16 and the baffle 18.

[0028] Refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6, a floating block 23 is installed at the lower end of the rectangular rod 16. A positioning hole is formed by downward depression on the upper surface of the floating block 23, so that the lower end of the rectangular rod 16 is pasted in the positioning hole with glue, improving the connection stability between the rectangular rod 16 and the floating block 23. A top cover 15 is provided above the floating block 23. A water storage chamber 14 is installed on the lower surface of the top cover 15. A rectangular hole 26 is formed on the upper surface of the top cover 15. The rectangular rod 16 penetrates through the rectangular hole 26, enabling the rectangular rod 16 to cooperate with the rectangular hole 26 to prevent the supporting wheel 20 from rotating. A bottom cover 8 is installed at the bottom of the water storage chamber 14. A through port is formed at the middle position on the upper surface of the bottom cover 8, and the through port is arranged inside the water storage chamber 14. A bottom box 9 communicating with the water storage chamber 14 is installed on the lower surface of the bottom cover 8. A rubber plate 24 for squeezing water is slidably installed inside the bottom box 9. A vertical electric push rod 11 is provided below the bottom box 9. The movable end of the electric push rod 11 penetrates through a vertical hole formed at the bottom of the bottom box 9. An insulating board 25 is pasted on the lower surface of the rubber plate 24 with glue, and the movable end of the electric push rod 11 is fixedly connected to the insulating board 25. The cylinder end of the electric push rod 11 is fixedly connected to the quenching furnace 1 through a support 10. A bent pipe 17 is installed on the upper surface of the top cover 15. One end of the bent pipe 17 penetrates through the top cover 15 and communicates with the internal space of the water storage chamber 14. Blocked by the baffle 18, it prevents the fasteners in the rolling state from slipping off the support plate 21 under the action of inertia, that is, the baffle 18 and the chute 27 jointly restrict the fasteners on the support plate 21. Control the electric push rod 11 to contract, so that the electric push rod 11 drives the rubber plate 24 to move downward, causing the water in the water storage chamber 14 to flow back into the bottom box 9. At this time, the floating block 23 descends with the drop of the water level, and then the height of the supporting wheel 20 drops, causing the baffle 18 to change from the upward inclined state to the horizontal state. At this time, the end of the support plate 21 away from the chute 27 inclines downward, facilitating the removal of the heated fasteners. After controlling the electric push rod 11 to extend, the support plate 21 is restored to the horizontal state, and the baffle 18 is restored to the upward inclined state;

[0029] By reciprocally transferring water between the water storage chamber 14 and the bottom box 9, and then changing the height of the supporting wheel 20 under the action of buoyancy. On the one hand, the water, the rubber plate 24, and the insulating board 25 jointly play a role in blocking heat, preventing the heat on the baffle 18 from transferring to the electric push rod 11 and damaging the electric push rod 11. On the other hand, when the fasteners squeeze the structure formed by the support plate 21, the baffle 18, etc., the position of the floating block 23 in the water changes, achieving the purpose of buffering. Installing the bent pipe 17 on the top cover 15 is convenient for water replenishment operation through the bent pipe 17 on the one hand, and maintaining the air pressure inside and outside the water storage chamber 14 consistent on the other hand. Installing the bottom box 9 at the bottom of the water storage chamber 14, arranging the bottom box 9 horizontally, and arranging the water storage chamber 14 vertically are beneficial to reducing the height occupied by the structure formed by the bottom box 9 and the water storage chamber 14.

[0030] Refer to Figure 1 and Figure 4, on both sides of the water storage chamber 14 adjacent to the quenching furnace 1, connecting plates 13 are fixedly connected. There is a gasket strip 7 between the connecting plate 13 and the quenching furnace 1. The gasket strip 7 is fixedly connected to the quenching furnace 1. On the side of the connecting plate 13 facing the gasket strip 7, a plurality of uniformly arranged small holes are provided. On the side of the gasket strip 7 facing the connecting plate 13, a plurality of screw holes aligned with the small holes are uniformly provided. A screw 12 is inserted into the small hole, and one end of the screw 12 is threadedly connected into the screw hole, aligning the small hole on the connecting plate 13 with the screw hole on the gasket strip 7. Then, the screw 12 is passed through the small hole and screwed into the screw hole to complete the assembly of the water storage chamber 14 and the quenching furnace 1, realizing a local increase in the thickness of the part where the installation screw 12 of the quenching furnace 1 is located.
