Description

Technical Field

[0001] The present application relates to the field of fastener processing, and particularly relates to a continuous heat treatment device for fasteners. Background Art

[0002] A fastener is a mechanical part used to connect, fix, or combine two or more components. Common fasteners include screws, bolts, nuts, washers, etc. In order to enhance the overall strength and durability of fasteners, continuous heat treatment is carried out on them. Through a series of continuous processes such as heating, quenching, and tempering, the mechanical properties, wear resistance, and corrosion resistance of fasteners are improved.

[0003] When a fastener is quenched, it is quickly immersed in a cooling medium (oil or water). However, water droplets may appear on the surface of the fastener after quenching. And the fastener will also be tempered after quenching. If the moisture is not removed before tempering, it may cause surface oxidation or corrosion. Therefore, the quenched fasteners are generally dried. However, the existing fasteners consume a long time during drying, and some fasteners stacked together may not be dried sufficiently, which will affect the overall drying effect of the fasteners, causing certain damage to the fasteners during subsequent processing and having a certain impact on the continuous heat treatment efficiency of the fasteners.

[0004] In view of the above related technologies, the inventor believes that there is a defect that the drying time of the quenched fasteners is relatively long when the fasteners are heat-treated. Therefore, a continuous heat treatment device for fasteners is proposed to solve the above problems. Utility Model Content

[0005] In order to solve the problem that the drying time of the quenched fasteners is relatively long when the fasteners are heat-treated, the present application provides a continuous heat treatment device for fasteners.

[0006] The continuous heat treatment device for fasteners provided by the present application adopts the following technical solutions:

[0007] A continuous heat treatment device for fasteners includes a drying treatment box. On both sides of the outer surface of the drying treatment box, a first rotating shaft is rotatably installed. One end of a single first rotating shaft extends to the outside of the drying treatment box and is installed with a driving motor. On the outer surface of the first rotating shaft, a conveyor belt is symmetrically sleeved on the side edges. On the upper surface of the conveyor belt, a placement box is placed. A plurality of water filtering holes are penetrated and opened at the bottom end of the inner wall of the placement box. A water draining port is opened in the middle of the bottom end of the inner wall of the drying treatment box. On the front and rear ends of the inner wall of the drying treatment box, close to the lower side of the placement box, a second rotating shaft is rotatably installed. One end of the second rotating shaft extends to the outside of the drying treatment box and is installed with a servo motor. A cam is welded on the outer surface of the second rotating shaft close to the inner side of the conveyor belt. A drying mechanism is further provided on the upper surface of the drying treatment box for cleaning the water droplets on the surface of the fasteners in the placement box.

[0008] Preferably, the drying mechanism includes a ventilation opening which is arranged in the middle of the inner wall at the top of the drying box. A fixing bracket is fixedly installed on the upper surface of the drying box near the outside of the ventilation opening. An electric heating tube is fixedly installed at the inner bottom of the fixing bracket near the ventilation opening. A motor is installed in the middle of the top of the fixing bracket. The output end of the lower bottom surface of the motor extends into the fixing bracket and is equipped with a fan.

[0009] Preferably, fixing brackets are symmetrically welded to the front and rear ends of the inner wall of the drying box near the placement box. An extension plate is fixedly installed on the upper surface of the placement box. The upper surface of the fixing bracket fits with the lower bottom surface of the extension plate.

[0010] Preferably, a feed inlet is penetratingly opened in the middle of one side of the drying box. One side of the outer surface of the conveyor belt is located inside the drying box. The upper surface of the conveyor belt extends into the feed inlet. The cross-sectional area of one side of the placement box is smaller than that of one side of the feed inlet. The placement box and the feed inlet are mutually adapted.

[0011] Preferably, the volume of the fan is smaller than the inner volume of the fixing bracket. The fan is located above the electric heating tube. The fixing bracket and the fan are mutually fitted.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] By placing the fasteners in the placement box, they are conveyed along the upper surface of the conveyor belt to the middle position inside the drying box. At the same time, the rotating second rotating shaft drives the cam to act on the lower bottom surface of the placement box, vibrating the fasteners in the placement box to make the water droplets on their surfaces drip off, and the fan cooperates with the electric heating tube to blow hot air into the drying box. Compared with the prior art, this solution has the effect of facilitating the drying treatment of the fasteners, improving the overall drying rate of the fasteners, solving the problem that the drying of the fasteners takes a long time, and reflecting the vibrating turning effect of the fasteners.

Detailed implementation manners

[0018] The following further elaborates on this application Figures 1-3 in conjunction with the attached drawings.

[0019] An embodiment of this application discloses a continuous heat treatment device for fasteners. Refer to Figures 1-3 Figure [not provided in the original, so it remains in Chinese for now], a continuous heat treatment device for fasteners includes a drying treatment box 1. On both sides of the outer surface of the drying treatment box 1, a first rotating shaft 2 is rotatably installed. One end of a single first rotating shaft 2 extends outside the drying treatment box 1 and is installed with a driving motor 3. Symmetrically sleeved on the outer surface edge of the first rotating shaft 2 are conveyor belts 4. On the upper surface of the conveyor belts 4, placement boxes 5 are placed. In the middle of one side of the drying treatment box 1, a feed inlet is penetrated and opened. One side of the outer surface of the conveyor belt 4 is inside the drying treatment box 1, and the upper surface of the conveyor belt 4 extends into the feed inlet. The cross-sectional area of one side of the placement box 5 is smaller than the cross-sectional area of one side of the feed inlet, and the placement box 5 and the feed inlet are mutually adapted. A number of water filtering holes 6 are penetrated and opened at the bottom end of the inner wall of the placement box 5. A water draining opening is opened in the middle of the bottom end of the inner wall of the drying treatment box 1. At the front and rear ends of the inner wall of the drying treatment box 1 near the lower part of the placement box 5, a second rotating shaft 7 is rotatably installed. One end of the second rotating shaft 7 extends outside the drying treatment box 1 and is installed with a servo motor 8. A cam 9 is welded on the outer surface of the second rotating shaft 7 near the inner side of the conveyor belt 4. A drying mechanism is further provided on the upper surface of the drying treatment box 1 for cleaning the water droplets on the surface of the fasteners in the placement box 5.

[0020] By placing the fasteners in the placement box 5, starting the driving motor 3 to drive the first rotating shaft 2 and the conveyor belt 4 to move, placing the placement box 5 on the upper surface of the conveyor belt 4, so that the fasteners are conveyed along the upper surface of the conveyor belt 4 to the middle position inside the drying treatment box 1. At the same time, starting the servo motor 8 to drive the second rotating shaft 7 to rotate, so that the rotating second rotating shaft 7 drives the cam 9 to rotate synchronously, and the rotating cam 9 acts on the lower bottom surface of the placement box 5, thereby driving the placement box 5 and the fasteners inside it to vibrate up and down, so that the water droplets on the fasteners drip and filter downward through the water filtering holes 6 from the water draining holes in the drying treatment box 1, reflecting the effect of the fasteners vibrating up and down to shake off and drain the surface water droplets.

[0021] Refer to Figure 1 and Figure 3, the drying mechanism includes a ventilation opening 11 which is opened at the middle of the inner wall top of the drying treatment box 1. At the outer part of the ventilation opening 11 on the upper surface of the drying treatment box 1, a fixed bracket 12 is fixedly installed. At the inner bottom of the fixed bracket 12 near the ventilation opening 11, an electric heating tube 13 is fixedly installed. At the middle of the top of the fixed bracket 12, a motor 14 is installed. The output end of the lower bottom surface of the motor 14 extends into the fixed bracket 12 and is installed with a fan 15. The volume of the fan 15 is smaller than the inner volume of the fixed bracket 12. The fan 15 is above the electric heating tube 13, and the fixed bracket 12 and the fan 15 are mutually fitted.

[0022] By starting the motor 14 to drive the fan 15 to rotate and starting the electric heating tube 13 to heat the internal environment of the fixed bracket 12, the fan 15 blows the external fresh air into the fasteners in the drying treatment box 1 along the ventilation opening 11, and the electric heating tube 13 heats the fresh air into hot air, so that the hot air quickly evaporates the water droplets attached to the surface of the fasteners, reflecting the evaporation treatment effect of the fan 15 cooperating with the electric heating tube 13 on the water droplets on the surface of the fasteners.

[0023] Refer to Figure 2 and Figure 3 , at the front and rear ends of the inner wall of the drying treatment box 1 near the placement box 5, fixed connecting plates 10 are symmetrically welded. On the upper surface of the placement box 5, an extension plate is fixedly installed. The upper surface of the fixed connecting plate 10 is mutually attached to the lower bottom surface of the extension plate. By moving the placement box 5 to drive the extension plate above the fixed connecting plate 10, the placement box 5 vibrates up and down along the inside of the drying treatment box 1, and the fixed connecting plate 10 resists the downwardly moving placement box 5 to prevent the placement box 5 from driving the conveyor belt 4 to move significantly due to a large downward impact force. The placement box 5 can move stably on the conveyor belt 4, reflecting the supporting effect of the fixed connecting plate 10 on the placement box 5.

[0024] The implementation principle of a continuous heat treatment device for fasteners in an embodiment of this application is as follows: Place the fasteners in the placement box 5, start the drive motor 3 to drive the first rotating shaft 2 and the conveyor belt 4 to move, place the placement box 5 on the upper surface of the conveyor belt 4, and convey the fasteners along the upper surface of the conveyor belt 4 to the middle position inside the drying treatment box 1. At the same time, start the servo motor 8 to drive the second rotating shaft 7 to rotate, so that the rotating second rotating shaft 7 drives the cam 9 to rotate synchronously, and the rotating cam 9 acts on the lower bottom surface of the placement box 5, thereby driving the placement box 5 and the fasteners inside it to vibrate up and down, causing the water droplets on the fasteners to drip and filter downward through the water filtering holes 6 from the drain holes in the drying treatment box 1. And start the motor 14 to drive the fan 15 to rotate, start the electric heating tube 13 to heat the internal environment of the fixed bracket 12, so that the fan 15 blows the external fresh air onto the fasteners in the drying treatment box 1 along the ventilation port 11, and the electric heating tube 13 heats the fresh air into hot air, so that the hot air quickly evaporates the water droplets attached to the surface of the fasteners. The power input ends of the drive motor 3, the servo motor 8, the electric heating tube 13, and the motor 14 are electrically connected to the output end of the external power supply; compared with the prior art, this solution has the effect of facilitating the drying treatment of fasteners, improving the overall drying rate of fasteners, solving the problem of long drying time for fasteners, and reflecting the vibration and turning effect of fasteners.
