[0001] This invention relates to the field of fastener processing technology, and in particular to a fastener heat treatment feeding device. Background Technology

[0002] Automotive fasteners are a type of automotive mechanical parts used for fastening connections and have extremely wide applications. Heat treatment is a process that changes the internal structure of steel in the solid state through heating and cooling, thereby obtaining the desired properties. It is an important process in the manufacturing of machine parts and tools, and it is of great significance for realizing the potential of metal materials, improving the performance of parts, improving product quality, and extending service life.

[0009] As a preferred embodiment of the present invention, a vertical cleaning chamber is provided at one end of the feeding shell. A rotating component is fixedly installed in the cleaning chamber to drive the fasteners to be fed slowly. A spray pipe is fixedly installed on the cleaning chamber, and multiple nozzles are provided on the spray pipe for cleaning the fasteners. A water pipe is connected to the spray pipe.

[0010] As a preferred embodiment of the present invention, the rotating assembly includes a shaft frame, which is fixedly connected to the inner wall of the cleaning chamber.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Example 1: This example discloses a fastener heat treatment feeding device, such as... Figures 1-8As shown, the device includes a base frame 1, a mesh belt furnace 102, a mesh belt conveyor 101, and a feeding mechanism 3 for feeding materials to the mesh belt conveyor 101. The mesh belt furnace 102 and the feeding mechanism 3 are fixedly installed above the base frame 1. The feeding mechanism 3 is located above the feeding end of the mesh belt conveyor 101. A vibration motor 7 is installed on the lower surface of the feeding mechanism 3 to drive the feeding mechanism 3 to vibrate, which facilitates feeding. The feeding mechanism 3 includes a hopper 4, a material rack 401 that is inclined and fixedly installed above the hopper 4, a guide component 5 that is fixedly installed in the material rack 401, and a discharge component 6 that is installed below the material rack 401. The material rack 401 and the guide component 5 are both inclined downwards. The fasteners in the hopper 4 are conveyed to the discharge component 6 through the guide component 5, and finally evenly and neatly conveyed to the mesh belt conveyor 101.

[0028] like Figure 3 As shown, a baffle 402 is fixedly connected inside the hopper 4, and the baffle 402 contacts the inner wall of the hopper 4. A lifting cylinder 404 is installed below the hopper 4, and a top plate 403 is fixedly installed on the lifting cylinder 404. The top plate 403 is movably connected to the hopper 4, and the top plate 403 penetrates through the bottom surface of the hopper 4. The top plate 403 is in contact with the surface of the baffle 402, and the bottom surface of the hopper 4 is inclined. A pushing cylinder 405 is fixedly installed at the upper end of the baffle 402, and a pushing plate 406 is connected to the pushing cylinder 405. It is used to push the fasteners on the top plate 403 onto the guide assembly 5; the lifting cylinder 404 drives the top plate 403 to rise to the same height as the upper end of the guide assembly 5, and then the pushing cylinder 405 drives the pushing plate 406 to move, pushing the fasteners on the top plate 403 onto the guide assembly 5. When the top plate 403 rises to the highest point, the lower end of the top plate 403 is still outside the hopper 4, and when the top plate 403 falls to the lowest point, the upper end of the top plate 403 is still inside the hopper 4.

[0029] like Figure 4As shown, the material guiding assembly 5 includes multiple downwardly inclined material guiding tracks 503. Each material guiding track 503 has a strip-shaped material guiding hole 504 along its length. The width of the material guiding hole 504 is slightly larger than the diameter of the fastener rod but smaller than the diameter of the fastener head, allowing the fastener rod to be inserted into the material guiding hole 504 without falling out. The material guiding assembly 5 also includes a receiving plate 501, located at the upper end of each material guiding track 503. The receiving plate 501 has a corresponding material guiding groove 502 fixedly connected to it, with each groove being V-shaped. The grooves are connected to the upper end of the material guiding tracks 503, and the ends of the material guiding holes 504 are provided with... The discharge hole 505 corresponding to the discharge shell 601 has a diameter larger than that of the fastener head. After passing through the discharge hole 505, the fastener falls directly into the discharge shell 601. The pusher cylinder 405 pushes the fastener onto the receiving plate 501, and then the fastener slides down onto the guide rail 503 through the guide groove 502. Among them, the fastener with the head facing upward can slide into the guide hole 504. Under the vibration of the vibrating motor 7, it slides down along the guide hole 504 and finally enters the discharge assembly 6 through the discharge hole 505, and is finally conveyed to the mesh belt conveyor 101. The fastener with the head facing downward cannot slide into the guide hole 504 and falls back into the hopper 4 through the gap between the adjacent guide rails 503.

[0030] like Figure 5 - Figure 6 As shown, the feeding assembly 6 includes a feeding shell 601 that corresponds one-to-one with the guide rail 503. The feeding shell 601 is fixedly installed below the material rack 401. The fasteners fall directly into the feeding shell 601 through the guide rail 503 and are finally conveyed to the mesh belt conveyor 101 through the feeding shell 601.

[0031] In practice: the lifting cylinder 404 raises the top plate 403 to a position level with the upper end of the guide assembly 5. Then, the pushing cylinder 405 moves the pushing plate 406, pushing the fasteners on the top plate 403 onto the receiving plate 501. Through the reciprocating lifting and lowering of the top plate 403, the fasteners are continuously conveyed to the guide assembly 5. The fasteners slide down the guide groove 502 onto the guide rail 503, and some fasteners can slide into the guide hole 504 and be discharged through the guide hole 504. Finally, the fasteners enter the discharge shell 601 through the discharge hole 505 and are eventually conveyed to the mesh belt conveyor 101. Another part of the fasteners cannot slide into the guide hole 504 and fall back into the hopper 4 through the gap between the adjacent guide rails 503. In this embodiment, through the cooperation of the lifting cylinder 404, the guide component 5 and the discharge component 6, the fasteners can be evenly and neatly conveyed to the mesh belt conveyor 101, avoiding the accumulation of fasteners and ensuring that the heat treatment quality of the same batch of fasteners is the same.

[0032] Example 2: Based on the structure of Example 1 above, as follows Figure 1 and Figures 5-8 As shown, in this embodiment, a vertical cleaning chamber 6012 is provided at the feeding end of the feeding shell 601. A rotating assembly 603 is fixedly installed inside the cleaning chamber 6012. The rotating assembly 603 can slow down the falling speed of the fasteners. A spray pipe 602 is fixedly installed on the cleaning chamber 6012. The spray pipe 602 is provided with multiple nozzles 6021 for cleaning the fasteners. A water pipe 6022 is connected to the spray pipe 602 and is connected to an external water pump. Several water outlet holes 6014 are provided on the surface of the feeding shell 601. The water outlet holes 6014 are arranged vertically on the surface of the feeding shell 601. A water tank 2 is provided below the feeding assembly 6 and is installed on the base frame 1. The sprayed water flows into the water tank 2 through the water outlet 6014. The water in the water tank 2 can be recycled after treatment. The fastener falls into the feed shell 601 and enters the rotating component 603 in the cleaning chamber 6012. The rotating component 603 drives the fastener to fall slowly. At the same time, the spray pipe 602 sprays cleaning agent to clean the surface of the fastener and remove dust and dirt. Furthermore, the spray pipe 602 is not directed towards the center vertical line of the fastener, but towards a position slightly off the center line. This allows the spray pipe 602 to drive the fastener to rotate when spraying water, continuously adjusting the position of the fastener and thus cleaning the entire circumference of the fastener.

[0033] like Figure 8 As shown, the rotating assembly 603 in this embodiment includes a shaft bracket 6031, which is fixedly connected to the inner wall of the cleaning chamber 6012. A feed pipe 6032 is rotatably connected to the shaft bracket 6031. The inner diameter of the feed pipe 6032 is larger than the size of the fastener head. A spiral guide plate 6034 is fixedly connected to the feed pipe 6032, forming a vertical discharge hole 6035. The diameter of the discharge hole 6035 is larger than the diameter of the fastener rod but smaller than the fastener head. The diameter of the head allows the spiral guide plate 6034 to support the head of the fastener. The fastener is conveyed into the feed pipe 6032 through the drop hole 6035. A water turbine blade 6033 is fixedly installed on the feed pipe 6032. Water sprayed from one of the nozzles 6021 on the spray pipe 602 can drive the water turbine blade 6033 to rotate, which in turn drives the feed pipe 6032 and the spiral guide plate 6034 to rotate. When the spiral guide plate 6034 rotates, it causes the fastener to fall slowly.

[0034] Preferably, a guide seat 6011 is fixedly connected to one end of the feed shell 601. The guide seat 6011 is provided with a V-shaped groove to guide the fastener into the discharge hole 6035.

[0035] Preferably, the discharge end of the feeding shell 601 is provided with a drying chamber 6013. The drying chamber 6013 is connected to an air supply duct 604 through a connecting pipe 605. The air supply duct 604 is provided with an interface 606, which is connected to a fan through a pipe. The fan delivers hot air to the drying chamber 6013. The fasteners above the drying chamber 6013 push the fasteners below to be discharged. The fasteners pass through the drying chamber 6013 in 2-3 seconds. The hot air temperature is controlled between 250-300°C, which can quickly dry the fasteners.

[0036] In practice: the fasteners fall into the discharge hole 6035 through the guide seat 6011, while the spray pipe 602 sprays high-pressure water. One of the nozzles 6021 sprays water to drive the water wheel blades 6033 to rotate slowly, which in turn drives the discharge pipe 6032 and the spiral guide plate 6034 to rotate. When the spiral guide plate 6034 rotates, it drives the fasteners to fall slowly. The spray pipe 602 cleans the surface of the fasteners to remove dust and dirt, thereby improving the quality of the fasteners after heat treatment. The cleaned water flows into the water tank 2. After cleaning, the fasteners are dried when they pass through the drying chamber 6013 and are finally conveyed to the mesh belt conveyor 101 to enter the mesh belt furnace for heat treatment.
