Description

Technical Field

[0001] This utility model application relates to the field of processing furnace technology, specifically an ion nitriding oxidation composite processing furnace. Background Technology

[0002] Ion nitriding oxidation is performed in a low-vacuum furnace filled with nitrogen-containing gas, with the metal workpiece as the cathode and the furnace as the anode. When electricity is applied, nitrogen and hydrogen atoms in the medium are ionized under a high-voltage DC electric field, forming a plasma region between the cathode and anode. Under the influence of the strong electric field in the plasma region, nitrogen and hydrogen ions bombard the workpiece surface at high speed. The high kinetic energy of the ions is converted into heat energy, heating the workpiece surface to the required temperature. Due to the bombardment of ions, atomic sputtering occurs on the workpiece surface, thus achieving purification. At the same time, due to adsorption and diffusion, nitrogen penetrates into the workpiece surface. It is widely used in many fields such as automobiles, machinery, precision instruments, extrusion molding machines, and molds.

[0003] When using a pit-type nitriding furnace, the workpiece needs to be placed into the furnace body through the furnace top. However, due to the height of the existing processing furnace, it is very inconvenient to place and remove the workpiece. As a result, the processing furnace requires a lot of auxiliary tools when in use, which increases the difficulty of operation. Summary of the Invention

[0004] To address the inconvenience of loading and unloading workpieces in existing ion nitriding and oxidation composite treatment furnaces, this invention provides an ion nitriding and oxidation composite treatment furnace to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An ion nitriding oxidation composite treatment furnace includes a furnace body and a furnace cover. The furnace cover is provided on the top surface of the furnace body, and a lifting frame is provided on the side of the furnace body. A servo motor is provided on the top surface of the lifting frame. A lead screw is rotatably connected to the inside of the lifting frame through a bearing. A movable sleeve is threaded on the lead screw. One end of the movable sleeve extending to the outside of the lifting frame is fixed. The output end of the servo motor rotatably passes through the lifting frame and is fixed to the top of the lead screw. The bottom surface of the side of the furnace cover is rotatably connected to the top of the movable sleeve through a bearing. A second servo motor is provided at the bottom of the movable sleeve. The output end of the second servo motor rotatably passes through the movable sleeve and is fixed to the bottom surface of the furnace cover.

[0007] Furthermore, a connecting sleeve is rotatably connected to the bottom of the furnace cover via a bearing, a placement rack is fixed to the bottom of the connecting sleeve, and a sealing gasket is glued to the bottom surface of the furnace cover on the outside of the connecting sleeve.

[0008] Furthermore, the bottom of the placement rack is provided with a movable groove, and a support plate is rotatably sleeved inside the movable groove. A support rod is fixed at the center of the top surface of the support plate, and a crank handle is fixed at one end of the support rod that rotatably passes through the top of the furnace cover.

[0009] Furthermore, a sealing sleeve is fixed inside the connecting sleeve on the outer side of the support rod, and the inner wall of the sealing sleeve slides against the outer surface of the support rod. The thickness of the support plate is less than the thickness of the movable groove.

[0010] Furthermore, a fixed connecting plate is fixedly sleeved on the support connecting rod at the bottom of the crank handle, and a fixed sleeve is threaded on the outer side of the fixed connecting plate. The bottom surface of the fixed sleeve is rotatably connected to the top surface of the furnace cover through a bearing.

[0011] Furthermore, the outer surface of the fixed connecting plate is provided with a thread that mates with the fixed sleeve, the height of the fixed sleeve is equal to the height of the fixed connecting plate, and the diameter of the fixed sleeve is smaller than the diameter of the crank handle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the liftable and rotatable furnace cover allows the placement rack to be pulled out and rotated to be misaligned with the furnace body when placing workpieces. After misalignment, it can be lowered to a height that is convenient for operation, making it easy to pick up and put down workpieces. This solves the problem of inconvenient workpiece loading and unloading operations in existing ion nitriding and oxidation composite treatment furnaces and improves the convenience of using the treatment furnace.

[0014] 2. In this utility model, the internal rotatable sliding tray allows the workpiece to be lifted during use, so that the bottom of the workpiece can be fully exposed. Moreover, during operation, there is no need to open the furnace cover, thus ensuring the sealing of the furnace body. Attached Figure Description

Detailed Implementation

[0020] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Reference Figure 1 , Figure 2 and Figure 3 An ion nitriding oxidation composite treatment furnace includes a furnace body 1 and a furnace cover 2. The furnace cover 2 is provided on the top surface of the furnace body 1, and a lifting frame 3 is provided on the side of the furnace body 1. A servo motor 4 is provided on the top surface of the lifting frame 3. A lead screw is rotatably connected to the inside of the lifting frame 3 through a bearing. A movable sleeve block is threaded on the lead screw. A movable sleeve block 5 is fixed at one end of the movable sleeve block extending to the outside of the lifting frame 3. The output end of the servo motor 4 rotatably passes through the lifting frame 3 and is fixed to the top of the lead screw. The bottom surface of the side of the furnace cover 2 is rotatably connected to the top of the movable sleeve block 5 through a bearing. A servo motor 6 is provided at the bottom of the movable sleeve block 5. The output end of the servo motor 6 rotatably passes through the movable sleeve block 5 and is fixed to the bottom surface of the furnace cover 2. A connecting sleeve 10 is rotatably connected to the bottom of the furnace cover 2 through a bearing. A placement rack 9 is fixed to the bottom of the connecting sleeve 10. A sealing gasket 7 is glued to the bottom surface of the furnace cover 2 outside the connecting sleeve 10.

[0022] Specifically, when a workpiece needs to be placed, servo motor 4 drives the internal screw of the lifting frame 3 to rotate. When rotating, it drives the furnace cover 2 to move upward. After moving upward, it drives the placement frame 9 to move out of the furnace body 1. After moving out, servo motor 6 drives the furnace cover 2 to rotate, so that the furnace cover 2 rotates away from the furnace body 1 until the placement frame 9 is completely misaligned with the furnace body 1. At this time, servo motor 4 drives the screw to rotate in the opposite direction, thereby driving the placement frame 9 to move downward and place the workpiece on the placement frame 9. servo motor 4 drives the placement frame 9 to move upward to the top of the furnace body 1. servo motor 6 drives the furnace cover 2 to rotate and align with the placement frame 9. servo motor 4 then drives the placement frame 9 to move downward until the furnace cover 2 closes on the top surface of the furnace body 1.

[0023] As an optimized solution, the bottom of the placement rack 9 is provided with a movable groove 16, and a support plate 15 is rotatably sleeved inside the movable groove 16. A support rod 8 is fixed at the center of the top surface of the support plate 15. A sealing sleeve 14 is fixed inside the connecting sleeve 10 on the outside of the support rod 8. The outer surface of the fixed connecting plate 12 is provided with threads that mate with the fixed sleeve 13. The height of the fixed sleeve 13 is equal to the height of the fixed connecting plate 12. The diameter of the fixed sleeve 13 is smaller than the diameter of the crank handle 11. The inner wall of the sealing sleeve 14 slides and fits against the outer surface of the support rod 8. The thickness of the support plate 15 is smaller than the thickness of the movable groove 16. The crank handle 11 is fixed at one end of the support rod 8 that rotatably passes through the top of the furnace cover 2. The fixed connecting plate 12 is fixedly sleeved on the support rod 8 at the bottom of the crank handle 11. The fixed sleeve 13 is threaded on the outside of the fixed connecting plate 12. The bottom surface of the fixed sleeve 13 is rotatably connected to the top surface of the furnace cover 2 through a bearing.

[0024] Specifically, when it is necessary to expose the bottom of the workpiece, turn the crank handle 11, which drives the support rod 8 to rotate the pallet 15 inside the movable groove 16. When rotating, the pallet 15 rotates inside the movable groove 16. After the fixed connecting plate 12 separates from the fixed sleeve 13, pull the crank handle 11 to lift the bottom of the workpiece, thus exposing the bottom of the workpiece. After exposure, pull the support rod 8 downward to make the workpiece fall back onto the placement frame 9. Then, rotate the support rod 8 to rotate the pallet 15 to a position that is offset from the position where the bottom of the workpiece was lifted last time. Then, pull the support rod 8 upward to lift the workpiece. In this way, the bottom of the workpiece is completely exposed.
