Description

Technical Field

[0001] This utility model belongs to the technical field of stamping die processing equipment, specifically relating to an ion nitriding treatment device for stamping dies. Background Technology

[0002] The main equipment for ion nitriding treatment of stamping dies is the ion nitriding furnace, which uses glow discharge to ionize nitrogen-containing gas, and the generated nitrogen ions bombard the die surface to achieve nitriding treatment, which can improve the surface hardness, wear resistance and other properties of the die.

[0003] For example, in Chinese utility model publication CN211645368U, entitled "An Ion Nitriding Treatment Device for Cold Stamping Dies," the device specifically includes a main body. The main body consists of a nitriding chamber and a movable chamber. The movable chamber has side baffles on its surface, and its top is connected to a sealing cover via a top fixing plate. The nitriding chamber has an insulating outer shell on its surface, and a catalyst layer inside. The aforementioned prior art uses a rotatable base to treat the die in a 360-degree surround manner, ensuring uniform overall processing results. However, when nitriding stamping dies, since there are many dies to be treated, it is not convenient to nitrid multiple dies simultaneously, which hinders the improvement of nitriding effect and efficiency. Therefore, an ion nitriding treatment device for stamping dies is needed. Utility Model Content

[0004] The purpose of this invention is to provide a simple and reasonably designed ion nitriding treatment device for stamping dies in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An ion nitriding treatment device for stamping dies includes a base, an outer shell fixedly mounted on the upper side of the base, a nitrogen inlet pipe fixedly connected to one side of the outer shell, a nitrogen outlet pipe fixedly connected to the other side of the outer shell, a catalyst layer fixedly mounted inside the outer shell, and a feeding and discharging mechanism for picking up and placing dies mounted on the outer shell, with a rotating mechanism for driving the dies to rotate inside the feeding and discharging mechanism.

[0007] As a further optimization of this utility model, the rotating mechanism includes multiple mesh boxes rotatably disposed inside the feeding and discharging mechanism. A first connecting rod is fixedly disposed between the multiple mesh boxes. A square groove is opened on the lower side of the first connecting rod. A servo motor for driving the first connecting rod to rotate is fixedly disposed on the lower side of the base. A reducer is fixedly disposed on the output shaft of the servo motor. A second connecting rod that rotatably passes through the base and the outer shell is fixedly disposed at the output end of the reducer. A square locking block that engages with the square groove is fixedly disposed on the upper side of the second connecting rod.

[0008] As a further optimization of this utility model, the feeding and discharging mechanism includes electric telescopic rods fixed on both sides of the outer shell. The output ends of the two electric telescopic rods are fixedly provided with top plates that fit against the upper side of the outer shell. A sealing ring is fixedly provided on the lower side of the top plate. A slot is opened on the upper side of the outer shell to engage with the sealing ring. A fixing frame located inside the sealing ring is fixedly provided on the lower side of the top plate. All of the above rotate within the fixing frame.

[0009] As a further optimization of this utility model, the servo motor and reducer are fixed to the lower side of the base by a plate, and the lower side of the first connecting rod rotatably passes through the bottom of the fixing frame and is connected to the square card block.

[0010] As a further optimization of this utility model, the outer sides of the multiple mesh boxes are all in contact with the inner side of the fixing frame, and multiple rods that are in contact with the lower side of the mesh boxes are fixed at equal angles on the lower side of the fixing frame.

[0011] As a further optimization of this utility model, a switch valve is fixedly installed on both the nitrogen inlet pipe and the nitrogen outlet pipe, and a ladder is fixedly installed on one side of the outer shell.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting a rotating mechanism, has a grid structure on the bottom and sides of the grid box. After the stamping die is placed on the grid box, the stamping die can be ion nitrided in all directions during the ion nitriding treatment. The grid box has multiple layers, and each layer is fixedly connected by a first connecting rod. The square locking block engages with the square slot opened on the bottom surface of the bottom grid box. When the fixing frame moves the grid box upward, the grid box can disengage from the square locking block, which facilitates the improvement of the effect and efficiency of the ion nitriding treatment.

[0014] 2. This utility model features a feeding and discharging mechanism with electric telescopic rods fixed on both sides of the base. The output end of the electric telescopic rods drives the top plate to move up and down on the base. The top plate moves up and down along with the fixed frame that holds the stamping die. After the fixed frame drives the rotating mechanism to the top, the stamping die is removed and placed. When the top plate moves down with the fixed frame, the sealing ring engages with the slot on the outer shell, sealing the connection between the top plate and the outer shell. This facilitates the removal of the material-holding structure along with the material from the outer shell, making it easy to pick up and place the material. Attached Figure Description

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a stamping die ion nitriding treatment device includes a base 1, an outer shell 2 fixedly mounted on the upper side of the base 1, a nitrogen inlet pipe 3 fixedly connected to one side of the outer shell 2, a switch valve 4 fixedly mounted on the nitrogen inlet pipe 3, and a nitrogen outlet pipe 5 fixedly connected to the other side of the outer shell 2, also fixedly mounted on the nitrogen outlet pipe 5 with a switch valve 4. The nitrogen inlet pipe 3 is the nitrogen inlet pipe, and the nitrogen outlet pipe 5 is the nitrogen outlet pipe. The nitrogen inlet and outlet are controlled by the switch valve 4. A ladder 6 is fixedly mounted on one side of the outer shell 2. Since the stamping die ion nitriding treatment device is a large piece of equipment, the operator needs to go to the upper side of the device to operate it. Therefore, a ladder 6 is set on one side of the outer shell 2 to facilitate the operator to go to the upper side of the outer shell 2. A catalyst layer 7 is fixedly mounted inside the outer shell 2. After the nitrogen enters the interior of the outer shell 2, it is first catalyzed by the catalyst layer 7 to accelerate the reaction efficiency.

[0026] like Figure 1 , Figure 2 , Figure 5 As shown, the outer casing 2 is equipped with a material feeding / discharging mechanism 8 for picking up and placing materials. The material feeding / discharging mechanism 8 includes an electric telescopic rod 801. Electric telescopic rods 801 are fixed on both sides of the outer casing 2. A top plate 802 is fixedly installed at the output end of each of the two electric telescopic rods 801. The lower side of the top plate 802 is in contact with the upper side of the outer casing 2. A sealing ring 803 is fixedly installed on the lower side of the top plate 802. A slot 804 is provided on the upper side of the outer casing 2. The sealing ring 803 engages with the slot 804. The output end of the electric telescopic rod 801 drives the top plate 802 to move up and down. When the top plate 802 moves upward, the sealing ring 803 disengages from the slot 804. When the top plate 802 moves downward, the sealing ring 803 engages with the slot 804. The connection between the outer shell 2 and the top plate 802 is sealed to prevent nitrogen from leaking from the connection between the outer shell 2 and the top plate 802 during ion nitriding treatment. A fixing frame 805 is fixedly installed on the lower side of the top plate 802. The fixing frame 805 is located inside the sealing ring 803. A square hole through which a square locking block 907 slides is opened on the lower side of the fixing frame 805. Multiple rods that fit against the lower side of the grid box 901 are fixed at equal angles on the lower side of the fixing frame 805. When the top plate 802 moves upward with the fixing frame 805 and moves out of the outer shell 2, the operator can place a stamping mold on the grid box 901 inside the fixing frame 805. After the stamping mold is placed, the fixing frame 805 is moved downward into the outer shell 2.

[0027] like Figure 6 , Figure 7As shown, a rotating mechanism 9 is provided inside the fixed frame 805. The rotating mechanism 9 includes a grid box 901. Multiple grid boxes 901 are rotatably arranged inside the fixed frame 805. The sides and bottom of the grid boxes 901 are grid structures, which allows the bottom surface of the stamping die to also be ion nitrided. The outer side of each grid box 901 is in contact with the inner side of the fixed frame 805. Multiple grid boxes 901 are fixedly arranged with a first connecting rod 902. By setting multiple grid boxes 901, more stamping dies can be placed, and more stamping dies can be ion nitrided at one time. A square groove 903 is opened on the lower side of the first connecting rod 902 at the bottom. A servo motor 904 is arranged on the lower side of the grid box 901. A reducer 905 is fixedly arranged on the output shaft of the servo motor 904. Plates are fixedly arranged on the servo motor 904 and the reducer 905, and the two are fixed by the plates. On the lower side of the base 1, a second connecting rod 906 is fixedly installed at the output end of the reducer 905. The second connecting rod 906 is rotatably installed inside the outer shell 2. A square locking block 907 is fixedly installed on the upper side of the second connecting rod 906. The square locking block 907 engages with the square slot 903. Since the fixing frame 805 can move the mesh box 901 up and down, the mesh box 901 needs to be separated from the second connecting rod 906 during movement. Therefore, the square slot 903 and the square locking block 907 are provided. The square structure allows the two to engage. When connected in this way, the servo motor 904 can rotate the first connecting rod 902, thereby causing the mesh box 901 to rotate with the mold. Since the output shaft of the servo motor 904 is equipped with a reducer 905, the reducer 905 can reduce the speed of the output shaft of the servo motor 904, causing the stamping mold inside the mesh box 901 to rotate slowly for ion nitriding treatment.

[0028] It should be noted that, in use, this stamping die ion nitriding treatment device involves activating the electric telescopic rod 801. The output end of the electric telescopic rod 801 moves the top plate 802 upwards until the mesh box 901 and the fixing frame 805 are completely removed from the outer casing 2. The operator then climbs the ladder 6 to the upper side of the outer casing 2 and places the stamping die into the mesh box 901. After placing the stamping die, the electric telescopic rod 801 is activated again, and its output end moves the top plate 802 downwards until the sealing ring 803 engages with the slot 804. Then, the switch valve 4 on the nitrogen inlet pipe 3 is opened, allowing nitrogen to enter the outer casing 2. After sufficient nitrogen has entered, the switch valve 4 on the nitrogen inlet pipe 3 is closed, and nitrogen enters... After entering the outer shell 2, the material is first catalyzed by the catalyst layer 7, and then comes into contact with the stamping die on the grid box 901. After that, the servo motor 904 and the reducer 905 are started, so that the grid box 901 rotates slowly in the fixed frame 805. When the stamping die is ion nitrided, the servo motor 904 and the reducer 905 are stopped, and the switch valve 4 on the nitrogen outlet pipe 5 is opened, so that the nitrogen in the outer shell 2 is discharged from the nitrogen outlet pipe 5. After the nitrogen is discharged, the switch valve 4 on the nitrogen outlet pipe 5 is closed, and the electric telescopic rod 801 is started, so that the top plate 802 moves upward. After the fixed frame 805 is completely removed from the outer shell 2, the nitrided stamping die is taken out from the grid box 901, thus completing one ion nitriding treatment of the stamping die.

[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
