Description

Technical Field

[0001] The utility model relates to the field of nitriding furnaces, in particular to a mold surface nitriding furnace. Background Art

[0002] The mold surface nitriding furnace refers to a chemical heat treatment equipment that allows nitrogen atoms to penetrate into the mold surface in a certain medium at a certain temperature. The mold treated with nitriding has excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance. Most of the existing nitriding furnaces are as follows Figure 1 As shown, the problem with this technical solution is that when the existing nitriding furnace is used, a top crane hoist is required to lift the frame with the mold and put it into or lift it out of the furnace. During this process, the hanging rope and hook of the lifting frame will shake to a certain extent. During the shaking process, the frame and the furnace body will produce friction and collision. As the use time increases, the inner wall of the furnace body or the frame is easily deformed and damaged, which is inconvenient to use. Utility Model Content

[0003] The purpose of the utility model is to solve the following problems existing in the prior art: when the existing nitriding furnace is used, a top crane hoist is required to lift a frame equipped with a mold and put it into or lift it out of the furnace. During this process, the hanging rope and the hook for lifting the frame will shake to a certain extent. During the shaking process, friction and collision will occur between the frame and the furnace body. As the use time increases, the inner wall or frame of the furnace body is easily deformed and damaged, which is inconvenient to use.

[0004] In order to solve the problems existing in the prior art, the utility model provides a mold surface nitriding furnace, including a nitriding furnace body, a lifting assembly is provided on the inner side of the nitriding furnace body, a limit seat is provided on the inner side of the lifting assembly through a slider, a sliding seat is provided on the top of the limit seat, and a clamping block is provided on the top of the sliding seat.

[0005] Furthermore, a connecting piece is provided on the top of the card block, and a hook hole is provided inside the connecting piece. The connecting piece with the hook hole facilitates the staff to use tools to push the card block to move, thereby avoiding burns caused by manual operation.

[0006] Furthermore, the lifting assembly is composed of a lifting seat and a lifting rod, and a damping assembly is provided between the inner side of the slider and the lifting rod. The damping assembly prevents the slider from falling due to gravity when no external force is applied, making it convenient for the staff to dock the carrier with the limit seat at the furnace top.

[0007] Furthermore, the height of the lifting assembly is the same as the internal height of the nitriding furnace body. The lifting assembly and the slider are lifted and lowered in cooperation with the auxiliary limit seat to ensure its stability.

[0008] Furthermore, the limiting seat is circular in shape, and a plurality of vents are arranged inside the limiting seat. The circular limiting seat is adapted to the internal size of the nitriding furnace body, and the vents do not affect the nitriding process.

[0009] Furthermore, the limit assembly consisting of the slide seat, the clamping block and the connecting piece is provided with three groups, and the three groups of the limit assembly are arranged in a circular array on the top of the limit seat. The staff uses a tool buckled on the hook hole of the connecting piece to push the clamping block to move on the slide seat, so that the clamping block can be pushed into the gap of the net frame to connect with the net frame.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The staff of the utility model uses a tool buckle to the hook hole of the connecting piece to push the card block to move on the sliding seat, so that the card block can be pushed into the gap of the net frame and connected with the net frame. At this time, after the hook of the traveling crane is released, the sliding block is limited by the pressure of the net frame on the limiting seat to drive the limiting seat to descend on the lifting assembly, and the hook of the traveling crane is hung on the net frame again for lifting. During the lifting process, the limiting seat follows the lifting assembly to rise until it is lifted to the top of the furnace. The staff again uses the tool to buckle into the hook hole of the connecting piece to pull the card block to reset and release the card connection with the net frame. The limiting assembly composed of the sliding seat, the card block and the connecting piece can limit the net frame equipped with the mold and then connect it to the limiting seat. Then the lifting and lowering of the limiting seat with the assistance of the lifting assembly and the sliding block can achieve the effect of increasing the stability of material discharge and material retrieval, avoid the repeated collision and friction between the loading tool and the nitriding furnace body during the material discharge and material retrieval process, thereby increasing the practicality of the device.

[0020] Description of the working principle: the staff first places the mold to be nitrided in the frame, and then uses the crane to lift the frame to the limit seat 4 on the top of the nitriding furnace body 1. Then the staff uses a tool to buckle on the hook hole of the connecting piece 7 to push the block 5 to move on the slide seat 3, so that the block 5 can be pushed into the gap of the mesh frame and connected to the mesh frame. At this time, after releasing the hook of the crane, the slider 6 is restricted by the pressure of the frame on the limit seat 4 to drive the limit seat 4 to descend on the lifting assembly 2 until it descends to the appropriate position. After the staff releases the hook of the crane and closes the furnace cover, the nitriding furnace body 1 can be started to nitridate the mold therein. When the nitriding work is completed, the staff opens the furnace cover and hangs the hook of the crane again on the mesh. The frame is lifted up behind it. During the lifting process, the limit seat 4 follows the lifting component 2 to rise. When it is lifted to the top of the furnace, the staff again uses the tool to buckle into the hook hole of the connecting piece 7 to pull the clamping block 5 to reset and release the clamping connection with the mesh frame. At this time, the mesh frame and the mold displacement therein can be lifted by the crane hoist to proceed to the next process. The mesh frame with the mold can be limited by the limit assembly composed of the above-mentioned slide seat 3, the clamping block 5 and the connecting piece 7, and then it can be connected to the limit seat 4. Then, the lifting component 2 and the slider 6 assist the lifting of the limit seat 4 to achieve the effect of increasing the stability of material discharge and material collection, thereby avoiding the situation where the loading tool and the nitriding furnace body 1 are repeatedly damaged by collision and friction during the discharge and material collection process, thereby increasing the practicality of the device.

[0021] The nitriding furnace body 1 is mainly used for nitriding the mold. When selecting, a conventional one can be selected from the prior art according to the needs.

[0022] The lifting assembly 2 is mainly used to cooperate with the slider 6 to assist the limiting seat 4 in lifting. When selected, the lifting assembly 2 is composed of a lifting seat and a lifting rod, and a damping assembly is provided between the inner side of the slider 6 and the lifting rod.

[0023] The slide seat 3 is mainly used for telescopic adjustment of the clamping block 5. When selecting, a conventional one can be selected from the prior art according to the needs.

[0024] The limiting seat 4 is mainly used for docking with a carrier for loading the mold. When selected, the limiting seat 4 is circular in shape, and a plurality of ventilation holes are arranged inside the limiting seat 4 .

[0025] The clamping block 5 is mainly used to cooperate with the slide seat 3 and clamp the carrier for loading the mold. When selecting, a conventional one can be selected from the existing technology according to the needs.

[0026] The slider 6 is mainly used to cooperate with the lifting assembly 2 to assist the limit seat 4 in lifting. When selecting, a conventional one can be selected from the existing technology according to needs.
