Description

Technical Field

[0001] The utility model relates to the technical field of carburizing quenching furnaces, in particular to a gas carburizing multi-purpose furnace. Background Technique

[0002] A gas carburizing multi-purpose furnace is a device integrating multiple heat treatment functions, and is widely used in fields such as mechanical manufacturing, auto parts, and aerospace. The gas carburizing multi-purpose furnace mainly infiltrates carbon atoms into the surface of the workpiece by introducing carburizing gas into the furnace at high temperature, so as to achieve the purpose of improving the surface hardness, wear resistance and fatigue strength of the workpiece.

[0003] During the working process of the gas carburizing multi-purpose furnace, although there is heat insulation material and heat insulation design on the furnace body, the temperature of its outer surface is still relatively high. If the worker directly touches the overheated outer surface of the furnace body or gets too close, it is possible to be scalded. Therefore, there is an urgent need for a gas carburizing multi-purpose furnace with a protective structure. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a gas carburizing multi-purpose furnace.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A gas carburizing multi-purpose furnace includes a gas carburizing multi-purpose furnace body. A base is arranged at the bottom of the gas carburizing multi-purpose furnace body. A plurality of mounting seats are arranged on the base. Fixed columns are vertically inserted and adapted on the mounting seats, and the fixed columns are respectively fixedly connected to a sub-protective frame and a mother-protective frame; the sub-protective frame and the mother-protective frame are assembled and adapted on the outside of the gas carburizing multi-purpose furnace body. Lower connectors are fixedly arranged at the ends of the sub-protective frame, and upper connectors are correspondingly arranged on the mother-protective frame for adapting to the lower connectors.

[0007] In addition, the preferred structure is that there are four mounting seats, and two fixing cavities are vertically penetrated through the mounting seats, and the fixing cavities are all adapted to the fixed columns.

[0008] In addition, the preferred structure is that two fixed columns are in a group and are adapted to the two fixing cavities on the mounting seat. The tops of the two fixed columns are connected by a top cover, and a bottom plate is fixedly arranged between the bottoms of the two fixed columns.

[0009] In addition, the preferred structure is that the sub-protective frame is fixedly connected to three groups of fixed columns, and the mother-protective frame is fixedly connected to the remaining group of fixed columns.

[0010] In addition, the preferred structure is that through holes are vertically opened on the bottom plate, screws are inserted and adapted in the through holes, and threaded holes are correspondingly opened on the mounting seat for adapting to the screws.

[0011] In addition, a preferred structure is that clamping columns are vertically and fixedly arranged downward on both sides of the bottom of the upper connecting member, and clamping cavities are correspondingly formed on the lower connecting member for adapting to the clamping columns.

[0012] The beneficial effects of the present utility model are as follows: Through the clamping between the fixing column and the fixing cavity, and in cooperation with the adaptive clamping between the clamping column and the clamping cavity, the sub-protective frame and the mother-protective frame can be adaptively installed on the outer side of the gas carburizing multi-purpose furnace body. In this way, the sub-protective frame and the mother-protective frame can prevent direct contact between the staff and the outer wall of the gas carburizing multi-purpose furnace body, so as to reduce the high-temperature risk of the outer wall of the gas carburizing multi-purpose furnace body to the staff.

Detailed Embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Referring to Figures 1-5, A multi-purpose gas carburizing furnace, including the multi-purpose gas carburizing furnace body 1, a base is provided at the bottom of the multi-purpose gas carburizing furnace body 1, a plurality of mounting seats 11 are provided on the base, and fixing columns 5 are vertically inserted and adapted on the mounting seats 11, and the fixing columns 5 are respectively fixedly connected to the sub-protective frame 2 and the mother protective frame 3. The sub-protective frame 2 and the mother protective frame 3 are adaptively assembled on the outside of the multi-purpose gas carburizing furnace body 1, lower connectors 21 are fixedly provided at the ends of the sub-protective frame 2, and upper connectors 31 are adaptively provided on the mother protective frame 3 corresponding to the lower connectors 21.

[0021] Among them, a heating component and a carburizing tank are provided inside the multi-purpose gas carburizing furnace body 1. The temperature inside the furnace is raised to 900 °C to 950 °C by electric heating or other means, and then a carbon-containing gas is introduced into the furnace. The carbon-containing gas is, for example, carbon monoxide, and these gases decompose at high temperatures to produce active carbon atoms. Chemical reactions occur between the iron atoms on the surface of the metal workpiece and the active carbon atoms to achieve carburizing of the workpiece. It should be noted that the specific structure and working method of the multi-purpose gas carburizing furnace body 1 are all prior arts, so they will not be elaborated in this utility model.

[0022] Among them, there are four mounting seats 11, and two fixing cavities 12 are vertically penetrated on each mounting seat 11, and the fixing cavities 12 are all adapted to the fixing columns 5. By inserting the fixing columns 5 into the fixing cavities 12, the installation of the fixing columns 5 can be realized.

[0023] Among them, two fixing columns 5 are in a group and are adapted to the two fixing cavities 12 on the mounting seat 11. The tops of the two fixing columns 5 are connected by a top cover 51, and a bottom plate 52 is fixedly provided between the bottoms of the two fixing columns 5. When the bottom of the fixing column 5 passes through the fixing cavity 12 and contacts the ground, the bottom plate 52 between the two fixing columns 5 is adapted to move to the top of the mounting seat 11 on the multi-purpose gas carburizing furnace body 1.

[0024] Among them, the sub-protective frame 2 is fixedly connected to three groups of fixing columns 5, and the mother protective frame 3 is fixedly connected to the remaining group of fixing columns 5.

[0025] Among them, through holes 53 are vertically opened on the bottom plate 52, screws 4 are vertically inserted and adapted in the through holes 53, and threaded holes 13 are adapted to the screws 4 on the mounting seat 11. By passing the screws 4 through the through holes 53 and inserting them into the threaded holes 13, the fixed connection between the mounting seat 11 and the bottom plate 52 can be realized.

[0026] Among them, two sides at the bottom of the upper connector 31 are vertically fixed and provided with clamping columns 32 downward, and clamping cavities 22 are adapted to the clamping columns 32 on the lower connector 21. Through the adaptive clamping between the clamping columns 32 and the clamping cavities 22, the mutual connection between the upper connector 31 and the lower connector 21 can be realized.

[0027] In this embodiment, before the gas carburizing multi-purpose furnace body 1 is used, the sub-protective frame 2 and the mother protective frame 3 can be installed on the outside of the gas carburizing multi-purpose furnace body 1 to prevent direct contact between the staff and the outer surface of the gas carburizing multi-purpose furnace body 1, thereby preventing the high-temperature risk outside the gas carburizing multi-purpose furnace body 1.

[0028] Further, when the user needs to install the sub-protective frame 2 and the mother protective frame 3, only three groups of fixing columns 5 on the sub-protective frame 2 need to be inserted from above the mounting seat 11 into the fixing cavity 12 and fixed. After the fixing columns 5 are inserted, the bottom plates 52 are all located above the mounting seat 11, and at this time, the through holes 53 are aligned with the threaded holes 13. The user only needs to pass the screw 4 through the through hole 53 and insert it into the threaded hole 13 at this time, so as to realize the fixed installation of the fixing column 5 and the sub-protective frame 2.

[0029] Further, then the user only needs to insert the remaining group of fixing columns 5 on the mother protective frame 3 into the fixing cavity 12 in the mounting seat 11 and fix them with screws 4. And during the installation of the mother protective frame 3, the clamping columns 32 on the upper connecting member 31 at the end of the mother protective frame 3 need to be inserted into the clamping cavities 22 on the lower connecting member 21 of the sub-protective frame 2 in a matching manner. In this way, through the matching clamping between the clamping columns 32 and the clamping cavities 22, the stability of the sub-protective frame 2 and the mother protective frame 3 after installation can be enhanced. When the gas carburizing multi-purpose furnace body 1 is not in use, the sub-protective frame 2 and the mother protective frame 3 can also be quickly and conveniently disassembled.

[0030] In this utility model, through the clamping between the fixing column 5 and the fixing cavity 12, and in cooperation with the matching clamping between the clamping column 32 and the clamping cavity 22, the sub-protective frame 2 and the mother protective frame 3 can be adaptively installed on the outside of the gas carburizing multi-purpose furnace body 1, so that the sub-protective frame 2 and the mother protective frame 3 can prevent direct contact between the staff and the outer wall of the gas carburizing multi-purpose furnace body 1, thereby reducing the high-temperature risk caused by the outer wall of the gas carburizing multi-purpose furnace body 1 to the staff.

[0031] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
