Description

Technical Field

[0001] This utility model relates to the field of metal material surface treatment technology, specifically to a pulse power integrated glow discharge ion nitriding furnace. Background Technology

[0002] Glow discharge ion nitriding, an important surface strengthening process, utilizes glow discharge in a vacuum environment to infiltrate nitrogen ions into the metal surface, significantly improving the workpiece's hardness, wear resistance, and fatigue resistance. Traditional nitriding furnaces mostly employ resistance heating, using external power supplies and discrete temperature control systems for process control, and are widely used in automotive molds, precision machinery, and other fields.

The integrated power module 104 is integrated at the bottom of the nitriding furnace 101, and the support 105 supports the bottom of the integrated power module 104. The mounting base 106 is fixedly provided inside the furnace body of the nitriding furnace 101. The nitriding furnace 101 is divided into inner and outer layers, with a temperature control layer between the inner and outer layers. The temperature control layer is connected to a temperature control structure 2, and a compression structure 3 is provided on the temperature control structure 2. The compression structure 3 is connected to a valve structure 4. The nitrogen port 102 of the furnace body structure 1... Two nitrogen inlets are provided: one connected to a nitrogen tank for introducing nitrogen into the nitriding furnace 101, and the other nitrogen inlet 102 connected to an exhaust system for treating waste gas.

The compression structure 3 is the drive unit of the temperature control structure 2 and is the main temperature regulation device. The valve structure 4 can control the opening and closing of the hot and cold pipes.

[0023] The temperature control structure 2 includes an outer shell 201, an inner shell 202, a temperature control cavity 203, and a guide rod 204. The inner shell 202 is located inside the outer shell 201, and the temperature control cavity 203 is located between the outer shell 201 and the inner shell 202. The guide rod 204 is fixedly installed on the inner wall of the inner shell 202.

The temperature control cavity 203 is connected to the air guide cavity 306 and the compression cavity 305 of the compression structure 3 through a valve structure 4. The temperature control is achieved by the pressure change in the compression cavity 305, thereby controlling the temperature of the refrigerant of a certain mass in the temperature control cavity 203, thereby realizing the rapid adjustment of direct cooling and heating of the nitriding furnace 101 and improving the temperature control effect.

[0024] The compression structure 3 includes an adjusting motor 301, a threaded rod 302, an extrusion block 303, a guide groove 304, a compression chamber 305, and a gas guide chamber 306.

The first on / off valve 402 and the second on / off valve 405 are respectively connected to the first pipe body 401 and the second pipe body 404. The first on / off valve 402 is connected to the first one-way valve 403 through a pipe, and the second on / off valve 405 is connected to the second one-way valve 406 through a pipe. The first pipe body 401 is a thermal control channel. The first one-way valve 403 can control the on / off state of the first pipe body 401. The valve 403 is a one-way valve from the gas guide chamber 306 to the temperature control chamber 203, which can transmit the high pressure of the compression chamber 305 to the temperature control chamber 203, thereby compressing and heating the refrigerant in the temperature control chamber 203. The second pipe 404 is a cold control channel. The second one-way valve 406 can control the opening and closing of the second pipe 404. The second one-way valve 406 is a one-way valve from the temperature control chamber 203 to the gas guide chamber 306, which can connect the compression chamber 305 to the temperature control chamber 203 at low pressure, thereby cooling the refrigerant in the temperature control chamber 203 in a low-pressure environment. Through the control of the hot and cold pipes, rapid heating and cooling of the furnace body can be achieved.

[0026] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0027] In summary, with the help of the above-mentioned technical solution of this utility model, the furnace body structure 1 has two nitrogen ports 102. One port is connected to a nitrogen tank for introducing nitrogen into the nitriding furnace 101, and the other port 102 is connected to an exhaust device for treating waste gas. The integrated power module 104 is integrated at the bottom of the nitriding furnace 101. The sensor interface 103 is used to connect a temperature sensor and other sensors to monitor various parameters inside the furnace in real time. The mounting base 106 is used to install a fixing bracket, which is used to clamp and fix the workpiece to be processed. The temperature control structure 2 can control the refrigerant in the temperature control layer. For temperature and heat regulation, the inner wall of the nitriding furnace 101 is made of a good thermal conductive material.

The compression structure 3 is the driving unit of the temperature control structure 2 and serves as the main temperature regulation device. The valve structure 4 controls the on / off operation of the hot and cold pipes. A temperature control cavity 203 is formed between the outer shell 201 and the inner shell 202 of the temperature control structure 2. The temperature control cavity 203 is connected to the temperature control layer. The temperature control cavity 203 is connected to the air guide cavity 306 and the compression cavity 305 of the compression structure 3 through the valve structure 4. The pressure change within the compression cavity 305 then controls the temperature control cavity 203. 3. A certain mass of refrigerant is used for temperature control, thereby achieving rapid adjustment of direct cooling and heating of the nitriding furnace 101 and improving the temperature control effect. The regulating motor 301 of the compression structure 3 drives the threaded rod 302, which in turn drives the extrusion block 303 to move up and down linearly under the guidance of the guide groove 304 and the guide rod 204. This allows the extrusion block 303 to compress and adjust the space of the compression chamber 305 through the sealed expansion joint, thereby achieving refrigerant temperature control. The first pipe body 401 is a heat control channel, and the first one-way valve 403 can control the opening and closing of the first pipe body 401. The first one-way valve 403 is a guide The one-way valve from the gas chamber 306 to the temperature control chamber 203 allows the high pressure from the compression chamber 305 to be transferred to the temperature control chamber 203, thereby compressing and heating the refrigerant in the temperature control chamber 203. The second pipe 404 is a cold control channel, and the second one-way valve 406 controls the opening and closing of the second pipe 404. The second one-way valve 406 is a one-way valve from the temperature control chamber 203 to the gas chamber 306, allowing the compression chamber 305 to connect with the temperature control chamber 203 at low pressure, thereby allowing the refrigerant in the temperature control chamber 203 to cool down in a low-pressure environment. Through the control of the hot and cold pipes, rapid heating and cooling of the furnace body can be achieved.
