Description

Technical Field

[0001] The utility model relates to the field of high-pressure gas quenching vacuum furnaces, and particularly relates to a high-pressure gas quenching vacuum furnace for heat treatment processing. Background Technique

[0002] The high-pressure gas quenching vacuum furnace adopts a graphite heater and a single horizontal type with hard graphite felt as the heat insulation screen, and is equipped with a high-power quenching fan at the rear. The Fengdong high-pressure gas quenching vacuum furnace is composed of a vacuum furnace main body, a vacuum system, a water cooling system, an inflation system, a starting system, a relay control system, etc. The gas quenching vacuum furnace has a visual operation interface, is convenient and simple to operate, can be freely switched between manual and automatic modes, and can achieve full-automatic control. However, the existing high-pressure gas quenching vacuum furnace is not convenient to give an alarm reminder when the internal pressure of the high-pressure gas quenching vacuum furnace is too high and to carry out pressure relief treatment in a timely manner, thus prone to safety accidents.

[0003] To solve the above problems, a high-pressure gas quenching vacuum furnace for heat treatment processing is thus proposed here. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-pressure gas quenching vacuum furnace for heat treatment processing to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A high-pressure gas quenching vacuum furnace for heat treatment processing, including a furnace body. One side of the top end of the furnace body is fixedly provided with a mounting seat. The connection between the furnace body and the mounting seat is fixedly communicated with a connecting pipe. The top of the inner side of the connecting pipe is provided with a sealing groove. The top end of the mounting seat is fixedly provided with a fixing seat. The bottom of the inner side of the fixing seat is fixedly installed with a motor. The output end of the motor extends into the mounting seat and is fixedly connected with a lead screw. The surface of the lead screw is threadedly provided with a sleeve. One side of the sleeve is fixedly provided with a fixing block. The bottom end of the fixing block is fixedly connected with a telescopic rod and a telescopic spring. The bottom between the telescopic rod and the telescopic spring is fixedly provided with a connecting block. The bottom end of the connecting block is fixedly connected with a connecting rod. The bottom end of the connecting rod is fixedly connected with a sealing block. The sealing block is engaged with the sealing groove.

[0006] By connecting the connecting pipe with the furnace body, the sealing block will move upward against the acting force of the telescopic spring as the air pressure in the furnace body increases until the sealing block contacts the contact sensor, thereby triggering the contact sensor and feeding back the signal to the control panel, so as to control the alarm to be energized to emit a flashing red light and a beeping sound to warn relevant personnel that the internal pressure of the furnace body is too high and needs to be processed in a timely manner. If the sealing block continuously contacts the contact sensor for a period of time, the control panel will control the electric control valve to open to carry out pressure relief treatment on the furnace body to avoid continuous excessive internal pressure of the furnace body and thus cause damage to the furnace body.

[0007] Preferably, an installation rod is fixedly arranged at the bottom of one side of the inner wall of the installation seat, and a contact sensor is fixedly installed at the bottom end of the installation rod. The contact sensor is arranged corresponding to the sealing block. As the air pressure in the furnace body increases, the sealing block moves upward until it contacts the contact sensor.

[0008] Preferably, a sealing ring is fixedly arranged on the surface of the sealing block. The setting of the sealing ring can improve the sealing performance between the sealing block and the connecting pipe.

[0009] Preferably, a guide rod is fixedly arranged on the side of the fixed block away from the sleeve. The middle part of the guide rod is inserted with a guide seat, and the top end of the guide seat is fixedly connected to the top end inside the installation seat. The cooperation of the guide rod and the guide seat facilitates the stable up and down movement of the fixed block.

[0010] Preferably, a control panel is fixedly installed on one side of the installation seat. The setting of the control panel facilitates the coordinated cooperation of each mechanism.

[0011] Preferably, a pressure relief pipe is fixedly communicated with the middle part of the top end of the furnace body, and an electric control valve is fixedly installed at the connection part of the pressure relief pipe and the furnace body. The setting of the pressure relief pipe facilitates the pressure relief treatment of the furnace body.

[0012] Preferably, an alarm is fixedly installed on one side of the top end of the furnace body away from the installation seat, and support bases are fixedly arranged on both sides of the bottom end of the furnace body. The setting of the two support bases can stably support the furnace body.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. By connecting the connecting pipe with the furnace body, the sealing block will move upward against the acting force of the telescopic spring as the air pressure in the furnace body increases until the sealing block contacts the contact sensor, thereby triggering the contact sensor and feeding back the signal to the control panel, so as to control the alarm to be energized to emit a flashing red light and a beeping sound to warn relevant personnel that the internal pressure of the furnace body is too high and needs to be processed in time. If the sealing block continuously contacts the contact sensor for a period of time, the control panel will control the electric control valve to open to relieve the pressure of the furnace body and avoid damage to the furnace body due to continuously high internal pressure;

[0015] 2. By driving the screw rod to rotate by the motor, the sleeve is driven to move up and down, thereby driving the fixed block to move up and down, and then facilitating the adjustment of the initial compression length of the telescopic spring, so as to adjust the pressure trigger value and be able to adapt to different usage requirements.
