Description

Technical Field

[0001] The utility model relates to the field of quenching devices, and particularly relates to an inner cavity quenching device for a solenoid valve. Background Technique

[0002] Quenching is a heat treatment method in which a workpiece is heated to a certain high temperature and then rapidly cooled with water, oil or air to harden the surface of the workpiece. During the production and processing of the pipeline of a solenoid valve, it is necessary to quench the inner cavity of the solenoid valve pipeline to optimize the performance of the inner cavity of the solenoid valve pipeline. This solution specifically relates to an inner cavity quenching device for a solenoid valve. The existing inner cavity quenching device for a solenoid valve is not convenient for clamping and fixing the inner cavity of solenoid valve pipelines with different diameters. Moreover, since quenching requires two processes of heating and cooling, and the existing inner cavity quenching device for a solenoid valve needs to manually complete the switching of the two processes, which is not only unsafe but also reduces the efficiency of the entire quenching process.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-Figure 3As shown in the figure, a quenching device for the inner cavity of a solenoid valve includes a quenching tank 1. At the top and in the middle of the front surface of the quenching tank 1, a quenching rod 2 is fixedly installed. In front of the quenching tank 1, there is a water tank 4. At the top and in the middle of the back surface of the water tank 4, a cooling spray pipe 5 is fixedly installed. An auxiliary component 3 is arranged between the quenching tank 1 and the water tank 4. The auxiliary component 3 includes two support frames 301. At the top and both sides between the two support frames 301, limit sliding rails 303 are fixedly installed. At the bottom and both sides between the two support frames 301, lead screws 302 are arranged. On both sides near the bottom of the front surface of one of the support frames 301, servo motors 307 are fixedly installed. Between the two lead screws 302 and the two limit sliding rails 303, there is a carrier 304. At the middle of the top and bottom of the carrier 304, a cylinder 305 is fixedly installed. At the end of the piston rod of the cylinder 305, a clamping block 306 is fixedly installed.

[0018] The lead screw 302 is movably connected to the support frame 301 through a bearing, and two sections of threads with the same length and opposite directions are arranged on the outer circle of the lead screw 302. By setting the two sections of threads, it is convenient to drive the carrier 304 to move in different directions when the lead screw 302 rotates.

[0019] The carrier 304 is slidably connected to the limit sliding rail 303, and the carrier 304 is threadedly connected to the lead screw 302. The output shaft of the servo motor 307 is fixedly connected to one end of the lead screw 302. After the servo motor 307 is started, it drives the lead screw 302 to rotate. By the rotation of the lead screw 302, the carrier 304 is driven to move, and the limit sliding rail 303 is used to limit the carrier 304 to improve the stability of the carrier 304 when it moves.

[0020] The main view of the carrier 304 is arranged in a "匚" shape, and the main view of the clamping block 306 is arranged in a "V" shape. The "匚" shape setting is convenient for placing the pipeline of the solenoid valve. At the same time, the "V" shaped clamping block 306 is set to facilitate clamping and fixing the pipelines of solenoid valves with different pipe diameters.

[0021] A water pump connected to the cooling spray pipe 5 is installed inside the water tank 4. After the water pump is started, the cooling water in the water tank 4 is pumped into the cooling spray pipe 5 and sprayed out to quickly cool the pipeline of the solenoid valve after quenching heating.

[0022] It should be noted that this utility model is a quenching device for the inner cavity of a solenoid valve. When in use, first add cooling water to the water tank 4, then place the pipeline of the solenoid valve between the two clamping blocks 306, and start the cylinder 305 to drive the clamping block 306 to clamp and fix the pipeline of the solenoid valve;

[0023] After the solenoid valve pipeline is clamped and fixed, the solenoid valve inner cavity quenching device is started, and the servo motor 307 is started to drive the screw rod 302 to rotate, and the rotating screw rod 302 drives the carrier 304 to move toward the quenching box 1, and the limiting slide rail 303 is used to limit the carrier 304 to improve the stability of the carrier 304 when moving. When the solenoid valve pipeline moves to the outside of the quenching rod 2, the quenching box 1 is started to cooperate with the quenching rod 2 to quench and heat the inner cavity of the solenoid valve pipeline;

[0024] After completing the quenching heating, the servo motor 307 starts again to drive the screw 302 to reverse, and drives the mounting frame 304 to move toward the water tank 4, so that the solenoid valve pipeline moves to the outside of the cooling spray pipe 5. Then the water pump in the water tank 4 starts to transport the cooling water to the cooling spray pipe 5 to spray it out to quickly cool the inner cavity of the solenoid valve pipeline, completing the entire quenching process.

[0025] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
