Description

Technical Field

[0001] The utility model relates to the technical field of hardware quenching, in particular to a hardware production and processing heat treatment device. Background Art

[0002] During the processing of hardware, one of the processes is quenching. The purpose of quenching is to transform the supercooled austenite into martensite or bainite to obtain martensite or bainite structure, and then tempering at different temperatures to greatly improve the rigidity, hardness, wear resistance, fatigue strength and toughness of the steel, so as to meet the different use requirements of various mechanical parts and tools. Quenching can also meet the special physical and chemical properties of some special steels such as ferromagnetism and corrosion resistance.

[0003] When using traditional quenching equipment, the temperature of the water will continue to rise during the continuous quenching process. As the temperature continues to rise, the quenching effect will be greatly reduced. Therefore, how to keep the water temperature at an appropriate state during the quenching process is a problem that needs to be considered. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a hardware production and processing heat treatment equipment. When in use, the equipment utilizes the cooling effect of the vortex tube to keep the quenching liquid temperature at an appropriate temperature at all times, thereby ensuring the overall quenching effect.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The cam is fixedly provided with an L-shaped plate at the upper end thereof, and the horizontal part of the L-shaped plate is symmetrically fixedly connected to the two hydraulic telescopic rods, and the telescopic ends of the hydraulic telescopic rods are jointly fixedly connected to the movable plate, and the movable plate is penetrated by a rotating rod, and a placing net disk is penetrated on the rotating rod, and the placing net disk is fixedly connected to the rotating rod; a cold air mechanism comprises a vortex tube arranged on the left side of the rectangular cylinder, and the inner bottom of the rectangular cylinder is penetrated by a vertical tube, and the vertical tube is fixedly connected to the inner wall of the rear side of the rectangular cylinder, and the horizontal bar is vertically rotatably connected to the rotating tube, and the rotating tube is a tube body sealed at the upper end thereof, and a plurality of jet nozzles are connected to the outer side of the upper end portion of the rotating tube, and the lower end of the rotating tube is connected to the upper end of the vertical tube by a rotating joint, and the cold air end of the vortex tube is connected to the lower end of the vertical tube; the rotating mechanism is used to drive the rotating tube to rotate.

[0007] Preferably, the upper end of the rotating tube is fixedly connected to a rectangular bar, and the upper end of the rectangular bar passes through the rotating rod and is slidably connected to the rotating rod.

[0008] Preferably, the rotating rod and the movable plate are rotatably connected via a bearing.

[0009] Preferably, the rotating mechanism includes a motor mounted on the upper end of the horizontal portion of the L-shaped plate, and the output shaft of the motor extends into the interior of the rectangular tube.

[0010] Preferably, pulleys are installed on the output shaft of the motor and the rotating tube, and the two pulleys are connected by a transmission belt.

[0011] Preferably, a plurality of stirring rods are fixedly connected to the outer side of the upper end portion of the rotating tube.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. A vortex tube is provided. Through the principle of vortex tube refrigeration, low-temperature and high-pressure air can be discharged from the jet pipe and enter the quenching liquid in the form of bubbles. The quenching liquid is cooled by heat transfer, so that the quenching liquid is always at a suitable temperature during the quenching process to ensure the quenching quality. In addition, the motor can be used to drive multiple stirring rods to rotate. The rotation of the stirring rods can break up the bubbles, thereby making the heat exchange between the low-temperature gas and the water more uniform and the overall cooling more uniform.

[0014] 2. The rotation of the motor will also cause the hardware to rotate. During quenching, it helps the quenching liquid to evenly surround the surface of the hardware, thereby avoiding adverse tissue or stress concentration in local areas due to overheating. After quenching, the excess liquid attached to the hardware will be quickly thrown off to facilitate subsequent processing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

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

[0020] Reference Figure 1-Figure 3 A hardware production and processing heat treatment equipment includes a rectangular cylinder 1, the upper end of the rectangular cylinder 1 is fixedly connected to an L-shaped plate 2, the horizontal part of the L-shaped plate 2 is symmetrically fixedly connected to two hydraulic telescopic rods 4, the telescopic ends of the two hydraulic telescopic rods 4 are fixedly connected to a movable plate 5, the movable plate 5 is penetrated by a rotating rod 6, the rotating rod 6 is rotatably connected to the movable plate 5 through a bearing, the rotating rod 6 is penetrated by a placement net disk 8, and the placement net disk 8 is fixedly connected to the rotating rod 6;

[0021] The air inlet of the vortex tube 3 is connected to the external high-pressure gas storage box, and an electromagnetic valve is installed at the connection point, and air supply can be realized by starting the electromagnetic valve. A vertical pipe 17 is provided through the inner bottom of the rectangular tube 1, and the vertical pipe 17 is fixedly connected to the inner bottom of the rectangular tube 1. A horizontal bar 10 is fixedly connected to the inner wall of the rear side of the rectangular tube 1, and the horizontal bar 10 is vertically rotatably connected to the rotating tube 11. A check valve is installed in the rotating tube 11. The rotation here is also achieved by a bearing. The rotating tube 11 is a tube body sealed at the upper end. The outer side of the upper end part of the rotating tube 11 is connected to a plurality of injection pipes 13. The lower end of the rotating tube 11 is connected to the upper end of the vertical pipe 17 through a rotary joint 12. The cold air end of the vortex tube 3 is connected to the lower end of the vertical pipe 17. The upper end of the rotating tube 11 is fixedly connected to the rectangular bar 7. The upper end of the rectangular bar 7 passes through the rotating rod 6 and is slidably connected to the rotating rod 6.

[0022] It also includes a rotating mechanism, which is used to drive the rotating tube 11 to rotate. The rotating mechanism includes a motor 9 installed at the upper end of the horizontal part of the L-shaped plate 2. The output shaft of the motor 9 extends to the inside of the rectangular tube 1. Pulleys 15 are installed on the output shaft of the motor 9 and the rotating tube 11. The two pulleys 15 are connected by a transmission belt 16. A plurality of stirring rods 14 are fixedly connected to the outer side of the upper end part of the rotating tube 11.

[0023] In the present invention, the rectangular cylinder 1 is filled with water, and the heated hardware is placed on the placement mesh plate 8. Then, the hydraulic telescopic rod 4 is started to move downward, so that the placement mesh plate 8 enters the quenching liquid. Then, the external solenoid valve is started to supply high-pressure gas into the vortex tube 3. The low-temperature and high-pressure airflow at the cold air end of the high-pressure gas will enter the vertical pipe 17, and then enter the rotating tube 11, and finally be discharged from the air injection pipe 13 and enter the quenching liquid in the form of bubbles. The quenching liquid is cooled by heat transfer, so that the quenching liquid is always at a suitable temperature during the quenching process.

[0024] During this process, the motor 9 can be started. After the motor 9 is started, the rotating tube 11 will rotate through the transmission of the pulley 15 and the transmission belt 16, thereby rotating the multiple stirring rods 14. The rotation of the stirring rods 14 can break up the bubbles, thereby making the heat exchange between the low-temperature gas and the water more uniform and the overall temperature reduction uniform. In addition, the rotation of the rotating tube 11 will drive the rectangular bar 7 to rotate, thereby rotating the placement mesh plate 8 through the rotating rod 6. The rotation of the placement mesh plate 8 can make the hardware move relative to the water body, which helps the quenching liquid to evenly surround the surface of the hardware, thereby avoiding the generation of adverse tissue or stress concentration in local areas due to overheating;

[0025] When quenching is completed, the solenoid valve and motor 9 are closed, and the two hydraulic telescopic rods 4 are started to retract, and the movable plate 5 is moved up to leave the quenching liquid. At this time, the motor 9 is started to make the placement net plate 8 rotate rapidly, and the centrifugal force is used to quickly throw off the excess liquid attached to the hardware, which is convenient for subsequent processing.
