Description

Technical Field

[0001] The utility model relates to the technical field of quenching machines, and particularly relates to a quenching machine with circulating cooling. Background Art

[0002] A quenching machine uses rapid cold water or other cooling media to rapidly cool the surface of metal products, causing phase transformation and deformation in its internal structure. After the metal is heated to a certain temperature, it enters the water sprayer through a conveyor belt or fixture for rapid cooling of the metal surface. The speed and temperature of the cooling medium can be adjusted and controlled by controlling the spray quenching equipment to achieve the optimal quenching effect. Usually, factories will consider the timeliness of workpiece quenching during mass production.

[0003] According to the "quenching machine with recyclable cooling for machining" with the Chinese patent publication number CN216337832U, it mainly describes the cooperation of a driving motor, a threaded rod, a threaded sleeve, a limiting rod, a placement plate, a cooling box, a return pipe, a water tank, a second water pump, a servo motor, a gear and a toothed plate. The output shaft of the driving motor drives the limiting rod to move through the threaded rod and the threaded sleeve, so that the placement plate moves into the inner cavity of the cooling box. The second water pump sprays the water cooled by the refrigerator from the water gun to cool the workpiece. The water after spraying enters the water tank through the return pipe for convenient secondary utilization. At the same time, the output shaft of the servo motor drives the toothed plate to move to the left to cover the cooling box to avoid steam leakage, thus achieving the effect of recyclable cooling and solving the problem that the existing device does not have a circulating cooling function. During the process of quenching workpieces, it is necessary to heat up and cool down multiple times, increasing the quenching time of mass-produced workpieces.

[0004] Therefore, a quenching machine with circulating cooling is proposed to solve the problem that during the process of quenching workpieces, it is necessary to heat up and cool down multiple times, increasing the quenching time of mass-produced workpieces. Content of the Utility Model

The water distribution ring is fixedly connected with the metal hose and is internally connected. Uniformly arranged nozzles are fixedly connected to the bottom end of the water distribution ring. Through holes are uniformly formed on the rotating disk.

[0007] As a preferred technical solution of the present utility model, a guide groove is formed at the bottom end of the fixed plate, and a water guide hole is formed at the lowest point of the guide groove of the fixed plate. The water guide hole is communicated with the water tank. By providing the guide groove and the water guide hole, the water body can be recycled.

[0008] As a preferred technical solution of the present utility model, limit plates are fixedly connected to four mutually distant sides of the fixed plate located in the guide groove. A filter screen is in contact with the limit plates. The filter screen has a semi-circular structure. By providing the limit plates and the filter screen, impurities contained in the water body during the water body reflux can be filtered.

Detailed implementation manners

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figures 1 - 3 A quenching machine with circulating cooling as shown, including a fixed plate 1, a support frame 2, a first push rod 3 and quenching equipment 4. The quenching equipment 4 uses high-frequency current or other existing equipment to heat the workpiece. The bottom end of the fixed plate 1 is fixedly connected with a drive motor 5, and the output end of the drive motor 5 is fixedly connected with a rotating disk 6. The drive motor 5 drives the rotating disk 6 to rotate, enabling the workpiece to rotate. Four mutually separated sides of the upper end of the rotating disk 6 are fixedly connected with receiving disks 7, and the receiving disks 7 are used to receive materials. One side of the bottom end of the fixed plate 1 is fixedly connected with a water tank 8, and a water pump is fixedly connected inside the water tank 8. The output end of the water pump is fixedly connected with a metal hose 9. One end of the metal hose 9 is fixedly connected with a waterproof cover 10. The water pump pumps water and guides it through the metal hose 9 into the water distribution ring 12, and evenly sprays it onto the workpiece through the spray heads 13 to provide the cooling process. Both sides of the upper end of the waterproof cover 10 are fixedly connected with second push rods 11. Both the first push rod 3 and the second push rod 11 are electric push rods. A support is fixedly connected inside the waterproof cover 10, and the bottom end of the support is fixedly connected with a water distribution ring 12. The water distribution ring 12 is fixedly connected with the metal hose 9 and is internally connected. The bottom end of the water distribution ring 12 is evenly fixedly connected with spray heads 13. Water passing holes 14 are evenly formed in the rotating disk 6, and the water body passes through the water passing holes 14 in the rotating disk 6 and falls to the bottom side of the rotating disk 6.

[0018] Among them, the water tank 8 is communicated with the water guiding hole 16. The water guiding hole 16 is located at the lowest point of the guide groove 15. The guide groove 15 is located at the bottom end of the fixed plate 1. By providing the guide groove 15 and the water guiding hole 16, it is convenient to recycle the cooling water.

[0019] Among them, the filter screen 18 contacts the limiting plate 17. The limiting plate 17 is fixedly connected to the fixing plate 1, and the limiting plate 17 is located on the four sides away from each other in the guide groove 15. The filter screen 18 is in a semi-circular structure. By setting two filter screens 18, the water body can be filtered, and at the same time, the filter screen 18 can be conveniently disassembled and cleaned.

[0020] Among them, the fixing plate 1 contacts the spherical ball 19. The spherical ball 19 is rotationally embedded at the bottom end of the support rod 20. The support rod 20 is located at the bottom end of the fixing plate 1. By setting the spherical ball 19 and the support rod 20, the support for the rotating disc 6 is provided, and at the same time, the friction between the support rod 20 and the fixing plate 1 can be reduced.

[0021] Among them, the inclination of the waterproof cover 10 is the same as that of the cross groove 21. The cross groove 21 is located at the upper end of the rotating disc 6. By setting the cross groove 21, when the second push rod 11 drives the waterproof cover 10 to move downward, it can be stuck in the cross groove 21 of the rotating disc 6, increasing the sealing effect, so that the heating gas can only pass through the bottom side of the water passing hole 14.

[0022] Working principle: Place the workpiece on the receiving disc 7, and then the first push rod 3 drives the quenching device 4 to move downward to heat the workpiece. After heating is completed, the driving motor 5 can be started to drive the rotating disc 6 to rotate and make the receiving disc 7 located under the waterproof cover 10. At this time, the second push rod 11 drives the waterproof cover 10 and the water distribution ring 12 to move downward. At this time, the waterproof cover 10 fits with the cross groove 21 on the rotating disc 6. Thus, the water pump pumps the water body through the metal hose 9 and injects it into the water distribution ring 12 and the spray heads 13 to be in uniform contact with the workpiece. After the water body is cooled, it falls into the guide groove 15 through the water passing hole 14 on the rotating disc 6, and then flows back to the water tank 8 through the water guiding hole 16 to complete the recovery of the water body. At the same time, the heating of the workpiece and the cooling of the workpiece are carried out synchronously, which can shorten the quenching time of the workpiece and improve the efficiency of cyclic quenching.

[0023] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.

[0024] Other parts not detailed in the present invention belong to the prior art, so they will not be elaborated here.

[0025] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
