Abstract
Description
Technical Field
[0001] The utility model relates to the field of hardware processing, and specifically relates to a cooling device for a hot stretching device of hardware parts. Background Technique
[0002] In the process of processing various hardware parts, it is necessary to perform hot stretching on them, so that the hardware parts undergo a series of deformation processes such as extrusion and stretching at high temperatures, so that the hardware parts can obtain the required shape and size. After the hot stretching of the hardware parts, it is necessary to cool them, so that the size and shape of the hardware parts are fixed, and at the same time, the internal stress and strain of the hardware parts can be eliminated, thereby improving the hardness, strength and toughness of the material.
[0003] At present, the hardware parts are usually cooled by water quenching and oil quenching. Compared with water quenching, oil quenching can effectively reduce the deformation and cracking of metals. However, during the oil quenching process, the temperature of the mineral oil near the hardware parts rises relatively fast. Too high oil temperature will accelerate the oxidation of the oil and affect the cooling effect. In addition, uneven oil temperature will lead to a large temperature gradient on the metal surface and is prone to uneven tissue structure. Therefore, a cooling device for a hot stretching device of hardware parts is proposed for the above problems. Content of the Utility Model
[0004] In order to make up for the deficiencies of the prior art and avoid the problem of poor oil quenching effect caused by the relatively fast local temperature rise of the mineral oil, the utility model proposes a cooling device for a hot stretching device of hardware parts.

[0006] The stirring component includes a fixed sleeve fixedly installed at the center of the bottom wall of the cold extraction tank, a rotating pipe is rotatably connected inside the fixed sleeve, through holes are opened at the bottom of the rotating pipe, spiral grooves are opened on the inner wall of the rotating pipe, an adjusting device is arranged on the surface of the top of the rotating pipe, an elastic rod is fixedly installed at the center of the top of the cold extraction tank, a top rod is fixedly installed at the top of the elastic rod, and a convex rod is fixedly installed on the surface of the bottom of the top rod.

When the top rod drives the convex rod to move downward, the convex rod will push the rotating pipe to rotate inside the spiral groove.
[0008] Preferably, the adjusting device includes a concave block fixedly installed on the top surface of the rotating pipe. A rotating rod is rotatably connected inside the concave block. A stirring rod is rotatably connected to the surface of the rotating rod. A hexagonal groove is formed inside the end face of the rotating rod. An expansion rod is fixedly installed on the end face of the concave block, and a hexagonal block is fixedly installed at the other end of the expansion rod.
[0009] Preferably, the stirring rod is rotatably connected inside the concave block. One end of the rotating rod penetrates through the concave block and extends to the outside of the concave block. The hexagonal block and the hexagonal groove are adaptively clamped. The operator can push the expansion rod to shorten and drive the hexagonal block to be clamped inside the hexagonal groove. At this time, the rotating rod cannot rotate continuously, that is, the rotating rod stirs the mineral oil inside the cold extraction tank at the current position.
[0010] Preferably, the blocking component includes vertical grooves opened on the left and right sides of the inner wall of the cold extraction tank. A vertical rod is fixedly installed inside the vertical groove. A slider is slidably connected to the surface of the vertical rod. One end of the slider close to the center of the cold extraction tank is fixedly installed with a baffle. Concave holes are formed on the surface of the baffle.

[0011] Preferably, the slider is slidably connected inside the vertical groove. The height of the top of the baffle gradually decreases from the center of the cold extraction tank to the edge direction. The impurities precipitated inside the cold extraction tank will fall on the surface of the baffle and then slide down to the bottom of the cold extraction tank on the surface of the baffle.
[0012] Preferably, the lifting component includes a placing frame arranged above the cold extraction tank. Flow grooves are formed on the surface of the placing frame. A steel cable is fixedly installed at the top end of the placing frame.
[0013] The beneficial effects of the present utility model are as follows:
[0014] After the heat-stretched hardware parts are placed inside the placing frame in the present utility model, the placing frame drives the hardware parts to move down into the cold extraction tank. At this time, the stirring rod rotates inside the cold extraction tank and stirs the mineral oil inside the cold extraction tank, making the temperature distribution of the mineral oil inside the cold extraction tank uniform, thereby improving the cold extraction effect on the hardware parts.
[0015] By placing the hardware parts inside the placing frame and driving the hardware parts to move down through the placing frame, manual operation is not required, avoiding the generation of open flames on the oil surface during the oil quenching process and causing harm to the operator.
[0016] When the impurities generated during the cold extraction process fall to the bottom of the cold extraction tank, the baffle blocks the impurities, preventing the impurities from rising to the surface of the subsequent cold-extracted hardware parts under the action of the vortex flow during the stirring of the mineral oil, thereby improving the cold extraction effect on the hardware parts.

[0026] The following will further elaborate on this application in conjunction with the attached Figures 1-6 and make a more detailed description of the present application.
[0027] An embodiment of the present application discloses a cooling device for a hot stretching device of hardware parts. Refer to Figure 1 and Figure 2 , a cooling device for a hot stretching device of hardware parts, including a cold extraction tank 1, a lifting component 2 is arranged above the cold extraction tank 1, the lifting component 2 includes a holding frame 21 arranged above the cold extraction tank 1, a flow groove 22 is opened on the surface of the holding frame 21, a steel cable 23 is fixedly installed at the top end of the holding frame 21, blocking components 3 are arranged on both the left and right sides inside the cold extraction tank 1, and a stirring component 4 is arranged in the middle inside the cold extraction tank 1;
[0028] Refer to Figures 2-5 , the stirring component 4 includes a fixed sleeve 41 fixedly installed at the center of the bottom wall of the cold extraction tank 1, a rotating pipe 42 is rotatably connected inside the fixed sleeve 41, a through hole 43 is opened at the bottom of the rotating pipe 42, a spiral groove 44 is opened on the inner wall of the rotating pipe 42, an adjusting device 45 is arranged on the surface at the top of the rotating pipe 42, an elastic rod 46 is fixedly installed at the center of the top end of the cold extraction tank 1, a top rod 47 is fixedly installed at the top end of the elastic rod 46, a convex rod 48 is fixedly installed on the surface at the bottom of the top rod 47, the bottom end of the rotating pipe 42 is rotatably connected to the bottom wall of the cold extraction tank 1, the through hole 43 penetrates through the inner and outer sides of the rotating pipe 42, the top rod 47 penetrates through the top wall of the rotating pipe 42 and is rotatably connected inside the rotating pipe 42, and one end of the convex rod 48 away from the top rod 47 is slidably connected inside the spiral groove 44. When the top rod 47 drives the convex rod 48 to move downward, at this time the convex rod 48 will push the rotating pipe 42 to rotate inside the spiral groove 44.
[0029] Refer to Figures 3-6 , the adjusting device 45 includes a concave block 451 fixedly installed on the surface at the top of the rotating pipe 42, a rotating rod 452 is rotatably connected inside the concave block 451, a stirring rod 453 is rotatably connected to the surface of the rotating rod 452, a hexagonal groove 454 is opened inside the end face of the rotating rod 452, a telescopic rod 455 is fixedly installed on the end face of the concave block 451, a hexagonal block 456 is fixedly installed at the other end of the telescopic rod 455, the stirring rod 453 is rotatably connected inside the concave block 451, one end of the rotating rod 452 penetrates through the concave block 451 and extends to the outside of the concave block 451, the hexagonal block 456 and the hexagonal groove 454 are adaptively clamped. An operator can push the telescopic rod 455 to shorten and drive the hexagonal block 456 to be clamped inside the hexagonal groove 454. At this time, the rotating rod 452 cannot continue to rotate, that is, at this time the rotating rod 452 stirs the mineral oil inside the cold extraction tank 1 at the current position.
[0030] Refer to Figure 2, the blocking component 3 includes vertical grooves 31 opened on the left and right sides of the inner wall of the cold extraction tank 1. A vertical rod 32 is fixedly installed inside the vertical groove 31. A slider 33 is slidably connected to the surface of the vertical rod 32. One end of the slider 33 close to the center of the cold extraction tank 1 is fixedly installed with a baffle 34. The slider 33 is slidably connected inside the vertical groove 31. The height of the top of the baffle 34 gradually decreases from the center of the cold extraction tank 1 towards the edge. The impurities precipitated inside the cold extraction tank 1 will fall on the surface of the baffle 34. At this time, it slides down on the surface of the baffle 34 to the bottom of the cold extraction tank 1. Concave holes 35 are opened on the surface of the baffle 34. A blocking block 36 is clamped at the top of the vertical groove 31. A pressure spring 37 is fixedly installed at the bottom end of the slider 33.
[0031] Working principle: After the operator pours the mineral oil into the cold extraction tank 1, at this time, rotate the stirring rod 453 so that the highest point of the stirring rod 453 rotates below the oil surface. Then the operator pushes the telescopic rod 455 to shorten, so that the telescopic rod 455 drives the fixedly connected hexagonal block 456 to be clamped inside the hexagonal groove 454. At this time, the rotating rod 452 cannot rotate continuously, that is, the stirring rod 453 cannot rotate continuously at this time. Therefore, the highest position of the stirring rod 453 is determined. Then the operator fixes the top end of the steel cable 23 to the suspension point of the elevator. Then place the hardware in the inner part of the storage frame 21. At this time, drive the elevator to drive the storage frame 21 to move downward until the storage frame 21 gradually moves downward into the cold extraction tank 1. At this time, the hardware inside the storage frame 21 gradually enters below the oil surface;
[0032] During the process of the storage frame 21 moving downward, at this time, the storage frame 21 presses down the top rod 47 under the action of its own gravity. At this time, the top rod 47 is pressed down into the inner part of the rotating tube 42. At this time, the top rod 47 will compress the elastic rod 46 and drive the convex rod 48 to move downward. Since the convex rod 48 slides inside the spiral groove 44, when the convex rod 48 moves downward, it will push the rotating tube 42 to rotate. At this time, the rotating tube 42 will drive the fixedly connected concave block 451 to rotate, that is, at this time, the concave block 451 will drive the stirring rod 453 to rotate inside the cold extraction tank 1. At this time, the stirring rod 453 stirs the mineral oil inside the cold extraction tank 1. Since the temperature of the mineral oil near the hardware inside the storage frame 21 inside the cold extraction tank 1 is relatively high, the rotating stirring rod 453 stirs the mineral oil to make the oil temperature evenly distributed.
[0033] During the cold extraction of the hardware, the impurities falling off the surface of the hardware will fall into the cold extraction tank 1. Then the impurities will fall to the bottom of the cold extraction tank 1 on the surface of the baffle 34. Then as the stirring rod 453 continues to stir the mineral oil, the vortex flow generated at this time may cause the impurities to move upward during the process of moving towards the center of the cold extraction tank 1. At this time, the baffle 34 will block the upward moving impurities to prevent the upward moving impurities from contacting the hardware again, which will affect the cooling effect of the hardware and avoid causing unevenness on the surface of the hardware.
[0034] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification is only to illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements fall within the scope of the present utility model claimed.
