[0002] Auto parts refer to accessories on cars, including gears, shafts, cranks, connecting rods and other workpieces. In the production process of auto parts, one of the production processes is to heat some auto parts to a critical temperature Ac3 or above Ac1, keep them warm for a period of time to make them fully or partially austenitized, and then cool them to below MS at a cooling rate greater than the critical cooling rate to transform them into martensite (or bainite), which effectively improves the hardness and strength of auto parts.

[0003] In the existing quenching device for automobile parts, the user usually immerses multiple high-temperature workpieces into a cooling medium through a crane. The cooling medium in the quenching device is generally water or oil. When the high-temperature workpiece is immersed in the water tank, the water temperature rises accordingly. The heated water is cooled by the circulating water device and put into use again. However, due to the vaporization of water around the parts during quenching, an isolation layer is generated, which reduces the contact area between the overlapping high-temperature workpieces and the water, thereby reducing the cooling rate of the high-temperature workpieces, resulting in low quenching efficiency of automobile parts.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a quenching device for automobile parts is provided, in order to achieve a more practical purpose. Utility Model Content

[0026] Example:

[0027] As attached Figure 1 To Attachment Figure 4 As shown:

[0028] The utility model provides a quenching device for automobile parts, comprising a box body 1, wherein two chambers are distributed in the upper and lower parts of the box body 1, namely a quenching chamber 4 and a water storage chamber 5, four first water pipes 15 are vertically arranged at the four corners of the quenching chamber 4, and the bottoms of the four first water pipes 15 are connected together by second water pipes 16 to form a frame, and the functions of the first water pipes 15 and the second water pipes 16 are to facilitate the circulation of cooled water to flow into the quenching chamber 4 through the first water pipes 15 and the second water pipes 16, so as to facilitate the water after the cooling cycle to exchange heat with the water in the quenching chamber 4, a cooling basket 3 is arranged in the frame, and the cooling basket 3 is a structure of multiple holes, so that the high-temperature components in the cooling basket 3 are contacted with water for cooling, the quenching chamber 4 and the water storage chamber 5 are connected through a third water pipe 6, a countercurrent closed cooling tower 2 is installed on one side of the box body 1, and a water inlet pipe 8 and a drain pipe 9 are respectively connected between the countercurrent closed cooling tower 2 and the box body 1, and one end of the water inlet pipe 8 passes through the quenching The chamber 4 is connected to one end of one of the second water pipes 16, and one end of the drain pipe 9 is passed through the water storage chamber 5. Since the high-temperature workpiece is placed in the cooling basket 3, the water in the quenching chamber 4 becomes hotter as the high-temperature workpiece, and the water with higher temperature flows into the water storage chamber 5 through the third water pipe 6 at the bottom of the quenching chamber 4. The countercurrent closed cooling tower 2 uses a water pump to extract the raised temperature water from the water storage chamber 5 through the drain pipe 9, and the raised temperature water is injected from the top of the tower, and then flows downward along the countercurrent heat exchange surface inside the tower. At the same time, air enters from the bottom of the tower to exchange heat with the raised temperature water, taking away the heat in the raised temperature water. The cooled water passes through the circulating pump through the water inlet pipe 8 and is discharged from the first water pipe 15 to the quenching chamber 4 through the second water pipe 16. The cooled water exchanges heat with the water in the quenching chamber 4, so that the water temperature in the quenching chamber 4 is appropriate; the countercurrent closed cooling tower 2 is a prior art and will not be described in detail in the present utility model.

[0029] like Figures 2 to 4As shown, both sides of the cooling basket 3 are connected to the inner wall of the quenching chamber 4 through a vibration assembly, and the vibration assembly includes an eccentric wheel 11 rotatably arranged in the quenching chamber 4, and the eccentric wheel 11 is rotatably connected to the inner side of the quenching chamber 4. Motors 10 are installed on both sides of the box body 1 located in the quenching chamber 4, and the driving shaft of the motor 10 passes through the quenching chamber 4 and is connected to the eccentric wheel 11. Slide grooves 14 are provided on both sides of the interior of the quenching chamber 4, and connecting blocks 13 are slidably arranged in the slide grooves 14. One end of the connecting block 13 is fixedly connected to both sides of the cooling basket 3, and the eccentric shaft on the eccentric wheel 11 is hinged with one end of a rocker 12, and the other end of the rocker 12 is rotatably connected to the bottom of the connecting block 13. When the motor 1 The eccentric wheel 11 is driven to move and drive one end of the rocker 12. Since the connecting block 13 can only slide linearly in the slide groove 14, the other end of the rocker 12 is rotatably connected to the connecting block 13. Then, when the eccentric wheel 11 rotates, the other end of the rocker 12 drives the connecting block 13 to slide up and down in the slide groove 14. The two sides of the cooling basket 3 are fixedly connected with the connecting blocks 13, so that when the two connecting blocks 13 slide up and down in the slide groove 14, the cooling basket 3 also swings up and down with the connecting blocks 13. The overlapping high-temperature workpieces in the cooling basket 3 swing up and down in the water in the quenching chamber 4 under the action of the vibration component, thereby increasing the contact area between the overlapping high-temperature workpieces and the water, thereby improving the quenching efficiency of automobile parts.

[0030] like Figure 2 As shown, a plurality of water outlet pipes 17 are vertically distributed on the pipe walls of the four first water pipes 15, and the cooled water is sprayed in opposite directions through the plurality of water outlet pipes 17, thereby realizing rapid cooling of the high-temperature workpiece during the quenching process. The water sprayed in opposite directions can provide more uniform and rapid heat exchange, helping to quickly cool the high-temperature workpiece.

[0031] like Figure 2 As shown, a valve 7 is provided on the third water pipe 6, and the axis of the valve 7 passes through the side wall of the water storage chamber 5 and is connected to the hand wheel. When the water in the third water pipe 6 passes through the valve core in the valve 7, the water pressure acts on the valve core, causing the valve core to move, thereby changing the opening of the channel of the third water pipe 6, and further changing the water flow and pressure. The user can rotate the valve 7 to change the position of the valve core to achieve flow regulation.

[0032] like Figures 2 to 3As shown, a filter plate 18 is arranged in the water storage chamber 5 under the bottom of the third water pipe 6. The arrangement of the filter plate 18 can conveniently filter impurities in the quenching process of the high-temperature workpiece in the quenching chamber 4, so as to avoid the countercurrent closed cooling tower 2 being damaged by impurities during the circulating cooling process. A holding basket 19 is arranged on one side of the water storage chamber 5. The holding basket 19 is detachably installed in the water storage chamber 5. The holding basket 19 is located on one side of the filter plate 18 and is flush with the filter plate 18. The holding basket 19 is flush with the water storage chamber 5. The two parts are connected, a scraper 21 is provided on one side of the top of the filter plate 18, and a cylinder 20 is installed on one side of the box body 1 on the water storage chamber 5. The piston rod of the cylinder 20 is connected to the scraper 21, and the cylinder 20 drives the piston rod to drive the scraper 21 on the filter plate 18 to push toward the receiving basket 19, so as to scrape out the impurities on the filter plate 18 to prevent the impurities from clogging the filter plate 18 and affecting the efficiency of the temperature water filtering and dripping. The scraped impurities fall into the receiving basket 19, which is convenient for the user to dump the impurities uniformly.

[0033] Among them, a fan is fixedly installed on one side of the top of the box 1. The fan uses the flow of wind to blow away the hot air generated by the high-temperature workpiece immersed in water, thereby reducing the temperature and preventing the hot air from affecting the user's field of vision when observing the quenching condition of the high-temperature workpiece. The fan can also help water circulation, increase the cooling effect of the water, and improve the quenching efficiency.

[0034] When using:

[0035] The user immerses multiple high-temperature workpieces into the cooling basket 3 in the quenching chamber 4 through a crane. The two sides of the cooling basket 3 swing up and down in the slide 14 along with the two vibrating components, so that the contact area between the multiple overlapping high-temperature workpieces and the water is increased, thereby accelerating the quenching efficiency of the high-temperature workpieces. As the temperature of the high-temperature workpieces increases, the water in the quenching chamber 4 flows into the water storage chamber 5 through the third water pipe 6, and drips to the bottom of the water storage chamber 5 through the filter plate 18 in the water storage chamber 5, filtering the impurities generated during the quenching of the high-temperature workpieces. The cylinder 20 drives the piston rod to drive the scraper 21 to make reciprocating linear motion on the filter plate 18. The impurities on the filter plate 18 are pushed into the containing basket 19 by the scraper 21, and the filtered water enters the countercurrent closed cooling tower 2 through the drainage pipe 9 penetrated at the bottom of the water storage chamber 5 for circulating cooling treatment. The cooled water is transported from the water inlet pipe 8 to the first water pipe 15 and sprayed to the high-temperature workpiece through multiple water outlet pipes 17, which further improves the quenching efficiency of the high-temperature workpiece. The water in the drainage pipe 9 and the water inlet pipe 8 flows in and out, so that the water in the quenching chamber 4 is alternately hot and cold, and the water in the quenching chamber 4 maintains a suitable water temperature, which effectively realizes the rapid cooling of the high-temperature workpiece and improves the quenching efficiency of automobile parts.
