Description

Technical Field

[0001] The invention relates to the technical field of quenching oil tanks, in particular to a downward pressure stirring quenching oil tank. Background Art

[0002] During the processing of forgings, the forgings need to be placed in a quenching oil tank for quenching. The forgings obtain the required hardness, strength and toughness by rapid cooling. During the quenching process, the temperature uniformity of the quenching oil has a crucial influence on the quenching effect. Traditional quenching oil tanks usually use a stirrer in the middle of the oil tank to balance the oil temperature, but this method still causes differences in oil temperature at different positions in the oil tank, thereby affecting the quenching effect of the forgings and making the performance of the forgings uneven. And when quenching the forgings, the operators often use tools to clamp the forgings for quenching. In this way, the operators are not only easily scalded by the splashing oil, but also inhale the smoke and harmful substances released during the quenching process of the forgings. At the same time, these smoke and harmful substances will also diffuse into the air to pollute the environment. Therefore, a new type of quenching oil tank is needed. Summary of the invention

[0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a downward pressure stirring quenching oil tank, which can maintain the oil temperature at various places in the oil tank balanced, ensure the quenching effect of forgings, and prevent the quenching smoke from spreading, thereby avoiding damage to workers' health and environmental pollution.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-7 A downward pressure stirring quenching oil tank comprises a base 1, an oil tank 2 is arranged on the base 1, a U-shaped cover 3 is fixedly connected to the oil tank 2, an inner tank 21 is arranged at the bottom of the oil tank 2 through a supporting foot, a bearing mechanism 4 is arranged at the bottom of the oil tank 2, a stirring mechanism 5 is arranged on the U-shaped cover 3, the bearing mechanism 4 places the quenched part in the oil tank 2 for quenching, and after the quenching is completed, it is stirred by the stirring mechanism 5, so that the quenching oil in the oil tank 2 enters the inner tank 21 for temperature exchange.

[0018] After the forging is produced, the operator needs to quench the forging. Before putting the forging into the oil tank 2, the operator controls the stirring mechanism 5 to stir the oil in the oil tank 2 so that the oil in the oil tank 2 flows into the inner tank 21. Then, the operator controls the carrying mechanism 4 to transport the oil in the inner tank 21 out of the oil surface and pour it to the outside of the inner tank 21, so that the oil in the oil tank 2 flows from the outside of the inner tank 21 to the inner tank 21, and the oil in the inner tank 21 enters the outside of the inner tank 21. This makes the oil temperature in each place in the oil tank 2 balanced. The operator then controls the oil in the oil tank 2 to be quenched. The forgings are placed in the supporting mechanism 4, which brings the forgings into the oil tank 2 for quenching. During quenching, the stirring mechanism 5 and the U-shaped cover 3 cooperate to prevent the smoke generated by quenching from spreading out and polluting the environment. Finally, after quenching, the supporting mechanism 4 releases the forgings. The oil in the oil tank 2 is once again subjected to an oil temperature balancing operation under the cooperation of the supporting mechanism 4 and the stirring mechanism 5, ensuring that when each forging is quenched, the oil temperature in each place in the oil tank 2 is balanced, thereby ensuring the quenching effect of the forgings.

[0019] In some embodiments, an air outlet 31 is provided on the U-shaped cover 3, and an exhaust pipe 6 is installed on the air outlet 31. When the forging is placed in the oil tank 2 for quenching, the smoke generated by quenching will be extracted from the air outlet 31 along the exhaust pipe 6 by the exhaust pump on the exhaust pipe 6 and centrally processed to prevent the smoke from spreading throughout the factory building and affecting the health of workers, and to prevent the emission of polluted air directly into the atmosphere.

[0020] In some embodiments, the supporting mechanism 4 includes four electric push rods 41, and the four electric push rods 41 are divided into two groups. A supporting frame 42 is commonly installed on the telescopic parts of the two groups of electric push rods 41. A rotating shaft 46 is fixedly connected to the middle of the bottom of the supporting frame 42, and a first rotating plate 43 and a second rotating plate 44 are rotatably connected to the rotating shaft 46. The ends of the first rotating plate 43 and the second rotating plate 44 are fixedly connected to the supporting frame 42 with a tension spring 45. A plurality of oil leakage holes 421 are opened at the bottom of the supporting frame 42, and the four electric push rods 41 are connected to the bottom of the oil tank 2. Grooves 32 are provided on both sides of the U-shaped cover 3, and the two groups of electric push rods 41 are respectively located in the grooves 32.

[0021] In some embodiments, the stirring mechanism 5 includes two groups of cylinders 51, which are respectively installed on both sides of the U-shaped cover 3, and each of the telescopic parts of the two groups of cylinders 51 is installed with a connecting plate 52. Four baffles 53 are slidably connected between the two sides of the oil tank 2 and the two sides of the U-shaped cover 3. The four baffles 53 are divided into two groups, and each group of baffles 53 is fixedly connected to a connecting plate 52. A rack 55 is provided on a side wall of each baffle 53 close to the oil tank 2. Four agitators 58 are rotatably connected to the U-shaped cover 3, and each agitator 58 A second flat gear 57 is fixedly connected to each rack 55, a first flat gear 56 is connected between each rack 55 and each second flat gear 57, each first flat gear 56 is rotatably connected to the U-shaped cover 3, a protective sleeve 59 is provided on the outside of each agitator 58, each protective sleeve 59 is fixedly connected to the inner groove 21, the distance between the protective sleeve 59 and the bottom of the oil groove 2 is consistent with the distance between the inner groove 21 and the bottom of the oil groove 2, a scraper rod 54 is installed on the opposite sides of the two sets of baffles 53, and a shift bar is provided at the bottom of the scraper rod 54.

[0022] Working principle: After forging, the forging needs to be put into the oil tank 2 for quenching. At this time, the operator controls the two groups of cylinders 51 to work. The two groups of cylinders 51 extend and drive a group of baffles 53 to move through the connecting plate 52, so that the two groups of baffles 53 move back to back and open, exposing the oil tank 2 to the operator's eyes. Figure 1Taking the set of baffles 53 on the right side as an example, when the two baffles 53 move to the right, the racks 55 on the top of the two baffles 53 respectively drive a first flat gear 56 to rotate, and then each first flat gear 56 is linked to the second flat gear 57 to rotate, and then each second flat gear 57 drives the agitator 58 to stir. The agitator 58 stirs in the protective sleeve 59, so that the oil in the protective sleeve 59 is in a flowing state, flows downward in the protective sleeve 59, and enters the inner tank 21 through the gap between the protective sleeve 59 and the inner tank 21 and the bottom of the oil tank 2. At the same time, the two baffles 53 jointly drive the scraper rod 54 to the right The cylinder 51 moves until it is blocked by the protective sleeve 59, giving a blocked signal to the cylinder 51, so that the cylinder 51 no longer extends. Similarly, the four agitators 58 stir the oil in the protective sleeve 59, so that the oil enters the inner tank 21 from four directions, realizing the flow exchange of the oil. Then the operator controls the four electric push rods 41 to extend and push the bearing frame 42, the first rotating plate 43 and the second rotating plate 44 to move upward. At this time, the bearing frame 42 is loaded with oil. After the bearing frame 42 moves out of the oil surface, it continues to move upward for a distance, and then the first rotating plate 43 and the second rotating plate 44 are respectively in contact with a scraper 54. The first rotating plate 43 and the second rotating plate 44 are deflected with the rotating shaft 46 as the axis, so that the oil in the bearing frame 42 flows out from the oil leakage hole 421 to the two sides of the inner tank 21, so that the oil in the inner tank 21 flows to the two sides of the inner tank 21, and the oil on the two sides of the original inner tank 21 enters the inner tank 21, that is, the oil exchange is realized, so that the oil temperature in the oil tank 2 is mixed once, and the oil temperature in the oil tank 2 is balanced. Then the operator places the forging in the bearing frame 42, and then controls the electric push rod 41 to contract and drive the bearing frame 42 to move downward. As the bearing frame 42 carries the forging downward into the inner tank 21, the oil temperature in the oil tank 2 is balanced. Inner groove 21, the forging begins to quench, and the first rotating plate 43 and the second rotating plate 44 are also reset by the elastic force of the tension spring 45, and are again close to the bottom of the bearing frame 42, so that the bearing frame 42 can be filled with oil. After the quenching is completed, the above action is repeated to push the bearing frame 42 out of the oil surface, and the operator can take away the forging that has completed quenching and replace it with another forging that needs to be quenched. At this time, the oil in the oil tank 2 is exchanged once, and the oil temperature is also balanced, so that the oil temperature of each place in the oil tank 2 is the same before quenching of each forging, ensuring that the quenching effect of the forging will not be affected by the different temperatures in various places in the oil tank 2.

[0023] In some embodiments, the top of the first rotating plate 43 and the second rotating plate 44 are attached to the bottom of the supporting frame 42 .

[0024] It can ensure that the first rotating plate 43 and the second rotating plate 44 are both in close contact with the bottom of the supporting frame 42, so that the supporting frame 42 can load a certain amount of oil and move out of the range of the inner tank 21, laying the foundation for maintaining the uniform temperature in the oil tank 2 later.

[0025] In some embodiments, the tension spring 45 is initially in a tensioned state.

[0026] The tension spring 45 is initially in a tensioned state, which can enhance the contact degree between the first rotating plate 43 and the second rotating plate 44 and the bottom of the supporting frame 42, and prevent the supporting frame 42 from rotating before contacting the scraper rod 54, resulting in failure to load a certain amount of oil.

[0027] In some embodiments, a plurality of the shift bars are provided, and the plurality of shift bars are inclined and spaced apart.

[0028] The inclined shift bar can break the calmness of the oil surface, thereby preventing the oil in the oil tank 2 from splashing when the carrying frame 42 moves out of the oil surface, thereby preventing the safety of the operator from being endangered.

[0029] In some embodiments, a straight groove 510 is formed at the bottom of each baffle plate 53 , and a shift plate 511 is slidably connected to the straight groove 510 , and the shift plate 511 is located between the protective sleeve 59 and the side of the oil tank 2 .

[0030] When the operator controls the two sets of baffles 53 to move back and forth to open, as shown in the attached Figure 1 , the end of the straight groove 510 on the front and rear baffles 53 of the two sets of baffles 53 close to the scraper rod 54 will gradually contact with the paddle 511 as the baffle 53 moves, and then the baffle 53 continues to move, so that the straight groove 510 moves with the paddle 511 to the edge of the oil groove 2, and while moving, the oil in the original position is pushed to the edge of the oil groove 2 until the paddle 511 is driven to the edge of the oil groove 2. Similarly, when the operator controls the two sets of baffles 53 to move toward each other for closing, the two paddles 511 will pry the oil in the oil groove 2 toward the inner groove 21 until the paddle 511 is blocked by the protective cover 59, and then the baffle 53 continues to move, and finally the two baffles 53 contact and close the entire top of the oil groove 2, and the back and forth movement of the two paddles 511 stirs the oil in the oil groove 2, so that the oil temperature is mixed and balanced.

[0031] In some embodiments, the distances between the paddle 511 and the protective sleeve 59 and the bottom of the oil tank 2 are the same.

[0032] When the two paddles 511 are respectively driven by a baffle 53 to move, the two paddles 511 paddle the oil in the oil tank 2. Since the paddles 511 and the protective sleeve 59 are at the same distance from the bottom of the oil tank 2, and the agitators 58 in the two protective sleeves 59 stir the oil to guide it to the bottom of the oil tank 2, the oil will enter the inner tank 21 through the gap between the inner tank 21 and the bottom of the oil tank 2, achieving the effect of guiding the flow of oil, which is equivalent to stirring the oil in the entire oil tank 2, so that the oil temperature in the entire oil tank 2 is evenly mixed.

[0033] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
