Description

Technical Field

[0001] The present invention relates to the technical field of metal heat treatment, and particularly to a stirring tool for a heat treatment quenching pool. Background Technique

[0002] Quenching refers to a metal heat treatment process in which a metal workpiece is heated to an appropriate temperature and held for a period of time, and then immediately immersed in a quenching medium for rapid cooling. After quenching, the hardness and wear resistance of the metal workpiece are greatly improved. The existing quenching process generally requires the use of a quenching pool. During the specific quenching process, a traveling crane suspends a high-temperature casting (the casting is placed in a tray) through a sling and places the casting in the quenching pool for cooling. However, since the temperature of the casting is very high, when the casting is placed inside the quenching pool, the water in the quenching pool will be quickly heated. And when the hot water accumulates around the casting, the quenching effect will be unsatisfactory. Therefore, during the actual operation, a stirring tool needs to be installed in the quenching pool so that cold water can continuously impact the casting, so as to maximize the quenching effect.

[0003] In the prior art, the quenching stirring tool is usually arranged on both sides inside the quenching pool. The quenching stirring tool can pump the water at the bottom of the quenching pool and quickly spray it onto the casting, thereby preventing the hot water from accumulating around the casting and improving the quenching effect. However, the cold water outlets of the existing quenching stirring tools are relatively concentrated. When the size of the casting is large, the quenching stirring tool can only make the cold water impact a part of the area of the casting all the time, which leads to uneven heat distribution around the casting and indirectly results in an unsatisfactory quenching effect, making the hardness deviation of the casting large and unable to meet the performance requirements of the enterprise for the casting. In addition, if the cold water impact range of the quenching stirring tool is expanded, when the size of the casting is small, or when a large-size casting is just immersed in the quenching pool, it will also cause waste of cold water impact. For this reason, we have proposed a stirring tool for a heat treatment quenching pool to well solve the above drawbacks. Summary of the Invention

[0004] The purpose of the present invention is to provide a stirring tool for a heat treatment quenching pool to solve the problems raised in the above background technique.

[0005] The present invention is achieved through the following technical solutions:

The diversion pipes are in a shape and symmetrically distributed on both sides inside the quenching pool. A water pumping component is provided at the bottom end of the diversion pipes. Driving components corresponding to the water pumping components one by one are arranged on the left and right sides at the top of the quenching pool to drive the water pumping component to pump water into the diversion pipes. It further includes: a jet mechanism corresponding to the diversion pipes one by one. The jet mechanism includes a mouth part, a sealing plate and a water outlet pipe. The mouth part is connected to the outlet end at the top of the diversion pipe. The sealing plate is fixedly connected to the inner side of the mouth part. The number of the water outlet pipes is several and they are evenly distributed on the sealing plate. A plurality of water outlet trays are arranged outside the mouth part. Among them, one water outlet tray at the uppermost position is fixedly connected to the mouth part, and the other water outlet trays are all hinged to the mouth part. A jet nozzle corresponding to the water outlet pipe one by one is arranged at one end of the water outlet tray facing away from the diversion pipe. The jet nozzles are all connected to the corresponding water outlet pipes through hoses; an elastic member is also connected between two adjacent water outlet trays. When the elastic member is in a natural state, several water outlet trays all maintain a horizontal state; and a pulling mechanism is located at the middle position inside the quenching pool and is used to drive several water outlet trays to gradually unfold as the casting descends.

[0009] Optionally, a flange is provided at one end of the mouth part facing the diversion pipe, and the flange is connected to the outlet end at the top of the diversion pipe.

[0010] Optionally, the water outlet tray is trapezoidal, and the short side of the water outlet tray is connected to the mouth part. Pulling columns are arranged on the outer side walls of the water outlet trays; the elastic member is a tension spring, and both ends of the tension spring are respectively hung on the pulling columns on two adjacent water outlet trays.

[0011] Optionally, the pulling mechanism includes a perforated plate and telescopic parts movably arranged on the left and right sides of the perforated plate. Hinge seats are arranged on the top surfaces of the two telescopic parts, and the hinge seats are hinged to one water outlet tray at the lowermost position.

[0012] Optionally, hidden cavities are provided at both the left and right ends of the porous plate. One end of the telescopic part is movably inserted into the hidden cavity, and an elastic rope is further arranged on the bottom surface of the telescopic part. The other end of the elastic rope is connected to the bottom surface of the porous plate. In the natural state, the elastic rope is in a stretched state.

[0013] Optionally, the water pumping assembly includes a cylinder part and water pumping blades. The cylinder part is connected to the bottom end of the diversion pipe, and the water pumping blades are rotatably connected to the inner side of the cylinder part.

[0015] Compared with the prior art, the present invention provides a stirring tool for a heat treatment quenching pool, having the following beneficial effects:

[0016] 1. The jet mechanism in the present invention includes a plurality of water outlet trays that can be deployed or retracted, that is, the cold water impact range of the jet mechanism can dynamically change according to the size of the casting.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment: Please refer to Figures 1 - 7, A stirring tool for a heat treatment quenching pool, which includes flow guide pipes 200 located on the left and right sides inside the quenching pool 100. The flow guide pipes 200 are in a 7-shaped configuration and are symmetrically distributed on both sides inside the quenching pool 100. Specifically, the flow guide pipes 200 can be fixed in the quenching pool 100 through tools such as pipe clamps. A water pumping assembly 300 is provided at the bottom end of the flow guide pipe 200. Driving assemblies 400 corresponding to the water pumping assembly 300 one by one are provided on the left and right sides at the top of the quenching pool 100 to drive the water pumping assembly 300 to pump water into the flow guide pipe 200. Among them, the water pumping assembly 300 includes a cylinder part 301 and water pumping blades 302. The cylinder part 301 is connected to the bottom end of the flow guide pipe 200, and the water pumping blades 302 are rotatably connected to the inside of the cylinder part 301; the driving assembly 400 includes a mounting frame 401, a driving motor 402, a driving pulley 403, a driven pulley 404, and a transmission shaft 405. The mounting frame 401 is fixedly installed on the top of the quenching pool 100, the driving motor 402 is fixedly installed inside the mounting frame 401, the driving pulley 403 and the driven pulley 404 are both rotatably connected to the top of the mounting frame 401, and the two are driven by a belt. The output shaft of the driving motor 402 is coaxially connected to the driving pulley 403, and both ends of the transmission shaft 405 are coaxially connected to the driven pulley 404 and the water pumping blades 302 respectively; specifically, a limiting tube sleeve 201 is provided through the top of the flow guide pipe 200, the transmission shaft 405 movably passes through the limiting tube sleeve 201 and is inserted into the flow guide pipe 200. The driving motor 402 drives the water pumping blades 302 to rotate through the transmission shaft 405, so that the cold water at the bottom of the quenching pool 100 can be pumped into the flow guide pipe 200.

[0029] This embodiment further includes a jet mechanism 500. The jet mechanism 500 corresponds to the flow guide pipe 200 one by one. The jet mechanism 500 includes a mouth part 501, a sealing plate 502, and a water outlet pipe 503. The mouth part 501 is connected to the outlet end at the top of the flow guide pipe 200. Specifically, a flange plate 509 is provided at one end of the mouth part 501 facing the flow guide pipe 200, and the flange plate 509 is connected to the outlet end at the top of the flow guide pipe 200, and the mouth part 501 is square. The sealing plate 502 is fixedly connected to the inside of the mouth part 501. The number of water outlet pipes 503 is several and they are evenly distributed on the sealing plate 502, that is, the water outlet pipes 503 communicate with the inside of the flow guide pipe 200; a plurality of water outlet trays 504 are provided outside the mouth part 501. Among them, the uppermost water outlet tray 504 is fixedly connected to the mouth part 501, and the other water outlet trays 504 are all hinged to the mouth part 501, that is, the other water outlet trays 504 can all rotate around the mouth part 501 to adjust the inclination angle. A jet nozzle 505 corresponding to the water outlet pipe 503 one by one is provided at one end of the water outlet tray 504 facing away from the flow guide pipe 200. The jet nozzles 505 are all connected to the corresponding water outlet pipes 503 through hoses 506; therefore, the cold water entering the flow guide pipe 200 will be ejected from the water outlet pipes 503 and ejected from the jet nozzles 505 after passing through the hoses 506.

[0030] On the basis of the above embodiments, an elastic member 507 is further connected between two adjacent water outlet trays 504. When the elastic member 507 is in a natural state, several water outlet trays 504 are all kept in a horizontal state; specifically, the water outlet tray 504 is trapezoidal, and the short side of the water outlet tray 504 is connected to the mouth 501. Pulling columns 510 are provided on the outer side walls of the water outlet trays 504. Moreover, the elastic member 507 is a tension spring, and the two ends of the tension spring are respectively hung on the pulling columns 510 on two adjacent water outlet trays 504. As Figure 3 shown, that is, in the initial state of this embodiment, each water outlet tray 504 is kept horizontal; in addition, the jet nozzle 505 on the uppermost water outlet tray 504 is horizontally arranged, and the jet nozzles 505 on other water outlet trays 504 are all inclined upward, as Figure 3 shown. Since several jet nozzles 505 are all inclined upward, in the initial state, the cold water sprayed by the jet nozzles 505 also concentrates on the upper part of the quenching pool. That is, it is beneficial to adapt to small-sized castings, or when a large-sized casting just submerges into the water, since all the cold water sprayed by the jet nozzles 505 is directed at the casting, it also helps to improve the quenching effect.

[0031] It is worth mentioning that a contact portion 508 is inclined downward on the bottom surface of the mouth 501, and the angle between the contact portion 508 and the horizontal plane is not less than 30° and not greater than 40°; the function of setting the contact portion 508 is to prevent the water outlet tray 504 from unfolding excessively, so as to prevent the elastic member 507 from being damaged due to excessive pulling amplitude; another point is that the angle between the contact portion 508 and the horizontal plane is not greater than the angle between the jet nozzle 505 on the lowermost water outlet tray 504 and the horizontal plane. That is, when the lowermost water outlet tray 504 contacts the contact portion 508, as Figure 2 shown, at this time the jet nozzle 505 will not incline downward either.

[0032] This embodiment further includes a pulling mechanism 600, which is located at the middle position inside the quenching pool 100 and is used to drive a plurality of water outlet trays 504 to gradually unfold as the casting descends; specifically, the pulling mechanism 600 includes a perforated plate 601 and telescopic parts 602 movably arranged on the left and right sides of the perforated plate 601. The perforated plate 601 is a thin metal plate, and a plurality of through holes are formed on its surface. Hinge seats 603 are arranged on the top surfaces of both telescopic parts 602, and the hinge seats 603 are hinged to the lowermost water outlet tray 504; in addition, hidden cavities 604 are formed at both the left and right ends of the perforated plate 601, and one end of the telescopic part 602 is movably inserted into the hidden cavity 604. An elastic rope 605 is further arranged on the bottom surface of the telescopic part 602, and the other end of the elastic rope 605 is connected to the bottom surface of the perforated plate 601; in the natural state, the elastic rope 605 is in a stretched state, that is, the elastic rope 605 has a tendency to pull the telescopic part 602 into the hidden cavity 604. Specifically, during the use process, when the tray carrying the casting enters the water and contacts the perforated plate 601, it will push the perforated plate 601 downward, so that a plurality of water outlet trays 504 can gradually unfold. At the same time, since the water outlet tray 504 has a maximum unfolding amplitude, the pulling mechanism 600 also has a maximum descending amplitude. Specifically, during the implementation process, the tray carrying the casting must never exceed the maximum descending amplitude of the pulling mechanism 600, otherwise it will cause damage to the jet mechanism 500 and the pulling mechanism 600.

[0033] In addition, it is worth mentioning that the bottom of the quenching pool 100 in this embodiment has a water inlet, and the top of the quenching pool 100 has a drain outlet. Specifically, during the use process, the water inlet and the drain outlet are opened at the same time. On the one hand, it can ensure that there is always a large amount of cold water at the bottom of the quenching pool 100, and on the other hand, it can timely drain the hot water heated by the casting at the top of the quenching pool 100.

[0034] In summary, during the specific use of this embodiment, first, the traveling crane suspends the high-temperature casting by means of a steel cable and a material tray, and slowly immerses the casting into the quenching pool 100; at this time, the driving assembly 400 drives the water pumping assembly 300 to work, and the water pumping assembly 300 pumps the cold water at the bottom of the quenching pool 100 into the diversion pipe 200. The cold water entering the diversion pipe 200 then passes through the water outlet pipe 503 and the hose 506 and finally sprays out from the jet nozzle 505; in the initial state, since each water outlet tray 504 remains horizontal and a number of jet nozzles 505 are also inclined upward, therefore, the cold water sprayed out from the jet nozzle 505 at this time will all impact the surface of the high-temperature casting; as the casting gradually descends, and the material tray will push the pulling mechanism 600 to descend, thereby driving each water outlet tray 504 to gradually unfold, so the spraying range of the cold water of the jet mechanism 500 also gradually expands to adapt to castings of various sizes. In addition, since the casting in this embodiment is always located above the pulling mechanism 600, the water inlet of the quenching pool 100 is at the bottom, and the drain outlet is at the top, therefore, the pulling mechanism 600 also has the effect of preventing the cold water and hot water inside the quenching pool 100 from mixing with each other, and helps the drain outlet quickly discharge the hot water, thereby contributing to improving the quenching effect of the casting.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
