A heat treatment device for a hydraulic cylinder

Abstract

This utility model relates to the field of hydraulic cylinder heat treatment, specifically a heat treatment device for hydraulic cylinders, including a heating furnace body, a pulley hoisting equipment body, and a cooling water tank. This utility model utilizes the heating furnace body, pulley hoisting equipment body, cooling water tank, internal support clamping mechanism, and oil-water separation mechanism. The internal support clamping mechanism, in conjunction with the pulley hoisting equipment body, lifts hydraulic cylinders of different inner diameters and moves them into the cooling water tank for cooling and quenching.

This solves the problem that most hydraulic cylinder lifting and moving supports are fixed, which can cause the support to be incompatible if the hydraulic cylinder is too large or too small. Forced lifting may cause the hydraulic cylinder to fall, resulting in damage and threatening the safety of surrounding personnel.

[0003] When performing heat treatment on hydraulic cylinders, the heated hydraulic cylinders need to be placed in water for cooling and quenching. However, the support frame used to lift and move hydraulic cylinders is usually fixed. If the hydraulic cylinder is too large or too small, the support frame may not be suitable for lifting it. If it is forcibly lifted, the hydraulic cylinder may fall and be damaged, which may also threaten the lives of the surrounding workers. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the support frame for lifting and moving hydraulic cylinders is usually fixed. If the hydraulic cylinder is too large or too small, the support frame may not be suitable for lifting it. If it is forcibly lifted, the hydraulic cylinder may fall and be damaged, which may also threaten the life safety of the surrounding workers. This utility model proposes a heat treatment device for hydraulic cylinders.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a heat treatment device for hydraulic cylinders, including a heating furnace body, a pulley hoisting equipment body and a cooling water tank, wherein an internal support clamping mechanism is provided at the bottom of the pulley hoisting equipment body and an oil-water separation mechanism is provided on one side of the cooling water tank.

[0006] The internal support clamping mechanism includes a mounting column, the top of which is fixedly connected to the bottom of the pulley hoisting equipment body. A cylinder is fixedly connected to the inner cavity of the mounting column, and a fixing column is fixedly connected to the telescopic end of the cylinder. Eight first fixing blocks are fixedly connected to the surface of the mounting column. A first connecting rod is rotatably connected to the inner cavity of each first fixing block via a rotating shaft. A second fixing block is rotatably connected to the surface of each first connecting rod via a rotating shaft. A clamping block is fixedly connected to the surface of every two second fixing blocks. Four third fixing blocks are fixedly connected to the surface of the fixing column. A second connecting rod is rotatably connected to the inner cavity of each third fixing block via a rotating shaft. A fourth fixing block is rotatably connected to the surface of each second connecting rod via a rotating shaft. The inner side of each fourth fixing block is fixedly connected to the surface of a clamping block.

[0007] Preferably, each of the clamping blocks has an arc-shaped groove on its surface, and the number of the arc-shaped grooves is several.

[0008] Preferably, the oil-water separation mechanism includes a separation chamber located on one side of a cooling water tank. A first water pump is fixedly connected to the surface of the cooling water tank. The input end of the first water pump is fixedly connected to the inner cavity of the cooling water tank, and the output end of the first water pump extends through the inner cavity of the separation chamber. A first baffle and a second baffle are fixedly connected to the inner cavity of the separation chamber. The height of the first baffle is lower than the height of the second baffle. An outlet pipe is fixedly connected to the surface of the separation chamber.

[0009] Preferably, a second water pump is fixedly connected to the surface of the separation chamber, the input end of the second water pump extends into the inner cavity of the separation chamber, and a guide pipe is fixedly connected to the output end of the second water pump, with one end of the guide pipe located at the top of the cooling water tank.

[0010] Preferably, the surface of the first baffle is provided with a first water guide groove, and the surface of the second baffle is provided with a second water guide groove, the position of the second water guide groove being lower than that of the first water guide groove.

[0013] Preferably, a scraper plate is fixedly connected to the top of the scraper bar, and the scraper plate is arranged in an arc shape.

[0014] Compared with existing technologies, this utility model uses a heating furnace body, a pulley hoisting equipment body, a cooling water tank, an internal support clamping mechanism, and an oil-water separation mechanism. The internal support clamping mechanism, in conjunction with the pulley hoisting equipment body, lifts hydraulic cylinders of different inner diameters and moves them into the cooling water tank for cooling and quenching. Then, the oil-water separation mechanism separates the oil floating on the surface of the water in the cooling water tank, and finally discharges the floating oil and re-introduces the separated water into the cooling water tank. This solves the problem that the support frames for lifting and moving hydraulic cylinders are mostly fixed. If the hydraulic cylinder is too large or too small, the support frame may not be suitable for lifting it. If it is forcibly lifted, the hydraulic cylinder may fall and be damaged, which also threatens the life safety of the surrounding workers. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a heat treatment apparatus for hydraulic cylinders. (Refer to...) Figure 1 and Figure 5 A heat treatment device for hydraulic cylinders includes a heating furnace body 1, a pulley hoisting device body 2, and a cooling water tank 3. The bottom of the pulley hoisting device body 2 is provided with an internal support clamping mechanism 4, and one side of the cooling water tank 3 is provided with an oil-water separation mechanism 5. The heating furnace body 1 includes a heating furnace, a track, and a conveyor vehicle. The track is fixedly connected to the ground, and the rollers at the bottom of the conveyor vehicle slide on the surface of the track. The pulley hoisting device body 2 includes a guide rail and a pulley hoisting device. The guide rail is installed on a frame or ceiling.

[0025] The internal support clamping mechanism 4 includes a mounting column 401. The top of the mounting column 401 is fixedly connected to the bottom of the pulley hoisting equipment body 2. A cylinder 403 is fixedly connected to the inner cavity of the mounting column 401. A fixing column 407 is fixedly connected to the telescopic end of the cylinder 403. Eight first fixing blocks 404 are fixedly connected to the surface of the mounting column 401. The inner cavity of each first fixing block 404 is rotatably connected to a first connecting rod 405 via a rotating shaft. The surface of each first connecting rod 405 is rotatable via a rotating shaft. A second fixing block 406 is connected, and a clamping block 402 is fixedly connected to the surface of every two second fixing blocks 406. A third fixing block 409 is fixedly connected to the surface of the fixing post 407. There are four third fixing blocks 409. The inner cavity of each third fixing block 409 is rotatably connected to a second connecting rod 411 through a rotating shaft. The surface of each second connecting rod 411 is rotatably connected to a fourth fixing block 410 through a rotating shaft. The surface of each fourth fixing block 410 is fixedly connected to the inner side of a clamping block 402.

[0026] Reference Figure 3 Each clamping block 402 has an arc-shaped groove 408 on its surface. There are several arc-shaped grooves 408. By setting the arc-shaped grooves 408, the friction force of the clamping block 402 when clamping the inner diameter of the hydraulic cylinder is increased, thus increasing the stability of clamping the hydraulic cylinder.

[0027] Reference Figure 4The oil-water separation mechanism 5 includes a separation chamber 501, which is located on one side of the cooling water tank 3. A first water pump 502 is fixedly connected to the surface of the cooling water tank 3. The input end of the first water pump 502 is fixedly connected to the inner cavity of the cooling water tank 3, and the output end of the first water pump 502 extends into the inner cavity of the separation chamber 501. A first baffle 504 and a second baffle 506 are fixedly connected to the inner cavity of the separation chamber 501. The height of the first baffle 504 is lower than the height of the second baffle 506. An outlet pipe 505 is fixedly connected to the surface of the separation chamber 501. Through the cooperation of the separation chamber 501, the first water pump 502, the first baffle 504, the outlet pipe 505, and the second baffle 506, the first water pump 502 draws the oil-water mixture floating on the top of the inner cavity of the cooling water tank 3 into the inner cavity of the separation chamber 501. The first baffle 504 and the second baffle 506 separate the oil and water into layers. Finally, based on the principle that oil floats on the water surface, the oil will be discharged through the outlet pipe 505.

[0028] Reference Figure 4 A second water pump 508 is fixedly connected to the surface of the separation chamber 501. The input end of the second water pump 508 extends into the inner cavity of the separation chamber 501. A guide pipe 509 is fixedly connected to the output end of the second water pump 508. One end of the guide pipe 509 is located at the top of the cooling water tank 3. With the second water pump 508 and the guide pipe 509, when the second water pump 508 is working, the water at the bottom of the separation chamber 501 can be drawn out and transported back to the inner cavity of the cooling water tank 3 through the guide pipe 509.

[0029] Reference Figure 4 The surface of the first baffle 504 is provided with a first water guide groove 503, and the surface of the second baffle 506 is provided with a second water guide groove 507. The position of the second water guide groove 507 is lower than that of the first water guide groove 503. With the first water guide groove 503 and the second water guide groove 507 set up, since the position of the second water guide groove 507 is lower than that of the first water guide groove 503, when the oil-water mixture enters the position between the first baffle 504 and the second baffle 506, a large amount of oil will float to the top, a small amount of oil may enter the compartment on the right side separated by the second baffle 506 along with water, and will eventually be pumped away by the second water pump 508, while a large amount of oil will be discharged through the discharge pipe 505.

[0030] Reference Figure 5 A scraper 510 is movably connected to the inner cavity of the cooling water tank 3. A dovetail block 513 is fixedly connected to the surface of the scraper 510. The surface of the dovetail block 513 is movably connected to the inner cavity of the cooling water tank 3. By setting the scraper 510 and the dovetail block 513, the scraper 510 can be moved to push the oil sludge floating on the water surface at the top of the inner cavity of the cooling water tank 3, and finally push it to the direction of the first water pump 502, so that the first water pump 502 can extract it.

[0031] Reference Figure 5The inner side of the cooling water tank 3 is provided with dovetail grooves 512. There are two dovetail grooves 512. The inner cavity of each dovetail groove 512 is movably connected to the surface of a dovetail block 513. The dovetail grooves 512 guide the dovetail block 513 when it slides in the inner cavity of the cooling water tank 3, which indirectly improves the stability of the scraper strip 510 sliding in the inner cavity of the cooling water tank 3.

[0032] Reference Figure 5 A scraper plate 511 is fixedly connected to the top of the scraper bar 510. The scraper plate 511 is arc-shaped. Due to the arc-shaped structure of the scraper plate 511, when the scraper bar 510 pushes a lot of oil, the arc-shaped structure of the scraper plate 511 can prevent the oil from passing over the scraper bar 510, so that the oil can be smoothly pushed to the direction of the first water pump 502.

[0033] Working Principle: When heat treatment of a hydraulic cylinder is required, the object is first placed inside the heating furnace body 1 for heating. The heating furnace body 1 includes the heating furnace, rails, and a conveyor cart. The hydraulic cylinder is placed on the conveyor cart, and then the conveyor cart enters the heating furnace along the rails. The furnace door is closed for heating. After heating is complete, the furnace door is opened, and the hydraulic cylinder is lifted by the pulley hoisting device body 2. The pulley hoisting device body 2 includes guide rails and pulley hoisting devices. The guide rails are installed on a frame or ceiling. The heated hydraulic cylinder is then placed in the cooling water tank 3 for cooling and quenching. To accommodate the lifting of hydraulic cylinders with different inner diameters, the pulley hoisting device... The pulley hoist in the main body 2 moves the installation column 401 to the inside of the hydraulic cylinder. Then, the cylinder 403 starts working, and the extension end of the cylinder 403 drives the fixed column 407 to move downward. The fixed column 407 drives the third fixed block 409 to move downward. The third fixed block 409 drives the second connecting rod 411 to rotate. The second connecting rod 411 drives the fourth fixed block 410 to move outward, thereby driving the clamping block 402 to move outward. The clamping block 402 drives the second fixed block 406 to move. The second fixed block 406 drives the first connecting rod 405 to rotate on the surface of the first fixed block 404 until the clamping block 405 moves outward. The outer side of 02 is in close contact with the inner side of the hydraulic cylinder. At this time, the pulley hoist in the pulley hoisting equipment body 2 is lifted upward, and the heated hydraulic cylinder is placed into the inner cavity of the cooling water tank 3 with the help of the guide rail. It is cooled and quenched by the water in the inner cavity of the cooling water tank 3. When the water in the cooling water tank 3 is used, oil will float on the water surface, affecting the cooling effect on the hydraulic cylinder next time. Therefore, after use, the scraper bar 510 can be pulled, which drives the scraper plate 511 to move. At the same time, the dovetail block 513 slides in the inner cavity of the cooling water tank 3. The scraper bar 510 and the scraper plate 511 push the floating oil on the water surface. At the same time, the first water pump 502 starts working, sucking in the oil-water mixture pushed by scraper bar 510 and scraper plate 511 and drawing it into separation chamber 501. Based on the principle that oil floats on water, the oil sludge floats to the top of the inner cavity of separation chamber 501 and is blocked by the second baffle 506. The water flows through the first water guide channel 503 to the second water guide channel 507, which separates the right-side compartment. Finally, the second water pump 508 starts working, drawing water from the bottom separated by the second water guide channel 507 and sending it back to the inner cavity of cooling water tank 3 through guide pipe 509. The oil sludge at the top of the inner cavity of separation chamber 501 is discharged through outlet pipe 505.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
