Description

Technical Field

[0001] The present invention relates to the technical field of heat treatment of ring-shaped workpieces, and in particular to a ring forging quenching device and a quenching method. Background Art

[0002] Quenching of ring forgings can enhance the hardness by forming martensite inside the material through rapid cooling. High hardness makes ring forgings more resistant to wear and prolongs their service life. Quenching can also optimize the strength, toughness and fatigue properties of the material. Quenching requires heating the ring forgings to above the critical temperature (usually 850°C to 950°C) to ensure that the structure is completely austenitized. Maintain a certain time to make the temperature uniform and the structure fully transformed. Quickly immerse the ring forging in a cooling medium (such as water, oil or polymer solution). The cooling rate depends on the material and requirements. Tempering is performed after quenching to reduce internal stress, improve toughness and prevent brittle fracture.

[0003] The Chinese patent application publication number CN118480674A proposes a large ring forging quenching heat treatment equipment, which specifically includes: a bottom plate, the top of the bottom plate is fixedly connected to an arc-shaped vertical plate, the top of the arc-shaped vertical plate is fixedly connected to a top plate, the top of the top plate is fixedly connected to a heating cylinder, the bottom of the top plate is fixedly connected to a heat insulation plate, and the top of the bottom plate is fixedly connected to a cooling cylinder; the large ring forging quenching heat treatment equipment also includes: a heating mechanism for placing raw materials and heating the raw materials, the heating mechanism is fixedly connected to the inside of the heating cylinder, the heating mechanism includes an annular slide, the inside of the annular slide is slidably connected to a first telescopic rod, the top of the first telescopic rod is fixedly connected to a first adjustment plate, the outside of the first adjustment plate is fixedly connected to a bent rod, and the outside of the bent rod is fixedly connected to a rotating component.

[0004] The aforementioned ring forging quenching device integrates the heating mechanism and the cooling mechanism into a single unit. However, manual relocation of the ring forging and subsequent position adjustment are required. The heating and cooling functions are not truly integrated with the ring structure, and the device relies heavily on manual labor. Furthermore, due to the ring structure of the ring forging, movement and transfer are time-consuming and labor-intensive, resulting in insufficient intelligence. Furthermore, the device is open, resulting in insufficient heat preservation during heating operations, which affects the quenching effect of the ring forgings. During cooling operations, a large amount of high-temperature steam will overflow, posing a safety hazard. Summary of the Invention

[0005] In response to the problems existing in the background technology, a ring forging quenching device and quenching method are proposed.

DETAILED DESCRIPTION

[0030] Example 1, as Figure 1-Figure 3 As shown, the present invention provides a ring forging quenching device, comprising a quenching chamber 1, a heating assembly 3, a piston plate 4, a cleaning assembly 7, a position adjustment assembly 5, and a limit assembly 6. Within the quenching chamber 1, isolation plates 2 with circular isolation openings are positioned one above the other. A chamber door is provided in the front for the entry and exit of the ring forging. The internal space is divided from top to bottom by the isolation plates 2 into a heating chamber 102, an entry and exit chamber 101, and a cooling chamber 103. The cooling chamber 103 is filled with coolant. The entry and exit chamber 101 is located opposite the chamber door. The heating assembly 3 is located in the heating chamber 102 and achieves simultaneous heating of the outer and inner rings of the ring forging by providing a heating structure that matches the dimensions of the inner and outer rings of the ring forging. The piston plate 4 is located below the coolant in the cooling chamber 103 and, by moving up and down, drives the coolant in and out of the cooling chamber 103 and immerses the ring forging in the coolant. The cleaning assembly 7 is located behind the entry and exit chamber 101 and engages with the outer ring and one end of the ring forging. The position adjustment assembly 5 is located between the cleaning assembly 7 and the chamber door. The limiting component 6 is arranged on the position adjustment component 5, and the ring forging is suspended and limited by cooperating with the inner ring and the other side end of the ring forging. At the same time, on the one hand, the position adjustment component 5 drives the forward and backward movement and flipping to realize material loading and unloading and cleaning. On the other hand, the position adjustment component 5 drives the up and down movement and flipping, and extends into the upper and lower isolation ports respectively through the limiting component 6, so as to prompt the ring forging to enter the heating chamber 102 and the cooling chamber 103, and complete heating and cooling in a sealed environment.

[0031] like Figure 4-Figure 6 As shown, the position adjustment component 5 includes a lifting platform 503 driven by a driving structure 1 to move up and down between the two groups of isolation plates 2; a mounting rod 504 driven by a driving structure 2 to move back and forth between the box door and the cleaning component 7 is provided on the lifting platform 503; a mounting seat 505 is provided on the mounting rod 504; the mounting seat 505 is driven by a driving structure 3 to rotate to be opposite to the box door, the upper isolation port, the cleaning component 7 and the lower isolation port; the limiting component 6 is provided on the mounting seat 505.

[0032] It should be further explained that the driving structure 1 includes a motor 1, which drives the lead screw 1 502 to rotate between the two sets of isolation plates 2. The lifting platform 503 is connected to the lead screw 1 502 by a thread to achieve up and down movement.

[0033] It should be further explained that four groups of lead screws 502 are provided, which are respectively located on both sides of the two groups of lifting platforms 503.

[0034] It should be further explained that the second driving structure includes a second motor; the second motor drives the second screw 501 to rotate on the lifting platform 503; the mounting rod 504 is connected to the second screw 501 through a thread to achieve forward and backward movement.

[0035] It should be further explained that two groups of lifting platforms 503 are provided, located on both sides of the mounting seat 505, and mounting grooves 1 are provided on opposite ends of the two groups of lifting platforms 503; and the second screw 501 is rotatably provided in the mounting groove 1.

[0036] It should be further explained that the driving structure three is configured as a motor three located on the mounting seat 505 ; one end of the mounting rod 504 is connected to the main shaft of the motor three, and the other end is connected to the threaded connection screw 2 501 .

[0037] It should be further explained that the rod body of the mounting rod 504 is configured as an S-shaped structure.

[0038] Through the cooperation of drive structure 1, drive structure 2 and drive structure 3, the limit component 6 can move and flip forward and backward, up and down, and then switch its position to be opposite to the box door, upper isolation port, cleaning component 7 and lower isolation port, realizing continuous and efficient quenching.

[0039] like Figure 4-Figure 5 As shown, the limit assembly 6 is arranged at the center of the mounting seat 505; a circle of sealing ring groove 506 is arranged on the outer periphery of the mounting seat 505; sealing rings 507 are arranged on the inner and outer ring edges of the sealing ring groove 506, and an annular filter is arranged on the groove, and a negative pressure is formed in the groove by an air pump 508; the size of the sealing ring groove 506 is larger than the isolation port; the size of the limit assembly 6 is smaller than the isolation port; and a sealing door 201 is arranged on the isolation port.

[0040] When the stopper assembly 6 extends into the heating chamber 102 and the cooling chamber 103, the mounting base 505 abuts against the isolation plate 2, forming a seal. The mounting base 505 utilizes a unique design, with an S-shaped mounting rod 504 that extends the heat conduction path, maintaining a safe distance between the motor 3 and the high-temperature zone. Unlike conventional equipment that requires additional cooling systems for transmission components, this invention achieves natural heat dissipation through structural optimization.

[0041] In order to improve the sealing performance, the present invention sets up a dynamic air sealing system, which forms a negative pressure environment through the sealing ring groove 506 and the vacuum pump 508. The double sealing ring 507 design (one group for each inner and outer ring edges) forms a multiple sealing barrier. At the same time, the annular filter prevents particulate matter from damaging the sealing interface. By heating the ring forging in a sealed environment, heat is not easy to leak out. By cooling the ring forging in a sealed environment, water vapor is not easy to leak out. This makes heating and cooling independent of each other and reduces interference. In addition, when cleaning, the negative pressure on the sealing ring groove 506 can absorb the cleaned rust and dust to avoid secondary pollution. Figure 5-Figure 7 As shown, the limiting assembly 6 includes a limiting platform 601 rotatably mounted on the mounting base 505; a ring of limiting members 602 is disposed on the limiting platform 601. The limiting members 602 include a limiting frame 1 60201 slidably mounted on the limiting platform 601, driven by a driving mechanism 4; one end of the limiting frame 1 60201 is driven by a driving mechanism 5 to rotatably mount a limiting frame 2 60204. During operation, the limiting frames 1 60201 and 2 60204 form an L-shaped structure 1.

[0042] It should be further explained that a motor 4 is provided on the mounting seat 505 to drive the limit platform 601 to rotate, so that the limit platform 601 drives the ring forging to rotate synchronously to ensure uniform heating and cooling effects.

[0043] It should be further explained that the driving structure four includes a motor five, which drives the screw three 60202 to rotate; the screw three 60202 is connected to the limit frame one 60201 through a thread, driving it to slide on the limit platform 601.

[0044] It should be further explained that a radial mounting groove 2 is provided on the limiting platform 601; and the lead screw 3 60202 is rotatably provided on the mounting groove 2.

[0045] It should be further explained that the driving structure five includes a motor six 60203 located at the end of the limiting frame one 60201; the limiting frame two 60204 is driven to rotate by the motor six 60203.

[0046] Through the cooperation of the driving structure four and the driving structure five, the limiting frame 1 60201 moves and the limiting frame 2 60204 rotates, forming multiple groups of L-shaped structures to limit a pair of ring forgings.

[0047] like Figure 8-Figure 9As shown, the cleaning assembly 7 includes a mounting platform 701 located on the rear wall of the access chamber 101; a cleaning disc 703 is rotatably mounted on the mounting platform 701; and a circle of cleaning members 702 are disposed on the cleaning disc 703. The cleaning members 702 include a cleaning frame 1 70201 slidably mounted on the cleaning disc 703, driven by a driving mechanism 6; a cleaning frame 2 70204 is rotatably mounted on one end of the cleaning frame 1 70201, driven by a driving mechanism 7; during operation, the cleaning frames 1 70201 and 70204 form an L-shaped structure 2.

[0048] It should be further explained that a motor 5 is provided on the mounting platform 701 to drive the cleaning disc 703 to rotate, so that the cleaning disc 703 drives the cleaning member 702 to rotate synchronously, and the attachments on the ring forging are evenly removed by mechanical scraping.

[0049] It should be further explained that the driving structure five includes a motor seven, which drives the screw four 70202 to rotate; the screw four 70202 is connected to the cleaning frame one 70201 through a thread, driving it to slide on the cleaning disk 703.

[0050] It should be further explained that radial mounting groove three is provided on the cleaning disc 703; and the lead screw four 70202 is rotatably provided on the mounting groove three.

[0051] It should be further explained that the driving structure 6 includes a motor 70203 located at the end of the cleaning frame 1 70201; the cleaning frame 2 70204 is driven to rotate by the motor 70203.

[0052] Through the cooperation of the driving structure six and the driving structure seven, the cleaning frame one 70201 moves and the cleaning frame two 70204 rotates, forming multiple groups of L-shaped structures with two pairs of ring forgings for cleaning.

[0053] like Figure 7 and Figure 9 As shown, when the limiting platform 601 and the mounting platform 701 are positioned relative to each other, the first pair of L-shaped rings acts on the inner ring wall and bottom of the forging; the second pair of L-shaped rings acts on the outer ring wall and top of the forging; the action modes include limiting and cleaning.

[0054] During feeding, the ring forging rests against the first limiting frame 60201. The second limiting frame 60204 rotates until it contacts the inner wall of the ring forging, forming an L-shaped structure 1 that limits the ring forging's position. When the ring forging flips over so that the limiting platform 601 and the mounting platform 701 are aligned, the cleaning member 702 rotates with the cleaning disk 703. Cleaning frame 1 70201 scrapes and cleans the top of the ring forging, while cleaning frame 2 70204 scrapes and cleans the outer wall of the ring forging. The L-shaped structure 2 then clamps and limits the ring forging from the periphery. The limiting member 602 rotates with the limiting platform 601. Limiting frame 1 60201 scrapes and cleans the bottom of the ring forging, while limiting frame 2 60204 scrapes and cleans the inner wall of the ring forging. After cleaning, the limiting member 602 resumes its positional restraint, allowing the ring forging to proceed to the subsequent heating and cooling processes.

[0055] It should be further explained that the cleaning in the present invention has multiple functions, which can remove the original oxide scale (which is different from the new oxide scale after quenching), remove processing residues (which affect quenching uniformity), and the negative pressure adsorption system (sealing ring groove 506) can also prevent secondary contamination.

[0056] like Figure 10 As shown, the heating structure of the heating assembly 3 includes an insulation tube 301 located in the heating chamber 102 and connected to the isolation port at the lower end; an outer ring heating frame 303 that moves up and down and an inner ring heating head 304 located in the outer ring heating frame 303 are provided in the insulation tube 301; an annular heating space is left between the inner ring heating head 304 and the outer ring heating frame 303 for the ring forging to enter.

[0057] It should be further explained that the insulation tube 301 is an annular cavity structure with a difference between its inner and outer diameters of 1.1-1.3 times the wall thickness of the ring forging to ensure uniform heating. The outer periphery of the insulation tube 301 is filled with insulation liquid, and an electrically controlled slide rail 302 is installed on the inner wall of the insulation tube 301.

[0058] It should be further explained that the outer ring heating frame 303 is ring-shaped and is driven to rise and fall by the electrically controlled slide rail 302. A circle of heating rods is set inside the ring, and a connecting rod 305 is set at the top of the ring; the other end of the connecting rod 305 is connected to the inner ring heating head 304.

[0059] It should be further explained that a second heating rod is provided on the outer periphery of the inner ring heating head 304 .

[0060] When the ring forging enters the heating space, the outer ring heating frame 303 and the inner ring heating head 304 generate heat synchronously through the rotation of the ring forging and the rise and fall of the heating space, so that the ring forging is evenly heated inside and outside. The bottom of the ring forging is overhead, so the bottom can also be heated evenly.

[0061] like Figure 11As shown, the bottom of the piston plate 4 is set on the positioning frame 104; the pressure regulating platform 10 is set below the positioning frame 104; the pressure regulating platform 10 is connected to the exhaust air pump 8 through a pipe; a cooling filter box 9 for the refrigerant to enter and exit is set outside the quenching box 1.

[0062] The pressure regulating platform 10 is driven to inhale and release air by the air pump 8, and the piston plate 4 rises and falls synchronously with the change of the air pressure below, driving the refrigerant from the cooling filter box 9 into the cooling cavity 103. By controlling the liquid level, the ring forging is always immersed in the refrigerant.

[0063] like Figure 12 As shown, the cooling filter box 9 includes a box body 901; a filter screen 902 is provided in the box body 901 and is divided into two spaces, one above and one below, by the filter screen 902; the water inlet end of the liquid inlet pipe 903 is controlled by a liquid inlet valve to control one-way liquid inflow, and the water outlet end extends into the space below the filter screen 902; the water outlet end of the liquid outlet pipe 904 is controlled by a liquid outlet valve to control one-way liquid outflow, and the water inlet end extends into the space above the filter screen 902;

[0064] It should be further explained that both the liquid inlet valve and the liquid outlet valve are pressure one-way valves.

[0065] When piston plate 4 moves downward, liquid inlet pipe 903 introduces the refrigerant, which has passed through filter screen 902, into cooling chamber 103. During the cooling process, the refrigerant absorbs heat and heats up, even generating high-temperature steam. At this point, piston plate 4 moves upward, forcing the steam and high-temperature refrigerant into liquid inlet pipe 903. After filtration, mixing, and cooling, the refrigerant is reintroduced into cooling chamber 103. Repeated cooling ensures a quenching effect.

[0066] Example 2: This example proposes a ring forging quenching method, using the ring forging quenching device described in Example 1, and the steps are as follows:

[0067] S1. The staff puts the ring forging into the box door. The ring forging is placed on the limit frame 1 60201 and rotated to fit the inner wall of the ring forging through the limit frame 2 60204 to form L-shaped structure 1, which limits the ring forging in the air.

[0068] S2. The mounting seat 505 then drives the ring forging to move backward and flip it to face the cleaning assembly 7; the cleaning member 702 rotates with the cleaning disk 703, and the cleaning frame 1 70201 scrapes and cleans the top of the ring forging, and the cleaning frame 2 70204 scrapes and cleans the outer ring wall of the ring forging; the L-shaped structure 2 clamps and limits the ring forging from the outer periphery; the limiting member 602 rotates with the limiting platform 601, and the limiting frame 1 60201 scrapes and cleans the bottom of the ring forging, and the limiting frame 2 60204 scrapes and cleans the inner ring wall of the ring forging; the sealing ring groove 506 absorbs the cleaned rust and dust through negative pressure; the limiting member 602 restores the limiting effect on the ring forging;

[0069] S3, the mounting seat 505 drives the ring forging to flip and move upward to extend into the upper isolation port, and the ring forging enters the heating chamber 102; the mounting seat 505 is in contact with the isolation plate 2 to form a seal, and the ring forging enters the heating space. Through the rotation of the ring forging and the lifting and lowering of the heating space, the outer ring heating frame 303 and the inner ring heating head 304 are heated synchronously, so that the inside and outside of the ring forging are evenly heated;

[0070] S4, heating to the set time and temperature, and then keeping the temperature until austenitization is completed;

[0071] S5. The mounting seat 505 drives the ring forging to flip and move downward until it extends into the lower isolation port, and the ring forging enters the cooling chamber 103. The piston plate 4 moves downward, and the liquid inlet pipe 903 introduces the refrigerant passing through the filter 902 into the cooling chamber 103. The piston plate 4 moves upward, on the one hand, adjusting the liquid level so that the ring forging is always immersed in the refrigerant, and on the other hand, pressurizing the steam and high-temperature refrigerant into the liquid inlet pipe 903. After filtering and mixed cooling, the refrigerant is reintroduced into the cooling chamber 103. Through repeated and multiple cooling, the quenching effect is ensured.
