Description

Technical Field

[0001] The invention belongs to the technical field of nitriding alloy forming, in particular to a processing and forming process for nitriding alloy steel. Background Art

[0002] Nitriding alloy steel is a special steel with high-quality steel as the base material. Through the nitriding process, a high-hardness and high-strength nitride layer is formed on the surface, thereby improving the comprehensive performance of the steel. The nitriding treatment usually involves diffusing nitrogen atoms on the surface of the alloy steel and dissolving them in the iron matrix in a high-temperature ammonia atmosphere to form a nitrogen-rich solid solution layer. This nitride layer can significantly improve the hardness, wear resistance and corrosion resistance of the alloy steel.

[0003] In the prior art, when nitriding alloy steel is cast, high-temperature molten steel is generally received manually through tools, and then the molten steel is poured into the mold through the tools. However, manual pouring is labor-intensive and inefficient. In a high-temperature environment, the working comfort of the workers is poor. When the workers receive and pour the molten steel, the molten steel is easily splashed out and falls on the workers, causing danger.

[0004] Therefore, we propose a processing technology for nitriding alloy steel to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that when nitriding alloy steel is cast and formed, high-temperature molten steel is generally taken in manually through tools, and then the molten steel is poured into the mold through the tools. However, manual pouring has high work intensity and low efficiency. In a high temperature environment, the working comfort of the workers is poor. When the workers take and pour the molten steel, the molten steel is easy to splash out and fall on the workers, causing danger. A processing and forming process for nitriding alloy steel is proposed.

[0006] The purpose of the present invention can be achieved by the following technical solution: comprising the following steps;

[0007] Step 1: Pour the nitriding alloy steel stock solution that has been melted into liquid at high temperature into the insulation tank for temporary storage. Then, move a set of molds to the bottom of the discharge pipe, start the motor, and the motor drives the shaft 1 and the intermittent gear to rotate. The shaft 1 drives the shaft 2 to rotate through the right transmission mechanism, so that the shaft 2 drives the turntable 1 to rotate. The rotation of the turntable 1 will first drive the lifting rod to move upward. Because the insulation tank is installed above the mounting seat through the hinge shaft, when the lifting rod moves upward, it can drive the insulation tank to tilt to the left through the hinge rod. At this time, open the discharge pipe. The electric valve at the bottom of the insulation tank flows out through the discharge pipe and flows into the inside of the mold. While the insulation tank is pouring into the inside of the mold, the argon pipe simultaneously inputs argon into the inside of the mold to promote the floating of inclusions, improve the fluidity of the molten steel, even the temperature of the molten steel, and improve the quality of the casting. As the lifting rod continues to move upward, the greater the tilt angle of the insulation tank to the left, the faster the liquid is discharged through the discharge pipe. Then, when the turntable drives the lifting rod to move to the uppermost end, the liquid injection into the mold is completed. At this time, the electric valve is closed to complete the pouring of the mold.

[0008] Step 2: After the pouring of the mold located below the discharge pipe is completed, when the turntable 1 continues to rotate to drive the lifting rod to move downward, the rotating shaft 1 drives the rotating rod 2 and the turntable 2 to rotate synchronously through the left transmission mechanism, so that the protrusion on the surface of the turntable 2 rotates to contact the upper surface of the left end of the lever, and then under the continuous rotation of the turntable 2, the protrusion presses the left end of the lever downward, so that the right end of the lever is lifted upward, thereby pushing the connecting rod, the lifting block, the argon gas tube and the slider upward, so that the lower end of the argon gas tube is moved out from the upper end of the mold, so as to avoid damage to the argon gas tube when the mold is switched;

[0009] Step 3, after the argon gas tube is removed from the inside of the mold, the gear teeth of the intermittent gear rotate to mesh with the driven gear, driving the driven gear to rotate, and the driven gear drives the rotating rod 1 and sprocket 1 to rotate, so that the sprocket 1 drives the sprocket 2 and the transmission roller to rotate through the tooth chain, so that the transmission roller drives the conveyor belt to rotate, and then the conveyor belt can transport the mold after casting backward, and the empty mold at the front end of its upper surface is moved backward to the bottom of the discharge pipe. At the same time, the pouring port at the upper end of this mold is located directly below the outlet of the discharge pipe, and then the gear teeth of the intermittent gear no longer mesh with the driven gear. The conveyor belt stops rotating, and the convex block on the surface of the second turntable no longer contacts the lever, so that the slider moves downward under the action of the spring, and then drives the lifting block and the argon gas tube to reset downward, so that the lower end of the argon gas tube is inserted into the upper end of the new mold. Then the turntable drives the lifting rod to move to the lowest end, so that the insulation tank returns to its initial state, and the mold casting and replacement work is completed. Then, with the motor working continuously, the turntable drives the insulation tank to tilt to the left again through the lifting rod to perform the casting work, so as to realize the automatic casting and molding of nitrided alloy steel.

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.

The right end of the second rotating shaft 303 is provided with a turntable 1 304, and the lower end of the right surface of the turntable 1 304 is rotatably mounted with a lifting rod 305. The upper end of the lifting rod 305 is hinged with a heat preservation tank 307 through a hinge rod 306. The outer surfaces of the front and rear sides of the heat preservation tank 307 are hinged on the mounting seat 2. A discharge pipe 308 is provided at the lower left end of the heat preservation tank 307, and an electric valve is provided inside the discharge pipe 308;

[0030] It should be noted that the insulation tank 307 is initially placed vertically, and a sealing cover is hinged on the upper end of the insulation tank 307. After the sealing cover is opened, it is convenient to pour the high-temperature molten alloy material from the upper end of the insulation tank 307 into the insulation tank 307. At the same time, the rotating connection between the lower end of the lifting rod 305 and the turntable 304 is located directly below the center of the turntable 304, so that after the turntable 304 drives the lifting rod 305 to rotate, the connection at the lower end of the lifting rod 305 is always moving upward before moving to the uppermost end of the turntable 304, so that the insulation tank 307 can be smoothly tilted to the left, which is convenient for the subsequent alloy casting and molding work.

[0031] The left end of the rotating shaft 1 302 is connected to the plug-in mechanism 7 through the transmission mechanism 4. The plug-in mechanism 7 includes a fixed seat 701. The fixed seat 701 is arranged on the outer surface of the left side of the frame 1. The left wall of the fixed seat 701 is rotatably mounted with a rotating rod 2 702. The left circumferential surface of the rotating rod 2 702 is provided with a rotating disk 2 703. The surface of the right side of the rotating disk 2 703 is provided with a protrusion 704, and the protrusion 704 is provided with a plurality of protrusions. A lever 705 is arranged at the front end of the right side of the rotating disk 2 703. The protrusion 704 moves the rotating disk 2 703 under the rotation of the rotating disk 2 703. 3, at this time, when the protrusion 704 continues to rotate under the drive of the second rotating disk 703, it can abut against the left end of the lever 705 and press the left end of the lever 705 downward, a fixing plate 711 is provided at the lower end of the left wall of the fixing seat 701, and the fixing plate 711 is provided above the second rotating rod 702, and the middle of the left side of the lever 705 is rotatably installed in front of the fixing plate 711 through a fulcrum, and the fixing plate 711 provides an installation position for the fulcrum, so that the lever 705 can rotate smoothly, and the upper surface of the right end of the lever 705 abuts against the connecting rod 706;

[0032] It should be noted that a plurality of protrusions 704 are concentratedly arranged at the edge of the front end at the lower right side of the turntable 2 703, and the rotation directions of the turntable 2 703 and the turntable 1 304 are the same, so that when the turntable 1 304 drives the lifting rod 305 to move upward, the protrusion 704 will move backward under the drive of the turntable 2 703, and then when the turntable 1 304 drives the lifting rod 305 to move downward, the turntable 2 703 drives the protrusion 704 to contact the lever 705, so that the left side of the lever 705 is pressed down and the right side is lifted. The lifting rod 305 is always in a downward moving state, and then after the next group of molds 6 moves to the bottom of the discharge pipe 308, the protrusion 704 does not contact the lever 705 first, so that after the lever 705 returns to its initial state, the lifting rod 305 moves to the lowermost end under the drive of the turntable 1 304, so that the insulation tank 307 is no longer tilted and returns to its initial state.

[0033] The lower end of the rear side of the connecting rod 706 is fixedly connected to a lifting block 707, and an argon pipe 708 is arranged inside the right end of the lifting block 707, and the left end of the argon pipe 708 is connected to the air pump, so that when the air pump is working, the argon gas can be transported to the inside of the mold 6 through the argon pipe 708, wherein, spraying argon gas into the mold 6 can form bubbles in the molten steel, thereby increasing the stirring effect of the molten steel, and these bubbles will drive the inclusions (such as oxides, sulfides, etc.) in the molten steel to float to the surface of the molten steel during the floating process, thereby reducing the content of inclusions in the steel, improving the purity of the molten steel, and also improving The fluidity of the molten steel can be improved, and the flow resistance during the pouring process can be reduced, so that the molten steel can fill the mold 6 more evenly, avoiding defects such as cold shut and air holes. At the same time, it helps to even out the temperature of the molten steel and reduce local overheating or overcooling, thereby improving the quality of the casting. A spring 710 is arranged inside the upper end of the fixed seat 701, and a slider 709 is arranged at the lower end of the spring 710, and the right side of the slider 709 is fixedly connected to the connecting rod 706. The setting of the slider 709 can limit the upper end of the connecting rod 706 and the lifting block 707 without affecting the vertical movement of the connecting rod 706 and the lifting block 707.

[0034] The transmission mechanism 4 includes a belt driving wheel 401, and the belt driving wheel 401 is connected to a belt driven wheel 403 through a transmission belt 402. The right belt driven wheel 403 is arranged on the circumferential surface of the second rotating shaft 303, and the left belt driven wheel 403 is arranged on the circumferential surface of the left end of the second rotating rod 702. When the motor 301 drives the two belt driving wheels 401 to rotate, the two belt driving wheels 401 respectively drive the two belt driven wheels 403 to rotate through the two transmission belts 402, so that the second rotating shaft 303 and the second rotating rod 702 can rotate synchronously, and then when the heat preservation tank 307 is casting the mold 6, the protrusion 704 will not press the lever 705 downward. After the casting is completed, the protrusion 704 will press the lever 705 downward, so that the argon gas tube 708 is moved out from the inside of the mold 6, which is convenient for the replacement of the mold 6 and realizes the automatic casting and molding of nitriding alloy steel.

[0035] The frame 1 is provided with a transfer mechanism 5, which includes an intermittent gear 501, and the intermittent gear 501 is arranged on the circumferential surface of the right side of the rotating shaft 302. The front end of the intermittent gear 501 is meshedly connected with a driven gear 502. A rotating rod 503 is arranged on the left side of the driven gear 502. The left end of the rotating rod 503 is rotatably mounted on the right side wall of the frame 1, which can limit the rotating rod 503 without affecting the rotation of the rotating rod 503. The circumferential surface of the left side of the rotating rod 503 is provided on the left side of the rotating rod 503. A sprocket wheel 1 504 is arranged on the circumferential surface, and the sprocket wheel 1 504 is connected to a sprocket wheel 2 505 through a toothed chain transmission. A driving roller 506 is arranged on the left side of the sprocket wheel 2 505, and a conveyor belt 507 is arranged on the circumferential surface of the driving roller 506. A mold 6 is placed on the upper surface of the conveyor belt 507, and the injection port at the upper end of the mold 6 is located directly below the discharge pipe 308, so that when the electric valve inside the discharge pipe 308 is opened, the molten steel can be smoothly poured into the inside of the mold 6 through the discharge pipe 308;

[0036] It should be noted that when the rotating shaft 302 rotates to make the insulation tank 307 perform the pouring operation, the gear teeth of the intermittent gear 501 will not mesh with the driven gear 502. After the pouring of the insulation tank 307 is completed and the protrusion 704 on the surface of the turntable 2 703 presses down the left end of the lever 705, so that the argon tube 708 moves out of the mold 6 after the pouring is completed, the gear teeth of the intermittent gear 501 will mesh with the driven gear 502, thereby driving the driven gear 502, the rotating rod 1 503 and the sprocket 1 504 to rotate, so that the sprocket 1 504 drives the sprocket 2 505, the transmission roller 506 and the conveyor belt 507 to rotate through the tooth chain, and then the mold 6 after the pouring is completed is transported backward, and the new mold 6 to be poured is moved to the bottom of the outlet of the discharge pipe 308 to wait for the pouring work.

[0037] A support and reinforcement mechanism 8 is arranged on the upper left side of the mounting seat 2, and the support and reinforcement mechanism 8 includes a support plate 801, and the support plate 801 is arranged on the upper surface of the mounting seat 2, and a fixing rod 802 is arranged on the upper surface of the support plate 801, and the circumferential surfaces of the front and rear ends of the fixing rod 802 are sleeved with sleeve blocks 803, and a spring 2 804 is arranged between the two sleeve blocks 803, and the spring 2 804 is sleeved on the circumferential surface in the middle of the fixing rod 802, and the upper ends of the two sleeve blocks 803 are hinged with support rods 805, and the upper ends of the two support rods 805 are hinged with hinge seats 806, and the hinge seats 806 abut against the left end of the lower surface of the insulation tank 307, and the support and reinforcement mechanism 8 can support the left side of the insulation tank 307 without affecting the rotation of the insulation tank 307, thereby improving the stability of the insulation tank 307.

[0038] When the present invention is used:

[0039] Step 1, pour the nitriding alloy steel stock solution that has been melted into liquid at high temperature into the insulation tank 307 for temporary storage, then transfer a set of molds 6 to the bottom of the discharge pipe 308, then start the motor 301, the motor 301 drives the rotating shaft 1 302 and the intermittent gear 501 to rotate, the rotating shaft 1 302 drives the rotating shaft 2 303 to rotate through the right transmission mechanism 4, so that the rotating shaft 2 303 drives the turntable 1 304 to rotate, and the rotation of the turntable 1 304 will first drive the lifting rod 305 to move upward, because the insulation tank 307 is installed above the mounting seat 2 through the hinge shaft rotation, when the lifting rod 305 moves upward, it can drive the insulation tank 307 to tilt to the left through the hinge rod 306, When the electric valve inside the discharge pipe 308 is opened, the liquid inside the insulation tank 307 flows out through the discharge pipe 308 and flows into the inside of the mold 6. While the insulation tank 307 is pouring into the inside of the mold 6, the argon pipe 708 synchronously inputs argon into the inside of the mold 6 to promote the floating of inclusions, improve the fluidity of the molten steel, even the temperature of the molten steel, and improve the quality of the casting. When the lifting rod 305 continues to move upward, the greater the tilt angle of the insulation tank 307 to the left, the faster the discharge speed of the liquid through the discharge pipe 308. Then, when the turntable 304 drives the lifting rod 305 to move to the uppermost end, the liquid injection into the mold 6 is completed. At this time, the electric valve is closed again to complete the pouring work of the mold 6.

[0040] Step 2, after the casting of the mold 6 located below the discharge pipe 308 is completed, when the turntable 1 304 continues to rotate to drive the lifting rod 305 to move downward, the rotating shaft 1 302 drives the rotating rod 2 702 and the turntable 2 703 to rotate synchronously through the left transmission mechanism 4, so that the protrusion 704 on the surface of the turntable 2 703 rotates to contact the upper surface of the left end of the lever 705, and then under the continuous rotation of the turntable 2 703, the protrusion 704 presses the left end of the lever 705 downward, so that the right end of the lever 705 is lifted upward, thereby pushing the connecting rod 706, the lifting block 707, the argon gas tube 708 and the slider 709 upward, so that the lower end of the argon gas tube 708 is moved out from the upper end of the mold 6, to avoid damage to the argon gas tube 708 when the mold 6 is switched;

[0041] Step 3, after the argon gas tube 708 is removed from the inside of the mold 6, the gear teeth of the intermittent gear 501 rotate to mesh with the driven gear 502, driving the driven gear 502 to rotate, and the driven gear 502 drives the rotating rod 1 503 and the sprocket 1 504 to rotate, so that the sprocket 1 504 drives the sprocket 2 505 and the transmission roller 506 to rotate through the tooth chain, so that the transmission roller 506 drives the conveyor belt 507 to rotate, and then the conveyor belt 507 can transport the mold 6 after casting backward, and the empty mold 6 at the front end of its upper surface is moved backward to the bottom of the discharge pipe 308, and at the same time, the pouring port at the upper end of this mold 6 is located directly below the outlet of the discharge pipe 308, and then the gear teeth of the intermittent gear 501 are no longer meshed with the driven gear 502. The conveyor belt 507 stops rotating and the bump 704 on the surface of the turntable 2 703 no longer contacts the lever 705, so that the slider 709 moves downward under the action of the spring 1 710, and then drives the lifting block 707 and the argon gas tube 708 to reset downward, so that the lower end of the argon gas tube 708 is inserted into the upper end of the new mold 6. Then the turntable 1 304 drives the lifting rod 305 to move to the lowermost end, so that the insulation tank 307 returns to its initial state, completing the casting and replacement of the mold 6. Then, with the continuous operation of the motor 301, the turntable 1 304 drives the insulation tank 307 to tilt to the left again through the lifting rod 305 for casting, thereby realizing the automatic casting and molding of nitrided alloy steel.

A process for nitriding alloy steel processing and forming, characterized in that: The steps include: Step 1: Pour the nitriding alloy steel stock solution melted into liquid at high temperature into the interior of the insulation tank (307) for temporary storage, then transfer a set of molds (6) to the bottom of the discharge pipe (308), then start the motor (301), the motor (301) drives the rotating shaft 1 (302) and the intermittent gear (501) to rotate, the rotating shaft 1 (302) drives the rotating shaft 2 (303) to rotate through the right transmission mechanism (4), so that the rotating shaft 2 (303) drives the turntable 1 (304) to rotate, and the rotation of the turntable 1 (304) will first drive the lifting rod (305) to move upward, because the insulation tank (307) is installed on the top of the mounting seat (2) through the hinge shaft rotation, when the lifting rod (305) moves upward, it can drive the insulation tank (307) to the left through the hinge rod (306). The liquid in the heat preservation tank (307) flows out through the discharge pipe (308) and flows into the mold (6). While the heat preservation tank (307) is pouring the mold (6), the argon pipe (708) simultaneously inputs argon into the mold (6), which promotes the floating of inclusions, improves the fluidity of the molten steel, evens out the temperature of the molten steel, and improves the quality of the casting. As the lifting rod (305) continues to move upward, the greater the tilt angle of the heat preservation tank (307) to the left, the faster the liquid is discharged through the discharge pipe (308). Then, when the turntable (304) drives the lifting rod (305) to move to the uppermost end, the liquid injection into the mold (6) is completed. At this time, the electric valve is closed to complete the pouring of the mold (6). Step 2, after the casting of the mold (6) located below the discharge pipe (308) is completed, when the turntable (304) continues to rotate to drive the lifting rod (305) to move downward, the rotating shaft (302) drives the rotating rod (702) and the turntable (703) to rotate synchronously through the left transmission mechanism (4), so that the protrusion (704) on the surface of the turntable (703) rotates to contact the upper surface of the left end of the lever (705), and then under the continuous rotation of the turntable (703), the protrusion (704) presses the left end of the lever (705) downward, so that the right end of the lever (705) is lifted upward, thereby pushing the connecting rod (706), the lifting block (707), the argon gas tube (708) and the slider (709) upward, so that the lower end of the argon gas tube (708) is moved out from the upper end of the mold (6), so as to avoid damage to the argon gas tube (708) when the mold (6) is switched; Step 3, after the argon gas tube (708) is removed from the inside of the mold (6), the gear teeth of the intermittent gear (501) rotate to mesh with the driven gear (502), driving the driven gear (502) to rotate, and the driven gear (502) drives the rotating rod 1 (503) and the sprocket 1 (504) to rotate, so that the sprocket 1 (504) drives the sprocket 2 (505) and the transmission roller (506) to rotate through the tooth chain, so that the transmission roller (506) drives the conveyor belt (507) to rotate, and then the conveyor belt (507) can transport the mold (6) after casting backward, and the empty mold (6) at the front end of its upper surface is moved backward to the bottom of the discharge pipe (308), and at the same time, the pouring port at the upper end of this mold (6) is located directly below the outlet of the discharge pipe (308), and then the gear teeth of the intermittent gear (501) are no longer engaged with the driven gear (50 2) engagement, so that the conveyor belt (507) no longer rotates, and at the same time, the protrusion (704) on the surface of the turntable (703) no longer contacts the lever (705), so that the slider (709) moves downward under the action of the spring (710), and then drives the lifting block (707) and the argon tube (708) to reset downward, so that the lower end of the argon tube (708) is inserted into the upper end of the new mold (6), and then the turntable (304) drives the lifting rod (305) to move to the lowermost end, so that the insulation tank (307) returns to its initial state, completing the casting and replacement of the mold (6), and then, under the continuous operation of the motor (301), the turntable (304) drives the insulation tank (307) to tilt to the left again through the lifting rod (305) to perform the casting work, thereby realizing the automatic casting and molding of nitrided alloy steel; The invention comprises a mounting seat (2), a frame (1) is arranged on the left side wall of the mounting seat (2), a pouring mechanism (3) is arranged above the mounting seat (2), the pouring mechanism (3) comprises a motor (301), and the motor (301) is arranged on the upper surface of the mounting seat (2) through a motor seat, the power output end of the motor (301) is transmission-connected to a rotating shaft 1 (302), the right end of the rotating shaft 1 (302) is transmission-connected to a rotating shaft 2 (303) through a transmission mechanism (4), and the A turntable (304) is provided at the right end of the second rotating shaft (303), a lifting rod (305) is rotatably installed at the lower end of the right surface of the turntable (304), the upper end of the lifting rod (305) is hingedly connected to a heat preservation tank (307) through a hinge rod (306), the outer surfaces of the front and rear sides of the heat preservation tank (307) are hingedly connected to the mounting seat (2), a discharge pipe (308) is provided at the lower left end of the heat preservation tank (307), and an electric valve is provided inside the discharge pipe (308); The left end of the rotating shaft 1 (302) is connected to a plug-in mechanism (7) through a transmission mechanism (4), and the plug-in mechanism (7) comprises a fixed seat (701), and the fixed seat (701) is arranged on the outer surface of the left side of the frame (1).
