Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of high manganese steel wear-resistant parts, specifically a quenching device for the production of high manganese steel wear-resistant parts. Background Technology
[0002] The main characteristic of high manganese steel is its excellent work hardening ability. When subjected to impact or extrusion, the surface metal can harden rapidly to form a high-hardness wear-resistant layer while maintaining good toughness and impact resistance. It usually requires quenching treatment to improve surface hardness and wear resistance.
[0003] The quenching process of high manganese steel mainly adopts electromagnetic induction heating, that is, using an electromagnetic coil to generate an alternating magnetic field, inducing eddy currents inside the high manganese steel bar, thereby rapidly raising the temperature. When the surface temperature of the high manganese steel bar reaches the austenitizing temperature (generally 1000-1100℃), it is then rapidly water-cooled.
[0004] During the quenching process, the high manganese steel bar moves with the change of heating position, but the spray range of the nozzle cannot be adjusted accordingly, which may cause the cooling area to deviate from the high temperature zone, thus affecting the quenching effect. Current solutions are mostly to increase the number of nozzles to expand the cooling range or to increase the water pressure to compensate for the insufficient spray range, but these solutions still cannot effectively solve the problem of cooling accuracy.
[0005] Therefore, there is an urgent need for a quenching device for the production of high manganese steel wear-resistant parts to solve the technical defects mentioned above. Utility Model Content
[0006] The purpose of this invention is to provide a quenching device for the production of high manganese steel wear-resistant parts, so as to solve the problem of uneven cooling caused by the cooling zone deviating from the high temperature zone as mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a quenching device for producing high manganese steel wear-resistant parts, comprising a cooling water tank and a mounting frame. The mounting frame is mounted on the top of the cooling water tank, and a water tank is provided on the left side of the cooling water tank. A first motor is fixedly connected to the left side of one end of the cooling water tank, and a lead screw is fixedly connected to the output shaft of the first motor. The lead screw is movably mounted on the outer wall of the cooling water tank, and a lead screw nut is movably sleeved on the outside of the lead screw. A movable frame is fixedly connected to the outside of the lead screw nut, and a nozzle is fixedly connected to the top of the movable frame. A water pump is installed at the front end of the water tank, and the water pump and the nozzle are connected by a hose.
[0008] As a further technical solution of this utility model, a guide rod fixed to the outer wall of the cooling water pool is provided below the lead screw, and the lead screw nut is sleeved on the outside of the guide rod and moves.
[0009] As a further technical solution of this utility model, a cylinder is fixedly connected to the left side of the inner wall of the mounting frame, and a limiting plate is fixedly connected to the cylinder through a piston rod. A rotating block is movably connected inside the limiting plate, and a rotating seat is movably connected to the right side of the inner wall of the mounting frame. A positioning clamp is fixedly connected to the left side of the rotating seat, and the positioning clamp is flush with the height of the limiting plate.
[0010] As a further technical solution of this utility model, the rotating block rotates within the limiting plate in a vertical direction of 360°, and a third motor is installed on the right side of the rotating base, with the output shaft of the third motor fixedly connected to the positioning fixture.
[0011] As a further technical solution of this utility model, the positioning fixture is equipped with adjustable locking rods at both the top and bottom, and the ends of the locking rods are fixedly connected to clamping blocks, which are two sets of semi-circular metal plates.
[0012] As a further technical solution of this utility model, a second motor is fixedly connected to the top right side of the mounting bracket, a threaded rod is fixedly connected to the output shaft of the second motor, a threaded block is movably sleeved on the outside of the threaded rod, an electromagnetic coil is fixedly connected to the bottom end of the threaded block, and the electromagnetic coil is located outside the high manganese steel rod and moves.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the quenching device for the production of high manganese steel wear-resistant parts not only realizes mobile water cooling, reducing defects such as cracks and stress concentration, and achieves uniform heating to ensure uniform distribution of the quenching layer, but also realizes adjustable fixtures, reducing the time for changing fixtures and improving production efficiency.
[0014] (1) By setting up a water tank, water pump, first motor, lead screw, lead screw nut, moving frame and nozzle, when the high manganese steel bar enters the alternating magnetic field formed by the electromagnetic coil, eddy currents are generated inside the metal due to electromagnetic induction, causing the internal temperature to rise rapidly and achieving rapid heating. When the surface of the high manganese steel bar reaches the austenitizing temperature, when the electromagnetic coil moves to the right, the first motor drives the lead screw to rotate, the lead screw nut drives the moving frame to move to the right above the cooling water pool, the water pump draws water out of the water tank and sprays it upward through the nozzle, following the electromagnetic coil to move to the right, ensuring mobile water cooling. The nozzle accurately sprays water onto the high temperature metal surface, making it cool rapidly, forming a fine and uniform martensitic structure, improving surface hardness and wear resistance, and ensuring that the water cooling always covers the high temperature area, reducing defects such as cracks and stress concentration caused by uneven cooling.
[0015] (2) By setting up a positioning fixture, clamping block, locking rod, rotating seat, third motor, rotating block, limiting plate, and cylinder, the right side of the high manganese steel bar is located between two sets of clamping blocks. It is clamped by the clamping block, and the piston rod of the cylinder pushes the limiting plate to the right against the high manganese steel bar. When the electromagnetic coil moves outside the high manganese steel bar, the third motor drives the positioning fixture through the rotating seat to drive the high manganese steel bar to rotate at high speed. The left side of the high manganese steel bar is embedded in the rotating block and rotates. The high manganese steel bar is heated evenly around its own axis, thereby ensuring that the quenched layer is evenly distributed and avoiding uneven structure caused by insufficient local cooling.
[0016] (3) By setting a locking rod and a clamping block, the clamping specifications can be adjusted by the locking rod, thereby clamping the high manganese steel bar within a certain range, so that the high manganese steel bar will not loosen or shift when rotating. When the electromagnetic coil moves to the right, the distance between it and the high manganese steel bar remains consistent, reducing the time for changing the clamp and improving production efficiency.

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 protection scope of the present utility model.
[0023] Please see Figure 1-4This utility model provides an embodiment of a quenching device for producing high manganese steel wear-resistant parts, comprising a cooling water tank 21 and a mounting frame 1. The mounting frame 1 is mounted on the top of the cooling water tank 21. A water tank 9 is located on the left side of the cooling water tank 21. A first motor 11 is fixedly connected to the left side of one end of the cooling water tank 21. A lead screw 12 is fixedly connected to the output shaft of the first motor 11. The lead screw 12 is movably mounted on the outer wall of the cooling water tank 21. A lead screw nut 13 is movably sleeved on the outside of the lead screw 12. A movable frame 14 is fixedly connected to the outside of the lead screw nut 13. A [missing information - likely a component or component] is fixedly connected to the top of the movable frame 14. The nozzle 15 and the water tank 9 are equipped with a water pump 10. The water pump 10 and the nozzle 15 are connected by a hose. A guide rod is fixed to the outer wall of the cooling water pool 21 below the lead screw 12. The lead screw nut 13 is sleeved on the outside of the guide rod and moves. The first motor 11, the second motor 2, the third motor 20 and the water pump 10 are all controlled by the controller on the right side of the mounting bracket 1. The electrical connection between the first motor 11, the second motor 2, the third motor 20 and the water pump 10 and the controller is a conventional technical means in this field. This part of the control relationship is not an improvement of this invention, so it will not be described in detail here.
[0024] Specifically, such as Figure 1 and Figure 3 As shown, when the high-manganese steel bar enters the alternating magnetic field formed by the electromagnetic coil 5, eddy currents are generated inside the metal due to electromagnetic induction, causing its internal temperature to rise rapidly and achieving rapid heating. When the surface of the high-manganese steel bar reaches the austenitizing temperature, when the electromagnetic coil 5 moves to the right, the first motor 11 drives the lead screw 12 to rotate, and the lead screw nut 13 drives the moving frame 14 to move to the right above the cooling water pool 21. The water pump 10 draws water out of the water tank 9 and sprays it upward through the nozzle 15, following the movement of the electromagnetic coil 5 to the right, ensuring mobile water cooling. The nozzle 15 accurately sprays the water onto the high-temperature metal surface, making it cool rapidly.
[0025] A cylinder 8 is fixedly connected to the left side of the inner wall of the mounting frame 1. The cylinder 8 is fixedly connected to the limit plate 7 through the piston rod. A rotating block 6 is movably connected inside the limit plate 7. A rotating seat 19 is movably connected to the right side of the inner wall of the mounting frame 1. A positioning clamp 16 is fixedly connected to the left side of the rotating seat 19. The positioning clamp 16 is flush with the height of the limit plate 7. The rotating block 6 rotates 360° vertically inside the limit plate 7. A third motor 20 is installed on the right side of the rotating seat 19. The output shaft of the third motor 20 is fixedly connected to the positioning clamp 16.
[0026] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, the right side of the high manganese steel rod is located between two sets of clamping blocks 17. It is clamped by the clamping blocks 17. The piston rod of the cylinder 8 pushes the limiting plate 7 to the right against the high manganese steel rod. When the electromagnetic coil 5 moves outside the high manganese steel rod, the third motor 20 drives the positioning clamp 16 through the rotating base 19 to drive the high manganese steel rod to rotate at high speed. The left side of the high manganese steel rod is embedded in the rotating block 6 and rotates. The high manganese steel rod is heated evenly around its own axis.
[0027] The positioning fixture 16 has adjustable locking rods 18 installed at both the top and bottom. The locking rods 18 are fixedly connected to clamping blocks 17, which are two sets of semi-circular metal plates. The mounting frame 1 has a second motor 2 fixedly connected to the top right side. The output shaft of the second motor 2 is fixedly connected to a threaded rod 3. A threaded block 4 is movably sleeved on the outside of the threaded rod 3. An electromagnetic coil 5 is fixedly connected to the bottom of the threaded block 4. The electromagnetic coil 5 is located outside the high manganese steel rod and moves.
[0028] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the two sets of clamping blocks 17 can be adjusted in clamping specifications via locking rod 18, thereby clamping the high manganese steel bar within a certain range, ensuring that the high manganese steel bar will not loosen or shift during rotation. When the electromagnetic coil 5 moves to the right, the distance between it and the high manganese steel bar remains consistent.
[0029] Working principle: The right side of the high manganese steel bar is located between two sets of clamping blocks 17. It is clamped by the clamping blocks 17. The piston rod of the cylinder 8 pushes the limiting plate 7 to the right to press against the high manganese steel bar. The second motor 2 drives the threaded rod 3 to rotate. The threaded block 4 on its outside drives the electromagnetic coil 5 to move horizontally. When the high manganese steel bar enters the alternating magnetic field formed by the electromagnetic coil 5, eddy currents are generated inside the metal due to electromagnetic induction, which causes the internal temperature to rise rapidly, achieving rapid heating. When the surface of the high manganese steel bar reaches the austenitizing temperature, when the electromagnetic coil 5 moves to the right, the first motor 11 drives the lead screw 12 to rotate. The lead screw nut 13 drives the moving frame 14 to move to the right above the cooling water pool 21. The water pump 10 draws water out of the water tank 9 and sprays it upward through the nozzle 15. Following the movement of the electromagnetic coil 5 to the right, it ensures mobile water cooling. The nozzle 15 accurately sprays the water flow onto the high-temperature metal surface, making it cool rapidly.
