Description

Technical Field

[0001] This invention relates to the field of alloy heat treatment equipment technology, specifically an intelligent temperature-controlled steel carburizing heat treatment device. Background Technology

[0002] Carburizing heat treatment is a key process for improving the wear resistance, fatigue strength, and service life of mechanical parts. Its core lies in placing steel in a carbon-rich medium, heating and holding it at an austenitizing temperature, allowing carbon atoms to penetrate into the workpiece surface, thereby obtaining an excellent combination of high surface hardness and high core toughness after subsequent quenching.

[0003] Currently, gas carburizing equipment widely used in industry mostly employs pit furnaces or box furnace structures. Traditional equipment typically relies on a single thermocouple for temperature measurement, combined with a simple controller for adjustment. Due to the large furnace volume, high thermal inertia, and fixed arrangement of heating elements, a significant temperature gradient exists within the furnace. This non-uniformity of the temperature field directly results in inconsistent carburizing depth and dispersed microstructure properties in workpieces from the same batch, severely affecting the stability of product quality. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent temperature-controlled steel carburizing heat treatment device to solve the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent temperature-controlled steel carburizing heat treatment device includes a furnace body, a furnace door, a control panel, a side air mechanism, and a support mechanism. The furnace door is hinged to the furnace body. The control panel, the side air mechanism, and the support mechanism are all fixedly connected to the furnace body. There are two sets of side air mechanisms, which are located on both sides of the inner wall of the furnace body. The control panel is connected to the side air mechanism and the support mechanism via electrical signals.

[0006] The side air mechanism includes a cabinet, a fan mechanism, and a corner mechanism. The cabinet is equipped with a valve port located on the side wall of the cabinet. The corner mechanism includes an assembly frame, and the fan mechanism is fixedly connected to the assembly frame.

[0007] This invention relates to a carburizing furnace for heat treatment of steel. The steel is placed on a support structure within the furnace body, and carbon is infiltrated into the steel surface to form a high-carbon hardened layer while maintaining the core's toughness and strength. The furnace body is equipped with zoned resistance heating elements, controlled by an intelligent controller to achieve a precise and uniform temperature field within the furnace chamber. A side-wind mechanism supplies gas to the furnace, creating stable convection and ensuring uniform temperature and protective atmosphere within the furnace. The wind direction and volume are intelligently adjusted according to the load and workpiece shape to eliminate dead zones and low-speed areas, ensuring highly uniform temperature and carbon potential within the furnace and preventing performance differences in workpieces from the same batch. The support structure adjusts the temperature according to the workpiece size; for larger workpieces, the support structure temperature is increased to prevent overcooling at the bottom.

[0008] Furthermore, the side wind mechanism also includes a grille and a rotation mechanism. The grille is fixedly connected to the cabinet, and the cabinet is also provided with a perforated plate. The rotation mechanism includes a turntable, and the torsion mechanism includes a ring wall. The turntable is fixedly connected to the ring wall, and the ring wall is rotatably connected to the perforated plate.

[0009] The gas is connected to an external gas pipe through a valve port and supplied to the furnace body through a grille. The side air mechanisms on both sides form a stable convection. According to the furnace load and the shape of the workpiece, the rotary mechanism and the torsion mechanism drive the fan mechanism to freely adjust the tilt angle, intelligently adjust the air direction, eliminate dead air zones and low speed zones, and ensure a high degree of uniformity of temperature and carbon potential inside the furnace.

[0010] Furthermore, the fan mechanism includes a frame, a rotating shaft, fan blades, and a servo motor. The frame is fixedly connected to the mounting frame and the servo motor. The frame is provided with rotating holes, and there are several sets of rotating holes, rotating shafts, and fan blades. The several sets of rotating holes, rotating shafts, and fan blades are linearly and evenly distributed along the frame. The output end of the servo motor is fixedly connected to the rotating shaft, the rotating shaft is fixedly connected to the fan blades, and the rotating shaft is rotatably connected to the rotating holes. Adjacent rotating shafts are connected via belt drive, and the servo motor is connected to the control panel via electrical signals.

[0011] Based on the furnace loading and workpiece shape, the control panel sends electrical control signals to the servo motor. The servo motor outputs fixed-axis torque to the rotating shaft. The rotating shaft rotates around its axis in the rotating hole. Adjacent rotating shafts are driven by belt transmission, which drives several sets of fan blades evenly distributed linearly along the frame to adjust the tilt angle, intelligently adjust the airflow direction, and eliminate airflow dead zones and low-speed zones.

[0012] Furthermore, the rotary mechanism also includes a torsion motor and a gear rod. The torsion motor is fixedly connected to the cabinet, and the output end of the torsion motor is fixedly connected to the gear rod. The turntable is provided with a side tooth groove, and the gear rod meshes with the tooth surface of the side tooth groove. The torsion motor is connected to the control panel via an electrical signal.

[0013] The control panel sends an electrical control signal to the torsion motor, which outputs a fixed-axis torque to the gear rod. The gear rod rotates around its axis, and the torque is transmitted to the turntable through the meshing of the gear rod with the side tooth groove. The turntable rotates around its axis, changing the overall tilt angle of the fan mechanism in the plane horizontal to the turntable, intelligently adjusting the airflow direction, and eliminating dead airflow angles and low-speed zones.

[0014] Furthermore, the torsion mechanism includes a top plate, a servo cylinder, and a second ball joint rod. The top plate is provided with a second ball joint groove, and the turntable is also provided with a slide rail. There are two sets of servo cylinder, second ball joint groove, second ball joint rod, and slide rail. The two sets of slide rails are perpendicular to each other. The servo cylinder is slidably connected to the slide rail. The output end of the servo cylinder is fixedly connected to the second ball joint rod. The servo cylinder is connected to the control panel via an electrical signal.

[0015] The control panel sends electrical control signals to two sets of servo cylinders. The output end of the servo cylinders changes the displacement distance of the second ball joint according to the electrical control signals. By changing the distance between the output end of the two sets of servo cylinders and the second ball joint, the two sets of servo cylinders are displaced along two sets of mutually perpendicular slide rails, so that the top plate can freely deflect and tilt in the three-axis space, intelligently adjust the airflow direction, and eliminate airflow dead angles and low-speed zones.

[0016] Furthermore, the torsion mechanism also includes a first ball joint rod, and a first ball joint groove is provided on the turntable. The first ball joint rod contacts the first ball joint groove and is fixedly connected to the top plate. The second ball joint rod contacts the second ball joint groove. An inner ring arc surface is provided on the ring wall, and the top plate contacts the inner ring arc surface.

[0017] The output end of the servo cylinder changes the displacement distance of the second ball joint according to the electronic control signal, so that the two sets of servo cylinders move along two sets of mutually perpendicular slide rails respectively. The second ball joint deflects in the second ball joint groove, and the first ball joint deflects in the first ball joint groove, so that the top plate can freely deflect and tilt in the three-axis space.

[0018] Furthermore, the support mechanism includes a base platform, a sliding motor, and baffles. The base platform is fixedly connected to the furnace body, and the sliding motor is fixedly connected to the base platform. There are two sets of sliding motors and baffles, and the two sets of sliding motors and baffles are located on both sides of the base platform. The output end of the sliding motor is fixedly connected to the baffle. The base platform is equipped with side rails, and the baffles are slidably connected to the side rails. The sliding motor is connected to the control panel via electrical signals.

[0019] The workpiece is placed on the bottom platform. The appropriate temperature is adjusted according to the size of the workpiece. When the workpiece is large, the control panel sends an electrical control signal to the sliding motor. The output of the sliding motor drives the baffle to slide along the side rail, so that the high-temperature gas in the furnace body stays in the bottom platform for a long time, increasing the temperature of the bottom platform and ensuring that the bottom of the workpiece will not be too cold, which would cause uneven carburization of the workpiece.

[0020] Furthermore, the base platform is also provided with a direct current channel and a wave channel, and the baffle is provided with air holes. There are several groups of direct current channels, wave channels and air holes. The several groups of direct current channels and wave channels are all linearly and evenly distributed along the base platform. The direct current channels and wave channels are arranged at intervals. The several groups of air holes are linearly and evenly distributed along the baffle. The air holes are in contact with the direct current channels and wave channels.

[0021] When the workpiece is large, the control panel sends an electrical control signal to the sliding motor. The output of the sliding motor drives the baffle to slide along the side rail, so that the air holes correspond one-to-one with the wave channels that are linearly and evenly distributed along the bottom platform. The high-temperature gas circulating in the furnace flows along the wave channels. Because the wave channels have a long path, the high-temperature gas stays in the bottom platform for a long time, increasing the temperature of the bottom platform and ensuring that the bottom of the workpiece will not be undercooled, which would cause uneven carburization of the workpiece.

[0022] Compared with the prior art, the beneficial effects of this invention are as follows: This invention designs a side-wind mechanism, which provides gas to the furnace interior. The side-wind mechanisms on both sides form stable convection, ensuring uniform temperature and protective atmosphere within the furnace. Based on the loading quantity and workpiece shape, the control panel sends electrical control signals to the servo motor. The servo motor drives several sets of fan blades linearly and evenly distributed along the frame to adjust their tilt angle. The control panel also sends electrical control signals to the torsion motor, which drives the turntable to rotate around its axis, changing the overall tilt angle of the fan mechanism in the plane horizontal to the turntable. Furthermore, the control panel sends electrical control signals to two sets of servo cylinders. The output of the servo cylinders changes the displacement distance of the second ball joint according to the electrical control signals, causing the two sets of servo cylinders to move along two sets of mutually perpendicular slide rails. This allows the top plate to freely tilt and deflect within the three-axis space, intelligently adjusting the airflow direction and volume, eliminating dead zones and low-speed areas, ensuring high uniformity of temperature and carbon potential within the furnace, and avoiding uniformity in the same direction. Performance differences exist among workpieces in the furnace. This invention designs a support mechanism that adjusts the temperature according to the workpiece size. When the workpiece is large, the control panel sends an electrical control signal to the sliding motor. The output of the sliding motor drives the baffle to slide along the side rail, so that the air holes correspond one-to-one with the linearly distributed wave channels along the bottom platform. The high-temperature gas circulating in the furnace flows along the wave channels. Because the wave channels have a long path, the high-temperature gas stays in the bottom platform for a long time, increasing the bottom platform temperature and ensuring that the bottom of the workpiece does not become too cold. This invention forms a high-carbon hardened layer by infiltrating carbon elements into the steel surface, while maintaining the toughness and strength of the core. The zoned resistance heating elements are controlled by an intelligent controller to achieve a precise and uniform temperature field in the furnace, making the temperature and protective atmosphere in the furnace uniform. The air direction and volume are intelligently adjusted to eliminate airflow dead zones and low-speed zones, ensuring a high degree of uniformity in furnace temperature and carbon potential. The temperature is adjusted according to the workpiece size. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 1 , Figure 2 , Figure 3As shown, the present invention provides a technical solution for an intelligent temperature-controlled steel carburizing heat treatment device, which includes a furnace body 1, a furnace door 2, a control panel 3, a side air mechanism 4, and a support mechanism 5. The furnace door 2 is hinged to the furnace body 1. The control panel 3, the side air mechanism 4, and the support mechanism 5 are all fixedly connected to the furnace body 1. There are two sets of side air mechanisms 4, which are located on both sides of the inner wall of the furnace body 1. The control panel 3 is connected to the side air mechanism 4 and the support mechanism 5 via electrical signals.

[0035] The side air mechanism 4 includes a cabinet 41, a fan mechanism 43 and a torsion mechanism 45. The cabinet 41 is provided with a valve port 411, which is located on the side wall of the cabinet 41. The torsion mechanism 45 includes an assembly frame 456, and the fan mechanism 43 is fixedly connected to the assembly frame 456.

[0036] This invention relates to a carburizing furnace for heat treatment of steel. The steel is placed on a support mechanism 5 inside the furnace body 1. Carbon is infiltrated into the surface of the steel to form a high-carbon hardened layer while maintaining the toughness and strength of the core. The furnace body 1 is equipped with zoned resistance heating elements, controlled by an intelligent controller to achieve a precise and uniform temperature field within the furnace chamber. A side-wind mechanism 4 supplies gas to the furnace body 1, creating stable convection and ensuring uniform temperature and protective atmosphere within the furnace body 1. The airflow direction and volume are intelligently adjusted according to the load and workpiece shape to eliminate dead zones and low-speed areas, ensuring highly uniform temperature and carbon potential within the furnace and preventing performance differences in workpieces from the same batch. The support mechanism 5 adjusts its temperature according to the workpiece size; for larger workpieces, the temperature of the support mechanism 5 is increased to prevent overcooling at the bottom of the workpiece.

[0037] like Figure 2 , Figure 3 As shown, the side wind mechanism 4 also includes a grille 42 and a rotating mechanism 44. The grille 42 is fixedly connected to the cabinet 41. The cabinet 41 is also provided with a perforated plate 412. The rotating mechanism 44 includes a turntable 443. The torsion mechanism 45 includes a ring wall 451. The turntable 443 is fixedly connected to the ring wall 451. The ring wall 451 is rotatably connected to the perforated plate 412.

[0038] The external gas pipe is connected through valve port 411, and gas is supplied to the inside of furnace body 1 through grille 42. The side wind mechanism 4 on both sides forms a stable convection. According to the furnace load and workpiece shape, the rotary mechanism 44, together with the torsion mechanism 45, drives the fan mechanism 43 to freely adjust the tilt angle, intelligently adjust the air direction, eliminate airflow dead angles and low speed zones, and ensure high uniformity of furnace temperature and carbon potential.

[0039] like Figure 3 , Figure 4As shown, the fan mechanism 43 includes a frame 431, a rotating shaft 432, fan blades 433, and a servo motor 434. The frame 431 is fixedly connected to the mounting frame 456 and the servo motor 434. The frame 431 is provided with a rotating hole 4311. The rotating hole 4311, the rotating shaft 432, and the fan blades 433 are all provided with several sets. The several sets of rotating holes 4311, rotating shafts 432, and fan blades 433 are all linearly and evenly distributed along the frame 431. The output end of the servo motor 434 is fixedly connected to the rotating shaft 432. The rotating shaft 432 is fixedly connected to the fan blades 433. The rotating shaft 432 is rotatably connected to the rotating hole 4311. Adjacent rotating shafts 432 are connected by belt drive. The servo motor 434 is connected to the control panel 3 by electrical signal.

[0040] Based on the furnace loading and workpiece shape, the control panel 3 sends an electrical control signal to the servo motor 434. The servo motor 434 outputs a fixed-axis torque to the rotating shaft 432. The rotating shaft 432 rotates around its axis within the rotating hole 4311. Adjacent rotating shafts 432 are driven by belt transmission, which drives several sets of fan blades 433 linearly and evenly distributed along the frame 431 to adjust their tilt angle, intelligently adjust the airflow direction, and eliminate airflow dead zones and low-speed zones.

[0041] like Figure 5 , Figure 6 As shown, the rotary mechanism 44 also includes a torsion motor 441 and a gear rod 442. The torsion motor 441 is fixedly connected to the cabinet 41, and the output end of the torsion motor 441 is fixedly connected to the gear rod 442. The turntable 443 is provided with a side tooth groove 4431, and the gear rod 442 meshes with the tooth surface of the side tooth groove 4431. The torsion motor 441 is connected to the control panel 3 via an electrical signal.

[0042] Control panel 3 sends an electrical control signal to torsion motor 441. Torsion motor 441 outputs fixed-axis torque to gear rod 442. Gear rod 442 rotates around its axis. Through the meshing of the gear teeth between gear rod 442 and side tooth groove 4431, the torque of gear rod 442 is transmitted to turntable 443. Turntable 443 rotates around its axis, changing the overall tilt angle of fan mechanism 43 in the plane horizontal to turntable 443, intelligently adjusting the airflow direction, and eliminating airflow dead zones and low-speed zones.

[0043] like Figure 7 , Figure 8 As shown, the torsion mechanism 45 includes a top plate 452, a servo cylinder 454, and a second ball joint rod 455. The top plate 452 is provided with a second ball joint groove 4521, and the turntable 443 is also provided with a slide rail 4433. The servo cylinder 454, the second ball joint groove 4521, the second ball joint rod 455, and the slide rail 4433 are all provided in two sets. The two sets of slide rails 4433 are perpendicular to each other. The servo cylinder 454 is slidably connected to the slide rail 4433. The output end of the servo cylinder 454 is fixedly connected to the second ball joint rod 455. The servo cylinder 454 is connected to the control panel 3 via an electrical signal.

[0044] Control panel 3 sends electrical control signals to two sets of servo cylinders 454. The output of servo cylinders 454 changes the displacement distance of the second ball joint rod 455 according to the electrical control signals. By changing the distance between the output of the two sets of servo cylinders 454 and the second ball joint rod 455, the two sets of servo cylinders 454 are displaced along two sets of mutually perpendicular slide rails 4433, so that the top plate 452 can freely deflect and tilt in the three-axis space, intelligently adjust the airflow direction, and eliminate airflow dead angles and low-speed zones.

[0045] like Figure 7 , Figure 8 As shown, the torsion mechanism 45 also includes a first ball joint rod 453, and a first ball joint groove 4432 is provided on the turntable 443. The first ball joint rod 453 contacts the first ball joint groove 4432, and the first ball joint rod 453 is fixedly connected to the top plate 452. The second ball joint rod 455 contacts the second ball joint groove 4521. An inner ring arc surface 4511 is provided on the ring wall 451, and the top plate 452 contacts the inner ring arc surface 4511.

[0046] The output of the servo cylinder 454 changes the displacement distance of the second ball joint rod 455 according to the electronic control signal, so that the two sets of servo cylinders 454 are displaced along the two sets of mutually perpendicular slide rails 4433 respectively. The second ball joint rod 455 deflects in the second ball joint groove 4521, and the first ball joint rod 453 deflects in the first ball joint groove 4432, so that the top plate 452 can freely deflect and tilt in the three-axis space.

[0047] like Figure 7 , Figure 8 As shown, the support mechanism 5 includes a base 51, a sliding motor 52, and a baffle 53. The base 51 is fixedly connected to the furnace body 1, and the sliding motor 52 is fixedly connected to the base 51. There are two sets of sliding motors 52 and baffles 53. The two sets of sliding motors 52 and baffles 53 are located on both sides of the base 51. The output end of the sliding motor 52 is fixedly connected to the baffle 53. A side rail 511 is provided on the base 51. The baffle 53 is slidably connected to the side rail 511. The sliding motor 52 is connected to the control panel 3 via an electrical signal.

[0048] The workpiece is placed on the base platform 51. The appropriate temperature is adjusted according to the size of the workpiece. When the workpiece is large, the control panel 3 sends an electrical control signal to the sliding motor 52. The output end of the sliding motor 52 drives the baffle 53 to slide along the side rail 511, so that the high temperature gas in the furnace body 1 stays in the base platform 51 for a long time, increasing the temperature of the base platform 51 and ensuring that the bottom of the workpiece will not be too cold, which would cause uneven carburization of the workpiece.

[0049] like Figure 9As shown, the base platform 51 is also provided with a direct flow channel 512 and a wave flow channel 513. The baffle 53 is provided with air holes 531. The direct flow channel 512, the wave flow channel 513 and the air holes 531 are provided in several groups. The several groups of direct flow channels 512 and wave flow channels 513 are linearly and evenly distributed along the base platform 51. The direct flow channel 512 and the wave flow channel 513 are arranged at intervals. The several groups of air holes 531 are linearly and evenly distributed along the baffle 53. The air holes 531 are in contact with the direct flow channel 512 and the wave flow channel 513.

[0050] When the workpiece is large, the control panel 3 sends an electrical control signal to the sliding motor 52. The output end of the sliding motor 52 drives the baffle 53 to slide along the side rail 511, so that the air hole 531 corresponds one-to-one with the wave channel 513 that is linearly and evenly distributed along the bottom platform 51. The high-temperature gas circulating in the furnace body 1 flows along the wave channel 513. Because the wave channel 513 has a long path, the high-temperature gas stays in the bottom platform 51 for a long time, increasing the temperature of the bottom platform 51 and ensuring that the bottom of the workpiece will not be undercooled, resulting in uneven carburization of the workpiece.

[0051] The working principle of this invention is as follows: Steel is placed on the support mechanism 5 inside the furnace body 1. Carbon elements are infiltrated into the surface of the steel to form a high-carbon hardened layer, while maintaining the toughness and strength of the core. The furnace body 1 is equipped with zoned resistance heating elements, controlled by an intelligent controller to achieve a precise and uniform temperature field within the furnace chamber. Gas is supplied to the interior of the furnace body 1 through the side air mechanism 4, creating stable convection on both sides, ensuring uniform temperature and protective atmosphere within the furnace body 1. Based on the loading quantity and workpiece shape, the control panel 3 sends electrical control signals to the servo motor 434. The servo motor 434 drives several sets of fan blades 433 linearly and evenly distributed along the frame 431 to adjust their tilt angle. The control panel 3 sends electrical control signals to the torsion motor 441, which drives the turntable 443 to rotate around its axis, changing the overall tilt angle of the fan mechanism 43 in the plane horizontal to the turntable 443. The control panel 3 then sends electrical control signals to two sets of servo motors... The output of the servo cylinder 454 changes the displacement distance of the second ball joint 455 according to the electronic control signal, so that the two sets of servo cylinders 454 move along the two sets of mutually perpendicular slide rails 4433 respectively, so that the top plate 452 can freely deflect and tilt in the three-axis space, intelligently adjust the air direction and air volume, eliminate airflow dead angles and low speed zones, ensure the high uniformity of temperature and carbon potential in the furnace, and avoid performance differences of workpieces in the same furnace. The support mechanism 5 adjusts the temperature according to the size of the workpiece. When the workpiece is large, the control panel 3 sends an electronic control signal to the sliding motor 52. The output of the sliding motor 52 drives the baffle 53 to slide along the side rail 511, so that the air hole 531 corresponds one-to-one with the wave channel 513 linearly and evenly distributed along the bottom platform 51. The high temperature gas circulating in the furnace body 1 flows along the wave channel 513. Because the path of the wave channel 513 is long, the high temperature gas stays in the bottom platform 51 for a long time, increasing the temperature of the bottom platform 51 and ensuring that the bottom of the workpiece does not become too cold.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
