[0001] The present invention relates to the technical field of super ferritic stainless steel processing, and particularly relates to a solution heat treatment furnace for super ferritic stainless steel used for a machine tool guide rail. Background Art

[0002] As a nickel-saving and low-cost stainless steel, super ferritic stainless steel has been widely used in many fields. Super ferritic stainless steel (high-chromium and high-molybdenum ferritic stainless steel) is a type of resource-saving and high-performance material, which has excellent corrosion resistance, good thermal conductivity and mechanical properties, and is mainly used as a low-cost heat exchange material in corrosive environments, such as replacing copper tubes and titanium tubes to manufacture condensers for coastal power plants and machine tool guide rails, etc.

[0003] In the prior art, when the solution heat treatment furnace is working, it is necessary to discharge the internal waste heat gas, which leads to waste of the discharged waste heat. At the same time, when the super ferritic stainless steel enters the treatment furnace at room temperature for heating, it is easy to cause the structure of the stainless steel pipe to be unstable, and it also requires longer heating time, reducing the energy-saving effect of the solution heat treatment furnace. Summary of the Invention

[0004] The purpose of the present invention is to solve the following disadvantages in the prior art: when the solution heat treatment furnace is working, it is necessary to discharge the internal waste heat gas, which leads to waste of the discharged waste heat. At the same time, when the super ferritic stainless steel enters the treatment furnace at room temperature for heating, it is easy to cause the structure of the stainless steel pipe to be unstable, and it also requires longer heating time, reducing the energy-saving effect of the solution heat treatment furnace. Therefore, a solution heat treatment furnace for super ferritic stainless steel used for a machine tool guide rail is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme: A solution heat treatment furnace for super ferritic stainless steel used for a machine tool guide rail, including a box body and two cross plates. Both of the two cross plates are fixedly connected inside the box body, and a plurality of rollers are rotatably connected between the two cross plates; the box body is equipped with a preheating component, and the preheating component includes a gas collecting box, an elliptical cylinder, a piston plate, and an exhaust pipe. The gas collecting box is slidably connected to the upper end of the box body. On both sides of one end of the box body, moving plates are respectively slidably connected. The two elliptical cylinders are respectively fixedly connected to the moving plates. One end of the piston plate is slidably connected inside the elliptical cylinder. A connecting pipe is fixedly communicated between the gas collecting box and the elliptical cylinder. The elliptical cylinder is fixedly communicated with an exhaust pipe, and an exhaust port is opened on the lower side wall of the exhaust pipe; a fixing plate is fixedly connected to one of the cross plates, a servo motor is fixedly connected to the fixing plate, and the driving shaft of the servo motor is fixedly connected to one of the rollers.

[0006] Preferably, the preheating component further includes a push plate and a second spring. The two push plates are respectively fixedly connected to one end of the piston plate away from the elliptical cylinder, and the second spring is fixedly connected between the push plate and the moving plate.

[0007] Preferably, one-way valves are installed on both the connecting pipe and the exhaust pipe, and the exhaust pipe is arranged in an L shape.

[0008] Preferably, L-shaped clamping plates are respectively fixedly connected to the two moving plates, a rotating rod is threadedly connected between the two clamping plates, and tooth threads are respectively provided at both ends of the rotating rod.

[0009] Preferably, a rotating shaft is fixedly connected to the roller rotatably connected to the driving shaft of the servo motor. The rotating shaft passes through the cross plate and is fixedly connected with a cam.

[0010] Preferably, a vertical plate is fixedly connected to one side of the box body. An extrusion plate is slidably connected to the vertical plate. The extrusion plate is arranged on one side of the cam. The extrusion plate is arranged in a T shape, and a first spring is fixedly connected between one end of the extrusion plate and the vertical plate.

[0011] Preferably, tooth threads matching the rotating rod are provided on the lower surface of the extrusion plate, and the extrusion plate is meshed with the rotating rod through the tooth threads.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: When the cam rotates continuously, every time the extrusion plate is pushed to move, the two push plates will move to the center once, which has a corrective effect on the super ferritic stainless steel, avoiding the poor processing and heating effect caused by the offset of the super ferritic stainless steel during movement on the roller.

[0016] Driven by the servo motor, one of the rollers rotates. The rotation of the roller can drive the super ferritic stainless steel to move and enter the box body for processing, realizing the effect of automatic feeding during the processing of the super ferritic stainless steel.

[0017] When both push plates are in contact with the side wall of the super ferritic stainless steel, as the clamping plate, the moving plate, and the elliptical cylinder continue to move, the piston plate squeezes the gas in the elliptical cylinder.

Detailed Embodiment

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Refer to Figures 1-7, A solution heat treatment furnace for super ferritic stainless steel used in machine tool guideways, comprising a box body 1 and two cross plates 10. Both of the two cross plates 10 are fixedly connected inside the box body 1. A plurality of rollers 9 are rotatably connected between the two cross plates 10. One side wall of the box body 1 is fixedly connected with a heater 15, and one end of the heater 15 is arranged above the rollers 9.

[0022] The box body 1 is equipped with a preheating component. The preheating component includes a gas collecting box 2, an elliptical cylinder 5, a piston plate 22, and an exhaust pipe 6. The gas collecting box 2 is slidably connected to the upper end of the box body 1. On both sides of one end of the box body 1, moving plates 4 are respectively slidably connected. The two elliptical cylinders 5 are respectively fixedly connected to the moving plates 4. One end of the piston plate 22 is slidably connected inside the elliptical cylinder 5. When the piston plate 22 is stationary and the elliptical cylinder 5 moves, the gas inside the elliptical cylinder 5 can be pressurized. A connecting pipe 3 is fixedly connected between the gas collecting box 2 and the elliptical cylinder 5. The elliptical cylinder 5 is fixedly connected with an exhaust pipe 6. An exhaust port is opened on the lower side wall of the exhaust pipe 6. One-way valves are installed on both the connecting pipe 3 and the exhaust pipe 6. The exhaust pipe 6 is arranged in an L shape, and the gases discharged from the two exhaust pipes 6 can cover the upper surface of the super ferritic stainless steel. A fixing plate 8 is fixedly connected to one of the cross plates 10. A servo motor 7 is fixedly connected to the fixing plate 8. The driving shaft of the servo motor 7 is fixedly connected to one of the rollers 9. When one of the rollers 9 rotates, it can drive the super ferritic stainless steel to move, and the rotation states of the remaining rollers 9 can reduce the friction with the super ferritic stainless steel. The preheating component further includes a push plate 24 and a second spring 23. The two push plates 24 are respectively fixedly connected to one end of the piston plate 22 away from the elliptical cylinder 5. The second spring 23 is fixedly connected between the push plate 24 and the moving plate 4.

[0023] L-shaped clamping plates 20 are respectively fixedly connected to the two moving plates 4. A rotating rod 19 is threadedly connected between the two clamping plates 20. Threads are respectively provided at both ends of the rotating rod 19. A rotating shaft 11 is fixedly connected to the roller 9 rotatably connected to the driving shaft of the servo motor 7. The rotating shaft 11 passes through the cross plate 10 and is fixedly connected with a cam 12. An extrusion plate 13 is arranged on one side of the cam 12. When the cam 12 rotates, it can intermittently push the extrusion plate 13 to move. A vertical plate 14 is fixedly connected to one side of the box body 1. The extrusion plate 13 is slidably connected to the vertical plate 14. The extrusion plate 13 is arranged in a T shape. A first spring 18 is fixedly connected between one end of the extrusion plate 13 and the vertical plate 14. The first spring 18 is used to push the extrusion plate 13 to move back. Threads matching the rotating rod 19 are provided on the lower surface of the extrusion plate 13. The extrusion plate 13 is meshed with the rotating rod 19 through the threads. When the extrusion plate 13 moves, it can drive the rotating rod 19 to rotate.

[0024] The lower end of the air collecting box 2 is fixedly communicated with a placement box 21. A circular hole is formed in the bottom wall of the placement box 21, and a through port is formed in one side wall of the placement box 21. The gas in the box body 1 enters the placement box 21 through the through port to facilitate filtration by activated carbon. A storage tray 16 is slidably connected in the through port. A metal block is fixedly provided on one side of the storage tray 16. The storage tray 16 is filled with activated carbon. A magnetic block 17 is fixedly connected to one side of the placement box 21. The magnetic block 17 is arranged on one side of the metal block. The fixation of the storage tray 16 and the placement box 21 can be completed through the adsorption of the magnetic block 17 and the metal block.

[0025] In the present invention, during use, first place the super ferritic stainless steel on the upper side of the plurality of rollers 9, drive the servo motor 7. Driven by the servo motor 7, one of the rollers 9 rotates. The rotation of the roller 9 can drive the super ferritic stainless steel to move and enter the box body 1 for processing, realizing the effect of automatic feeding during the processing of the super ferritic stainless steel.

[0026] At the same time, when the cam 12 rotates along with the roller 9 connected to the servo motor 7 through the rotating shaft 11, it can push the pressing plate 13 to slide on the vertical plate 14 and compress the first spring 18. As the pressing plate 13 moves, it can drive the meshing-connected rotating rod 19 to rotate. The rotation of the rotating rod 19 can drive the two clamping plates 20 to move centrally. When the elliptical cylinder 5 moves along with the moving plate 4 as the clamping plates 20 move, the push plate 24 first contacts the side wall of the super ferritic stainless steel. Since both push plates 24 contact the side wall of the super ferritic stainless steel, when the clamping plates 20, the moving plate 4, and the elliptical cylinder 5 continue to move, when the push plate 24 is limited by the super ferritic stainless steel and no longer moves, it can compress the second spring 23. When the push plate 24 moves centrally under the thrust of the second spring 23, it can push the super ferritic stainless steel to the middle position of the roller 9, avoiding poor heating effect during processing after the super ferritic stainless steel deviates and enters the box body 1.

[0027] When the cam 12 continues to rotate and no longer pushes the pressing plate 13, the pressing plate 13 moves back under the push of the first spring 18 and drives the rotating rod 19 to rotate back. At this time, the two clamping plates 20 move away from each other, and at the same time, the push plate 24 will also move away from the super ferritic stainless steel along with the moving plate 4. Therefore, when the cam 12 rotates continuously, every time the pressing plate 13 is pushed to move, the two push plates 24 will move centrally once, which has a corrective effect on the super ferritic stainless steel and avoids the super ferritic stainless steel from deviating during movement on the roller 9.

[0028] When both push plates 24 are in contact with the side wall of the super ferritic stainless steel, as the clamping plate 20, the moving plate 4, and the elliptical cylinder 5 continue to move, the piston plate 22 squeezes the gas in the elliptical cylinder 5. At this time, the one-way valve on the connecting pipe 3 closes, and the one-way valve on the exhaust pipe 6 opens. The gas in the elliptical cylinder 5 can enter the exhaust pipe 6 and be discharged to the surface of the super ferritic stainless steel on the rotating roller 9 through the exhaust port, which can preheat the super ferritic stainless steel, avoid and save the heating and processing time in the box body 1. At the same time, when the two clamping plates 20 move away from each other, the push plate 24 can move back under the push of the second spring 23. At this time, the piston plate 22 moves back in the elliptical cylinder 5. At this time, the one-way valve on the connecting pipe 3 opens, and the one-way valve on the exhaust pipe 6 closes. Therefore, the hot gas in the box body 1 can enter the elliptical cylinder 5 through the air collecting box 2 and the connecting pipe 3 and be discharged through the exhaust pipe 6. In this way, as the two moving plates 4 approach and move away from each other, the excess heat in the box body 1 can be continuously transported to the super ferritic stainless steel outside the box body 1 for preheating.

[0029] The gas in the box body 1 will enter the air collecting box 2 through the placement box 21. The gas is filtered by the activated carbon in the storage tray 16. The filtered gas is discharged to the super ferritic stainless steel through the exhaust pipe 6. When the activated carbon needs to be replaced, the air collecting box 2 needs to be pulled out. Since the placement box 21 is fixedly connected to the air collecting box 2, the air collecting box 2 and the placement box 21 are separated from the box body 1. At this time, the storage tray 16 is pulled, and the metal sheet moves away from the magnet 17 as the storage tray 16 moves, so that the activated carbon in the storage tray 16 can be taken out, and new activated carbon can be put in. Then the storage tray 16 is pushed back to move into the placement box 21. At this time, the metal block is adsorbed by the magnet, which can realize the fixing function of the storage tray 16 and the placement box 21, and achieve the effect of quickly replacing the activated carbon.

[0030] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
