Description

Technical Field

[0001] The present invention relates to the technical field of metal material annealing, and specifically to a temperature-controlled annealing device for metal material processing. Background Art

[0002] Annealing is a metal heat treatment process, which means heating the metal slowly to a certain temperature, maintaining for a sufficient time, and then cooling at an appropriate speed. The purpose is to reduce hardness, improve machinability; reduce residual stress, stabilize dimensions, reduce deformation and crack tendency; refine grains, adjust the structure, and eliminate tissue defects. However, the existing induction heating annealing devices for metal materials are relatively complex, use more electrical appliances, have a higher manufacturing cost, and the operation process is complex. A solution to the above technical problems needs to be proposed; For example, in the patent document with the publication number CN213680788U, this device can transform the current output by the power supply in terms of voltage and current through the setting of a transformer, and can adjust the heating temperature generated by the energized coil. By setting a contact temperature sensor, the temperature of the material being heated can be measured more clearly, which is convenient for adjustment; by setting a driving gear and two driven gears, the device is simple and uses fewer electrical appliances, saving energy. By setting a sector gear, the heating and annealing of the material can be easily achieved, and by setting rollers, the movement of the rack is more flexible; However, during the annealing process of long strip-shaped metal materials by the above device, due to the influence of gravity on the metal material, it is prone to bending deformation, which affects the product quality of the metal material; at the same time, the above device only cools brittle metal materials and cannot quickly cool ductile metal materials, reducing the annealing efficiency of metal materials.

[0003] In view of the above technical defects, a solution is now proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a temperature-controlled annealing device for metal material processing, which solves the problem of being difficult to simultaneously apply to the cooling of brittle and ductile metal materials and improving the annealing efficiency of metal materials; it also solves the problem of being difficult to avoid the influence of gravity on long strip-shaped metal materials, which are prone to bending deformation and affect the product quality of the metal material.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A temperature-controlled annealing device for metal material processing, comprising a support frame. A annealing box is fixedly arranged below the support frame. A first sealing plate is movably arranged inside the annealing box. A cylinder is fixedly installed above the first sealing plate. A clamping tooling is installed at the bottom end of the first sealing plate. An energizing coil is arranged on the outer wall of the annealing box below the clamping tooling. An exhaust hole is opened on the side wall above the annealing box. An atomizing mechanism is arranged on one side of the annealing box away from the exhaust hole; The atomizing mechanism includes a water storage tank fixedly connected to the outer wall of the support frame. An air inlet pipe is fixedly inserted into one side of the bottom of the annealing box. A control valve is arranged on the outer wall of the air inlet pipe. An air delivery pipe is fixedly inserted into the side wall of the air inlet pipe. The air delivery pipe is connected to the outer side wall above the water storage tank. An input pipe is fixedly inserted into the water storage tank. A one-way valve is fixedly arranged on the outer wall of the input pipe above the water storage tank. The output end of the input pipe is communicated with a water spraying box. An atomizing nozzle is horizontally and fixedly inserted into the side wall above the middle of the water spraying box. An adjusting component is arranged above the inside of the water spraying box.

[0006] Further, the adjusting component includes a second piston slidably connected to the inside of the water spraying box. A push rod is fixedly connected to the top of the second piston. The top of the push rod extends to the outside of the water spraying box and is fixedly connected with a limiting ring. A thrust spring is sleeved on the outer wall of the push rod between the limiting ring and the water spraying box. A transmission wheel is rotatably arranged on the outer wall of the push rod above the limiting ring. A water spraying hose is fixedly inserted into the second piston.

[0007] Further, the input end of the water spraying hose is located below the second piston, and the output end of the water spraying hose extends to the outer wall of the second piston close to the atomizing nozzle.

[0008] Further, the water spraying box is fixedly connected to the outer wall of the support frame, and the bottom end of the input pipe is located below the input end of the air delivery pipe.

[0009] Further, a lever is fixedly connected to the outer wall of the output end of the cylinder. A turning frame is arranged above the lever. The outer wall of one side of the turning frame away from the lever is matched with the transmission wheel. The outer wall of the turning frame close to the transmission wheel is rotatably connected to the support frame through a pin.

[0010] Further, a working method of a temperature-controlled annealing device for metal material processing includes the following steps: Step 1, first, fixedly clamp a strip-shaped metal material through the clamping tooling. Extend the extending end of the cylinder to a set length, and extend the metal material into the energizing coil in the annealing box. At this time, the first sealing plate is located above the exhaust hole. By opening the control valve and starting an external ventilation device, inject nitrogen into the annealing box through the air inlet pipe by the external ventilation device, and squeeze out the air through the exhaust hole; The oxygen content in the annealing box is detected by an oxygen detector. When the oxygen content is lower than the threshold value, the control valve is closed, and then the energized coil is turned on to perform annealing operation on the metal material. During the annealing process, since the metal material is in a vertical state inside the energized coil, it will not be bent and deformed due to the influence of gravity, avoiding affecting the product quality of the metal material. The annealing box is sealed by the first sealing plate, and the nitrogen inside the annealing box prevents the metal material from being oxidized; Step two, if the metal material is a brittle metal material, after closing the control valve, the external ventilation device is immediately closed. The extension end of the cylinder contracts and resets, making the brittle metal material contact with the external environment, and then it is allowed to cool naturally to room temperature; Step three, if the metal material is a ductile metal material, after closing the control valve, the external ventilation device is still turned on for a period of time and then closed, so that the nitrogen in the intake pipe is introduced into the water storage tank, increasing the air pressure inside it, causing the purified water in the water storage tank to push open the one-way valve and enter the spray water tank. During the process of the extension end of the cylinder contracting and resetting, the turning frame is driven to rotate by the lever, thus cooperating with the transmission wheel to press the push rod downward. At this time, the second piston slides downward, increasing the air pressure in the spray water tank. When the output end of the water spray hose is connected to the input end of the atomizing nozzle, the purified water in the spray water tank will be sprayed out through the atomizing nozzle to form atomized water for rapid water cooling of the ductile metal material.

[0011] Compared with the prior art, the beneficial effects of the present invention are: In the present invention, nitrogen is injected into the annealing box through the intake pipe by the external ventilation device, and the air is squeezed out through the exhaust hole. The oxygen content in the annealing box is detected by an oxygen detector. When the oxygen content is lower than the threshold value, the control valve is closed, and then the energized coil is turned on to perform annealing operation on the metal material. During the annealing process, since the metal material is in a vertical state inside the energized coil, it will not be bent and deformed due to the influence of gravity, avoiding affecting the product quality of the metal material. The annealing box is sealed by the first sealing plate, and the nitrogen inside the annealing box prevents the metal material from being oxidized; In the present invention, if the metal material is a brittle metal material, after closing the control valve, the external ventilation device is immediately closed, and the extending end of the cylinder contracts and resets, so that the brittle metal material contacts the external environment, and then it is allowed to cool naturally to room temperature; if the metal material is a ductile metal material, after closing the control valve, the external ventilation device is still kept open for a period of time and then closed, so that the nitrogen in the intake pipe is introduced into the water storage tank, and the purified water in the water storage tank pushes open the one-way valve and enters the spray water tank. During the process of the extending end of the cylinder contracting and resetting, the second piston slides downward, increasing the air pressure in the spray water tank. When the output end of the spray hose is communicated with the input end of the atomizing nozzle, the purified water in the spray water tank will be sprayed out through the atomizing nozzle to form atomized water for rapid water cooling of the ductile metal material. This device realizes the cooling applicable to both brittle metal materials and ductile metal materials, thereby improving the annealing efficiency of the metal material.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0015] Embodiment

[0016] As Figures 1-5 shown, a temperature-controlled annealing device for metal material processing proposed in this embodiment includes a support frame 7. A annealing box 5 is fixedly arranged below the support frame 7. A first sealing plate 6 is movably arranged inside the annealing box 5. The annealing box 5 is sealed by the first sealing plate 6. The nitrogen gas inside the annealing box 5 prevents the metal material from being oxidized. A cylinder 8 is fixedly installed above the first sealing plate 6. A clamping tooling 9 is installed at the bottom end of the first sealing plate 6. An energizing coil 10 is arranged on the outer wall of the annealing box 5 below the clamping tooling 9. An exhaust hole 13 is opened on the side wall above the annealing box 5. An atomizing mechanism 2 is arranged on one side of the annealing box 5 away from the exhaust hole 13. The long strip-shaped metal material is fixedly clamped by the clamping tooling 9. The extending end of the cylinder 8 extends to a set length, and the metal material is extended into the energizing coil 10 in the annealing box 5. At this time, the first sealing plate 6 is located above the exhaust hole 13. By opening the control valve 11 and starting the external ventilation device, nitrogen gas is injected into the annealing box 5 through the inlet pipe 3 by the external ventilation device, and the air is extruded through the exhaust hole 13. An oxygen detector is used to detect the oxygen content in the annealing box 5. When the oxygen content is lower than the threshold value, the control valve 11 is closed, and then the energizing coil 10 is started to perform annealing operation on the metal material. During the annealing process, since the metal material is in a vertical state in the energizing coil 10, it will not be bent and deformed due to the influence of gravity, avoiding affecting the product quality of the metal material; the clamping principle of the clamping tooling 9 is the same as that of the patent document with the patent number CN212833877U for clamping metals.

[0017] The atomizing mechanism 2 includes a water storage tank 23 fixedly connected to the outer wall of the support frame 7. An inlet pipe 3 is fixedly inserted into one side of the bottom of the annealing box 5. A control valve 11 is arranged on the outer wall of the inlet pipe 3. An air delivery pipe 24 is fixedly inserted into the side wall of the inlet pipe 3. The air delivery pipe 24 is connected to the outer side wall above the water storage tank 23. An input pipe 22 is fixedly inserted into the water storage tank 23. A one-way valve is fixedly arranged on the outer wall of the input pipe 22 above the water storage tank 23. The output end of the input pipe 22 communicates with a water spraying tank 25. An atomizing nozzle 26 is horizontally fixedly inserted into the side wall above the water spraying tank 25. An adjusting component 21 is arranged above the inside of the water spraying tank 25. If the metal material is a brittle metal material, after the control valve 11 is closed, the external ventilation device is immediately closed. The extending end of the cylinder 8 contracts and resets, so that the brittle metal material is in contact with the external environment, and then it is allowed to cool naturally to room temperature.

[0018] As Figures 1-5As shown in the figure, the adjusting component 21 includes a second piston 212 that is slidably connected to the inside of the water spraying tank 25. A push rod 211 is fixedly connected to the top of the second piston 212. The top of the push rod 211 extends to the outside of the water spraying tank 25 and is fixedly connected with a limit ring 215. A thrust spring 216 is sleeved on the outer wall of the push rod 211 between the limit ring 215 and the water spraying tank 25. A transmission wheel 214 is rotatably arranged on the outer wall of the push rod 211 above the limit ring 215. A water spraying hose 213 is fixedly inserted into the inside of the second piston 212. If the metal material is a ductile metal material, after closing the control valve 11, the external ventilation device is still turned on for a period of time and then turned off, so that the nitrogen in the air inlet pipe 3 is introduced into the water storage tank 23, increasing the air pressure inside it, so that the purified water in the water storage tank 23 pushes open the one-way valve and enters the water spraying tank 25. During the process of the extending end of the cylinder 8 contracting and resetting, the turning frame 1 is driven to rotate by the dial rod 12, so as to cooperate with the transmission wheel 214 to press the push rod 211 to move downward. At this time, the second piston 212 slides downward, increasing the air pressure in the water spraying tank 25. When the output end of the water spraying hose 213 is communicated with the input end of the atomizing nozzle 26, the purified water in the water spraying tank 25 will be sprayed out through the atomizing nozzle 26 to form atomized water for rapid water cooling of the ductile metal material. This device can be used for cooling both brittle metal materials and ductile metal materials at the same time, thus improving the annealing efficiency of the metal material.

[0019] As Figures 1-3 shown, the input end of the water spraying hose 213 is located below the second piston 212, and the output end of the water spraying hose 213 extends to the outer wall of the second piston 212 close to the atomizing nozzle 26.

[0020] As Figure 1 、 2 shown, the water spraying tank 25 is fixedly connected to the outer wall of the support frame 7, and the bottom end of the input pipe 22 is located below the input end of the gas transmission pipe 24.

[0021] As Figures 1-5 shown, a dial rod 12 is fixedly connected to the outer wall of the output end of the cylinder 8. A turning frame 1 is arranged above the dial rod 12. The outer wall of the turning frame 1 away from the dial rod 12 cooperates with the transmission wheel 214, and the outer wall of the turning frame 1 close to the transmission wheel 214 is rotatably connected to the support frame 7 through a pin.

[0022] The working process and principle of the present invention are as follows: Step 1: First, fix and clamp the long strip-shaped metal material through the clamping tooling 9. Extend the extending end of the cylinder 8 to a set length, and insert the metal material into the energized coil 10 in the annealing box 5. At this time, the first sealing plate 6 is located above the exhaust hole 13. By opening the control valve 11 and turning on the external ventilation device, inject nitrogen into the annealing box 5 through the inlet pipe 3 by the external ventilation device, and squeeze out the air through the exhaust hole 13. Detect the oxygen content in the annealing box 5 with an oxygen detector. When the oxygen content is lower than the threshold, close the control valve 11, and then turn on the energized coil 10 to perform annealing operation on the metal material. During the annealing process, since the metal material is in a vertical state in the energized coil 10, it will not be bent and deformed due to the influence of gravity, avoiding affecting the product quality of the metal material. Seal the annealing box 5 through the first sealing plate 6, and avoid oxidation of the metal material through the nitrogen inside the annealing box 5; Step 2: If the metal material is a brittle metal material, immediately turn off the external ventilation device after closing the control valve 11. Retract and reset the extending end of the cylinder 8 to make the brittle metal material contact with the external environment, and then let it cool naturally to room temperature; Step 3: If the metal material is a ductile metal material, after closing the control valve 11, still turn on the external ventilation device for a period of time and then turn it off, so that the nitrogen in the inlet pipe 3 is introduced into the water storage tank 23, increasing the air pressure inside it, and making the purified water in the water storage tank 23 push open the one-way valve and enter the spray water tank 25. During the process of retracting and resetting the extending end of the cylinder 8, drive the flipping frame to rotate through the lever 12, so as to cooperate with the transmission wheel 214 to press the push rod 211 to move downward. At this time, the second piston 212 slides downward, increasing the air pressure in the spray water tank 25. When the output end of the spray water hose 213 is connected to the input end of the atomizing nozzle 26, the purified water in the spray water tank 25 will be sprayed out through the atomizing nozzle 26 to form atomized water for rapid water cooling of the ductile metal material. This device realizes cooling suitable for both brittle metal materials and ductile metal materials at the same time, thus improving the annealing efficiency of the metal material.
