Description

Technical Field

[0001] This invention relates to the field of heat treatment technology for metal sheets, and more particularly to a heat treatment production and processing equipment for metal sheets. Background Technology

[0002] Based on existing technology, it has been found that when existing equipment quenches metal sheets, in order to improve work efficiency, multiple metal sheets are usually sent into the heating furnace at the same time for heating. However, this operation method is prone to causing multiple metal sheets to stack, resulting in some areas overlapping. This leads to uneven and insufficient heating of the overlapping metal sheets.

[0003] Furthermore, after the metal sheet is removed from the heating furnace, it needs to be lifted by an external hoisting device and with manual assistance, and then moved to the quenching tank. This method is cumbersome and inefficient. In addition, the metal sheet is prone to displacement during the hoisting process, which can cause it to be impacted and deformed. Summary of the Invention

[0015] The advantages and positive effects of this invention are:

[0016] (1) The metal plate is supported by the bearing frame and the limiting frame, and the metal plate is limited by the elastic block and the limiting block II. At the same time, the upper part of the metal plate is limited by the corresponding limiting block I, and the lower part of the metal plate is limited by the corresponding elastic element III and the corresponding elastic element IV. This keeps the metal plate stable and leaves a gap between two adjacent metal plates. This avoids the problem of two adjacent metal plates stacking together when the heating furnace is heating multiple metal plates, which would result in low heating efficiency of the stacked part of the metal plates and uneven and insufficient heating.

[0017] (2) By immersing all the metal plates in the quenching liquid in the quenching tank, the quenching treatment of all the metal plates can be achieved, thereby achieving rapid and portable quenching treatment of all the metal plates and avoiding the problem of deformation caused by impact during the transportation of the metal plates. The quenching effect is improved by controlling the operation of the circulating pump to circulate and cool the quenching liquid in the quenching tank.

[0018] (3) By swinging the metal plate before heating, the rust and adhering impurities on the surface of the metal plate are loosened by the swinging, and the loosened rust and impurities are blown away by the gas, thereby reducing the rust and impurities on the surface of the metal plate and reducing the possibility that the oxide scale will be immersed in the quenching liquid in the quenching pool along with the metal plate.

[0019] (4) By blowing gas onto the metal plate, the metal plate swings between the corresponding support frame and the limit frame, thereby stirring the quenching liquid in the quenching pool through the metal plate, so that the temperature of the quenching liquid in each area is similar, thus avoiding the problem of uneven quenching liquid temperature and affecting the quenching effect caused by the quenching liquid being hot around the metal plate and colder away from the metal plate. In addition, the swinging of the metal plate causes the quenching liquid to fluctuate, thereby washing away the oxide scale generated on the surface of the metal plate, thus reducing the oxide scale adhering to the surface of the metal plate, which would lead to uneven and insufficient quenching of the metal plate.

[0020] (5) High-temperature steam and harmful gases are drawn in through the air port corresponding to the solenoid valve above the round rod and filtered through the air filter, thereby reducing the harm to the health of on-site workers caused by high-temperature steam and harmful gases.

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1:

[0036] It also includes a drive assembly, a fixed box 203, round rods 204, a rectangular frame 205, a support frame 206, a slide rod 207, an elastic element I 208, a winding machine 209, a steel cable 210, a fixing plate 211, and a clamping and limiting assembly; the drive assembly is connected to the heating furnace 2; the drive assembly is connected to the fixed box 203, and the fixed box 203 is equipped with heat insulation material; a round rod 204 is fixed to each of the four rectangular corners of the fixed box 203; a rectangular frame 205 is slidably connected to all the round rods 204; a support frame 206 is slidably connected to all the round rods 204, and the support frame 206 is located below the rectangular frame 205; the support frame 206...

[0037] The clamping and limiting assembly includes a limiting block I 301, a stop block, a limiting block II 303, a fixing rod 304, an elastic element II 305, a support frame 306, and a limiting frame 307. Two limiting blocks I 301 are fixedly connected to the lower surface of the fixing plate 211. An elastic stop block 302 is fixedly connected to the lower surface of the fixing plate 211, and a spring is provided inside the elastic stop block 302. The limiting block II 303 is slidably connected to the fixing plate 211. A fixing rod 304 is fixedly connected to the fixing plate 211. The fixing rod 304 is slidably connected to the limiting block II 303. An elastic element II 305 is sleeved on the outside of the fixing rod 304. The elastic element II 305 is a spring. One end of the elastic element II 305 is fixedly connected to the fixing plate 211, and the other end of the elastic element II 305 is fixedly connected to the limiting block II 303. A support frame 306 is fixedly connected to the lower surface of the fixing plate 211. A limiting frame 307 is fixedly connected to the lower surface of the fixing plate 211.

[0038] The lower part of the stop is designed in a wedge shape to facilitate the quick insertion of the metal sheet 4.

[0039] The lower part of the support frame 306 is provided with a blocking part 3062, and the blocking part 3062 has multiple through holes.

[0040] It also includes a cover plate 2031; the cover plate 2031 is fixedly attached to the fixed box 203, and the cover plate 2031 is made of heat-insulating material.

[0041] It also includes a heat insulation component 2032; the heat insulation component 2032 is fixedly attached to the lower surface of the fixed box 203, and the heat insulation component 2032 has a round hole for the steel cable 210 to move.

[0042] It also includes a ball head 2101; the ball head 2101 is installed on the steel cable 210 to seal the round hole on the heat insulation component 2032 to reduce heat conduction to the winding machine 209.

[0043] It also includes elastic element Ⅲ3061 and elastic element Ⅳ3071; the lower part of the support frame 306 is fixed with two elastic elements Ⅲ3061, which are spring rods Ⅰ; the lower part of the limit frame 307 is fixed with two elastic elements Ⅳ3071, which are spring rods Ⅱ.

[0044] It also includes a circulating pump 11; the circulating pump 11 is installed on the base frame 1; the circulating pump 11 is connected to the quenching tank 3 through a pipeline.

[0045] The drive assembly includes an electric actuator 201 and a heat insulation groove plate 202; two electric actuators 201 are fixedly connected to the inner side of the upper part of the fixed box 203. The electric actuators 201 are multi-stage electric push rods, and the telescopic parts of all electric actuators 201 are fixedly connected to the inner side of the heating furnace 2; two heat insulation groove plates 202 are fixedly connected to the inner side of the heating furnace 2, and each heat insulation groove plate 202 is located outside the telescopic part of the corresponding electric actuator 201.

[0046] During loading: The hatch 21 is opened manually, and then two electric actuators 201 are activated to move the fixed box 203 toward the opening of the heating furnace 2. The movement of the fixed box 203 moves all connected components, which in turn moves all the support frames 306 and limit frames 307, so that all the support frames 306 and limit frames 307 are exposed from inside the heating furnace 2 to facilitate loading. Then, the metal plate 4 is clamped manually or by an external robotic arm and placed onto the corresponding support frame 306 and limit frame 307. The support frame 306 and limit frame 307 work together to support the metal plate 4. During the process of placing the metal plate 4 into the support frame 306, the movement of the metal plate 4 will compress the elastic stop 302, causing the elastic stop to... The stop block 302 contracts under pressure, causing the elastic stop block 302 to press against the upper surface of the metal plate 4, thus stabilizing the metal plate 4 during the feeding process. This pushes the metal plate 4 further until it presses against the blocking part 3062 on the support frame 306. Simultaneously, the upper part of the metal plate 4 presses against the limiting block II 303, causing it to move along the fixed rod 304 and stretch the corresponding elastic element II 305. This causes the limiting block II 303 to press against one side of the metal plate 4. After the entire metal plate 4 has moved past the elastic stop block 302, the elastic stop block 302 will move downwards and reset due to its own elasticity, pressing against the other side of the metal plate 4. Thus, the elastic stop block 302 and the limiting block II 303 work together to limit the movement of the metal plate 4. Figure 5As shown, the upper part of the metal plate 4 is limited by the corresponding limiting block I 301, and the lower part of the metal plate 4 is limited by the corresponding elastic element III 3061 and the corresponding elastic element IV 3071, so that the metal plate 4 remains stable, thus completing the loading operation of one metal plate 4. Then, in the same way, multiple metal plates 4 are placed on the corresponding support frame 306 and limiting frame 307 in sequence, so as to realize the loading and limiting of multiple metal plates 4, thereby leaving a gap between two adjacent metal plates 4, avoiding the problem of stacking two adjacent metal plates 4 when the heating furnace 2 is heating multiple metal plates 4, which would result in low heating efficiency of the stacked part of the metal plates 4 and uneven and insufficient heating.

[0047] When heating multiple metal plates 4: After the metal plates 4 are loaded, the two electric actuators 201 are activated to move and reset the fixed box 203, causing the fixed box 203 to move into the heating furnace 2. The movement of the fixed box 203 causes all connected components to move, which in turn causes all the support frames 306 and limit frames 307 to move, so that all the metal plates 4 are moved into the heating furnace 2. Then, the door 21 of the heating furnace 2 is closed manually, and then the heating furnace 2 is controlled to operate to heat all the metal plates 4. Furthermore, an electromagnetic induction coil 22 is provided between each pair of adjacent metal plates 4, which makes all the metal plates 4 heat up more evenly and fully, thereby improving the heating effect on the metal plates 4. After the fixed box 203 moves and resets, a chamber is formed between the fixed box 203 and the heating furnace 2, which can reduce the heat transfer to the electric actuator 201 and the winding machine 209. In addition, the heat insulation slot plate 202, the cover plate 2031 and the heat insulation component 2032 can further isolate the heat, thereby ensuring that the equipment can operate normally.

[0048] During quenching: When the existing equipment quenches the metal plate 4, after taking the metal plate 4 out of the heating furnace 2, it is necessary to lift the metal plate 4 with the help of an external hoisting device and manual assistance, and then move the metal plate 4 to the quenching tank 3. This method is cumbersome and inefficient. In addition, the metal plate 4 is prone to displacement during the hoisting process, which can cause the metal plate 4 to be deformed due to impact.

[0049] To solve the above problems, after the heating furnace 2 has heated the metal sheet 4, the hatch 21 is opened in the same manner as described above. Then, the two electric actuators 201 are started to move the fixed box 203 towards the opening of the heating furnace 2, so that all the support frames 306 and limit frames 307 are exposed in the heating furnace 2, and all the metal sheets 4 are positioned above the quenching tank 3. Then, the winding machine 209 is started to release the steel cable 210. Under the gravity of all the metal sheets 4, the rectangular frame 205 and the support frame 206 will move downward along all the round rods 204. At the same time, all the fixed plates 211, sliding rods 207 and elastic elements I 208 move downward synchronously until all the metal sheets 4 are exposed. All metal plates 4 are immersed in the quenching liquid in the quenching tank 3, thereby achieving quenching treatment for all metal plates 4 quickly and conveniently, and avoiding deformation of the metal plates 4 due to impact during transportation. The quenching liquid in the quenching tank 3 is circulated and cooled by controlling the operation of the circulating pump 11, thereby improving the quenching effect. After quenching is completed, the winding machine 209 is started to remove all metal plates 4 from the quenching tank 3, and then all metal plates 4 are removed from the corresponding support frame 306 and limit frame 307, and then the next batch of metal plates 4 is put in. The metal plates 4 are quenched in the same way.

[0050] Example 2:

[0051] Based on Example 1, according to Figures 7-11As shown, it also includes a swing system; the swing system is connected to the fixed box 203; the swing system includes a retaining ring I 2041, a retaining ring II 2042, a solenoid valve 2043, an air pump 401, a conduit 402, an air pipe 403, a branch pipe 404, a nozzle 405, a wedge block I 406, a wedge block II 407, and an air filter 408; a retaining ring I 2041 is fixedly connected to each round rod 204; a retaining ring II 2042 is fixedly connected to each round rod 204, and the retaining ring II 2042 is located below the retaining ring I 2041; two solenoid valves 2043 are installed on each round rod 204; two air pumps 401 are fixedly connected to the upper surface of the fixed box 203; each air pump 401... Each exhaust port of 01 is fixedly connected to a conduit 402, and the conduits 402 are diagonally distributed; each conduit 402 is fixedly connected to and connected to a round rod 204; two air pipes 403 are fixedly connected to the support frame 206; all air pipes 403 are fixedly connected to the support frame 206; each air pipe 403 is connected to five branch pipes 404; each branch pipe 404 is fixedly connected to a corresponding fixed plate 211; two nozzles 405 are installed on each branch pipe 404; all nozzles 405 on the same branch pipe 404 are fixedly connected to a corresponding fixed plate 211; two wedge blocks I 406 are fixedly connected to the support frame 206; two wedge blocks II 407 are fixedly connected to the inner wall of the heating furnace 2.

[0052] It also includes an air filter 408; two air filters 408 are fixedly attached to the upper surface of the fixed box 203, and each air filter 408 is connected to the air inlet of a corresponding air pump 401.

[0053] During long-term storage, the surface of the metal plate 4 will rust and be covered with impurities. In the existing technology, the surface of the metal plate 4 is not treated before heating, resulting in a large amount of oxide scale being generated on the surface of the metal plate 4 after heating. This oxide scale will then be immersed in the quenching liquid in the quenching pool 3 along with the metal plate 4. As a result, during the quenching process, the oxide scale will adhere to the surface of the metal plate 4, leading to uneven and insufficient quenching of the metal plate 4.

[0054] To solve the above problems and improve the quenching effect on the metal sheet 4, after all the metal sheets 4 are placed on the corresponding support frame 306 and limit frame 307, before the metal sheets 4 are moved into the heating furnace 2, a gas pump 401 is started to supply gas into a corresponding conduit 402. The gas enters the round rod 204 along the conduit 402 and flows through the solenoid valve 2043. The solenoid valve 2043 delivers the gas to the gas pipe 403. The gas flows along the gas pipe 403 and the branch pipe 404, and finally sprays onto the corresponding metal sheet 4 through the corresponding nozzle 405. This causes the metal sheet 4 to tilt and collide with one side of the support frame 306 and one side of the limit frame 307, and lean against one side of the support frame 306 and one side of the limit frame 307. Figure 11 As shown, another air pump 401 is then started to supply air into a corresponding conduit 402. The gas then flows in the same manner as described above and is sprayed onto the corresponding metal plate 4 through the corresponding nozzle 405. This causes the metal plate 4 to tilt again and impact the other side of the support frame 306 and the other side of the limiting frame 307. This causes the metal plate 4 to swing before heating, thereby loosening the rust and adhering impurities on the surface of the metal plate 4 through the swing. The loosened rust and impurities are then blown away by the gas, thereby reducing the rust and impurities on the surface of the metal plate 4 and reducing the possibility of oxide scale being immersed in the quenching liquid in the quenching pool 3 along with the metal plate 4.

[0055] Furthermore, when the metal sheet 4 is heated and moved into the quenching tank 3, the support frame 206 moves downwards along all the round rods 204 to its limit and then abuts against all the retaining rings II 2042, thereby limiting the support frame 206 through all the retaining rings II 2042. At this time, all the metal sheets 4 are immersed in the quenching liquid in the quenching tank 3. Then, the upper solenoid valve 2043 is controlled to close, and the lower solenoid valve 2043 is controlled to open and close, so that the gas re-enters the gas pipe 403. Then, the metal sheet 4 is blown in the same way as above, so that the metal sheet 4 is in the corresponding support frame 306 and the limit. The oscillation of the frame 307 stirs the quenching liquid in the quenching tank 3 through the metal plate 4, thereby making the temperature of the quenching liquid in each area similar. This avoids the problem of uneven quenching liquid temperature, which affects the quenching effect, where the quenching liquid temperature is high around the metal plate 4 and low further away from the metal plate 4. Furthermore, the oscillation of the metal plate 4 causes the quenching liquid to fluctuate, which washes away the oxide scale generated on the surface of the metal plate 4. This reduces the adhesion of oxide scale to the surface of the metal plate 4, thus preventing uneven and insufficient quenching of the metal plate 4.

[0056] It should be noted that when the metal plate 4 is moved into the heating furnace 2, the support frame 206 moves, causing the two wedge blocks I 406 to move. This causes each of the two wedge blocks I 406 to touch a wedge block II 407, and each of the two wedge blocks I 406 is pressed downward by the wedge block II 407. The movement of the two wedge blocks I 406 together drives the support frame 206 to move. The movement of the support frame 206 causes all the fixing plates 211 to move downward. The movement of each fixing plate 211 causes the corresponding limiting block I 301 to move downward. This causes every two limiting blocks I 301 to move downward and press against the upper surface of the corresponding metal plate 4, thereby limiting the upper surface of the metal plate 4. This prevents the metal plate 4 from swinging during the heating process, which would lead to uneven heat distribution in the heating furnace 2 and uneven heating of the metal plate 4.

[0057] Furthermore, since the metal sheet 4 generates high-temperature steam and harmful gases during quenching, which could endanger the health of on-site workers, when the metal sheet 4 is immersed in the quenching liquid in the quenching pool 3, the upper solenoid valve 2043 is positioned above the quenching liquid. By controlling the lower solenoid valve 2043 to close and the upper solenoid valve 2043 to open, the two air pumps 401 are operated to extract air. At this time, the gas enters the conduit 402 from the upper solenoid valve 2043, and then the high-temperature steam and harmful gases are extracted through the air port in the round rod 204 corresponding to the upper solenoid valve 2043. The gas is then filtered through the air filter 408, thereby reducing the harm caused by the high-temperature steam and harmful gases to the health of on-site workers.

[0058] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
