These industries have extremely high requirements on the physical, chemical and mechanical properties of metal materials. Therefore, the performance and precision of heat treatment equipment directly affect the quality and performance of the final product.
[0003] In the prior art, heat treatment equipment operates at high temperature, and there is a large temperature difference between the inside and outside of the furnace. Therefore, when workers place workpieces in the furnace, they are likely to be scalded. In addition, for some heavy workpieces, workers need to expend a lot of physical strength to place the workpieces in the furnace, which increases work intensity and reduces work efficiency. Summary of the invention
[0004] In order to reduce the possibility of workers being scalded, and also reduce the work intensity of the workers, thereby improving work efficiency, the present application provides a vertical heat treatment equipment furnace body precision molding equipment.
[0005] The vertical heat treatment equipment furnace body precision molding equipment provided in this application adopts the following technical solutions: A vertical heat treatment equipment furnace body precision forming equipment, including a furnace body arranged on the ground, an opening for workpieces to enter and exit is opened at the bottom of the furnace body, a transport component for transporting workpieces is arranged below the furnace body, a plurality of placing plates are arranged in sequence on the transport component along its transport direction, a sealing plate for placing the workpieces is arranged on the placing plate, a positioning member for positioning the sealing plate is provided on the placing plate, and a sealing member for sealing the bottom opening of the furnace body is provided on the sealing plate; a pushing component for pushing the workpiece to move in a vertical direction is also provided on the ground below the furnace body; a connecting component for connecting the furnace body is provided on the sealing plate, and a separation component for separating the sealing plate from the furnace body is also provided on the furnace body.
[0006] By adopting the above technical scheme, the staff first places multiple workpieces on the sealing plate on the transport component in sequence, and then the transport component can drive the placement plate and the sealing plate to move in the direction close to the furnace body, and the sealing plate drives the workpiece to move. When the workpiece moves to the position corresponding to the opening at the bottom of the furnace body, the staff can push the sealing plate and the workpiece upward through the pushing component until the workpiece is completely located in the furnace body. At this time, the sealing plate is plugged into the opening of the furnace body, and the furnace body is sealed. At this time, the sealing plate is connected to the furnace body under the action of the connecting component; when the heating of the workpiece is completed, the staff drives the sealing plate and the workpiece downward again through the pushing component, the separation component can be triggered, and the sealing plate is separated from the furnace body; finally, the pushing component can place the sealing plate and the workpiece on the corresponding placement plate again, and then the workpiece is transported to the next node for the next processing operation. The whole process can reduce the time and cost of manual operation, reduce the work intensity of the staff, and thus improve the overall production efficiency; at the same time, it also reduces the possibility of scalding the staff.
[0007] Preferably, the connecting assembly comprises a connecting block and a spring 1, wherein the connecting block slides in the sealing plate; the spring 1 is arranged in the sealing plate, and its two ends are respectively fixedly arranged on the connecting block and the inner wall of the sealing plate; A fixing block is fixedly arranged on the side wall of the furnace body, an abutment block is fixedly arranged on the fixing block, an inclined surface is arranged at one end of the connecting block, the connecting block is slidably matched with the abutment block through its inclined surface, and the side of the connecting block away from its inclined surface abuts against the abutment block.
[0008] By adopting the above technical solution, when the sealing plate moves upward, the connecting block can be driven to move at the same time. When the sealing plate gradually seals the opening on the furnace body, the connecting block can contact the abutment block, and then the abutment block can gradually push the connecting block to move into the sealing plate through the inclined surface on the connecting block. The spring 1 is compressed. When the connecting block moves to the position above the abutment block, the elastic force of the spring 1 can push the connecting block to move outward from the sealing plate. At this time, the bottom of the connecting block abuts against the top of the abutment block, thereby reducing the possibility of separation between the sealing plate and the furnace body.
[0009] Preferably, the separation assembly includes a push block and a second spring, the push block vertically slides to an upper position of the fixed block close to the side of the abutment block, the push block and the abutment block are provided with inclined surfaces on opposite sides, the connection block and the abutment block can be slidably matched with the push block through corresponding inclined surfaces, the push block is slidably matched with the connection block through its inclined surface, and the width of the push block is greater than the width of the abutment block; The second spring is arranged in the fixing block, and two ends of the second spring are respectively fixedly arranged on the pushing block and the inner wall of the fixing block.

At this time, the elastic force of spring 1 pushes the connecting block to abut the inclined surface on the pushing block, and then the sealing plate and the workpiece are driven downward by the pushing assembly. At this time, when the connecting block moves downward, it can simultaneously push the pushing block to move downward. When the pushing block abuts against the abutting block, the connecting block continues to move downward, and the pushing block can gradually push the connecting block into the sealing plate through the inclined surface. Then, when the connecting block moves away from the pushing block, the elastic force of spring 1 pushes the connecting block to move out of the sealing plate. At this time, the connecting block contacts the inclined surface at the bottom of the abutting block, and then gradually moves away from the abutting block, thereby separating the sealing plate from the furnace body, making it easier to take the workpiece out of the furnace body.

[0016] By adopting the above technical solution, when the rotating rod rotates, the driving rod 1 can be driven by the belt to rotate, and the driving rod 1 drives the sleeve to rotate. When the sealing plate drives the support plate to move upward, the support plate simultaneously drives the driving rod 2 and the guide block 2 to move upward. When the guide block 2 does not correspond to the guide groove in the sleeve, the driving rod 2 drives the guide block 2 to continue to move upward, and the guide block 2 can push the sleeve compression spring 2 to move. Then, when the sleeve rotates until the guide block 2 corresponds to the guide groove in the sleeve, the elastic force of the spring 2 can push the sleeve to move downward, the driving rod 2 is inserted in the sleeve, and the guide block 2 is inserted in the guide groove on the inner wall of the sleeve.

[0018] By adopting the above technical scheme, during the rotation of the top plate, the first driving component is triggered, and the first driving component can drive the top rod 1 and the top rod 2 to move back and forth alternately in the vertical direction. The top rod 1 and the top rod 2 can repeatedly lift the workpiece, thereby reducing the contact area between the bottom of the workpiece and the top plate, so that the bottom of the workpiece can be better in contact with the heat source in the furnace, thereby improving the thermal efficiency and heating speed; in addition, since the contact positions of the top rod 1 and the top rod 2 with the bottom of the workpiece are different, the bottom of the workpiece can be heated more evenly, avoiding the situation where a certain position at the bottom of the workpiece is in contact with a certain top rod for a long time, resulting in insufficient heating, and reducing deformation of the workpiece due to uneven contact; in addition, the workpiece may be oxidized during the heating process, and the alternating rise of the top rod 1 and the top rod 2 helps to circulate air on the surface of the workpiece and reduce the formation of oxide scale.

The cam one and the cam two can respectively push the top rod one on the slide plate one and the top rod two on the slide plate two to reciprocate in the vertical direction. When the top rod one is at the highest point, the top rod two is at the lowest point. Then, when the cam one gradually drives the top rod one to move downward, the cam two gradually drives the top rod two to move upward. This rule is alternated, thereby reducing the difficulty of moving the top rod one and the top rod two.

[0022] By adopting the above technical solution, the guard plate can support the workpiece, thereby reducing the possibility of the workpiece being offset when rotating in the furnace body; since the workpiece moves back and forth in the vertical direction on the top plate, the ball rollers arranged on the guard plate are connected to the surface of the workpiece, thereby reducing the friction between the workpiece and the guard plate when the workpiece moves in the vertical direction, thereby reducing the possibility of damage to the workpiece.

Then, when the workpiece moves upward, the second drive assembly can be triggered, and the second drive assembly drives the preheating barrel to move downward until it is completely mounted on the next workpiece to be heated. Then, the preheating barrel can increase the temperature inside the barrel under the action of the heating assembly, so that the next workpiece to be processed can be preheated, so that the temperature distribution of the workpiece during the subsequent heating process in the furnace body is more uniform, reducing the thermal stress caused by the temperature gradient, helping to reduce the deformation of the workpiece during the subsequent heating and cooling process, and reducing the occurrence of cracks.
[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1.

[0031] like Figure 2 As shown, a pushing assembly 6 for pushing the workpiece to move in the vertical direction is also provided on the ground below the furnace body 1. The pushing assembly 6 includes a hydraulic cylinder 61 and a push plate 62. The piston rod on the hydraulic cylinder 61 is vertically arranged, and the push plate 62 is fixedly arranged on the top of the piston rod on the hydraulic cylinder 61. A through hole for the push plate 62 to pass through is opened at the bottom of the placing plate 3, and the push plate 62 can abut against the bottom of the sealing plate 4.
[0032] like Figure 2 and Figure 3 As shown, the sealing plate 4 is provided with a connecting assembly 7 for connecting the furnace body 1, and the connecting assembly 7 is provided with four groups. The connecting assembly 7 includes a connecting block 71 and a spring 72. The connecting block 71 slides horizontally in the sealing plate 4; the spring 72 is horizontally arranged in the sealing plate 4, and its two ends are respectively fixed to the connecting block 71 and the inner wall of the sealing plate 4.
[0033] like Figure 2 and Figure 3 As shown, four fixed blocks 73 are fixedly connected to the bottom side wall of the furnace body 1, and the four fixed blocks 73 are arranged in a one-to-one correspondence with the four groups of connecting components 7. Abutment blocks 74 are fixedly connected to the fixed blocks 73. The top of the connecting block 71 away from the sealing plate 4 is provided with an inclined surface. The connecting block 71 is slidably engaged with the abutment block 74 through its inclined surface, and the side of the connecting block 71 away from its inclined surface abuts against the top of the abutment block 74.
[0034] like Figure 2 and Figure 3 As shown, the fixed block 73 is also provided with a separation component 8 for separating the sealing plate 4 from the furnace body 1. The separation component 8 includes a push block 81 and a spring 82. The push block 81 vertically slides to the upper position of the fixed block 73 close to the side of the abutment block 74, and the width of the push block 81 is greater than the width of the abutment block 74. The push block 81 and the abutment block 74 are provided with inclined surfaces on the opposite sides. The push block 81 and the abutment block 74 can be slidably matched with the connecting block 71 through the corresponding inclined surfaces, and the connecting block 71 is slidably matched with the push block 81 through its inclined surfaces.
[0035] like Figure 2 and Figure 3As shown, a slider 83 is fixedly connected to one side of the push block 81, and the slider 83 slides vertically in the fixed block 73. A spring 82 is vertically arranged in the fixed block 73, and the upper and lower ends of the spring 82 are respectively fixedly connected to the slider 83 and the inner wall of the fixed block 73; a guide rod 84 is vertically arranged at the bottom of the slider 83, and the top of the guide rod 84 is fixedly connected to the bottom of the slider 83, and the guide rod 84 slides vertically on the inner wall of the fixed block 73.
[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the staff first places multiple sealing plates 4 in sequence in the positioning ring plates 5 on the corresponding placement plates 3, and then places multiple heated workpieces on each sealing plate 4 in sequence. Then the driving motor 24 can drive the conveyor belt 22 to transmit, and the conveyor belt 22 drives the placement plates 3 and the sealing plates 4 to move toward the direction close to the furnace body 1, and the sealing plates 4 drive the workpieces to move.
[0037] like Figure 2 As shown, when the workpiece moves to the position corresponding to the opening at the bottom of the furnace body 1, the staff turns on the hydraulic cylinder 61, and the piston rod on the hydraulic cylinder 61 drives the push plate 62 to move upward, and then the push plate 62 pushes the sealing plate 4 and the workpiece upward until the workpiece is completely located in the furnace body 1. At this time, the sealing plate 4 is inserted into the opening of the furnace body 1, and the furnace body 1 is sealed.
[0038] like Figure 2 and Figure 3 As shown, when the sealing plate 4 moves upward, the connecting block 71 can be driven to move at the same time. When the sealing plate 4 gradually seals the opening on the furnace body 1, the connecting block 71 can contact the abutment block 74, and then the abutment block 74 can gradually push the connecting block 71 to move into the sealing plate 4 through the inclined surface on the connecting block 71, and the spring 1 72 is compressed. When the connecting block 71 moves to the position above the abutment block 74, the elastic force of the spring 1 72 can push the connecting block 71 to move out of the sealing plate 4. At this time, the bottom of the connecting block 71 abuts against the top of the abutment block 74, thereby reducing the possibility of separation between the sealing plate 4 and the furnace body 1.
[0039] like Figure 2 and Figure 3As shown, when the workpiece is heated, the staff needs to take the workpiece out of the furnace body 1. First, the sealing plate 4 is pushed by the hydraulic cylinder 61 to drive the connecting block 71 to move upward for a distance. During this period, the connecting block 71 can contact the pushing block 81, and the pushing block 81 pushes the connecting block 71 to move through the inclined surface on the connecting block 71 until the connecting block 71 moves to the position above the pushing block 81. At this time, the elastic force of the spring 1 72 pushes the connecting block 71 to abut against the inclined surface on the pushing block 81, and then the sealing plate 4 and the workpiece start to move downward through the pushing component 6. At this time, the connecting block When the push block 81 moves downward, it can simultaneously push the push block 81 to move downward. When the push block 81 abuts against the abutting block 74, the connecting block 71 continues to move downward, and the push block 81 can gradually push the connecting block 71 to move into the sealing plate 4 through the inclined surface. Then, when the connecting block 71 moves away from the push block 81, the elastic force of the spring 72 pushes the connecting block 71 to move out of the sealing plate 4. At this time, the connecting block 71 contacts the inclined surface at the bottom of the abutting block 74, and then gradually moves away from the abutting block 74, thereby separating the sealing plate 4 from the furnace body 1, thereby facilitating the removal of the workpiece from the furnace body 1.
[0040] like Figure 2 As shown, finally the hydraulic cylinder 61 can place the sealing plate 4 and the workpiece on the corresponding placement plate 3 again, and then the workpiece is transported to the next node for the next processing operation. The whole process can reduce the time and cost of manual operation, reduce the work intensity of the staff, and thus improve the overall production efficiency; it also reduces the possibility of the staff being burned.
[0041] like Figure 4 As shown, a motor 9 is installed on the outside of the top of the furnace body 1 by bolts, and the rotating shaft on the motor 9 is arranged vertically downward. A fan 10 is rotatably arranged in the furnace body 1, and a rotating rod 11 is fixedly connected to the central axis of the fan 10. The rotating rod 11 vertically penetrates the top side wall of the furnace body 1, and the rotating rod 11 is rotatably sealed to the top of the furnace body 1, and the top end of the rotating rod 11 is fixedly connected to the rotating shaft on the motor 9.
[0042] like Figure 4 As shown, when the workpiece is heated in the furnace body 1, the motor 9 can be turned on, and the motor 9 can drive the rotating rod 11 to drive the fan 10 to rotate. The operation of the fan 10 can accelerate the circulation of gas in the furnace cavity, so that the heat is more evenly distributed in the furnace body 1, thereby improving the heating efficiency of the workpiece; at the same time, the rotation of the fan 10 accelerates the gas flow, which helps to reduce the temperature difference between different areas in the furnace body 1 and ensure that the workpiece is heated evenly.
[0043] like Figure 4 and Figure 5As shown, a support plate 12 is fixedly connected to the top of the sealing plate 4, a storage groove 13 is provided on the top of the support plate 12, the storage groove 13 extends in the vertical direction, a top plate 14 is arranged in the storage groove 13, the top plate 14 is in the shape of a circular plate, the top plate 14 is rotatably connected to the inner wall of the support plate 12, the workpiece is placed on the top plate 14, and a rotating component 15 for driving the top plate 14 to rotate is provided in the furnace body 1.
[0044] like Figure 4 and Figure 6 As shown, the rotating assembly 15 includes a driving rod 151, a belt 152, a sleeve 153 and a driving rod 2 154. The driving rod 151 is vertically arranged and penetrates the top side wall of the furnace body 1. The driving rod 151 is rotatably sealed to the top side wall of the furnace body 1; the belt 152 is arranged outside the top of the furnace body 1, and the two ends of the belt 152 are respectively sleeved on the top of the driving rod 151 and the rotating rod 11; the sleeve 153 is vertically arranged in the furnace body 1, and the sleeve 153 is sleeved on the bottom end of the driving rod 151. A plurality of guide blocks 155 are fixedly connected to the side wall around the bottom end of the driving rod 151, and a guide groove 156 for the guide block 155 to slide is opened on the inner wall of the sleeve 153 in the vertical direction; a spring 3 157 is sleeved on the driving rod 151, and a baffle 158 is fixedly connected to the side wall of the driving rod 151, and the two ends of the spring 3 157 are respectively fixedly connected to the baffle 158 and the sleeve 153.
[0045] like Figure 5 and Figure 6 The driving rod 154 is vertically arranged, and its bottom end is rotatably connected to the top of the support plate 12 through a bearing, and a plurality of guide blocks 159 are fixedly connected to the peripheral side wall of the driving rod 154. The driving rod 154 can be inserted into the sleeve 153, and the guide block 159 can be inserted into the guide groove 156; a gear 160 is fixedly sleeved on the bottom end of the driving rod 154, and a gear 2 161 is fixedly sleeved on the peripheral side wall of the top plate 14, and the gear 160 is meshed with the gear 2 161.
[0046] like Figure 4 , Figure 5 and Figure 6As shown, when the workpiece is heated in the furnace body 1, the rotating rod 11 drives the fan 10 to rotate. At the same time, the rotating rod 11 can drive the driving rod 151 to rotate through the belt 152, and the driving rod 151 drives the sleeve 153 to rotate. When the sealing plate 4 drives the support plate 12 to move upward, the support plate 12 drives the driving rod 2 154 and the guide block 2 159 to move upward together. When the guide block 2 159 does not correspond to the guide groove 156 in the sleeve 153, the driving rod 2 154 drives the guide block 2 159 to continue to move upward, and the guide block 2 159 can push the sleeve 153 to compress the spring 3 157 to move upward. The sleeve 153 is moved, and then when the sleeve 153 rotates to the point where the guide block 2 159 corresponds to the guide groove 156 in the sleeve 153, the elastic force of the spring 3 157 can push the sleeve 153 to move downward, the driving rod 2 154 is inserted into the sleeve 153, and the guide block 2 159 is inserted into the guide groove 156 on the inner wall of the sleeve 153. At this time, the sleeve 153 can drive the driving rod 2 154 to rotate, the driving rod 2 154 drives the gear 1 160 to rotate, the gear 1 160 drives the gear 2 161 to rotate, and the gear 2 161 drives the top plate 14 and the workpiece to rotate, thereby reducing the difficulty of rotating the top plate 14 and the workpiece.
[0047] like Figure 4 As shown, the rotation of the workpiece can ensure that all parts of the workpiece surface can evenly receive the heat in the furnace. The high-temperature area and the low-temperature area on the workpiece will constantly exchange positions to avoid local overheating or overcooling, thereby reducing the temperature difference inside the workpiece and making the overall temperature more uniform. At the same time, it helps to reduce the concentration of thermal stress caused by uneven temperature and improve the processing quality and performance of the workpiece. Uniform heating and rapid heat transfer can shorten the heating time, improve thermal efficiency and reduce energy consumption.
[0048] like Figure 5 As shown, there are multiple push rods 17 and multiple push rods 18 that slide vertically in the top plate 14. The push rods 17 and 18 rise alternately, and both the push rods 17 and 18 can abut against the bottom of the workpiece; a first driving component 19 is provided in the support plate 12 for driving the push rods 17 and 18 to move.
[0049] like Figure 5As shown, the first driving assembly 19 includes a driving rod 3 191, which is horizontally penetrated in the top plate 14 and rotatably connected to the inner wall of the top plate 14, and both ends of the driving rod 3 191 are located in the storage slot 13; a gear 3 192 is arranged in the storage slot 13, and the gear 3 192 is a crown gear, and the gear 3 192 is fixedly connected to the bottom of the support plate 12, and the top plate 14 is located in the central through hole of the gear 3 192, and both ends of the driving rod 3 191 are sleeved and fixed with a gear 4 193, and the gear 3 192 is meshed with the gear 4 193; a cam is rotatably arranged in the top plate 14 Cam 1 194 and cam 2 195 are both vertically arranged, and cam 194 and cam 2 195 are both sleeved and fixed on driving rod 3 191; slide plate 196 and slide plate 2 197 are vertically slidable in the top plate 14, slide plate 196 and slide plate 2 197 are both annular plate-shaped, the bottom end of top rod 17 is fixedly connected to the top of slide plate 196, the bottom end of top rod 2 18 is fixedly connected to the top of slide plate 2 197, the peripheral side wall of cam 194 is slidably connected to slide plate 196, and cam 2 195 is slidably connected to slide plate 2 197.
[0050] like Figure 4 and Figure 5 As shown, during the self-rotation of the top plate 14, the top plate 14 drives the driving rod three 191 to rotate together during the rotation process, and the driving rod three 191 drives the gear three 192 to rotate along the circumference of the top plate 14. During this period, the gear four 193 can drive the gear three 192 and the driving rod three 191 to rotate, and the driving rod three 191 simultaneously drives the cam one 194 and the cam two 195 to rotate. The cam one 194 and the cam two 195 can respectively push the top rod one 17 on the slide one 196 and the top rod two 18 on the slide two 197 to reciprocate in the vertical direction. When the top rod one 17 is at the highest point, the top rod two 18 is at the lowest point at this time. Then, when the cam one 194 gradually drives the top rod one 17 to move downward, the cam two 195 gradually drives the top rod two 18 to move upward. This rule is alternated, and the top rod one 17 and the top rod two 18 move back and forth alternately in the vertical direction. The top rod one 17 and the top rod two 18 can repeatedly lift the workpiece.
[0051] like Figure 4 and Figure 5 As shown, the contact area between the bottom of the workpiece and the top plate 14 is reduced, so that the bottom of the workpiece can be better in contact with the heat source in the furnace, thereby improving the thermal efficiency and heating speed; in addition, since the contact positions of the top rod 17 and the top rod 2 18 with the bottom of the workpiece are different, the bottom of the workpiece can be heated more evenly, avoiding the situation where a certain position of the bottom of the workpiece is in contact with a certain top rod for a long time, resulting in insufficient heating, and reducing the deformation of the workpiece caused by uneven contact; in addition, the workpiece may be oxidized during the heating process, and the alternating rise of the top rod 17 and the top rod 2 18 helps to circulate air on the surface of the workpiece and reduce the formation of oxide scale.
[0052] like Figure 4 and Figure 5 As shown, a plurality of guard plates 20 are horizontally slidable on the upper edge of the top plate 14, a connecting plate 25 is fixedly connected to the guard plate 20, the connecting plate 25 is vertically arranged, and the bottom of the connecting plate 25 is fixedly connected to the top of the top plate 14; a plurality of balls 26 are arranged on the side of the guard plate 20 close to the workpiece, and the balls 26 are rollingly connected to the side wall of the workpiece.
[0053] like Figure 4 and Figure 5 As shown, the guard plate 20 provided can support the workpiece, thereby reducing the possibility of the workpiece being offset when rotating in the furnace body 1; since the workpiece reciprocates in the vertical direction on the top plate 14, the balls 26 provided on the guard plate 20 are rollingly connected to the surface of the workpiece, thereby reducing the friction between the workpiece and the guard plate 20 when the workpiece moves in the vertical direction, thereby reducing the possibility of damage to the workpiece.
[0054] like Figure 7 As shown, a preheating barrel 27 is vertically slidably disposed above the workpiece on the ground, a guide rod 28 is fixed to one side of the furnace body 1 close to the preheating barrel 27, the guide rod 28 is vertically disposed, a guide plate 29 is fixedly connected to the side wall of the preheating barrel 27, the guide rod 28 is passed through the guide plate 29, the opening of the preheating barrel 27 faces downward, the preheating barrel 27 can be sleeved on the workpiece to be heated located in front of the furnace body 1, and a second driving assembly 30 for driving the preheating barrel 27 to move is disposed on the ground. like Figure 1 and Figure 7 As shown, the second driving assembly 30 includes a rack 1 301 and a rack 2 302, the piston rod side wall on the hydraulic cylinder 61 is fixedly connected to a connecting plate 2 303, the rack 1 301 is vertically arranged, and the bottom end of the rack 1 301 is fixedly connected to the connecting plate 2 303, the side wall of the furnace body 1 is rotatably connected to a gear 5 304, the side wall of the preheating barrel 27 is fixedly connected to a connecting plate 3 305, the rack 2 302 is vertically arranged, and the rack 2 302 is fixedly connected to the connecting plate 3 305, and the rack 1 301 and the rack 2 302 are both meshed with the gear 5 304.
[0055] like Figure 1 and Figure 7 As shown, a heating component 31 for heating the preheating barrel 27 is provided next to the furnace body 1. The heating component 31 includes a water tank 311, a pump body 312 and a water pipe 313. One side wall of the water tank 311 is fixedly connected to one side of the exhaust pipe of the furnace body 1. The pump body 312 is installed in the water tank 311. The water pipe 313 is fixed around the inner wall of the preheating barrel 27, and both ends of the water pipe 313 are respectively connected to the water outlet of the pump body 312 and the inner cavity of the water tank 311, and the water inlet of the pump body 312 is connected to the inner cavity of the water tank 311.
[0056] like Figure 1 , Figure 2 and Figure 3 As shown, before the staff pushes the workpiece upward by pushing assembly 6, the preheating barrel 27 is located above the next workpiece to be heated, and then when the piston rod on the hydraulic cylinder 61 drives the workpiece upward, the piston rod on the hydraulic cylinder 61 can simultaneously drive connecting plate 2 303 and rack 1 301 to move upward, rack 1 301 drives gear 5 304 to rotate, gear 5 304 drives rack 2 302 and connecting plate 3 305 to move downward, and connecting plate 3 305 drives the preheating barrel 27 to move downward until the preheating barrel 27 is completely mounted on the next workpiece to be heated.
[0057] like Figure 1 and Figure 2 As shown, the heat of the exhaust gas discharged from the furnace body 1 can heat the water in the water tank 311, and the staff can turn on the pump body 312. The pump body 312 can circulate the water in the water tank 311 in the water pipe 313, and the preheating barrel 27 can be heated, so that the waste heat generated in the furnace body 1 can be recycled to improve energy utilization efficiency and reduce energy consumption. The preheating barrel 27 can preheat the next workpiece to be processed, so that the temperature distribution of the workpiece during the subsequent heating process in the furnace body 1 can be more uniform, reducing the thermal stress caused by the temperature gradient, helping to reduce the deformation of the workpiece during the subsequent heating and cooling process, and reducing the generation of cracks.
[0058] The implementation principle of the embodiment of the present application is as follows: the staff first places multiple workpieces on the sealing plate 4 on the transport component 2 in sequence, and then the transport component 2 can drive the placement plate 3 and the sealing plate 4 to move in the direction close to the furnace body 1, and the sealing plate 4 drives the workpiece to move. When the workpiece moves to a position corresponding to the opening at the bottom of the furnace body 1, the staff can push the sealing plate 4 and the workpiece upward through the pushing component 6 until the workpiece is completely located in the furnace body 1. At this time, the sealing plate 4 is plugged into the opening of the furnace body 1, and the furnace body 1 is sealed. At this time, the sealing plate 4 is connected to the furnace body 1 under the action of the connecting component 7; when the heating of the workpiece is completed, the staff drives the sealing plate 4 and the workpiece downward again through the pushing component 6, and the separation component 8 can be triggered, and the sealing plate 4 is separated from the furnace body 1; finally, the pushing component 6 can place the sealing plate 4 and the workpiece on the corresponding placement plate 3 again, and then the workpiece is transported to the next node for the next processing operation. The whole process can reduce the time and cost of manual operation, reduce the work intensity of the staff, and thus improve the overall production efficiency; at the same time, it also reduces the possibility of scalding the staff.
[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
