[0001] The present application relates to the technical field of metal processing and heat treatment, and in particular to a vertical heat treatment equipment furnace body precision molding equipment. Background Art

[0002] In the field of metal processing and heat treatment, vertical heat treatment equipment, as one of the key pieces of equipment, is widely used in a variety of industries, including aerospace, automotive manufacturing, and machinery manufacturing.

Therefore, when workers place workpieces in the furnace, they are likely to be burned. 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

[0005] The present application provides a vertical heat treatment equipment furnace body precision molding equipment adopts the following technical solutions:

[0006] 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 under the furnace body, and a plurality of placement plates are arranged in sequence on the transport component along its transport direction, a sealing plate for placing the workpiece is provided on the placement plate, a positioning member for positioning the sealing plate is provided on the placement 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 the 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.

[0007] By adopting the above technical solution, 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 toward 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 inserted 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 workpiece is heated, 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; it also reduces the possibility of burns to the staff.

[0008] Preferably, the connecting assembly includes 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 fixed to the connecting block and the inner wall of the sealing plate;

[0009] A fixed block is fixedly provided on the side wall of the furnace body, an abutment block is fixedly provided on the fixed block, one end of the connecting block is provided with an inclined surface, the connecting block slides and fits in the abutment block through its inclined surface, and the side of the connecting block away from its inclined surface abuts against the abutment block.

[0010] By adopting the above technical solution, when the sealing plate moves upward, it can drive the connecting block 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 of 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.

[0011] Preferably, the separation assembly includes a push block and a second spring, the push block vertically slides above the fixed block near the side of the abutting block, the push block and the abutting block are provided with inclined surfaces on opposite sides, the connecting block and the abutting block can be slidably fitted to the push block via corresponding inclined surfaces, the push block is slidably fitted to the connecting block via its inclined surfaces, and the width of the push block is greater than the width of the abutting block;

[0012] The second spring is arranged in the fixing block, and two ends of the second spring are fixedly arranged on the pushing block and the inner wall of the fixing block respectively.

[0013] By adopting the above technical solution, when the staff needs to take the workpiece out of the furnace body, they first push the sealing plate through the pushing assembly to drive the connecting block to move upward for a distance. During this period, the connecting block can contact the pushing block, and the pushing block pushes the connecting block to move through the inclined surface on the connecting block until the connecting block moves to the position above the pushing 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 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.

[0014] Preferably, a motor is installed outside the top of the furnace body, a fan is rotatably arranged inside the furnace body, a rotating rod is fixedly arranged at the central axis of the fan, the rotating rod is vertically arranged, and the rotating rod is rotatably arranged on the side wall of the furnace body, and one end of the rotating rod is fixedly arranged on the rotating shaft on the motor.

[0015] By adopting the above technical solution, when the workpiece is heated in the furnace, the motor can be turned on, and the motor can drive the rotating rod to drive the fan to rotate. The operation of the fan can accelerate the circulation of gas in the furnace cavity, so that the heat is more evenly distributed in the furnace body, thereby improving the heating efficiency of the workpiece; at the same time, the rotation of the fan accelerates the gas flow, which helps to reduce the temperature difference between different areas in the furnace body and ensure that the workpiece is heated evenly.

[0016] Preferably, a support plate is fixedly provided on the sealing plate, a top plate is rotatably provided inside the support plate, the workpiece is placed on the top plate, and a rotating assembly for driving the top plate to rotate is provided in the furnace body.

[0017] By adopting the above technical solution, when the workpiece is heated in the furnace body, the fan rotates and the rotating component is triggered at the same time, and the rotating component can drive the top plate to drive the workpiece to rotate; the rotation of the workpiece can ensure that all parts of the workpiece surface can evenly receive the heat in the furnace, and the high-temperature area and 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.

[0018] Preferably, the rotating assembly includes a driving rod 1, a belt, a sleeve, and a driving rod 2, wherein the driving rod 1 is vertically arranged and rotatably arranged on the inner wall of the furnace body; the two ends of the belt are respectively sleeved on the top end of the driving rod 1 and the rotating rod, and the sleeve is sleeved on the bottom end of the driving rod 1; the driving rod 1 is fixedly provided with a guide block 1, and the inner wall of the sleeve is provided with a guide groove for the sliding movement of the guide block 1; the driving rod 1 is provided with a spring 3, and the two ends of the spring 3 are respectively fixedly provided on the driving rod 1 and the sleeve;

[0020] By adopting the above technical solution, when the rotating rod rotates, the belt can drive the driving rod 1 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, and 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. At this time, the sleeve can drive the driving rod 2 to rotate, and the driving rod 2 drives the gear 1 to rotate, and the gear 1 drives the gear 2 to rotate, and the gear 2 drives the top plate and the workpiece to rotate, thereby reducing the difficulty of rotating the top plate and the workpiece.

[0021] Preferably, there are multiple push rods 1 and multiple push rods 2 that slide vertically in the top plate, and the push rod 1 and the push rod 2 rise alternately, and both the push rod 1 and the push rod 2 can abut against the bottom of the workpiece; a first driving component for driving the push rod 1 and the push rod 2 to move is provided in the support plate.

[0022] By adopting the above technical solution, during the rotation of the top plate, the first drive component is triggered, and the first drive 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 contacted 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 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 1 and the top rod 2 helps to circulate air on the surface of the workpiece, reducing the formation of oxide scale.

[0024] By adopting the above technical solution, the top plate drives the driving rod three to rotate together during its rotation, and the driving rod three drives the gear three to rotate along the circumference of the top plate. During this period, the gear four can drive the gear three and the driving rod three to rotate, and the driving rod three simultaneously drives the cam one and the cam two to rotate. The cam one and the cam two can respectively push the push rod one on the slide one and the push rod two on the slide two to move back and forth in the vertical direction. When the push rod one is at the highest point, the push rod two is at the lowest point. Then, when the cam one gradually drives the push rod one to move downward, the cam two gradually drives the push rod two to move upward. This rule is alternated, thereby reducing the difficulty of moving the push rod one and the push rod two.

[0025] Preferably, a plurality of guard plates are fixedly provided on the top plate, a plurality of balls are provided on a side of the guard plate close to the workpiece, and the balls are rolled on the side wall of the workpiece.

[0026] 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 bearings set 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, reducing the possibility of damage to the workpiece.

[0027] Preferably, a preheating barrel is vertically slidable on the ground above the workpiece, with the opening of the preheating barrel facing downward. The preheating barrel can be sleeved on the workpiece, and a second driving component for driving the preheating barrel to move is provided on the ground. A heating component for heating the preheating barrel is provided next to the furnace body.

[0028] By adopting the above technical solution, before the staff pushes the workpiece upward by pushing the assembly, the preheating barrel is located above the next workpiece to be heated. 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.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The staff first places multiple workpieces on the sealing plate on the transport component in sequence, and then the transport component can drive the workpiece to the position corresponding to the opening at the bottom of the furnace body. At this time, the staff can push the sealing plate and the workpiece upward by pushing the 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; when the workpiece is heated, the staff drives the sealing plate and the workpiece downward again by pushing the component, and 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 workload of the staff, and thus improve the overall production efficiency; it also reduces the possibility of burns to the staff;

[0031] 2. When the workpiece is heated in the furnace, the fan rotates and the rotating assembly is triggered, which drives the top plate to rotate the workpiece. The rotation of the workpiece ensures that all parts of the workpiece surface can evenly receive the heat from the furnace. The high-temperature and low-temperature areas on the workpiece will constantly exchange positions, avoiding 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.

[0032] 3. During the rotation of the top plate, the first drive assembly is triggered, and the first drive assembly can drive the first and second push rods to move back and forth alternately in the vertical direction. The first and second push rods 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 contacted with the heat source in the furnace, thereby improving thermal efficiency and heating speed; in addition, since the contact positions of the first and second push rods 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 push 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 first and second push rods helps to circulate air on the surface of the workpiece and reduce the formation of oxide scale.

[0045] 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.

[0046] like Figure 2 and Figure 3 As shown, the sealing plate 4 is provided with a connecting assembly 7 for connecting to the furnace body 1. The connecting assembly 7 is provided in 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.

[0047] 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. 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 slides and fits into 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.

[0048] 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 slides vertically 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 both sides away from each other. 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.

[0049] 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. The second spring 82 is vertically arranged in the fixed block 73, and the upper and lower ends of the second spring 82 are fixedly connected to the slider 83 and the inner wall of the fixed block 73 respectively; 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.

[0050] 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 furnace body 1, and the sealing plates 4 drive the workpieces to move.

[0051] 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.

[0052] like Figure 2 and Figure 3 As shown, when the sealing plate 4 moves upward, it can also drive the connecting block 71 to move. When the sealing plate 4 gradually seals the opening on the furnace body 1, the connecting block 71 can contact the abutment block 74. 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. 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 outward from 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.

[0053] 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. 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 the inclined surface on the pushing block 81. Then, the sealing plate 4 and the workpiece start to move downward through the pushing component 6. At this time, the connecting block When 71 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 1 72 pushes the connecting block 71 to move outward from 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.

[0054] like Figure 2 As shown, the hydraulic cylinder 61 can finally 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.

[0056] 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.

[0058] 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 passes through 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. The inner wall of the sleeve 153 is provided with a guide groove 156 in the vertical direction for the guide blocks 155 to slide; 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. The two ends of the spring 3 157 are respectively fixedly connected to the baffle 158 and the sleeve 153.

[0059] like Figure 5 and Figure 6 As described, the driving rod 2 154 is vertically arranged, and the bottom end thereof is rotatably connected to the top of the support plate 12 through a bearing, and the peripheral side wall of the driving rod 2 154 is fixedly connected with a plurality of guide blocks 2 159, the driving rod 2 154 can be inserted into the sleeve 153, and the guide block 2 159 can be inserted into the guide groove 156; the bottom end of the driving rod 2 154 is sleeved with a gear 160 fixed thereto, and the peripheral side wall of the top plate 14 is sleeved with a gear 2 161 fixed thereto, and the gear 1 160 is meshed with the gear 2 161.

[0060] 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 simultaneously 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. 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.

[0061] 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 and low-temperature areas 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 thermal stress concentration 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.

[0062] 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.

[0063] like Figure 5As shown, the first driving assembly 19 includes a driving rod 3 191, which is horizontally penetrated by the top plate 14 and is rotatably connected to the inner wall of the top plate 14. Both ends of the driving rod 3 191 are located in the storage groove 13; a gear 3 192 is provided in the storage groove 13, and the gear 3 192 is a crown gear. The gear 3 192 is fixedly connected to the bottom of the support plate 12, and the top plate 14 is located in the center through-hole of the gear 3 192. 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 provided in the top plate 14 for rotation. 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 sliding in the top plate 14, slide plate 196 and slide plate 2 197 are both annular plates, the bottom end of push rod 17 is fixedly connected to the top of slide plate 196, the bottom end of push 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.

[0064] like Figure 4 and Figure 5 As shown, during the rotation of the top plate 14, the top plate 14 drives the driving rod three 191 to rotate together, 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. 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 ejector rod one 17 on the slide one 196 and the ejector rod two 18 on the slide two 197 to move back and forth in the vertical direction. When the ejector rod one 17 is at the highest point, the ejector rod two 18 is at the lowest point. Then, when the cam one 194 gradually drives the ejector rod one 17 to move downward, the cam two 195 gradually drives the ejector rod two 18 to move upward. This rule is alternated, and the ejector rod one 17 and the ejector rod two 18 move back and forth alternately in the vertical direction. The ejector rod one 17 and the ejector rod two 18 can repeatedly lift the workpiece.

[0065] 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 contacted 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 due to 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, reducing the formation of oxide scale.

[0066] like Figure 4 and Figure 5 As shown, there are multiple guard plates 20 sliding horizontally along the top plate 14, and 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 provided 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.

[0067] 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 moves back and forth 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.

[0068] like Figure 7 As shown, a preheating barrel 27 is vertically slidably provided on the ground above the workpiece. 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 arranged. A guide plate 29 is fixedly connected to the side wall of the preheating barrel 27. The guide rod 28 passes 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 in front of the furnace body 1. A second driving assembly 30 for driving the preheating barrel 27 to move is provided on the ground.

[0069] like Figure 1 and Figure 7 As shown, the second drive assembly 30 includes a rack 1 301 and a rack 2 302, the side wall of the piston rod on the hydraulic cylinder 61 is fixedly connected to the 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 the gear 5 304, the side wall of the preheating barrel 27 is fixedly connected to the 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 engaged with the gear 5 304.

[0070] 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 the two 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.

[0071] like Figure 1 、 Figure 2 and Figure 3 As shown, before the staff pushes the workpiece upward by pushing the assembly 6, the preheating barrel 27 is located above the next workpiece to be heated. 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 the connecting plate 2 303 and the rack 1 301 to move upward, the rack 1 301 drives the gear 5 304 to rotate, the gear 5 304 drives the rack 2 302 and the connecting plate 3 305 to move downward, and the connecting plate 3 305 drives the preheating barrel 27 to move downward until the preheating barrel 27 is completely placed on the next workpiece to be heated.

[0072] 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. The staff can turn on the pump body 312, and the pump body 312 can circulate the water in the water tank 311 in the water pipe 313. 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 occurrence of cracks.

[0073] 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 the 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 inserted 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 workpiece is heated, 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 burns to the staff.

[0074] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
