Description

Technical Field

[0001] This application relates to the technical field of metal melting, and particularly relates to a heating furnace. Background Art

[0002] In the field of metal material processing and production, a heating furnace is a basic and key equipment. The main function of the heating furnace is to heat metal raw materials or semi-finished products to the required precise temperature to ensure that they can meet the strict requirements of subsequent processes.

[0003] However, the operation mode of traditional heating furnaces has some obvious limitations. For example, the operator has to manually open and close the furnace door repeatedly. This repetitive labor not only consumes time, but also easily leads to safety hazards during manual operation due to the high temperature of the furnace door. In addition, the operator also needs to directly put the materials into the heating furnace or take out the heated materials from the furnace, which undoubtedly increases the work intensity and also brings potential safety hazards. Summary of the Utility Model

[0004] In view of the above, it is necessary to propose a heating furnace that can automatically open or close the furnace door, and drive the telescopic component of the loading mechanism through the rack on the furnace door. It can drive the telescopic component to move when opening the door to extend the loading plate out of the heating chamber, and drive the telescopic component to move when closing the door to retract the loading plate into the heating chamber.

[0005] An embodiment of the present application provides a heating furnace, including: a furnace body provided with a heating chamber having a material discharge opening; a closing mechanism connected to the furnace body and including a driving assembly disposed on the front side of the furnace body, a furnace door connected to the driving assembly and covering the material discharge opening, and a rack connected to the side of the furnace door facing the heating chamber. The driving assembly drives the furnace door to move from the material discharge opening to a first position in a first direction, and drives the furnace door to move from the first position to a second position in a second direction perpendicular to the first direction; a material loading mechanism disposed in the heating chamber, including a telescopic assembly disposed in the heating chamber and a material loading plate connected to the telescopic assembly. The telescopic assembly includes a cross telescopic arm disposed in the heating chamber, a gear disposed near the material discharge opening, and a traction rod connected to the gear and the cross telescopic arm. One end of the cross telescopic arm away from the material discharge opening is fixed in the heating chamber, and one end of the cross telescopic arm near the material discharge opening is connected to the material loading plate to carry the material loading plate; wherein, when the furnace door is in the first position, the rack is opposite to the gear in the second direction. When the furnace door moves from the first position to the second position, the rack meshes with the gear and drives the gear to rotate. The gear drives the traction rod to move, and the traction rod drives one end of the cross telescopic arm near the material discharge opening to extend out of the heating chamber, thereby extending the material loading plate out of the heating chamber.

[0006] In the above heating furnace, the material can be heated through the heating chamber in the furnace body, and the furnace door can be automatically opened or closed through the closing mechanism. The driving assembly of the closing mechanism can drive the furnace door to move from the material discharge opening to the first position, and drive the furnace door to move from the first position to the second position to open the furnace door. When the furnace door moves from the first position to the second position, the rack on the furnace door meshes with the gear of the material loading mechanism, thereby causing the gear to rotate. The gear drives the telescopic assembly to move to extend the material loading plate out of the heating chamber when the furnace door is opened. When the driving assembly drives the furnace door to move from the second position to the first position, the rack meshes with the gear, the gear drives the telescopic assembly to move, and the telescopic assembly drives the material loading plate to move into the heating chamber. Then the driving assembly drives the furnace door to move from the first position to the material discharge opening to close the furnace door. The above heating furnace can drive the telescopic assembly to extend the material loading plate out of the heating chamber when opening the furnace door, and drive the telescopic assembly to retract the material loading plate into the heating chamber when closing the furnace door, with high working efficiency and high safety.

The driving member drives the first connecting rod to move along the first sliding track to drive the other ends of the two second connecting rods away from the first connecting rod to move along the corresponding second sliding tracks respectively. When the second connecting rod moves away from the material discharging opening along the closing track, the second connecting rod drives the furnace door to move from the material discharging opening to the first position. When the second connecting rod moves along the downward moving track, the second connecting rod drives the furnace door to move from the first position to the second position.

[0091] The operation process of opening and closing the furnace door 22 of the heating furnace 100 provided by the embodiment of the present application is generally as follows: When opening the furnace door 22, please refer to Figure 5 and Figure 6 , the driving member 212 drives the first link 213 to slide downward along the first slideway 2111. The first link 213 pulls the corresponding two second links 214 to move. One end of the second link 214 connected to the closing slideway 2112b first moves away from the discharging opening 12 along the closing slideway 2112b. At this time, the second link 214 drives the furnace door 22 to move away from the discharging opening 12 in the X-axis direction, so that the furnace door 22 moves from the discharging opening 12 to the first position. Please refer toFigure 7 and Figure 8 , the first connecting rod 213 continues to slide downward along the first slide 2111, and the second connecting rod 214 moves from the closed slide 2112b to the downward slide 2112a. At this time, the second connecting rod 214 drives the furnace door 22 to move downward in the Z-axis direction to avoid the discharge port 12 until the furnace door 22 is offset from the discharge port 12 in the Z-axis direction. At this time, the furnace door 22 moves from the first position to the second position.

[0092] When closing the furnace door 22, see Figure 7 and Figure 8 The driving member 212 drives the first connecting rod 213 to move upward along the first slide 2111, and the first connecting rod 213 pulls the corresponding two second connecting rods 214 to move. The end of the second connecting rod 214 connected to the downward slide 2112a first rises along the downward slide 2112a, and then moves to the closed slide 2112b. Figure 5 and Figure 6 At this time, the furnace door 22 corresponds to the discharge port 12 in the X-axis direction, the furnace door 22 moves from the second position to the first position, the first connecting rod 213 continues to slide upward along the first slide 2111, and the second connecting rod 214 drives the furnace door 22 to move toward the discharge port 12 in the X-axis direction until the furnace door 22 covers the discharge port 12 and completes the closure.

[0093] The operation process of the heating furnace 100 provided by the present application to drive the loading mechanism 30 to move when the furnace door 22 is opened or closed is roughly as follows:

[0094] When the closing mechanism 20 opens the oven door 22, see Figures 5 to 8 The rack 23 on the furnace door 22 is meshed with the gear 312. When the furnace door 22 moves, the gear 312 is driven to rotate through the rack 23. When the gear 312 rotates, it drives the traction rod 313 to move. The traction rod 313 pulls the driving part 3113c of the second connecting rod 3113a to move, thereby making the two second connecting rods 3113a rotate close to each other. The two second connecting rods 3113a drive the cross rods 3112a of the multiple cross units 3112 to move, thereby making the cross telescopic arm 311 extend toward the discharge port 12 to drive the loading plate 32 to move out of the heating chamber 11 from the discharge port 12.

[0095] When the closing mechanism 20 closes the furnace door 22, the rack 23 on the furnace door 22 meshes with the gear 312. When the furnace door 22 moves, the gear 312 is driven by the rack 23 to rotate in the opposite direction. The gear 312 drives the traction rod 313 to move. The traction rod 313 drives the two second connecting rods 3113a to rotate away from each other, thereby moving the cross rods 3112a of the multiple cross units 3112, and retracting the cross telescopic arms 311 into the heating chamber 11.

[0096] The heating furnace 100 provided by the embodiment of the present application can heat materials through the heating chamber 11 in the furnace body 10. The closing mechanism 20 can automatically open or close the furnace door 22. The driving component 21 of the closing mechanism 20 can drive the furnace door 22 to move from the feeding port 12 to the first position and drive the furnace door 22 to move from the first position to the second position to open the furnace door 22. When the furnace door 22 moves from the first position to the second position, the rack 23 on the furnace door 22 meshes with the gear 312 of the material loading mechanism 30, thereby causing the gear 312 to rotate. The gear 312 drives the telescopic component 31 to move, so as to move the material loading plate 32 out of the heating chamber 11 when the furnace door 22 is opened. When the driving component 21 drives the furnace door 22 to move from the second position to the first position, the rack 23 meshes with the gear 312, the gear 312 drives the telescopic component 31 to move, the telescopic component 31 drives the material loading plate 32 to move into the heating chamber 11, and the driving component 21 then drives the furnace door 22 to move from the first position to the feeding port 12, thereby closing the furnace door 22. The above-mentioned heating furnace 100 can drive the telescopic component 31 to extend the material loading plate 32 out of the heating chamber 11 when the furnace door 22 is opened, and drive the telescopic component 31 to retract the material loading plate 32 into the heating chamber 11 when the furnace door 22 is closed, with high working efficiency and high safety.

[0097] The working process of the heating furnace 100 provided by the embodiment of the present application is generally as follows:

[0098] When opening the furnace door 22, please refer to Figure 5 and Figure 6 , the driving member 212 drives the first connecting rod 213 to slide downward along the first slideway 2111. The first connecting rod 213 pulls the corresponding two second connecting rods 214 to move. One end of the second connecting rod 214 connected to the closing slideway 2112b first moves away from the feeding port 12 along the closing slideway 2112b. The second connecting rod 214 drives the furnace door 22 to move away from the feeding port 12 in the X-axis direction until the second connecting rod 214 moves to the downward movement slideway 2112a. Please refer to Figure 6 , at this time, the furnace door 22 moves from the feeding port 12 to the first position, and the rack 23 on the furnace door 22 corresponds to the gear 312 in the Z-axis direction. Please refer to Figure 7, the first connecting rod 213 continues to slide downward along the first slideway 2111, the second connecting rod 214 moves along the downward moving slideway 2112a, and the second connecting rod 214 drives the furnace door 22 to move downward in the Z-axis direction, so as to move the furnace door 22 from the first position to the second position. After the rack 23 meshes with the gear 312, it drives the gear 312 to rotate. When the gear 312 rotates, it drives the traction rod 313 to move. The traction rod 313 pulls the driving part 3113c of the second connecting rod 3113a to move, so that the two second connecting rods 3113a rotate and approach each other. The two second connecting rods 3113a drive the cross rods 3112a of the plurality of cross units 3112 to move, so that the cross telescopic arm 311 extends towards the discharge port 12, so as to drive the loading plate 32 to move out of the heating chamber 11 from the discharge port 12. Thus, please refer to Figure 8 , while opening the furnace door 22, the telescopic assembly 31 is driven by the furnace door 22 to move the loading plate 32 out of the heating chamber 11, which is convenient for loading and unloading materials.

[0099] When closing the furnace door 22, please refer to Figure 8 , the driving member 212 drives the first connecting rod 213 to move upward along the first slideway 2111, so as to move the furnace door 22 from the second position to the first position. The first connecting rod 213 pulls the corresponding two second connecting rods 214 to move. The end of the second connecting rod 214 connected to the downward moving slideway 2112a first rises along the downward moving slideway 2112a. Please refer to Figure 7 , at this time, the rack 23 can drive the gear 312 to rotate in the reverse direction. The gear 312 drives the traction rod 313 to move. The traction rod 313 drives the two second connecting rods 3113a to rotate and move away from each other, so that the cross rods 3112a of the plurality of cross units 3112 move, so that the cross telescopic arm 311 retracts into the heating chamber 11. Please refer to Figure 6 , the second connecting rod 214 moves to the closing slideway 2112b. At this time, the furnace door 22 corresponds to the discharge port 12 in the X-axis direction. Please refer to Figure 5 , the first connecting rod 213 continues to slide upward along the first slideway 2111, so as to move the furnace door 22 from the first position to cover the discharge port 12. The second connecting rod 214 drives the furnace door 22 to move towards the discharge port 12 in the X-axis direction until the furnace door 22 covers the discharge port 12, and the closing is completed. Thus, while closing the furnace door 22, the telescopic assembly 31 can be driven by the furnace door 22 to move the loading plate 32 into the heating chamber 11, reducing the operation steps and improving the operation efficiency and safety.
