Hot rolling is a process of heating a metal material to a temperature higher than the recrystallization temperature to roll the metal material into a profile or a plate having a specific shape. The metal material is heated to be above the recrystallization temperature during hot rolling, so that the plasticity of the metal material is higher, the deformation resistance is lower, and the energy consumption of metal deformation is greatly reduced. The hot rolling can reduce the process difficulty of rolling, improve the tissue compactness of the metal material and improve the processing performance of the metal material.
In order to hot-roll a metal material, the metal material is generally heated in a dedicated heating furnace. The gas heating furnace is a heating furnace which uses combustible gas as a heat source, and has the advantages of high heating power and high energy utilization rate. In order to improve the heating efficiency of the copper ingot and the uniformity of the temperature of the copper ingot, the copper ingot is generally transversely fed into a gas heating furnace through a feed inlet by a feed mechanism for heating. Because the weight of copper ingot is usually great, need use fork truck or driving to hoist to feeding mechanism on, and fork truck and driving are relatively poor to the controllability of charging position, are difficult to guarantee the accurate positioning of copper ingot on feeding mechanism. The deviation of the copper ingot position easily causes that the copper ingot collides with the feeding hole when entering the feeding hole of the gas heating furnace, or the two ends of the copper ingot in the gas heating furnace are in different heating areas, so that the copper ingot on the feeding mechanism is required to be subjected to position adjustment.
The existing feeding mechanism of the stepping copper ingot gas heating furnace is generally provided with centering sliding blocks which are synchronously moved to a central line from two sides of the feeding mechanism at two sides of the feeding mechanism, and the copper ingot is pushed to the center of the feeding mechanism from two ends of the copper ingot through the centering sliding blocks, so that the copper ingot is adjusted to a centering state, namely, a state that the center of the copper ingot is positioned on the central line of the width direction of the feeding mechanism. However, when the weight of the copper ingot is large, it is not easy to push the copper ingot to move transversely on the conveying mechanism. Moreover, the feeding mechanism of the step-by-step copper ingot gas heating furnace is usually a step-by-step feeding mechanism, copper ingots on the step-by-step feeding mechanism are usually placed on beam frames arranged at intervals, the resistance of the copper ingots to transverse sliding is increased, and the copper ingots to transverse sliding on the beam frames also easily cause surface scratches of the copper ingots.

Detailed Description
The following describes specific embodiments of the present application in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the application, are not intended to limit the application.
In the present application, unless otherwise stated, the azimuth words such as "up and down" are used to indicate azimuth or positional relationship based on the azimuth or positional relationship of the feeding mechanism of the step copper ingot gas heating furnace of the present application when actually used. The azimuth and position relation indicated by the azimuth words of front and rear are based on the normal conveying direction of the copper ingot when the feeding mechanism of the stepping copper ingot gas heating furnace and the stepping copper ingot gas heating furnace work normally, wherein the previous conveying direction of the copper ingot is the front. The azimuth term "transverse" refers to a direction perpendicular to the direction of conveyance of the copper ingot.
In the description of the present application, it should be noted that, unless explicitly stated and limited otherwise, the terms "disposed" and "connected" should be interpreted broadly, and for example, they may be fixedly connected, detachably connected, or integrally connected; either directly or indirectly via an intermediate medium, or in communication with each other or in interaction with each other. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.
An embodiment of a feeding mechanism of a stepping copper ingot gas heating furnace of the application, as shown in fig. 1-3, comprises a stepping feeding unit 1, a deviation rectifying unit 2 and a centering unit 3, wherein the deviation rectifying unit 2 and the centering unit 3 are arranged on the stepping feeding unit 1 or adjacent parts of the stepping feeding unit 1 and are used for rectifying and centering copper ingots 4 added to the stepping feeding unit 1 through a forklift or a crane.
The step feed unit 1 includes a step beam 11, a step fixed beam 12, and a step drive assembly 13. The walking beams 11 and the walking beams 12 are arranged in a direction parallel to the conveying direction of the copper ingot 4, and the walking beams 11 and the walking beams 12 are arranged at intervals, and normally, the walking beams 11 are arranged between the walking beams 12. The stepping beam 11 is disposed on the stepping driving assembly 13, or is connected to the stepping driving assembly 13, the stepping driving assembly 13 is a driving mechanism capable of generating movement in the up-down direction and overlapping movement in the front-rear direction, and the stepping beam 11 can reciprocate in the up-down direction and the front-rear direction under the driving of the stepping driving assembly 13.
The step fixed beam 12 is fixedly provided on the ground or a specific mounting structure. When the stepping beam 11 descends under the driving of the stepping driving assembly 13, the height of the stepping beam 11 is lower than that of the stepping fixed beam 12, and at this time, the copper ingot 4 is transversely loaded on the stepping feeding unit 1 through a forklift or a travelling crane, and the stepping fixed beam 12 supports the copper ingot 4. The step driving assembly 13 drives the step beam 11 to ascend, and the height of the step beam 11 is gradually higher than that of the step fixed beam 12, so that the copper ingot leaves the step fixed beam 12 and is borne on the step beam 11; the step driving assembly 13 drives the step beam 11 to move backwards to transfer the copper ingot 4 to the next step position, at this time, the step driving assembly 13 drives the step beam 11 to descend, so that the height of the step beam 11 is gradually lower than that of the step beam 12, the copper ingot 4 is born on the step beam 12 again, and the copper ingot 4 is transferred to the next step position on the step beam 12. The step driving assembly 13 drives the step beam 11 to move forward again to return to the initial position, and the copper ingot 4 is ready for the next transfer.
The deviation rectifying unit 2 comprises a deviation rectifying and positioning device 21 and a deviation rectifying and pushing device 22. The deviation correcting and positioning device 21 is arranged on the stepping fixed beam 12, so that the positioning surface of the deviation correcting and positioning device 21 is perpendicular to the conveying direction of the stepping feeding unit. The deviation rectifying and pushing device 22 can be various devices capable of pushing the copper ingot to move, such as a cylinder, a hydraulic cylinder, an electric push rod and the like, the deviation rectifying and pushing device 22 is arranged in front of the deviation rectifying and positioning device 21, and the pushing direction of the deviation rectifying and pushing device 22 is perpendicular to the positioning surface of the deviation rectifying and positioning device 21.
When the copper ingot 4 is loaded on the stepping feeding unit 1, the copper ingot 4 is loaded between the deviation rectifying and positioning device 21 and the deviation rectifying and pushing device 22. Since the loading position of the copper ingot 4 is manually controlled by an operator, it is difficult to ensure that the copper ingot 4 is positioned at an accurate lateral and central position on the stepping fixed beam 12, and the deflection of the copper ingot 4 is unavoidable. After the copper ingot 4 is loaded on the stepping fixed beam 12, the deviation rectifying pushing device 22 is started to push the copper ingot 4 to a position close to the locating surface of the deviation rectifying locating device 21, so that the copper ingot 4 can be conveniently adjusted to be perpendicular to the conveying direction, and the deviation rectifying of the position of the copper ingot 4 is completed. Because the pushing direction of the deviation rectifying pushing device 22 is parallel to the length direction of the stepping fixed beam 12, the copper ingot 4 slides along the length direction of the stepping fixed beam 12 under the pushing of the deviation rectifying pushing device 22, the sliding resistance is small, and the stepping fixed beam 12 usually cannot scratch the copper ingot 4. In the process of conveying the copper ingot 4, the walking beam 11 firstly lifts the height of the copper ingot 4, and the height of the copper ingot 4 can be easily higher than the height of the deviation correcting and positioning device 21 by controlling the height of the deviation correcting and positioning device 21, so that the deviation correcting and positioning device 21 does not obstruct the conveying of the copper ingot 4.
The centering unit 3 comprises centering detection means and a centering adjustment roller assembly 31. The centering detection device can be various devices capable of detecting the centering state of the copper ingot 4, and the centering state of the copper ingot 4 in the centering state can be detected by detecting the positions of the two ends of the copper ingot. Since both ends of the copper ingot 4 are generally symmetrical structures having the same shape, the centering state of the copper ingot 4 can also be detected by detecting the weight of both end portions of the copper ingot 4. The centering detection device can detect whether the copper ingot 4 is in a centering state, and can also detect to which end the copper ingot 4 is offset when the copper ingot 4 is not centered.
The centering roller assembly 31 is a combined structure capable of adjusting the lateral position of the copper ingot 4 through a roller, the centering roller assembly 31 is usually arranged at a stepping position of the copper ingot 4, when the copper ingot 4 is transferred to the stepping position, the copper ingot 4 is positioned on the centering roller assembly 31, and the centering roller assembly 31 controls the roller to rotate according to the detection result of the centering detection device, so that the copper ingot 4 is driven to laterally move to a centering position. Because copper ingot 4 does not contact with other structures outside the roller bearing when transversely moving, the copper ingot 4 can be prevented from being deflected under the action of external force in the moving process, the stability of the copper ingot when moving is ensured, and the copper ingot 4 can be prevented from being scratched and damaged by other objects in the moving process.
In some embodiments of the feeding mechanism of the step copper ingot gas heating furnace of the present application, as shown in fig. 1 and 3, a feeding base 5 is disposed right below the position of a step moving beam 11, and a step driving assembly 13 is disposed in the feeding base 5, so that the step moving beam 11 can be mounted on the step driving assembly 13 without increasing the height of a step fixed beam 12.
The step drive assembly 13 includes a ramp slide rail 131, a lift carriage 132, a lift drive 133, a translation carriage 134, and a translation drive 135. The slope slide rail 131 is a slide rail with a slide rail track and a mounting surface forming a certain angle, the slope slide rail 131 is mounted at the bottom of the feeding base 5, and the slide rail track and the bottom surface of the feeding base 5 form a slope. The lifting rack 132 is mounted on the slope slide rail 131 and can slide along the slide rail of the slope slide rail 131. Specifically, the lifting rack 132 may slide on the slope slide rail 131 through the cooperation of the pulley on the slope slide rail 131, or may slide on the slope slide rail 131 through a slope slide groove adapted to the slide rail track of the slope slide rail 131.
The elevation driving unit 133 may use various devices capable of pushing the elevation stage 132 to move, and generally, the elevation driving unit 133 may use an air cylinder, a hydraulic cylinder, an electric push rod, or the like. Lifting drive device mounting structures are arranged on the lower portion of the lifting rack 132 and the side wall of the feeding base 5, one end of the lifting drive device 133 is hinged with the lifting drive device mounting structure on the side wall of the feeding base 5, and the other end is hinged with the lifting drive device mounting structure on the lifting rack 132. The lifting rack 132 can be driven to slide along the slope slide rail 131 by the extension and contraction of the lifting driving device 133, so that the lifting rack 132 moves to one side of the feeding base 5 and simultaneously lifts in height.
The translation stage 134 is mounted on the elevation stage 132 and is capable of moving back and forth relative to the elevation stage 132. The translation driving device 135 may use various devices capable of pushing the translation stage 134 to move, and in general, the translation driving device 135 may use a cylinder, a hydraulic cylinder, an electric push rod, etc. A translational driving device mounting structure is arranged at the lower part of the translational bench 134, and a translational driving device mounting structure is also arranged at a position on the front side wall of the feeding base 5, wherein the position is close to the position in height, one end of the translational driving device 135 is hinged with the translational driving device mounting structure on the feeding base 5, and the other end of the translational driving device 135 is hinged with the translational driving device mounting structure on the translational bench 134, so that the translational driving device 135 is in an approximately horizontal state. When the translation driving device 135 performs a telescopic motion, the translation stage 134 can be driven to move in the front-rear direction. Meanwhile, when the lifting driving device 133 is extended and contracted, since the lifting rack 132 and the translation rack 134 can generate relative sliding, the translation motion of the lifting rack 132 cannot be transferred to the translation rack 134, and the lifting motion of the lifting rack 132 will be transferred to the translation rack 134, resulting in lifting of the translation rack 134.
The walking beam 11 is fixed to the translation stage 134, and can be lifted and lowered according to the lifting and lowering of the translation stage 134, and translated according to the translation of the translation stage 134. When the translation stage 134 is lifted, although a certain amount of translation is caused in a state where the translation driving device 135 is not operated, the lifting amplitude of the translation stage 134 is not large, when the copper ingot 4 is simultaneously contacted with the walking beam 11 and the stepping fixed beam 12, the translation driving device 135 is in a nearly horizontal state, the translation of the translation stage 134 is very little, and the copper ingot 4 does not slide relative to each other when being transferred between the walking beam 11 and the stepping fixed beam 12.

After the copper ingot 4 is loaded to the copper ingot loading position, the correction pushing device 22 pushes the copper ingot 4 to a position close to the correction limiting block, and correction of the copper ingot 4 is completed. The copper ingot 4 after deviation correction moves to a first stepping position under the drive of the stepping driving assembly 13.
The adjustment beam 122 is a fixed beam for mounting the centering adjustment roller assembly, and the adjustment beam 122 is disposed outside of all the walking beams 11 and is located at a position laterally opposite to the first stepping position of the feeding fixed beam 121.

The distance between the photoelectric detection devices on two sides of the stepping fixed beam 12 can be set according to the detected length of the copper ingot 4, generally, the distance between the photoelectric detection devices on two sides of the stepping fixed beam 12 is equivalent to the length of the copper ingot 4, and the midpoint of the connecting line of the two photoelectric detection devices is located on the transverse central line of the feeding structure. The two photoelectric detection devices may be configured such that, when the copper ingot 4 is in the centered position, the two photoelectric detection devices can detect the end of the copper ingot 4 at the same time or cannot detect the end of the copper ingot 4 at the same time, so that, when one of the two photoelectric detection devices detects the end of the copper ingot 4 and the other does not detect the end of the copper ingot 4, it is possible to determine that the copper ingot 4 is in the non-centered position and to determine the offset direction of the copper ingot 4.
