[0015] A method for conveying materials into and out of an annealing furnace comprises the following steps:

[0016] S1. When in use, the power vehicle is controlled to move to achieve the position movement of the two gantries. During the movement of the gantry positions, the first servo motor is powered on to operate to achieve the rotation adjustment of the gantry relative to the power vehicle, so that the vertical section above the auxiliary ball wheel on the gantry rotates away from the single track;

[0017] S2.

Then, the two first servo motors are powered on to rotate the two gantries relative to the two power cars again.

[0018] S3. Controlling the vertical section above the auxiliary ball wheel on the gantry to rotate close to the single track, thereby achieving synchronous relative rotation and resetting of the two gantries, so that the two ends of the annealing target workpiece can be inserted into the two gantries respectively.

After clamping, the electric lifting rod is controlled to raise the height of the lifting frame. During this process, the annealing target workpiece will rise synchronously with the rise of the two lifting frames. When the annealing target workpiece is raised to a height higher than the single track, the power car is operated to move the annealing target workpiece closer to the carrier plate.

[0020] S5. After the annealing target part is close to a suitable position relative to the carrier plate, the electric lifting rod is operated to further raise the lifting frame until the annealing target part is higher than the carrier plate. The power vehicle continues to move to move the annealing target part directly above the carrier plate. The electric lifting rod then controls the lifting frame to lower the height of the annealing target part so that the annealing target part contacts the carrier plate. The rotating clamping structure is then operated to release the clamping action on the annealing target part.

[0021] S6. The power car then moves in the reverse direction to exit the movable annealing furnace. After the power car completely exits the movable annealing furnace, the movable annealing furnace operates to envelop and cover the annealing target parts, and finally performs an annealing operation on the annealing target parts. After the annealing is completed, the loading and unloading structure operates again to discharge and transport the annealing target parts on the carrying plate.

The outer rotation of the carrier plate 1 is connected to a fixed bracket 29.

[0045] The first servo motor 7, electric lifting rod 10, electric adjustment rod 13, electromagnet 20, electric drive rod 30 and second servo motor 38 in this embodiment are all conventional equipment purchased on the market and well known to those skilled in the art. In the present invention, we only use them and do not improve their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of the instruction manual, and will not be described in detail here.

[0046] In summary, the working principle of the annealing furnace in-and-out material conveying system and method is that before use, the annealing furnace in-and-out material conveying system is first installed and debugged. When it is used after debugging is completed, the power car 4 is controlled to move to realize the position movement of the two gantries 6. The movement principle of the power car 4 is that the first servo motor 7 is powered on to move to realize the rotation drive of the power wheel 36, and the rotation of the power wheel 36 forms a rolling movement relative to the monorail 3, and finally forms the movement of the power car 4 relative to the monorail 3. During the position movement of the gantry 6, the first servo motor 7 is powered on and operated. A driving gear ring 44 and a driven gear ring 45 are respectively installed on the output shaft of the first servo motor 7 and the gantry 6, and the driving gear ring 44 and the driven gear ring 45 are respectively installed on the output shaft of the first servo motor 7 and the gantry 6, and the driving gear ring 44 and the driven gear ring 45 are respectively installed on the output shaft of the first servo motor 7 and the gantry 6. The rings 45 are meshed with each other, so the first servo motor 7 is powered on to realize the rotation adjustment of the gantry 6 relative to the power car 4, so that the vertical section above the auxiliary support ball wheel 8 on the gantry 6 rotates away from the monorail 3. When the power car 4 approaches the suitable area of ​​the annealing target part, the two power cars 4 stop moving relative to the monorail 3, and the two electric lifting rods 10 both work to make the two lifting frames 9 rise relative to the two gantries 6 respectively. Then the two first servo motors 7 are powered on to realize the rotation of the two gantries 6 relative to the two power cars 4 again, and control the vertical section above the auxiliary support ball wheel 8 on the gantry 6 to rotate close to the monorail 3, forming a synchronous relative rotation reset of the two gantries 6, so that the two sides of the annealing target part are The two ends can be inserted relative to the two gantries 6 respectively, and then the two electric lifting rods 10 are controlled to work, so that the two lifting frames 9 are reduced in relative height relative to the annealing target part, until the two ends of the annealing target part respectively enter the corresponding clamping areas of the two rotating clamping structures, and the two rotating clamping structures are controlled to form corresponding clamps on the two ends of the annealing target part respectively. After the clamping is completed, the height of the lifting frame 9 is raised by controlling the electric lifting rod 10. In this process, the annealing target part will rise synchronously with the rise of the two lifting frames 9. When the height of the annealing target part is higher than the single track 3, the power car 4 works to move the annealing target part closer to the carrier plate 1. After reaching a suitable position, the electric lifting rod 10 works to further raise the lifting frame 9 until the annealing target part is higher than the load-bearing plate 1. The power car 4 continues to move to move the annealing target part into the top of the load-bearing plate 1. Then the electric lifting rod 10 works to control the lifting frame 9 to lower the height, so that the annealing target part contacts the load-bearing plate 1. The rotating clamping structure works to release the clamping action on the annealing target part. Then the power car 4 moves in the opposite direction to exit the movable annealing furnace. After the power car 4 completely exits the movable annealing furnace, the movable annealing furnace works to cover and envelop the annealing target part, and finally performs an annealing operation on the annealing target part. After annealing is completed, the loading and unloading structure works again to discharge and convey the annealing target part on the load-bearing plate 1.

[0047] Furthermore, the rotating clamping structure has two clamping modes. When the clamping position of the annealing target part is a cylindrical structure, the four electric adjustment rods 13 can be controlled to work. Under the transmission action of the transmission rod 14 and the arc-shaped hinge seat 15, the four electric adjustment rods 13 respectively drive the two first rotating racks 11 to rotate and the two second rotating racks 12 to rotate. During the rotation of the first rotating rack 11, the bottom end is rotated and extended. During the rotation of the second rotating rack 12, the bottom end is also rotated and extended, and finally the annealing target part is formed to be tightly clamped. When the corresponding clamping position of the annealing target part is a vertical plane, the four electric adjustment rods 13 are operated to make the two first rotating racks 1 1 are respectively received in the two lifting frames 9, and the two second rotating frames 12 are also respectively received in the two lifting frames 9. At this time, the eight electrically connected electrode groups 23 are respectively in contact with the eight power access electrode groups 16, thereby achieving power connection of the eight electromagnets 20. The eight electromagnets 20 all generate electromagnetic fields, and the eight electromagnetic fields act on the eight permanent magnets 22 respectively. The magnetic force of the electromagnetic fields acting on the permanent magnets 22 is controlled to be a repulsive force. Under the action of the repulsive force, the eight sliding guide sliders 19 are respectively pushed out relative to the eight side slide cylinders 18, and finally the sliding frame 17 is pushed. The sliding frame 17 is pushed and drives the contact clamping cap 28 to form a relatively close relationship with the annealing target part. Until the annealing target part is in contact and clamped, in this clamping state, the vertical plane of the matching annealing target part can form a corresponding clamping. After the annealing target part is loaded, the two shifting vehicles 33 move closer to each other, realizing the mutual approach of the two shifting furnaces 34. When the two shifting furnaces 34 are close to each other and in contact with each other, a closed space can be formed relative to the annealing target part. Heating function components are provided in the two shifting furnaces 34, which heat the annealing target part. After the heating is completed, the annealing target part is slowly cooled to realize the annealing operation of the annealing target part. After the annealing is completed, the two shifting vehicles 33 move away from each other, so that the two shifting furnaces 34 are separated from each other and Move away until there is unloading space for the annealing target parts between the two opposing furnaces 34, and the opposing shifting car 33 stops moving. Thereafter, the loading and unloading structure works again to form unloading and conveying of the annealing target parts on the carrier plate 1. During the unloading and conveying process, the lifting frame 9 is raised to the corresponding height of the annealing target parts, and the clamping structure is rotated to form clamping. After the clamping is completed, the lifting frame 9 is raised again to pick up the annealing target parts on the carrier plate 1, and then the power car 4 is controlled to move. When the annealing target parts move to the corresponding position, the height of the lifting frame 9 is lowered. After the annealing target parts form relative contact with the stacking surface and are supported, the clamping structure is rotated to release the clamping of the corresponding annealing target parts.

[0048] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
