Description

[0001] The present invention belongs to the technical field of heat treatment transfer logistics, and in particular relates to an automatic transfer device and method for heat treatment of extra-long rods. Background Art

[0002] At present, the length of rods at home and abroad is generally less than 12m. There is no special heat treatment transfer logistics device for the heat treatment of super-long rods with a length of about 12 to 18m. Generally, the logistics transfer of rods is mainly realized by manually controlling the driving. This operation method is difficult to operate, the positioning is not accurate, the operation time is long, and the quality of workers is high. Especially in the field of heat treatment, it is difficult to accurately control the time of heat treatment out of the furnace and taking out the parts, which affects the heat treatment effect of the rods. If the automated transfer logistics of super-long rods can be realized, the dependence on workers can be reduced to a certain extent. At the same time, because the time of taking out of the furnace and entering the liquid can be effectively controlled, the heat treatment effect of the rods can be greatly improved. Therefore, we propose an automated transfer equipment and method for heat treatment of super-long rods. Summary of the invention

[0058] An automated transfer method for heat-treating an extra-long rod, using the above-mentioned automated transfer equipment for heat-treating an extra-long rod, comprises the following steps:

[0059] During operation, the fork device 610 is moved on the X, Y and Z axes through the Y-axis electric walking mechanism 650, the X-axis electric walking mechanism 640 and the Z-axis hydraulic lifting mechanism. First, the fork device 610 reaches the loading station 1 and picks up the extra-long rod 7, moves the extra-long rod 7 to the heat treatment furnace 2, places it there and then exits. The extra-long rod 7 is heat treated in the heat treatment furnace 2. After the time is up, the extra-long rod 7 is picked up by the fork device 610 and moved to the heat treatment water tank 3. After the treatment is completed, the extra-long rod 7 is moved to the unloading station 4.

[0060] The working principle of the present invention is:

[0061] 1. When the automatic transfer logistics device 6 receives a command from the PLC control program during operation, the driving reduction motor 2 652 on the Y-axis electric walking mechanism 650 rotates, driving the driving wheel 2 651 to rotate, thereby driving the entire Y-axis electric walking mechanism 650 to move to the loading station 1.

[0062] 2. The encoder on the driving reduction motor 2 652 calculates that the automatic transfer logistics device 6 is in place, and at the same time the proximity switch sensor senses that the ground position is correct. The two signals are fed back to the PLC control system, and the system issues a command for the Y-axis electric walking mechanism 650 to stop.

[0063] 3. At the same time, the Z-axis hydraulic lifting mechanism is commanded to drive the load-bearing beam 624 on the guide wheel device 620 to move up and down. The load-bearing beam 624 drives the lifting chain 622 through the load-bearing wheel 623, and drives the lifting chain 622 to drive the fork structure 611 to move up and down to the specified position. During the movement, each group of guide wheels A612 and guide wheels B613 slide in the slide bar 621 and the slide groove 625 respectively to guide in two directions, overcoming the axial force borne by the lifting cylinder 631. The lifting position is determined by the displacement sensor built into the lifting cylinder 631, and the position feedback of each sensor is calculated through the PLC control system to ensure the synchronization of each lifting cylinder 631.

[0064] 4. After the fork structure 611 reaches the specified position, the driving reduction motor 642 on the X-axis electric travel mechanism 640 drives the driving wheel 641 to rotate, thereby driving the entire X-axis electric travel mechanism 640 to move. The encoder on the driving reduction motor 642 calculates that the X-axis electric travel mechanism 640 is in place, and the proximity switch sensor senses that the ground position is in place correctly. The two signals are fed back to the PLC control system, and the system issues a command to the X-axis electric travel mechanism 640 to stop the action, thereby realizing that the X-axis electric travel mechanism 640 drives the fork device 610 to move to the material picking station.

[0065] 5. Repeat the process in step 3, and the Z-axis hydraulic lifting mechanism drives the fork device 610 to lift the extra-long rod 7 to a certain height.

[0066] 6. Repeat the process in step 4. The X-axis electric walking mechanism 640 drives the Z-axis hydraulic lifting mechanism to drive the fork device 610 to retreat to the specified position.

[0067] 7. Repeat the process action of step 1. The Y-axis electric walking mechanism 650 drives the entire automatic transfer logistics device 6 to the heat treatment furnace 2 station and places the extra-long rod 7.

[0068] 8. Then the entire automatic transport logistics device 6 exits. After the rod is heated up, the automatic transport logistics device 6 receives the command and repeats the above steps 3 and 4 to take out the extra-long rod 7, and then performs the step 3 to lower the extra-long rod 7 to the designated position in the heat treatment water tank 3. After the rod is cooled, the step 3 is repeated to lift the extra-long rod 7 to the designated position. Then the steps 1, 4, and 3 are repeated to place the extra-long rod 7 at the unloading station 4 for unloading. After unloading, the next work cycle is performed.
