Description

Technical Field

[0001] The invention belongs to the technical field of die forging hydraulic presses, and in particular relates to a die forging hydraulic press. Background Art

[0002] The die forging hydraulic press generates huge pressure through the hydraulic system, pushing the movable crossbeam downward, closing the mold installed on the movable crossbeam and the workbench, and applying pressure to the metal billet placed in the mold cavity to cause it to undergo plastic deformation, thereby obtaining forgings of the desired shape and size. For the casting process, the mold design and manufacturing of cylindrical castings is relatively easy. The cylindrical mold structure is relatively simple and the processing difficulty is relatively low, which can reduce the manufacturing cost and production cycle of the mold, and is therefore widely used.

[0003] When the existing die forging hydraulic press is in use, the die will produce mechanical fatigue when it is subjected to the huge pressure and impact force of the metal billet. Long-term mechanical fatigue will cause tiny cracks in the inner wall of the die, and it is difficult for the operator to know the changes in the inner wall of the die in time. When the die with cracks on the inner wall continues to be used, these micro cracks will gradually expand under pressure and impact, eventually causing the die to break, resulting in serious production accidents.

[0042] A buzzer 56 is fixedly connected to the right side wall of the base 1, and the ultrasonic probe 18 is electrically connected to the buzzer 56 through the PLC controller 7. When a large crack is detected on the inner wall of the mold 8, the operator can be automatically reminded to replace the mold 8 to avoid continuing to use the mold 8 with a cracked inner wall, which will cause the mold 8 to break and cause serious production accidents.

[0043] The operating principle of the present invention is now described as follows: when the die forging hydraulic press is idle after work at night, the operator can transmit an electrical signal to the PLC controller 7 through the console 6. After receiving the electrical signal, the PLC controller 7 first controls the drive motor 10 on the left to work, and the drive motor 10 on the left drives the first threaded rod 92 on the left to rotate, and drives the first threaded barrel 11 on the left to move through the thread matching, and the first threaded barrel 11 on the left drives the ultrasonic detection component 16 and the vertical electric push rod 30 to move forward to a suitable position through the translation plate 12 and the bending plate 13, so that The linear motor 161 is located directly above the mold 8. The inner cavity of the mold 8 is a circular structure. The center of the mold 8 and the center of the linear motor 161 are on the same vertical line. In the unstarted state, the vertical electric push rod 30 is in the initial position, which makes the friction disk 31 close to but not in contact with the lower side wall of the turntable 25. When the equipment is started, the vertical electric push rod 30 moves, driving the friction disk 31 to contact the lower side wall of the turntable 25. At this time, the ultrasonic probe 18 and the positioning plate 27 are in the same direction. In the process of moving forward, the vertical electric push rod 30 will drive the positioning assembly 19 to move forward to the top of the mold 8.

[0044] Then the PLC controller 7 controls the linear motor 161 to work, so that the linear motor 161 drives the ultrasonic probe 18 to move downward to the set position through the support frame 162, so that the ultrasonic probe 18 is located in the mold 8. Then the PLC controller 7 controls the angle motor 15 on the left to work, and controls the linear motor 161 to work at the same time. The angle motor 15 drives the left rotating column 14 to rotate through the bevel gear transmission assembly. The left rotating column 14 will drive the positioning plate 27 to rotate together through the friction disk 31 and the rotating disk 25. The lower end of the left rotating column 14 will drive the linear motor 161 to rotate together. After the linear motor 161 rotates one circle, the linear motor 161 will drive the ultrasonic probe 18 to move downward to the set position, and use the ultrasonic probe 18 to detect the inner wall of the mold 8. When the ultrasonic probe 18 detects that the inner wall of the mold 8 has a large crack that is difficult to repair, the buzzer 56 will be controlled by the PLC controller 7 to work to remind the operator to replace the mold 8.

[0045] For example, when the ultrasonic probe 18 detects a transverse crack on the inner wall of the mold 8 (when the ultrasonic wave emitted by the ultrasonic probe 18 encounters a transverse crack, the transverse crack is parallel to the propagation direction of the ultrasonic wave, the reflection of the ultrasonic wave at the crack is relatively weak, the intensity of the reflected wave is small, and the time delay is long. When the reflected wave signal is weak and the wave crest is relatively gentle, there may be a transverse crack; when the ultrasonic wave emitted by the ultrasonic probe 18 encounters a vertical crack, the intensity of the reflected wave is usually large, and the time delay of the reflected wave is short. This is because the vertical crack is perpendicular to the propagation direction of the ultrasonic wave. The ultrasonic wave is reflected more strongly at the crack. For example, during the detection process, if the received reflected wave signal is very strong and the wave crest is sharp, then there is a vertical crack). The ultrasonic probe 18 will control the small electric push rod 40 of the corresponding height to work according to the descending distance of the linear motor 161, so that the small electric push rod 40 drives the limit plate 57 to move, so that the corresponding limit plate 57 moves to the moving path of the limit block 41, and then the PLC controller 7 controls the angle motor 15 on the left to drive the ultrasonic probe 18 to move to the rightmost end of the transverse crack, and then controls the angle on the left The motor 15 works, and the angle motor 15 drives the ultrasonic probe 18 to move to the leftmost side of the transverse crack. When the PLC controller 7 controls the angle motor 15 to work, it also controls the air pump 49 and the upper magnetic control valve 48 to work. The air pump 49 works at a low power. The air pump 49 slowly transports the gas to the upper distance box 421 through the transverse pipe 50 and the U-shaped pipe 47, so that the air pressure in the space on the left side of the upper piston block 422 increases, so that the piston block 422 drives the conductive frame 43 to move to the right. The right side wall of the distance box 421 is provided with an exhaust port. When the ultrasonic probe 1 After 8 moves to the leftmost side of the transverse crack, the PLC controller 7 will control the air pump 49 to stop working, and then control the vertical electric push rod 30 to drive the friction disk 31 to move downward, and control the linear motor 161 to drive the ultrasonic probe 18 to move upward out of the mold 8, and then the PLC controller 7 will control the drive assembly 9 to drive the ultrasonic probe 18 to move forward, and then the PLC controller 7 controls the right bending plate 13 to move through the drive assembly 9, so that the repair box 321 moves to the top of the mold 8, and the side wall of the guide block 21 is connected with a rubber friction block, which will stay in the guide cylinder 20;

[0046] Then the PLC controller 7 controls the angle motor 15 on the right to work, and the angle motor 15 controls the rotation of the rotating column 14 on the right through the bevel gear assembly (the bevel gear assembly is small in size, while the bevel gear ring is large in size, and the angle motor 15 is a reduction motor, so that the rotating column 14 can be controlled to rotate slowly), and the rotating column 14 drives the positioning block 29 to rotate through the push rod 28. When the positioning block 29 contacts the positioning plate 27, since the positioning block 29 is electrically connected to the external power supply, and the positioning plate 27 is electrically connected to the PLC controller 7, when the positioning block 29 contacts the positioning plate 27, an electrical signal will be transmitted to the PLC controller 7. After receiving the electrical signal, the PLC controller 7 will control the angle motor 15 to stop working immediately, so that the welding head 38 rotates to the top of the left end of the transverse crack (the ultrasonic probe 18 rotates to the transverse After the leftmost part of the crack is reached, the positioning plate 27 will be driven to rotate to the leftmost part), and then the PLC controller 7 controls the working motor 33 to work, and the working motor 33 drives the second threaded rod 34 to rotate, and drives the second threaded barrel 35 to move downward through the threaded cooperation, and the second threaded barrel 35 drives the welding head 38 and the grinding assembly 58 to move downward together through the placement plates on both sides, until the limit block 41 on the rear side of the second threaded barrel 35 contacts the previously moved limit plate 57, the limit block 41 is electrically connected to the external power supply, and the limit plate 57 is electrically connected to the PLC controller 7. When the limit block 41 contacts the limit plate 57, an electrical signal will be transmitted to the PLC controller 7. After receiving the electrical signal, the PLC controller 7 will control the first micro electric push rod 37 to drive the welding head 38 to move toward the left end of the weld;

[0047] At the same time, the PLC controller 7 controls the upper control valve 46 to open, so that the gas inside the upper fixed-distance box 421 is discharged through the fine hole tube 45 (the exhaust time of the fixed-distance box 421 through the fine hole tube 45 is the same as the intake time). The piston block 422 inside the upper fixed-distance box 421 will gradually move to the left under the action of the spring force. When the PLC controller 7 controls the upper control valve 46 to open, the PLC controller 7 conductive frame 43 is energized, the conductive frame 43 is electrically connected to the external power supply, the conductive frame 43 is in contact with the upper conductive plate 44, and the conductive plate 44 is electrically connected to the PLC controller 7. After the electric frame 43 and the conductive plate 44 are in continuous contact, an electric signal will be continuously transmitted to the PLC controller 7. After receiving the electric signal, the PLC controller 7 will control the welding head 38 to work and weld the weld. At the same time, the PLC controller 7 controls the angle motor 15 on the right to work. The angle motor 15 controls the rotation of the rotating column 14 on the right through the bevel gear transmission assembly, so that the welding head 38 rotates from the left side to the right along the transverse crack. When the gas inside the upper distance box 421 is completely discharged, the upper conductive frame 43 and the conductive plate 44 will separate, so that the welding head 38 stops The PLC controller 7 will then control the right angle motor 15 to operate, so that the angle motor 15 controls the repair box 321 to rotate 180 degrees, so that the positions of the welding head 38 and the grinding head 55 are swapped, and then the PLC controller 7 controls the second micro electric push rod 53 to operate, so that the second micro electric push rod 53 drives the grinding head 55 and the welding part to maintain a certain pressure, and then the PLC controller 7 controls the grinding head 55 to rotate along the right end of the transverse crack to the left end, and controls the grinding motor 54 to operate, so as to grind the welding part (the time for the grinding head 55 to rotate along the right end of the transverse crack to the left end will be determined according to the rotation time of the grinding head 55). According to the working time of the welding head 38, the PLC controller 7 will record the working time of the welding head 38 through the timing module). When the grinding head 55 moves to the leftmost end of the transverse crack, the PLC controller 7 will control the second micro electric push rod 53 to drive the grinding head 55 to continue to move, and then repeat the grinding work to clean the solder layer by layer until the second micro electric push rod 53 drives the grinding head 55 to move to the set distance (the rotation radius of the grinding head 55 is the same as the inner wall radius of the mold 8), and the solder can be polished flat. Referring to the above principle, the vertical cracks can be polished;

[0048] Then the PLC controller 7 controls the grinding head 55 and other components to detach from the mold 8, and drives the repair component 32 to move backward to the initial position through the driving component 9, and controls the ultrasonic detection component 16 to drive the positioning component 19 to move backward to the initial position for placement. After the equipment is finished working, the operator can adjust the direction of the positioning block 29 and the positioning plate 27 through the console 6 to facilitate the next maintenance work.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
