Description

Technical Field

[0001] This utility model relates to the field of flying shear technology, and in particular to a measuring device for a swing-type flying shear used for shearing steel plates. Background Technology

[0002] The flying shear machine uses two rotating mechanisms to synchronously drive two shearing blades to rotate in opposite directions. This allows the shearing blades to remain relatively stationary as they move forward with the steel plate during the shearing process, thus avoiding affecting the steel plate's conveying efficiency and shearing effect.

[0003] However, in existing devices, the blades of the shearing machine gradually wear down after prolonged use, leading to a decrease in shearing efficiency. Therefore, the shearing blade needs to be replaced promptly. However, in existing devices, the shearing blade and connecting parts are fixed together, requiring the connecting parts to be replaced as well, resulting in waste. Therefore, this invention provides a oscillating flying shear measuring device for steel plate shearing to solve the problems mentioned in the background art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a measuring device for a swing-type flying shear machine used for steel plate shearing, aiming to improve the problem in the prior art where the shearing blade and the connecting part are fixed together, and the connecting part needs to be replaced together when the shearing blade is replaced, resulting in waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a measuring device for a swing-type flying shear machine used for steel plate shearing, comprising a mounting frame, two motors fixedly mounted on the right side of the mounting frame, a turntable fixedly connected to the output end of each motor, a connecting shaft rotatably connected inside the turntable, a rotating frame fixedly connected to the lower part of the connecting shaft, a rotating shaft fixedly connected to the lower part of the upper rotating frame, a connecting frame rotatably connected to the lower part of the rotating shaft, an upper shearing blade disposed on the lower side of the connecting frame 1, a lifting rod fixedly connected to the outside of the connecting frame 1, a connecting plate fixedly connected to the lower side of the mounting frame, a rotating platform disposed on the upper part of the connecting plate, a rotating frame fixedly connected to the lower part of the connecting plate, fixed seats fixedly connected to both sides of the upper part of the rotating platform, the lifting rod disposed inside the fixed seats, a connecting frame 2 fixedly connected to the inner side of the fixed seats, a lower shearing blade fixedly mounted on the upper part of the connecting frame 2, and an installation assembly disposed on the lower side of the connecting frame 1 for installing the upper shearing blade.

[0006] Furthermore, the installation assembly includes a connector, which is fixedly connected to the lower part of the connecting frame. Mounting plates are fixedly connected to both sides of the lower part of the connector. A locking rod is fixedly connected to the lower part of the mounting plate. A limiting plate is fixedly connected to the outer side of the upper shearing blade. A locking hole is provided inside the limiting plate. A fastening nut is threaded to the lower side of the locking rod.

[0007] Furthermore, a second motor is fixedly installed on the upper side of the connecting plate, and the output end of the second motor is fixedly connected to the lower side of the rotary table.

[0008] Furthermore, the lever is slidably connected inside the locking hole.

[0009] Furthermore, a limiting block is fixedly connected to the lower part of the connecting frame one, and a limiting groove is opened inside the upper shearing blade, with the limiting block slidably connected inside the limiting groove.

[0010] Furthermore, the rotary table is rotatably connected to the inside of the mounting frame.

[0011] Furthermore, the lifting rod is slidably connected inside the fixed base.

[0012] Furthermore, a controller is fixedly mounted on the right side of the mounting bracket, and the controller is electrically connected to motor one and motor two.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the steel sheet is fed into the mounting frame by a conveyor belt. After the motor is started, its output end drives the turntable to rotate. The turntable then drives the connecting shaft to rotate. The rotation of the connecting shaft causes the rotating frame to rotate continuously. The rotating frame drives the connecting frame and the upper shearing blade to rotate eccentrically. The rotating frames on the upper and lower sides synchronously drive the upper and lower shearing blades to move up and down reciprocally. When the two shearing blades approach each other, they cut the steel plate together, completing the shearing work.

[0015] 2. In this utility model, when it is necessary to disassemble the upper shearing blade, first turn the fastening nut to disengage it from the locking rod, thereby releasing the limiting plate. Then pull the upper shearing blade to move the limiting plate and disengage it from the locking rod, thus completing the disassembly of the upper shearing blade. When installing a new shearing blade, align the locking hole of the new blade with the locking rod, and then turn the fastening nut to fix it, ensuring that the blade is firmly installed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a oscillating flying shear measuring device for steel plate shearing, comprising a mounting frame 1, with turntables 4 rotatably connected to both sides inside the mounting frame 1. Two motors 3 are fixedly mounted on the right side of the mounting frame 1, and the output ends of the motors 3 are fixedly connected to the right turntable 4. A connecting shaft 6 is rotatably connected inside the turntable 4, and a rotating frame 21 is fixedly connected to the lower part of the connecting shaft 6. A rotating shaft 7 is fixedly connected to the lower part of the upper rotating frame 21, and a connecting frame 8 is rotatably connected to the lower part of the rotating shaft 7. An upper shearing blade 9 is provided on the lower side of the connecting frame 8. A lifting rod 12 is fixedly connected to the outside of the mounting frame 1. A connecting plate 15 is fixedly connected to the lower inside of the mounting frame 1. A rotating platform 16 is provided on the upper part of the connecting plate 15. A rotating frame 21 is fixedly connected to the lower part of the connecting plate 15. Fixed seats 11 are fixedly connected to both sides of the upper part of the rotating platform 16. The lifting rod 12 is located inside the fixed seat 11. A second mounting frame 18 is fixedly connected to the inner side of the fixed seat 11. A lower shearing blade 19 is fixedly installed on the upper part of the second mounting frame 18. An installation assembly is provided on the lower side of the first mounting frame 8. The installation assembly is used to install the upper shearing blade 9.

[0024] The steel sheet is conveyed into the mounting frame 1 by a conveyor belt. The motor 3 is started, and the output of the motor 3 drives the turntable 4 to rotate. The turntable 4 drives the connecting shaft 6 to rotate, and the connecting shaft 6 drives the rotating frame 21 to rotate continuously. The rotating frame 21 drives the connecting frame 8 and the upper shearing blade 9 to rotate eccentrically, so that the upper and lower rotating frames 21 drive the upper shearing blade 9 and the lower shearing blade 19 to move up and down repeatedly. At the same time, the lifting rod 12 extends and retracts inside the fixed seat 11. When the two upper shearing blades 9 and the lower shearing blade 19 approach each other, the upper shearing blade 9 and the lower shearing blade 19 together cut the steel plate, completing the shearing.

[0025] Reference Figure 1 , Figure 2 and Figure 4 The installation assembly includes a connector 2, which is fixedly connected to the lower part of the connecting frame 8. Mounting plates 22 are fixedly connected to both sides of the lower part of the connector 2. A locking rod 24 is fixedly connected to the lower part of the mounting plate 22. A limiting plate 23 is fixedly connected to the outer side of the upper shearing blade 9. A locking hole 5 is opened inside the limiting plate 23. A fastening nut 10 is threadedly connected to the lower side of the locking rod 24.

[0026] When it is necessary to disassemble the upper shear blade 9, rotate the fastening nut 10 to disengage it from the clamping rod 24, thereby releasing the limit plate 23 from the fastening nut 10. Pull the upper shear blade 9, and the upper shear blade 9 will move the limit plate 23, causing the limit plate 23 to disengage from the clamping rod 24, thus completing the disassembly of the upper shear blade 9. When installing, align the clamping hole 5 of the new upper shear blade 9 mounting plate 22 with the clamping rod 24, and then rotate the fastening nut 10 to fix it.

[0027] Reference Figure 1 , Figure 3 and Figure 4 A second motor 17 is fixedly installed on the upper side of the connecting plate 15. The output end of the second motor 17 is fixedly connected to the lower side of the rotary table 16. The locking rod 24 is slidably connected to the inside of the locking hole 5. The lower part of the connecting frame 1 8 is fixedly connected to the limiting block 13. The upper shearing blade 9 has a limiting groove 14 inside. The limiting block 13 is slidably connected to the inside of the limiting groove 14. The rotary table 16 is rotatably connected to the inner side of the mounting frame 1. The lifting rod 12 is slidably connected to the inside of the fixed base 11. A controller 20 is fixedly installed on the right side of the mounting frame 1. The controller 20 is electrically connected to the first motor 3 and the second motor 17.

[0028] By starting motor 17, motor 17 drives the rotary table 16 to rotate. The rotary table 16 drives the fixed base 11 to adjust the horizontal angle. The upper shearing blade 9 can be installed and fixed by sliding the locking rod 24 inside the locking hole 5. The upper shearing blade 9 can be limited and fixed by sliding the limiting block 13 inside the limiting groove 14. By rotating the rotary table 16 inside the mounting frame 1, the cutting angle of the steel plate can be adjusted with high precision in a timely manner. By sliding the lifting rod 12 inside the fixed base 11, the lower shearing blade 19 can be driven to slide up and down. The controller 20 is electrically connected to motor 3 and motor 17, and can control the start and stop of motor 3 and motor 17.

[0029] Working Principle: When using this device, the steel sheet is conveyed to the mounting frame 1 via a conveyor belt. The controller 20 starts the motor 3, which drives the turntable 4 to rotate. The turntable 4 drives the connecting shaft 6 to rotate, which in turn drives the rotating frame 21 to rotate continuously. The rotating frame 21 drives the connecting frame 8 and the upper shearing blade 9 to rotate eccentrically, causing the upper and lower shearing blades 9 and 19 to move up and down repeatedly. Simultaneously, the lifting rod 12 extends and retracts within the fixed base 11. When the two upper and lower shearing blades 9 and 19 approach each other, they together cut the steel sheet. This process is controlled by the controller. The device 20 starts the second motor 17, which drives the rotary table 16 to rotate. The rotary table 16 drives the fixed seat 11 to adjust the angle in the horizontal direction, so that after each cutting operation, the shearing blade drives the upper shearing blade 9 and the lower shearing blade 19 to complete a cutting angle adjustment operation. This allows the cutting angle of the steel plate to be adjusted with high precision in a timely manner. During disassembly, the fastening nut 10 is rotated to disengage from the clamping rod 24, releasing the limit plate 23. The upper shearing blade 9 is then pulled, causing the limit plate 23 to move and disengage from the clamping rod 24, thus completing the disassembly of the upper shearing blade 9.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
