Detailed Embodiment
[0026] For the convenience of those skilled in the art to understand, the following further describes the utility model with reference to the drawings.
[0027] As Figures 1-3 A transformer bushing cutting device shown, including a workbench 1. A lifting cutting table is installed on the workbench 1. A conveying mechanism is arranged on one side of the lifting cutting table. The lifting cutting table includes a lifting frame 4. A material cutting device is installed on the lifting frame 4. A material pressing device is installed on the side of the lifting frame 4 away from the conveying mechanism. The lifting frame 4 controls the lifting of the material cutting device and the material pressing device, and can press the transformer bushing tightly during cutting, avoiding the shaking or lifting of the transformer bushing during cutting, which affects the beauty of the cut surface and the cutting quality;
[0028] The material pressing device of the utility model includes a mounting block 13. The mounting block 13 is fixed on the lifting frame 4. A through hole is provided on the mounting block 13. A connecting rod 18 is slidably installed on the through hole. A pressing plate 12 is installed at the lower end of the connecting rod 18. A spring 15 is sleeved on the connecting rod 18. One end of the spring 15 is fixed on the mounting block 13, and the other end of the spring 15 is fixed on the pressing plate 12.
[0029] Specifically, a retaining piece 3 is installed at the upper end of the connecting rod 18. The retaining piece 3 is located above the mounting block 13. The pressing plate 12 and the retaining piece 3 jointly limit the up and down movement of the connecting rod 18 to prevent the connecting rod 18 from slipping out of the through hole.
[0030] Specifically, when cutting the transformer bushing, the lifting frame 4 drives the cutting device and the material pressing device to descend together. When the pressing plate 12 abuts against the transformer bushing, it will no longer move downward. In order to completely cut off the transformer bushing, the lifting frame 4 will continue to move downward.
[0031] At this time, the connecting rod 18 slides upward relative to the mounting block 13 and compresses the spring 15. The reaction force generated by the spring 15 will gradually press the pressing plate 12 against the transformer bushing. The material connecting the two sections at the cutting position gradually decreases, and the probability of deformation due to the downward pressure of the cutting device also increases. At this time, the reaction force generated by the spring 15 is also the largest, which can better prevent the transformer bushing from tilting or shifting, greatly reducing the deformation at the cutting position and improving the end cutting quality of the transformer bushing.
[0032] The cutting device of the present utility model includes a second motor and a cutting blade 16. The second motor is fixed on the lifting frame 4, and the cutting blade 16 is installed at the rotating end of the second motor. A plurality of mounting holes 14 are provided on one side of the lifting frame 4 away from the conveying mechanism. The plurality of mounting holes 14 are arranged equidistantly along the width direction of the workbench 1. The mounting block 13 is fixed on the lifting frame 4 by cooperating with the mounting holes 14 through bolts. The position of the pressing plate 12 can be adjusted by changing the fixing position of the mounting block 13, so that the pressing plate 12 can press directly above the transformer bushings with different diameters to ensure the pressing effect.
[0033] Specifically, the lower end surface of the pressing plate 12 is an arc surface 17, and a rubber layer is pasted on the arc surface 17 to increase the friction force of the contact surface with the transformer bushing, avoiding the movement of the transformer bushing along the length direction of the pressing plate 12 during pressing and affecting the cutting quality.
[0034] A waste material groove 11 is provided on the workbench 1 of the present utility model below the lifting frame 4. The length of the waste material groove 11 is greater than the diameter of the cutting blade 16. During cutting, the cut debris and powder can fall from the waste material groove 11. The area below the cutting blade 16 is in a hollow state, and the cutting blade 16 can pass through the waste material groove 11 to completely cut off the transformer bushing, and the workbench 1 will not interfere with the downward movement of the cut piece.
[0035] Specifically, the conveying mechanism includes a conveyor belt 21 for transporting the transformer bushing towards the limiting plate 2. The conveyor belt 21 is located on the side of the lifting frame 4 away from the limiting plate 2. A plurality of limiting rollers 5 arranged along the length direction of the workbench 1 are installed on one side of the conveyor belt 21, and at least two flat push cylinders 8 are installed on the other side of the conveyor belt 21. One end of the flat push cylinder 8 is fixed on the workbench 1, and the other end of the flat push cylinder 8 is connected to a push plate 7 parallel to the length direction of the conveyor belt 21.
[0036] Specifically, the upper end surface of the conveyor belt 21 is flush with the upper end surface of the workbench 1. When the flat push cylinder 8 extends to push the push plate 7 towards the limiting roller 5, the upper end surface of the conveyor belt 21 will not interfere with the movement of the push plate 7, and the push plate 7 can smoothly move above the conveyor belt 21.
[0037] On one side of the push plate 7 of the present utility model facing the limiting roller 5, a number of universal balls 10 are installed. The other side of the push plate 7 is connected to the flat push cylinder 8. Both the push plate 7 and the limiting roller 5 play a role in guiding and limiting the displacement of the transformer tube sleeve, and can also limit the movement of the transformer tube sleeve along the width direction of the workbench 1 during cutting, improving the stability and safety of cutting.
[0038] Specifically, the rotatable limiting roller 5 and the universal balls 10 can reduce the friction with the transformer tube sleeve, enabling the conveyor belt 21 to smoothly drive the transformer tube sleeve to move.
[0039] Specifically, place the transformer tube sleeve on the conveyor belt 21. The flat push cylinder 8 extends to move the push plate 7 towards the limiting roller 5. The push plate 7 pushes the transformer tube sleeve until it abuts against the limiting roller 5. At this time, the conveyor belt 21 starts to convey the transformer tube sleeve towards the lifting cutting table, realizing the feeding and transportation of the transformer tube sleeve.
[0040] Between two adjacent limiting rollers 5 of the present utility model, a lifting pressure plate 6 is installed. The lifting pressure plate 6 includes a lifting cylinder 20 and a cross plate 19. One end of the lifting cylinder 20 is fixed on the workbench 1, and the other end of the lifting cylinder 20 is connected to the cross plate 19. During cutting, the lifting cylinder 20 descends, and the cross plate 19 presses against the transformer tube sleeve, enabling the transformer tube sleeve on the side of the cutting blade 16 away from the pressure device to also be fixed, further avoiding the displacement and upward warping of the transformer tube sleeve, improving the flatness at the cut, and enhancing the aesthetics.
[0041] On the push plate 7 of the present utility model, vertical grooves 9 corresponding to the lifting pressure plates 6 one by one are provided. The width of the vertical grooves 9 is greater than the width of the cross plate 19. The descending height of the cross plate 19 can vary with the diameter of the transformer tube sleeve. When the diameter of the transformer tube sleeve to be cut is smaller than the height of the push plate 7, the cross plate 19 can pass through the vertical groove 9 during descent to press the transformer tube sleeve tightly, and the push plate 7 will not interfere with the descent of the cross plate 19.
[0042] Specifically, a limiting plate 2 is installed on one side of the lifting cutting table away from the conveying mechanism. The limiting plate 2 is detachably installed on the functional workbench 1, and the fixed position can be appropriately adjusted along the length direction of the workbench 1. During cutting, only by abutting the end of the transformer tube sleeve against the limiting plate 2 can it be ensured that the length of each cut transformer tube sleeve is consistent.
[0043] It should be understood that the use of these embodiments is only for illustrating the present utility model rather than intending to limit the protection scope of the present utility model. In addition, it should also be understood that after reading the technical content of the present utility model, those skilled in the art can make various changes, modifications and / or variations to the present utility model, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
