[0002] The power fitting is a metal accessory for connecting and combining various devices in a power system, and plays a role of transferring mechanical load, electrical load and protection. The power fitting is mostly made of steel, iron, copper or aluminum, and is various in types. According to the functions and structures, the power fitting can be divided into categories such as suspension clamps, strain clamps, connecting fittings, joint fittings and protection fittings. The power fitting is very important in the power system, and undertakes core tasks such as transferring mechanical load, ensuring electrical connection and providing protection function, and is related to the safe operation of the entire power grid. The power fitting production cutting equipment is a core processing equipment in the front process of the power fitting manufacturing process, and specifically refers to a special equipment for cutting raw materials of the power fitting into blanks or semi-finished products meeting the requirements of subsequent processing through mechanical, thermal and cold cutting principles.

[0003] During cutting, the contact pressure between the cutter and the material causes the cutter to deform or change the cutting path under the action of force, which affects the cutting processing effect of the material.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution:

[0034] A power fitting manufacturing and cutting equipment, comprising:

[0035] The frame 1 has slide rails 4 fixedly installed on both sides of the top of the frame 1. A cylinder 5 is fixedly installed on the top of the frame 1. The cylinders 5 are symmetrically installed along the center of the axis of the frame 1 and are located on both sides of the slide rails 4.

[0036] The top material mechanism 2 is slidingly installed between the slide rails 4, and the output end of the air cylinder 5 is fixedly connected to the outer side of the top material mechanism 2.

[0037] The fixing mechanism 3 is installed on the top of the top material mechanism 2 and is symmetrically installed along the central position of the axis of the top material mechanism 2.

[0038] A groove is formed on one side of the top of the frame body 1, and a protective cover 7 is fixedly installed at the groove on the top of the frame body 1. The outer side of the protective cover 7 is fixedly installed with a motor 6. The output end of the motor 6 penetrates through the protective cover 7 and extends into the interior thereof. The output end of the motor 6 is fixedly connected with a rotating shaft 9 through a shaft coupling. A thread is formed on the end of the rotating shaft 9 away from the motor 6. A fixed disc 13 is fixedly installed on the end of the rotating shaft 9 close to the motor 6. A saw disc 8 is installed on the outer side of the rotating shaft 9. A plurality of studs are uniformly arranged on the side of the fixed disc 13 close to the saw disc 8. The studs penetrate through the saw disc 8 and extend to the other side and fix the saw disc 8 through nuts. When the motor 6 drives the saw disc 8, the motor 6 drives the rotating shaft 9 to rotate in the interior of the protective cover 7. Through the fixed disc 13 fixedly installed on the outer side of the rotating shaft 9, the fixed disc 13 is fixedly connected with the saw disc 8, so that the fixed disc 13 drives the saw disc 8 to rotate at a high speed in the interior of the protective cover 7 when the fixed disc 13 rotates with the rotating shaft 9. In the process of rotation, the bar is cut and cut off through the contact with the bar. At the same time, in the process of cutting, the pads 12 contact with the two sides of the saw disc 8. The pads 12 contact with the saw disc 8 at the position close to the cutting edge on the outer side of the saw disc 8 to limit the deviation of the saw disc 8. The two sides of the inner wall of the protective cover 7 are fixedly installed with inner cover discs 11. A ring groove is formed on the side of the inner cover disc 11 close to the saw disc 8. The pads 12 are rotatably installed in the ring grooves of the inner cover discs 11. The side of the pads 12 close to the saw disc 8 contacts with the outer side of the saw disc 8.

[0039] A screw sleeve 10 is threadedly connected to the end of the rotating shaft 9 away from the motor 6. A ring groove is formed on the end of the screw sleeve 10 close to the saw disc 8. The inner ring pads 14 are fixedly installed in the ring grooves of the screw sleeve 10. When the saw disc 8 is fixed, the screw sleeve 10 cooperates with the fixed disc 13. After the saw disc 8 and the fixed disc 13 are fixed through nuts, the screw sleeve 10 is threadedly connected with the rotating shaft 9, so that the screw sleeve 10 drives the inner ring pads 14 to tightly contact with the saw disc 8 to press the saw disc 8 to the fixed disc 13. The side of the inner ring pads 14 close to the saw disc 8 tightly contacts with the outer side of the saw disc 8. The inner ring pads 14 are made of rubber.

[0040] The second embodiment is based on the first embodiment. Please refer to Figures 6 to 7As shown, the top material mechanism 2 includes two sliders 21, and the bottom of the sliders 21 is slidably adapted to the top of the slide rail 4. The non-opposing surfaces of the sliders 21 are provided with protrusions. The output end of the cylinder 5 is fixedly connected to the outside of the protrusions. The opposing surfaces of the sliders 21 are fixedly installed with inner slide plates 22. Through the fixed connection between the cylinder 5 and the sliders 21, after the bar is fixed, the cylinder 5 drives the inner slide plates 22 through the sliders 21, so that the inner slide plates 22 drive the fixing mechanism 3, so that the bar is close to the saw blade 8, and the saw blade 8 gradually penetrates the bar after contacting it for cutting processing. A sliding groove plate 23 is fixedly installed between the inner slide plates 22, and the top of the inner slide plates 22 is fixedly connected to the bottom of the fixing mechanism 3.

[0041] A groove is formed at the center of the top of the sliding plate 23, and a support plate 24 is slidably installed at the groove of the sliding plate 23. An elastic washer 25 is fixedly installed between the outer side of the support plate 24 and the inner wall of the sliding plate 23. The elastic washer 25 is located on the side of the support plate 24 away from the saw blade 8. A connecting plate 26 is fixedly installed on the top of the support plate 24 on the side closer to the saw blade 8. Both sides of the connecting plate 26 on the side closer to the saw blade 8 are provided with protrusions, and a top plate 27 is fixedly installed on the outer side of the protrusions of the connecting plate 26. When the material is being cut, the elastic washer 25 cooperates with the top plate 27. Utilizing the elastic deformation characteristics of the elastic washer 25, the support plate 24 can compress the elastic washer 25 to deform, thereby adjusting the position of the top plate 27. This ensures that the top plate 27 fits tightly against the side of the bar away from the saw blade 8. At the same time, the gap between the top plates 27 provides space for the saw blade 8 to penetrate deeper. The side of the top plate 27 closest to the saw blade 8 is a concave arc surface, and there are gaps between the top plates 27, which correspond to the saw blade 8.

[0042] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 8 to 10As shown, the fixing mechanism 3 includes a fixing block 31. The bottom of the fixing block 31 is fixedly connected to the top of the top material feeding mechanism 2, and an arc-shaped fixing block 34 is fixedly installed on the top of the fixing block 31. A sliding block 35 is fixedly installed on the side of the top of the arc-shaped fixing block 34 near the saw blade 8, and a threaded rod 32 is rotatably installed on the side of the top of the arc-shaped fixing block 34 away from the sliding block 35. An arc-shaped sliding block 33 is installed on the top of the arc-shaped fixing block 34. In the fixing mechanism 3, when fixing the bar, the bar is inserted between the arc-shaped fixing block 34 and the arc-shaped sliding block 33, so that the bar is positioned between the clamping plates 37. After the bar is positioned, the worker... By rotating the threaded rod 32, the arc slider 33 is connected to the threaded rod 32 by the threaded connection, and the arc slider 33 is brought close to the arc fixed block 34 under the restriction of the sliding block 35. The sliding block 38 drives the clamping plate 37 through the inner arc plate 36, so that the clamping plate 37 clamps and fixes the bar. At the same time, during clamping, the characteristics of the rubber material of the clamping plate 37 are used to deform the clamping plate 37 under the contact pressure with the bar and fit against the surface of the bar. The inner wall of the arc slider 33 is connected to the outer thread of the threaded rod 32, and the side of the arc slider 33 close to the sliding block 35 slides and adapts to the inner wall of the sliding block 35.

[0043] Both the arc-shaped slider 33 and the arc-shaped fixed block 34 have arc-shaped grooves at their center positions on their opposing surfaces, and arc-shaped sliding grooves are formed in both of these grooves. The depth of the arc-shaped sliding grooves gradually decreases in the clockwise direction. Sliding blocks 38 are slidably installed in the arc-shaped sliding grooves of both the arc-shaped slider 33 and the arc-shaped fixed block 34. During cutting, when the bar comes into contact with the rotating saw disc 8, the rotating saw disc 8 exerts a force on the bar, causing the bar to tend to rotate clockwise while cutting. At this time, the arc-shaped fixed block 34 and the arc-shaped slider 33 utilize the arc-shaped sliding grooves to rotate clockwise. With the characteristic of gradually decreasing directional depth, when the bar tends to rotate during cutting, the friction between the clamping plate 37 and the bar is used to transfer the force to the sliding block 38 through the inner arc plate 36, causing the sliding block 38 to rotate clockwise at the arc groove, increasing the clamping force on the bar. The inner arc plate 36 is fixedly installed on the opposite surfaces of the sliding block 38, and the opposite surfaces of the inner arc plate 36 are provided with slots. The clamping plate 37 is fixedly installed at the slots of the inner arc plate 36. The clamping plate 37 is made of rubber.

[0044] In use, the power fitting rod to be cut is inserted into the fixing mechanism 3. The worker adjusts the position of the rod so that the cutting position of the plate corresponds to the position of the saw disc 8. Then the worker adjusts the fixing mechanism 3 to fix the rod. Finally, the motor 6 and cylinder 5 are started, so that the motor 6 drives the saw disc 8 to rotate at high speed. At the same time, the cylinder 5 drives the fixing mechanism 3 through the material lifting mechanism 2 to bring the rod close to the saw disc 8. The high-speed rotating saw disc 8 is used to cut the rod to be cut.

[0045] When the motor 6 drives the saw disc 8, the motor 6 drives the rotating shaft 9 to rotate inside the protective cover 7. Through the fixed plate 13 fixedly installed on the outside of the rotating shaft 9, the fixed plate 13 is fixedly connected to the saw disc 8. When the fixed plate 13 rotates with the rotating shaft 9, it synchronously drives the saw disc 8 to rotate at high speed inside the protective cover 7. During the rotation, the saw disc is cut by contact with the bar. At the same time, during the cutting process, the washer ring 12 contacts both sides of the saw disc 8. The contact between the washer ring 12 and the saw disc 8 on the outside of the saw disc 8 near the cutting edge limits the offset of the saw disc 8. At the same time, when fixing the saw disc 8, the screw sleeve 10 cooperates with the fixed plate 13. After the saw disc 8 is fixed to the fixed plate 13 by the nut, the screw sleeve 10 is connected to the rotating shaft 9 by the thread. The screw sleeve 10 drives the inner ring washer 14, so that the inner ring washer 14 fits tightly with the saw disc 8, and the saw disc 8 is pressed towards the fixed plate 13.

[0046] In the top material mechanism 2, the cylinder 5 is fixedly connected to the slider 21. After the bar is fixed, the cylinder 5 drives the inner slide plate 22 through the slider 21. The inner slide plate 22 drives the fixing mechanism 3 to bring the bar closer to the saw blade 8. After the saw blade 8 contacts the bar, it gradually penetrates into the bar for cutting. When installing the bar, the elastic washer 25 cooperates with the top material plate 27. The elastic deformation characteristics of the elastic washer 25 are used to compress the elastic washer 25, thereby adjusting the position of the top material plate 27. This allows the top material plate 27 to fit tightly against the side of the bar away from the saw blade 8. At the same time, the gap between the top material plates 27 provides space for the saw blade 8 to penetrate.

[0047] In the fixing mechanism 3, when fixing the rod, the rod is inserted between the arc-fixed block 34 and the arc-slider block 33, so that the rod is positioned between the clamping plates 37. After the rod's position is adjusted, the worker rotates the threaded rod 32, and through the threaded connection between the arc-slider block 33 and the threaded rod 32, the arc-slider block 33 is brought closer to the arc-fixed block 34 under the restriction of the sliding block 35. This causes the sliding block 38 to drive the clamping plate 37 through the inner arc plate 36, so that the clamping plate 37 clamps and fixes the rod. At the same time, during clamping, the rubber material of the clamping plate 37 is used to deform the clamping plate 37 under the contact pressure with the rod. The saw blade 8 is attached to the surface of the bar. During cutting, when the bar comes into contact with the rotating saw blade 8, the rotating saw blade 8 exerts a force on the bar, causing the bar to tend to rotate clockwise. At this time, the arc groove of the arc fixed block 34 and the arc sliding block 33 takes advantage of the characteristic that the depth of the arc groove gradually decreases in the clockwise direction. During cutting, when the bar tends to rotate, the friction between the clamping plate 37 and the bar is used to transfer the force to the sliding block 38 through the inner arc plate 36, causing the sliding block 38 to tend to rotate clockwise at the arc groove, thus increasing the clamping force on the bar.
