Description

Technical Field

[0001] The invention belongs to the technical field of flat steel processing, and in particular relates to an electrode flat steel cutting device. Background Art

[0002] Electrode flat steel is a flat steel material with a specific shape and size, which is widely used in various electrical equipment and industrial production, especially in the welding, smelting, chemical and electronics industries. The existing production process of electrode flat steel generally includes cutting, straightening, cutting and shaping, surface treatment and packaging. During transportation, electrode flat steel may be slightly bent. Since electrode flat steel with a longer length is not easy to straighten, it is generally cut according to the customized size first. However, when the bent electrode flat steel is cut by a sawing machine, the fracture surface may not be parallel to the side wall of the electrode flat steel, resulting in the need for subsequent correction, resulting in a waste of manpower, material resources and waste of materials.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Next, refer to Figures 1 to 5 The working principle of this embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0032] The conveyor 1 drives the electrode flat steel 6 forward a set distance according to production requirements and then cuts it. The conveyor 1 is generally a roller belt.

[0033] The sliding base 23 is mounted on the support platform 21, which is located below the conveyor 1. The clamping plates 22 are slidably mounted on the sliding base 23. The linear drive unit 24 is connected to the clamping plates 22 and is used to control their position. When the transmission device stops, the linear drive unit 24 starts to drive the clamping plates 22 closer together until the electrode flat steel 6 is fixed, preventing the electrode flat steel 6 from shifting during the cutting process of the cutting device 3. The clamping plates 22 are generally provided in two groups to provide better support and prevent the electrode flat steel 6 from shifting. The linear drive unit 24 here can be a linear motor, hydraulic cylinder, electric push rod, etc.

[0034] The cutting device 3 is mounted on the support platform 21. The lifting mechanism 34 is mounted on the support platform 21, and the support frame 33 is bolted to the lifting mechanism 34. The reciprocating drive unit is mounted on the support frame 33. Both ends of the saw blade 31 are connected to the reciprocating drive unit. The reciprocating drive unit drives the saw blade 31 back and forth, and the lifting mechanism 34 drives the saw blade 31 downward, thereby cutting the electrode flat steel 6. The guide frame 32 is mounted on the lifting mechanism 34 to guide the saw blade 31. At the same time, the groove gap on the guide frame 32 is equal to the thickness of the saw blade 31, so it will scrape the debris on the saw blade 31 and accumulate it. The guide frame 32 is also equipped with a cutting fluid nozzle to spray cutting fluid on the saw blade 31 for lubrication and to flush away the debris on the saw blade 31.

[0035] The guide frame 32 is divided into a fixed portion 321 and a movable portion 322, with the fixed portion 321 and movable portion 322 being pivotally connected. A fixed rod 43 is bolted to the movable portion 322. A guide hole is defined in the fixed rod 43, and the guide rod 42 is slidably mounted within the guide hole. A pressure plate 44 and a connecting plate 45 are bolted to each end of the guide rod 42, with the pressure plate 44 located at the end closest to the conveyor 1. A first spring 41 is fitted onto the guide rod 42, with its ends elastically abutting against the connecting plate 45 and fixed rod 43, respectively. The saw blade 31 is pivotally connected to the reciprocating drive unit at both ends, with the pressure plate 44 located below the cutting edge of the saw blade 31 on the side away from the guide rod 42.

[0036] When the lifting mechanism 34 drives the guide frame 32 and the support frame 33 to move downward, the pressure plate 44 is lower and therefore contacts the electrode flat steel 6 first. If the electrode flat steel 6 is bent, its contact surface with the pressure plate 44 will not be parallel. Therefore, when the pressure plate 44 continues to press down, it will drive the movable portion 322 to rotate according to the shape of the electrode flat steel 6, so that the pressure plate 44 and the electrode flat steel 6 are in a fit state. The rotation of the movable portion 322 will drive the saw blade 31 to rotate synchronously, so that the saw blade 31 and the motor flat steel are in a vertical state. This avoids the need to subsequently correct the electrode flat steel 6, resulting in a waste of manpower, material resources, and materials. Since the two ends of the saw blade 31 are rotatably connected, the rotation of the saw blade 31 will affect the transmission of the reciprocating drive mechanism. The saw blade 31 will gradually move downward in the process of cutting the electrode flat steel 6. At this time, since the pressure plate 44 cannot move, it will push the guide rod 42 and the connecting plate 45 to stretch the first spring 41 and move upward. When the cutting is completed, the lifting mechanism 34 drives the guide frame 32 and the support frame 33 to move to the initial state, and the pressing plate 44 will return to the initial state under the action of the first spring 41. The reciprocating drive unit here includes a crank slider mechanism, a cam mechanism and a pneumatic cylinder.

[0037] Another embodiment can use multiple distance sensors on a uniform horizontal plane to detect the distance to the electrode flat steel 6. The distance sensors are arranged linearly. If the detected distances are inconsistent, it indicates that the electrode flat steel 6 is bent. A brushless motor is installed between the movable portion 322 and the fixed portion 321. The microcontroller calculates the rotation angle based on the value of the distance sensors. The brushless motor drives the movable portion 322 to rotate based on the calculated result, thereby making the saw blade 31 perpendicular to the electrode flat steel 6. This method has a simple structure but is more expensive and can be selected based on actual conditions.

[0038] The sliding base 23 is slidably mounted on the support platform 21. A servo motor 51 is mounted on the support platform 21. The output end of the servo motor 51 is connected to one end of a lead screw 53 via a coupling 52. The sliding base 23 is provided with a threaded hole for the lead screw 53. The lead screw 53 is rotatably mounted within the threaded hole, with the axial direction of the lead screw 53 parallel to the material conveying direction of the conveyor 1. An electronic level is mounted on the side where the pressure plate 44 connects to the guide rod 42 and is electrically connected to the servo motor 51. The microcontroller determines the required compensation length of the electrode flat steel 6 based on the tilt of the electronic level. It then controls the rotation of the servo motor 51 to drive the lead screw 53. This allows for precise displacement adjustment of the electrode flat steel 6 as it is cut, adjusting the relative position of the saw blade 31 and the electrode flat steel 6 to prevent deviation of the saw blade 31. When the lifting mechanism 34 drives the guide frame 32 and support frame 33 upward, the movable adjustment unit 5 drives the electrode flat steel 6 back to its initial position to prevent interference with the saw blade 31.

[0039] A cavity is provided in the pressure plate 44, and a plurality of water spray channels are provided in the pressure plate 44. One end of each of the plurality of water spray channels is connected to the cavity, and the other end is connected to the side of the bottom plate away from the guide rod 42. One end of the water inlet pipe 46 is connected to the cavity, and the other end of the water inlet pipe 46 is connected to the pump body. The cavity includes a first chamber and a second chamber, and the first chamber and the second chamber are symmetrical about the midpoint of the fixed rod 43. The water spray channels include a first channel 441 and a second channel 442. One end of the first channel 441 is connected to the first chamber, and one end of the second channel 442 is connected to the second chamber. The first channel 441 and the second channel 442 are arranged at an angle, with the other end of the first channel 441 facing the direction close to the second chamber, and the other end of the second channel 442 facing the direction close to the first chamber. The first channel 441 and the second channel 442 are arranged in an alternating manner, and the first chamber and the second chamber are respectively connected to the water inlet pipe 46.

[0040] When the lifting mechanism 34 drives the pressure plate 44 and saw blade 31 downward, the pump body activates, injecting cutting fluid into the cavity through the water inlet pipe 46. The cutting fluid is ejected from the first channel 441 and the second channel 442, cleaning the surface of the electrode flat steel 6, preventing the pressure plate 44 from pressing down on foreign matter and ensuring the accuracy of the rotary adjustment device 4. It also lubricates the electrode flat steel 6 in advance, extending the service life of the saw blade 31. The staggered arrangement of the first channel 441 and the second channel 442 prevents interference between the water flows while ensuring that the surface of the electrode flat steel 6 is cleaned.

[0041] A pressure sensor is embedded in the side of the pressure plate 44 facing away from the guide rod 42 and is electrically connected to the pump body. When the pressure plate 44 first contacts the electrode flat steel 6, the first and second channels 441 and 442 are still spraying water. This allows the cutting fluid to flow only through the gap between the pressure plate 44 and the electrode flat steel 6. This not only increases water pressure and enhances cleaning effectiveness, but also simultaneously cleans the pressure plate 44, further improving accuracy. When the pressure sensor reaches the set value, the pump body shuts off.

[0042] Telescopic rods are slidably mounted on each end of the sleeve, and a partition is provided at the middle end of the sleeve. A second spring is mounted within the sleeve, with both ends of the spring elastically supporting the partition and the telescopic rod, respectively. The other end of the telescopic rod is connected to the guide frame 32, and a guide hole is provided in the sleeve. Because the guide frame 32 needs to be adjusted according to the actual width of the electrode flat steel 6, a telescopic rod is combined with a second spring structure. The initial length and elastic modulus of the second spring are equal, so the sleeve automatically adjusts to a central position during use, facilitating the use of the present application and improving work efficiency.

[0043] In summary, the conveyor 1 moves the electrode flat steel 6 a set length. The linear drive unit 24 drives the clamping plate 22 to clamp the electrode flat steel 6 securely. The lifting mechanism 34 drives the support frame 33 and guide frame 32 downward. If the electrode flat steel 6 bends, the pressure plate 44 rotates the moving portion 322 and the saw blade 31, keeping the saw blade 31 perpendicular to the electrode flat steel 6. During this process, the pump body activates, and cutting fluid is sprayed from the first and second pipes to clean and lubricate the electrode flat steel 6 and the pressure plate 44. The reciprocating drive unit activates, driving the saw blade 31 to reciprocate and cut the electrode flat steel 6, while the lifting mechanism 34 simultaneously moves the saw blade 31 downward. The microcontroller determines the required compensation length of the electrode flat steel 6 based on the tilt of the electronic level. It then controls the rotation of the servo motor 51, which drives the lead screw 53. This fine-tunes the displacement of the electrode flat steel 6 as it is cut, ensuring that the saw blade 31's movement path remains perpendicular to the electrode flat steel 6. When the saw blade 31 completes cutting, the lifting mechanism 34 drives the guide frame 32 and the support frame 33 to move upward.
