Description

Technical Field

[0001] The present invention relates to the technical field of copper bar processing, and more specifically, to an on-line sawing device for copper bars and an on-line sawing method for copper bars. Background Art

[0002] In modern industrial production, copper bars, as important conductive materials, are widely used in power transmission and distribution systems. With the growth of market demand and the requirements of technological progress, higher standards for the processing efficiency and precision of copper bars are put forward. Traditional copper bar sawing devices mostly adopt an intermittent production mode, that is, the conveyance of copper bars must be paused before each cutting, which not only limits the overall efficiency of the production line but also increases the risk of equipment wear and energy consumption.

[0003] When existing sawing devices apply a continuous on-line cutting scheme, there are usually some significant problems. First, if the synchronous control between the conveyance system and the cutting device is not precise enough, slight sliding of the copper bar is likely to occur during the return and reset stage of the cutting device, directly affecting the positioning accuracy of subsequent cutting stations. Second, speed matching errors easily lead to the cutting length of the copper bar exceeding the allowable range. Especially in the case of high-speed conveyance, the response delay of the cutting equipment easily causes the cutting position to deviate from the expectation. Finally, since there is no corresponding dynamic speed regulation mechanism to achieve precise deceleration control of the conveyance system during the cutting process, the copper bar is prone to inertial displacement at the moment of cutting, thus affecting the cutting accuracy. Therefore, we propose an on-line sawing device for copper bars and an on-line sawing method for copper bars to solve the above problems. Summary of the Invention

Detailed implementation mode

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the attached drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present invention are only based on the attached drawings of the present invention, and they do not specifically limit the present invention.

[0028] Example 1: An on-line copper busbar sawing device, as Figures 1-6As shown in the figure, it includes a machine tool 1, which is the processing carrier of this sawing device. There are two parallel slide rails 2 on the top of the machine tool 1. A plurality of receiving rollers 21 are electrically driven and slidably installed on the slide rails 2 of the machine tool 1. The receiving rollers 21 are spaced apart on the discharging side of the slide rails 2; it also includes a conveying roller 3 arranged on the feeding side of the slide rails 2 of the machine tool 1. The conveying roller 3 is used to dock and convey the incoming copper bar 100. A length meter 4 is installed on the feeding side of the conveying roller 3. The length meter 4 is used to measure the sawing length of the copper bar 100. The bottom plate of the machine tool 1 is slidably provided with a sawing mechanism 6 through a guide rail 101;The sawing mechanism 6 includes a machine housing 61 slidably mounted on the first guide rail 101. A hydraulic cylinder 5 is fixedly installed on the bottom plate of the machine tool 1, and the piston rod of the hydraulic cylinder 5 is connected to the machine housing 61. A processing plate 62 is fixedly connected to the middle of the machine housing 61. The processing plate 62 and the conveying rollers 3 are on the same horizontal plane and serve as the bearing surface for sawing the copper strip 100. The sawed copper strip 100 will be conveyed onto the processing plate 62 in the machine housing 61 after passing through the conveying rollers 3. A clamping frame 64 is slidably connected to the top of the machine housing 61 through a plurality of guide rods 63. The clamping frame 64 is an inverted "U" - shaped frame and is located above the processing plate 62. An elastic pad 641 is provided at the lower end of the clamping frame 64. The elastic pad 641 on the clamping frame 64 is used to clamp the sawed copper strip 100 conveyed on the processing plate 62. At least two cylinders 65 are fixedly installed on the top of the machine housing 61, and the piston rods of the cylinders 65 are connected to the clamping frame 64. A second guide rail 66 perpendicular to the feeding direction is provided at the bottom inside the machine housing 61. A cutting member 7 for cutting the copper strip 100 is provided on the second guide rail 66 of the machine housing 61. A frequency converter 9 is assembled on the machine tool 1. The frequency converter 9 is electrically connected to the receiving roller 21 and the conveying rollers 3 through a wire 91. The frequency converter 9 is used to synchronously control the transmission speeds of the receiving roller 21 and the conveying rollers 3. The counter 4 has a built - in controller and can control the hydraulic cylinder 5, the frequency converter 9, and the cylinders 65 at the same time. An infrared sensor 8 for monitoring the movement state of the clamping frame 64 is installed on the top of the machine housing 61. The infrared sensor 8 has a built - in controller for controlling the sawing action of the cutting member 7. When the end of the copper strip 100 is conveyed to the preset cutting position of the cutting member 7 in the machine housing 61, the counter 4 starts to measure the transmission length of the copper strip 100. The copper strip 100 moves onto the receiving roller 21 after passing through the machine housing 61. When the counter 4 measures that the copper strip 100 is conveyed to the preset cutting length, it rewrites the count. The counter 4 synchronously commands the hydraulic cylinder 5, the frequency converter 9, and the cylinders 65 through the built - in controller. The frequency converter 9 synchronously controls the receiving roller 21 and the conveying rollers 3 to work. At this time, the receiving roller 21, the conveying rollers 3, and the hydraulic cylinder 5 will work at the same speed which is lower than the normal transmission speed of the copper strip 100. The hydraulic cylinder 5 drives the entire sawing mechanism 6 to move in the feeding direction. At the same time, the cylinder 65 drives the clamping frame 64 to clamp the copper strip 100 conveyed synchronously on the processing plate 62, so that the sawing mechanism 6 can clamp the copper strip 100 and move at the same speed. Subsequently, after the infrared sensor 8 monitors the distance change of the clamping action of the clamping frame 64, the infrared sensor 8 controls the sawing member to quickly cut the copper strip 100 clamped by the clamping frame 64 through the built - in controller. After cutting, the cylinder 65 drives the clamping frame 64 to loosen. Subsequently, the hydraulic cylinder 5 drives the sawing mechanism 6 to perform a return reset movement and waits for the counter 4 to issue an instruction for the next cutting. Without interrupting the continuous conveyance of the copper strip 100, the cutting operation of each equal - distance copper strip 100 is completed at a reduced transmission speed, improving the cutting accuracy of the copper strip 100 without stopping the machine.;

[0029] Such as Figures 1-3As shown in the figure, the conveying roller 3 is composed of an electric roller 31, a guide frame 32, a limiting roller 33 and an adjusting screw 34. The electric roller 31 is installed on the slide rail 2 of the machine tool 1 near the feeding side in an electrically driven and rotatable manner. Guide frames 32 are fixedly connected to the slide rail 2 where the electric roller 31 is located. The limiting roller 33 is slidably connected between the two guide frames 32 through a connecting rod 331. The limiting roller 33 is located directly above the electric roller 31. The copper bar 100 is transmitted between the electric roller 31 and the limiting roller 33. An adjusting screw 34 is rotatably provided on one of the guide frames 32. The adjusting screw 34 is in threaded cooperation with the housing at the end of the limiting roller 33. The adjusting screw 34 is used to adjust the distance between the limiting roller 33 and the electric roller 31, so that the limiting roller 33 and the electric roller 31 can cooperate to adapt to the transmission of copper bars 100 with different thicknesses.

[0030] As Figure 2 and Figure 3 shown in the figure, an installation frame 41 is fixedly connected to the machine tool 1 near the electric drive roller. An installation block 42 is slidably connected to the installation frame 41. The meter 4 is assembled on the installation block 42. A first spring 43 is provided between the installation block 42 and the meter 4. The top surface of the measuring wheel of the meter 4 is horizontally higher than the top surface of the roller body of the electric drive roller. The transmitted copper bar 100 presses down the first spring 43 so that the measuring wheel of the meter 4 can stably fit on the surface of the copper bar 100 for measurement. A tightening bolt 44 is fixedly provided on the installation block 42. The tightening bolt 44 is used to fasten the installation block 42 that slides and adjusts its position on the installation frame 41, so that the meter 4 on the installation block 42 can meet the length measurement of the copper bar 100 transmitted at different positions.

[0031] As Figures 5-7 shown in the figure, the cutting member 7 is composed of a first motor 71, a coupling 72, a cutting machine 73 and an electric screw 74. The first motor 71 is fixedly installed on the guide rail two 66 at the bottom inside the machine shell 61. The cutting machine 73 is installed through the coupling 72 by the first motor 71. The first motor 71 is connected to the rotating shaft of the blade inside the cutting machine 73 through the coupling 72. A chute is opened in the middle of the processing plate 62 of the machine shell 61. The blade of the cutting machine 73 is located in the chute of the processing plate 62. The electric screw 74 is installed in the machine shell 61 in an electrically driven and rotatable manner. The electric screw 74 is in threaded cooperation with the housing of the first motor 71. The first motor 71 and the cutting machine 73 are driven by the electric screw 74 to reciprocate inside the machine shell 61, and cooperate with the first motor 71 to drive the blade inside the cutting machine 73 to rotate and cut the copper bar 100.

[0032] When the copper bar is produced and transferred from the copper bar extrusion line to the position of the conveying roller 3, the processing personnel first adjust the transmission distance between the limiting roller 33 and the electric roller 31 on the guide frame 32 by turning the adjusting screw 34 according to the thickness of the processed copper bar 100, so that the conveying roller 3 can effectively convey copper bars 100 with different thicknesses. Then, adjust the counter 4 on the mounting block 42 by sliding it on the mounting frame 41 according to the actual transmission position of the copper bar 100, and fix the adjusted counter 4 by tightening the bolt 44, so that the measuring wheel of the counter 4 can effectively contact and convey the copper bar 100. After the wire sawing device is started, the copper bar 100 to be cut is first fed into the transmission channel between the electric roller 31 and the limiting roller 33. When the conveyed copper bar 100 reaches the counter 4, the copper bar 100 will press the counter 4, causing the spring between the counter 4 and the mounting block 42 to compress, so that the measuring wheel of the counter 4 can tightly press the copper bar 100 and roll with the movement of the copper bar 100, real-time monitoring and recording the feeding length of the copper bar 100. When the front end of the copper bar 100 enters the sawing processing area of the processing plate 62 of the sawing mechanism 6, the counter 4 starts to accumulate and count, and continuously tracks the transmission distance of the copper bar 100. At this time, the rear end of the copper bar 100 is still pushed by the conveying roller 3, and the front end gradually extends to the receiving roller 21, forming a continuous conveying state. When the counter 4 detects that the conveying length of the copper bar 100 reaches the preset value, the counter 4 starts to re-count and immediately sends a trigger signal to the frequency converter 9, the hydraulic cylinder 5 and the air cylinder 65 through the built-in controller. The frequency converter 9 transmits signals to the conveying roller 3 and the receiving roller 21 through the wire 91, controlling and synchronously reducing the driving speeds of the conveying roller 3 and the receiving roller 21, so that the copper bar 100 moves uniformly at a speed lower than the normal transmission speed. At the same time, the hydraulic cylinder 5 is started, and the hydraulic cylinder 5 drives the entire sawing mechanism 6 to slide along the guide rail 101 in the same direction as the copper bar 100. The air cylinder 65 drives the clamping frame 64 to press down the copper bar 100 on the processing plate 62, and firmly clamps the surface of the copper bar 100 through the elastic pad 641 at the bottom, ensuring that there is no relative displacement between the entire sawing mechanism 6 and the copper bar 100. During the process of the sawing mechanism 6 slowly transmitting synchronously with the conveyed copper bar 100, the action of the clamping frame 64 clamping the copper bar 100 will trigger the infrared sensor 8, and the infrared sensor 8 activates the cutting member 7 through the controller. First, the first motor 71 is enabled, and the first motor 71 drives the cutting blade in the cutting machine 73 to rotate at a high speed through the coupling 72, and cooperates with the electric screw 74 to drive the entire cutting member 7 to quickly feed and reset laterally along the guide rail 66, thereby instantly cutting off the copper bar 100 clamped by the clamping frame 64. After the cutting is completed, the air cylinder 65 immediately retracts the piston rod and drives the clamping frame 64 to lift and release the copper bar 100. Subsequently, the hydraulic cylinder 5 drives the sawing mechanism 6 to quickly retract along the guide rail 101 to the initial position and waits for the next sawing signal from the counter 4.

[0033] Embodiment 2: On the basis of Embodiment 1, as Figure 5 and Figure 6As shown in the figure, an adjusting screw rod 10 is rotatably connected inside the casing 61, a limiting plate 11 is slidably connected to the processing plate 62, the adjusting screw rod 10 is in threaded cooperation with the limiting plate 11, the limiting plate 11 is provided with an opening corresponding to the chute of the processing plate 62, and the limiting plate 11 is used to limit the edge of the copper row 100, so that the cutting machine 73 can adapt to the cutting of copper rows 100 with different widths.

[0034] As Figures 5-7 shown in the figure, a covering member 12 is provided on the top of the outer casing of the cutting machine 73. The covering member 12 includes a mounting ring 121, a support rod 122 and a telescopic cover 123. The mounting ring 121 is fixedly connected to the outer casing at one end away from the blade cutting end of the cutting machine 73. Two support rods 122 are symmetrically and fixedly connected to the mounting ring 121 in the cutting direction. The mounting ring 121 is equipped with a telescopic cover 123 through the support rods 122. The telescopic cover 123 has elasticity. The telescopic cover 123 covers the periphery of the blade at the part where the cutting machine 73 exposes the processing plate 62, and the telescopic cover 123 is used to block the debris splashing outwards when the cutting machine 73 cuts the copper row 100.

[0035] As Figures 6-8 shown in the figure, a dust collector 131 and a collection box 13 are respectively and fixedly installed at intervals on the inner bottom of the casing 61. The outlet of the dust collector 131 is communicated with the inside of the collection box 13 through a connecting pipe 132, and the inlet of the dust collector 131 is communicated with the outer casing of the cutting machine 73 through a telescopic pipe 133. Through the suction effect of the dust collector 131 inside the casing 61, the debris generated when the cutting machine 73 saws the copper row 100 is blocked by the covering member 12 and then sucked into the dust collector 131 from the telescopic pipe 133, and discharged into the collection box 13 through the connecting pipe 132 for centralized collection.

[0036] As Figure 4 、 Figure 5 and Figure 9 shown in the figure, extrusion rods 14 are symmetrically and fixedly connected to both sides of the casing 61. The extrusion rods 14 are located inside the same-side slide rails 2. Convex rods 15 are fixedly connected to one side of the outer casing at both ends of each receiving roller 21 facing the discharging direction. A second spring 16 is arranged between adjacent receiving rollers 21 in the slide rail 2. When the sawing mechanism 6 saws a longer copper row 100, the casing 61 presses one adjacent receiving roller 21 through the extrusion rod 14, so that the convex rods 15 on the receiving roller 21 sequentially overcome the elastic force of the second spring 16 and displace synchronously, so that the distance between the receiving rollers 21 can synchronously adapt to the discharging transmission of copper rows 100 with different sawing lengths.

[0037] During the cutting process where the sawing mechanism 6 moves synchronously with the copper bar 100, the extrusion rod 14 on the moving housing 61 will extrude an adjacent receiving roller 21, causing the receiving roller 21 to sequentially extrude in the feeding direction against the elastic force of the second spring 16. After the springs between each receiving roller 21 are compressed, the transmission distance between the receiving rollers 21 can be adjusted along with the sawing mechanism 6, avoiding the situation where when the copper bar 100 is cut too short, the receiving roller 21 cannot effectively transmit the cut copper bar 100. If it is necessary to adjust the cutting width of the copper bar 100, the adjusting screw rod 10 can be rotated to drive the limiting plate 11 to move horizontally along the sliding groove of the processing plate 62, so that the limiting plate 11 can slide and adjust on the processing plate 62 to limit the position of the edge of the copper bar 100, ensuring that the blade of the cutting machine 73 can effectively cut copper bars 100 with different thicknesses and widths. When the cutting member 7 saws the copper bar 100, the telescopic cover 123 will move synchronously with the cutting machine 73. The part of the telescopic cover 123 that contacts the copper bar 100 will deform, while the part of the telescopic cover 123 that does not contact the copper bar 100 will cover the blade of the cutting machine 73. The cutting machine 73 completes the cutting of the copper bar 100 until the telescopic cover 123 touches the limiting plate 11. At this time, the metal chips generated when the blade of the cutting machine 73 cuts the copper bar 100 will be blocked by the telescopic cover 123, and then the vacuum cleaner 131 is synchronously activated, so that the vacuum cleaner 131 sucks the generated chips into the collection frame 13 through the telescopic pipe 133 and the connecting pipe 132 by negative pressure, avoiding polluting the processing environment inside the housing 61.

[0038] An on-line sawing method for copper bars 100 is as follows: S1. Place the copper bar 100 to be cut on the conveying roller 3 with the position of the limiting roller 33 adjusted, start the equipment, the electric roller 31 and the limiting roller 33 work together to make the copper bar 100 smoothly enter the machine tool 1, and the length meter 4 starts to measure the length of the copper bar 100 synchronously; S2. When the preset cutting length is reached, the frequency converter 9 reduces the overall transmission speed, the hydraulic cylinder 5 drives the sawing mechanism 6 to move synchronously with the copper bar 100, the air cylinder 65 controls the clamping frame 64 to press down and clamp the copper bar 100, the first motor 71 drives the cutting machine 73 to move along the second guide rail 66 to complete the cutting, and the infrared sensor 8 monitors and triggers the cutting action to ensure the cutting accuracy; S3. During sawing, the vacuum cleaner 131 collects the cutting chips to the collection frame 13 through the telescopic pipe 133 and the covering member 12. After cutting is completed, the air cylinder 65 raises the clamping frame 64 to release the copper bar 100, and the hydraulic cylinder 5 resets the sawing mechanism 6 and prepares for the next sawing operation.
