Description

Technical Field

[0001] This invention belongs to the field of shearing machine technology, and specifically relates to a copper busbar shearing machine. Background Technology

[0002] Copper busbars, also known as copper busbars, are long conductors made of copper with rectangular or rounded corners. Simply put, they play the role of "current highways" in electrical systems, responsible for efficiently and safely transmitting and distributing large currents. Regarding the existing technology, in the heavy-duty shearing machine for thick copper busbars on the high-voltage side of transformers with authorization announcement number CN218050530U, the upper cutting blade, in conjunction with the lower cutting edge in the main blade plate, cuts the copper busbar. However, it cannot automatically position the cutting length of the copper busbar, and during the cutting process, it cannot automatically deburr the burrs formed at the cutting end of the copper busbar, thus reducing the cutting effect of the copper busbar shearing machine on the copper busbar. Summary of the Invention

The conveying plate is connected to one side of the main blade plate, the conveying roller is equidistantly connected to the top of the conveying plate, and the support leg is symmetrically connected to the bottom of the conveying plate, with the bottom of the support leg connected to the base. The deburring mechanism includes a primary vertical plate, which is connected to one side of the main blade plate, and the bottom surface of the primary vertical plate is connected to the base.

The output end of the electric telescopic rod drives the connecting plate, the pressure sensor, and the upper cutter to descend, and the copper busbar is sheared by the upper cutter and the main blade plate. After the copper busbar is sheared, if the pressure sensor does not detect any resistance formed by the copper busbar to the upper cutter, it indicates that the shearing operation of the copper busbar is completed, and the upper cutter rises to prevent the upper cutter from descending too much and damaging the sheared copper busbar, and to reduce energy consumption.

Through the air pump, and in cooperation with the main pipe, connecting pipe, and inclined pipe, the inflation and deflation of the contraction hole and the sleeve are realized. The connecting pipe is symmetrically provided with telescopic flexible hose sections to prevent the connecting pipe from affecting the movement of the primary fixing plate and the secondary fixing plate; The main pipe is equipped with a barometer to monitor the air pressure in the contraction orifice and inside the sleeve.

[0010] Preferably, the fixed-length mechanism further includes an outer cover frame plate and primary ball bearings. The outer cover frame plate is sleeved on the outer wall of the conveyor plate. The outer cover frame plate has a U-shaped structure and is connected to the primary fixing plate and the secondary fixing plate respectively. The primary ball bearings are arrayed and slidably embedded in the inner wall of the outer cover frame plate. The primary ball bearings are in contact with the conveyor plate. Through the outer cover frame plate, the primary fixing plate and the secondary fixing plate are ensured to move synchronously. The setting of the primary ball bearings reduces the influence of friction on the movement of the outer cover frame plate.

[0011] Preferably, the length-fixing mechanism further includes a baffle, a disassembly plate, and a secondary vertical plate. The baffle is located on the top of the base and is on the side opposite to the main blade plate and the conveyor plate.

The anti-detachment groove and the anti-detachment strip prevent the sliding plate from detaching from the sleeve plate. The secondary ball bearings facilitate the sliding of the copper busbars under the action of gravity.

[0013] Preferably, the deburring mechanism further includes a strip groove, a grinding groove, a grinding head, and a drive motor.

The grinding head is located at the top of the grinding groove, and there is a gap between the grinding head and the first-stage vertical plate and the second-stage vertical plate. The drive motor is connected to the side of the first-stage vertical plate opposite to the sleeve plate and the side of the second-stage vertical plate opposite to the sleeve plate by positioning bolts. The output shafts of the two drive motors pass through the first-stage vertical plate and the second-stage vertical plate, respectively, and are connected to the grinding head. The strip groove facilitates the grinding head to grind and deburr the copper busbar end. The two drive motors drive the grinding head to rotate through the output shafts. When the copper busbar slides down to its end and contacts the grinding head, the grinding head grinds and deburrs the copper busbar end.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a shearing mechanism to cut copper busbars. The length-preset mechanism on this mechanism can pre-set the distance between the baffle and the main blade plate according to the required length of the copper busbar to be cut, and can clamp and fix the copper busbar to ensure stability during shearing. After the first cut, the copper busbar is automatically moved so that the end of the copper busbar contacts the baffle again, ensuring continuous and automated shearing. For burrs generated during shearing, the two grinding heads grind and remove burrs as the cut copper busbar passes between them, further ensuring the quality of the copper busbars cut by this shearing machine. The overall device has a high degree of automation. Attached Figure Description

The output shafts of the two drive motors 410 pass through the primary vertical plate 401 and the secondary vertical plate 325 respectively, and are connected to the grinding head 409. The setting of the strip groove 407 facilitates the grinding head 409 to grind and deburr the end of the copper bus. The two drive motors 410 drive the grinding head 409 to rotate through the output shaft. When the copper bus slides down to its end and contacts the grinding head 409, the grinding head 409 grinds and deburrs the end of the copper bus.

[0027] Working principle of this invention: Personnel adjust the distance between the baffle 323 and the main blade plate 201 to a suitable level according to the required copper busbar length. Bolts are used to connect and fix the disassembly plate 324 to the base 10. When initially cutting the copper busbar, the busbar is placed on top of the conveyor roller 302, with one end of the busbar passing through the lower blade 202 and fitting against the baffle 323. The air pump 317 and the first-stage solenoid valve 315 are turned on. The air pump 317, through the main pipe 318, connecting pipe 319, and inclined pipe 314, fills the sleeve 306 with gas, thereby pushing the piston rod 307 outwards, pressing against the extrusion plate 3. When 05 contacts the copper busbar, it moves the copper busbar closer to the secondary fixing plate 310. When the copper busbar contacts the secondary fixing plate 310, the copper busbar and the pressing plate 305 can no longer move. As air continues to enter the sleeve 306, the air pressure inside the sleeve 306 gradually increases. When the air pressure reaches the threshold, the positioning and fixing of the copper busbar is completed. The barometer monitors the pressure and sends the signal to the peripheral terminal. The peripheral terminal receives the signal and controls the air pump 317 and the primary solenoid valve 315 to close, while the electric telescopic rod 206 and the drive motor 410 open. The output end of the electric telescopic rod 206 drives the connecting plate 207. The pressure sensor 208 and the upper cutter 203 descend, shearing the copper busbar through the upper cutter 203 and the main cutter plate 201. After the copper busbar is sheared, the pressure sensor 208 detects no resistance from the copper busbar to the upper cutter 203. The pressure sensor 208 sends a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the electric telescopic rod 206 to drive the connecting plate 207, pressure sensor 208, and upper cutter 203 to rise. After the output end of the electric telescopic rod 206 is fully retracted, the electric telescopic rod 206 sends a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the electric telescopic rod 206 to drive the connecting plate 207, pressure sensor 208, and upper cutter 203 to rise. When the electric telescopic rod 206 is closed, the air pump 317, the secondary solenoid valve 316, and the tertiary solenoid valve 320 are opened. The copper busbar that has been sheared and fallen to the top of the sleeve plate 402 falls to the top of the secondary ball bearing 406. Through the rolling effect of the secondary ball bearing 406 and the action of gravity, the copper busbar tilts and slides down. The two drive motors 410 that have been turned on drive the grinding head 409 to rotate through the output shaft. When the copper busbar slides down to the point where its end contacts the grinding head 409, the grinding head 409 grinds and removes burrs from the end of the copper busbar. When the copper busbar slides down and leaves the sleeve plate 402, the first shearing of the copper busbar is completed. The aforementioned activated air pump 317, through the main pipe 318, connecting pipe 319, and inclined pipe 314, fills the contraction orifice 311 with gas. Since the contraction rod 312 is connected to the blocking rod 326, the primary fixing plate 304, the secondary fixing plate 310, and the outer frame plate 321 will cause the clamping and positioning copper busbar to move towards the baffle 323. When the copper busbar contacts the baffle 323, it cannot move further, thus preventing the primary fixing plate 304 and the secondary fixing plate 310 from moving further. As air continues to enter the contraction orifice 311, the air pressure inside the contraction orifice 311 continuously increases. The barometer monitors this and, when the air pressure increases to a first preset value, sends a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the secondary solenoid valve 3. 16. The third-stage solenoid valve 320 closes, and the first-stage solenoid valve 315 opens. Simultaneously, the air pump 317 is controlled to change from the charging state to the evacuation state. The air pump 317 extracts the gas from the sleeve 306 through the main pipe 318, connecting pipe 319, and inclined pipe 314, causing the extrusion plate 305 to release its clamping and fixing of the copper busbar. When the end of the piston rod 307 away from the extrusion plate 305 contacts the first-stage fixed plate 304, the piston rod 307 can no longer move. At this time, the air pressure in the main pipe 318, connecting pipe 319, and inclined pipe 314 gradually decreases. The barometer monitors this and sends a signal to the peripheral terminal when the air pressure drops to the second preset value. The peripheral terminal receives the signal and controls the first-stage solenoid valve 315 to close, and the second-stage solenoid valve 316 and the third-stage solenoid valve 317 to open. When valve 320 opens, air pump 317 extracts gas from the two contraction holes 311 via main pipe 318, connecting pipe 319, and inclined pipe 314. This causes the first-stage fixing plate 304 and the second-stage fixing plate 310 to move the outer cover frame plate 321 away from the main blade plate 201. When the first-stage fixing plate 304 and the second-stage fixing plate 310 contact the blocking rod 326, they cannot move further. As air continues to be extracted from the contraction holes 311, the air pressure inside the contraction holes 311 decreases. The barometer monitors this and sends a signal to the peripheral terminal when the air pressure drops to the third preset value. The peripheral terminal receives the signal and controls the second-stage solenoid valve 316 and the third-stage solenoid valve 320 to close, while the first-stage solenoid valve... 315 is activated, and the air pump 317 is switched from suction to inflation. The air pump 317, through the main pipe 318, connecting pipe 319, and inclined pipe 314, fills the sleeve 306 with gas, thereby pushing the piston rod 307 outward. When the extrusion plate 305 contacts the copper busbar, it moves the copper busbar closer to the secondary fixed plate 310. When the copper busbar contacts the secondary fixed plate 310, the copper busbar and extrusion plate 305 can no longer move. As air continues to enter the sleeve 306, the air pressure inside the sleeve 306 gradually increases. When the air pressure reaches a threshold, the copper busbar shearing length is repositioned and fixed. The barometer monitors this and sends a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the air pump 317 and the primary solenoid valve 315 to close.The electric telescopic rod 206 and drive motor 410 are activated. The output end of the electric telescopic rod 206 drives the connecting plate 207, pressure sensor 208, and upper cutter 203 to descend. The upper cutter 203 and main cutter plate 201 cut the copper busbar. After the copper busbar is cut, the pressure sensor 208 can no longer detect the resistance formed by the copper busbar against the upper cutter 203. The pressure sensor 208 sends a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the output end of the electric telescopic rod 206 to drive the connecting plate 207, pressure sensor 208, and upper cutter 203 to rise. After the output end of the electric telescopic rod 206 is fully retracted, the electric telescopic rod 206 sends a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the electric telescopic rod 206 to close, while the air pump 317, the secondary solenoid valve 316, and the tertiary solenoid valve 320 open. Specifically, the copper busbar that has been sheared and fallen to the top of the sleeve plate 402 falls onto the top of the secondary ball bearing 406. Through the rolling effect of the ball bearing 406 and the combined effect of gravity, the copper busbar tilts and slides down. Meanwhile, the two activated drive motors 410 drive the grinding head 409 to rotate via their output shafts. When the copper busbar slides down to the point where its end contacts the grinding head 409, the grinding head 409 grinds and deburrs the end of the copper busbar. When the copper busbar slides down and detaches from the sleeve plate 402, the second shearing of the copper busbar is completed. This process is repeated automatically to cyclically shear the copper busbar.
