In this embodiment, the transmission mechanism includes a transmission rod 392, two telescoping rods 393, and two diameter adjusting gears 394; the transmission rod 392 is arranged in front and back, the lower pressing column 310 is provided with a sliding rail 312, the sliding rail 312 is arranged up and down and penetrates in front and back, and the transmission rod 392 is arranged on the sliding rail 312; one end of the transmission rod 392 is fixedly connected with the handle 391; the two telescopic rods 393 and the two diameter adjusting gears 394 are symmetrically arranged front and back, the telescopic rods 393 are vertically arranged, and the transmission rod 392 is connected to the two telescopic rods 393 and the two diameter adjusting gears 394 through bevel gear transmission; the lower ends of the two telescopic rods 393 are in transmission connection with the transmission shaft 330 through bevel gears; two diameter adjusting racks 371 are arranged at one end of the hinge plate 370 facing the lower pressing column 310, and the two diameter adjusting racks 371 on each hinge plate 370 are respectively meshed with two diameter adjusting gears 394; the lower end of the telescoping rod 393 is also connected to a support structure. When the handle 391 is rotated, the handle 391 drives the transmission rod 392 to rotate, the transmission rod 392 drives the telescopic rod 393 and the diameter adjusting gear 394 to rotate through the two groups of bevel gears respectively, so that the transmission shaft 330 is further rotated, the diameter adjusting rack 371 moves, and the diameter of the diameter adjusting mechanism and the included angle between the two inclined sections 322 are adjusted simultaneously.
In this embodiment, the supporting structure is a supporting ring 395, the telescopic rod 393 is rotatably inserted into the supporting ring 395, a protrusion is disposed at one end of the supporting ring 395 facing the transmission shaft 330, and the protrusion is inserted into a bevel gear on the transmission shaft 330, so that the bevel gear at the lower end of the telescopic rod 393 can be engaged with the bevel gear on the transmission shaft 330 for transmission.
With the above embodiments, the usage principle and the working process of the present invention are as follows:
the plate material 400 to be bent is placed on the lower die 200, and the upper die 300 is driven to move downward to bend the plate material 400.
When the bending radius needs to be changed, the handle 391 is rotated, the handle 391 drives the transmission rod 392 to rotate, and the rotation of the transmission rod 392 drives the diameter adjusting gear 394 and the telescopic rod 393 to rotate through the two groups of bevel gears respectively.
The rotation of the diameter adjusting gear 394 drives the diameter adjusting rack 371 to move, and then drives the two hinge plates 370 to be away from the lower pressing column 310, so that the included angle between the two inclined sections 322 is increased. When the included angle between the two inclined sections 322 is increased, the transmission rod 392 approaches to the transmission shaft 330 along the slide rail 312, the telescopic rod 393 is shortened, and the pressure spring 380 accumulates force, so that the diameter adjusting mechanism pushes the arc section 321 downwards.
The telescopic rod 393 rotates to drive the transmission shaft 330 to rotate through the bevel gear, the transmission shaft 330 drives the first gear 341 to rotate when rotating, the first gear 341 rotates to drive the first rack 362 to move, the four first push rods 361 slide along the limiting channels 345 and drive the four first plates 351 to be far away from the transmission shaft 330, and the third plate 353 and the second plate 352 move outwards under the drive of the first plates 351. The diameter of the diameter adjusting mechanism is increased, the diameter of the arc section 321 is changed, when the required angle is adjusted, the handle 391 stops rotating, and then bending work is carried out.
When the required bending radius is small, the rotation angle of the handle 391 is small, the distance of the first plate 351 moving outwards along the transmission shaft 330 in the radial direction is small, the locking spring 348 enables the locking block 347 to connect the first plate 351 with the third plate 353, the speed of the third plate 353 moving outwards is slow, the speed of the sliding column 364 moving outwards is further slowed, the outwards moving amount of the sliding column 364 is small, and the periphery of the diameter adjusting mechanism still approaches to a circle.
When the required bending radius is larger, the rotation angle of the handle 391 is larger, the first plate 351 moves radially outwards along the transmission shaft 330 for a larger distance, the forward sliding column 364 moves outwards at a slower speed, and the second plate 352 and the third plate 353 move outwards for a smaller distance. The first gear 341 rotates faster than the second gear 342, i.e., the second gear 342 rotates later than the first gear 341, so that the spring in the first gear 341 accumulates force. When the handle 391 is rotated continuously, the locking block 347 is disengaged from the locking groove 349 on the first plate 351, the spring releases energy, the locking block 347 no longer blocks the third plate 353 from moving outwards, the third plate 353 springs outwards rapidly, the second plate 352 is driven by the sliding column 364 to spring outwards rapidly, the second push rod 363 moves outwards rapidly along the limiting groove 346 under the driving of the sliding column 364, and the second gear 342 is driven by the second rack 365 to rotate. When the third plate 353 and the second plate 352 are in contact with the bending plate 320, the inclined surface 366 happens to be in contact with the second gear 342, the second push rod 363 is driven by the sliding column 364 to move outwards along the limiting groove 346, the inclined surface 366 pushes the second gear 342 to approach the first gear 341, the extrusion rod 343 is opposite to the through hole at the moment, when the second gear 342 approaches the first gear 341, the extrusion rod 343 is inserted into the through hole, the second gear 342 rotates synchronously with the first gear 341, the second gear 342 pushes the second plate 352 and the third plate 353 to expand outwards at an increased speed, the periphery of the diameter adjusting mechanism approaches to a circle, and the arc section 321 bends downwards to form a better bending effect. The diameter of the lower die 200 and the included angle between the two inclined sections 322, namely the bending angle, can be adjusted correspondingly when different bending diameters are faced. Different dies do not need to be replaced, the operation flow is reduced, and the bending effect is guaranteed while the machining efficiency is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
