In this embodiment, the supporting structure is a supporting ring 395, and the telescopic rod 393 is rotatably inserted into the supporting ring 395, one end of the supporting ring 395 facing the transmission shaft 330 is provided with a protrusion, 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 meshed with the bevel gear on the transmission shaft 330 for transmission all the time.
In combination with the above embodiment, the use principle and working process of the present invention are as follows:
the plate 400 to be bent is placed on the lower die 200, and the upper die 300 is driven to move downward, bending the plate 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 two groups of bevel gears respectively.
Rotation of the diameter-adjusting gear 394 drives the diameter-adjusting rack 371 to move, thereby driving the two hinge plates 370 to be far away from the lower pressing column 310, and further increasing the included angle between the two inclined sections 322. At the same time of increasing the clamping angle between the two inclined sections 322, the transmission rod 392 approaches to the transmission shaft 330 along the sliding rail 312, the telescopic rod 393 is shortened, and the pressure spring 380 stores force, so that the diameter-adjusting mechanism pushes the radian 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 rotation of the first gear 341 drives the first rack 362 to move, the four first push rods 361 slide along the limiting channel 345 and drive the four first plates 351 to be far away from the transmission shaft 330, and the third plates 353 and the second plates 352 are driven by the first plates 351 to move outwards. The diameter of the diameter adjusting mechanism is increased, the diameter of the radian section 321 is changed, and when the diameter is adjusted to a required angle, the rotation of the handle 391 is stopped, and then the bending work is performed.
When the required bending radius is smaller, the rotation angle of the handle 391 is smaller, the first plate 351 moves radially outwards along the transmission shaft 330 by a small distance, the locking spring 348 enables the locking block 347 to connect the first plate 351 and the third plate 353, the outward moving speed of the third plate 353 is slower, the outward moving speed of the sliding column 364 is further slowed down, the outward moving amount of the sliding column 364 is smaller, and the periphery of the diameter adjusting mechanism still approaches to a circle.
When the required bending radius is large, the rotation angle of the handle 391 is large, the radial outward movement distance of the first plate 351 along the transmission shaft 330 is large, the outward movement speed of the front slide column 364 is slow, and the outward movement amount of the second plate 352 and the third plate 353 is small. The rotational speed of the first gear 341 is faster than the rotational speed of the second gear 342, i.e. the rotation of the second gear 342 lags behind the first gear 341, such that the spring within the first gear 341 is power-storing. When the handle 391 is further rotated, 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 outward movement of the third plate 353, the third plate 353 rapidly pops out, the second plate 352 is driven by the slide column 364 to rapidly pop out, the second push rod 363 is driven by the slide column 364 to rapidly move outwards along the limiting groove 346, and the second rack 365 drives the second gear 342 to rotate. When the third plate 353 and the second plate 352 are in contact with the bending plate 320, the inclined surface 366 is just in contact with the second gear 342, the second push rod 363 is driven by the sliding column 364 to continuously move outwards along the limit 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, when the second gear 342 approaches the first gear 341, the extrusion rod 343 is inserted into the through hole, the second gear 342 synchronously rotates with the first gear 341, the second gear 342 pushes the second plate 352 and the third plate 353 to open outwards, the outer circumference of the diameter-adjusting mechanism is more approximate to a circle, and the radian section 321 is downwards jacked, so that the bending effect is better. The present invention allows for corresponding adjustments of the diameter of the lower die 200 and the angle between the two inclined sections 322, i.e., the bend angle, when faced with different bend diameters. And different dies are not required to be replaced, so that the operation flow is reduced, the processing efficiency is improved, and the bending effect is ensured.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
