Detailed Description

The present invention is further described in detail below with reference to specific examples so that those skilled in the art can more clearly understand the present invention.

As shown in fig. 1-3, an upward sheet metal flanging mechanism comprises a base plate 1, a base 2 mounted on the base plate 1, and a lower die 3 arranged on one side of the base 2, wherein a pressing plate 4 is arranged above the lower die 3, two guide grooves are formed in the base 2, a sliding block 5 is arranged in the guide groove close to one side of the lower die 3, a driving block 6 is arranged in the other guide groove, a lower flanging block 7 is arranged on the sliding block 5, and a reverse transmission assembly is arranged between the sliding block 5 and the driving block 6, so that the driving block 6 can drive the sliding block 5 to drive the lower flanging block 7 to bend a sheet metal upwards when moving downwards.

Above-mentioned embodiment is through setting up reverse drive subassembly, and when drive block 6 downstream, reverse drive subassembly can drive slider 5 drives lower mould hem piece 7 is upwards bent to the panel beating, has avoided adopting the problem that the structure is complicated that the tapered wedge mechanism brought, has reduced volume and weight, has reduced material, mould and cost of maintenance.

In a preferred technical scheme, the reverse transmission assembly comprises a rotating cam 8, and the rotating cam 8 is provided with two protruding ends which are respectively connected with the bottom end of the sliding block 5 and the bottom end of the driving block 6. The rotating cam 8 is adopted to change the moving direction, and compared with a straight lever, the stress of the cambered surface protrusion of the rotating cam 8 is stable.

As another embodiment of the reverse transmission assembly, the reverse transmission assembly may also be in the form of a gear, that is, a tooth groove is formed on the side surface of the sliding block 5 and the side surface of the driving block 6, the gear is engaged between the sliding block 5 and the driving block 6, and when the driving block 6 moves downward, the gear drives the sliding block 5 to move upward.

More preferably, the bottom end of the slider 5 and the bottom end of the driving block 6 are designed to be arc-shaped to fit the protruding ends in a specific use. When the rotating cam 8 rotates, the bottom end of the slider 5 and the bottom end of the driving block 6 slide with the protruding end of the rotating cam 8, and abrasion can be reduced by adopting an arc shape that fits the protruding end while making driving smooth.

After the reverse transmission assembly is adopted, in order to realize the automatic reset of the driving block 6 and reduce the complexity of the control of the device, the device can be provided with a reset assembly between the sliding block 5 and the base 2, so that the sliding block 5 drives the lower die flanging block 7 to reset.

Of course, it is also possible to eliminate the return means, for example, by setting the weight of the slider 5 and the weight of the drive block 6 to be unequal, and by utilizing the characteristic that the weight of the slider 5 is set to be larger than the weight of the drive block 6 because the rotating cam 8 has a rotating characteristic such that the weight of the heavy side is lowered when the weights of both ends are unequal, the slider 5 is gradually lowered automatically by the action of gravity and the drive block 6 is gradually raised automatically when the driving force of the drive block 6 is gradually withdrawn, thereby achieving the return of the apparatus.

The resetting accuracy can also be improved by adopting a resetting component, specifically, the resetting component comprises a cover plate 9 and a resetting spring 10, one end of the cover plate 9 is fixedly connected with the base 2, one end of the resetting spring 10 is fixedly connected with the bottom side of the other end of the cover plate, and the other end of the resetting spring 10 is fixedly connected with the sliding block 5. The return spring is adopted, so that the sliding block 5 and the driving block 6 can be restored to the preparation position for bending operation after each bending operation, and the return spring is simple in structure and low in cost. The reset component can also be a spring plate.

In a further preferred embodiment of the above preferred embodiment, the sliding block 5 is provided with a vertical sliding chute, the other end of the cover plate 9 is slidably connected with the vertical sliding chute, the return spring 10 is disposed in the vertical sliding chute, and the other end of the return spring 10 is fixedly connected with the bottom of the vertical sliding chute. Therefore, the reset assembly and the sliding block 5 can be integrated together, so that the structure is more compact, and the volume occupation is further reduced.

In a preferred embodiment, the width of the upper half of the slider 5 is smaller than the width of the lower half, and the top of the base 2 is attached to the side of the upper half of the slider 5. Therefore, the limiting function can be achieved, and the sliding block 5 is prevented from being separated from the upper part of the base 2.

The width of the upper half part of the driving block 6 is smaller than that of the lower half part, and the top of the base 2 is attached to the side surface of the upper half part of the driving block 6. Thus, the limit function can be realized, and the driving block 6 is prevented from being separated from the upper part of the base 2.

The working principle is as follows: when the bending is ready, a sheet metal part 11 is placed on a lower die 3, the sheet metal part 11 is pressed by a pressing plate 4, a driving block 6 is pressed, the driving block 6 moves downwards in a groove to press one protruding end of a rotating cam 8, the other protruding end of the rotating cam 8 pushes a sliding block 5 upwards, the sliding block 5 drives a lower die flanging block 7 to move upwards, the sheet metal part 11 is folded upwards, and meanwhile, a return spring 10 is compressed;

after the bending is finished, the driving block 6 is released, the return spring 10 pushes the slide block 5 to move downwards, the slide block 5 moves downwards in the groove to press one protruding end of the rotating cam 8, and the other protruding end of the rotating cam 8 pushes the driving block 6 upwards, so that the driving block is reset.

The mechanisms, components and parts of the present invention which are not described in detail are all the existing structures which exist in the prior art. Can be purchased directly from the market.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
