Detailed Description

The technical scheme of the invention is explained in detail in the following with the accompanying drawings:

referring to fig. 1 to 3, the embodiment of the present market discloses a stripping mechanism applied to a flanging machine. The flanging machine comprises a machine tool body 1, a plurality of groups of feeding wheel sets used for clamping and conveying flanging parts 7 are further arranged on the side wall of the machine tool body 1 along the horizontal discharging direction, each feeding wheel set comprises an upper pinch wheel 2 and a lower pinch wheel 2, the pinch wheels 2 are installed on a rotating shaft 6 on the side wall of the machine tool body 1, and the rotating shaft 6 rotates under the action of the rotating shaft.

The stripping mechanism comprises a stripping wheel 5, the stripping wheel 5 is made of plastic and is arranged on a rotating shaft 6 corresponding to the lower pinch roller 2 in the feeding wheel group at the rightmost end, namely the end closest to the discharging end, so as to rotate synchronously along with the pinch roller 2.

The diameter of the minimum enveloping circle of the stripping wheel 5 is 2mm larger than that of the pressing wheel 2.

As shown in FIG. 4, a plurality of grooves 5-1 are distributed on the circumference of the stripping wheel 5. The two groove walls of the groove 5-1 have a height difference, and when the groove 5-1 rotates above the rotating shaft 6, the height of the groove wall on the left side is greater than that of the groove wall on the right side.

The outer circular surface of the stripping wheel 5 is also circumferentially distributed with arc edges 5-2 with the same number as the grooves 5-1, the arc edges 5-2 are positioned between two adjacent grooves 5-1, and two ends of the arc edges are respectively connected with the top ends of the side walls of the grooves 5-1 at two sides. The centers of all the circular arc edges 5-2 are on the same circle.

Further, a plurality of horizontal support angle steels 4 are installed on the side wall of the machine tool body 1, and a material platform 3 which is horizontal and installed on the support angle steels 4 is further arranged on the side of the machine tool body 1.

The pinch roller 2 is positioned between the material table 3 and the machine tool body 1, and the stripping wheel 5 is positioned between the corresponding pinch roller 2 and the material table 3; the top surface of the material platform 3 is lower than the upper edge of the lower pinch roller 2 in each feeding wheel set; the right edge of the material platform 3 is positioned on the left side of the axis of the material stripping wheel 5.

In the embodiment, the workpiece processed by the flanging machine is the color-coated sheet with the thickness of less than 1mm, the color-coated sheet is soft in texture and good in plasticity, both the color-coated sheet and the color-coated sheet are supplied in a roll shape, and the color-coated sheet can be used after being unfolded without straightening during processing.

When the color-coated plate folding machine works, color-coated plates are fed from a feeding port and pass through different feeding wheel sets one by one to realize the edge folding function. When the leftmost end of the edge folding part 7 reaches the position of the pressing wheel 2 at the rightmost end, the pressing wheel 2 loses thrust on the bending plate, at the moment, along with the rotation of the stripping wheel 5, the tail end of the edge folding part 7 is just clamped in the groove 5-1 of the stripping wheel 5, and the bending plate is pushed to be separated from the machine tool body 1. At the moment, the flanging part 7 naturally sags under the action of gravity and is far away from subsequent workpieces, so that scratches among the workpieces are avoided, the manual carrying time is saved, and continuous processing is realized.

Because the workpiece has better flexibility and the stripping wheel 5 is a plastic wheel, the diameter of the plastic wheel is slightly larger than that of the pressing wheel 2, but the plastic wheel does not damage the workpiece.

In the material taking off process, the hem part 7 inevitably can rub with the surface of the material taking off wheel 5, so that the wear of the material taking off wheel 5 is caused, in the structure, due to the special shape design of the special-shaped groove 5-1 and the arc edge 5-2, no matter what the relative position of the material taking off wheel 5 and the hem part 7 is, the left edge of the hem part 7 is finally only contacted with one end, which is close to the circle center distance of the material taking off wheel 5, on the arc edge 5-2, after the part is worn, the height difference between two side walls of the groove 5-1 can be increased, so that the material taking off is easier, and the maintenance amount in the later period is reduced.
