Detailed Description
As the specific embodiment shown in fig. 1, the utility model relates to a novel flanging mechanism that can effective control kick-backs, include with the fixed mount pad 1 of mould, set up flanging mechanism on the mount pad 1, the key is: the mounting seat 1 on still be provided with flanging mechanism complex turn over seat 2 in advance, 2 sections of turning over the seat in advance be the strip structure of L type, flanging mechanism including set up in advance 2 internal angles departments of turning over seat, the cross-section be circular shape rotatory logical groove 3 and set up in this rotatory logical groove 3, be the turn-ups pivot 4 of cylindrical structure, turn-ups pivot 4 suit in rotatory logical groove 3 and have the degree of freedom in rotatory logical groove 3 internal rotation, the periphery of turn-ups pivot 4 on be provided with along its axial setting, the cross-section be sectorial turn-ups in advance along 5, turn over in advance along 5 with the help of rotatory notch protrusion that leads to groove 3 in the rotatory logical groove 3 outside.
As shown in fig. 1 and 2, a workpiece needing flanging is horizontally placed and pressed on a male die, a mounting seat 1 is installed below an upper die, the upper die moves downwards, a flanging mechanism moves downwards with the mounting seat 1, the surface of a flanging part of a pre-flanging seat 2, which is in contact with the workpiece, bends a flanging part in advance, the mounting seat 1 continues to move downwards, a flanging rotating shaft 4 turns the workpiece downwards through the flanging part of the pre-flanging edge 5, which is in contact with the flanging part of the workpiece, and the flanging rotating shaft 4 rotates under the action of the reverse force of the workpiece on the flanging rotating shaft 4, so that the pre-flanging edge 5 is completely attached to the flanging part of the workpiece to turn the workpiece over a preset angle, and the; moment is bent in advance to the finished piece when the far-end contact of turning over seat 2 and finished piece at turn-ups mechanism increases the turn-ups through turning over in advance, turn-ups pivot 4 sets up in the finished piece department of bending and has realized less area of contact, turn over in advance along 5 traditional turn-ups sword pieces of turning over in advance of seat 2 and turn-ups pivot 4, area of contact when can effectively reducing the turn-ups, to the damage of finished piece when reducing the turn-ups, the effective control resilience obviously improves the finished piece qualification rate, sparingly mould debugging cost.
The arc center angle of the radian spanned by the notch of the rotary through groove 3 is alpha, alpha is more than 162 degrees and less than 167 degrees, the internal angle of the pre-turning edge 5 is beta, beta is more than 70 degrees and less than 120 degrees.
As shown in fig. 4 and 5, the inner angle β of the pre-flanging edge 5 and the notch α of the rotary through groove 3 can make the flanging rotating shaft 4 completely turn and fold the workpiece into a certain angle by the rotation of the flanging rotating shaft 4 in the flanging process of the workpiece, and the pre-flanging seat 2 and the mounting seat 3 do not need to rotate, so that the operation difficulty is reduced, and the space is saved.
As shown in fig. 1 or fig. 2, the flanging mechanism further includes an adjusting shim 6 disposed between the mounting base 1 and the mold.
Because the stroke of the upper die is fixed, the stroke of the mounting seat 1 can be increased by increasing the thickness of the adjusting gasket 6, the stroke end point of the flanging rotating shaft 4 is closer to the lower part, the flanging angle of the workpiece is larger by the flanging rotating shaft 4, and the flanging angle of the workpiece is controlled by increasing or reducing the thickness of the adjusting gasket 6.
As shown in fig. 3, the mounting base 1 is further provided with an adjusting groove 7, an adjusting key 8 is arranged in the adjusting groove 7, and the adjusting key 8 abuts against the back of the pre-tilting base 2 and is fixedly connected with the adjusting groove 7.
The adjusting key 8 has a fixing effect on the pre-turning seat 2, the thickness size can be changed by changing the position of the adjusting key 8 in the adjusting groove 7 or replacing the adjusting key 8, and then the position of the pre-turning seat 2 is adjusted, and the transverse distance between the pre-turning seat 2 and the male die as well as the flanging rotating shaft 4 is changed.
