Technical field
The present invention relates to a kind of anti-rebound bend forming die of intelligence.
Background technology
For sheet materials such as stainless steel plates, it is often necessary to which the edge to sheet material carries out bending treatment.
The anti-rebound bend forming die of intelligence in correlation technique is as shown in figure 1, angular in the upper left of die ontology 100 '
Into the notch 110 ' of section generally L-shaped, the perpendicular side wall 111 ' and its bottom wall 112 ' of the notch are orthogonal, junction
It is arc transition.
The content of the invention
Present inventor observes in real work：When sheet material carries out bending and molding on the mould, due to
The effect of external force and the constraint of mould notch, the angle of bending is 90 ° and bending part arc transition.And work as after bending formed,
External force disappears and after sheet material and mould, and the coefficient of stiffiness that sheet material itself has can make bending that resilience occurs, and cause bending
Angle can be more than 90 °.
Based on the above-mentioned fact, the inventors have recognized that, if the notch of the anti-rebound bend forming die of intelligence is perpendicular
Angle between side wall and bottom wall is less than 90 °, then in shaping, the bending angle of sheet material can also be less than 90 °.And work as bending and formed
Afterwards, external force disappears and after sheet material and mould, and the part when springback capacity of bending can compensate shaping less than 90 °, is bending
Angle be exactly 90 °.
It is contemplated that at least solving one of technical problem in correlation technique to a certain extent.
Therefore, it is an object of the present invention to propose a kind of simple structure, can ensure sheet material bending angle be 90 °
The anti-rebound bend forming die of intelligence.
The anti-rebound bend forming die of a kind of intelligence according to embodiments of the present invention, including：Die ontology, the mould sheet
The upper left corner of body has a notch, and the cross-sectional configuration of the notch is into substantially L-shaped, perpendicular side wall and the notch of the notch
Angle between bottom wall is less than arc transition between 90 ° and the perpendicular side wall and the bottom wall of the notch of the notch.
Advantageously, the bottom wall of the notch is parallel with the bottom surface of the die ontology.
Advantageously, the angle between the perpendicular side wall and the bottom wall of the notch of the notch is 83 °~87 °.
Advantageously, the angle between the perpendicular side wall and the bottom wall of the notch of the notch is 85 °.
An example of the invention, the anti-rebound bend forming die of described intelligence also includes mold base, the mould
Have and the fin for extending along the longitudinal direction is formed with the lower surface of body, the section of the fin is big cyclotomy shape, the mould
There is the groove being adapted with the fin, the upper surface of the mold base is located at the left side of the groove on the upper surface of seat
Part is parallel with the bottom surface of the die ontology, the upper surface of the mold base be located at the part on the right side of the groove with it is described
