[specific embodiment]

Below in conjunction with drawings and Examples, to the utility model activity V-type, diel is elaborated.

The activity V-type diel that the utility model is related, when the sheet type workpiece that is far smaller than length and width size for gauge carries out punch process, the problems such as punching press moulding mark, yielding, outward appearance easily scratches that have that easily run into propose.

Please refer to accompanying drawing 1, wherein show this activity V-type diel, comprise public affairs 30, bottom plate 50, lower bolster 60, die shoe 70, guide pillar 40 in cope match-plate pattern 10, train wheel bridge 20, V-type, wherein bottom plate and lower bolster are arranged on die shoe, be used for placing product to be punched, guide pillar 40 is arranged on die shoe 70 both sides, in train wheel bridge 20 and V-type, public 30 are arranged on cope match-plate pattern 10, cope match-plate pattern 10 drives public affairs 30 in train wheel bridge 20 and V-type to press down toward die shoe 70 positions along guide pillar 40, and in V-type, public 30 spike is product to be carried out to the position of punching press.

Wherein on bottom plate 50 and lower bolster 60, be provided with lower turnover panel 80, this lower turnover panel 80 comprises two rotary blades, and this rotary blade presses down crest line symmetry along public affairs in V-type, and these two active pages form a upset loose-leaf structure by a movable slider 90.And product to be punched is just placed on lower turnover panel 80, its position to be punched is to being placed between two rotary blades.

These movable slider 90 belows are provided with a spring 91, by this spring 91, are connected with die shoe 70.One end of this active page and movable slider 90 are connected through the hinge, and the other end is free end.When cope match-plate pattern 10 presses down, be pressed in movable slider 90 times, movable slider 90 pressurizeds move down, and drive lower turnover panel 80 to press down with movable slider 90 hinge point, and other one end of lower turnover panel stick up, successfully support product to be punched.

This active page and movable slider hinged end, in opposed V-type, public 30 surfaces have trapezoid boss 81, and the stringcourse gradient of this trapezoid boss 81 limits the rear folded angle of two rotary blades of turnover.Active page one end presses down, and trapezoid boss 81 holds out against mutually, and restriction rotary blade reaches predetermined angle.

Below lower turnover panel 80, the one side that 50 pairs of bottom plates deposit turnover panel is provided with W type groove one.The effect that this W type groove plays is the lower turnover panel after support upset.

This activity V-type diel, along with cope match-plate pattern pressing action, the active page by lower turnover panel rotates, and can support be subject to the thin sheet products of punching press, make it can not produce distortion, distortion or leave impression on its surface, improve product yield, enhance productivity.

The above, it is only the utility model preferred embodiment, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be not depart from technical solutions of the utility model content, according to the utility model technology, refer to any simple modification that above embodiment is done, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
