Detailed description of the invention

In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.

As shown in Figures 1 to 5, a kind of hexagon ring decompressor, comprise bearing, this bearing comprises the workbench 11 of placing to be punched 10, be equipped with longitudinal support arm 12 in workbench 11 both sides, on two support arms 12, be horizontally connected with respectively the Fastener 20 that can vertically move along support arm 12, specifically can on two support arms, offer the chute 14 vertically moving for Fastener 20.In the utility model, two Fasteners 20 are arranged in opposite directions, between two Fasteners 20, be arranged with the drift 30 towards stamping parts 10, this drift 30 can longitudinally rotate around two Fasteners 20, on two support arms 12, be also connected with crossbeam 13, on crossbeam 13, be provided with, promotion cylinder 40,180 ° rotation drifts 30 by drift 30 punching presses on stamping parts 10 that be connected with two Fasteners 20 respectively and on stamping parts 10, go out successively circular hole, the hexagon ring circumscribed with circular hole under driving promoting cylinder 40.The utility model first utilizes promotion cylinder 40 to make drift 30 go out circular hole on stamping parts 10, again drift 30 is rotated to 180 °, by promoting the effect of cylinder 40, utilize the other end of drift 30, hexagon ring is gone out at circumscribed edge along circular hole, at twice the material that needs on stamping parts to go out is washed to stamping parts, owing to being that circumscribed edge along circular hole carries out punching press for the second time, the material that need to wash from is less, the contact area of the end of drift 20 and stamping parts 10 is less, be that the stress that is subject on stamping parts is less, can be at the residual burr in hexagon ring edge when punching press for the second time.

Concrete, the drift 30 in the utility model comprises that cross section is the second drift 32 of the first circular drift 31 and the hollow that is regular hexagon with the coaxial cross section being connected of the first drift 31, and first drift 31 one end are inscribed within the end of the second drift 32.When punching press for the first time, the first circular drift 31 is acted on stamping parts 10, now, the first drift 31 washes from the material of contact position on stamping parts 10, forms circular hole, and circular hole edge may remain burr; When punching press for the second time, by drift 30 Rotate 180s °, make the second drift 32 aim at circular hole, because the second drift 32 is hollow form, the second drift is the cutting knife that cross section is regular hexagon, because the second drift 32 and the first drift 31 are circumscribed relation, in the time that the second drift 32 rushes at stamping parts 10, can the material on stamping parts 10 be cut open along the circumscribed edge of circular hole again, form hexagon ring, and because material is the incision that is stamped, so can there be burr at the edge of hexagon ring, guaranteed the quality of punching press.

For drift 30 can be rotated relative to two Fasteners 20, in the utility model by two Fasteners 20 respectively from the bilaterally-chucked drift 30 of the first drift 31, the end of two Fasteners 20 is all set to the arcs of recesses that can fit with the first drift 31 sidewalls, arrange in the center of the end of two Fasteners 20 right-angled intersection, can axially stretch out the dop 21 of indentation Fastener 20 inside, on the two side of the first drift 31, all establish the draw-in groove that is right-angled intersection 33 matching with dop 21.Two Fasteners 20 are in the time of clamping drift 30, cross dop 31 on Fastener 20 is stuck in the cross clamping groove 33 on the first drift 31 sidewalls, drift 30 is applied to clockwise or anticlockwise active force, under the effect of this active force, draw-in groove 33 is used to dop 21 generation extruding, make in the axial indentation Fastener 20 of dop 21, in the time that this active force orders about drift 30 and rotates 90 °, the dop 21 of cross snaps in again in the draw-in groove 33 of cross, again rotate 90 ° according to the direction of rotating, can make the other end of drift 30 aim at stamping parts 10.Utilize the dop 21 of cross and the draw-in groove 33 of cross, can be accurately by drift 30 Rotate 180s °, thus can on stamping parts 10, go out successively circular hole, go out hexagon ring along circular hole edge cuts.

Preferably, the resistance of Fastener 20 to its generation while rotation in order to reduce drift 30, can all be made as circular arc by each end of two dops 21, and each end of two draw-in grooves 33 is also all made as to circular arc.

For make dop 21 can axially stretch out in indentation Fastener 20, in the end of Fastener 20, arrange can accommodating dop 21 accommodating cavity 22, between dop 21 and accommodating cavity 22, be connected with and order about dop 21 and stretch out the back-moving spring 23 of Fastener 20 ends.In dop 21 is subject to the squeezing action indentation accommodating cavity 22 of drift 30, in the process of rotating at drift 30, in the time that dop 21 meets draw-in groove 33 again, under the effect of back-moving spring 23, dop 21 stretches out Fastener 20 and snaps in draw-in groove 33, under the elastic potential energy effect of back-moving spring 23, dop 21 can be pressed in draw-in groove 33 tightly.

Be enlightenment according to desirable embodiment of the present utility model above, by above-mentioned description, related personnel can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine technical scope according to claim scope.
