Abstract
The utility model discloses a symmetrical S-shaped curling die. The symmetrical S-shaped curling die comprises an upper die base, a left male die, a right male die and a female die. The upper die base is provided with a left movable groove and a right movable groove symmetrically. The left male die is movably arranged in the left movable groove through a first shaft. The right male die is movably arranged in the right movable groove through a second shaft. The female die is provided with a left forming groove and a right forming groove. The left side wall of the left forming groove is a beveled edge with the narrow upper portion and the wide lower portion, the right side wall of the left forming groove is a beveled edge with the wide upper portion and the narrow lower portion, and the left side wall and the right side wall of the left forming groove are connected through a half-round bottom edge. The structure of the right forming groove is in mirror symmetry with the left forming groove. The left forming groove is matched with the left male die. The right forming groove is matched with the right male die. According to the symmetrical S-shaped curling die, S-shaped bend forming can be finished at a time, two-time material returning is not needed, and therefore machining efficiency is high and machining performance is good.
Description
Technical field
The utility model relates to the cold punching technology processing technique field, is specifically related to a kind of symmetrical S shape crimping mould.
Background technology
The routine work operation of S shape crimping workpiece needs twice, promptly carries out the bending of first road earlier and is shaped, and carries out the bending second time again and is shaped.Two procedures need accurately be in place workpiece, and needs twice material returned, and therefore not only working (machining) efficiency is low, and the workpiece deflection takes place easily or move to cause the workpiece irregular problem in back that finally is shaped.Therefore need design and develop a kind of compound die that can carry out once-forming, to overcome the problems referred to above to the workpiece of S shape bead structure.
Summary of the invention
The purpose of this utility model is to provide a kind of symmetrical S shape crimping mould, can in the one stroke of punch press, finish the bending forming of the workpiece of S shape bead structure, need not twice material returned, therefore working (machining) efficiency height, and effectively reduce the workpiece deflection or move and cause finally the be shaped probability of happening of the irregular problem in back of workpiece.
To achieve these goals, the technical scheme that the utility model proposes is:
A kind of symmetrical S shape crimping mould, comprise upper bolster, left punch, right punch, die, described upper bolster is symmetrically arranged with left loose slot, right loose slot, and described left punch is movably set in the described left loose slot by axle one, and described right punch is movably set in the described right loose slot by axle two; Described die is provided with left grooving, right grooving, and described left grooving left side wall is up-narrow and down-wide hypotenuse, and described left grooving right side wall is a hypotenuse wide at the top and narrow at the bottom, connects by semicircle base between described left grooving left side wall and the right side wall; Described right grooving structure becomes the mirror image symmetry with described left grooving, and described left grooving cooperates with described left punch, and described right grooving cooperates with described right punch.
As the further improved symmetrical S shape crimping mould of the utility model, described upper bolster bottom is provided with binder block, is provided with elastomer between described binder block and the described upper bolster.Described binder block is used for fixing machining sheet, prevents that its slip, skew from causing the not good or drip molding of processing effect to be delivered for use.
As the further improved symmetrical S shape crimping mould of the utility model, described elastomer is spring or spring glue.
As the further improved symmetrical S shape crimping mould of the utility model, two ends, the described die upper surface left and right sides are provided with limited step.Described limited step is used to limit the putting position of machining sheet, with the raising operation degree of accuracy and uniformity, and the utilization rate of raising sheet material.
A kind of symmetrical S shape crimping mould provided by the utility model, can in the one stroke of punch press, finish the bending forming of the workpiece of S shape bead structure, need not twice material returned, therefore working (machining) efficiency height, and effectively reduce the workpiece deflection or move and cause finally the be shaped probability of happening of the irregular problem in back of workpiece.

The specific embodiment
In order to deepen to understanding of the present utility model, the utility model is done describing in further detail below in conjunction with drawings and Examples, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Shown in Fig. 1-3, the symmetrical S shape crimping mould that present embodiment provided, comprise upper bolster 1, left punch 2, right punch 3, die 4, described upper bolster 1 is symmetrically arranged with left loose slot 5, right loose slot 6, described left punch 2 is movably set in the described left loose slot 5 by axle 1, and described right punch 3 is movably set in the described right loose slot 6 by axle 2 13; Described die 4 is provided with left grooving 8, right grooving 9, and described left grooving 8 left side walls are up-narrow and down-wide hypotenuse, and described left grooving 8 right side walls are hypotenuse wide at the top and narrow at the bottom, connects by semicircle base between described left grooving 8 left side walls and the right side wall; 8 one-tenth mirror image symmetries of described right grooving 9 structures and described left grooving, described left grooving 8 cooperates with described left punch 2, and described right grooving 9 cooperates with described right punch 3.
Further improve as present embodiment, described upper bolster 1 bottom is provided with binder block 10, is provided with elastomer 11 between described binder block 10 and the described upper bolster 1.Described elastomer 11 is spring or spring glue.
Further improve as present embodiment, two ends, the described die 4 upper surface left and right sides are provided with limited step 12.Described limited step 12 is used to limit the putting position of machining sheet, with the raising operation degree of accuracy and uniformity, and the utilization rate of raising sheet material.
During work, upper bolster 1 is descending, and after left punch 2, right punch 3 touched left grooving 8, right grooving 9, inwardly upset was finished symmetrical S shape crimping forming operation thereby cooperate with left grooving 8, right grooving 9 under the sidewall effect.
The symmetrical S shape crimping mould that present embodiment provided, can in the one stroke of punch press, finish the bending forming of the workpiece of S shape bead structure, need not twice material returned, therefore working (machining) efficiency height, and effectively reduce the workpiece deflection or move and cause finally the be shaped probability of happening of the irregular problem in back of workpiece.
