Description
Technical field
The present invention relates to diel field, be specifically related to a kind of tension disc curring die.
Background technology
Tension disc all will be used in a lot of place in the industrial production, in order to the bundles such as the electric wire of distribution at random, rope are held together, prevent from the circuit that is scattered or rope from kinking mutually to be inconvenient to distinguish, the inconvenient circuit finding needs accurately and rapidly when revising circuit or maintenance circuit together.Tension disc has a variety of pattern, a kind of tension disc having arc flanging is used in motorcycle accessories is produced, this tension disc is made up of sheet metal, the mid portion of tension disc is the flat board being provided with fixing circular hole, the part of fixing circular hole both sides is that 60 ° of angles are bent to form line ball chamber with mid portion, and conveniently the arc-shaped bayonet socket deviating from line ball chamber is made at the two ends of tension disc by the installation and removal of tension disc usually.
This tension disc first processes line ball chamber usually when manufacturing, and manually clamps down on the arc-shaped bayonet socket at two ends after line ball chamber is shaping again.This manufacture method often by the crimp of line ball chamber, can make tension disc can not stablize in use and effectively carries out pressure beam to circuit, make the machining accuracy of tension disc low when clamping down on bayonet socket.And need just can machine through multiple working procedure, working (machining) efficiency is low.
Summary of the invention
The invention is intended to provide tension disc curring die, to facilitate processing with the tension disc of arc-shaped flanging, improve machining accuracy and working (machining) efficiency.
For achieving the above object, basic technology scheme of the present invention is as follows: tension disc curring die, comprises upper bolster, punch, die, die shoe, and described die is fixed on the upper end of die shoe.The upper center of described die is provided with the boss matched with tension disc line ball chamber profile, described boss is provided with the alignment pin for locating fixing circular hole, the die of described boss arranged on left and right sides is recessed to form the shaping groove of arc-shaped downwards, and the angle between described shaping groove and boss is 60 °.Chute is provided with in described upper bolster, the lower end of described chute inwardly reduces formation limiting stand, described punch is positioned at chute, the upper end outwards circumferential spacing ring being formed and coordinate with limiting stand that extends of punch, be provided with stage clip between the top of described punch and upper bolster, the lower end of described punch is provided with the locating hole corresponding with alignment pin.The upper bolster of described punch arranged on left and right sides is fixed with rolling wheel support respectively, and the lower end of described rolling wheel support is fixed with roller.
Principle and the advantage of this programme are: during operation, are positioned on die by the tension disc blank of processed fixing circular hole by the alignment pin on boss.Upper bolster and punch is driven to move down by drive units such as hydraulic presses, the mid portion of blank is pushed down in the lower end of punch, alignment pin stretches in the locating hole of punch lower end, drive unit continues upper bolster is moved down, punch is under the effect of boss in indentation upper bolster, upper bolster drives roller the part at blank two ends to be extruded to enter in shaping groove and form line ball chamber downwards, under the shaping groove acting in conjunction of roller and arc-shaped, the two ends of blank is pressed into the high flanging of arc accuracy.Punch is set to be slidably connected in upper bolster, between upper bolster and the upper end of punch, stage clip is set, when suppressing crimp, punch both made upper bolster can continue to move down in retractable upper bolster like this, can also under the effect of stage clip by blank holding on die.Punch and die arrange locating hole and alignment pin are convenient to be positioned blank respectively, can prevent blank from moving.Die arranges the shaping groove of boss, circular arc, upper bolster arranges rolling wheel support, roller, punch, angle between boss and shaping groove is set to 60 °, like this by above-mentioned arrange can one-shot forming with the tension disc of circular arc bayonet socket, decrease molding procedure, improve working (machining) efficiency, avoid the impact of secondary operations on workpiece accuracy, improve machining accuracy.
Preferred version one, based on scheme one improve, four corners of described upper bolster lower end are provided with four guide pin bushings, and the upper end of described die shoe is provided with four guide pillars relative with guide pin bushing, and the top of guide pillar extend in guide pin bushing.Guide pin bushing and guide pillar cooperation are set like this, stable guiding can be provided for upper bolster and punch, prevent from producing skew between punch, die, affect crudy.
Preferred version two, preferably the one of is improved, and is provided with the back-moving spring be socketed on guide pillar between described guide pin bushing and die shoe.Arrange back-moving spring upper bolster and punch to be automatically reset after punching press completes, during punching press, can also cushioning effect be provided, prevent that punch decrease speed is too fast to be damaged die.
Preferred version three, preferably the one of two is improved, and the upper end of described die shoe is provided with detent, and described die is fixed by screws in detent.Arrange like this and can prevent die from die shoe, producing skew and the compacting of impact to tension disc, make the fixing more stable, firmly of die.
