Description
Technical field the present invention relates to a kind of hydraulic tensioning die device, can be widely used in tensioning member pressure forming process.
The existing drawing die device of background technology, tensioning member generally only has press ram one-way force applying press molding, and plastic force is unstable, and stretched part forming quality is poor, easily occurs waste product.Cause cost on the one hand to increase, also reduce production efficiency on the other hand.
The hydraulic tensioning die device that summary of the invention the object of the present invention is to provide a kind of bidirectional force applying press molding, workpiece quality is good, safe and reliable, production efficiency is high, cost is low, with short production cycle.
In order to achieve the above object, hydraulic tensioning die device of the present invention, comprise the ring flange being arranged on press feet, be arranged on the hydraulic jack of ring flange bottom, be arranged on the piston rod on oil cylinder, die pad is on the piston rod installed, be arranged on the lead for die pad guiding on ring flange, be arranged on the several sleeves on die pad, central ejector rod on sleeve and side push rod is arranged on by safety pin, be arranged on the fairlead led in press bench hole and for central ejector rod and side push rod, the die shoe led on the table and for central ejector rod and side push rod is installed, be arranged on the convex counterdie on die shoe, to be arranged on convex counterdie and with the edge mould of workpiece groove, be arranged on the upper bolster on press ram, be arranged on the spill patrix on upper bolster, be arranged on the upper limit travel switch on forcing press column and lower limit travel switch.
Hydraulic tensioning die device of the present invention, both can realize the stretch forming of workpiece, can realize ejecting of workpiece again.
Hydraulic tensioning die device of the present invention, its operation principle is: utilize stretching principle machining sheet goods, when making it have special shape, first by mould, sheet material is not needed the portion compresses stretched, the mould of processing part is needed to move up or down, force sheet material there is no compacted part generation stretcher strain, thus complete the shape needed for goods.
Hydraulic tensioning die device of the present invention, first installs upper die and lower die, by trade union college to be tensioned on mould, then starts forcing press, slide block down, drives patrix descending; Meanwhile, Driven by Hydraulic Cylinder work, promotes counterdie, edge mould is up.Like this, just achieve workpiece bidirectional force applying press molding, and hydraulic coupling is stablized, and forming property is good.At central ejector rod to the ejecting force of counterdie, side push rod under the ejecting force of edge mould and the descending pressurization acting in conjunction of press ram, after the blank holder of patrix and edge mould clamps blank surrounding, spill patrix, convex counterdie press to workpiece simultaneously, by workpiece stretch forming.
Hydraulic tensioning die device of the present invention, structure is simple, and utilize the pressure of oil cylinder to realize to the flanging of product and stretch forming in drawing process, pressure-pad-force is stablized, dependable performance, and the life-span is long, and can easy adjustment pressure-pad-force by adjustment oil pressure.
Hydraulic tensioning die device of the present invention, by clamping mould on forcing press, can to stretch disposable shaping to part to be processed, simple to operation, improves operating efficiency.
Hydraulic tensioning die device of the present invention, the upper limit travel switch of setting and lower limit travel switch, guarantee slide block depression stroke, ensure that product size precision, and can realize Workpiece fixing and be shaped, guarantee workpiece quality, percent defective is low.
Hydraulic tensioning die device of the present invention, adopts safety pin structure, plays safeguard protection effect.When pressure exceed design make firmly time, safety pin just can cut off with proterctive equipment security of operation.Therefore, safe and reliable.
Hydraulic tensioning die device of the present invention, adopts once-forming technique, effectively reduces manufacturing procedure, can realize the continuous production in enormous quantities of this series products, enhance productivity, reduce costs, and shortens the production cycle.
Hydraulic tensioning die device of the present invention, by the workpiece groove of edge mould, holds up suitable height by workpiece metal band material, also limits metal belting edge by its stopper slot, prevents metal belting from offseting.
Hydraulic tensioning die device of the present invention, the experiment proved that, in stretch forming process, pressure-pad-force is stablized, and be evenly distributed, material flowability is good, and finished surface is smooth, without obvious concavo-convex vestige.
Hydraulic tensioning die device of the present invention, by arranging lead, can play good guide-localization effect to die pad.
Hydraulic tensioning die device of the present invention, can realize sheet material and still can not rupture under longer stretching distance, breaches the drawing die of original structure form in the limitation carrying out adding stretching distance in man-hour.
In sum, hydraulic tensioning die device of the present invention, bidirectional force applying press molding, workpiece quality is good, safe and reliable, and production efficiency is high, and cost is low, with short production cycle.
Accompanying drawing illustrates and is further described the present invention below in conjunction with accompanying drawing and embodiment.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention in FIG, hydraulic tensioning die device of the present invention, comprise the ring flange 1 being arranged on press feet, be arranged on the hydraulic jack 2 of ring flange bottom, be arranged on the piston rod 3 on oil cylinder, die pad 4 is on the piston rod installed, be arranged on the lead 5 for die pad guiding on ring flange, be arranged on the several sleeves 6 on die pad, central ejector rod 7 on sleeve and side push rod 8 is arranged on by safety pin 17, be arranged on the fairlead 9 led in press bench hole and for central ejector rod and side push rod, be arranged on the die shoe 10 led on workbench 18 and for central ejector rod and side push rod, be arranged on the convex counterdie 11 on die shoe, to be arranged on convex counterdie and with the edge mould 12 of workpiece 19 stopper slot, be arranged on the upper bolster 13 on press ram, be arranged on the spill patrix 14 on upper bolster, be arranged on the upper limit travel switch 15 on forcing press column 20 and lower limit travel switch 16.
