Abstract
The utility model provides a lower die with an adjustable opening. The lower die comprises a lower die seat and a lower die body which is connected with the lower die seat, wherein the lower die body has a split structure with left and right blocks, is connected with the lower die seat through guide rails and is connected with left and right hydraulic cylinders through connecting rods, the hydraulic cylinders are fixedly installed on the lower die seat, two stop blocks are respectively fixed on two sides of the lower die seat, an adjustment gasket is arranged between each stop block and the lower die body, and the left and right hydraulic cylinders which are connected with the lower die body are synchronous hydraulic cylinders. The lower die has the advantages of simple structure, convenience in operation, good locking effect and low cost.
Description
Technical field
The utility model relates to mechanical manufacturing field, relates in particular to a kind ofly for the mould bending former, specifically refers to the counterdie that a kind of opening is adjustable.
Background technology
As everyone knows, the forming principle of mould is by the interaction of mold and bed die, by a kind of processing technology of sheet material extrusion modling, the moulding process of mould has stretching, bending, punching etc., in the mould of heavy bending, mould is larger, and the size of the size of workpiece and mould has direct relation, the sheet material of crooked different angles, different size needs the different moulds of eating cun structure, so often causes the mould kind more, cost is larger, uses also more loaded down with trivial details.
At present, in producing in the heavy bending of actual production, mould is designed to opening adjustable die formula by counterdie, by reserved locating groove is set on workbench, the position of locating groove is all according to using more size setting in actual production, when the bed die of which size of needs, the position that can modulate bed die two cutting edges, then pass through mechanical interlocking.The lower modulo operation of this structure is comparatively loaded down with trivial details, and the accuracy of manufacture is had relatively high expectations, and cost is also high, easily produces wearing and tearing in use; In use procedure, find in addition, this class mould key components and parts die shoe is whole U-shaped, in manufacture process, need with whole plate blanking, again by metal cutting machine-shaping, deflection in the very large and process of processing capacity is also more difficult control like this, sometimes needs to carry out the alignment shaping by forcing press or heating; The counterdie of this species structure is in use also cumbersome, while regulating opening size at every turn, all will unclamp all lock-screws could adjustable plate to be taken out, and after adjusting the adjustable plate size, more all lock-screws is locked.
Summary of the invention
The technical problems to be solved in the utility model is for the existing weak point of prior art, provides a kind of simple in structure, easy to operate, the adjustable counterdie of opening that locking effect is good and with low cost.
Technical solution of the present utility model is, provide following a kind of opening adjustable counterdie, comprise die shoe, the counterdie be connected with die shoe, described counterdie is two of left and right Split type structure, described counterdie is connected with die shoe by guide rail, and described counterdie is connected to hydraulic cylinder by connecting rod, and described hydraulic cylinder is fixedly mounted on die shoe.
Adopt above technical scheme, counterdie is made to split-type structural, be connected on die shoe by guide rail, can be free to slide, adjustable mainly for meeting between the counterdie cutting edge size, there is no dimension constraint; Two counterdies in left and right are connected with hydraulic cylinder respectively, have realized electric automatization control, and hydraulic cylinder can make the counterdie locking of two of left and right simultaneously, are not moved during assurance work is stressed, thereby guarantee workpiece quality and precision.
As preferably, described die shoe both sides all are fixed with block.Adopt the technical program, in bending deformation process of work piece, a component that imposes on the active force of two counterdies in left and right is horizontal direction, sets up block, can improve the stability of two counterdies in left and right.
As preferably, be provided with the adjusting pad between described block and counterdie.Adopt the technical program, adjust the spacing between the counterdie cutting edge of two of left and right by the thickness of regulating pad, to meet the workpiece bending of different size requirement.
As better, described two of the left and right hydraulic cylinder joined with counterdie is synchronous hydraulic cylinder.Adopt the technical program, immobilize mainly due to the patrix position of installing on slider of bender, two of left and right counterdie should be symmetrically distributed with the Center of Pressure of patrix, mainly for guaranteeing that Mould's Pressure Center is stablized and the quality of workpiece.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Shown in figure: 1, die shoe, 2, counterdie, 3, guide rail, 4, connecting rod, 5, hydraulic cylinder, 6, block, 7, regulate pad.
The specific embodiment
For ease of explanation, below in conjunction with accompanying drawing, the counterdie adjustable to the opening of utility model elaborates.
As shown in FIG., the counterdie that a kind of opening is adjustable, comprise die shoe 1, the counterdie 2 be connected with die shoe 1, described counterdie 2 is two of left and right Split type structure, described counterdie 2 is connected with die shoe 1 by guide rail 3, described counterdie 2 is connected to hydraulic cylinder 5 by connecting rod 4, described hydraulic cylinder 5 is fixedly mounted on die shoe 1, described die shoe 1 both sides all are fixed with block 6, be provided with between described block 6 and counterdie 2 and regulate pad 7, described two of the left and right hydraulic cylinder 5 joined with counterdie 2 is synchronous hydraulic cylinder.
During use, at first will, according to the workpiece size required precision, analyze and choose comparatively suitable cutting edge size, then by controlling the movement of hydraulic cylinder 5, drive moving left and right of two counterdies in left and right, and by selecting suitable adjusting pad 7 to be regulated, locked hydraulic cylinder 5; Use afterwards testing tool to be detected between two cutting edges distance and whether meet processing request, to be determined errorless after, patrix is slowly moved down, observe and measure patrix and whether be positioned at Mould's Pressure Center; After finally guaranteeing that above-mentioned data are errorless, carry out the pressure testing system of workpiece, if meet the workpiece size required precision fully, can carry out batch machining.
When needs carry out the different workpiece brake forming of two sizes, only hydraulic cylinder 5 need be moved to position the locking of required size, can carry out the brake forming of different size workpiece, the utility model is not subject to the constraint of size, can carry out the adjusting of arbitrary dimension, the scope of application is more extensive, and use cost is cheaper.
In the above-described embodiments, preferred forms of the present utility model is described, obviously, under inventive concept of the present utility model, still can make a lot of variations.At this, should illustrate, any change of making under inventive concept of the present utility model all will fall in protection domain of the present utility model.
