Abstract
The utility model relates to an edge-cutting punched compound die without ejecting, comprising an upper die plate, a lower die plate, a cutting-edge upper die, a cutting-edge lower die, and a punch head. The utility model is characterized in that a wall plate (8) is fixed above the lower die plate (9), a cutting-edge lower die seat (5) is fixed on the wall plate, and the center of the lower die plate is provided with a sizing block 7 whose top is positioned and supported with the punch head 6. Because of the structure, the utility model as the advantages of simple structure, small deformation of the work piece, no ejection, long service life of the die, etc.
Description
The utility model relates to the mould that forging part is carried out edge-cutting and hole-punching, and the foolproof nothing of particularly a kind of structure ejects the edge-cutting and hole-punching compound die.
In the forging part process, need the forging part of edge-cutting and hole-punching (or correction), generally be on clipping press, to carry out edge-cutting and hole-punching with the progressive die.Such forging part distortion is bigger, also need proofread and correct quality is demanding.The mould that this method needs is many, and equipment is many, the cost height, and labour intensity is big, is replaced by the edge-cutting and hole-punching compound die gradually.
Present widely used edge-cutting and hole-punching (or correction) compound die, its structure all adopts pull bar or spring ejecting structure.Be workpiece by behind the edge-cutting and hole-punching (or correction), extension bar or spring eject (recessed) mould down of cutting edge by supporting plate with workpiece.This compound die structure is complicated, and manufacturing cost is higher, and workpiece needs to be ejected just (recessed) mould of side cut after by edge-cutting and hole-punching (or correction).In the upper and lower one stroke of press ram, twice of workpiece and die and the friction of drift cutting edge.If the workpiece of pressurized correction, its horizontal direction size slightly increases.When being ejected, workpiece more increased the friction of it and die and drift cutting edge.Have to like this reduce die life.Because mould structure is complicated, the oxide skin that comes off on the workpiece is also easy-clear not.
The purpose of this utility model be to provide a kind of simple in structure, need not edge-cutting and hole-punching compound die that workpiece is ejected.
Above-mentioned purpose of the present utility model is to realize that by such technical scheme promptly the utility model comprises cope match-plate pattern, lower bolster, side cut die shoe, side cut counterdie and drift; It is characterized in that: be fixed with wallboard on the lower bolster, the side cut die shoe is fixed on the wallboard, and the centralized positioning of lower bolster is provided with parallels, the top-supported drift of parallels.
The new said structure of this practicality can further specify by accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
Referring to accompanying drawing: among the figure 1, cope match-plate pattern, 2, the side cut patrix, 3, the die forging workpiece, 4, the side cut counterdie, 5, the side cut die shoe, 6, drift, 7, parallels, 8, wallboard, 9, lower bolster.Wherein lower bolster 9 is fixed with wallboard 8 usefulness Bolt Connection, and side cut die shoe 5 is also used Bolt Connection with wallboard 8, side cut patrix and side cut die shoe Bolt Connection, and parallels 7 is located with the groove on the lower bolster 9 by the nose of its bottom and is cooperated, and can change at any time; Drift 6 is by parallels 7 centre bearings.Wherein the nose of drift 6 bottoms cooperates with the shrinkage pool at parallels top, can change as required, and side cut patrix 2 is fixed by bolts on the cope match-plate pattern 1.
The course of work of the present utility model is such: workpiece by edge-cutting and hole-punching (or proofread and correct) after, drop on the parallels 7, pick up drift 6 this moment, workpiece 3 can be pushed away or pulls out outside the mould.
The utility model is following advantage owing to said structure has:
1, simple in structure, the reliability height, cost is lower;
2, workpiece deformation is minimum, generally need not correcting process;
3, workpiece need not eject, and improve die life greatly;
4, flexible multi-purpose, can change drift as required easily, the upper and lower mould of cutting edge.
