Abstract
The utility model discloses a kind of automobile engine tappet cold extrusion die, relate to automobile mechanical field, to comprise on tappet frock negative mold under frock convex mold and tappet, on described tappet, frock convex mold to be positioned under tappet directly over frock negative mold, on tappet, frock convex mold overlaps with the longitudinal centre line of frock negative mold under tappet, and on tappet, frock convex mold matches with frock negative mold under tappet.Compared with the existing, the automobile engine tappet cold extrusion die of the utility model protection is once-forming, saves manpower 70%, save electric power 75%, and security is high.
Description
Technical field
The utility model relates to automobile mechanical and manufactures field, particularly a kind of automobile engine tappet cold extrusion die.
Background technology
Tappet, in each part of automobile engine, is a very important part, although the little appearance structure of part is complicated, size design precision is high.
After tappet forging blank, through drill-over, milling, mill is processed into finished product, does not have disposable former and mould.
The greatest problem existed: owing to being small pieces, fineness is high, Forging Technology error is large, and post-production personnel, and the impact of the uncertain factors such as equipment, can not ensure product consistency, and quality is unstable.
Utility model content
The purpose of this utility model is just to provide a kind of automobile engine tappet cold extrusion die, and this automobile engine tappet cold extrusion die is once-forming, saves manpower 70%, save electric power 75%, and security is high.
The technical solution of the utility model is: a kind of automobile engine tappet cold extrusion die, this automobile engine tappet cold extrusion die to comprise on tappet frock negative mold under frock convex mold and tappet, on described tappet, frock convex mold to be positioned under tappet directly over frock negative mold, on tappet, frock convex mold overlaps with the longitudinal centre line of frock negative mold under tappet, and on tappet, frock convex mold matches with frock negative mold under tappet.
Compared with prior art, the beneficial effects of the utility model are:
1, large for forging mismachining tolerance, this utility model is specially for small pieces design, and numerical control electric spark molding machine and carving machine are used in die sinking, and fineness is high, and qualification rate is high, cold-extrusion technology, and stock utilization is high;
2, for manpower, resource consumption greatly, this utility model fundamentally changes technique, once-forming, saves manpower 70%, saves electric power 75%, greatly boosts productivity, and improves seed output and quality;
3, low for security, this utility model is without the need to heat treatment, and after manually loading onto workpiece, staff only needs Switching Power Supply after leaving machine tooling region completely, can avoid injury, greatly reduce security incident.
Accompanying drawing explanation
Fig. 1 is frock convex mold overall structure schematic diagram on tappet of the present utility model;
Fig. 2 is frock negative mold overall structure schematic diagram under tappet of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of automobile engine tappet cold extrusion die as shown in Figure 1-2, to comprise on tappet frock negative mold under frock convex mold and tappet, on described tappet, frock convex mold to be positioned under tappet directly over frock negative mold, on tappet, frock convex mold overlaps with the longitudinal centre line of frock negative mold under tappet, and on tappet, frock convex mold matches with frock negative mold under tappet.
On tappet, frock convex mold comprises frock convex mold solid model cover 8 on upper punch 7 and tappet.On tappet, frock convex mold solid model overlaps 8 hollows, and upper punch 7 top is arranged on frock convex mold solid model on tappet and overlaps in 8 cavitys, and frock convex mold solid model cover 8 on tappet is stretched out in bottom.Upper punch 7 top is greater than bottom.Upper punch 7 bottom face overlaps 8 bottom faces lower than frock convex mold solid model on tappet.
Under under tappet, frock negative mold comprises die 6, low punch 5, tappet, frock negative mold solid model overlaps 4, consolidates punching 3, mat 2 and push rod 1.
Gu frock negative mold solid model overlaps 4 hollows under punching 3, tappet, under tappet, frock negative mold solid model overlaps 4 cavity tops and is less than cavity bottom.
Under die 6, solid punching 3, mat 2 are arranged on tappet from top to bottom in turn, frock negative mold solid model overlaps in 4, die 6 top is overlapped 4 tops with frock negative mold solid model under tappet and is flushed, under mat 2 bottom stretches out tappet downwards, frock negative mold solid model overlaps 4, and push rod 1 runs through solid punching 3 and mat 2 also stretches out mat 2 downwards.Mat 2 bottom face overlaps 4 bottom faces lower than frock negative mold solid model under tappet, and push rod 1 bottom face is lower than mat 2 bottom face.Low punch 5 is arranged in the cavity that solid punching 3 cavity and die 6 cavity formed, and low punch 5 top end face is lower than die 6 top end face.
On tappet, frock convex mold is fixed on forcing press top, and under tappet, frock negative mold is because fixing on forcing press bottom.During production and processing, operating personnel put blank under tappet in frock negative mold, and by switch power supply starting pressure machine, on tappet, frock convex mold is run downwards, by blank pressing formation, then upwards transports shape, and operating personnel take out the workpiece after processing.
