Abstract
The utility model discloses a kind of engine toothed chain carrier bar continuous stamping die, it comprises the circular hole process tool be arranged on mould, punch A, tear drift, blanking die, it also comprises ejector and brute spring, described ejector is arranged on and tears below drift, be fixedly connected with brute spring below described ejector, described ejector upper surface is fixed with punch B, and this punch B is identical with the punch A diameter on mould.This stamping die utilizes ejector and tears drift pressing, ensures that carrier bar does not bend, and the fixing punch B on ejector ensures that chain panel aperture does not deform.
Description
Technical field
The utility model belongs to engine chain production technology, is specifically related to a kind of carrier bar stamping die.
Background technology
The quality of engine depends on the quality of each main parts size, and chain quality is one of principal element affecting engine quality.
Carrier bar is the important composition parts of chain, and the punch forming for carrier bar generally adopts stamping progressive die.The required precision of engine toothed chain chain plate flatness is higher, but current existing mould is when processing engine toothed chain carrier bar, because of the requirement of punching press fineness, mould punching gap is less, carrier bar can be caused when punching press to produce bending, aperture distortion, chain plate flatness can not meet the demands, and directly affects chain work quality.
Summary of the invention
In order to overcome the above-mentioned defect that prior art field exists, the purpose of this utility model is, provides a kind of engine toothed chain carrier bar continuous stamping die, this mould adds smooth station, to improve chain plate flatness precision.
The engine toothed chain carrier bar continuous stamping die that the utility model provides, it comprises the circular hole process tool be arranged on mould, punch A, tears drift, blanking die, it also comprises ejector and brute spring, described ejector is arranged on and tears below drift, and be fixedly connected with brute spring below described ejector, during work, brute spring applies upward pressure to ejector, described ejector upper surface is fixed with punch B, and this punch B is identical with the punch A diameter on mould.
The engine toothed chain carrier bar continuous stamping die that the utility model provides, its beneficial effect is, it utilizes ejector and tears drift pressing, ensure that carrier bar does not bend, fixing punch B on ejector ensures that chain panel aperture does not deform, this Mould Machining carrier bar out meets the requirement of engine toothed chain, is applicable to being processed into that the life-span is long, speed is high, be applicable to vibration, noise is low and can carry larger engine toothed chain.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the utility model embodiment;
Fig. 2 is the top view of Fig. 1.
Mark in figure:
1. material strip; 2. punch A; 3. tear drift; 4. ejector; 5. brute spring; 6. blanking die, 7. carrier bar, 8. punch B, 9. circular hole rough lumber process tool, 10. circular hole essence cuts process tool.
Detailed description of the invention
With reference to the accompanying drawings, in conjunction with an embodiment, what provide the utility model is described in detail.
Embodiment
With reference to Fig. 1-Fig. 2, a kind of engine toothed chain carrier bar continuous stamping die of the present embodiment, it comprises the circular hole roughing tool 9 be arranged on mould, circular hole finishing tool 10, punch A2, tear drift 3, blanking die 6, it also comprises ejector 4 and brute spring 5, described ejector 4 is arranged on and tears below drift 3, be fixedly connected with brute spring 5 below described ejector 4, described ejector 4 upper surface is fixed with punch B8, and this punch B8 is identical with the punch A2 diameter on mould.
During processing material strip 1, first engine toothed chain carrier bar continuous stamping die of the present utility model carries out circular hole rough lumber processing to material strip 1, circular hole essence cuts processing; Then carry out profile to tear, tear that the degree of depth is material thickness 80% ~ 90%, in tearing procedures, tear that drift 3 is applied with ejector 4 pairs of parts simultaneously, downforce, ejector 4 with tear drift 3 pressing and ensure that carrier bar 7 does not bend, punch B8 guarantee carrier bar 7 aperture that ejector 4 is placed does not deform; Finally carry out carrier bar 7 blanking by blanking die 6.
Claims (2)
