Abstract
The utility model relates to a precision hole punching and flanging die for an automobile muffler end cover. The die comprises a lower die plate (1), a lower die base plate (2), an upper die plate (11), an upper die base plate (10) and a punch (7) and is characterized in that drum type discharge rubber blocks (3) are symmetrically fixed to the upper face of the lower die base plate (2), a punch-die (4) provided with a blanking hole (12) is installed in the center of the lower die base plate (2), a first arc (14) is arranged on the external circle of the upper end of the punch-die (4), a discharge plate (5) is installed on the upper faces of the discharge rubber blocks (3) and the upper end of the punch-die (4), and a second arc (13) is arranged on the external circle of the upper end of the discharge plate (5). The precision hole punching and flanging die can achieve hole punching and flanging with only one die and one time of stamping, secondary positioning errors are eliminated, product uniformity is ensured, product precision is improved, production efficiency is high, and the die machining cost is reduced.
Description
Technical field
The utility model belongs to mould, and particularly a kind of mobile muffler end cap precision is rushed hole flanging mold.
Background technology
Mobile muffler end cap is positioned at muffler end and is connected with intake and exhaust core pipe, and middle part has circular hole to need flange; At present, add man-hour, need to manufacture two pairs of moulds, needing first punching simultaneously, and then flange, processing at twice, twice location, as produced position error, reduce product quality, when serious, cause the later stage to assemble, cannot ensure product consistency, reduce production efficiency.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of need one pair of mould, the mobile muffler end cap precision of time processing is rushed hole flanging mold continuously.
The technical scheme that the utility model technical solution problem adopts is: a kind of mobile muffler end cap precision is rushed hole flanging mold, comprise lower bolster, counterdie backing plate, cope match-plate pattern, upper die plate and drift, it is characterized in that the discharging block rubber that is fixed with cydariform symmetrical on counterdie backing plate, the punch-die of material-dropping hole is equipped with at counterdie backing plate center, and punch-die upper end cylindrical is provided with circular arc one; On discharging block rubber, with punch-die upper end handling flitch, the upper end cylindrical of stripper is provided with circular arc two.
The beneficial effects of the utility model are: this utility model only needs one pair of mould, and a punching press completes punching and flange, eliminate secondary position error and ensure product consistency, and improve Product Precision, and production efficiency is high, reduces Mould Machining expense.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, with embodiment, illustrate.
Fig. 1 is the main pseudosection that mobile muffler end cap precision is rushed hole flanging mold.
In figure: 1-lower bolster; 2-counterdie backing plate; 3-discharging block rubber; 4-punch-die; 5-stripper; 6-end cover of silencer; 7-drift; 8-hole flanging die; 9-hole flanging die block; 10-upper die plate; 11-cope match-plate pattern; 12-material-dropping hole; 13-circular arc two; 14-circular arc one.
The specific embodiment
Embodiment, with reference to accompanying drawing, a kind of mobile muffler end cap precision is rushed hole flanging mold, comprise lower bolster 1, counterdie backing plate 2, cope match-plate pattern 11, upper die plate 10 and drift 7, it is characterized in that the discharging block rubber 3 that is fixed with cydariform symmetrical on counterdie backing plate 2, the punch-die 4 of material-dropping hole 12 is equipped with at counterdie backing plate 2 centers, and punch-die 4 upper end cylindricals are provided with circular arc 1; On discharging block rubber 3, with punch-die 4 upper ends handling flitch 5, the upper end cylindrical of stripper 5 is provided with circular arc 2 13.Lower bolster 1 is equipped with counterdie backing plate 2 above, and counterdie backing plate 2 centers are fixed with punch-die 4; Cope match-plate pattern 11 is equipped with upper die plate 10 below, and upper die plate 10 is equipped with hole flanging die block 9 below, and hole flanging die 8 and drift 7 are equipped with in the center of hole flanging die block 9; The lower surface of drift 7 contacts with end cover of silencer 6 and is corresponding with material-dropping hole 12.
Add and man-hour the raw material of end cover of silencer 6 is placed on to the centre position between hole flanging die 8, drift 7 and punch-die 4, with stamping machine punching press cope match-plate pattern 11, drift 7 first contacts the donor center of end cover of silencer 6, end cover of silencer 6 centers are washed into circular hole, continuous punching carries out flanging forming by end cover of silencer 6, waste material falls from material-dropping hole 12, one-shot forming.
