Abstract

The utility model belongs to a central hole positioning accurate-flanging die for an automobile muffler partition plate. The die comprises an upper die plate (1), an upper die base plate (3), a punch-die (4), a lower die plate (11), a lower die base plate (10), a stripper plate (9), a pressing plate (5) and a male die (8) and is characterized in that a positioning ring (7) is fixed to the center of the upper plane of the male die (8) which is installed in a central hole formed in the center of the partition plate (12), and the partition plate (12) is installed among a female die (6), the stripper plate (9) and the punch-die (4). When the central hole positioning accurate-flanging die machines the flanges of the muffler partition plate, the positioning ring and the central hole are used for positioning, uniformity of the heights of the flanges is ensured, product uniformity is improved, continuity is ensured for follow-up assembly, and working efficiency and product quality are improved. Central positioning points are concentrated, no positioning hole needs to be formed in other parts, the uniformity of the die is ensured, the strength of the die is improved, and the service life of the die is prolonged.

Description

Mobile muffler dividing plate centre bore registration flanging die
Technical field
The utility model belongs to mould, particularly a kind of mobile muffler dividing plate centre bore registration flanging die.
Background technology
Mobile muffler dividing plate needs flange, past locates by separator edge adding man-hour, positioning precision is low, cannot ensure product consistency, and flange height is inconsistent, inconsistent with silencer core body installation time gap, difficulty during follow-up assembling core body, can cause gas leak phenomenon after manual repairing, has abnormal sound, muffler cannot play sound deadening, causes product quality low.
Flange height is inconsistent, causes product quality low.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, a kind of method location that adds locating ring on dividing plate centre bore and punch that utilizes is provided, guarantee the consistent mobile muffler dividing plate centre bore registration flanging die of flange height.
The technical scheme that the utility model technical solution problem adopts is: a kind of mobile muffler dividing plate centre bore registration flanging die, comprise cope match-plate pattern, upper die plate, punch-die, lower bolster, counterdie backing plate, stripper, holding pad and punch, it is characterized in that fixing a locating ring in the upper planar central of punch, punch is contained in the centre bore of establishing at dividing plate center, and dividing plate is contained between die, stripper and punch-die.
The beneficial effects of the utility model are: this utility model is when processing muffler dividing plate flange, adopt locating ring and centre bore location, guaranteed that flange height is consistent, improve homogeneity of product, during for follow-up assembling, guarantee continuity, increase work efficiency and product quality; Centre spot is concentrated, and without at other position processing locating holes, guarantees mould integraty, increases mould strength, extends die life.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, with embodiment, illustrate.
Fig. 1 is the front view of mobile muffler dividing plate centre bore registration flanging die.
In figure: 1-cope match-plate pattern; 2-spring; 3-upper die plate; 4-punch-die; 5-holding pad; 6-die; 7-locating ring; 8-punch; 9-stripper; 10-counterdie backing plate; 11-lower bolster; 12-dividing plate.
The specific embodiment
Embodiment, with reference to accompanying drawing, a kind of mobile muffler dividing plate centre bore registration flanging die, comprise cope match-plate pattern 1, upper die plate 3, punch-die 4, lower bolster 11, counterdie backing plate 10, stripper 9, holding pad 5 and punch 8, it is characterized in that fixing a locating ring 7 in the upper planar central of punch 8, punch 8 is contained in the centre bore of establishing at dividing plate 12 centers, and dividing plate 12 is contained between die 6, stripper 9 and punch-die 4.Cope match-plate pattern 1 below center is fixed with upper die plate 3, and reeded punch-die 4 is established at the center below of upper die plate 3, and holding pad 5 is equipped with in the both sides of punch-die 4; Spring 2 is equipped with between holding pad 5 and the cope match-plate pattern 1 and both sides of upper die plate 3; On lower bolster 11, be fixed with counterdie backing plate 10, at counterdie backing plate 10 center, punch 8 be housed; On counterdie backing plate 10, the both sides of punch 8 are equipped with stripper 9; Punch 8 is corresponding with the groove of punch-die 4.
Add man-hour first by a centre bore of baffle material center processing, the diameter of the diameter in hole and locating ring 7 is suitable, and locating ring 7 is contained on punch 8.Baffle material with holes is contained on locating ring 7, realizes position fixing process.Slider of oil press moves up and down, and drives punch-die 4 to move up and down, and punch-die 4 moves down pressing component and moves down, and the edge of work runs into die 6, realizes turn-up process, can obtain the dividing plate 12 that quality is good, flange height is consistent.
