Description

A kind of novel exhaust end cone class part drawing die

Technical field

This utility model relates to the technical field of material during tensile molding, specifically a kind of novel exhaust end cone class part drawing die, particularly to the mechanical connecting structure of its mould.

Background technology

Exhaust end cone class part (Fig. 1) calculates the drawing numbers needed for tensioning member according to drawing coefficient, it is illustrated that part needs four set stretching dies just can complete drawing process; Due to the hardening phenomenon that multi-drawing exists, unstable product quality, manufacturing cost is significantly high.

Summary of the invention

The purpose of this utility model is in that to provide a kind of novel exhaust end cone class part drawing die, when same stretch coefficient, reduces the quantity of diel, improves the stability of product quality, reduces manufacturing cost. Concrete grammar is: by the application of a kind of novel mould structure, two molds replace original four molds, improves the stability of product quality, reduces manufacturing cost.

To achieve these goals, the technical solution of the utility model is: a kind of novel exhaust end cone class part drawing die, it is characterized in that: it includes mould body, upper mould body be connected with die, one layer of die backing plate it is provided with between die and upper mould body, the both sides of die are respectively provided with one piece of die fixed block, die place is provided with a locating sleeve, this locating sleeve is fixedly sleeved with the locating dowel being arranged on upper mould body place, lower mould body be arranged over punch, it is sequentially provided with punch retainer and convex mould pad between punch and lower mould body, wherein punch retainer is upwards close to the setting of punch lower surface, die is upwards just arranged by punch, punch outer sheath is connected to a blank holder, the outer rim place, both sides of punch lower edge and punch retainer and convex mould pad is provided with punch retainer.

The utility model discloses a kind of novel exhaust end cone class part drawing die, tablet completes the function of four set drawing dies traditionally by one-off drawing and one-shot forming.Effectively reduce number of molds, improve forming quality of products, reduce production cost, compared to existing technologies, there is prominent substantive distinguishing features and marked improvement.

Detailed description of the invention

With reference to the accompanying drawings, this utility model is further described below.

The utility model discloses a kind of novel exhaust end cone class part drawing die, it is different from prior art and is in that: it includes mould body 1, upper mould body 1 be connected with die 2, one layer of die backing plate 3 it is provided with between die 2 and upper mould body 1, the both sides of die 2 are respectively provided with one piece of die fixed block 4, die 2 place is provided with a locating sleeve 5, this locating sleeve 5 is fixedly sleeved with the locating dowel 6 being arranged on upper mould body 1 place, lower mould body 7 be arranged over punch 8, punch retainer 9 and convex mould pad 10 it is sequentially provided with between punch 8 and lower mould body 7, wherein punch retainer 9 is upwards close to the setting of punch 8 lower surface, die 2 is upwards just arranged by punch 8, punch 8 outer sheath is connected to a blank holder 13, the outer rim place, both sides of punch 8 lower edge and punch retainer 9 and convex mould pad 10 is provided with fixing plate 11.

In the specific implementation, connected by the fixing post 12 of two punch between described punch 8 and punch retainer 9 and convex mould pad 10 and lower mould body 7, the fixing post 12 of this punch runs through punch retainer 9 and convex mould pad 10, the upper end of the fixing post 12 of punch embeds below punch 8, and the lower end of the fixing post 12 of punch embeds lower mould body 7.

Exhaust end cone class part is the molding being completed part by a set of drawing die Fig. 2 and a set of shaping mould: tablet completes the function of four set cupping tools traditionally by once drawing and one-shot forming. The premise that above-mentioned production realizes is to break through the mould molding technology of end cone, the structure of Drawing Die ensures that sufficient material flows into and surface profile requirement, it is the key of novel die molding that the structure of shaping mould ensures that the requirement of the thinning rate of shape molding and top of part, elongation class and compression class mould combine.

Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, it is impossible to assert that this utility model is embodied as being confined to these explanations above-mentioned. For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, it is also possible to make some simple deduction or replace, protection domain of the present utility model all should be considered as belonging to.
