Description

The compressor silencer continuous stamping die

Technical field

The utility model relates to a kind of mould, is specifically related to the compressor silencer continuous stamping die.

Background technology

Compressor is the core component of air temperature modification equipment, also is the core component of air-conditioning and refrigerator certainly, and compressor silencer is the parts of eliminating the compressor operating noise.The main flow mode of production of the compressor silencer that our company is traditional is produced according to certain procedures by the monomer mould, takes such mode of production production efficiency low, does not reach the effect of scale supply.

Domestic grant number is that the utility model patent of CN 202291028 discloses a kind of continuous punching die for silencer of air conditioning compressor, and the patrix of this utility model feedstock direction corresponding to counterdie is arranged with correcting hole, blanking punch, stretching convex die, sizing die, flanging die, perforating die, overlap discharging mould successively in parallel.This utility model is not pressed circumcircle and is pressed the program of inscribed circle, and the program of only having used blanking and having turned over time just means that also this utility model outer rim among producing the compressor silencer program only cut a circle.And this utility model also only has one program of stretching, only have the wall thickness of stretching place of the compressor silencer that one stretching run produce can obvious attenuation behind the circumscribed circle, the muffler of wall thickness in use has the hidden danger of perforation, has the hidden danger of breaking when bearing immense pressure.

The utility model content

Goal of the invention: the purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of continuous stamping die of high efficiency production compressor silencer is provided, reduces simultaneously the defective of the stretching place wall thickness attenuation that among production process, causes because of the stretching reason at compressor silencer.

Technical scheme: in order to realize above purpose, a kind of compressor silencer continuous stamping die described in the utility model, comprise upper die and lower die, the corresponding feedstock direction of patrix is arranged with in parallel successively: circumcircle punch, inscribed circle punch, first stretching convex die, moulding stretching convex die, shaping stretching convex die, punching three holes and mesopore punch, rush salient point punch, blanking punch; The corresponding feedstock direction of counterdie is arranged with in parallel successively: rush pilot hole and press the circumcircle die, press the inscribed circle die, just draw refreshing die, molding concave die, correcting die, punching three holes and mesopore die, rush salient point die, blanking die; Wherein, the circumcircle punch with rush pilot hole press circumcircle die, inscribed circle punch and press inscribed circle die, first stretching convex die and just draw refreshing die, moulding stretching convex die and molding concave die, shaping stretching convex die and correcting die, punching three holes and mesopore punch and punching three holes and mesopore die, rush the salient point punch with rush about salient point die, blanking punch and the blanking die difference corresponding.

More accurately reach conveniently in order to operate, as preferably, described upper die and lower die all are connected on the guide pillar.

For the various types of products of applicable production, as preferably, described circumcircle punch, inscribed circle punch, first stretching convex die, moulding stretching convex die, shaping stretching convex die, punching three holes and mesopore punch, rush salient point punch, blanking punch, rush pilot hole and press the circumcircle die, press the inscribed circle die, just draw refreshing die, molding concave die, correcting die, punching three holes and mesopore die, rush the salient point punch and blanking die all is fixed on the fixed head, this fixed head is fixed on the mould bases.

Beneficial effect: the compressor silencer continuous stamping die that the utility model provides is implementing one pressure circumcircle arranged with the program of pressing inscribed circle among the production routine, having the belling platform namely just to stretch and press cylindrical among drawing process is moulding twice programs, by this four roads production routine, can reduce in drawing process, to cause the defective of stretching place wall thickness attenuation because stretch; The mould of monomer is integrated into after the progressive die, the eight road production routines that originally carry out respectively be incorporated into one can the platform of continuous operation on, its production efficiency has obtained improving greatly.
