Abstract
The utility model discloses a composite forming die of a heat exchanger fin. The composite forming die comprises an upper die plate, a lower die plate and a cushion plate, wherein the cushion plate is arranged between the upper die plate and the lower die plate, the upper die plate is provided with a punching convex die, the lower die plate is provided with a punching concave die which is matched with the punching convex die, the cushion plate is fixedly provided with a concave die sleeve, the outer wall of the punching concave die is provided with a flange part which is matched with the inner wall of the concave die sleeve, and the lower part of the flange part is also provided with a thinning drawing part which is matched with the inner wall of the concave die sleeve. The composite forming die has the advantage that the lower part of the flange part of the outer wall of the punching concave die is provided with the thinning drawing part which is matched with the concave die sleeve, and the composite forming of punching, flanging and thinning drawing of the heat exchanger fin can be completed by the die at one time, so one working station is saved, and the production efficiency is greatly improved.
Description
Technical field
The utility model belongs to diel field, especially relates to a kind of heat exchanger fin punching, flange, the once-combined mould of ironing.
Background technology
In current air-condition heat exchanger fin stamping procedure, the molding procedure of mould for extending, punching, hole flanging, ironing, flange substep be shaped, and in order to make compact overall structure, mostly adopts extruding tool to process in mould, reduced by a station.The patrix of existing piercing and flanging operation is piercing punch, and counterdie is punch-die composite construction, is blanking die, is again flanging die, and counterdie, as punching concave die, adopts two straight wall constructions, is conducive to reduce the wearing and tearing between punch die.But this mould does not have ironing function, at the fin after piercing and flanging operation, still need to carry out ironing processing, make cost higher, production efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of heat exchanger fin composite molding die, has solved existing mold and cannot realize the problem of heat exchanger fin punching, flange, the once-combined moulding of ironing.
The utility model solves the technical scheme that its technical problem adopts: a kind of heat exchanger fin composite molding die, comprise cope match-plate pattern, lower bolster, and be arranged on the backing plate between cope match-plate pattern and lower bolster, on described cope match-plate pattern, be provided with piercing punch, on lower bolster, be provided with the punching concave die matching with piercing punch, on backing plate, be fixed with die case; The outer wall of described punching concave die is provided with the turn-up portion matching with die case inwall, and the bottom of this turn-up portion is also provided with the ironing portion suitable with die case inwall.
In order to prevent that fin from splitting in ironing process interruption, between turn-up portion and ironing portion, be also provided with fillet surface.
In order to prevent that fin is stuck in die case, affect pickup, this heat exchanger fin composite molding die also comprises device for discharging.Concrete, this device for discharging comprises the discharging cover that is arranged on die case inwall, and is arranged on the stage clip between discharging cover and piercing punch, the drift of described discharging cover and piercing punch is suitable.Further, die case inwall is provided with limited step, and discharging puts and is provided with the flange coordinating with limited step.
In order to blow material by pressure-air, prevent that punched scrap is bonded at the folded punching of appearance on sheet stock, piercing punch is provided with pore.
The beneficial effects of the utility model: the turn-up portion coordinating with die case by the outer wall setting in punching concave die and ironing portion, when patrix is descending, the drift of piercing punch has coordinated punching operation with the through hole of punching concave die, simultaneously, turn-up portion in punching concave die has coordinated overturning process with die case, continue descendingly, ironing portion and die case continue to coordinate to realize ironing; Further, in die case inside, discharging cover and stage clip are set, have effectively prevented that fin is stuck in die case, affects pickup.
Below with reference to drawings and Examples, the utility model is described in detail.

The specific embodiment
Embodiment, see also Fig. 1 to 4, a kind of heat exchanger fin composite molding die, comprise cope match-plate pattern 1, lower bolster 2, and be arranged on the backing plate 3 between cope match-plate pattern 1 and lower bolster 2, on described cope match-plate pattern 1, be provided with piercing punch 11, on lower bolster 2, be provided with the punching concave die 21 matching with piercing punch 11, on backing plate 3, be fixed with die case 31, the outer wall of described punching concave die 21 is provided with the turn-up portion 211 matching with die case 31 inwalls, and the bottom of this turn-up portion 211 is also provided with the ironing portion 212 suitable with die case 31 inwalls.
In order to prevent that fin from splitting in ironing process interruption, between turn-up portion 211 and ironing portion 212, be also provided with fillet surface 213.In order to blow material by pressure-air, prevent that punched scrap is bonded at the folded punching of appearance on sheet stock, piercing punch 11 is provided with pore 111.
As of the present utility model, further improve, this heat exchanger fin composite molding die also comprises and prevents that fin is stuck in the device for discharging in die case 31.Concrete, device for discharging comprises the discharging cover 4 that is arranged on die case 31 inwalls, and is arranged on the stage clip 5 between discharging cover 4 and piercing punch 11, described discharging cover 4 is suitable with the drift of piercing punch 11.Preferably, die case 31 inwalls are also provided with limited step 311, and discharging cover 4 is provided with the flange 41 coordinating with limited step 311.
When patrix is descending, the drift of piercing punch has coordinated punching operation with the through hole of punching concave die, simultaneously, turn-up portion in punching concave die has coordinated overturning process with die case inwall, patrix continues descending, and the ironing portion that is arranged on turn-up portion bottom continues to coordinate to realize ironing with die case inwall.The utility model is by arranging the ironing portion coordinating with die case in punching concave die outer wall turn-up portion bottom, make heat exchanger fin through this Mould Machining, once can complete the composite molding of punching, flange, ironing, save a station, production efficiency is improved greatly.
Certainly; device for discharging can also adopt other structure; on the mode that stage clip matches with push rod as adopted or die case, a upper cover offseting with stage clip is set, such conversion all can realize and prevent that fin is stuck in die case, within should being considered as falling into protection domain of the present utility model.
