Abstract

The invention relates to a heterotype pipe fitting forging molding die especially suitable for non-cylinder type automatic segmental type multi-way precision forging molding manufacture, and belongs to the forging processing technical field; the heterotype pipe fitting forging molding die comprises an outer die sleeve, a core die sleeve, side punch slide blocks, side punches, a molding core die, an upper punch, a molding core die fixed pressure plate, a core die sleeve holder plate, a positioning pin, an outer drop tray, and a lower push rod; the features are that the outer die sleeve is provided with 4 tapered T-slots, the core die sleeve, and the side punch slide blocks are provided with T-shape guide rails; the 4 tapered T-slots of the outer die sleeve are respectively matched with the core die sleeve and the T-shape guide rails on the side punch slide blocks; the core die sleeve is formed by two pieces split by a central line; two sides are provided with the tapered T-shape guide rails matched with the outer die sleeve. The heterotype pipe fitting forging molding die is precise in die, high in cogging yield, and reasonable in workpiece plasticity flow direction.

Description

Section tube forging and molding mold

Technical field

The present invention relates to a kind of section tube forging and molding mold, the multidirectional finish forge moulding of automatic separating-closing type that is especially suitable for non-tubular class is manufactured, and belongs to forging and stamping processing technique field.

Background technology

Forging forming, in machining, has become and has rationally utilized metal plastic deformation to obtain few cutting and the important means without machining, utilizes the technical requirement of novel die direct forming part to become new research, innovation direction. Traditional " open type " and " enclosed " mould all exist certain defect and limitation, " open type " mould, between two die joints, all to stay certain gap and run hopper and be convenient to run material, the overlap of shaping workpiece has not only caused the waste of material like this, the later process such as trimming are also increased, " enclosed " mould is only confined to tube shape component, the easy plucking of surface of the work when discharging, and above-mentioned two kinds of moulds all cannot push with holes in side, therefore, people wish one can overcome above-mentioned shortcoming, and one-time formed section tube forging and molding mold essence mould comes out.

Summary of the invention

In order to make many sides of the workpiece compressive zone hole forming including shaped piece, thereby it is more reasonable to reach the workpiece plastic deformation flow direction, the invention provides a kind of section tube forging and molding mold.

The present invention realizes by following technology: it comprises outer die casing, core cover, and side blow head slider, side blow head, moulding core, upper punch, moulding core fixation clip, core cover supporting plate, the formations such as pallet, lower push rod, fall outward in alignment pin. It is characterized in that outer die casing is provided with 4 T-shaped grooves with tapering, cores cover and side blow head sliders and is provided with T-shaped guide rail, outer die casing be provided with 4 the T-shaped groove with tapering matches with the T-shaped guide rail on core cover, side blow head slider respectively; The two piece compositions of core cover for separating along center line; Both sides are provided with the T-shaped guide rail structure with tapering of working in coordination with outer die casing.

In above-mentioned design, mould forms matched moulds by the four stressed centering in inclined-plane with the wedge-type conical surface.

The present invention has that mould precision, billet yield are high, workpiece plastic flow is to the advantage such as reasonable.

Brief description of the drawings

Fig. 1 is front view of the present invention.

Fig. 2 is top view of the present invention.

Fig. 3 is left view of the present invention.

In accompanying drawing, 1 outer die casing, 2,10 side blow head sliders, 3 for core cover, 4,11 for side blow head tightly put screw, 5,9 for side blow head, 6 for moulding core, 7 for upper punch, 8 for moulding core fixation clip, 12 for core cover supporting plate, 13 for workpiece, 14 for lower push rod, 15 for lifting tray, 16 be alignment pin. In Fig. 2,3,3-1,3-2 are that core overlaps symmetrical two parts, 6-1,6-2 are the symmetrical two parts of moulding core, and 8-1,8-2 are the symmetrical two parts of moulding core fixation clip, and 12-1,12-2 are the symmetrical two parts of core cover supporting plate.

Detailed description of the invention

According to various product, pack the moulding core 6 of making into core retainer plate mould 3, be compacted into core moulded board 8, on the basis that a whole set of mould is located at alignment pin 16, reset completely. Due to all parts of carrying on core cover 3 and dead weight, to impel core to overlap 3 descending, and under the effect of the wedge-type conical surface on inside and outside cover die four inclined-planes, mold parting surface is combined closely, and forms " enclosed " die cavity state. Material is heated to initial forging temperature and puts into after forming core die cavity 6, the upper punch 7 being fixed on press ram pushes downwards with maximum power, impels workpiece 13 materials to do pyroplastic deformation, is crowded with die cavities and is shaped. While is due to the reaction force of the downward active force of upper punch 7 and metal material hardness, the core cover 3 that is carrying moulding core 6 is done trace operation downwards along the wedge-type conical surface on four inclined-planes, 6 two deciliters faces of moulding core are more pressed tighter, cannot form and run material and overlap, 5,9, side blow head puts in place by precalculated position. Upper punch 7 promotes up after workpiece 13 being shaped by the stroke mixing up in advance, be fixed on two connecting rods on press ram and drive the auxiliary equipment below cover dies, make top lower beam 14 increase, lifting tray 15 heads on core cover 3 and rises and split movement, workpiece 13 self fallings. Carry moulding core 6 under the effect of both sides tapering guide rail at uphill process SMIS die sleeve 3, make split movement to both sides, left and right sides drift 5,9 retrude that and then rises under side blow head slider 2,10 drives departs from workpiece 13. After stopping by predetermined stroke, taking-up work 13. Start attached pneumatic means, the slide block under lower push rod 14 is offed normal, and makes lower push rod 14 unsettled, and core cover 3 freely falls along the original track rising by deadweight under without outer active force, completes matched moulds and resets, and its process moves in circles like this.
