Abstract

The utility model relates to the field of stamping dies, in particular to an inverted stamping die. The inverted stamping die comprises a die framework consisting of an upper die plate, a lower die plate, a guide post, a guide sleeve, an upper die fixing plate and a lower die fixing plate. The inverted stamping die is characterized by further comprising a material plate, a convex die fixed on the lower die fixing plate, a first concave die block and a second concave die block fixed on the upper die fixing plate, a material-crushing device, and a material-pushing device, wherein a groove matched with the convex die is formed between the first concave die block and the second concave die block; the material-crushing device penetrates through the upper die plate and is communicated with the groove; the material-pushing device is positioned between the material plate and the lower die plate. The inverted stamping die has the beneficial effects that: due to the adoption of the inverted mounting mode of the convex die and the concave die and the material-crushing device, workpieces or waste materials cannot accumulate in the groove of the concave die; therefore, the concave die is difficult to abrade; a convex die protection layer mounted on the end part of the convex die can protect the convex die; the elastic material-pushing device ensures that the die discharges materials conveniently; and the surfaces of the obtained workpieces are smooth by compacting the material plate.

Description

A kind of upside-down mounting blanking die

Technical field

The utility model relates to the diel field, relates in particular to a kind of upside-down mounting blanking die.

Background technology

Blanking die is the used mould of blank operation, can be divided into blanking die, perforating die, knife edge die, notch die, edger, parting die etc. by operation character.Traditional formal dress blanking die punch is installed on the cope match-plate pattern, and die is fixed on the lower bolster, and workpiece and waste material be (being groove) accumulated in the die hole, and easy abrasion mould cutting edge also need be processed the reverse side discharge opening of die; Secondly, impulsive force is very big during owing to stamping-out, the punch easy abrasion; In addition, the traditional rigid device for discharging is simple in structure, but can't the compact flitch so that surface of the work is smooth, be not suitable for the higher workpiece of machining accuracy.The utility model will provide the upside-down mounting blanking die of a kind of convex mold protective layer, tool elastic tripper, tool filling device.

The utility model content

The purpose of the utility model is to overcome the problems referred to above, provide a kind of punch and die not easy to wear, can be used for the smooth workpiece of finished surface, discharging convenient, discharge the upside-down mounting blanking die of waste material in the groove or workpiece easily.

For realizing above-mentioned purpose; The technical scheme that the utility model adopted is: a kind of upside-down mounting blanking die; Comprise the mould bases that cope match-plate pattern, lower bolster, guide pillar, guide pin bushing, upper mould fixed plate and counterdie fixed head are formed; It is characterized in that: also comprise material plate, be fixed in the punch of counterdie fixed head, the first die piece that is fixed in upper mould fixed plate and the second die piece, form the groove that matches with punch between the first die piece and the second die piece; Also comprise the filling device, the material-pulling device between material plate and lower bolster that run through cope match-plate pattern and be communicated with described groove.

As the further improvement to the utility model, filling device comprises knockout rod that runs through cope match-plate pattern and upper mould fixed plate and the dnockout piece that is connected in knockout rod, and the dnockout piece is communicated with described groove, and knockout rod and dnockout piece can move along groove.

As further improvement to the utility model, material-pulling device comprise the pusher spring that is fixed in lower bolster, supporter flitch push pedal, connect the push rod of pusher spring and push pedal, further, pusher spring, push pedal and push rod are a plurality of.

As the further improvement to the utility model, the punch end is provided with the punch protective layer.

The beneficial effect of the utility model is: the groove that the concavo-convex mould mounting means of flip-over type and filling device make die does not gather workpiece or waste material, thereby makes die not easy to wear; The punch protective layer of punch end can be protected punch; The elasticity material-pulling device makes this mould, and not only discharging is convenient, and makes the surface of the work of acquisition smooth through the compact flitch.

Description of drawings

Fig. 1 is the structure chart of the utility model;

Wherein, 1 cope match-plate pattern, 2 lower bolsters, 3 guide pin bushings, 4 guide pillars, 5 knockout rods; 6 dnockout pieces, 7 upper mould fixed plates, 8 counterdie fixed heads, 9 punch, 10 punch protective layers, 11 pusher springs; 12 push rods, 13 push pedals, 14 material plates, 15 first die pieces, 16 second die pieces, 17 punch inserts.

The specific embodiment

Fig. 1 is the preferred embodiment of the utility model, below in conjunction with accompanying drawing the utility model is further described: wherein, and 1 cope match-plate pattern, 2 lower bolsters, 3 guide pin bushings; 4 guide pillars, 5 knockout rods, 6 dnockout pieces, 7 upper mould fixed plates, 8 counterdie fixed heads; 9 punch, 10 punch protective layers, 11 pusher springs, 12 push rods, 13 push pedals; 14 material plates, 15 first die pieces, 16 second die pieces, 17 punch inserts.

According to Fig. 1; A kind of upside-down mounting blanking die; Comprise the mould bases that cope match-plate pattern 1, lower bolster 2, guide pillar 4, guide pin bushing 3, upper mould fixed plate 7 and counterdie fixed head 8 are formed; It is characterized in that: also comprise material plate 14, be fixed in the groove that formation matches with punch 9 between the punch 9 of counterdie fixed head 8, the first die piece 15 that is fixed in upper mould fixed plate 7 and the second die piece, 16, the first die pieces 15 and the second die piece 16; Also comprise the filling device, the material-pulling device between material plate 14 and lower bolster 2 that run through cope match-plate pattern 1 and be communicated with described groove.

Filling device comprises knockout rod 5 that runs through cope match-plate pattern 1 and upper mould fixed plate 7 and the dnockout piece 6 that is connected in knockout rod 5; Described dnockout piece 6 is communicated with described groove; Knockout rod 5 can move along groove with dnockout piece 6, and in the time of need the waste material in the groove or workpiece being got, forcing press promotes knockout rod 5 and moves down with dnockout piece 6 and make workpiece or waste material withdraw from groove; When workpiece or waste material have just withdrawed from groove, utilize compressed air with workpiece or waste material band from concavo-convex mould.
