Abstract

The utility model provides a drawing machine mechanism, which comprises a punch, a redrawing sleeve, a cup conveying passage, a die area, a stripping rubber ring and a bottom die. The die area is provided with a redrawing ring, a first die, a second die and a third die; the outer diameters of the first die, the second die and the third die are gradually decreased; the punch has a shape matching with that of the bottom die of a tank; the tank enters the die area from the cup conveying passage; the redrawing sleeve tightly presses the tank on the redrawing ring; the punch advances to draw the tank formed by the aid of the redrawing ring; then the tank is drawn, thinned and formed by the aid of the first die, the second die and the third die which have gradually decreased outer diameters; and finally the tank is punched to the position of the bottom die so that the bottom of the tank is formed and the punch returns to pass through a return position. Simultaneously, compressed air in a plunger blows out to strip the tank from the punch, so that drawing and bottom forming procedures are completed. Compared with an existing product, the drawing machine mechanism has the advantages that drawing finished product rate is high, and production cost is reduced as a bottom forming mechanism is arranged.

Description

A kind of stretching-machine mechanism

Affiliated technical field

The utility model relates to a kind of can making machinery, especially a kind of stretching-machine mechanism in the can making machinery.

Background technology

Stretching-machine in the system jar acts on the jar that cup press is rushed out and is stretched to required suitable height, and bottom moulding with jar, common stretching-machine drawing effect is undesirable, what perhaps have is not provided with jar bottom shaping mechanism, make the moulding of jar bottom need set up the bottom make-up machine in addition, increased production cost.

The utility model content

For addressing the above problem, the utility model provides a kind of stretching-machine mechanism, comprise drift, again expanding sleeve, cup feed track, mould district, peel off cushion rubber, bed die.

Described mould district is provided with stretch ring, a mould, two moulds, three moulds again, and the external diameter of a mould, two moulds, three moulds is descending.

Described drift is provided with the shape of coincideing with the jar bed die.

Its working method is: jar enters the mould district by the cup feed track, expanding sleeve is pressed on jar again on the stretch ring again, drift advances jar is stretched by stretch ring formation again, after through the descending mould of external diameter, two moulds, three mould tension-thining moldings, backlash to bed die place makes jar bottom moulding, the drift backhaul, simultaneously the jumper bar compressed air blows out jar is peeled off from drift through return of goods place, finishes stretching, bottom molding procedure.

This is practical simple in structure, relative existing product, and the yield rate height of stretching, and be provided with the bottom shaping mechanism simultaneously, reduced production cost.

The specific embodiment

Below, the utility model is described in further detail with reference to accompanying drawing.

Ask for an interview Fig. 1, Fig. 2, a kind of stretching-machine mechanism, comprise drift A, again expanding sleeve B, cup feed track C, mould district D, peel off cushion rubber E, bed die F.

Described mould district D is provided with stretch ring D1, a mould D2, two mould D3, three mould D4 again, and the external diameter of a mould D2, two mould D3, three mould D4 is descending.

Described drift A is provided with the shape of coincideing with bed die F.

Its working method is: jar G enters mould district D by cup feed track C, expanding sleeve B is pressed on jar G again on the stretch ring D1 again, drift A advances jar G is stretched by stretch ring D1 formation 1 again, after through the descending mould D2 of external diameter, two mould D3, three mould D4 tension-thining

moldings

2,3,4, backlash to bed die F place makes jar G bottom moulding 5, drift A backhaul, through return of goods place (not shown) simultaneously jumper bar A compressed air (not shown) blow out jar G peeled off from drift A, finish stretching, bottom molding procedure.

Claims
