The specific embodiment

Below in conjunction with the drawings and specific embodiments, utility model is described in further detail.

Consult shown in Fig. 1, a kind of U iron extrusion die that utility model provides, comprise upper mould device and lower mold apparatus, wherein, upper mould device comprises upper base plate 2, is installed on the upper die plate 1 on upper base plate 2, be located at upper base plate 2 lower ends and be positioned at the patrix fixed cover 3 in upper die plate 1 outside, be located at backing plate 4 in the patrix of upper die plate 1 lower end, be installed on the upper molded plate 5 of patrix fixed cover 3 lower ends by an axis of guide, and be installed on the punch 15 of the lower end of backing plate 4 in patrix; And lower mold apparatus comprises counterdie seat board 13, be installed in the counterdie on counterdie seat board 13 and pad 12, be installed on and in counterdie, pad the counterdie 8 on 12, be installed on the die 16 in counterdie 8, be installed in counterdie, pad 12 and counterdie seat board 13 in and the post rod mechanism that is communicated with die 16, and be installed on counterdie seat board 13 for regulating die 16 horizontal displacements so that the governor motion of the axis conllinear of die 16 axis and punch 15; And the diameter of punch 15 is less than the diameter of die 16.

Concrete, governor motion comprises the adjustment ring 10 being installed on counterdie seat board 13, and adjustment ring 10 is arranged in the outside of counterdie pad 12 and counterdie 8, be located at the adjustment block 19 between counterdie 8 and adjustment ring 10, and adjustment block 19 is arranged in the upper end of mould pad 12, and be installed on the circumferencial direction of adjustment ring 10 and the multiple adjustment screws 18 corresponding with adjustment block 19; Adjust screw 18 by adjusting and make adjustment block 19 push the outside of counterdie 8, that is: the horizontal displacement of the adjustable die 16 that is positioned at counterdie 8, can make the axis of die 16 and the axis conllinear of punch 15.

Concrete, can also counterdie gland 6 be also installed in the upper outside of counterdie 8, counterdie gland 6 is also fixedly connected with adjustment ring 10; The installed surface of the top of counterdie 8 and counterdie gland 6 is cascaded surface, can be used for preventing that counterdie 8 is at axial float.

Above-mentioned post rod mechanism comprises is located at the interior cushion block 11 moving up and down of upper base plate 12, through counterdie seat board 13 push rod 14 that is connected with the bottom of cushion block 11, and be installed on the knock-pin 9 of the upper end of cushion block 11, and knock-pin 9 is communicated with die 16.And be provided with on the top of counterdie 8 and blow material pipe 17, blow material pipe 17 and be also connected with an air compressor (not shown).After workpiece 7 extrusion moldings, can the U iron after being shaped be ejected to die 16 by post rod mechanism, and the U iron that ejects die 16 can blow away by blowing material pipe 17 compressed air that blow out, and completes discharging.

1 to Fig. 3 the operation principle of U iron extrusion die of the present utility model is described further by reference to the accompanying drawings more below:

As shown in Figure 1, in use, first by regulating the adjustment screw 18 of above-mentioned governor motion to make the axis of die 16 and the axis conllinear of punch 15, and flat workpiece 7 is placed in die 16.

As shown in Figure 2, starting upper mould device makes punch 15 exert pressure to workpiece 7, and, because the diameter of punch 15 is the diameters that are less than die 16, there is gap between the two, and then the metal of workpiece 7 just along on the gap between punch 15 and die 16 flow, thereby make required drag cup part, i.e. T iron product.

As shown in Figure 3, by upper mould device, punch 15 is upwards exited and leave die 16, push rod 14 up pushes cushion block 11 and knock-pin 9, can make the T iron product processing exit die 16, and then utilize to blow and expect that pipe 17 compressed air that blow out blow away, and can complete the making of T iron product.

Although described by reference to the accompanying drawings the embodiment of utility model; but the patent owner can make various distortion or modification within the scope of the appended claims; as long as be no more than the described protection domain of the claim of utility model, all should be within the protection domain of utility model.
