The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be described in further detail.
Consult shown in Fig. 1, a kind of U iron extrusion die that invention 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, by an axis of guide, be installed on the upper molded plate 5 of patrix fixed cover 3 lower ends, and the punch 15 that is installed on 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 a plurality of adjustment screws 18 corresponding with adjustment block 19; By adjusting, adjust the outside that screw 18 makes adjustment block 19 extruding counterdies 8, that is: the adjustable horizontal displacement that is positioned at the die 16 of 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, the push rod 14 that passes counterdie seat board 13 and be connected with the bottom of cushion block 11, and the knock-pin 9 that is installed on the upper end of cushion block 11, and knock-pin 9 is communicated with die 16.And on the top of counterdie 8, be provided with 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 invention 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 is just along flowing on the gap between punch 15 and die 16, 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 working of an invention mode; 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 invention, all should be within the protection domain of invention.
