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, the lower die structure of a kind of U iron extrusion die that invention provides, comprise 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 and pad on 12 and the post rod mechanism being communicated with die 16, and be installed on counterdie seat board 13 for regulating the governor motion of die 16 horizontal displacements.
Concrete, governor motion comprises the adjustment ring 10 that is installed on counterdie seat board 13 and is positioned at counterdie 8 outsides, 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 counterdie 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 punch axis conllinear of patrix, solve the mesopore of part and the problem of cylindrical decentraction, and then improved the dimensional accuracy of product.
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.
Consult shown in Fig. 2, U iron extrusion die for lower die structure composition of the present invention, mainly that upper mould device is installed on lower die structure, this upper mould device comprises upper base plate 2, be 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 the 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.
The operation principle of 2 to Fig. 4 U iron extrusion dies that lower die structure of the present invention is formed is described further by reference to the accompanying drawings more below:
As shown in Figure 2, in use, first by regulating the adjustment screw 18 of above-mentioned governor motion to make the axis of die 16 of lower die structure and the axis conllinear of the punch 15 of patrix upper limbs, and flat workpiece 7 is placed in die 16.
As shown in Figure 3, 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 4, 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.
Known by description above, this bright one side is provided with for regulating the governor motion of die 16 horizontal displacements in lower die structure, in mould extrusion process, can make by governor motion punch 15 concentric locatings of die 16 and upper mould device, the mesopore of part and the problem of cylindrical decentraction have been solved, improved the dimensional accuracy of product, and according to the theory of plastic deformation of metal material, adopt mould U iron to be pushed to production, the raw-material waste of larger minimizing.
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.
