S5, take upper cavity die, lower cavity die and die sleeve apart, take out rivet.
Further, in described step S1, described silk material cuts off after straightening on lathe again.
Further, described upper cavity die and described die sleeve interference fits, described lower cavity die and described die sleeve interference fits.
Further, described punching and glove hole are separately positioned on the middle position of described upper cavity die and described lower cavity die, and the diameter of described punching is greater than the diameter of described glove hole.
Beneficial effect of the present invention is: by traditional Integral die is divided into upper cavity die and lower cavity die, recycling die sleeve is fixed, by drift, the rivet be placed in the glove hole of lower cavity die carry out upsetting system, which obviate in upsetting process that the part that causes and mould are scrapped because the distortion of rivet elongated portion, improve the passing rate of processing of part.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the mould of the elongated brass rivet of manufacture of the present invention;
Fig. 2 is the method flow diagram of the method manufacturing elongated brass rivet.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Consult shown in Fig. 1, the mould of the elongated brass rivet of manufacture of the present invention, comprise base 1, it also comprises upper cavity die 2, lower cavity die 3, die sleeve 4 and drift 5, and lower cavity die 3 is fixed on the upper surface of base 1, and upper cavity die 2 and lower cavity die 3 are interconnected by die sleeve 4, a punching 6 is provided with in upper cavity die 2, be provided with a glove hole 7 in lower cavity die 3, the position of punching 6 is corresponding with the position of glove hole 7, and drift 5 is located in punching 6.The present invention is by being divided into upper cavity die 2 and lower cavity die 3 by traditional Integral die, recycling die sleeve 4 is fixed, by drift 5, the rivet be placed in the glove hole 7 of lower cavity die 3 carry out upsetting system, which obviate in upsetting process that the part that causes and mould are scrapped because the distortion of rivet elongated portion, improve the passing rate of processing of part.
Concrete, conveniently at assembling and location upper cavity die 2, the top of die sleeve 4 is provided with a stepped hole 8, and upper cavity die 2 is fastened in stepped hole 8.And the upper surface of die sleeve 4 and the upper surface level mutually of upper cavity die 2, can see whether die sleeve 4 and upper cavity die 2 preserve level so intuitively, avoid assembling phenomenon not in place and occur.
