Referring to fig. 10 and 11, the lower expansion core rod 31 and the upper expansion core rod 41 are designed to be rectangular, and the thickness L1 is L2, so that the dimensional stability of the press inner die 21 and the shaping inner die 22 after expansion is always ensured during the movement from bottom to top; in order to ensure the strength of the expanding mandrel, the width L3 of the lower expanding mandrel 31 and the upper expanding mandrel 41 is as wide as possible, the specific size is determined according to the shape of the product, and the minimum width L3 is more than or equal to 1/2L4, wherein L4 is the width of the profiling inner die 21 and the shaping inner die 22 and can also be considered as the width of the thin-walled product 1; the sizing and profiling dimensions can be finely adjusted by adjusting the thickness L5 of the blade 53.

The use method of the thin-wall product profiling and shaping integrated machining tool provided by the embodiment is as follows:

the upper die 4 is lifted upwards through the equipment sliding block, the pressing block 43 is separated from the compression type inner die 21 and the shaping inner die 22, the lower expansion core rod 31 and the upper expansion core rod 41 are respectively positioned below and above the compression type inner die 21 and the shaping inner die 22 along the vertical direction, the thin-walled product 1 is sleeved on the compression type inner die 21 and the shaping inner die 22 and abuts against the lower part of the thin-walled product 1 through the supporting block 28, the driving connecting shaft 36 is lifted to drive the piston plate 35 to slide upwards between the vertical plates 34, and therefore the lower expansion core rod 31 is driven to lift upwards and be inserted into the compression type inner die 21 and the shaping inner die 22 along the vertical direction, and the compression type inner die 21 and the shaping inner die 22; then the upper die 4 is controlled to move downwards by the device sliding block, the pressing block 43 presses the upper part of the thin-wall product 1 under the action of the material pressing spring 45, the upper expansion mandrel 41 further expands the compression inner die 21 and the shaping inner die 22, the slotting tool 53 is contacted with the sliding block 52, the sliding block 52 is gradually driven to move along the horizontal direction to extrude the thin-wall product 1, the compression is completed through the matching of the convex block 26 and the groove 25, the shaping is realized through the matching of the shaping outer die 24 and the shaping inner die 22, after the supporting plate 58 is abutted to the fixed plate 51, the upper die 4 moves upwards again to leave the compression inner die 21 and the shaping inner die 22, the sliding block 52 is pulled back by the connecting shaft 54 under the action of the return spring 55, the compression outer die 23 and the shaping outer die 24 leave the compression inner die 21 and the shaping inner die 22, the pressing block 43 is pulled upwards to leave the thin-wall compression product 1 under the action of the limiting, and taking down the processed thin-wall product 1.

The profiling and shaping work of the thin-wall product 1 is completed completely by the linear motion of the lower die 3 and the upper die 4 in the working process, the use is convenient, and the working efficiency is improved.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
