Currently, the aforementioned annular weight-reducing grooves and weight-reducing holes are usually completed on a machine tool. Normal free forging may only be able to forge forgings with holes, and at most, the annular weight-reducing groove portion can be forged. It is not possible to machine the annular weight-reducing grooves and weight-reducing holes during forging. Utility Model Content

The upper sleeve is fitted onto the upper anvil block, and the lower sleeve is fitted onto the lower anvil block, and then fixed by the bolts on the planar grooves respectively.

[0015] Furthermore, the planar groove is provided with a horizontal elongated through hole, and the bolt is inserted into the elongated through hole.

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 3 As shown, the present invention provides an annular weight-reducing groove and a weight-reducing hole forging assembly, comprising an upper pressing component and a lower pressing component.

[0026] like Figure 4 As shown, the upper pressing component includes an upper sleeve part 1, an upper annular protrusion 2, and several lower pressing columns 3; the upper sleeve part 1 is sleeved and fixed on the upper anvil block; the upper annular protrusion 2 is located on the lower surface of the upper sleeve part 1 and is located on the same axis as the upper sleeve part 1; the thickness and width of the upper annular protrusion 2 are adapted to the annular weight reduction groove.

[0027] Several of the aforementioned pressure columns 3 are arranged in a ring array on the upper annular protrusion 2, and the length and cross-sectional diameter of the pressure columns 3 are adapted to the weight reduction holes to be processed.

[0028] like Figure 3 As shown, the lower pressing component includes a lower sleeve portion 4 and a lower annular protrusion 5; the lower sleeve portion 4 is sleeved and fixed on the lower anvil block; the lower annular protrusion 5 is located on the upper surface of the lower sleeve portion 4 and is located on the same axis as the lower sleeve portion 4; the thickness and width of the lower annular protrusion 5 are adapted to the annular weight reduction groove.

[0029] In this embodiment, the sidewalls of the upper sleeve 1 and the lower sleeve 4 are provided with a plurality of planar grooves 6 in a circular array. Each planar groove 6 is provided with a bolt 7. The upper sleeve 1 is sleeved on the upper anvil block, and the lower sleeve 4 is sleeved on the lower anvil block, and then fixed by the bolts 7 on the planar grooves 6 respectively.

[0030] Furthermore, the planar groove 6 is provided with a horizontal elongated through hole 8, and the bolt 7 is inserted into the elongated through hole 8; this arrangement facilitates the adjustment of the position of the bolt 7, and allows the upper / lower sleeve to be quickly fixed on the upper / lower anvil block.

[0031] In this embodiment, the upper sleeve 1, the upper annular protrusion 2, and the plurality of lower pressing columns 3 are integrally formed; the lower sleeve 4 and the lower annular protrusion 5 are integrally formed, which ensures the flatness of the forging surface during subsequent forging and also ensures the strength of the upper pressing component.

[0032] In this embodiment, the end of the pressing column 3 has a conical guide portion 9, which facilitates the rapid forging and forming of weight-reducing holes.

[0033] During forging, the upper and lower pressing parts are mounted on the upper and lower anvil blocks respectively. The press is started, and the upper annular protrusion 2 on the upper sleeve part 1 and the lower annular protrusion 5 on the lower sleeve part 4 forge the annular weight-reducing grooves on the upper and lower surfaces of the disc-shaped forging.
