Abstract
The utility model relates to a mould for forging small and medium-sized gear single-sided pressure wheel spokes, which is mainly used for forging the small and the medium-sized gear single-sided pressure wheel spokes. The mould comprises an external mould (1), an internal mould (2), a punch head II (3) and a punch head I (4). The external mould (1) is in the shape of a cylinder (1); the internal mould (2) is embedded in the lower part of the external mould (1); a lug boss (2.1) is arranged in the middle of the internal mould (2); a stepped through hole (2.2) is formed at the center of the lug boss (2.1); the punch head II (3) is arranged inside the stepped through hole (2.2); the punch head I (4) is arranged above the stepped through hole (2.2). The lug boss is fabricated during the design of the mould of the utility mould, and the spoke is forged and fabricated during the forging, so that on the one hand, the blanking weight of the small and the medium-sized gear forgings is reduced and the cost is saved, and on the other hand, the middle part of the spoke tries best to keep the fiber uninterrupted during the machining, and the strength of the forgings is enhanced.
Description
(1) technical field
The utility model relates to a kind of forging mold, is specifically related to a kind of middle-size and small-size gear single face pinch roller spoke forging mold.Be mainly used in and forge middle-size and small-size gear single face pinch roller spoke.Belong to forging equipment attachment technique field.
(2) background technology
Before the utility model is made, in the middle of the present middle-size and small-size gear (as Fig. 1) the thin part when forging all with the clout filling, after moulding, make with machine-tooled method.This forging mode has increased the cutting stock weight of middle-size and small-size gear forgings, has increased cost, also can make spoke mid portion fiber when machined produce fracture, has reduced the intensity of forging.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of middle-size and small-size gear single face pinch roller spoke forging mold that can reduce the forging cutting stock weight, increase forging intensity is provided.
The purpose of this utility model is achieved in that a kind of middle-size and small-size gear single face pinch roller spoke forging mold, form by external mold, internal mold, drift II and drift I, described external mold is cylindric, described internal mold is embedded at bottom in the external mold, be provided with boss in the middle of the described internal mold, the boss center is provided with step through-hole, and drift II is arranged in the described step through-hole, and drift I is arranged at described step through-hole top.
The utility model is made boss when designing mould, during forging spoke is forged out, so both alleviated the cutting stock weight of middle-size and small-size gear forgings, saved cost, can also make the spoke mid portion when machined, keep not rupturing of fiber as far as possible, increase the intensity of forging.
(4) description of drawings
The middle-size and small-size gear forgings figure that Fig. 1 relates to for the utility model.
Fig. 2 is the general structure schematic diagram of the middle-size and small-size gear single face of the utility model pinch roller spoke forging mold.
Among the figure: external mold 1, internal mold 2, drift II 3, drift I 4, boss 2.1, step through-hole 2.2.
(5) specific embodiment
Referring to Fig. 2, the middle-size and small-size gear single face pinch roller spoke forging mold that the utility model relates to mainly is made up of external mold 1, internal mold 2, drift II 3 and drift I 4.Described external mold 1 is cylindric, described internal mold 2 is embedded at bottom in the external mold 1, is provided with boss 2.1 in the middle of the described internal mold 2, and boss 2.1 centers are provided with step through-hole 2.2, drift II 3 is arranged in the described step through-hole 2.2, and drift I 4 is arranged at described step through-hole 2.2 tops.
Claims (1)
1, a kind of middle-size and small-size gear single face pinch roller spoke forging mold, it is characterized in that described forging mold is made up of external mold (1), internal mold (2), drift II (3) and drift I (4), described external mold (1) is cylindric, described internal mold (2) is embedded at the interior bottom of external mold (1), be provided with boss (2.1) in the middle of the described internal mold (2), boss (2.1) center is provided with step through-hole (2.2), drift II (3) is arranged in the described step through-hole (2.2), and drift I (4) is arranged at described step through-hole (2.2) top.
