Apparatus for manufacturing tube yoke

Abstract

The present invention relates to an apparatus for manufacturing a tube yoke, capable of rapidly manufacturing a tube yoke provided with a spline on a tube part through a forging step while preventingdistortion involving a twisted shape of the spline. To this end, the apparatus for manufacturing the tube yoke, according to the present invention, comprises a plurality of molds for molding the tubeyoke formed so as to mold the tube yoke by injecting a material into dies and pressing with a punch to form the tube yoke comprising the tube part and a yoke part, wherein the apparatus for manufacturing the tube yoke further comprises a spline forging mold equipped with a mold pin, which is provided with a spline part on the outer circumferential surface thereof, for forming the spline on the inside of the tube part by being inserted into the tube part.

Description

technical field [0001] The present invention relates to a pipe yoke manufacturing apparatus, and more particularly, to a pipe yoke manufacturing apparatus in which a pipe yoke having a spline in a pipe portion can be rapidly manufactured by a forging process , and can prevent the shape of the spline from twisting. Background technique [0002] A typical yoke is configured for use when the driven shaft is not collinear with the main shaft of rotation but is arranged obliquely at a predetermined angle or with respect to the main shaft (as in the case of a driving vehicle, a propulsion shaft for transmitting engine power, etc. etc.) when collinearly arranged, the power of the main drive shaft is smoothly transmitted to the driven shaft. [0003] figure 1 is a perspective view of a typical pipe yoke comprising a yoke 2 and a shaft 3 coupled to the lower part of the yoke 2 . [0004] In the case of a typical pipe yoke, the yoke 2 and the shaft 3 are manufactured separately, an...

Problems solved by technology

[0007] However, in the case of a tube yoke in which the yoke and the shaft are integrally formed, it is difficult to form a spline in the inner surface of the tube yoke, so there is a limitation that additional processes such as straightening must be performed after the spline is formed

[0008] In addition, as described above, due to the difficulty in forming the splines, there are cases where a tube yoke in which the yoke and the shaft are integrally formed is manufactured by a forging process, and the spline forming is performed by a separate machining process, But this leads to the limitation that not only the manufacturing time transition increases but also the manufacturing cost
