    • PURPOSE: A mold for manufacturing a sphere-shaped wiper shaft and a roll mill transition device having the same are provided to enhance a torsional rupture strength and bending fatigue durability and enable to environment-friendlily manufacture a sphere-shaped wiper shaft because cut chips, waste cutting oil are not generated. CONSTITUTION: A mold for manufacturing a sphere-shaped wiper shaft is composed of upper and lower molds. The lower mold comprises a lower mold base part(11), a lower base pressing part(12), and a lower base lateral surface forming protrusion(13). The upper mold comprises an upper mold base part, an upper mold pressing part, and an upper base lateral surface molding protrusion. Central parts of the lower base pressing part and upper base pressing part in one side comprises a cutting line(12a), a first convex part(12b), a convex part(12c) projected from the first convex part, and a second convex part(12d). The second convex part is extended from the convex part.
    • 目的:提供一种用于制造球形雨刷轴的模具和具有该模具的辊磨过渡装置,以提高扭转断裂强度和弯曲疲劳耐久性,并且能够环境友好地制造球形刮水器轴,因为切屑, 不产生废切削油。 构成:用于制造球形雨刷杆的模具由上下模组成。 下模具包括下模具基部(11),下基部按压部(12)和下基部侧表面形成突起(13)。 上模包括上模底部,上模压部和上基部侧面成型突起。 下侧基部按压部和上侧基部按压部的一侧的中央部由切割线(12a),第一凸部(12b),从第一凸部突出的凸部(12c)和第二凸部 (12D)。 第二凸部从凸部延伸。

    • PURPOSE: A manufacturing method of a beam for grating is provided to increase slip preventing effect of a beam which is a material composing the grating that is used as structures such as covers for drainage hole or manhole, stepladders, or covers for various facilities. CONSTITUTION: The manufacturing method of a beam for grating comprises a first process of cutting the front part of flat steel(1) having certain width and thickness manufactured in hot rolling in a ">" shaped arrow form using upper and lower knives(2,3); a second process of simultaneously forming flat steel the front part of which is cut in an arrow shape in the first process into an I beam(H) using rotating upper and lower rollers(4,5), and forming a protrusion(6) having a certain height on one side cross section of the width direction of the I beam by forming the I beam using upper and lower rollers(4,5) on the surface of which is formed in a round shape so that a round part(7) is formed on a region where the protrusion(6) is formed; and a third process of manufacturing the beam for grating by passing a material to be processed which is formed into an I beam, and on one side cross section of the width direction of which the protrusion(6) having a certain height is formed in the second process between impression pressure forming rolls(8,9) which are horizontally rotated, wherein grooves(8a,9a) into which the material to be processed is inserted are formed in a deep depth on the impression pressure forming rolls(8,9) so that the impression pressure forming rolls(8,9) stably grip the grooves(8a,9a), and one side cross section of the material to be processed is formed in a plane shape while the protrusion(6) on the other side of the material to be processed is formed in an irregular shape.
