Problems solved by technology

[0003] Due to the thinner wall thickness of the outer ring of the double-row bearing, the material flows toward the end at a faster speed during rolling. With the mandrel with restrictions at both ends, the material flows out from the gap between the mandrel and the rolling wheel profile. Burrs are formed at both ends of the forging, which affects the machining datum of the end face of the forging

Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0009] Such as figure 1 As shown, a mold for a double-row bearing outer ring includes a mandrel 20 , a rolling wheel 30 and a forging 10 installed between the 20 mandrel and the rolling wheel 30 .

[0010] During specific implementation, through the relative movement of the mandrel 20 and the rolling wheel 30, the wall of the forging 10 (double-row bearing blank) is partially rolled to flow radially and tangentially, and the forging 10 is expanded and thinned, and the material is also rolled to the Axial flow, the material flowing in the axial direction is blocked by the 30-shaped groove of the rolling wheel, and flows to the part where the diameter of the mandrel 20 is made smaller, so that the material cannot flow to the two ends of the forging 10 and form burrs, ensuring the processing standard of the end surface of the forging 10 flatness....

Abstract

The invention discloses a mold with a double row bearing outer ring. The mold comprises a mandril, an extend-rolling wheel and an extend-rolling forge piece installed between the mandril and the extend-rolling wheel. Accordingly, the flatness of the forge piece end face machining standard is guaranteed.

Description

technical field [0001] The invention relates to a mold for the outer ring of a double-row bearing. Background technique [0002] Double row bearings are bearings with two rows of rolling elements. Due to the increase in the number of columns, the radial load capacity of double row bearings increases, and at the same time it can withstand large bidirectional axial loads, so it is usually used in gear transmission, wheel bearings of heavy vehicles, hoists, cranes and other heavy machinery, It is mainly used to withstand combined radial and axial loads, mainly radial loads. [0003] Due to the thinner wall thickness of the outer ring of the double-row bearing, the material flows toward the end at a faster speed during rolling. With the mandrel with restrictions at both ends, the material flows out from the gap between the mandrel and the rolling wheel profile. Burrs are formed at both ends of the forging, which affects the machining benchmark of the end face of the forging. ...
