Description

Quick feeding device between cross wedge rolling mills

Technical Field

The invention relates to the technical field of cross wedge rolling equipment, in particular to a quick feeding device between cross wedge rolling mills

Background

The cross wedge rolling is an advanced technology for forming shaft parts, and has the characteristics of energy conservation, material saving, high efficiency, environmental protection, low noise, long service life of a die and the like. However, because of radial compression and axial extension in the cross wedge rolling forming process, the surface of the metal material always flows faster than the center of the metal material, so that concave surfaces, looseness or holes are formed at two ends of a rolled piece, and the shaft piece is scrapped, therefore, enough stub bars must be left at two ends of the cross wedge rolling piece, and the stub bars are cut off after forming and thrown away as waste materials. The bigger the stub bar is, the more the waste material is, and the stub bar is too small, which can cause concave centers and looseness at two ends of the product and form waste products. Therefore, the important factor for improving the material utilization rate of the cross wedge rolled piece is to reduce the stub bars at the two ends of the rolled piece. In order to solve the above problems, a special mold may be designed on the first rolling mill to roll the heated bar and to roll both ends of the bar into a desired fixed shape. The bar with fixed shapes at both ends is then quickly transferred from the first mill to the second mill with a quick transfer device where final shaping is achieved.
