Abstract

The invention provides a combined round material straightening device. The device comprises a rack, wherein the rack is of a frame structure, and the rack is directly or indirectly provided with a first upper transmission roller and a first lower transmission roller which are arranged in an up-down corresponding mode, a second upper transmission roller and a second lower transmission roller which are arranged in an up-down corresponding mode, a third upper transmission roller and a third lower transmission roller which are arranged in an up-down corresponding mode, and an upper staggered roller, a first lower staggered roller and a second lower staggered roller which are arranged in an up-down staggered mode, wherein the upper staggered roller is located between the first lower staggered roller and the second lower staggered roller in a horizontal direction, and the first upper transmission roller, the first lower transmission roller, the second upper transmission roller, the second lower transmission roller, the third upper transmission roller, the third lower transmission roller, the upper staggered roller, the first lower staggered roller and the second lower staggered roller are distributed in a straightening direction and are all in a hyperbolic roller type. The invention further provides a combined type round material straightening method, which is implemented by adopting the combined type round material straightening device.

Description

technical field [0001] The invention belongs to the technical field of round material straightening, and in particular relates to a combined round material straightening device and a straightening method thereof. Background technique [0002] Round material straightening generally adopts one of two straightening methods: double-roll straightening or staggered-roll straightening. The advantage of the double-roller straightening is that the main drive of the entrance double-roller is especially suitable for biting and straightening the round material with large bending, and its straightening accuracy is less than 1‰. The staggered roller straightening is especially suitable for straightening the local small bending of the round material, and the accuracy can reach 0.8‰ after one straightening, but the bending degree of the incoming material is required to be relatively good, otherwise it is difficult to meet the predetermined accuracy requirements.
