Bar after-rolling guiding device

Abstract

The invention relates to the field of steel rolling equipment, in particular to a bar after-rolling guiding device. The bar after-rolling guiding device comprises a supporting seat, a plurality of positioning plates and a guiding pipe; the positioning plates are evenly and fixedly mounted on the supporting seat, the guiding pipe comprises an inlet guiding pipe, a plurality of intermediate guidingpipes and an outlet guiding pipe, the inlet guiding pipe, the intermediate guiding pipes and the outlet guiding pipe each include a front-end guiding pipe and a positioning guiding pipe, and the outerdiameter of each front-end guiding pipe is greater than that of each positioning guiding pipe; and a positioning hole is formed in the corresponding position in each positioning plate, the positioning guiding pipes penetrate through the positioning holes, the upper parts of positioning guiding pipes are fixedly connected with the positioning plates through bolts, a guiding hole is formed in eachof the front-end guiding pipes and the positioning guiding pipe, the guiding hole in each front-end guiding pipe is in a horn shape, the aperture of the guiding hole in each front-end guiding pipe isthe same as that of the guiding hole in each positioning guiding pipe. The bar after-rolling guiding device is simple in structure, low in cost, high in efficiency and fast and convenient to replace and overhaul.

Description

technical field [0001] The invention relates to the field of steel rolling equipment, in particular to a bar rolling guide device. Background technique [0002] Split rolling is a high-efficiency and low-energy-consumption technology for modern small bar production. It is generally used in the production of small bars. After the bar is split and rolled, the finished product needs to be introduced into the same guide groove and then smoothly enters the flying shear. The guide devices in the prior art all adopt the multi-wire conduit integrated with the support, and the conduit is a long tube arranged along the extension direction of the support. Such an arrangement will easily cause the multi-wire finished product to twist or flick, causing the finished product The surface quality and production efficiency have a considerable adverse effect. When winding or steel blocking occurs, the guide device needs to be disassembled or replaced as a whole. The processing efficiency is re...

Problems solved by technology

The guide devices in the prior art all adopt the multi-wire conduit integrated with the support, and the conduit is a long tube arranged along the extension direction of the support. Such an arrangement will easily cause the multi-wire finished product to twist or flick, causing the finished product The surface quality and production efficiency have a considerable adverse effect. When winding or steel blocking occurs, the guide device needs to be disassembled or replaced as a whole. The processing efficiency is relatively low and the cost is high. Moreover, the design of the conduit is relatively clumsy, the length is too long, and the rod The temperature of the finished material after rolling still reaches about 900°C, and the conduit is easily deformed under the alternating action of high temperature and conduit cooling water, which is not conducive to the surface quality of the finished product and the improvement of production efficiency
