Description
Affiliated technical field
The utility model relates to a kind of metal wire rod tandem mill.
Background technology
The metal wire rod tandem mill is the equipment of extensive use in the metal manufacture field, and the at present domestic tandem mill that generally uses is made up of single double-roller type frame or three-roller type frame.As main equipment, its investment is big, floor space is big, and energy consumption is big, and lumber recovery and mill bar quality are undesirable.Though domestic in recent years tandem mill improves to some extent, adopted double-roller type and Y type three-roller type frame, vertical and level, underdrive and last transmission replace the tandem rolling mechanism of arrangement combinations; But its frame quantity is 14 secondary or 12 pairs, wherein the double-roller type frame is 2 secondary or 4 pairs, Y type three-roller type frame is 12 secondary or 8 pairs, though shortened the unit total length, floor space reduces to some extent, wire quality is increased, manufacturing cost descends to some extent, but compression ratio is still not high enough, to advance the ingot area little, and the quality of tandem rolling product is still waiting to improve.
Summary of the invention
The purpose of this utility model just provides a kind of metal wire rod tandem mill, and this kind tandem mill compression ratio is big, advance that the ingot area is big, rolling power is strong, rolling accuracy is high, effective, low cost of manufacture, floor space is little, comprehensive mechanical performance good.
The utility model solves its technical problem, and the technical scheme that is adopted is: a kind of metal wire rod tandem mill, contain motor, active drawing-in device, uni-drive gear box and base and tandem rolling mechanism.This tandem rolling mechanism has 12 secondary or 14 secondary frames, and from active drawing-in device one side: the 1st～No. 6 six secondary frame is the double-roller type frame; All the other each frames are Y type three-roller type frame.
Compared with prior art, the beneficial effects of the utility model are: constitute tandem rolling mechanism owing to adopted two rollers and three-roll rack to mix, and the double-roller type frame of front end increases to 6 pairs by 2 pairs or 4 pairs, so the initial stage that increased is rolled the pressurized of metal, thereby compression ratio increases substantially, and can make to be rolled the sectional area of part before advancing to roll from 1600 traditional～2100mm
2Bring up to 2400～3500mm
2, thereby rolling power is stronger; And three-roller type frame thereafter reduces to 6 pairs (when total frame is 12 pairs) or 8 pairs (when total frame is 14 pairs), make structure more reasonable, transmission efficiency improves, and mechanical performance is better, has improved the heart portion structure that is rolled part, the microcosmic slight crack and the bubble of wire rod have been overcome, compression ratio is bigger, is out of shape more fully, and metal structure is tightr, rolling accuracy height, effective, wire broken rate reduces greatly in the reprocessing wire-drawing process afterwards.
The the 1st, 3, No. 5 frame in the 1st～No. 6 six above-mentioned secondary frame is vertical roller double-roller type frame, and the 2nd, 4, No. 6 frame is horizontal roller double-roller type frame.
The double-roller type frame adopts vertical, horizontal mode interlaced arrangement, can be rolling to all directions enforcement that is rolled part, help improving mechanical performance of products.
When above-mentioned tandem rolling mechanism is 12 secondary frames, the Y type three-roller type frame that the Y type three-roller type frame that the 7th, 9, No. 11 frame in back six width of cloth frames is underdrive, the 8th, 10, No. 12 frame are last transmission.
When above-mentioned tandem rolling mechanism is 14 secondary frames, the Y type three-roller type frame that the Y type three-roller type frame that the 7th, 9,11, No. 13 frame in back eight width of cloth frame is underdrive, the 8th, 10,12, No. 14 frame are last transmission.
