Abstract
The utility model belongs to a high-performance cold rolling facility for building steel bars, mainly composed of a machine frame, three rollers and a transmission mechanism, wherein, the rollers are all arranged on the machine frame through respective middle axles; included angles of adjacent rollers are 120 DEG; the three rollers are correlated through the transmission mechanism; a roll separating mechanism is arranged on the machine frame; the centre axle of one of the rollers is connected with a power output device. The utility model has the advantages that the index if each mechanical property of products is improved, a plurality of rolling machines can easily form a continuous rolling system, the service lives of the rollers are prolonged, the consumption is reduced, the service efficiency of the device is improved, and the rapid and convenient integral roller-changing is achieved.
Description
The utility model belongs to a kind of cold-rolling equipment of high-effect building bar.
At present, the cold drawn method of rolling of the general employing of the production of three rib spirals, its three rolls are passive rotation, and reinforcing bar vertically need bear huge pulling force in pulling process, make on the raw material the existing defective not only can not pressing, and very easily expansion, to making the cold drawn mechanical performance index (mainly being percentage elongation) that rolls three rib steel muscle often not reach national standard.Domestic also once the someone develop the equipment that adopts pure rolling mill practice, but because its roll is in cantilever position, rigidity is bad, influences product quality.
The purpose of this utility model is to provide a kind of cold-rolling equipment that overcomes three rib spirals of above-mentioned disadvantage.
The utility model is realized by following scheme: it is mainly by frame, three rolls and transmission mechanism are formed, it is characterized in that roll all the axis by separately be arranged on the frame, the adjacent rollers angle is 120 °, roll-separating mechanism is set on frame, three rolls are interrelated by transmission mechanism, the axis of one of them roll links to each other with motive power outputting apparatus, transmission mechanism is made up of four intermeshing bevel gears that are arranged on each axis, roll-separating mechanism is by adjusting nut, last skewback, following skewback, clutch and sprocket wheel constitute, it is relative with following skewback inclined-plane wherein to go up skewback, connect by the roll support frame, roll shaft is connected with the roll support frame by bearing, three sprocket wheels link to each other by chain, and sprocket wheel links by clutch with the adjustment nut.
Advantage of the present utility model is:
1, rolled piece is in the three dimension stress stress state in the operation of rolling, so the fine crack in the raw material can be able to pressing, density is improved, thereby has improved every mechanical performance index of product.For LL
800, δ 0.2＞640MPa, δ
b＞800MPa, δ
100＞4%.
2, roll mandrel is the simply supported beam form of double base, thus good rigidly, thus guaranteed the size of product and the precision of geometry.
3, can easily form continuous-rolling system by many rolling mills, each milling train is to drive separately.
4, the design of this machine has radially guiding mechanism of roll gap, to adapt to the requirement of roll wear or replacing production kind, improves roll campaign, reduces consuming, and has improved the service efficiency of equipment, has saved service working time.
5, adopted assembly roller, the structure of split bearing seat has realized whole roll change, and is rapidly convenient.
Accompanying drawing 1 is the front view of cold-rolling mill;
Accompanying drawing 2 is the left view of cold-rolling mill.
Below in conjunction with accompanying drawing the utility model is described further:
As Fig. 1, shown in 2, cold-rolling mill is by frame 1, three rolls 5, roll-separating mechanism and transmission mechanism are formed, roll 5 is arranged on the frame 1 by axis 2, making adjacent roll 5 angles is 120 °, three rolls are interrelated by transmission mechanism, its transmission mechanism is made up of four intermeshing bevel gears 3 that are arranged on each axis 2, roll-separating mechanism is by adjusting nut 13, last skewback 10, following skewback 11, clutch 14 and sprocket wheel 15 constitute, it is relative with following skewback 11 inclined-planes wherein to go up skewback 10, connect by roll support frame 4, roll shaft 5 is connected with roll support frame 4 by bearing 6, and three sprocket wheels 15 link to each other by chain.Sprocket wheel 15 links by clutch 14 with adjusting nut 13, realizes concentrating and adjusts or adjust separately.
During cold-rolling mill work, at first drive an axis 2 by motive power outputting apparatus and rotate, two pairs of bevel gears that are meshed 3 rotate each axis 2 synchronously, and three rolls 5 are rotated, and reinforcing bar is rolled by three rolls, 5 formed passes.
When needing to adjust roll gap when the reinforcing bar of rolling different size as required, at first regulate and adjust nut 13, adjust nut 13 and make skewback 10 move left and right by screw rod, then descend skewback 11 along with radially moving up and down along roll 5, roll support frame 4 also moves up and down thereupon, move thereby drive bearing 6 and axis 2, make three rolls, 5 formed passes obtain adjusting.
