Description

Active three cold mills

The utility model relates to a kind of three cold mills, especially for producing cold rolled reinforcing steel bar with ribs, three cold mills of cold rolling hexagonal steel or round steel.

Traditional steel bar cold rolling machine is passive type three cold mills, by around the workpiece motion s that draws on the dish, drives roll rotation during work, makes deformation of rolled wire.The major defect of above-mentioned traditional reinforcing bar cold-rolling mill is: 1, during rolled piece tension dish tractive, pulling force Da Yi produces phenomenon of rupture, and security is also poor.2, produce line length, floor space is many.3, the finished product rolling pass is many, and speed is slow.As reducing rolling pass, then because of overtension, rolled piece is easy fracture more.4, the draught line during as rolled piece fracture or initial production connects in the production process, must use auxiliary equipment such as welding machine, investment big, complex process.5, can not directly use the vertical bar rolled piece, materials are single, and the adaptive surface master is narrow.

The purpose of this utility model provides a kind of easy to operate, and production safety, technology are simple, and rolling pass is few, both can rolling biscuit, again can rolling vertical bar, and active three cold mills that corollary equipment is few.

The utility model comprises support 15, be fixed on riser 4,4 ＇ of support bottom, driving shaft 1 by bearing 6,12 supporting on riser 4,4 ＇ tops, the bearing housing 16 of driving shaft 1 one ends, driving shaft 1 middle part is fixed with adjacent bevel gear 9 and bevel gear 9, is set with the collars 8 with this bevel gear rotation on the bevel gear 7.Bevel gear 7 is meshed with bevel gear 30 on the fixed axis 39 that is symmetrical set, bevel gear 9 changes 30 ＇ with bevel gear on fixed axis 39 ＇ and is meshed, be fixed with running roller ring 31 on the bevel gear 30, be fixed with collars 31 ＇ on bevel gear 30 ＇, the two axial lines of the axis of driving shaft 1 and fixed axis 30,30 ＇ intersects and is an equilateral triangle.Bearing housing 16 right-hand members can be provided with riser 24 supporting by adjusting screw rod 22 and adjusting the driving shaft axial regulating mechanism that nut 23 is formed.6,12 of riser 4,4 ＇ and bearing housings are respectively equipped with wedge radiai adjustment mechanism 5,11.

The utility model has the advantages that: 1, will be used for the bevel gear of transmission and roll ring and make up in aggregates compactly, final drive shaft and two fixed axis are arranged on three limits of equilateral triangle, the base is for connecting the final drive shaft of variable-speed motor, easy and simple to handle, only to just can directly produce with workpiece front end directly by three roll centers of artificial feeding.2, can rolling biscuit, again can rolling vertical bar, and rolled piece tension dish tractive not, can avoid the rolled piece fracture, production safety.3, rolling pass is few, and technology is simple, need not corollary equipments such as welding machine, both can reduce and produce investment, can save production site again.

Accompanying drawing 1 is the utility model example structure schematic diagram.

Among the figure: the 1-driving shaft, the 2-bearing, the 3-gland, 4,4 ＇-riser, 5-wedge radiai adjustment mechanism, the 6-bearing housing, the 7-bevel gear, the 8-collars, the 9-bevel gear, the 10-locking nut, 11-wedge radiai adjustment mechanism, the 12-bearing housing, the 13-bearing, the 14-gland, the 15-support, the 16-bearing housing, the 17-bearing, the 18-gland, 19, the 20-nut, the 21-step, 22-adjusts screw rod, the 23-nut, 24,25,25 ＇-riser, 26,26 ＇ are guiding mechanism radially, 27-semicircle briquetting, the 28-nut, the 29-bearing, 30,30 ＇-bevel gear, 31,31 ＇-roll, 32,32 ＇-riser, the 33-nut, the 34-bearing, 35, the guiding mechanism of 35 ＇-radially, the 36-nut, 37-adjusts briquetting, the 38-nut, 39,39 ＇-fixed axis.

Further describe the utility model below in conjunction with accompanying drawing.

Riser 4,4 ＇ are welded on the bottom of support 15 respectively, riser 4,4 ＇ tops are respectively according to connecting wedge radiai adjustment mechanism 5,11 and bearing
