Abstract
The utility model relates to a driving type three-roll three-surface rolling machine. Three shafts which are formed angles of 60 DEG with each other are arranged on a machine frame; a round sheet-shaped roller is arranged on each of the three shafts; the three rollers are formed into an angle which is of 120 DEG mutually; the circle of each of the roller is provided with a concave curved groove-shaped working face; a falcate ribbed hole is arranged on the working face; a bevel gear is respectively arranged on the two sides of each of the rollers of a shaft; one end of each of the other two shafts is respectively provided with a bevel gear which is engaged with the two bevel gears on the shaft; the rolling machine can be used for rolling straight ribbed reinforced bars, particularly for the combination with hot rolling machine group; when the temperature of round steels after hot rolling reduces to 400 centigrade degrees to 450 centigrade degrees, straight ribbed reinforced bars with good mechanical property can be continuously rolled.
Description
The utility model relates to a kind of milling train, three milling trains of particularly a kind of active three rollers.
In the prior art, the milling train of rolling cold rolled reinforcing steel bar with ribs for building all is three milling trains of slave mode three rollers, three axles that 60 ° of angles of mutual one-tenth are arranged on the frame of this milling train, a garden sheet shape roll is arranged respectively on three axles, garden sheet shape roll concave arc ditch shape working face arranged in garden week, falcate rib hole is arranged on the working face, three rolls become hexagonal angle mutually, three working faces surround and roll the hole, during work, the spooler of milling train afterbody twines rolling intact Ribbed Bar, produces tractive force, make the roll hole of raw steel, rolled into Ribbed Bar by milling train.The Ribbed Bar product of this mill milling is the wire rod form, needs alignment in use, for
Ribbed Bar below 6 can be with stretching method alignment, but for
Ribbed Bar more than 6 need be used the straightener alignment, and with the straightener alignment time, the rib that can destroy Ribbed Bar pushes up and the influence use; In addition for
Ribbed Bar more than 10 is difficult to use the slave mode mill milling.
The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes three milling trains of active three rollers of a kind of cold rolling vertical bar Ribbed Bar that can rolling all size.
The utility model is realized with the following method.
Three milling trains of active three rollers have three garden sheet shape rolls that are mutually hexagonal angle, three rolls are being mutually on the frame on three axles at 60 ° of angles respectively, in three axles, one is driving shaft, two is countershaft in addition, and on driving shaft, respectively there is a bevel gear roll both sides, an end of two countershafts in addition, respectively have one respectively with driving shaft on two bevel gears that bevel gear is meshed.When rotating with the power drive driving shaft, three rolls can rotate synchronously, be rolling Ribbed Bar, concave arc ditch shape working face is arranged in roll garden week, falcate rib hole is arranged on the working face, three working faces surround garden shape and roll the hole, when 400 ℃～450 ℃ garden steel by rolling the hole, can be rolled into the vertical bar Ribbed Bar, be changed roll, vertical bar Ribbed Bar that can rolling different size.
The utility model has the advantages that:
1, vertical bar Ribbed Bar that can rolling all size.
2, can combine with the hot rolling unit with the utility model, when the garden steel temperature that the hot rolling of hot rolling unit goes out is reduced to 400 ℃～450 ℃, but go out cold rolling vertical bar Ribbed Bar with the utility model tandem rolling, not only method is simple, cost is low, and mechanical performance of products is good.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is that the master of three milling trains of active three rollers looks schematic diagram.
Among Fig. 1, three garden sheet shape rolls 2 are arranged on the frame 5 of three milling trains of active three rollers, 3,4, there is concave arc ditch shape working face in the garden of roll on week, working face has falcate rib hole, three rolls 2,3,4 become three axles 1 at 60 ° of angles respectively mutually on frame 5,36, on 46, three rolls 2,3,4 become hexagonal angle mutually, three working faces surround garden shape and roll the hole, axle 1 two bearing blocks 21 that are installed on the frame 5, on 22, it is driving shaft, two axles 36 in addition, the 46th, countershaft is on driving shaft 1, the both sides of roll 2 have a bevel gear 23 respectively, 24, two countershafts 36 and 46 are installed in two pairs of bearing blocks 31 of a topping roll both sides respectively, 32 and 41, on 42, end in two countershafts 36 and 46, respectively have one respectively with driving shaft 1 on two bevel gears 23,24 bevel gears that are meshed 33,43, when rotating with Power Available Shaft 1, three rolls 2,3,4 can rotate synchronously, after three roll rotation, can roll into Ribbed Bar by rolling 400 ℃～450 ℃ garden steel in hole.For enough can the adjustment rolled hole shape, on the frame 5 at two pairs of bearing blocks 31,32 of two countershafts 36 and 46 and 41,42 other, there are two pairs to adjust bolt 34,35 and 44,45 respectively, an end of adjusting bolt 34,35 and 44,45 withstands on respectively on bearing block 31,32 and 41,42, rolls the shape in hole and makes bearing block 31,32 and 41,42 location in order to adjustment.Change the roll of different size, cooperate to adjust and roll hole shape, vertical bar Ribbed Bar that can rolling all size.
Claims (2)
1, three milling trains of a kind of active three rollers, comprise three garden sheet shape rolls that become hexagonal angle mutually, three rolls are becoming mutually on the frame on three axles at 60 ° of angles respectively, it is characterized in that: the both sides of an axle topping roll therein, a bevel gear is arranged respectively, an end of two axles in addition, respectively have one respectively with above-mentioned axle on two bevel gears that bevel gear is meshed.
2, by three milling trains of described active three rollers of claim 1, it is characterized in that: in the garden of described three garden sheet shape rolls concave arc ditch shape working face was arranged on week, falcate rib hole is arranged on the working face.
