Said roller scoring machine is composed of base, frame, ratary supporter, rotary sleeve tube of roller supporter, regulation screw arbor, press-down mechanism of roller and two sets of combined rollers (2 or 3 ragging rollers for each). Its roller ring has long service life.
Description
The invention belongs to the apparatus for cold rolling of metal processing, particularly a kind of continuous process units of prestressed concrete reinforcing steel.
Prestressed concrete reinforcing steel is the high strength cast iron of a kind of mild steel heat treatment reinforcement or high-carbon steel cold-work strengthening, because it has intensity height (yield strength 1275MPa, more than the tensile strength 1422MPa), good percentage elongation and low loose rate (1000h is less than 2.5%), good bond stress (rebar surface has 3～6 helical groove lines) is widely used in skyscraper, harbour, bridge pier with in concrete tubular pile, Longspan Bridge and the railroad sleeper.It is compared with the hot-rolled reinforced bar with steel grade, can replace the hot-rolled reinforced bar of ∮ 20mm with the prestressed concrete reinforcing steel of ∮ 11mm.Be used for the skyscraper ground and compare, save steel 60%, improved construction quality, improved building speed with existing method.
In the prior art, what prestressed concrete reinforcing steel adopted is wire drawing die drawing moulding, and the wire drawing die endoporus is made up of the multi-head spiral line.Under the effect of pulling capacity, wire drawing die forms helix around the rotation of drawing center line at rebar surface.Because the wearing and tearing of the effect wire drawing die of frictional force are big, the wire drawing die life-span is short, generally has only 5～10 tons, and can not rebuild use; Because in the wire drawing die is the multi-head spiral line, wire drawing die is made difficult cost height; Wire drawing die is to the lubricating requirement height; Want earlier that reinforcing bar is pinching during die change.Owing to above reason, domestic existing production is all adopted and is shaped to a line, heat treatment is another line, can't form a moulding and the incorporate tinuous production of heat treatment (1.Heat treatments of steel Bar for prestessed concrete TakaoYAMAZAKI and Eiji YAMASMTA, " HEAT TREATMENTS ", 20 (1980), 4, Japan; 2.Hi-Bondwire for producing PHC pipe Song pile " metallic article ", P14-16, Vol.21,5 (1985) of waiting for army building).
The object of the present invention is to provide a kind of device for producing prestressed concrete reinforcing steel that can realize the moulding of continuous rolling indentation and can form integrated production line with heat treatment.
At above-mentioned purpose, the present invention has adopted following technical scheme:
Reinforcing bar producing device comprises actinobacillus device, descaling device, tube reducing device, drawbench, straightener, pressure roller feeder, annealing device, cutter and winder on the existing conventional prestressed concrete.Major technique feature of the present invention is exactly to have assembled a bench roller to roll scratching device between the tube reducing device of above-mentioned process units and drawbench, finishes the indentation of steel disk with this.The indentation of this device is a passive type, and it is driven by the drawbench of front.And the rolling scratching device mainly is made up of two groups of combination rollers and roll screw-down, and each group combination roller is made up of three indentation rollers (corresponding to 3 and 6 helical grooves), also can be made up of two indentation rollers (corresponding to 4 helical grooves); It is on the rotating basis that the helical disk of two groups of combination rollers by the roll screw-down is installed in two relative rollers with axle, can rotate with pedestal.The rolling surface of indentation roller becomes the α angle with the central horizontal line of whole production device, and the pitch angle alpha will of the prestressed concrete reinforcing steel that this α angle is just made can be adjusted the α angle by helical disk 16.When α=0, change the collars of difformity decorative pattern, can roll out the reinforcing bar of corresponding decorative pattern.
Compared with prior art, the present invention has following advantage:
1, the rolling indentation organically combines rolling advantage with drawing, because collars is passive rotation, it has changed the wire drawing die Frotteurism.The general wire drawing die life-span is 5～10 tons just scraps, and collars adopts the carbide alloy material, and its life-span, wearing and tearing back collars can be rebuild use more than 500 tons.Wire drawing die is to the lubricating requirement strictness, and the rolling indentation is low to lubricating requirement.
2, the helix of wire drawing die is made complexity, and the collars making is simpler.The roll process indentation is as long as change the angle [alpha] of helical disk.Just can change the pitch angle alpha will of prestressed concrete reinforcing steel, and roll change ring in addition.According to roll quantity is installed, helix can be 3,4,6, can be left-handed also can be dextrorotation.Product specification is ∮ 3～∮ 13mm.
3, wire drawing die wear mould must steel disk is earlier pinching, and the moulding of roll process indentation can onlinely be depressed, depth of cup can be regulated, also need not be pinching, therefore operation is easier.
4, wire drawing die is because the life-span is short, and die change is frequent, so each die change production line will be shut down, and heat treatment is in case shutdown, and the reinforcing bar in stove then is a waste product.Therefore, a production line is generally all formed in wire drawing die drawing moulding separately, adopts the moulding of rolling indentation then can be unified into a line with heat treatment.
5, roll process indentation, when α=0, fixing rotating basis (13), the shape that changes collars and decorative pattern just can be produced the reinforcing bar of different decorative patterns.
Below in conjunction with accompanying drawing the present invention is further described.
Accompanying drawing 1 is a technological process layout drawing of the present invention.
Accompanying drawing 2 is the structural representation of rolling scratching device of the present invention.
Accompanying drawing 5 is the structural representation of indentation roller.
By accompanying drawing 1 as can be known, device for producing prestressed concrete reinforcing steel of the present invention is made up of actinobacillus device 1, descaling device 2, tube reducing device 3, rolling scratching device 4, drawbench 5, straightener 6, pressure roller feeder 7, annealing device 8, cutter 9 and winder 10.
Find out that by accompanying drawing 2 rolling scratching device 4 is that rotating basis 13, roller support turnbarrel 20, adjusting screw(rod) 21, roll screw-down and two groups of combination rollers are formed by base 11, support 12, roller.Wherein the roll screw-down is formed by depressing adjusting nut 14, axle 15, helical disk 16.And as shown in Figure 3, each group combination roller also can be made up of two indentation rollers (corresponding to 4 helical grooves) three indentation rollers 17 (corresponding to 3 and 6 helical grooves).Fig. 5 illustrates each indentation roller 17 and is made up of collars 25, collars seat 23, bearing 27, bearing sleeve 28 and pad 24.
In rolling scratching device 4, support 12 is configured on the slideway of base 11, and promptly support 12 is movably; The adjusting nut 14 of roll screw-down links to each other with support 12 by bearing 29; Helical disk 16 and the axle 15 of two groups of combination rollers by the roll screw-down is installed on two rotating basis 13; Rotating basis 13 links to each other with support 12 by bearing 30; Adjusting screw(rod) 21 and support 12 link to each other with screw form; Two turnbarrels 20 are connected as a single entity two rotating basis 13 by screw 31.Two groups of combination rollers are arranged on the same horizontal axis, and every group of combination roller is assemblied on two supports 12 by the roll screw-down.In addition, the spacing between the rotating basis 13 of two groups of combination rollers is regulated by screw rod 21.Found out that by Fig. 4 the rolling surface of indentation roller 17 becomes the α angle with the horizontal axis of whole production device, the α angle is controlled at: 0＜α＜90 °.The α angle just the helical angle of rolling prestressed concrete reinforcing steel, can control the α angle by adjusting helical disk 16; When α=0, change the collars 25 of difformity decorative pattern, can roll out the reinforcing bar of corresponding decorative pattern.32 is the reinforcing bar that is rolled among Fig. 4.
