Abstract
The utility model relates to a mechanical steel bar hardening eliminator which is a device used for eliminating work hardening of cold-rolled ribbed steel bars under the prerequisite of steel bar intensity assurance. The utility model is composed of a transmission mechanism, a horizontal bending roller set, a vertical straightening roller set, and a roller shaft radial adjustment mechanism. The utility model is characterized in that horizontal bending rollers 4 to 12 are driven to rotate by a gear transmission 19, a ribbed bar 16 is repeatedly bent and deformed among the horizontal bending rollers 4 to 12, and side straightening of the ribbed bar is carried out by the vertical straightening roller set 15. The utility model has the advantages that the internal structure of the steel bar can be improved, the work hardening can be eliminated, and the mechanical property of the steel bar can be improved. Compared with an existing heat treatment technology, the investment can be greatly decreased, the energy consumption can be saved, and the environmental pollution can be avoided.
Description
The utility model belongs to the reinforcing bar processing technique field, is specifically related to a kind of device of eliminating cold rolled reinforcing steel bar with ribs work hardening.
Cold rolled reinforcing steel bar with ribs is a raw material with the gren rod, after cold rolling, has not only improved the mechanical property of reinforcing bar, and makes its surface with ribbing, thus improved reinforcing bar intensity and with concrete bond stress.Yet because the influence of work hardening reduces the plasticity index of reinforcing bar, thereby quality product is descended.
In order to eliminate the defective that cold rolled reinforcing steel bar with ribs brings owing to work hardening, improve its mechanical property, at present, extensively adopt heat treatment technics, the Ribbed Bar that is about to web-like places bell furnace, or in the process furnace of other type, heat and insulation annealing, improve the reinforcing bar internal crystal structure, reduce internal stress, reduce the influence of work hardening, thereby improve its plasticity index.
Adopt the weak point of aforesaid method to be that facility investment is big, complex process, the energy consumption height also can produce environmental pollution.Simultaneously, the reinforcing bar coil annealing owing to the difference of temperature causes with shortcomings such as coil biceps performance difference are bigger, has influenced the quality of reinforcing bar.
The objective of the invention is in order to overcome the shortcoming that prior art exists, a kind of mechanical type reinforcing bar sclerosis cancellation element is provided, allow the Ribbed Bar after cold rolling produce the alternating bending distortion, thereby improve its mechanical property.
The present invention seeks to realize like this: as Fig. 1, shown in Figure 2, this device is by transmission rig, horizontal curvature roller group, vertical straightening roll group and roll shaft radially adjustment mechanism are formed, it is characterized in that described transmission rig is joining with the output shaft of the wheel casing of cold rolled reinforcing steel bar with ribs milling train, and the gear mechanism 19 of drive horizontal curvature roller rotation, horizontal curvature roller component two rows are arranged, foremost (left end) pair of rolls 4 and 5 and backmost (right-hand member) pair of rolls 12 and 11 axis are to be positioned at same vertical plane, all the other rollers 6,7,8,9, the 10th, staggered arrangement, the lower roll axis is fixedly mounted on the same horizontal plane, last row's roller then is installed in the bearing support that can transpose, according to processing requirement, by adjusting the requirement that pressure screw 2 is realized the bar bending degree.All the working diameter of bending roll all increases progressively by 2-3%, to realize that rolled piece is parted a little power to pinch, prevents the rolled piece accumulation.Driven pinch roll 25 is installed in the roller 8 following same vertical planes, realizes pinching the smooth progressive purpose of reinforcing bar.Described vertical straightening roll group as shown in Figure 4, staggered about on the horizontal plane being, each straightening roll all is installed in the bearing support that can transpose, in order to guarantee normally to nip, in vertical straightening roll group front (left side) pressure roller 14 is installed, pressure roller shaft can be transposed up and down by adjusting screw 13.The roll shape curve of last horizontal curvature roller is " V " type, and the roll shape curve of following horizontal curvature roller is " V " type or garden cylindricality.The roll shape curve of vertical straightening roll is the garden arc.Described roll shaft adjustment mechanism is to adopt nut screw adjustment mechanism as shown in Figure 3, Figure 4.For reinforcing bar is nipped easily, (left end) is equipped with inlet guide and guards 1 before horizontal curvature roller group.
Advantage of the present utility model and positively effect:
1, technical solutions of the utility model produce the alternating bending distortion by making the reinforcing bar after cold rolling, change the weave construction of its metal inside, have eliminated the work hardening influence, have improved mechanical property.As to Q235 Φ 6-Φ 12 cold rolled reinforcing steel bar with ribs, guaranteeing its intensity σ
bUnder the preceding topic of 〉=550Mpa, its unit elongation δ
108-10% can be reached, and the planeness of reinforcing bar scale material can be improved.
2, the utility model is simple in structure, and is easy to operate, can replace Equipment for Heating Processing within the specific limits, can reduce investment outlay, and saves the energy, avoids environmental pollution, has tangible economic benefit and social benefit.

Embodiment:
As shown in Figure 1 and Figure 2, the utility model device has been installed in back at Y220 type cold rolled reinforcing steel bar with ribs milling train, Ribbed Bar 16 enters between the horizontal curvature roller 4-12 through inlet guide and guard 1, carry out the alternating bending distortion, make the reinforcing bar crystal inside under the repeated stress effect, produce dislocation and slippage, and rearrange, the metal inside weave construction is improved, plasticity index is improved.Horizontal curvature roller 4-12 is by gear drive 19 driven rotary, driven pinch roll 25 is installed in the bending roll 8 following vertical planes, and 19 of gear drives are joining with the output shaft of the wheel casing of tandem mill for cold-rolled ribbed reinforcing bar by shaft coupling 17.The size of bar bending degree is according to processing requirement, by roll shaft radially adjustment mechanism (being pressure screw 2) realize that reinforcing bar enters vertical straightening roll group 15 through pressure roller 14 again and carries out the edge bending aligning through after the alternating bending distortion, improve its planeness, carry out cutting to length at last.Reinforcing bar after this device is handled is as to Q235, Φ 6-Φ 12, its intensity σ
b〉=550MPa, unit elongation δ
10〉=8-10%, other index all satisfies the GB13788-92 standard.
