There is following defective in the descaling device of above-mentioned prior art:
1. the position between the de-scaling running roller of prior art needs to regulate leading screw or electronic mode such as depress is adjusted with manual adjustment, has complex structure, the higher defective of cost.
2. because reinforcing bar moves on a plurality of de-scaling running rollers of intervening portion up and down in same vertical plane, and reinforcing bar only is subjected to the frictional force of upper and lower surface, scale removal effect is not good.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, a kind of simple in structure, easy to operate, descaling device of a plurality of faces of reinforcing bar being carried out a kind of cold rolled reinforcing bar milling train of effective de-scaling is provided
The technical scheme that solves the problems of the technologies described above is: a kind of descaling device of cold rolled reinforcing bar milling train, described descaling device comprises: frame, frame are provided with that reinforcing bar enters and pass advances silk mouthful and filament mouth, de-scaling running roller, described de-scaling running roller comprises the first de-scaling running roller and the second de-scaling running roller, the vertical mutually and setting at interval of the axial line of the described first de-scaling running roller and the second de-scaling running roller; The roller groove center of the roller groove center of the first de-scaling running roller and the second de-scaling running roller is positioned on the same horizontal line.
The invention has the beneficial effects as follows: the present invention overcomes the defective of prior art, can realize the dephosphorization of better quality, greater efficiency, and it is easier to operate, and ensures operator's safety to greatest extent, realizes the hommization mode of operation.The present invention has simple in structure, and is easy to operation, by rebar surface is subjected to uniformly and running roller between frictional force, to a plurality of de-scalings of reinforcing bar, remove rebar surface oxide skin; Also have the production efficiency height simultaneously, easy to maintenance, stable working is saved energy consumption, the advantage that processing cost is low.

The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.
Fig. 1 is a front view of the present invention; Fig. 2 is the vertical view of Fig. 1; Fig. 3 is a pilot bushing cutaway view among Fig. 1; Fig. 4 is the first de-scaling running roller and the second de-scaling running roller cutaway view among Fig. 1.
The invention provides a kind of descaling device of cold rolled reinforcing bar milling train, described descaling device comprises: frame 5, frame 5 are provided with that reinforcing bar 8 enters and pass advances silk mouthful 1 and filament mouth 6, de-scaling running roller.
Described de-scaling running roller comprises the first de-scaling running roller 4 and the second de-scaling running roller 2, the vertical mutually and setting at interval of the axial line of the described first de-scaling running roller 4 and the second de-scaling running roller 2; The roller groove center P2 of the roller groove center P1 of the first de-scaling running roller and the second de-scaling running roller is positioned on the same horizontal line.
Described first de-scaling running roller 4 and identical the including of the second de-scaling running roller, 2 structures: running roller 2c, central shaft 2b; The bolt of described central shaft 2b one end is fixed on the frame 5 with locknut 2a, and the central shaft 2b other end is by the hinged running roller 2c of bearing 2d; Running roller 2c outer rim is provided with the semicircle roller groove 7a that caves inward; Running roller 2c end face is equipped with running roller gland 2e
At the first de-scaling running roller 4 with advance between the silk mouthful 1 to be provided with pilot bushing 3, described pilot bushing 3 comprises: back-up block 3a, hole are with back-up ring 3b, wear-resistant block 3c; Described back-up block 3a is the shoulder hole that there is perforation at the center; The hole is stuck in the interior hole slot of back-up block 3a with back-up ring 3b; Wear-resistant block 3c is clamped on the side of shoulder hole in the back-up block 3a with back-up ring 3b by the hole.
