Description
Technical field
The present invention relates to a kind of processing and processing technology field of wire rod, particularly relate to a kind of hub concrete-bar straightening-cutting machine that changes more.
Background technology
Along with the fast development of wire rod processing industry, the specification requirement of concrete-bar straightening-cutting machine also being improved constantly. existing concrete-bar straightening-cutting machine technology and product can not satisfy the requirement of wire rod processing industry fast development far away.There is following problem in existing concrete-bar straightening-cutting machine: one, in prior art and product; The straightening of concrete-bar straightening-cutting machine is changeed hub (or claiming straightening drum) and is gone up hyperboloid straightener roll (abbreviation straightener roll) or the straightening module (being called for short the straightening piece) that is provided with, and the distance of changeing the hub axis direction in straightening all is by corresponding type: like LGT6/12, and GT6/12; GT3/8 etc. design by maximum bar diameter; And be changeless, no matter the size of bar diameter, the height of reinforced steel bar strength has only the constant deformed area of a kind of size; Adaptive capacity to reinforcing bar is very poor, and the straightening quality is not high yet.Two, the hyperboloid of straightener roll is by the maximum bar diameter design of corresponding type such as LGT6/12; And the angle of the axis of straightener roll and reinforcing bar axis is fixing nonadjustable; If its contact-making surface of the reinforcing bar of straightening minor diameter has just diminished; Will extrude the little curved of even branch at rebar surface, the straightening quality is descended.Three, the big straightening piece of bar diameter with macropore; The little straightening piece of bar diameter with aperture, the pore size of straightening piece will be changed along with the size of bar diameter at any time, once all wastes time and energy very much like GT3/8, the every replacing of GT6/12; Increased when attaching the assistant engineer, production efficiency is reduced.Four, have only straightening to change hub at the reinforcing bar axis direction, make the reinforcing bar axis direction after the straightening be prone to distortion.Five, the scale of LGT spiral aligning cutting-off device yarn row product is inaccurate, and it is bigger to cut off error.Six, GT concrete-bar straightening-cutting machine series of products, the blow tank on the scale bin, the reinforcing bar of a kind of diameter of every replacing must be adjusted the width of a blow tank; The scale plate moves on blow tank or obstacle is arranged during definite scale position; Must pull down barriers during scale, both bother, waste man-hour again.Seven, to attack rate big, not laborsaving for shut-off mechanism, wastes energy.
