Description

Cold rolling reinforcing bar material loading mould alignment system

Technical Field

The utility model relates to a cold rolling reinforcing bar equipment, in particular to cold rolling reinforcing bar material loading part's mould alignment system belongs to cold rolling equipment technical field.

Background

In the production of cold rolled steel bars, a feeding machine mold plays a role in forcibly straightening the raw material steel bars, a production line runs at a high speed to change the coiled round raw material steel bars into straight strip-shaped key components, in the production, the steel bars are conveyed backwards under the driving of rear rolling mill power through the mold, the steel bars are straightened in the conveying process, the production line speed of the traditional cold rolled steel bars is low, the axial direction of a wire hole of a feeding mold in the production technology of the cold rolled steel bars is horizontal, the coiled round steel bars are fed in a flat mode, namely the axial direction of the coiled round is parallel to the axial direction of the wire hole of the mold, the mold is positioned behind the coiled round, in the process that the raw material steel bars enter the mold, the steel bars cannot be fully broken, even a plurality of circles can be simultaneously fed, and the accidents of steel twisting, steel piling and the like can occur at the mold when the production line speed reaches 300m/min, therefore, the method can be used under low-speed cold rolling, but cannot meet the requirement of high-speed cold rolling; secondly, vertical material loading, the axis of the wire rod is vertical to the ground in this state, a cross roller is arranged right above the wire rod, the die is arranged behind the cross roller and obliquely above the wire rod, and the reinforcing steel bar turns backwards through the cross roller and enters a wire hole of the die. The production speed of the existing cold rolling production line is developed to more than 1000m/min, so the current feeding die cannot meet the requirement of high-speed cold rolling in speed; the matching between the wire hole of the current die and the type and production speed of the wire rod is not good, the wire hole is small, the wire is well aligned but is easy to block, the wire hole is large, the wire hole is not easy to block but has short service life, the wire needs to be replaced when being worn to a certain degree, the traditional production line speed generally does not exceed 300m/min, the contradiction is not particularly obvious, the contradiction is obvious under the condition that the production line is greatly accelerated (such as 1000 m/min), the cold rolling speed at home and abroad does not have mature case which can reach 1000m/min, and the technology in the aspect is not provided for reference, so how to match the sizes of the wire hole and the section bar, the wire hole and the section bar can realize high speed and have longer service life, which is a problem to be solved in high-speed cold rolling, the current die adopts hard alloy steel for realizing wear resistance integrally, when the replacement is carried out, the whole body is required to be replaced, so that the consumable cost is high.

Disclosure of Invention

An object of the utility model is to overcome the above-mentioned problem that exists in the production of present high-speed cold rolled steel bar, provide a cold rolled steel bar material loading mould alignment system.

In order to realize the purpose of the utility model, the following technical proposal is adopted: the straightening system of the cold-rolled steel bar feeding die is characterized in that the cold-rolled steel bar feeding die adopts vertical feeding, the axis of a coil is in the vertical direction, a die is fixedly arranged right above the coil, a wire hole of the die is in the vertical direction, the central line of the wire hole of the die and the axis of the coil are on the same straight line, the distance between the wire hole of the die and the uppermost end of the coil is more than or equal to 5.5 meters, and the diameter difference between the wire hole of the die and a steel bar is 3-6 mm.

Further, the method comprises the following steps of; the diameter difference between the wire hole of the die and the reinforcing steel bar is 4 mm.

Further, the method comprises the following steps of; the upper part of the mould is provided with a steering wheel, the axis of the steering wheel is in the horizontal left-right direction, and the distance between the tangent line of the vertical direction of the steering wheel close to the axis side of the mould line hole and the mould hole is 4-7 mm.

Further, the method comprises the following steps of; the die is a combined die, the combined die comprises a carbon steel shell, a hole is formed in the carbon steel shell, and an inner sleeve which is made of hard alloy and provided with a die line hole is embedded in the hole of the carbon steel shell.

The utility model discloses an actively beneficial technological effect lies in: the axis of this system mould adopts upper and lower direction, and be greater than 5.5 meters below the mould apart from above the raw materials, the distance has certain high back, can make the raw materials reinforcing bar fully fall open at the in-process that rises, the reinforcing bar is the heliciform and rises, in addition, the action of gravity of material loading in-process, even the production line speed reaches 1000m/min, also can avoid the hank steel, pile the steel, the mould is located directly over the raw materials, and the reinforcing bar is the heliciform and rises and has avoided the single department friction of reinforcing bar mould particular position, cause the mould loss too fast, the alignment effect to the reinforcing bar can enough be realized to the suitable diameter size in mould line hole, the long-life of mould can also be realized, the combined die structure has reduced carbide's use amount. The die system can solve the problem of high cost of steel stacking, steel twisting and die consumable materials at the die under the condition of high-speed cold rolling.
