Description

本考案は、建築鉄筋の直線矯正設備に係り、特に延伸機能を備える下部主動型混合圧力ロール式鉄筋直線矯正機に関する。 The present invention relates to a straightening facility for building rebar, and more particularly, to a lower main active mixed pressure roll type rebar straightening machine having a stretching function.

中国の最新修訂版の「コンクリート構造工事における工事品質検収基準」の５、３、２Ａ条の規定によると、コイル形式で供給する鉄筋につき、直線矯正後の許容単位長さ当たりの重量負偏差が≦８〜１０％である。すなわち、コイル形式で供給するＨＲＢ３００以下強度級の鉄筋につき、直線矯正後の許容単位長さ当たりの重量負偏差が≦１０％であり、コイル形式で供給するＨＲＢ３３５以上強度級の鉄筋につき、直線矯正後の許容単位長さ当たりの重量負偏差が≦８％である。該規定は、コイル鉄筋につき直線矯正加工時に一定量で延伸させた場合に鉄筋の強度が少し向上するが、その他の物理指標に大きな変化がなくしかも国家基準の範囲内に収まることに基づいて制定されたものである。したがって、コイル鉄筋につき直線矯正加工時に一定量で延伸させた場合、建築品質を向上させるだけではなく、建築用鋼材を大量に節約することもできる。 According to the provisions of Articles 5, 3, and 2A of the latest revised edition of "Construction Quality Inspection Standards for Concrete Structures", the negative weight deviation per unit length after straightening is corrected for reinforcing bars supplied in coil form. ≦ 8-10%. That is, for HRB300 or less strength class reinforcing bars supplied in coil form, the weight negative deviation per allowable unit length after straightening is ≦ 10%, and for HRB335 or more strength class reinforcing bars supplied in coil form, straightening The latter negative weight deviation per allowable unit length is ≦ 8%. This rule is established based on the fact that the strength of the reinforcing bar is slightly improved when the coil reinforcing bar is stretched by a certain amount during straight line straightening, but there is no significant change in other physical indicators and it is within the range of national standards. It has been done. Accordingly, when the coil reinforcing bar is stretched by a certain amount during straight line straightening, not only the building quality is improved, but also a large amount of building steel can be saved.

コイル鉄筋は、直線矯正機によって直線矯正加工を行われてから建築コンクリート内に使用されるようになる。一方、現在の鉄筋直線矯正機には、下記二種類の構造のものがある。 The coil rebar is used in building concrete after straightening processing is performed by a straightening machine. On the other hand, current rebar straightening machines have the following two types of structures.

１．回転フレーム式鉄筋直線矯正機
稼働時に、直線矯正ブロックまたは直線矯正ローラは、牽引されて通過する鉄筋周りにスパイラル動作をする。直線矯正ブロックまたは直線矯正ローラを鉄筋に過量に押圧すると、直線矯正後の鉄筋は、ツイストパンのようにねじるようになる。このような構造の鉄筋直線矯正機は、鉄筋を直線に矯正することができるが、鉄筋を延伸させることができない。 1. Rotating frame rebar straightening machine During operation, the straightening block or straightening roller spirals around the rebar that is pulled through. When the straightening block or the straightening roller is pressed excessively against the reinforcing bar, the reinforcing bar after straightening twists like a twist pan. The rebar straightening machine having such a structure can straighten the rebar, but cannot extend the rebar.

２．圧力ロール式鉄筋直線矯正機
該圧力ロール式鉄筋直線矯正機は、互いにずらした二列の直線矯正ロールと二列の直線矯正ロール軸と直線矯正ロールフレームからなる圧力ロール式直線矯正機構を含む。互いにずらした二列の直線矯正ロールは、直線矯正ロール軸を介して直線矯正ロールフレームに取り付けられ、下の列の直線矯正ロールは、直線矯正ロール軸を介して原動機の動力出力部材と接続する。すなわち、下の列の直線矯正ロールは、全て主動ロールであり、上の列の直線矯正ロールは、全て受動ロールである。被加工物である鉄筋は、主動ロールと受動ロールとの間にある。受動ロールは、調整機構を介して、主動ロールにおかれた鉄筋を湾曲させるように押圧する。主動ロールと受動ロールは、いずれも鉄筋の軸方向に沿って回転する。稼働時に、鉄筋は主動ロールに駆動されて止まることなく前進するが、多くの受動ロールは、前進し続ける鉄筋に押圧し、複数回にわたって湾曲させるように繰り返し、応力を除去し、直線矯正を実現する。鉄筋は、湾曲するたびに、本来わずかに伸長できるが、すなわち、湾曲回数と比例的に延伸することができる。しかし、下の列が全て受動ロールであり、また同一の速度で回転し、かつそれらの稼働径が同一であり、すなわち稼働面の線速度が一様であるため、鉄筋前進方向における前の主動ロールは、後ろから来る鉄筋の伸長を制限し、延伸させないようにする。 2. Pressure roll type rebar straightening machine The pressure roll type rebar straightening machine includes a pressure roll type straightening mechanism comprising two rows of straightening rolls, two rows of straightening roll axes and a straightening roll frame which are offset from each other. Two rows of straightening rolls shifted from each other are attached to the straightening roll frame via the straightening roll shaft, and the straightening rolls in the lower row are connected to the power output member of the prime mover via the straightening roll shaft. . That is, the straightening rolls in the lower row are all main driving rolls, and the straightening rolls in the upper row are all passive rolls. The rebar, which is the workpiece, is between the main roll and the passive roll. The passive roll presses the reinforcing bar placed on the main roll to bend through the adjusting mechanism. Both the main roll and the passive roll rotate along the axial direction of the reinforcing bar. During operation, the reinforcing bar is driven by the main roll and moves forward without stopping, but many passive rolls press against the rebar that continues to advance, repeatedly bending it multiple times, removing stress and realizing straightening To do. Each time a rebar is bent, it can naturally extend slightly, that is, it can be stretched in proportion to the number of bends. However, the lower rows are all passive rolls, rotate at the same speed, and their working diameters are the same, i.e., the linear velocity of the working surface is uniform, so that The roll limits the extension of the reinforcing bar coming from behind and prevents it from being stretched.

従来のコイル鉄筋に対して延伸、直線矯正加工を行うユニットは、後ろ側に独立した延伸機を設けるとともに、前側に独立した直線矯正機を設けて組み合わせたものである。延伸機は、鉄筋を一つの強力牽引機の牽引ロールと複数の受動延伸ロールに巻き付ける。牽引機を稼働させると、牽引ロールに巻き付けられた鉄筋は受動延伸ロールを通過するときに、湾曲を繰り返すことにより延伸を実現し、それから直線矯正機に入り直線矯正を実現する。該ユニットの不備として、（１）延伸、直線矯正を経た鉄筋、特にＨＲＢ３３５以上強度の異形鉄筋につき、リブ損傷が非常に大きいこと、（２）製造コストが高いこと、（３）稼働におけるエネルギー消費が大きいこと、（４）操作及びフィードがとても不便であることがある。 A conventional unit that performs stretching and straightening processing on coiled reinforcing bars is a combination of an independent stretching machine provided on the rear side and an independent straightening machine provided on the front side. The drawing machine winds a reinforcing bar around a pulling roll and a plurality of passive drawing rolls of one powerful traction machine. When the traction machine is operated, when the reinforcing bar wound around the traction roll passes through the passive stretching roll, the rebar is repeatedly bent to realize stretching, and then enters the straightening machine to achieve straightening. The deficiencies of the unit are: (1) Reinforced steel that has undergone stretching and straightening, especially deformed steel bars with strength of HRB335 or higher, that the rib damage is very large, (2) The manufacturing cost is high, (3) Energy consumption in operation (4) Operation and feed may be very inconvenient.

The upper traction roll is attached to the traction roll frame via a traction roll shaft and a bearing, the traction roll adjusting member is connected to the traction roll shaft, and the lower traction roll is connected to the power of the prime mover via the traction roll shaft.
