目前细钢筋弯曲加工机械一般都只能在一机上弯曲单一的角度,有的机械虽能一机弯曲二、三种角度,但必须同时用2～3人采用推磨式的流水方式操作;或虽一机同时弯曲多种角度,但只能用于定型产品,专机专用,不易变换尺寸和弯曲形状。对于有多种弯曲角度的钢筋(图1)基本上还采用原始的手工操作方法,劳动强度大,工效低,质量也无法保证。为改革这一工艺,适应产品不定型的生产要求,我厂制成了12—4型可调程序钢筋弯曲机,用于加工不定型的细钢
At present, the fine steel bar bending and processing machines are generally only able to bend a single angle on one machine. Some machines can bend two or three angles in one machine, but they must use 2 to 3 people at the same time to use a push-type water flow mode; or Although a machine bends a variety of angles at the same time, it can only be used for shaping products, special planes, not easy to change the size and bending shape. For the steel bars with various bending angles (Fig. 1), the original manual operation method is basically adopted, and the labor intensity is large, the work efficiency is low, and the quality cannot be guaranteed. In order to reform this process and adapt to the production requirements of indeterminate products, our factory has made a 12-4 type of adjustable program steel bending machine for processing amorphous steel.
