钢筋调直机说明书

摘要

GT1.6/4型调直切断机主要由上料盘、调直装置、牵引装置、切断装置、下料架装置、机座等组成。主要用于直径为Φ1.6-Φ4mm低碳钢筋、冷轧钢丝、不锈钢丝的调制。

钢筋调直切断机在设计的时候需要考虑切断机构和调直机构的方案设计。根据任务书的要求，最终确定切断的方式为锤击切断方式：适用中、小直径钢筋，工作噪声连续、较大。易出现连切现象，定尺误差最小。调直的方式为模块调直：钢筋调直效果好，比较容易控制。但调直速度低，被加工钢筋表面有划伤，工作噪声较大；适合各种光圆钢筋。

该机器在运转时保证钢丝从左至右得方向进行送料；调直切断机在调试正常后，不允许有无效剪切现象；调直后的钢筋允许有轻微擦伤，但重量损耗不大于0.5％。

该调直切断机在设计完成后将满足的实际生产要求：（1）调直切断钢丝直径：Φ1.6-Φ4mm；（2）调直切断钢丝长度：100mm—1000mm；（3）切断长度误差：ΔL≤2mm；（4）钢丝调直切断后的直线度误差不大于2mm/m；（5）牵引钢丝速度：20-30m/min；（6）切断电机功率：2.2kw。

Abstract

GT1.6/4 type straightening cutting machine is mainly composed of loading plate, straightening device, traction device, cutting device, cutting device, frame, etc. Is mainly used for 1.6 Φ Φ diameter 4 mm mild steel, cold rolled steel wire, stainless steel wire of the modulation.

Steel bar straightening cutting machine at the time of design need to consider to cut off the institutions and straightening mechanism scheme design. According to the requirement of the specification, the final cut off the way for the hammer to cut off the way: for medium and small diameter steel bar, work continuously, large noise. Easy appear even cutting phenomenon, length minimum error. Module as a way of straightening straightening: reinforced straightening effect is good, easy to control. But straightening speed is low and processing steel surface is slashed and working noise; Suitable for

all kinds of round steel bar.

The machine in operation, ensure the wire feeding from left to right direction; Adjusting cutter after commissioning normal, there is no invalid shear phenomenon; After straightening steel to allow a slight abrade, but weight loss is not greater than 0.5%.

The straightening cutting machine in the actual production of the design is completed will meet requirements: (1) the straightening to cut off the wire diameter: 1.6 Φ Φ 4 mm; (2) the straightening cutting wire length: 100 mm - 1000 mm; (3) cutting length error: Δ L 2 mm or less; (4) steel wire straightening cutting off after the straightness error is not more than 2 mm/m. (5) the traction steel wire speed: 20-30 m/min. (6) to cut off the motor power: 2.2 kw. Key words:reinforced; Straightening cutting machine; Invalid shear
