★弯曲钢筋时,严禁加工超过机械规定的钢筋直径、根数及机械转速。
★弯曲高硬度或低合金钢筋时,应按机械铭牌规定换标A大限制直径,并调换相应的芯轴。
★严禁在弯曲钢筋的作业半径内和机身不设固定的一侧站人。弯曲好的半成品应堆放整齐,弯钩不得朝上。
★换向时,必须在停稳后进行。
★作业完毕、清理现场、保养机械、断电锁箱
Fourth, the method of use:
★ Check that the mechanical properties are good, the workbench and the bending machine table are kept level; and various mandrel tool stops are prepared.
★ Install the mandrel, the forming shaft, the iron retaining shaft or the variable retaining frame according to the diameter of the processed steel bar and the bending machine. The diameter of the mandrel should be 2.5 times the diameter of the reinforcing bar.
★ Check the mandrel, the block, no damage and cracks, the shield is fast and reliable, and it can be operated normally after the operation of the empty machine.
★When working, insert one end of the steel bar into the fixed gap, and the other end is fixed close to the fuselage and pressed by hand. Check the fuselage and fix it. It is safe to block the side of the steel bar.
★ It is strictly forbidden to replace the mandrel, change the angle and speed control during the operation, and do not add or remove oil.
★ When bending steel bars, it is strictly forbidden to process the diameter, number of roots and mechanical speed of the steel bars exceeding the mechanical specifications.
★ When bending high hardness or low alloy steel bar, the maximum limit diameter should be changed according to the mechanical nameplate and the corresponding mandrel should be exchanged.
★ It is strictly forbidden to stand in the working radius of the bending bar and the side where the body is not fixed. The bent semi-finished products should be stacked neatly and the hooks must not face upwards.

五,操作规程
1、在被检验的金属线材上截取长200mm-500mm的一段,进行矫直,矫直时不得损伤线材表面。
2、按照参数表中线材直径大小选择夹片圆弧半径r,夹片圆弧顶部至拨杆底面的距离b,以及拨杆孔φ。
3、主杆上有相互垂直的四个孔,调正拔杆的方向可得到你所需要的孔位。
4、将摇臂处于垂直的位置,并以此作试验的起始状态,将试样先穿入两面三刀夹片中底板的孔内,然后垂直向上从拨杆的下部穿过拨杆孔再穿入上夹至顶部,转动上夹头手柄把线材上端的夹紧。
5、用手把上夹头往下按15-25mm后稳住,转动主夹片手柄将下端夹紧进行弯曲。
6、弯曲试样时,应使用较均匀的速度(约1次/秒)。
7、弯曲记数是从起始位置向右弯曲90度,试样返回至起始位置为A次,再向左弯曲90度,试样再返回起始位置为第二次以此类推至试样折断为止,试样折断的A后一次弯曲次数不计。
8、长期使用后夹片的园弧表面若出现压伤的痕迹应更换夹片
9、油杯及有相对滑动处应经常加油,保持润滑。
10、使用后应擦拭干净并涂上防锈油以防锈蚀。
Five, operating procedures
1. Cut a length of 200mm-500mm on the metal wire to be inspected, straighten it, and do not damage the surface of the wire when straightening.
2. According to the diameter of the wire in the parameter table, select the radius r of the clip, the distance b from the top of the clip arc to the bottom of the lever, and the hole φ of the lever.
3. There are four holes perpendicular to each other on the main rod. Adjust the direction of the rod to get the hole position you need.
4. Place the rocker arm in a vertical position and use this as the initial state of the test. Insert the sample into the hole in the bottom plate of the two-sided three-knife clip, and then vertically upward from the lower part of the lever through the hole of the lever. Insert the upper clamp to the top and turn the upper grip handle to clamp the upper end of the wire.
5. Press the upper clamp down 15-25mm by hand and stabilize it. Turn the main clamp handle to clamp the lower end to bend.
6. When bending the specimen, use a more uniform speed (about 1 time / sec).
7. The bending count is bent 90 degrees from the starting position to the right. The sample is returned to the starting position for the first time, then bent 90 degrees to the left, and the sample is returned to the starting position for the second time and so on. The number of times the last bending of the sample is broken is not counted until the sample is broken.
8. If the surface of the circular arc of the clip is used after long-term use, the clip should be replaced.
9. Oil cups and relative sliding parts should be refueled frequently to maintain lubrication.
10. Wipe clean and apply anti-rust oil after use to prevent corrosion.
