How To Improve the Efficiency of the Bar Straightening Machine?
What’s the steel bar straightening machine?
The steel bar straightening machine is a commonly used equipment on the construction site. The device is firstly driven by a motor to increase the speed through a belt-drive so that the straightening cylinder rotates at a high speed, the steel bars passing through the straightening cylinder are straightened, and the rust on the surface of the steel bar is removed by the straightening die; Driven by the electric motor through another pair of reduction belts and gear reduction box, on the one hand, it drives the two conveying rollers to pull the steel bars forward, and on the other hand, drives the crank wheel to move the hammerhead up and down. When the steel bar is adjusted to the predetermined length, the hammerhead strikes the upper tool post to cut the steel bar. When the cut steel bar falls into the receiving rack, the tool post returns to its original position due to the action of the spring, completing a cycle.
When using the steel bar straightening machine, pay attention to the following 6 points, which will greatly improve the production efficiency.
- Choose the right carbide straightening dies.
According to the diameter of the steel bar to be straightened, select a suitable carbide straightening die. The bore size of the straightening block should be 2～3mm larger than the diameter of the steel bar to be straightened. The first and last two wire guide dies must be placed on the center line of the straightening cylinder, and the middle three can be offset from the center line. Generally, firstly, make the steel bar have an offset of 3 ram. After trial straightening, if it is found that the steel bar still has a slow bending phenomenon, correct it by gradually adjusting the offset until the steel bar can be straightened.
- Enough space
In order to ensure the safety and quality of the steel bar straightening operation, the straightening and cutting machine should be installed on a solid concrete foundation, and a hangar should be set up for outdoor operations, and there should be enough space for stacking raw materials and semi-finished products next to the hangar.
- The support frame installation
The support frame should be installed straight and its center should be aligned with the center line of the guide tube, the straightening tube and the lower cutter hole. The steel bar turntable should be installed at a distance of 5-8m from the straightening machine.
- Machine unloaded
Before starting work formally, run the steel bar straightening machine without load for 2 hours, and then check the temperature of the bearing, check whether the hammer head, cutter or cutting gear is working properly, and after confirming that there is no abnormal condition, the material can be fed and tested for adjustment. Straight and cut off ability.
- Check firstly
The newly installed steel bar straightening machine must first check whether the electrical system and parts are damaged, whether the connections and connectors of each part are firm and reliable, whether each rotating part is flexible, whether the performance of the transmission and control system meets the requirements, and all the above aspects are in compliance. After request, the trial operation can be carried out.
- Adjust the cutter
Adjust the fixed cutter appropriately according to the position of the movable cutter. The blade gap of the upper and lower cutters should be no more than 1mm, and the lateral gap should be no more than 0.10～0.15mm.
