The working principle of the straightening machine:
In order to straighten the cylinder, the steel bar comes out of the disc rack and enters the cylinder. The adjusting screw of the straightening block is appropriately adjusted, and the straightening block is fastened at different eccentric positions to straighten the steel bars of different specifications or different properties. .
The straightening schemes are Gaussian, sinusoidal and cosine, which are suitable for steel bars of different diameters and different yield strengths.
After straightening multiple rebars, the straightening block will wear out. At this time, the eccentricity should be compensated to ensure the straightening effect. In order to straighten the main transmission box and the traction pressure roller, the mechanical speed reduction mechanism reduces the motor rotation speed in the transmission box, and drives the active pressure roller (upper pressure roller) to rotate. When feeding, rotate an eccentric handle to raise the upper pressure roller, pass the steel bar through the V-shaped groove between the upper pressing roller and the lower pressing roller (passive pressing roller), and then rotate the eccentric handle in the opposite direction to make the upper pressing roller Put down, the upper and lower pressure rollers are in the state of clamping reinforcement. The material pressure is between the two pressure rollers, and the strength of the adjusted steel bar depends on the clamping force between the pressure rollers. The connecting rod mechanically connected with the upper pressing roller is connected with a spring, and the spring applies pressure to the upper pressing roller. The traction force of the pressing roller is proportional to the pressure, so different spring pressures should be selected for the steel bars of different diameters and materials. Thereby the steel bar is better gripped and pulled. At the same time, in order to prevent the continuous cutting phenomenon during shearing, when the steel bar is stopped at the top, the steel bar and the pressure roller should have obvious slippage. Therefore, the adjustment of the spring pressure is the key to whether the straightening machine can work normally.
The straightening machine is sometimes called a straight wire machine because most of the time it is straightening the wire, so it is named after this. The main structural components of the straightening machine are a straightening cylinder, a pulling mechanism, a cutting mechanism, a steel fixed length frame, a frame and a driving device.
The working principle of the straightening machine: the motor drives the belt drive, and can make the straightening cylinder rotate at a high speed, so that the steel bar passing through the straightening cylinder is straightened and the scale of the steel surface is removed; and then the motor passes through another pair of speed reducing belt transmission and gear The reduction box can drive two conveying rollers, so that the steel rod can be pulled forward and the crank wheel can be driven to move the hammer head up and down. When the reinforcing bar is adjusted to the predetermined length, the hammer will hammer the upper tool holder to cut the steel bar. When the cut steel bar falls into the receiving frame, it will be subjected to the elastic force of the spring, and the knife table will return to the original position. A work cycle has been completed. The characteristics of the work of the straightening machine are mainly that the incisions are very neat and the error is small, and the straightening effect is good.
Steel bar straightening machine operating procedures
1. According to the diameter of the straightened steel bar, select the appropriate straightening block, the boring wheel groove and the transmission speed. The diameter of the straightening block should be 2 to 5 mm larger than the diameter of the reinforcing bar, and the groove width of the traction sheave is the same as the diameter of the straightened bar.
Second, the adjustment of the straightening block. There are five straightening blocks in the general straightening cylinder. The first and fifth straightening blocks must be placed on the middle line, and the middle three can be off center line. First shift the steel bar by about 3mm, and after trial adjustment, if the steel bar still has a slow bend, gradually increase the offset until it is straightened.
3. After cutting off the three or four steel bars, it is necessary to stop the inspection to check whether the length is appropriate. If there is any deviation, adjust the limit switch or the fixed length plate until it is suitable.
5. Before the straightening block is not fixed, the protective bar is not covered, and the steel bar should not be put in to prevent the straightening block from flying out and hurting people.
6. It is not allowed to stack objects on the machine to prevent mechanical vibrating objects from falling into the body. The steel bar is loaded into the pressure roller, and the hand and the roller should be kept at a certain distance. The roller must not be adjusted during the operation of the machine, and it is strictly forbidden to wear gloves.
Seven, the steel bar is adjusted until the end, the personnel must avoid, in order to prevent inciting people. Steel bars shorter than 2 m or larger than 9 mm in diameter should be straightened and processed at low speed.
