Description

Technical Field

It also refers to the construction of various houses and buildings, also known as construction workload. This part of the investment must be started and materials can be realized through construction activities. Among them, one of the indispensable materials for bridges and road construction in construction projects is steel bars, but during the production and transportation of steel bars, it is easy to cause the steel bars to bend, and then fail to meet the construction needs, so the cooperation of straightening machines is required.

[0003] At present, when a straightening machine is used to straighten steel bars, it is often necessary to use the pressure wheels relatively arranged up and down and the pressure wheels relatively arranged left and right inside the straightening machine to perform rolling and adjusting work on the steel bars. However, since the steel bars have different thicknesses, when the straightening machine is used to straighten steel bars of different thicknesses, it is necessary to adjust the spacing between the pressure wheels in different directions. However, although most of the existing straightening machines have the function of adjusting the pressure wheels in different rolling directions, most of them are separate adjustments in the same relative direction, so that the pressure wheels in different relative directions need to be adjusted multiple times, which not only increases the adjustment time of the pressure wheel spacing and reduces the straightening efficiency of the steel bars, but also adjusts the spacing in batches, which is also easy to make the distances between the pressure wheels in different relative directions different, thereby reducing the subsequent straightening quality of the steel bars.

[0004] Therefore, it is necessary to provide a kind of municipal construction construction steel bar straightening machine to solve the above-mentioned technical problems. Utility Model Content

The spacing between the several pressing wheels 5 on the two mounting frames 2 is adjusted, and the downward movement of the rack 10 drives the gear 9 meshing therewith to rotate, and the gear 9 drives the bidirectional threaded rod 8 to rotate. Under the limiting cooperation of the slide groove 11 and the slider 12, the two adjustment plates 6 drive the corresponding pressing wheels 2 7 to move relatively along the axial direction of the bidirectional threaded rod 8, so that the spacing between the pressing wheels 2 7 on the two adjustment plates 6 can be adjusted synchronously, and after the adjustment is completed, the bidirectional threaded rod 8 is further fixed and limited by inserting the pin 20 into the slot 18 and the two fixing plates 19;

[0034] After adjusting the spacing between the pressure wheels 1 5 on the two mounting frames 2 and the spacing between the pressure wheels 2 7 on the two adjustment plates 6 at the same time, the two motors 14 are started through the control box 17, so that the output ends of the two motors 14 rotate relatively, and under the transmission action of the corresponding pulleys 15 and belts 16, the corresponding two conveying rollers 13 rotate synchronously, so that the steel bars to be straightened can be conveyed. At the same time, in the process of straightening the steel bars, the vibration of the device can be reduced by the cooperation of the damper 21 and the spring 22, thereby improving the service life of the device.
