When the steel bar bending machine is powered on, the feeding motor rotates, the upper guide wheel rotates the steel bar to move, and the lower guide wheel is pressed by the spring to press the steel bar. When the steel bar is fed to the specified position, the bending motor rotates forward to bend the steel bar, the motor reverses the worktable and resets, and the electric steel bar cutter completes a bending task. Main device design: (1) Steel bar feeding and pressing mechanism When the steel bar is fed in, the lower guide wheel is positioned by the screw nut mechanism to the designated position and then pressed by the spring under the action of the spring. After pressing the steel bar, the feeding motor rotates to make the lower guide wheel rotate, which has the power to move the steel bar forward, so as to realize the process of feeding the steel bar. (2) Rebar bending mechanism The mechanism drives the turntable to rotate through the motor, and the turntable is provided with a blocking post. When the turntable rotates, the blocking post blocks the steel bar so as to realize the bending process of the steel bar.

Road roller is a type of construction machinery that is widely used at present, and it is also a kind of engineering equipment often used in pavement engineering. However, many people do not know much about the working principle of road rollers, so what is the working principle of road rollers? Today I will show you all about it. 1. The road roller is suitable for various compaction operations by the gravity of the machine itself, so that the rolled layer will be permanently deformed and compacted. There are two types of road rollers: steel wheel type and tire type. 2. The road roller, also known as the soil compactor, is a kind of equipment for road construction. Road rollers belong to the category of road equipment in construction machinery, and are widely used in the filling and compaction of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, stadiums, etc. Subgrade stabilized soil and asphalt concrete pavement layer. 3. The road roller is a method of using mechanical weight and vibration to repeatedly load the compacted material to overcome the cohesion and internal friction between the materials. 4. It is an operation machine that removes the gas and water inside it, forces the displacement between the material particles, wedges each other tightly, increases the density, and makes it reach a certain degree of density and flatness. The above is the working principle of the road roller shared by the editor. I believe that after reading the above article, you have a certain understanding of the working principle of the road roller, and interested friends can learn about it.
