Description

Technical Field

[0001] This utility model relates to the field of square column buckle straightening processing technology, specifically a straightening machine with good straightening effect. Background Technology

[0002] Square column buckles are fasteners used in building formwork support systems. They are mainly used to fix and connect square columns (square steel pipes) to ensure the stability and load-bearing capacity of the formwork. They are widely used on construction sites, especially in the construction of cast-in-place concrete structures. In order to avoid the impact of bending or deformation of square column buckles on construction quality and safety, they need to be straightened by a straightening machine. The straightening process of square column buckles refers to correcting the square column buckles to restore them to a straight state.

[0003] However, during the straightening process, the square buckle needs to be placed on the tray first, and then the extension and retraction of the hydraulic cylinder output shaft drives the pressing block to press the bent part of the square buckle. Due to the smooth surface of the tray, the square buckle is very easy to slide on the tray after contacting the pressing block. The sliding square buckle will cause the position to shift, and the displaced square buckle will interfere with the straightening position. In order to strengthen the stability of the square buckle during the straightening process, the operator needs to hold the square buckle by hand. This method of strengthening the square buckle not only increases the workload of the operator, but also brings the contact distance between the straightening machine and the operator closer, thereby increasing the risk to the operator when straightening the square buckle.

A dual-axis motor 22 is fixedly installed on the inner end of the second ball screw 902, and a second reducer is installed on the output shaft of the dual-axis motor 22. The second reducer adjusts the speed of the output shaft of the dual-axis motor 12. A housing 23 located below the pressing block 10 is fixedly connected to the outer wall of the dual-axis motor 12.

[0029] Please see Figure 4 , Figure 8 and Figure 9 A hydraulic cylinder 12 is fixedly installed on the upper end face of the pressing block 10. A bracket 13 located above the pressing block 10 is fixedly connected to the lower end of the hydraulic cylinder 12. The bracket 13 is installed to connect the base 14 and the hydraulic cylinder 12. The base 14 located outside the sleeve 8 is fixedly installed at the lower end of the bracket 13, and the inner wall of the base 14 is fixedly connected to the outer wall of the housing 23.

[0030] The outer wall of the inner end of the telescopic rod 11 is evenly distributed with sliders 19, and the end of the slider 19 away from the telescopic rod 11 is slidably connected to the inner wall of the sleeve 8. The movement of the slider 19 inside the sleeve 8 strengthens the stability of the telescopic rod 11's telescopic movement inside the sleeve 8. A disc 20 is fixedly installed on the outer end of the telescopic rod 11, and a support rod 21 is fixedly connected to the upper end of the disc 20. The end of the support rod 21 away from the disc 20 is fixedly connected to the lower end face of the tray 2.

[0031] Working principle: In use, first, turn on the power of the dual-axis motor 22. After the dual-axis motor 22 is turned on, it drives the rotation of the second ball screws 902 on both sides. Due to the threaded connection between the second ball screw 902 and the second ball nut 901, the second ball screw 902 rotates in a circular motion while driving the second ball nut 901 to move horizontally. At the same time, the movement of the second ball nut 901 drives the telescopic rod 11 to extend and retract at the sleeve 8 through the connection of the connecting rod 903. The movement of the telescopic rod 11 drives the movement of the left and right trays 2 through the connection of the disc 20 and the support rod 21. When the trays 2 move to the appropriate position, the power of the dual-axis motor 22 can be turned off. Then, place the square column buckle body 1 on the left and right trays 2 and turn on the power of the rotary motor 17. The turning on of the rotary motor 17 drives the rotation of the first ball screws 402 on both the front and rear sides through the connection of the rotating shaft 16. The outer wall of the lead screw 402 is provided with threads in opposite directions, and the first ball screw 402 and the first ball nut 401 are connected by a threaded connection. This allows the first ball screw 402 on both the front and rear sides to rotate circumferentially, while simultaneously driving the first ball nut 401 on its surface to move towards the square column buckle body 1. As the first ball nut 401 moves, it drives the clamping plate 3 to move towards the square column buckle body 1 through the connection of the vertical rod 15, until the rubber pad 7 on the clamping plate 3 clamps the outer wall of the square column buckle body 1. Then, the power of the rotary motor 17 is turned off. Subsequently, the power of the electric push rod 6 is turned on, and the extension of the internal output shaft of the electric push rod 6 drives the pressure plate 5 to press the square column buckle body 1, thereby strengthening the stability of the square column buckle body 1 during the straightening process. Finally, the power of the hydraulic cylinder 12 is turned on, and the extension of the internal output shaft of the hydraulic cylinder 12 drives the pressing block 10 to move towards the square column buckle body 1, thus performing the straightening process on the square column buckle body 1.
