Description

Technical Field

[0001] The utility model relates to the technical field of steel bar straightening machines, and specifically relates to a steel bar straightening machine for construction engineering. Background Technique

[0002] The steel bar straightening machine is also called a "steel bar stretching machine". It is a machine device specifically used for steel bar processing. The main function of the steel bar straightening machine is to straighten the coiled steel bars to meet the requirements of building construction.

[0003] At present, when some steel bar straightening machines are in use, they can straighten the steel bars, and a vertical plate is arranged on one side of the straightening roller. Openings are formed on the surface of the vertical plate. During the straightening process of the steel bars, one end of the steel bar passes through the opening, and the end far away from the steel bar straightening machine is prone to rotate greatly during the straightening process. At this time, the rotating steel bar is easy to cause harm to the surrounding workers. Therefore, the safety of some current steel bar straightening machines during use is relatively poor; in addition, if one end of some steel bars is bent greatly away from the steel bar straightening machine, when this end approaches the steel bar straightening machine, it is easy to pass through the other openings and affect the normal progress of the steel bar straightening operation.

[0026] The covering mechanism 10 includes a vertical rod 101, a lower arc plate 102 and an upper arc plate 103. The vertical rod 101 is fixedly connected to the top of the support plate 9. The lower arc plate 102 is fixedly connected to the top of the vertical rod 101. The number of the upper arc plates 103 is two. The two upper arc plates 103 are respectively hinged to the surfaces on both sides of the lower arc plate 102. A connecting rod 11 is fixedly connected to the surface of the upper arc plate 103. The arrangement of the connecting rod 11 can facilitate the staff to rotate the two upper arc plates 103 simultaneously. A rectangular groove is provided on the surface of the upper arc plate 103. After the upper arc plate 103 rotates, it cooperates with the lower arc plate 102 to limit the steel bar by covering.

[0027] The moving mechanism 13 includes a square plate 131, a moving plate 132, a rectangular rod 133 and a first compression spring 134. The surface of the square plate 131 is in contact with the inner wall of the storage box 12. A moving groove is formed in the top of the storage box 12. The moving plate 132 is fixedly connected to the top of the square plate 131, and the surface of the moving plate 132 is in contact with the inner wall of the moving groove.

The two ends of the first compression spring 134 are respectively fixedly connected to the inner wall of the storage box 12 and the surface of the square plate 131. When an operator presses the moving plate 132, the rectangular rod 133 can be driven to move through the square plate 131. Subsequently, the rectangular rod 133 moves under the action of the elastic force of the first compression spring 134 and contacts the inner wall of the rectangular groove, so as to fix the position of the upper arc plate 103. Accordingly, the steel bars can be covered by the cooperation of the lower arc plate 102 and the vertical rod 101, so as to reduce the situation that the steel bars rotate greatly.

[0028] The positioning mechanism 15 includes a hollow cylinder 151, a positioning rod 152 and a second compression spring 153. The hollow cylinder 151 is fixedly connected to the top of the bottom plate 14. The surface of the positioning rod 152 is slidably connected to the inner wall of the hollow cylinder 151. The second compression spring 153 is arranged inside the hollow cylinder 151. The two ends of the hollow cylinder 151 are respectively fixedly connected to the bottom of the inner wall of the hollow cylinder 151 and the bottom of the positioning rod 152. A positioning groove is formed in the top of the fixed box 5. The surface of the positioning rod 152 is in contact with the inner wall of the positioning groove. The guide block 17 is fixedly connected to the surface of the positioning rod 152. The position of the bottom plate 14 can be restricted by the cooperation of the positioning rod 152 and the positioning groove. Accordingly, the positions of the cross plate 7, the thin plate 8 and the support plate 9 can be fixed.

[0029] Working principle: First, the staff selects a suitable opening according to the size of the steel bar. After that, the staff can adjust the position of the covering mechanism 10 according to the position of the opening. In this process, the staff can first press the pressing plate 19, and the L-shaped rod 18 drives the positioning rod 152 to descend through the guiding block 17. At this time, the second compression spring 153 is stressed and shortened. Then, after the staff moves the support plate 9 to an appropriate position, the pressing on the pressing plate 19 can be released. After that, under the action of the elastic force of the second compression spring 153, the positioning rod 152 rises and can cooperate with the corresponding positioning groove to fix the position of the support plate 9. In this process, the back plate 23 drives the baffle 24 to move, and the baffle 24 can block the unused openings. Finally, after the staff places the steel bar inside the lower arc plate 102, the movable plate 132 can be pushed. At the same time, the staff rotates the upper arc plate 103. After that, under the action of the elastic force of the first compression spring 134, the rectangular rod 133 moves and cooperates with the rectangular groove to fix the position of the upper arc plate 103. At this time, the lower arc plate 102 and the upper arc plate 103 cooperate to fix the steel bar. One end of the steel bar passes through the through groove and the opening and can be straightened through the straightening roller 2. The use of the straightening roller 2 is a mature existing technology and will not be elaborated here.
