Description

Technical Field

[0001] This utility model relates to the field of bending device technology, specifically a bending device for round steel of different sizes. Background Technology

[0002] Round steel bending machines are common processing equipment on construction sites, mainly used to bend steel bars to facilitate later binding into cages.

[0003] Most of the round steel bending devices commonly found on the market are similar in overall structure. They are driven by a motor to rotate a turntable with two sets of stop shafts inserted on the turntable. Together with the stop shafts on the side limit frame, they can bend the round steel into shape. However, they have some functional shortcomings in actual use and have room for improvement. For example, the position of the side limit frame is generally fixed, which limits the bending of large components and does not provide a function to easily adjust the position of the side limit frame.

[0004] Now, a novel round steel bending device suitable for different sizes is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a round steel bending device suitable for different sizes, so as to solve the problem mentioned in the background art that it does not have the function of easily adjusting the side limit position.

[0007] The adjustment assembly includes four sets of limiting slide rails, which are fixedly connected to the front and rear ends of the top of the bottom box. The front and rear ends of the limiting slide rails are provided with multiple sets of limiting screw holes. A hand-tightening bolt is inserted into the front end of the limiting slide rail. The front and rear ends of the side limiting frame are fixedly connected to limiting sliders, and the limiting sliders are provided with internal threaded screw holes.

[0008] As a further technical solution of this utility model, the inner diameters of the limiting screw eye and the internal thread screw eye are the same, and the limiting screw eye penetrates the inner and outer surfaces of the limiting slide rail.

[0009] As a further technical solution of this utility model, the hand-tightening bolt passes through the interior of the limiting screw hole and the internal thread screw hole, and the external thread of the hand-tightening bolt matches the internal thread of the internal thread screw hole.

[0010] As a further technical solution of this utility model, the shape and size of the outer side of the limiting slider are adapted to the shape and size of the inner side of the limiting slide rail, and the limiting slider can slide left and right along the inner side of the limiting slide rail.

[0011] As a further technical solution of this utility model, a first electric cylinder is installed on the outer side of the side support frame, a concave frame is fixedly connected between the output ends of the two sets of first electric cylinders, a pressing roller is movably connected between the front and rear ends inside the concave frame, the first electric cylinders are symmetrically distributed about the vertical center line of the bottom box, and the PLC controller and the first electric cylinders are electrically connected.

Multiple sets of third limiting holes are opened at the bottom end of the pressing plate. The outer diameters of the turntable and the pressing plate are the same, and the positions and dimensions of the first limiting hole and the third limiting hole correspond one-to-one.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the round steel bending device applicable to different sizes not only realizes the function of easy adjustment of the side limit position, but also realizes the function of preventing the pressing tail end from tilting and swinging, and also realizes the function of preventing the pressing end from falling off.
