Description

Technical Field

[0001] The invention belongs to the technical field of bending devices, and in particular relates to a galvanized flat iron bending device. Background Art

[0002] During the construction of building mechanical and electrical equipment, the open grounding project of the electric shaft has strict requirements, and there are strict requirements on the bending parts of galvanized flat iron. During the construction process, the bending quality of galvanized flat iron is often poor. The common reasons are: laborers use simple tools to manually bend the flat iron, and often cannot control the bending angle well. At the same time, the labor intensity is high, which also affects the bending efficiency.

[0003] In order to solve the defects of manual flat iron bending by laborers, patent CN207606138U discloses a flat iron hydraulic bender, including a support plate, on which a hydraulic telescopic rod is fixedly connected. The utility model adds structures such as an installation box, a connecting rod and a first piston rod. The flat iron mold is an arc mold made according to actual needs. By controlling the hydraulic telescopic rod, the connecting rod moves close to the screw rod, and the two second pistons move close to each other through the first piston, so that the second piston rod is inserted into the through hole, the position of the screw rod is fixed, and the hydraulic telescopic rod is prevented from loosening when squeezing the screw rod, affecting the work efficiency. In addition, the second piston rod will cause the baffle rod to squeeze the support rod during the movement, so that the arc rod is inserted into the arc channel, further fixing the position of the screw rod, which is conducive to the bending of the flat iron. This new type uses hydraulic pressure to bend the flat iron, which significantly reduces the labor intensity and improves the construction efficiency, but it still cannot effectively control the angle of the flat iron bending, and there are also defects in the position control of the bending point of the bent flat iron.

[0019] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0020] A galvanized flat iron bending device, such as Figure 1 , 2 As shown, it includes a workbench 1, a pad 4, a fixed shaft 12, a sleeve 13, a pressure plate 14, a handle 15, a positioning mechanism, a first scale line 7, and a second scale line 3. The upper surface of the workbench 1 is provided with a fixed shaft 12 in the longitudinal direction. The fixed shaft 12 is rotatably connected with the sleeve 13. The outer surface of the sleeve 13 is connected to one end of the pad 4. The bottom end of the pad 4 is slidably connected to the upper end of the workbench 1. The upper end of the pad 4 is provided with a pressure plate 14 for squeezing and bending flat iron 18. The upper surface of the workbench 1 on one side of the pad 4 is provided with a positioning mechanism for fixing the flat steel. The positioning mechanism is provided with a first scale line 7 for measuring the bending position of the flat steel. The upper surface of the workbench 1 on the side of the fixed shaft 12 away from the starting position of the pad 4 is provided with a second scale line 3 for measuring the bending angle of the flat steel. The outer surface of the pressure plate 14 is fixedly connected with a handle 15.

[0021] like Figure 1 , 2As shown, the positioning mechanism includes an angle steel 6, and the pad 4 is a rectangular plate. In the initial position, one end of the rectangular plate abuts against the inner end of the angle steel 6, and the inner end of the angle steel 6 constitutes a limiting surface of the pad 4, that is, when the pad is rotated, as long as the end of the pad abuts against the limiting surface, it represents that the pad is in the initial position; the axis of the fixed shaft 12 is located in the vertical plane where the limiting surface is located, the bottom of the horizontal section of the angle steel 6 is connected to the upper surface of the workbench, the vertical section faces one side of the fixed shaft 12, and the vertical section 1 2 is provided with a first scale line 7 at the top, and the 0 scale line of the first scale line 7 is located in the vertical plane where the limit surface is located, that is, when determining the bending position, the right end of the flat steel is placed on the scale of the first scale line of the set length (such as bending at a distance of 10 cm from the right end of the flat steel, that is, aligning the right end of the flat steel with the 10 cm scale), and the position of the flat steel at the axis of the fixed shaft is the bending position, and the end of the pad 4 adjacent to the fixed shaft 12 is fixedly connected to the outer surface of the sleeve 13 through a connecting plate.

[0022] like Figure 1 , 2 As shown, a plurality of baffles 5 are arranged side by side on the upper surface of the workbench 1 opposite to the vertical section of the angle steel 6 along the direction of the angle steel 6. The inner surface of the baffle 5, the shaft sleeve 13, and the outer surface of the vertical section of the angle steel 6 together constitute a limiting structure for the flat steel 18 to be processed.

[0023] like Figure 1 , 2 As shown, the upper surface of the workbench 1 is provided with a second scale line 3 around the axis of the fixed shaft 12 for marking the bending angle of the angle steel. Figure 1 As shown, when bending the flat steel, place the flat steel 18 in the above-mentioned limiting mechanism, find the bending position, hold the handle and rotate the pressing plate 14 clockwise, and bend the flat steel to the set angle according to the indication of the second scale line 3.

[0024] like Figure 1 , 2 As shown, two straight grooves 17 are provided on the upper surface of the workbench 1 along a direction perpendicular to the angle steel 6, and the bottom end of the angle steel 6 is slidably connected to the straight groove 17 through a slider, and a telescopic mechanism is also provided on the upper surface of the workbench 1, and the fixed end of the telescopic mechanism is fixedly connected to the upper surface of the workbench 1, and the telescopic end is fixedly connected to the outer edge of the horizontal section of the angle steel 6.

[0025] like Figure 1 , 2 As shown, the telescopic mechanism is a cylinder 10, and the telescopic end of the cylinder 10 is fixedly connected to the middle of the horizontal section of the angle steel 6 through a connecting piece. The cylinder 10 pushes the angle steel 6 to fix the part of the flat iron 18 that does not participate in the bending between the vertical section of the angle steel and the baffle, ensuring that no displacement occurs during the bending process, so that no additional deformation occurs during the bending process of the flat iron.

[0026] like Figure 1 , 2 As shown, two rows of positioning holes 9 are provided on the upper edge of the pad 4 perpendicular to the direction of the pressure plate 14. The pressure plate 14 is screwed to the positioning holes 9 through positioning bolts 16. The distance between the positioning holes 9 and the shaft sleeve 13 is adapted to flat steel 18 of different thicknesses. When the thickness of the flat steel changes, the position of the pressure plate can be adjusted by connecting new positioning holes.

[0027] like Figure 1 , 2 As shown, the workbench 1 is provided with supporting legs 2 at the lower end and a control panel 11 for controlling the movement of the cylinder at the upper end. A plurality of stiffening ribs 8 are welded at the inner corners of the angle steel to ensure the structural strength of the angle steel itself and further ensure the fixing effect of the flat steel.
