Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment processing technology, and in particular relates to a thin steel plate bending device for air compressor maintenance. Background Technology

[0002] Announcement No. CN208643733U discloses a utility model patent for a thin steel plate bending tool, comprising a base and a pressure plate. The upper part of the base is welded into a U-shape by L-shaped angle steel, with an L-shaped angle steel serving as a limiting plate above one edge, 1-2 cm away from the top of the base. The opening of the limiting plate faces downward. The pressure plate includes a pressure strip formed by L-shaped angle steel and a handle welded to the pressure strip. The length of the handle is more than ten times the width of the pressure strip. The pressure strip connects to the base and the limiting plate. One end is connected by a hinge, allowing the pressure strip to rotate along the hinge axis until it is parallel to one side of the limiting plate and maintains a distance of 1-3mm. A ruler perpendicular to the limiting plate is also provided on the top of the base, with its zero mark aligned with the end of the limiting plate closest to the hinge, and the mark extending further away from the hinge. A protractor is also provided on the base at the other end of the limiting plate, with its center collinear with the hinge axis and its zero mark horizontal. A pointer is provided on the pressure strip; when the pressure strip is horizontal, the pointer points to the zero mark. This design simplifies the structure, makes it easy to use, and reduces costs.

[0003] However, this patent also has some defects in its use. The height of the limiting plate is fixed and cannot be adjusted according to the thickness of the thin steel plate. If the thin steel plate being bent is too thin, there will be a large gap between the thin steel plate and the limiting plate, which will cause errors when bending the thin steel plate. In addition, the patent does not have a device to fix the thin steel plate, which will reduce the bending accuracy when bending the thin steel plate. Utility Model Content

A first positioning plate 51 and a second positioning plate 52 are threadedly connected to the threaded rod 5. A connecting plate is sleeved on the threaded rod 5 between the first positioning plate 51 and the second positioning plate 52. The connecting plate is fixed at both ends of the limiting plate 2.

[0020] The positioning assembly includes a U-shaped fixing plate 4 fixed on the worktable 1. A positioning plate 6 is set inside the frame of the fixing plate 4. Sliding rods 42 are fixed on both sides of the upper end of the positioning plate 6. The sliding rods 42 are slidably connected to the fixing plate 4. An adjusting rod 41 is threadedly connected to the fixing plate 4 between the two sliding rods 42. A rotating block is fixed at the bottom of the adjusting rod 41. The rotating block is fixedly connected to the positioning plate 6. A pad 11 is fixed at the upper end of the worktable 1. The pad 11 is flush with both ends of the worktable 1.

[0021] The bending assembly includes two hinges 7 fixed to one end of the workbench 1. The hinges 7 and the limiting plate 2 are located on the same side.

A handrail 31 is fixed to the bottom of the horizontal side of the pressure plate 3.

[0022] Working principle: During use, the operator adjusts the limiting plate 2 according to the thickness of the thin steel plate to be bent. After the limiting plate 2 is adjusted to a suitable height, the thin steel plate is placed in the gap between the limiting plate 2 and the pad 11. Then the limiting plate 2 is lowered to contact the thin steel plate. The connecting plate is fixed by the first positioning plate 51 and the second positioning plate 52.
