Detailed Description
As shown in fig. 1-3, a steel bar bending tool adaptable to steel bars of different specifications is used for bending metal wires including steel bars; including vertical setting, be prismatic reinforcing bar fixed column 1, reinforcing bar fixed column 1 lower extreme setting is in being arranged in limiting reinforcing bar fixed column 1 around the rotatory fixed basis of axis, and the upper end offers the reinforcing bar draw-in groove 11 that is used for cliping the reinforcing bar of treating buckling.
The reinforcing steel bar clamping groove 11 becomes wider gradually from bottom to top; thereby seizing reinforcing bars of different diameters. It is necessary to make the bar slot 11 deeper and steeper, otherwise the bar tends to fall out during bending.
The bearing 2 is sleeved on the steel bar fixing column 1, and the steel bar fixing column 1 is fixedly connected with the inner side surface of the bearing 2; a force arm adjusting plate 3 for adjusting a resistance arm when the steel bar is bent is horizontally anchored on the outer side surface of the bearing 2, a straight line which is crossed by the upper surface of the force arm adjusting plate 3 and the axis of the bearing 2 is marked as a force arm line, and a force application column 4 for driving the steel bar to be bent is detachably anchored on the force arm line; one end of the steel bar is clamped by the steel bar clamping groove 11, and then the force application column 4 drives the steel bar to bend.
The handle 5 is anchored on the side surface of the force arm adjusting plate 3, and the length direction of the handle 5 is arranged along the force arm line so as to effectively transfer torque.
The distance between the force application column 4 and the axis of the bearing 2 is a resistance arm, the distance between the end part of the handle 5 and the axis of the bearing 2 is a power arm, and when thicker steel bars need to be bent, the force application column 4 only needs to be moved to a position close to the bearing 2, so that larger bending force can be provided; when the thin steel bar needs to be bent, the force application column 4 only needs to be moved to a position far away from the bearing 2, so that the bending can be completed by a short distance, and the bending efficiency is improved.
In this embodiment, bolt holes are formed in the upper surface of the moment arm adjusting plate 3 at intervals along the moment arm line, and the force application column 4 is a bolt vertically inserted into one bolt hole. This allows the bolts to be inserted in different bolt holes to vary the length of the resistance arm.
The bearing 2 is annular, and the edge of the upper surface of the bearing 2 is provided with angle scales 21 which surround the bearing 2 for a circle. In the angle scale 21, from the same starting point, a small scale 21 is set every 15 degrees, a medium scale 21 is set every 30 degrees, and a large scale 21 is set every 90 degrees. During construction, the bending angles of the steel bars are most commonly 30, 60, 90, 120 and 135 degrees, and the scale 21 lines arranged in the way meet the common bending angles and can be uniformly distributed at the same time. As shown in fig. 2 to 3, in the present embodiment, since the bending angle of the reinforcing bar is 30, 60, 90, 120, the small scale 21 and the large scale 21 are not provided.
The fixed foundation can be a concrete base or a hardened ground, and the lower end of the steel bar fixing column 1 is tightly inserted into a hole on the concrete base or the hardened ground. Concrete foundations or hardened floors are common on construction sites. If the condition is satisfied, for example, in a prefabrication field, the fixed foundation can also be selected to be a bench clamp which tightly clamps the lower end of the steel bar fixing column 1. This eliminates the need to perforate the ground.
Connecting blocks 12 are plugged between the side vertical surfaces of the steel bar fixing columns 1 and the inner side surfaces of the bearings 2, and the connecting blocks 12 are respectively connected with the steel bar fixing columns 1 and the bearings 2 in a welding mode so as to reinforce the connection strength of the steel bar fixing columns 1 and the bearings 2.
The free end of the handle 5 is sleeved with an anti-slip rubber sleeve for convenient holding.
The utility model relates to a steel bar bending tool capable of adapting to steel bars with different specifications, which comprises the following steps in the using process:
the method comprises the following steps: fixing the lower end of the steel bar fixing column 1 so that the steel bar fixing column cannot rotate around the central axis of the steel bar fixing column;
