Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence between the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.

As shown in fig. 1, the reinforcing bar bending tool provided in this embodiment includes a fixing base 1 and a torque wrench 2.

One end of the fixed seat 1 is a butting edge 11, and the other end of the fixed seat is provided with a hinge point 12. The abutment edge 11 is intended to abut against a prefabricated element 10 (as shown in fig. 2).

The torque wrench 2 is connected to the hinge point 12, so that the torque wrench 2 rotates relative to the fixing base 1 through the hinge point 12. When the torque wrench 2 rotates, in order to ensure the maximum rotation stroke and avoid interference, the external dimension (i.e. the projected area of fig. 1) of the fixing base 1 gradually increases from the position close to the torque wrench 2. For example, the shape of the fixing base 1 can be designed as an equilateral triangle, the abutment edge 11 is the base of the triangle, and the hinge point 12 is adjacent to the vertex of the triangle.

The fixing seat 1 is convexly provided with a middle limit stop 13 and two edge limit stops 14. The length of the middle bump stop 13 extends in a direction perpendicular to the abutment edge 11 and in the direction of the torque wrench 2. Namely, the middle bump stopper 13 coincides with the height of the triangle (the central axis of the fixing base).

Limit stop 14 of limit portion's effect increases the area of contact between fixing base 1 and the prefabricated component 10, increases frictional force and reduces to make fixing base 1 laminate tighter, few instrument dislocation when buckling the reinforcing bar. Therefore, the edge stopper 14 may be provided on the side of the holder 1 or may not be provided on the side. Two limit stop 14 of limit portion is the relative setting with butt limit 11 parallel and level. The edge limit stopper 14 is provided with a chamfer 141 on the edge adjacent to the middle limit stopper 13, and the chamfer adjacent to the torsion wrench 2 is larger than the chamfer adjacent to the prefabricated part 10, so as to avoid interference when bending the steel bar.

The torque wrench 2 includes a handle 21, a torque head 22, a middle bending stop 23 and an edge bending stop 24. The twisting head 22 is connected to the hinge point 12, and the twisting head 22 includes a triangular portion 221 and a hinge portion 222 disposed at one end of the triangular portion 221. The material removal processing is performed on the hinge portion 222 through an arc, so that the area of the hinge portion 222 is smaller than that of the triangular portion 221, which is beneficial for connecting the hinge portion 222 with the hinge point 12. The end of the triangular part 221 away from the hinge point 12 is integrally connected with the handle 21.

The middle bending stop 23 is arranged on the central axis (vertical height line) of the triangular part 221, and two side bending stops 24 are respectively arranged on two sides of the triangular part 221 close to the hinge part 222. The two edge bending stoppers 24 are oppositely arranged. The inner side surface of the edge bending stop block 24 is provided with a groove matched with the steel bar, the groove enables the protruding edge of the edge bending stop block 24 to be formed with a flange, and when the steel bar is arranged in the groove, the steel bar is twisted under the limiting action of the flange, so that the transmission of the twisting force is facilitated.

The fixing base 1 includes a first side surface (not numbered) and a second side surface (not numbered) which are oppositely arranged, and may be defined as: the first side is the front of the fixing base 1, and the second side is the back. The middle limit stop is positioned on the first side surface, and the torsion wrench 2 is hinged to the fixed seat 1 on the second side surface. In this way, interference in the rotation of the torque wrench 2 can be avoided.

In this embodiment, the edge bump stopper 14 and the middle bump stopper 13 are both located on the same side (first side) of the fixing base 1.

The middle bending stopper 23 and the side bending stopper 24 are both located on the same side (the first side) of the torque wrench 2, that is, the protruding extending directions of the middle limit stopper 13, the side bending stopper 24, and the middle bending stopper 23 are the same. The protruding direction of the edge stopper 14 may be set to be the same.

As shown in fig. 2 and 3, when the reinforcing bar bending tool is used, the abutting edge 11 of the fixing seat 1 is firstly tightly attached to the surface of the prefabricated part 10, and the middle limit stopper 13 is abutted to the reinforcing bar 20 to be bent (if the reinforcing bar needs to be bent upwards, the lower end surface of the middle limit stopper 13 is abutted to the reinforcing bar, and if the reinforcing bar needs to be bent downwards, the reinforcing bar returns to a straight state, the upper end surface of the middle limit stopper 13 is abutted to the reinforcing bar).

The handle 21 is rotated and pressure is applied to the direction of the prefabricated part 10, so that the fixed seat 1 is attached without dislocation. The handle 21 is rotated to move the twisting head 22 together. The reinforcing bars 20 are bent upward by the edge bending stoppers 24. The bent reinforcing steel bar can be recovered by reversely rotating in the method. The bending action can also be achieved by means of a middle bending stop 23.

And operating the handle, bending the steel bar to a preset position, and performing one-step forming on the bent steel bar. The reinforcing steel bar bending tool can realize 0-180-degree bending.

The reinforcing bar instrument during operation of buckling only needs limit portion buckle dog 24 with the contact of reinforcing bar 20 can, need not the exhibition flat spanner 2 that twists reverse, consequently, should buckle the instrument and can realize stretching out the adjustment such as the buckle, the alignment of reinforcing bar in narrow and small space operation, convenience simple to use, reinforcing bar adjustment one shot forming, efficiency is higher.

The middle limit stop 13 plays a supporting role in the non-bending part of the steel bar when the steel bar is bent and flattened.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
