UTILITY MODEL CONTENTS

[0003] The utility model aims at providing a simple on -the -spot reinforcing bar bender upper support structure, solving the problem that the cost is high when using a large bending machine to bend the reinforcing bar with a large radius, and when the reinforcing bar is bent by using the disc-shaped component welded by artificial welding, the disc-shaped component welded has the problem of irregular shape, which leads to poor bending effect and the problem that the load bearing capacity of the force bearing member is not strong when bending, and it is difficult to bend the reinforcing bar with large diameter specifications.

[0004] To achieve the above object, the utility model provides the following technical scheme:

[0005] A simple on -the -spot reinforcing bar bender upper support structure, comprising: base, fan ring component and stress column, the base with the fan ring component can be detachably connected, the base with the fan ring component all are fixedly connected with the stress column, the stress column quantity is several and each stress column to the base center point The distance is equal.

[0006] When the reinforcing steel bars of the bridge cast-in-place pile are bent, the radius of the reinforcing steel bar bending is large, and the ordinary bending machine is not good for operation in the face of such demand, so a large bending machine needs to be used, but the cost of reinforcing steel bar bending by using the existing large bending machine is high, and the on-site problem is usually solved by welding a disc-shaped component on the reinforcing steel bar bending machine turntable, but the disc-shaped component welded by manual welding has the problem of irregular shape, which leads to poor bending effect, and at the same time, since the force bearing piece is a single reinforcing steel bar during bending, the load bearing capacity is not strong, and it is difficult to bend the reinforcing steel bar with large diameter specifications. The upper support structure of the simple reinforcing steel bar bending machine on site provided by the utility model can be based on the traditional bending machine, and only by installing a support structure above the bending machine, the fan ring-shaped component on the support component is used as a force bearing piece, compared with the method of using reinforcing steel bars as force bearing pieces, the fan ring-shaped component has larger force bearing area and stronger load bearing capacity, so as to realize the large radius bending demand of the reinforcing steel bar and the demand of bending the reinforcing steel bar with large diameter specifications, and at the same time, the contact between the reinforcing steel bar and the force bearing piece during bending is changed from point-to-point contact to line-to-surface contact, so as to ensure uniform force and improve the bending effect. The force bearing column is used as a force bearing piece when bending the small diameter reinforcing steel bar, compared with the fan ring-shaped component, the force bearing column has simple structure and is easy to install, so as to meet the bending demand of the small diameter reinforcing steel bar and reduce the cost.

[0007] Further, the upper support structure of the simple reinforcing steel bar bending machine on site further comprises a clamping piece, the clamping piece is fixedly connected with the base, and the distance from the clamping piece to the center point of the base is greater than the distance from the force bearing column to the center point of the base.

[0008] When the reinforcing steel bar bending machine is used to bend the reinforcing steel bar, one end of the reinforcing steel bar to be bent needs to be fixed on the base, and the clamping piece is used to fix it, so as to ensure that the reinforcing steel bar can normally bend when the base rotates. The distance from the clamping piece to the center of the base is farther than the distance from the force bearing column to the center of the base, so as to ensure that there is space for storing the reinforcing steel bar between the clamping piece and the force bearing column.

[0009] Further, a plurality of connecting holes are evenly distributed on the base, and the clamping piece is fixedly connected with the base through the connecting holes.

[0010] In actual operation, the diameter specifications of the reinforcing steel bars to be bent are different, and the clamping piece is adjusted by opening a plurality of connecting holes on the base and connecting the clamping piece with the connecting holes, so as to meet the bending requirements of reinforcing steel bars with different diameter specifications.

[0011] Further, the force bearing columns are distributed at equal intervals.

[0012] In actual operation, the shape of the steel bar after bending may not meet the requirements of the actual working conditions due to uneven force. By setting force columns at equal intervals, the force on the steel bar during bending is ensured to be uniform and stable, and the shape of the steel bar after bending meets the requirements of the actual working conditions.

[0013] Further, the number of fan ring members is several.

[0014] In actual work, there are various forms of steel bar bending requirements, which may be right angle or circular. By adding or reducing the number of fan ring members, the steel bar can be bent into different shapes as required.

[0015] Further, the upper support structure of the simple steel bar bending machine further comprises a first support and a second support, the first support is fixedly connected with the base, the second support is detachably connected with the first support, and the second support is detachably connected with the fan ring member.

[0016] When bending a steel bar with a large diameter specification, the fan ring member bears a large load.

[0017] Further, the base is provided with a through fixing hole in the vertical direction, and the base is detachably connected with the steel bar bending machine through the fixing hole.

[0018] The upper support structure provided by the present application needs to rely on the existing steel bar bending machine for rotation, so the upper support structure is connected with the steel bar bending machine, and the upper support structure is connected with the rotating disc of the steel bar bending machine through the fixing hole. Compared with direct fixing connection such as welding or threaded connection, the connection and rotation of the support structure and the steel bar bending machine can be realized without affecting the normal use of the original steel bar bending machine, and the effect of convenient disassembly and assembly is achieved.

[0019] Further, the connection between the second support and the fan ring member is wedge-shaped.

[0020] By adopting the design of wedge-shaped joint, when the second support is stressed, in addition to the friction component of the joint surface, the remaining components are directed to the wider part of the wedge. Through the transmission of force, the component is transmitted to the first support, so that the first support, the second support and the fan ring member share the load borne by the support structure during the steel bar bending process, and the three main stressed components are uniformly stressed during the steel bar bending process to prevent some components from being damaged due to excessive load.

[0021] Further, the upper support structure of the on-site simple reinforcing bar bender further comprises a lifting ring, and the lifting ring is rotationally connected with the upper surface of the base.

[0023] Further, the base is provided with a groove for accommodating the lifting ring, and the lifting ring is attached to the groove bottom when rotated to the horizontal direction.

[0024] If the lifting ring is always in the vertical state, the lifting ring is easily collided by objects such as reinforcing bars and even damaged, the lifting ring is accommodated by the groove, damage of the lifting ring due to mechanical collision of other objects in daily use is avoided, and the service life of the lifting ring is improved.

[0025] The one or more technical solutions provided by the utility model have at least the following technical effects or advantages:

[0026] (1) The upper support structure of the on-site simple reinforcing bar bender can replace only the uppermost panel on the basis of the traditional bending machine, so that large-radius bending of reinforcing bars can be realized, and the effect of reducing cost is achieved without using a large bending machine.

[0027] (2) The utility model uses the fan ring member to replace the reinforcing bar stress member in the manual welding disc-shaped member for large-radius bending of reinforcing bars in the conventional mode, so that the contact between the reinforcing bar and the stress member during bending changes from point contact to surface contact, the stress is uniform, and the bending effect is improved.

[0028] (3) The fan ring member is used as the stress member during bending of the reinforcing bar, and is matched with the first support member and the second support member, the load borne by the fan ring member is shared based on the force transmission mode, compared with the mode of using the reinforcing bar as the stress member, the stress area of the fan ring member is larger and the load bearing capacity is stronger, and the bending demand of the large-diameter specification reinforcing bar can be met.

[0029] (4) The stress member of the reinforcing bar bending machine is set in the form of increase and decrease, so that various bending form demands are met, including but not limited to U-shaped, right-angle type and circular, and different working condition requirements are adapted.
