Abstract
The invention provides a portable round steel bending device. A body structure is formed by a high-pressure oil cylinder, a support, pull rods, hanging basket screws and the like. Auxiliary facilities are not needed. The stretching part of round steel, with the diameter phi ranging from 10 mm to 30 mm, embedded in a high-rise building can be bent through operation of one person, a reinforced concrete structure is not damaged at all, and the portable round steel bending device can further replace an existing common pipe bending machine for mass machining on common occasions. The bending device is simple and practical in structure, low in manufacturing cost, light, large in load, capable of saving energy and labor and convenient to use, and thus an ideal equipment choice is provided for building construction.
Description
Technical field
The invention belongs to tooling auxiliary tool category.Specifically a during Construction of High-rise of construction site, the round steel extending area be embedded in reinforced concrete structure is carried out to the device of bending.
Background technology
Existing building is all reinforced concrete high-rise structures, need to carry out multiple angles to a large amount of plurality of specifications round steel in construction to bend, wherein bend very difficult again to the round steel extending area be embedded in reinforced concrete structure, the bending power applied when round steel bending is difficult to the xoncrete structure performance ensureing to have poured into a mould, and existing various bending equipment all can not adapt to special restriction and the demand of job site completely.
As large hydraulic bender, medium-sized mechanical bender etc., because volume is comparatively large, affiliated facility is many, and quality is large, can not adapt to the demand of high-rise narrow space site operation.
For another example small-sized bending machine class, because himself there being the firmly strong point, can not the displacement along with the workpiece by bending, be also not suitable with the demand to the bending again of built-in fitting in construction.
Summary of the invention
For the weak point that existing bending is equipped, the present invention devises a kind of Portable round bar bending machine, the demand of construction site site operation can be adapted to completely, especially the needs pre-buried ￠ 10mm ~ ￠ 30mm round steel being carried out to bending are once again achieved, for construction provides a kind of desirable lectotype selection.
Design of the present invention: during tall and big tier building construction, armored concrete is formation of casting several times, its interval time is very short, and the reserved extension of the round steel in Transducers Embedded in Concrete bends, to meet the technical requirement of next procedure by on-the-spot normal needs once again.Now, concrete solidifies not yet completely, and the active force applied when must guarantee bending can not have any damaging influence to concrete.This just requires: one, can not use jerk power; Two, traction force can not be had to the part in the Transducers Embedded in Concrete of round steel; Three, work high above the ground, narrow field to be met, there is no the features such as auxiliary power.Given this, the present invention is simple, short and small, light weight, without impulsive force, people's manual manipulation, can carry out the bending of arbitrarily angled and arc to ￠ 10mm ~ ￠ 30mm round steel continuously, meet the special requirement of job site completely.The domestic report that there is not yet technical scheme relevant with it at present.
Technical scheme of the present invention:
High pressure manual oil cylinder (1) is customed product, no matter perpendicularly to put, horizontal, inversion, all do not affect serviceability, maximum load 5T, pinch roller (6) is equipped with in piston rod (13) front end, cylinder body, with external screw thread, can in the screw hole of precession support (4), play a part to connect and regulate to coordinate distance.
Have concave groove on the upside of support (4) two ends, to hang pull bar (5), the two is round and smooth contact, fills angle change perhaps.
Support roller (7) and hanging basket screw (9), be contained on the bolt hole (12) of pull bar (5) lower end by bolt (8).Thus constitute simple and practical Portable round bar bending machine, whole deadweight is less than 7.5kg.
Described pinch roller (6) one and support roller (7) two are a grip assembly, and the crank slot contacted with round steel by it is divided into 10mm, 12mm, 16mm, 20mm, 24mm, 30mm meter 6 cover, for choosing dress during operation.
Described hanging basket bolt (9), rotatable adjustment length, so as to the spacing of adjustment pull bar (5), is bent to make round steel (10) arc varied in size.
The piston rod (13) of described oil cylinder (1), by adjustment collapsing length, adjusts the spacing of hanging basket bolt (9) simultaneously, is bent to make round steel (10) angle varied in size.
The piston rod (13) of described oil cylinder (1), by adjustment collapsing length, adjusts the spacing of hanging basket bolt (9) simultaneously, round steel (10) can be made to be bent into different angles and arc.
The present invention has following features and advantage:
Simple and practical, cost is low, and deadweight is no more than 7.5kg, is easy to carry
Load is maximum reaches 5T, is convenient to bend ￠ 30mm and following round steel (10)
Volume is short and small, suitable high-rise narrow space one-man service.
Manual hand manipulation, without the need to other auxiliary equipment, energy-conservation saving of labor.
Alternative general elbow machine uses.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described, do not limit the present invention.
Example 1, wide space, the bending ￠ 20mm round steel (10) of batch becomes R arc 90 ° of angles: first choose suitable pressure, supporting roller component loads this bending machine, and adjust hanging basket screw (9) to suitable interval, then required round steel (10) is placed between pinch roller (6) and support roller (7), then upper and lower pressure-raising handle (2) repeatedly, piston rod (13) stretches out gradually, round steel (10) is forced to bend with brute force, open pressure relieving valve (3), direct hand returns the piston rod (13) stretched out, take out bending round steel (10), then put second round steel again to exert pressure, circulation like this, complete batch production, namely the situation shown in Fig. 2.
Example 2, wide space, the bending ￠ 30mm round steel of batch becomes nature R arc 130 ° of angles.First choose suitable pressure, supporting roller component loads this bending machine, and remove hanging basket screw (9) and do not assemble, all the other methods of operating are same as Example 1, just stop pressing when R arc 130 ° of angles and open pressure relieving valve (3), i.e. situation shown in Fig. 3.
Example 3, high-rise narrow space, the extension reserved to pre-buried ￠ 16mm round steel (10) bends to R arc 70 ° of angles.First choose suitable pressure, supporting roller component loads this bending machine, and adjust the spacing of hanging basket screw (9), be inserted in bending machine from the top of pre-buried round steel; Or bending machine is assembled in the relevant position of round steel (10), then manual pressure, along with the yield deformation of round steel (10), also there is relevant position change in bending machine, without any vibratory impulse power and involve power, during to 70 ° of angles; I.e. situation shown in Fig. 2.Open pressure relieving valve (3), return the piston rod (13) stretched out with hand, and take down bending machine, be then inserted in next root round steel and continue to repeat, complete small lot job execution.
