Description

A kind of Portable round bar bending machine
Technical field
The utility model belongs to tooling auxiliary tool category.Specifically a during Construction of High-rise of construction site, the device that bending is carried out in the round steel extending area being embedded in reinforced concrete structure.
Background technology
Existing building is all reinforced concrete high-rise structures, in construction, need a large amount of plurality of specifications round steel to carry out multiple angles bending, wherein to being embedded in round steel extending area in reinforced concrete structure, to carry out bending more very difficult, the bending power applying when round steel bending is difficult to the xoncrete structure performance that assurance has been poured into a mould, and existing various bending equipments all can not adapt to particular restriction and the demand of job site completely.
As large hydraulic bender, medium-sized mechanical bender etc., because volume is larger, 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 be along with by the workpiece of bending and displacement, be also not suitable with in construction the demand of bending again of built-in fitting.
Utility model content
Weak point for existing bending equipment, the utility model has designed a kind of Portable round bar bending machine, the demand that can adapt to construction site site operation completely, especially the needs that pre-buried ¢ 10mm~¢ 30mm round steel is carried out to bending have once again been realized, for construction provides a kind of desirable lectotype selection.
Design of the present utility model: during tall and big tier building construction, armored concrete is to cast several times to form, its interval time is very short, on-the-spot often the reserved extension of the round steel in Transducers Embedded in Concrete need to be carried out crooked once again, to meet the specification requirement of next procedure.Now, concrete solidifies not yet completely, and the active force applying in the time of must guaranteeing bending can not have any damaging influence to concrete.This just requires: one, can not use jerk power; Two, to the part in the Transducers Embedded in Concrete of round steel, can not there is traction force; Three, to meet work high above the ground, narrow field, there is no the features such as auxiliary power.Given this, the utility model is simple, short and small, light weight, without impulsive force, people's manual manipulation, can be continuously carry out arbitrarily angled and bending arc to ¢ 10mm~¢ 30mm round steel, has met the special requirement of job site completely.The current domestic report that there is not yet relevant with it technical scheme.
The technical solution of the utility model:
High pressure manual oil cylinder (1) is customed product, no matter perpendicularly put, horizontal, inversion, all do not affect serviceability, maximum load 5T, piston rod (13) front end is equipped with pinch roller (6), cylinder body is with external screw thread, can the screw hole of precession support (4) in, play a part to connect and regulate and coordinate distance.
Support (4) two ends upside has concave groove, and to hang pull bar (5), the two is round and smooth contact, fills angle perhaps and changes.
Support roller (7) and hanging basket screw (9), be contained in by bolt (8) on the bolt hole (12) of pull bar (5) lower end.Formed thus simple and practical Portable round bar bending machine, whole deadweight is less than 7.5kg.
(7) two of (6) one of described pinch rollers and support rollers are a grip assembly, and the crank slot contacting with round steel by it is divided into 10mm, 12mm, 16mm, 20mm, 24mm, 30mm meter 6 covers, choosing dress during for operation.
Described hanging basket bolt (9), rotatable adjustment length, so as to adjusting the spacing of pull bar (5), so that round steel (10) is bent to the arc varying in size.
The piston rod (13) of described oil cylinder (1) by adjusting collapsing length, is adjusted the spacing of hanging basket bolt (9), so that round steel (10) is bent to the angle varying in size simultaneously.
The piston rod (13) of described oil cylinder (1) by adjusting collapsing length, is adjusted the spacing of hanging basket bolt (9) simultaneously, can make round steel (10) be bent into different angles and arc.
The utlity model has following features and advantage:
Simple and practical, cost is low, and deadweight is no more than 7.5kg, is easy to carry
Load maximum can reach 5T, is convenient to ¢ 30mm and following round steel (10) to carry out bending
Volume is short and small, suitable high-rise narrow space one-man service.
Operation manually, without other auxiliary equipment, energy-conservation saving of labor.
Alternative general elbow machine uses.
Accompanying drawing explanation
Fig. 1, Portable round bar bending machine structural representation, label: 1, high-voltage oil cylinder, 2, handle 3, pressure relieving valve, 4, support, 5, pull bar, 6, pinch roller, 7, support roller, 8, bolt, 9, hanging basket screw, 10, round steel, 11, nut, 12, bolt hole, 13, piston rod
Fig. 2, during assembling hanging basket screw, round steel is by bending situation.
Fig. 3, during unassembled hanging basket screw, round steel is by bending situation.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described further, do not limit the utility model.
Example 1, wide space, crooked ¢ 20mm round steel (10) becomes 90 ° of angles of R arc in batches: first choose suitable pressure, supporting roller component packs this bending machine into, and adjust hanging basket screw (9) to suitable interval, then required round steel (10) is placed between pinch roller (6) and support roller (7), follow repeatedly upper and lower pressure-raising handle (2), piston rod (13) stretches out gradually, with brute force, force round steel (10) bending, open pressure relieving valve (3), directly with hand, return the piston rod (13) stretching out, take out crooked round steel (10), then putting second round steel exerts pressure again, so circulation, complete batch production, it is the situation shown in Fig. 2.
Example 2, wide space, crooked ¢ 30mm round steel becomes 130 ° of angles of nature R arc in batches.First choose suitable pressure, supporting roller component packs this bending machine into, and removes hanging basket screw (9) and does not assemble, all the other methods of operating are same as Example 1, just when 130 ° of angles of R arc, stop pressing and open pressure relieving valve (3), i.e. situation shown in Fig. 3.
Example 3, high-rise narrow space, bends to 70 ° of angles of R arc to the pre-buried reserved extension of ¢ 16mm round steel (10).First choose suitable pressure, supporting roller component packs this bending machine into, and adjusts the spacing of hanging basket screw (9), from the top of pre-buried round steel, is inserted in bending machine; Or bending machine is assembled in to the relevant position of round steel (10), manual pressure then, along with the yield deformation of round steel (10), relevant position also occurs bending machine changes, without any vibratory impulse power with involve power, during to 70 ° of angles; Be situation shown in Fig. 2.Open pressure relieving valve (3), with hand, return the piston rod (13) stretching out, and take down bending machine, be then inserted in next root round steel and continue to repeat, complete small lot job execution.
