Abstract

The utility model discloses a steel bar bender. The steel bar bender is particularly composed of a flexural center grinding head, a roller mechanism and a hydraulic cylinder with the fixed position. The flexural center grinding head is detachably connected to a pushing rod of the hydraulic cylinder. The side, opposite to the pushing rod, of the flexural center grinding head is a semicircular arc face. The flexural center grinding head has a selectable arc face diameter set corresponding to the standards and materials of steel bars to be bent. The roller mechanism comprises a roller cushion plate with multiple inserting holes and two rollers. The two rollers are distributed and inserted into the inserting holes in a mirror symmetry mode about the axis of the pushing rod of the hydraulic cylinder. The flexural center grinding head is driven by the hydraulic cylinder to abut against the steel bars between the two rollers in a forward and backward mode. The steel bar bender has the advantages that bending capacity is high and the steel bars with high strength are easily bent; the bending radius is changeable, each component can be adjusted and replaced, the application range is wide, and the steel bar bender is suitable for bending the steel bars of various standards; operation is simple, safety performance is good, and the steel bar popup probability is small when the steel bars are bent.

Description

A kind of angle-bender
Technical field
The utility model relates to a kind of angle-bender, relates in particular to a kind of cold bend(ing) machine that is applicable to large intensity steel.
Background technology
High strength cast iron refers to that intensity rank is more than 400MPa, meet the reinforcing bar of the HRB400 that specifies in GB GB1499.2-20007, HRB500 level requirement of strength and external screw-thread steel standard respective strengths rank (as English mark 460B, B500B etc.), it has, and intensity is high, high comprehensive performance, few with material, reduce the advantages such as resource consumption.
National policy clearly represents, accelerates to eliminate 335MPa and following reinforcing bar, promotes intensity 400MPa and above reinforcing bar.In the end of the year 2013, in architectural engineering, eliminate 335 MPa grade reinforcing steels; In the end of the year 2015, high tensile reinforcement output accounts for 80% of spiral total output, and in architectural engineering, use amount reaches the more than 65% of building bar total amount; To large-scale tall buildings and large span public building, preferentially adopt 500 MPa grade reinforcing steels, improve year by year production and the application percentage of 500 MPa grade reinforcing steels; Carry out the application technology research and development of 600 MPa grade reinforcing steels; For earthquake prone areas, emphasis application high yield ratio, the high-strength quake-proof reinforcing steel bar that uniform elongation is high.
In order to respond national policy, also, for the long term growth of enterprise, the production technology of high strength cast iron has had larger development, has formed perfect product standard system, and ripe production Technology system.
Owing to producing high strength cast iron, there are some problems in the cold-bending property that detects high strength cast iron.
By clod wash reinforcing bar, can observe clod wash and can or can not occur crackle later; Can find whether rebar surface exists some tiny micro-cracks, and these crackles can expand after clod wash, are very easy to find; Some concealed wires that can observe surface can or can not extend and intensification etc. after bending, thereby better improve the quality of reinforcing bar.As shown in Figure 1, old forming mill, cannot accurately control the crooked radian of reinforcing bar, and in the time of bending high strength cast iron, often because of pressure Frequent Troubles not, cannot detect timely performance after high strength cast iron clod wash, gives to produce band and serve trouble.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model is to propose a kind of angle-bender.
The purpose of this utility model, to be achieved by the following technical programs: a kind of angle-bender, it is characterized in that: described angle-bender is by flexual center bistrique, the hydraulic cylinder composition that cylinder mechanism and position are fixing, described flexual center bistrique is detachably secured to hydraulic cylinder push rod, a flexual center bistrique dorsad side of push rod is made as semicircle cambered surface, and flexual center bistrique has corresponding bar gauge to be bent and the set of the optional cambered surface diameter of material, described cylinder mechanism comprises cylinder backing plate and two cylinders with plural jack, described two the relative hydraulic cylinder push rod of cylinder axis are that mirror image is symmetrical to be plugged in jack, described flexual center bistrique is driven in hydraulic cylinder and advances and retreat and compress reinforcing bar between two cylinders.
Further, described cylinder mechanism is provided with fixed block, and fixed block is set up in two cylinder tops and fixes two cylinders.
Further, described hydraulic cylinder is provided with fixing fixture block.
Further, it is adjustable that the cambered surface diameter of the corresponding flexual center bistrique of described two cylinders is plugged in jack position.
Applying angle-bender of the present utility model has advantages of: crooking ability is stronger, easily the higher reinforcing bar of bending strength; Bending radius can change, and the equal capable of regulating of each parts is changed, applied widely, is applicable to the bending of all size reinforcing bar; Simple to operate, security performance is better, and the probability that when bending, reinforcing bar ejects is very little.
Brief description of the drawings
Fig. 1 is angle-bender structural representation of the prior art.
Fig. 2 is a kind of angle-bender structural representation of the utility model.
Detailed description of the invention
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, so that technical solutions of the utility model are easier to understand, grasp.
As shown in Figure 2, a kind of angle-bender, especially, angle-bender is by flexual center bistrique 1, the fixing hydraulic cylinder 3 in cylinder mechanism 2 and position forms, flexual center bistrique 1 is detachably secured to hydraulic cylinder 3 push rods 31, a flexual center bistrique 1 dorsad side of push rod 31 is made as semicircle cambered surface, and flexual center bistrique 1 has corresponding bar gauge to be bent and the set of the optional cambered surface diameter of material, cylinder mechanism 2 comprises cylinder backing plate 4 and two cylinders 5 with plural jack 41, two relative hydraulic cylinder 3 push rod 31 axis of cylinder 5 are that mirror image is symmetrical to be plugged in jack 41, flexual center bistrique 1 is driven in hydraulic cylinder 3 and advances and retreat and compress reinforcing bar 7 between two cylinders 5.
Wherein, cylinder mechanism 2 is provided with fixed block 21, fixed block 21 is set up in two cylinder 5 tops and fixes two cylinders 5, fixed block 21 can be controlled reinforcing bar 7 tracks simultaneously, prevent that reinforcing bar 7 from phenomenon occurring to eject in BENDING PROCESS, hydraulic cylinder 3 is provided with fixing fixture block 6, prevents that the excessive hydraulic cylinder that causes of the elasticity of flexure is subjected to displacement.
In addition, it is adjustable that the cambered surface diameter of two corresponding flexual center bistriques 1 of cylinder 5 is plugged in jack 41 position, can adjust cylinder 5 positions according to the reinforcing bar of different model.
The specification limit of the utility model clod wash unit as detailed below.
Hydraulic cylinder part, selects the suitable hydraulic cylinder of stroke, the preferably hydraulic cylinder of 50~440mm stroke, and model is: CD250B125/90-400A10/02CADMA.By connecting fluid pressing system, hydraulic cylinder push rod can be realized controllable release and retraction, as the power resources of bending high strength cast iron, selects the hydraulic system of the bending 500MPa rank of energy, to ensure enough crooked pressures.
