Abstract
The utility model discloses a large-diameter high-strength reinforcing steel bar arc bending machine, which comprises a working table, wherein a main working plate is arranged in the middle of the working table; an arc bending plate is arranged on the main working plate; sliding shafts are symmetrically arranged on two sides of the working table; the sliding shafts are provided with arc bending drums and the top ends of the sliding shafts are provided with adjusting lead screws; and the other ends of the adjusting lead screws are provided with adjusting handles. According to the machine, a tooth-shaped arc bending plate is additionally arranged on the main working plate, and the structures of the arc bending drums are additionally arranged on the two sides of the working table, so that a safe and stable arc bending step of a reinforcing steel bar and even a large-diameter and high-strength reinforcing steel bar can be realized under the condition that a threaded reinforcing steel bar ruler is engaged with the tooth-shaped arc bending plate, the production efficiency is increased, and the expenditure that equipment is required to be additionally purchased during large-diameter and high-strength reinforcing steel bar arc bending of enterprises is saved.
Description
Technical field
The utility model relates to a kind of bending machine for reinforcing steel bars, relates in particular to a kind of large-diameter and high-strength bending machine for reinforcing steel bars.
Background technology
Existing bender is mainly plane three cartridge types, mainly utilizes main biography central tube and adjustable supplemental cartridge to carry out the processing of reinforcing bar curved arc.When using bender, generally workpiece to be curved need to be placed between main biography central tube and supplemental cartridge, just begun to make between main biography central tube and workpiece to be curved certain pressure has been arranged, start the machine main biography central tube is rotated, soon to the end the time, with main biography central tube counter-rotating, increase simultaneously the pressure between supplemental cartridge and workpiece when workpiece, like this back and forth crooked back and forth, till being bent to required circular arc or circle always.So not only exist and cause bender unsettled problem in the course of the work because being not easy the location, but also exist in the work engineering because pressure causes more greatly the problem that main biography central tube is easy to wear seriously, fault rate is high, so owing to existing the problems referred to above bender commonly used can't be used for the curved arc of major diameter, high strength cast iron.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of large-diameter and high-strength bending machine for reinforcing steel bars that provides, it not only can solve the bender problem of poor stability in the course of the work, and can solve the problem that main biography central tube is easy to wear seriously, fault rate is high.
The purpose of this utility model is achieved in that
A kind of large-diameter and high-strength bending machine for reinforcing steel bars, it comprises workbench, is provided with main scratch diskette in the middle of workbench, the curved arc dish is installed on main scratch diskette, the workbench bilateral symmetry is provided with slide-bar, and on slide-bar and top is respectively equipped with the curved arc cylinder and regulates screw mandrel, and the other end of regulating screw mandrel is provided with regulating handle.
Described curved arc dish is flute profile curved arc dish, is provided with gear around it.
Described main scratch diskette is arranged in the middle part of workbench.
Described curved arc dish is connected and fixed by high-strength bolt and trundle and main scratch diskette.
Described slide-bar is installed in chute by adjusting screw(rod).
Described curved arc cylinder is connected with central shaft by bearing, and central shaft is connected with slide-bar by jack.
The utility model has been obtained following technique effect:
The utility model has adopted and had additional flute profile curved arc dish on main scratch diskette, and have additional the structure of curved arc cylinder in workbench both sides, it can guarantee reinforcing bar or even major diameter, high-intensity reinforcing bar in the situation that spiral chi and flute profile curved arc dish engagement safety, the stable operation that realizes curved arc, improved production efficiency, having saved enterprise needs the spending of other purchase of equipment to major diameter, high-intensity reinforcing bar curved arc the time.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that Fig. 1 is at the cutaway view at A-A place;
Fig. 3 is that Fig. 1 is at the cutaway view at B-B place.
The specific embodiment
A kind of large-diameter and high-strength bending machine for reinforcing steel bars as Figure 1-3, it comprises workbench 1, be provided with main scratch diskette 2 in the middle of workbench 1, on main scratch diskette 2, curved arc dish 3 is installed, workbench 1 bilateral symmetry is provided with slide-bar 6, on slide-bar 6 and top is respectively equipped with curved arc cylinder 9 and regulates screw mandrel 7, and the other end of regulating screw mandrel 7 is provided with regulating handle 8.Curved arc dish 3 is flute profile curved arc dish, is provided with gear around it.Main scratch diskette 2 is arranged on workbench 1 middle part.Curved arc dish 3 is connected and fixed with main scratch diskette 2 by high-strength bolt 4 and trundle 5.Slide-bar 6 is installed in chute 11 by adjusting screw(rod) 10.Curved arc cylinder 9 is connected with central shaft 13 by bearing 12, and central shaft 13 is connected with slide-bar 6 by jack 14.
When adopting said structure, at first reinforcing bar is placed horizontally between the curved arc dish 3 and both sides curved arc cylinder 9 of workbench 1, make the gear engagement of spiral tooth and flute profile curved arc dish 3, then according to the radian of required curved arc, reach thereby adjust curved arc cylinder 9 by adjusting slide-bar 6 purpose that gives the reinforcing bar certain pressure.Open again bender, in the situation that curved arc is carried out in assurance spiral tooth and 3 engagements of flute profile curved arc dish, guarantee the steady processing of curved arc all the time.
