Description
Technical field
The present invention relates to a kind of straightener, especially a kind of hand-held dish circle wire rod straightener for stub bar.
Background technology
In Investment in fastener industry, large gauge cold forming equipment most employing dish circle wire rod, the horizontal bin of device Host feeding front-end configuration biscuit uncoiling is convenient to material automatic driven unwind, alignment, the horizontal bin of uncoiling is made up of next group pressure wheel upper and many group straightening-wheels, pressure wheel plays uncoiling effect, dish circle wire rod is opened, the strong frictional force that its rotation produces hauls wire rod and send in straightening-wheel, straightening-wheel plays alignment effect, can main frame be sent after raw material piecemeal alignment into, certain spacing (usual 300 ~ 400mm) is had between pressure wheel and straightening-wheel, bin could be sent into after bending dish circle wire rod stub bar need pull straight large during the period distance degree.20mm is less than for material diameter, with sleeve pipe entangle stub bar manually pull directly be easy to realize; Comparatively large for material diameter, between 25 ~ 32mm, a kind of or manually pull straight, but efficiency is low, and labour intensity is large, sometimes needs two people could pull dynamic.
Summary of the invention
The invention provides a kind of hand-held dish circle wire rod straightener for stub bar, its overall volume is little, and structure is simple, lightweight, portable light and flexible, safeguards simple, is applicable to on-the-spot alignment operation, thus reduce the labour intensity of workman, increase work efficiency, reduce production cost.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: hand-held dish circle wire rod straightener for stub bar, comprise frame and gas-liquid booster, gas-liquid booster is made up of pressurizing cylinder, pressurized cylinder, oil storage barrel, the two ends of pressurizing cylinder are respectively arranged with front handlebar and rear handle, and rear handle is provided with button type mechanical valve, it is characterized in that: the pressurizing cylinder in gas-liquid booster is connected with frame bolt, piston rod in pressurizing cylinder is connected with movable head, and two supporting members are fixed in frame; Described supporting member is made up of back shaft and alignment roller, and back shaft is fixed in frame, and alignment roller shell is contained on back shaft, and the supporting surface of alignment roller is provided with locating slot; Described movable head is threaded on the piston rod of pressurizing cylinder, and movable head is provided with locating slot; In alignment process, stub bar two ends are located by supporting member, and movable head pushing stub bar interlude reaches bending alignment object.
To the further restriction of technique scheme, locating slot on described movable head and two supporting members is circular arc Baltimore groove, in alignment process, increase alignment roller outer round surface with by the contact area on alignment round steel surface, make the round steel outer round surface uniform force after alignment, both reach the object of alignment, do not scratched again, flatten its outer round surface.
To the further restriction of technique scheme, described frame is made up of 7075T651 high-strength aluminum alloy material, and its tensile strength is 538MPa, is better than mild steel, and density is 2.73, and weight is equivalent to 1/3 of steel.
To the further improvement of technique scheme, described front handlebar also can be arranged in frame, can increase the stability of this device hand-held like this.
Beneficial effect: in alignment process, stub bar two ends are located by supporting member, movable head pushing stub bar interlude reaches bending alignment object, the present invention has the following advantages: 1. utilize gas-liquid booster to exert oneself greatly, speed is fast, No leakage, festival energy, the advantages such as price is low carry out Design and manufacture, it uses pure air pressure as power source, the when Pascal energy of the big valve piston sectional area of booster is utilized to keep weighing apparatus principle and work, the low pressure of air pressure is improved decades of times supply oil hydraulic cylinder to use, thrust when oil hydraulic cylinder stretches out forces round steel to bend alignment, compared with traditional straightener, more energy-conservation, more environmental protection, more economical, 2. overall volume of the present invention is little, and structure is simple, lightweight, portable light and flexible, safeguards simple, is applicable to on-the-spot alignment operation, cheap.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1 is frame, and 2 is pressurizing cylinders, and 3 is pressurized cylinders, and 4 is oil storage barrels, and 5 is front handlebars, and 6 is rear handles, and 7 is movable heads, and 8 is supporting members, and 9 is stub bars.
Detailed description of the invention
