Abstract
The utility model relates to a hydraulic clamp for welding steel bars through air pressure. The utility model solves the problem that steel bars are not overlapped on a straight line during overlapping weld of steel bar weld in building construction. The utility model uses a fixed clamping claw and a movable clamping claw which can both move relatively under the hydraulic pressure of an oil cylinder. The utility model can be widely used for the butt joint and the weld of steel bars in industries such as building industry, etc.
Description
The utility model relates to a kind of hydraulically operated fixture that steel bar gas connects that is used for.
Modern architecture be unable to do without reinforcing bar, in the construction arc welding is often adopted in the welding of bar reinforcement in the past, and it is to adopt the overlap joint welding, makes reinforcing bar not point-blank, has influenced the transmission of stress, easily causes the structural destruction of building, and the expense material of taking a lot of work.
The utility model is intended to use anchor clamps will connect two steel bar ends and a relative fixed, and can in welding process, drive reinforcing bar and do relative motion, make the splice surface produce certain pressure, with the molecule that reaches joint scattering and permeating each other, facilitate metallic molecule crystallization again, improving work efficiency, to reduce cost, and reach higher intensity; It uses hydraulic principle, makes that it is simple in structure, easy to use, volume is little, is applicable to the building trade site operation.
It decides the end that claw (1) is fixedly installed in clamp body (2) the utility model, clamp body (2) middle part has slit vertically, and the slide block that makes movable jaw (5) can drive claw along the rail plate axially-movable in the clamp body (2), the return spring B(3 that can make movable jaw (5) return is housed) in the clamp body (2), the other end of clamp body (2) is equipped with oil cylinder (16), there is the push rod (8) of a band piston (7) its inside, the other end of push rod (8) contacts with the slide block of movable jaw (5), the return spring A(9 that makes piston (7) drive push rod (8) return is housed) in the oil cylinder (16), can in cylinder, provide the high-pressure oil pipe (6) of liquid on the oil cylinder (16) in addition, optional water of liquid or oil.
The claw part that the utility model is decided claw (1) and movable jaw (5) is coupled together an end of deciding pawl (12) and moving pawl (13) by hinge (15), and the other end of deciding pawl (12) and moving pawl (13) has is convenient to the detachable connection mechanism that it links together.
The utility model decides on pawl (12) side relative with moving pawl (13) the fixedly groove of reinforcing bar is arranged, as dovetail groove, serrate slot, netted groove, bar-shaped trough, it can also be to decide to have on the pawl (12) along the axial dovetail groove of clamp body (2), and moving pawl (13) upper edge clamp body (2) axially is equipped with a tooth bar (14).
Tooth bar of the present utility model (14) is a wedge, and it can move along clamp body (2) axial direction on moving pawl (13).
Tooth bar (14) on the moving pawl (13) of deciding claw (1) and movable jaw (5) of the present utility model is to install by the relative direction of microcephaly, so that when movable jaw (5) was mobile, tooth bar (14) can tighten reinforcing bar.
Detachable connection mechanism of the present utility model can be bolted, so that decide claw (1) and movable jaw (5) is held reinforcing bar and tighten up.
Advantage of the present utility model is the utilization activity, deciding claw can be with two reinforcing bars along the straight line relative fixed, and movable jaw drive reinforcing bar is done relative motion, apply certain pressure with the butt joint surface, the molecule that makes joint is scattering and permeating each other, facilitate metallic molecule crystallization again, thereby reach the purpose that improves work efficiency, reduces cost, improves bonding strength; Because it has used hydraulicdriven principle, it is simple in structure, easy to use, volume is little so make, and is applicable to the building trade site operation.
Fig. 1 is a structural representation of the present utility model, and it is as Figure of abstract;
Fig. 2 is the utility model claw structure schematic diagram;
Fig. 3 is moving pawl of the utility model and the structural representation of deciding pawl.
Further specify below in conjunction with accompanying drawing:
By shown in Figure 1, an end of clamp body (2) is installed with decides claw (1), and its other end is equipped with oil cylinder (16), and its middle part is movable jaw (5).It is similar with the claw part-structure of movable jaw (5) to decide claw (1), but deciding claw (1) is fixed as one with clamp body (2), and the slide block (4) in movable jaw (5) and the clamp body (2) is connected, and when axially moving in the guide rail of slide block (4) in clamp body (2), it can drive movable jaw (5) and move vertically by the slit (10) that clamp body (2) middle part is opened vertically.The power of movable jaw (5) motion comes from oil cylinder (16), piston (7) is housed in it, make the return spring A(9 of piston (7) return), piston (7) drives push rod (8) and decides claw (1) to slide block (4) the generation thrust promotion movable jaw (5) of movable jaw (5) is close, makes the return spring B(3 of movable jaw (5) return in clamp body (2) in addition).Can in cylinder, provide liquid in addition on the oil cylinder (16), the high-pressure oil pipe (6) of Ru Shui, oil.The other end of high-pressure oil pipe (6) can connect hydraulic pressure increases device (pump).The claw part of deciding claw (1) and movable jaw (5) by hinge (15) deciding pawl (12) and moving pawl (13) couples together, the other end of deciding pawl (12) and moving pawl (13) has is convenient to the detachable connection mechanism that it links together, as bolt connecting mechanism, also can be shackles mechanism.Deciding has the fixedly groove of reinforcing bar on pawl (12) side relative with moving pawl (13), as dovetail groove etc., can also be equipped with on the moving pawl (13) can be along the wedge tooth bar (14) of clamp body (2) axially-movable, wedge tooth bar (14) microcephaly who decides on the moving pawl (13) of claw (1) and movable jaw (5) is relative, so that at movable jaw (5) to deciding claw (1) when mobile, wedge tooth bar (14) relative motion, thus reach the clamping action of steel bars.
During use, decide claw (1) and clamp a reinforcing bar earlier, make movable jaw (5) clamp another root reinforcing bar again, its joint is contacted relatively, utilize oil hand pump to pass through high-pressure oil pipe (6) when with gas welding heated coupling to the 1300 ℃ left and right sides and add hydraulic oil to cylinder body, pressure can reach 400 kg/cm, and movable jaw under this pressure (5) is done small distance and moved to deciding claw (1), slowly thick joint is ramed the loose soil with a stone-roller after sowing in pressurization, and splice is fused into one.
