The invention discloses a kind of reinforcing bar Rapid connecting clamp head, it includes joint housing, fixture block, compresses flexible member and gland, fixture block is combined loaded on inside joint housing by several pieces, its outer surface is engaged to form inclined-plane with the inner surface of joint housing, the angle of friction that the surface is more than fixture block inner surface with axis angle and reinforcing bar outer surface is formed.The rotary gland acts on the axial force of fixture block one by compressing flexible member.Spacer ring is provided between described fixture block and compression flexible member；Described fixture block inner surface is machined with the hangnail in opposite direction with steel bar motion.In use, in the head insertion reinforcing bar Rapid connecting clamp head of broken string, rebar surface is acted on by radial component caused by inclined-plane, the frictional force thus brought will drive steel bar motion.The device is ease in use, quick and convenient relative to conventional method.
Description
Technical field
The invention belongs to a kind of servicing unit device of steel bar meter, more particularly to one kind to be used to add in reinforcing bar coiled wires
The reinforcing bar Rapid connecting clamp head of work.
Background technology
Reinforcing bar coiled wires are in cold-drawn, cold rolling and drawing process, due in welding point welding quality, production process
The factors such as tension force break, and particularly wire quality is bad bull situation occurs in a roll, cause continuous line point
From at this moment need the reinforcing bar at broken string to be pulled at disengagement butt welding and connect, being led to by the external rotational force of drawing cylinder in the past
Cross dragging rope to realize, but due to rebar surface relative smooth, it is larger with bar connecting difficulty to pull rope, waste time and energy and effect not
It is good, also pulled sometimes by manpower, add labor intensity.
The content of the invention
Problem to be solved by this invention is to provide a kind of reinforcing bar Rapid connecting clamp head, and it can need to pull reinforcing bar in broken string
When, will easily rope and bar connecting be pulled, improve and pull reinforcing bar efficiency.
Reinforcing bar Rapid connecting clamp head of the present invention, it includes joint housing, fixture block, compresses flexible member and gland, fixture block by
Several pieces combine loaded on inside joint housing, and its outer surface is engaged to form inclined-plane with the inner surface of joint housing, with it
The internal diameter of the change fixture block of relative position change, matching surface and the axis angle of fixture block and joint housing are more than fixture block
The angle of friction that inner surface is formed with reinforcing bar outer surface.The rear portion of joint housing is provided with spiral cover, and rotary gland passes through pressure
Tight flexible member acts on the axial force of fixture block one, because outer surface is engaged with the inner surface of joint housing, makes fixture block initial shape
State is in the front end of joint housing, and now fixture block endoporus is minimum.
In order to avoid fixture block during work and the influence between flexible member is compressed, is provided with spacer ring therebetween；In order to
Increase mutual coefficient of friction and the hangnail in opposite direction with steel bar motion is machined with fixture block inner surface；Compress flexible member
Cylindroid helical-coil compression spring can be used.
For the ease of the connection with pulling rope, draw ring is provided with gland.
It is connected, is put to broken string with the draw ring on gland in use, pulling rope.The head insertion reinforcing bar of broken string is fast
In fast connecting clip, the head of multi-clove type fixture block can be subjected to chamfering for the ease of smoothly insertion, be pressed from both sides during inserting reinforcing bar
The resistance that block is overcome compression flexible member by axial force is moved rearwards, now, fixture block outer surface and joint housing inner surface
Coordinate, fixture block endoporus becomes greatly, now elastic by compressing until gland is arrived on top in reinforcing bar insertion fixture block when more than bar diameter
The inclined-plane that the inner surface of the effect of element axial force, fixture block outer surface and joint housing is formed can produce radial component, make fixture block
Inner surface acts on the normal pressure of rebar surface one, and frictional force can prevent reinforcing bar from outwards extracting out caused by this normal pressure.Restricted when pulling
When pulling reinforcing bar by draw ring, connecting clip, joint housing acts on the axial force of multi-clove type fixture block one (running resistance), by oblique
Face can produce radial component, and this radial component forms force action in bar list with normal pressure caused by above-mentioned compression flexible member
Face, the frictional force thus brought will drive steel bar motion, because matching surface and axis angle are more than fixture block inner surface and reinforcing bar
The angle of friction that outer surface is formed, cause reinforcing bar the more to drag the more tight without releasing during pulling, after pulling in place, gland is twisted
Pine, after the pressure release for compressing flexible member, the power acted on reinforcing bar disappears, so that it may extracts reinforcing bar out.It is ease in use, quick
It is convenient.
Brief description of the drawings
Fig. 1 is one of structural representation (reinforcing bar penetrate before state) of reinforcing bar Rapid connecting clamp head.
Fig. 2 is two (reinforcing bars penetrate after state) of the structural representation of reinforcing bar Rapid connecting clamp head.
Wherein, 1, draw ring, 2, gland, 3, compress flexible member, 4, joint housing, 5, spacer ring, 6, fixture block, 7, reinforcing bar.
Embodiment
Reinforcing bar Rapid connecting clamp head of the present invention is can be seen that from Fig. 1 and Fig. 2, it includes joint housing 4, fixture block 6, compressed
Flexible member 3 and gland 2, loaded on inside joint housing 4, its outer surface is engaged fixture block 6 with the inner surface of joint housing 4, with
The internal diameter for the change fixture block 6 of their relative positions changes, and compresses flexible member 3 and acts on the axle of fixture block 6 one by gland 2
Xiang Li, the endoporus of the original state of fixture block 6 is set to be in minimum.
Fixture block 6 and the matching surface of joint housing 4 are more than the inner surface of fixture block 6 and the outer surface institute shape of reinforcing bar 7 with axis angle
Into angle of friction.The inner surface of fixture block 6 has the hangnail opposite with the direction of motion of reinforcing bar 7, to increase mutual coefficient of friction.
Compress and be provided with spacer ring 5 between flexible member 3 and fixture block 6, compression flexible member 3 is cylindroid helical-coil compression spring.
Draw ring 1 is provided with gland 2.
