The purpose of this utility model is achieved through the following technical solutions:
A kind of bender lazy-tongs, it comprises slide block, slip cap and swing arm, described slide block moves up and down under the drive of oil cylinder, one side of described slide block is installed with slip cap, the side of described slip cap is provided with two neighbouring rectangular recess, i.e. the first groove and the second groove, the upper wedge of the described embedded right-angled trapezium shape of the first groove and the lower wedge of right-angled trapezium shape, on this, wedge and lower wedge are combined and are formed a cuboid, the hypotenuse of described upper wedge and lower wedge cooperatively interacts, and the angle α of the hypotenuse of lower wedge and horizontal direction is acute angle, the movable block of the described embedded rectangle of the second groove, the upper surface of described movable block contacts with the lower surface of described lower wedge, movable block can move left and right in this second groove, on described movable block, be provided with synchronizing shaft, the left end of described swing arm is set on this synchronizing shaft, the right-hand member of described swing arm is set on fixed axis, the right-hand member of described swing arm can rotate around this fixed axis,
It also comprises adjustment bolt, and the sidespin that described adjustment bolt does not arrange slip cap from slide block enters slide block and passes, and props up the sidewall of wedge.
Preferably, described adjustment bolt is plain bolt or hinged bolts.
Preferably, the inclined-plane sharp angle α of described lower wedge is 30 °～60 °.
3, beneficial effect
Than prior art, the utility model has the advantage of:
(1) the utility model comprises the upper wedge of swing arm, movable block, right-angled trapezium shape, the lower wedge of right-angled trapezium shape, slide block and adjustment bolt, and slide block moves up and down under the active force of oil cylinder power, drives swing arm to rotate around synchronizing shaft.Owing to adjusting one end of bolt, prop up upper wedge, so can adjust by adjusting the degree of tightness of bolt, upper wedge is applied to the thrust of a level, again due to the inclined-plane contact between upper and lower wedge, now, upper wedge can have a downward pressure to lower wedge, thereby makes under right-angled trapezium shape the gap between wedge and movable block moderate.After operation a period of time, can regulate the length of adjusting bolt according to actual conditions, and then control the pressure size of upper wedge to lower wedge.The utility model can be adjusted the fit clearance of slide block slip cap and wearing and tearing generation of swing arm in upper and lower running effectively, has reduced bender operating cost;
(2) the utility model is simple in structure, reasonable in design, is easy to manufacture.
