Abstract
The utility model relates to a bending hoop shaft retractor device in a reinforcing steel bar hoop bending machine. Two kinds of traditional reinforcing steel bar hoop bending machines generally exist, one kind of traditional reinforcing steel bar hoop bending machines is of a program control type, is high in automation degree, but is more sensitive to rust and dust which drop off from the surface of a reinforcing steel bar, and is high in failure rate and maintenance difficulty and maintenance cost; and the other kind of traditional reinforcing steel bar hoop bending machines is of a mechanical type, and is larger in size and serious in noise pollution. The torque is transmitted by a transmission shaft, so that a cam on the transmission shaft rotates around the transmission shaft, when the outline curve on the cam presses a driven rod to do an intermittent reciprocating movement, a rope is drawn, and a drawing force in the movement direction of the driven rod is changed into retraction and traction in the axial direction of a hoop bending shaft through two reversing wheels. When the cam rotates to leave a contact region and the hoop bending shaft restores to an original position under the action of a spring force, therefore the flexible action of the hoop bending shaft is realized. The bending hoop shaft retractor device has the remarkable advantages of reasonable design, compact structure, small size, low cost, flexible and reliable action and small working noise.
Description
Technical field
The utility model relates to the telescopic drive structure of bending hoop axle in the bending hoop shaft extension compression apparatus, particularly a kind of stirrup bender in a kind of stirrup bender, belongs to Machine Design manufacturing technology field.
Background technology
Development along with science and technology, the stirrup that uses in the architectural engineering no longer completes by simple Aided Machine by manual, the beginning of various bending hoop machinery is used on the construction site widely, and is bringing into play artificial irreplaceable advanced effect.Make a general survey of all kinds of bending hoops machineries that occur at present, roughly be divided into pure mechanical type with two kinds of program control type.Though the automaticity of program control type is high, but disposable input cost is relatively large, environment for use requires also relatively high, this program control machinery requires to be arranged on indoor usually, and comparatively responsive to the rusty stain dust that rebar surface comes off, thereby fault rate is high, maintenance difficulty and maintenance cost are larger, therefore, use in the engineering at present comparatively general still take pure mechanical type as main.Usually the shaping of stirrup is made by the bending of bull order, in a kind of stirrup bender of pure mechanical type, the certain phase angle of bending connecting lever rotation when the first order, reinforcing bar is gone for a stroll after hoop axle rotation finishes first bending, the bending hoop axle certain distance of must fastly shrinking back vertically, abdicate the motion space that reinforcing bar enters the second order bending, otherwise postorder bending action can't realize.This stirrup bender is at the rear end of bending hoop axle connection for transmission rope, and the other end of rope connects lever, and lever is realized swinging by the rotation compressing of power spindle, and rope for traction is realized towing bending hoop axle retrude thus.Such type of belt drive is determined by the operation principle of its design, the space of internal body must be enough large, namely must design enough spaces to guarantee that lever motion is not interfered, therefore the volume of frame is larger, and since the answer of lever be subjected to spring controlled, therefore strike note is larger, and noise pollution is serious.
Summary of the invention
The technical problem that stirrup bender bending hoop shaft extension contracting mechanism volume is large, noise is high for present mechanical type the utility model proposes the bending hoop shaft extension compression apparatus in a kind of stirrup bender.
To achieve these goals, the utility model Bian gets following technical scheme and implements: the bending hoop shaft extension compression apparatus in a kind of stirrup bender, comprise frame, casing, connecting lever, axle sleeve, bending hoop axle, spring, bearing, reverse wheel, rope, follower lever, cam, power transmission shaft, casing is fixed on the frame, the bottom of casing is provided with guide-track groove, axle sleeve is connected to box house by bearing, and the bending hoop shaft clearance is engaged in the hole of axle sleeve, and it axially and between the casing is provided with spring; Be provided with rope between the rear end of described bending hoop axle and the follower lever, the rope middle part is supported by two reverse wheels, and follower lever is provided with the guide rail key, it is characterized in that: be provided with cam between described power transmission shaft and the follower lever, described cam is nested with and is fixed on the power transmission shaft; The back side of described follower lever is provided with the guide rail key, and guide-track groove is arranged on the bottom of described casing, and follower lever slides in guide-track groove with the guide rail key.
The utility model makes the setting contour surface drive follower lever on the cam make the set a distance rectilinear motion by the power transmission shaft transmitting torque, and pulling cable traction bending hoop axle retrude; After the contact zone was left in the cam rotation, contour surface was returned to the home position under the effect of spring force, and namely the bending hoop axle advances to the origin-location.Thereby realize the expanding-contracting action of bending hoop axle.
The remarkable advantage that the utlity model has reasonable in design, compact conformation, volume is little, cost is low, be active in one's movements reliable, operating noise is little.
Description of drawings
Accompanying drawing 1 is main TV structure schematic diagram of the present utility model;
In accompanying drawing 1,2: 1 casing, 2 connecting levers, 3 axle sleeves, 4 bending hoop axles, 5 springs, 6 reverse wheels, 7 ropes, 8 follower levers, 9 frames, 10 power transmission shafts, 11 cams.
The specific embodiment
Shown in accompanying drawing 1,2, casing 1 is fixed on the frame 9; Axle sleeve 3 is connected to the inside of casing 1 by bearing; Bending hoop axle 4 matched in clearance are in the hole of axle sleeve 3, and it axially and between the casing 1 is provided with spring 5; One end of rope 7 is connected with the rear end of bending hoop axle 4, the other end and follower lever 8, and the middle part of rope 7 is provided with two reverse wheels 6 and supports; The bottom of frame 1 is provided with the guide-track groove on the vertical direction, and follower lever 8 is provided with the guide rail key, and the guide rail key on the follower lever 8 is slidingly fitted in the guide-track groove on the frame 1; Power transmission shaft 10 is provided with cam 11,
The utility model is under the work normality, bending hoop axle 4 is subjected to the spring power effect of spring 5 to be in all the time extended position, when needs bending hoop axle 4 is deactivated the zone, power transmission shaft 10 band moving cams 11 rotate, make the contour surface compressing follower lever 8 on the cam 11 do intermittently to move back and forth, and drag rope 7, and by two reverse wheels 6 power on follower lever 8 moving directions is changed into the retrude towing that power on bending hoop axle 4 axial directions realizes bending hoop axle 4, in the bending hoop axle 4 indentation axle sleeves 3.Bending hoop axle 4 is returned to the home position under the active force of spring 5 after the contact zone is left in cam 11 rotations, thereby realizes the expanding-contracting action of bending hoop axle.
