Abstract

The utility model relates to an adjustable type rebar bending machine. A traditional bending machine takes up a great deal of time to change a bending mechanism when bending various standards of rebar hoop. Through a mechanism which enables gear teeth of a gear shaft which is on a box body to mesh with racks which are on the machine frame, the adjustable type rebar bending machine enables a T-shaped key which is on a base level of the box body to slide along a T-shaped groove of the base level of the machine frame driven by the gears and racks through a manual rotating gear shaft so at to achieve displacement and adjustment of the bending mechanism of the box body. When the graduation is arranged on the outer side face of one track, rapid and precise adjustment and placement can be achieved according to prearrangement, and the box body can be fixed on the machine frame through a compression screw. The adjustable type rebar bending machine has the advantages of being reasonable and compact in structure and adjusting the place conveniently and rapidly.

Description

A kind of adjustable reinforcing bar hoop bender

Technical field

The utility model relates to a kind of stirrup bender, is specifically related to the adjusting device of bending mechanism position on frame, 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.In a kind of stirrup bender of pure mechanical type, some groups of bending mechanisms are arranged in a linear, every group of bending mechanism swings and drives the certain phase angle of pulled by cable connecting lever rotation by the power transmission shaft activation lever, finish a bending action in the stirrup, swung and driven again pulled by cable bending hoop axle after a bending action is finished shrinks back vertically by the power transmission shaft activation lever, abdicate the space that reinforcing bar continues bending, make reinforcing bar can enter without barrier follow-up bending operation program.When the stirrup of bending different size, need the relative position between some groups of bending mechanisms of conversion, because the bending mechanism position of this machinery and the length of rope have relevance, and shrinking back all by pulled by cable of connecting lever rotation and bending hoop axle, the size of connecting lever rotating photo parallactic angle is determined by the length of rope again, therefore during conversion bending mechanism position, must untie two fly ropes in every group of bending mechanism, also rope and driving member will be connected and can work on after the adjustment.This adjustment process very complex, take a lot of work, time-consuming.Basic reason is: many ropes of working simultaneously, when the end positions of rope connection changes, can't find the accurate distance of every rope point-to-point transmission accurately quickly.If adjust badly, also directly affect the size at stirrup bending angle, cause the shape of stirrup to make a variation.Therefore people wish to have a kind of more convenient, position regulator efficiently, apply in the stirrup bender.

Summary of the invention

Adjust the extremely inconvenient defective in position of bending mechanism for the stirrup bender of present mechanical type because of the variation of stirrup specification, the utility model provides a kind of adjustable reinforcing bar hoop bender, and it has realized that the position adjustment of bending mechanism is quick, accurately.

To achieve these goals, the utility model Bian gets following technical scheme enforcement: comprise frame, casing.Gear shaft, bearing, sector gear, cam, strong, clamping screw are arranged in the casing, and power transmission shaft, tooth bar are arranged on the frame.Casing is T shape case structure, and its lower plane is the datum level that two parallel orbits consist of; Frame is frame-shaped construction, and plane is the datum level that two parallel orbits consist of on it, and with the coupling of described casing datum level.Sector gear, cam are nested with on power transmission shaft, and the keyway engagement that is provided with by the key that is provided with in sector gear, the cam endoporus and power transmission shaft.A medial surface in two parallel orbits of described frame datum level is provided with tooth bar, is meshed with the gear teeth on the sprocket drive spindle in the casing.Described gear shaft is vertically connected on the casing by bearing.Be provided with along its length T-slot on the datum level of described frame, be provided with along its length T shape key on the described casing datum level, the coupling of described T shape key is in described T-slot.

The utility model is by the structure that is meshed with tooth bar on the frame of the gear teeth on the gear shaft on the casing, and make T shape key on the casing datum level under the driving of gear, tooth bar by the manual rotation gear shaft, slide along the T-slot on the frame datum level, thus the Adjustment of displacement of bending mechanism in the realization casing.If the lateral surface at a rail arranges scale, then can quick and precisely regulate according to prior setting and put in place, and can casing be fixed on the frame by clamping screw.

The utlity model has compactness rational in infrastructure, position efficiently advantage easy to adjust.

The specific embodiment

Shown in accompanying

drawing

1,2,3, frame 1 is closed-in construction, and plane is a on it; Casing 2 is T shape case structure, and its lower plane is a '; Casing 2 is connected on the frame 1 by clamping screw 6; Sector gear 8 and cam 9 are slidingly connected at the outside of power transmission shaft 7 by key 10 and keyway 701; The a of frame 1 is provided with along the T-slot 101 on the frame length direction, and a ' of casing 2 is provided with T shape key 201, and T shape key 201 couplings on the casing 2 are in the T-slot 101 of frame 1; A adjacent side on the frame 1 is provided with along the tooth bar 4 on frame 1 length direction, and gear shaft 3 is vertically connected on the inside of casing 2 by bearing 5, and the gear on the gear shaft 3 is meshed with tooth bar 4 on the frame 1; Keyway 701 length on the power transmission shaft 7 are greater than the thickness of casing 2.

When needs are adjusted the bending mechanism position, unclamp the clamping screw 6 on the casing 2, by means of spanner rotary teeth wheel shaft 3, casing 2 is under the engagement of the tooth bar 4 on gear shaft 3 and the frame 1 drives, slide along T shape key and T-slot direction, meanwhile sector gear 8 and cam 9 along the endwisely slipping of power transmission shaft 7, are realized the position adjustment of whole bending mechanism under the circumferential constraint of key 10, after adjusting to the right place, fastening clamping screw 6 is spacing.
