Abstract

The utility model relates to a steel bar bending machine, which comprises a torque plate and a supporting base that are driven by the motor and is positioned on the workbench, wherein the cylinder eccentrically arranged on the torque plate is an adjustable structure in the axial direction; the baffle in the supporting base is connected with at least two bolt tops ends that control the advancing and retreating of the baffle. The utility model changes the fixed rolling column hole on the torque plate into a movable rolling column structure that is continuously adjustable along the axial groove position as well as a movable structure with continuously adjustable baffle position. Thereby the steel bar of any diameter can be positioned at the correct chucking position through the bolt adjustment. The bending effect can meet the design requirement and the construction quality can be ensured.

Description

A kind of angle-bender

Technical field:

The utility model relates to the machinery that bullion is carried out bending.

Background technology:

In construction, often need carry out bending before the concrete cast to reinforcing bar.Existing angle-bender, as commercially available GW6-40L type, have porous on its torsion plate, cylinder can be inserted in every hole, be arranged on the other reinforcing bar rivet holder of torsion plate and also have porous, every hole also can be inserted and be decided roller, when bending not when the reinforcing bar in collinear footpath or crooked different radii, needs respectively cylinder and decides the different position, hole of roller insertion.Under the cylinder pressure arc operation effect, reinforcing bar is by the arc bending when the power effect of supporting of deciding roller and torsion plate rotation.Because each Kong Douwei is spaced, also promptly there is level to arrange, reinforcing bar is loosening easily, and crooked precision is difficult for guaranteeing.

Summary of the invention:

The purpose of this utility model provide a kind of can be to the accurately screens of reinforcing bar of different-diameter, the angle-bender that bending effect is good.

The utility model comprises by machine shaft and drives and be arranged on torsion plate, rivet holder on the workbench, it is characterized in that the cylinder that off-centre is installed on the torsion plate is the radial position adjustable structure, the plate washer in the rivet holder is connected with the bolt top of two its advance and retreat of control at least.The radial position adjustable structure is that torsion plate has radially groove, and groove is run through in cylindrical spiral shell axle lower end, and spiral shell is locking positioning not.Stove bolt runs through spiral shell seat and the threaded engagement that is fixed on the workbench.The baffle plate front panel roller that can be connected.

The utility model changes the fixedly roller hole on the torsion plate into the radially continuously adjustable roller removable frame in groove position, and the rivet holder baffle plate is along the continuously adjustable removable frame in rectilinear direction position, make the reinforcing bar of arbitrary diameter can both obtain accurate screens by the bolt adjusting, bending effect can be realized designing requirement, and construction quality is guaranteed.

Description of drawings:

Fig. 1 is the utility model-example structure vertical view.

Fig. 2 is Fig. 2 right view.

Fig. 3 is the rearview of torsion plate among Fig. 2.

The specific embodiment:

With reference to Fig. 1, Fig. 2, Fig. 3, rivet holder and torsion plate 2 are installed on the working plate 1, two parallel bolts 12 that rivet holder is connected by baffle plate 10, with plate washer 10 rear sides, weld to be connected on the work top and and constitute by the spiral shell seat 11 that bolt 12 runs through.Torsion plate 2 is driven by machine shaft, and rotating shaft 4 sides through slowing down have radially oval groove 2.1, and cylinder 6 is set on this groove, and this cylinder is shaped on axle center bolt 5, and bolt 5 lower ends are run through in the groove 2.1 of torsion plate 2, and available spiral shell does not lock.Web position along groove 2.1 extend radially lines is shaped on little spiral shell seat 2.2, and minor adjustment bolt 7 connects with cylinder 6 spiral shells after running through this little spiral shell seat, rotates minor adjustment bolt 7 cylinder 6 is moved along groove 2.1.Rotating shaft 4 can be overlapped the sleeve 3 of different-diameter, to adapt to the needs of the differently curved radius of reinforcing bar.In order to reduce the rough surface reinforcing bar to the frictional force that baffle plate 10 produces, reduce motor power consumption, several roller bearings 9 that are connected in baffle plate 10 fronts make the sliding friction between reinforcing bar and the baffle plate change rolling friction into.

The course of work: at first according to reinforcing bar by bend diameter, in rotating shaft 4, change the sleeve 3 of respective diameters, to be inserted on the torsion plate between the cylinder 6 and sleeve 3 along baffle plate roller 9 by bar bending 8 then, turn adjusting bolt 7 and make cylinder 6 hold out against reinforcing bar 8, then bolt 5 is locked with stationary cylinder 6.Parallelly again turn two baffle plate bolts 12, until plate washer roller 9 with till reinforcing bar 8 touches mutually.Start power supply, torsion plate 2 rotates, and reinforcing bar 8 supports under the power effect at baffle plate roller 9, and its front end is bent with the circular motion of cylinder 6.The broken circle cylinder is represented the turned position after reinforcing bar is bent among the figure.

Reducing gear of the present utility model drives with spur gear, and 400 millimeters gear wheel strengthened output torque during slow shelves were used, and made institute's gas-distributing motor power can be reduced to the 3KW type, and power consumption reduces.In control circuit, by in 45 °, 90 °, 135 ° shift switches of three kinds of angle of bend commonly used, design has the stroke adjustment slide plate, is shaped on this slide plate that normal travel contact, operate miss always stop the contact, return stops the contact, in the operation more accurately, reliable, safety.
