Technical field

The utility model relates to reinforcing bar machining tool, relates in particular to a kind of large-diameter and high-strength reinforcing bar crooked dish made in Great Britain.

Background technology

Existing bending machine (bending machine is numerical-control bending machine, accurate crooked needed angle, adjustable speed) can only curved ф 50mm reinforcing bar according to GB bar bending radius (5d) maximum, if just cannot meet according to the curved ф 50mm of American Standard bending radius (10d).

Summary of the invention

The purpose of this utility model is, a kind of bending dish that can accurately process large-diameter and high-strength bar bending made in Great Britain is provided.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of large-diameter and high-strength reinforcing bar crooked dish made in Great Britain comprises driving-disc, deep bid, shallow bid, the stopping means that is driven rotation by drive unit;

Described shallow bid is superimposed upon deep bid top, and the center of circle of deep bid is coaxial with the center of circle of shallow bid, and fixed axis through shallow bid, deep bid, driving-disc, is fixed as one shallow bid, deep bid, driving-disc successively, and driving-disc rotarily drives deep bid, shallow bid rotates together;

Described deep bid edge is provided with the limit axle that exceeds large panel surface, between limit axle inner edge and little plate edge, has interval;

Reinforcing bar is put into interval, and stopping means carries out spacingly to putting into the reinforcing bar at interval, makes reinforcing bar pass through stopping means along fixed-direction.

Further, stopping means preferred version, stopping means comprises movable axle and at the fixing runner of described movable axle front end, mobile movable axle contacts runner and holds out against the reinforcing bar of putting into interval, deep bid, shallow bid rotarily drive interval rotation, put into the reinforcing bar at interval and follow interval to rotate, the reinforcing bar contacting with runner, the tangent line of edge contact moves.

Further, the preferred version of limit axle, establishes bossed rib on the axle inner edge of limit.

All right, a kind of large-diameter and high-strength reinforcing bar crooked dish made in Great Britain also comprises overturn cover, and described overturn cover one end is fixed on shallow bid, and the other end can be movably fixed to limit axle.

A kind of large-diameter and high-strength reinforcing bar crooked dish made in Great Britain that the utility model provides, it is fixing that reinforcing bar is put into interval, stopping means makes to put into interval reinforcing bar and passes through stopping means along fixed-direction, start drive unit and drive driving-disc rotation, driving-disc rotarily drives deep bid, little disc spins, the reinforcing bar being simultaneously fixed in interval is followed deep bid, shallow bid rotates together, steel disk is in rotary course, spacing because of the fixing and stopping means at interval, reinforcing bar and shallow bid close contact, in rotary course, complete and bend, the size of shallow bid diameter has determined to bend the size of radius, in the process bending, needing only reinforcing bar contacts closely and can complete refining bending with shallow bid, for processing major diameter, when high strength cast iron is crooked, the diameter of shallow bid is corresponding increase also, shallow bid edge radian is larger, be more conducive to reinforcing bar and shallow bid close contact.

On the axle inner edge of limit, establish bossed rib, rib makes to put into fixing better of the steel disk at interval.

Overturn cover one end is fixed on shallow bid, and the other end can be movably fixed to limit axle, opens the movable stiff end of overturn cover, reinforcing bar is put into behind interval, more movable stiff end is fixed, and in the time of can guaranteeing to rotate, the reinforcing bar of putting into interval can not throw away.

In figure, driving-disc 1, deep bid 2, shallow bid 3, stopping means 4, fixed axis 5, limit axle 6, interval 7, workbench 8, movable axle 41, runner 42.

The specific embodiment

The first embodiment, in Fig. 1, a kind of large-diameter and high-strength reinforcing bar crooked dish made in Great Britain comprises driving-disc 1, deep bid 2, shallow bid 3, the stopping means 4 that is driven rotation by drive unit, the diameter of shallow bid 3 is 9 times of ф 50mm bar diameter, and driving-disc 1, deep bid 2, shallow bid 3, stopping means 4 are positioned on workbench 8;

Described shallow bid 3 is superimposed upon deep bid 2 tops, the center of circle of deep bid 3 is coaxial with the center of circle of shallow bid 2, fixed axis 5 through shallow bid 3, deep bid 2, driving-disc 1, is fixed as one shallow bid 3, deep bid 2, driving-disc 1 successively, and driving-disc 1 rotarily drives deep bid 2, shallow bid 3 and rotates together;

Described deep bid 2 edges are provided with the limit axle 6 that exceeds deep bid 2 surfaces, between limit axle 6 inner edges and shallow bid 3 edges, have interval 7, and interval 7 is ф 50mm reinforcing bar fixedly, on limit axle 6 inner edges, establishes bossed rib;

Described stopping means 4 comprises movable axle 41 and at the fixing runner 42 of described movable axle 41 front ends, mobile movable axle 41 makes runner 42 contact and hold out against the reinforcing bar of putting into interval 7, deep bid 2, shallow bid 3 rotarily drive interval 7 rotations, putting into the reinforcing bar at interval 7 follows interval 7 to rotate, the reinforcing bar contacting with runner 42, the tangent line of edge contact moves.
