Abstract
The utility model discloses the device that a kind of pipe fitting is bent, including the front nip rollers arranged along pipe fitting axis direction and rear niproll, induction coil is placed in pipe fitting and treats crook, and the upper concave roller of two identical sizes is arranged above bend pipe, a plurality of deflector rolls are uniformly arranged between two recessed rollers, recessed roller is provided with below bend pipe, this apparatus structure is simple, eliminates the clamping time, can continuous bending, processing efficiency is substantially increased, cost is reduced, and the circular arc degree of pipe fitting can be controlled well.
Description
Technical field
The utility model is related to the device that a kind of pipe fitting is bent, and belongs to machining technology field.
Background technology
Bend pipe be the energy, chemical industry industrial circle in one of the most important structural member of pipeline, it is generally curved using fire bending
Machine is processed, and fire bending bender schematic diagram is as shown in figure 1, production technology is by bend pipe push machine to be curved in steel pipe after straight tube blanking
Part puts induction coil, and tube head is blocked with mechanical rocker arm, electric current of intermediate frequency heating steel pipe is passed through in induction coil, when temperature of steel pipe liter
When height arrives mecystasis, promoted, bent with mechanical thrust in steel pipe rear end.Shortcoming：Need repeated clamping, processing efficiency ratio
It is relatively low, and each position of circular arc curvature precision it cannot be guaranteed that.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides the device that a kind of pipe fitting is bent, and eliminates
The clamping time, can continuous bending, substantially increase processing efficiency, reduce cost, and the circular arc degree of pipe fitting can be controlled well.
The utility model solves the technical scheme that its technical problem used：
The device that a kind of pipe fitting is bent, it is characterised in that：The device includes the front nip rollers arranged along pipe fitting axis direction
With rear niproll, treat that crook sets induction coil in pipe fitting, two identical chis of arrangement above the whole story two positions of position are bent in bend pipe
Very little upper concave roller, uniformly arranges a plurality of deflector rolls between two upper concave rollers, and recessed roller is provided with below bend pipe.
Further, the upper concave roller and recessed roller are close to bend pipe outer wall, are arranged along camber line, to ensure the circular arc degree of pipe fitting,
Prevent pipe fitting from occurring warpage.
The beneficial effects of the utility model are：
This apparatus structure is simple, eliminates the clamping time, can continuous bending, substantially increase processing efficiency, reduce cost,
And the circular arc degree of pipe fitting can be controlled well.
