Abstract
The utility model discloses a manufacturing device for a bent pipe with a small bending radius. A bent pipe mold is arranged, and the bent pipe mold is fixedly connected with a spindle; the spindle is connected with a driving mechanism; the outer cambered surface of the bent pipe mold is provided with a groove for the placement of a pipe; a pipe clamping block is arranged below the bent pipe mold; a pressing roller wheel is arranged below the bent pipe mold; the pressing roller wheel is connected with a pressing roller wheel rack; the surface of the pressing roller wheel is provided with a groove which is matched with a pipe. The utility model has reasonable structure; by the reverse deformation principle that before a steel pipe is bent and deformed, the pressing roller wheel first applies pressure on the steel pipe so that the outer side of the steel pipe is deformed outwards and convexly, in the process of bending, convex deformation can counteract elliptical deformation after bending so that the pipe is also circular in the bending part. Product quality is good.
Description
Technical field:
The utility model relates to a kind of manufacturing installation of bend pipe.
Background technology:
The ratio that bent pipe with small R is meant tube bending radius and caliber is smaller or equal to 1.5 bend pipe.Such bend pipe uses more in the superheater of boiler and reheater, and during existing little R pipe manufacturer, often exists pipe deformation not good, poor quality's problem.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and the small-bend radius bent pipe of formation is out of shape, the manufacturing installation of the measured small-bend radius bent pipe of matter.
Technical solution of the present utility model is:
A kind of manufacturing installation of small-bend radius bent pipe, it is characterized in that: bending die is arranged, bending die is fixedlyed connected with main shaft, main shaft is connected with driving mechanism, the groove of placing pipe is set on the bending die extrados, and the bending die below is provided with the tube grip piece, and the bending die below is provided with pinch rollers, pinch rollers is connected with the pinch rollers frame, and the pinch rollers surface is provided with the groove that cooperates with pipe.
Bending die is monoblock type or split-type.
The utility model is rational in infrastructure, utilize the reversible deformation principle, promptly before the tube bending distortion, pinch rollers is exerted pressure to steel pipe earlier, make the outside of steel pipe produce the distortion of outwards protruding, in BENDING PROCESS, the distortion of protrusion can be offset the ovalizing deflection after bending, make pipe also rounded, good product quality at crooked position.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of an embodiment of the utility model.
The specific embodiment:
A kind of manufacturing installation of small-bend radius bent pipe, bending die 1 is arranged, bending die 1 is fixedlyed connected with main shaft 2, main shaft 2 is connected with driving mechanism 3 (turning handle), and the groove 4 of placing pipe is set on bending die 1 extrados, and bending die 1 below is provided with tube grip piece 5, bending die 1 below is provided with pinch rollers 6, pinch rollers 6 is connected with pinch rollers frame 7, and pinch rollers 6 surfaces are provided with the groove that cooperates with pipe, to hold pipe.Tube grip piece 5 can be by regulating with the adjustable bolt device 8 that bending die is connected with clamp, or regulates by other suitable forms.Bending die can be monoblock type or the split-type that is combined by several connections.
