Abstract
A kind of 180 ° of cold-extruded elbow roll moulds,It includes push rod 1,Draw set 2,Draw set fixed station 3,Bed die tool 4,Pipe 5,Disk roller 6,Mould internal shape cavity 8,Disk roller gland 9,Bolt 10 is formed,Pass through rotary disk roller 6 on mould,There is axle 11 at the both ends of disk roller 6,Coordinated by the gap of disk roller gland 9,Disk roller gland 9 is fixedly connected by bolt 10,So that disk roller 6 is rotatably connected with bed die tool 4,Draw set fixed station 3 to be fixedly connected with bed die tool 4,Draw set 2 and coordinate with drawing set fixed station 3 gap,Pipe 5 is put into and drawn in set 2,Then push rod 1 is also placed in and drawn in set 2,Coordinate with drawing 2 gaps of set,Extruding of the push rod 1 by outer active force 7,Pipe 5 is set to enter mould internal shape cavity 8,Pipe 5 starts flexural deformation,Now pipe 5 can drive disk roller 6 to rotate,Until 180 ° of cold-extruded elbow brake formings,This mould structure is reasonable,Frictional resistance is greatly decreased.
Description
Technical field
It the utility model is related to a kind of 180 ° of cold-extruded elbow roll moulds.
Background technology
Elbow angularly divides, have 45 ° and 90 ° 180 ° three kinds it is the most frequently used, at present used in traditional 180 ° of cold-extruded elbows
Mould, bend forming is difficult, and frictional resistance (skin resistance) is very big, and elbow external diameter and bending radius do not reach technological requirement, squeezes
The elbow gone out must do logical ball, shaping process processing, and production efficiency is low, it is impossible to meets companies needs.
The content of the invention
In order to overcome the shortcomings of traditional 180 ° of cold-extruded elbow modules, the technical problems to be solved in the utility model is to pass through mould
The disk roller rotated on tool, traditional 180 ° of cold-extruded elbow modules caused sliding friction in production and application is converted into rolling and rubbed
Wipe, reduce mould internal shape cavity to elbow caused frictional resistance in the fabrication process, so do and more meet mechanics principle.Because
Frictional resistance is greatly decreased, thus the hydraulic press can for avoiding the need for very large-tonnage produce in, 180 ° of cold-extrudeds of heavy wall
Elbow, elbow both ends bore is reached technological requirement, the situation of elliptic aperture will not be formed, without making logical ball, at shaping process
Reason, so as to simplify, improve production efficiency.
Described bed die tool is combined into by the two pieces of decile.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 top view.
Fig. 3 is 3-D view of the present utility model
Embodiment
The above is achieved in that with reference to accompanying drawing, including push rod 1, is drawn set 2, drawn set fixed station 3, bed die tool 4, pipe
Son 5, disk roller 6, mould internal shape cavity 8, disk roller gland 9, bolt 10 are formed, and there is axle 11 at the both ends of disk roller 6, by between disk roller gland 9
Gap coordinates, and disk roller gland 9 is fixedly connected by bolt 10 so that disk roller 6 be rotatably connected with bed die tool 4, draw cover fixed station 3 and
Bed die tool 4 is fixedly connected, and is drawn set 2 and is coordinated with drawing set fixed station 3 gap, pipe 5 is put into and drawn in set 2, then also puts push rod 1
Enter to draw in set 2, coordinate with drawing 2 gaps of set, push rod 1 is made pipe 5 enter mould internal shape cavity 8, pipe by the extruding of outer active force 7
Son 5 starts flexural deformation, and now pipe 5 can drive disk roller 6 to rotate, and pipe 5 continues to bend, and disk roller 6 continues and then to rotate, until
180 ° of cold-extruded elbow brake formings, this mould structure is reasonable, makes pipe 5 is much smoother in the presence of the rotation of disk roller 6 to bend to
Type, frictional resistance is greatly decreased.
Claims (2)
