Description
Technical field
The invention belongs to thin-wall pipes bending techniques fields, are related to all thin-wall pipes part bending positioning, anti-deforming structure.
Technical background
There are a large amount of thin-wall pipes bools in Aeronautics and Astronautics, automobile and appliance industry, mostly uses lengthening materials in the tube
Length cuts off deformation section after bending, thus product bending size is inconsistent, and bending force direction has some limitations, and
Production cost and material cost are higher, especially for precious metal material such as non-ferrous metal (aluminium and aluminium alloy, copper and
Copper alloy etc.), titanium alloy, high temperature alloy etc., material cost can be doubled and redoubled；By materials in the tube on pipe bending mechanism be bent when by
Power analysis, for materials in the tube maximum shape by pulling force, it is the power F that slides axially that interior shape, which is pressurized,y, in order to overcome the power, need to apply materials in the tube
Radial pressure Fn, work as FnWhen crossing the deformation compressive resistance that can bear greater than materials in the tube, then materials in the tube are weighed wounded or are deformed；Work as Fn× μ < Fy
When, product orientation fails and size is unstable.
Summary of the invention
The present invention be prevent to solve wall light wall pipe pipeline fitting in bending materials in the tube blank deform because clamping force is improper or
It is weighed wounded, and the technical problem that product orientation fails, size is unstable.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme:
A kind of 7 collet of pipe bending mechanism for thin-walled tube bending blank includes one to be connected with pipe bending mechanism 7 by connecting pin 5
Determine flitch 1；Described to determine flitch 1 equipped with snap-gauge 2, determining above snap-gauge 2 is additionally provided with hook 3 and hinge pressing plate on flitch 1
4；The hook 3 is connect with hinge pressing plate 4 by helical spring；Kidney slot is offered in the hinge pressing plate 4.
The snap-gauge 2 is two pieces.
By adopting the above technical scheme the utility model has the advantages that
It is the configuration of the present invention is simple, light and handy, it is easy to process and low in cost, it is applied widely;Not only solves thin-wall pipes clamping
Anti-deformation and orientation problem, while the utilization rate of thin-wall pipes material is improved to the maximum extent, reduce production cost.

Specific embodiment
In conjunction with Fig. 1 example, emphasis is further described the present invention.
The present invention improves material use to guarantee that thin-walled blank 6 when by bending, is not deformed because clamping is improper
Rate, to reduce production cost.By force analysis of the materials in the tube when being bent on pipe bending mechanism 7, materials in the tube maximum shape by pulling force,
It is the power F that slides axially that interior shape, which is pressurized,y, in order to overcome the power, need to apply radial pressure F to materials in the tuben, work as FnIt crosses and is greater than materials in the tube institute
When the deformation compressive resistance that can be born, then materials in the tube are weighed wounded or are deformed；Work as Fn× μ < FyWhen, product orientation fails and size is unstable
It is fixed.
As shown in fig. 1, thin-walled blank 6 in pipe bending mechanism 7 with determining flitch 1 and snap-gauge 2 is positioned, materials in the tube bending
After R and 6 base diameter of thin-walled blank determine, symmetrically it is pressed on by two pieces snap-gauge 2 and determines to pass through hinge pressing plate 4 and hook 3 in 1 slot of flitch
By required FnIt passes radial in thin-walled blank 6.Radial force FnSize can be finely tuned by kidney slot size e in hinge pressing plate 4, spiral
Spring designs power F and radial force FnRelationship be Fn=F × cos θ, soket head cap screw is as auxiliary binder component in figure.
Thin-walled blank 6 needs to overcome axial force F in bendingy, and Fy=Fn× μ, Fn=F × cos θ is wherein:
F-spring works pulling force (N) Fy- the power that slides axially (N) Fn- radial pressure (N) μ-coefficient of friction θ-initially divides
Power angle, in order to meet radial component FnThin-walled blank 6 is not set to clamp deformation, while fully considering spring works pulling force F,
Waist type groove is added in hinge pressing plate 4, and (size e), reaches balanced F with this in Fig. 1nThe function of component.
Thin-walled blank 6 positions in determining flitch 1 and snap-gauge 2 in the present invention, manual hinge pressing plate 4, makees in helical spring
Under, by component FnSnap-gauge 2 is fastened by hook 3, the positioning of thin-walled blank 6 is enable to clamp.It is bent the product finished, is unclamped
Hinge pressing plate 4 separates hook 3 with snap-gauge 2, so that product be made to separate.
The present invention is suitable for Aeronautics and Astronautics, automobile and appliance industry thin-wall pipes bending angle≤180 ° R and U-tube
The bending of road part.
