Description
Technical field
The utility model relates to a kind of swan neck system, especially a kind of elastic modelling quantity according to material and deformation extent, determine the springback capacity of material, by carrying out resilience correction to bent pipe mold, realize the bending radius of bend pipe and bend the numerical controlled bending of pipe device that angle meets product requirement, the specifically accurate bending device of a kind of many bend pipe bendings.
Background technology
Because tube bending process is elastic and plastic deformation process, resilience is there is time bending, causing the problems such as profile angle is little, bending radius is large, pipeline axis is elongated and dihedral angle diminishes, for ensureing the precision that pipe bends, must considering that resilience is on bending the impact caused.When designing bend pipe mould, according to the impact that resilience causes, bend pipe mould being revised, realizing the object of accurate bend pipe.
Utility model content
The purpose of this utility model be for current factory when bending small-diameter, thin-walled bend pipe, the resilience problem of the crooked position existed, design a kind of accurate bending device of many bend pipe bendings can revised resilience and impact, it is by revising according to the theoretical size of bend pipe and springback capacity the mould of bend pipe, ensures that the size of the bend pipe bent meets product size required precision.Thus improve shaping efficiency and the utilization rate of raw materials of product, and improve the productivity effect of product.
The technical solution of the utility model is:
The accurate bending device of a kind of many bend pipe bendings, its feature it comprise wheel mould 1, interior clamping 2, outer clamping 3, guided mode 4 and support fixture 5, described interior clamping 2 is arranged on wheel mould 1, described outer clamping 3 occurs in pairs with interior clamping 2, described guided mode 4 is positioned at the peak place of wheel mould 1, and described support fixture 5 is positioned at the side of guided mode 4; Described radius R ' of taking turns mould 1 is that principal radii R adds Resilience radius correction, and angle of bend A ' adds resilience correction angle for theoretical angle of bend A.
