Problems solved by technology

Flanging parts will spring back during the forming process. Manual hammering to adjust the springback is inefficient, labor intensity is high, and the environment is noisy. Flanging with fixed molds requires corresponding molds to be designed for different products, and the mold utilization rate is low. , the development cost is high, and the production cycle is long; and when the mold is fixed, it is impossible to adjust the amount of compensation for flanging springback, the force is uneven, and the forming accuracy is low

Embodiment Construction

[0019] like figure 1 and figure 2 As shown, this embodiment relates to an adjustable multi-point progressive flanging forming device, including: a pressing mechanism 1, a flexible spring washer assembly 2, a plurality of stacked adjustment rod assemblies 3 and a In the formed six-degree-of-freedom working end 6, wherein: one end of the to-be-formed part 7 is arranged between the pressing mechanism 1 and the flexible spring washer assembly 2, and the flexible spring washer assembly 2 envelops one side of the stacked adjusting rod assembly 3. On the outer surface, the six-degree-of-freedom working end 6 is located at the outer side of the to-be-formed part 7 to bend and deform it.

[0020] like figure 2 As shown, the flexible spring pad assembly 2 includes: at least one steel pad 23 and polyurethane pads 21 correspondingly arranged on both sides thereof, specifically a sandwich structure of polyurethane pad-steel pad-polyurethane pad or polyurethane pad There are two struct...

Abstract

An adjustable multi-point progressive flanging forming device and method, comprising: a pressing mechanism arranged in sequence from top to bottom, a flexible spring washer assembly, a plurality of stacked adjustment rod assemblies, and a six-degree-of-freedom working end for forming, Wherein: one end of the to-be-formed part is arranged between the pressing mechanism and the flexible spring washer assembly, the flexible spring-cushion assembly envelops the outer surface formed by one side of the stacked adjusting rod assembly, and the six-degree-of-freedom working end is located on the outer side of the to-be-formed part. It undergoes bending deformation. The invention changes the change of the curvature of the die surface by adjusting the expansion and contraction of the adjusting rod assembly until the shape of the preset curved surface of the part to be formed; the coordinated control between the adjusting rod assemblies of the present invention realizes the change of the curvature of different die surfaces, and realizes the completion of the same platform. Flange forming of materials of different sizes.

Description

technical field [0001] The invention relates to a technology in the field of sheet metal parts manufacturing, in particular to an adjustable multi-point progressive flanging forming device and method. Background technique [0002] The existing production of flanging parts mainly includes two forming methods: manual hammering and fixed mold flanging. Flanging parts will spring back during the forming process. Manual hammering to adjust the springback is inefficient, labor intensity is high, and environmental noise is high. Using a fixed mold for flanging forming requires corresponding molds for different products, and the mold utilization rate is low. , the development cost is high, the production cycle is long; and the amount of flanging springback cannot be adjusted and compensated when the mold is fixed, the force is uneven, and the forming accuracy is low. SUMMARY OF THE INVENTION [0003] Aiming at the above-mentioned shortcomings of the prior art, the present inventi...
