Numerical control non-mould molding equipment of sheet metal

Abstract

The invention discloses a digital control dieless former which is directly applied to forming of sheet metals. The digital control dieless former comprises a pedestal and two pairs of upright posts which are arranged on the left and the right of a pedestal respectively, wherein each upright post consists of two post brackets and a top beam; X axial guide rails are arranged on the pedestal; X axial platforms which can move on the X axial guide rails are arranged on the X axial guide rails; Y axial platforms are arranged on the top beams of the two pairs of upright posts; Y axial guide rails are arranged on the Y axial platforms; Z axial main shafts are arranged on the Y axial guide rails; the number of the X axial guide rails is two, and the two X axial guide rails are fixed on the pedestal through H-shaped steel; X axial lead screws are arranged on both insides of the X axial guide rails; the number of the Y axial guide rails is two, and the two Y axial guide rails are fixedly connected to both sides of the Y axial platforms through bolts; and Y axial lead screws are arranged on both insides of the Y axial guide rails. Because the digital control dieless former has a motion mechanism in the X direction, the Y direction and the Z direction and has the function of forming different sheet metals, and the X direction, the Y direction and the Z direction realize triaxial linkage when controlled by a computer, so the digital control dieless former adopts the means of single-point progressive dieless forming, thereby the forming process is highly automatic, the forming flexibility is greatly improved, and the precision level is obviously higher than that of manual forming.

Description

technical field [0001] The invention relates to a three-axis numerical control equipment directly applied to metal plate forming, in particular to a numerical control moldless forming equipment capable of rapidly forming various metal plates within 4mm in thickness. Background technique [0002] The traditional sheet metal forming technology (stamping, etc.) relies on special molds to press and form the sheet on a large stamping machine tool. Due to the complex structure of the mold, high manufacturing costs, long production preparation time, and poor processing flexibility, it is only suitable for large Mass production, such as mass-produced car body panels. For the production of small and medium batches of sheet metal and single-piece trial production, there is currently no reasonable solution in the industry. Therefore, in many small-batch-produced cars, some of the body panels are still formed manually, and the manufacturing accuracy is difficult to control, and some us...

AI Technical Summary

Problems solved by technology

Therefore, in many small-batch-produced cars, some body panels are still formed manually, and its manufacturing accuracy is difficult to control, and some use glass fiber reinforced plastic structures instead of metal sheet metal structures.

For the development of new cars, resin molds are mostly used at home and abroad at present, and the molds and processes are complicated and costly

At present, there is no sheet metal forming technology suitable for small and medium batch production and single-piece trial production in the industry.
