Embodiment Construction

[0026] Such as figure 2 As shown, the numerical control bending automatic matching method proposed by the present invention is mainly used for the bending processing of sheet metal parts, and the method includes steps 1 to 3, which will be described respectively below.

[0027] Step 1. Create a bending standard library and embed it into the 3D design platform in a parametric form. Bending equipment library, tool library, upper and lower die position library, and bending rule library. The bending equipment library contains several CNC bending machines and the corresponding processing rules of each CNC bending machine. The processing rules include the programming of the CNC bending machine rule. The bending rule library includes: tool combination rules, sorting rules, yield rules, sheet metal material thickness matching rules, bending compensation coefficient table and bending expansion coefficient table. The bending compensation coefficient table should contain different bend...

Abstract

The invention discloses a numerically controlled bending automatic matching method and system. The method comprises the following stepsof S1, establishing a bending standard library; S2, drawing a part in a three-dimensional design platform, acquiring the bending characteristic parameters of the part, and examining whether machining is feasible or not according to whether the bending characteristic parameters of the part are matched with the bending standard library or not; and S3, issuing a part drawing feasible to machine, calling the bending standard library to match a tool automatically according to the bending characteristic parameters of the part to generate a bending CNC program and / or a bending guiding video. The method provided by the invention can achieve numerically controlled bending automatic matching mold programming and outputs the bending guiding video, so that the production efficiency is improved effectively.

Description

technical field [0001] The invention relates to the technical field of numerical control machining, in particular to a numerical control bending automatic matching method and system. Background technique [0002] At present, in the sheet metal processing industry, the CNC bending process usually draws the parts on the 3D design platform, and the bending rationality of the parts is judged by manual review. After the drawing is approved, it is sent to manual programming, and finally the bending process is performed. figure 1 It shows the existing manual matching mold programming process. This method of manually reviewing the bending rationality is very easy to issue drawings with wrong bending designs for production. Errors start from the design source, which seriously affects the production schedule. [0003] In addition, manual programming mainly adopts the following two programming methods: one is that the operator manually combines the tool splicing scheme according to the...
