Abstract

The invention discloses an application method of a bending machine die capable of machining a multi-radian circular face, and belongs to the field of bending machines. The application method solves the problem that an existing bending machine die cannot adapt to machining of workpieces of different sizes or the application range is narrow. The die comprises an upper die body and a lower die body. The upper die body comprises an upper die clamping part and an upper die cutter head. The lower die body comprises a lower die forming body and a lower die base. The cross section of the bottom of the upper die cutter head is in an arc shape. A first groove is formed in the lower die base, and a second groove is formed in the bottom of the first groove. The lower die forming body is arranged on the first groove. An arc groove is formed in the upper surface of the lower die forming body. A buffering cavity is formed in the middle portion of the lower die forming body, an arc protrusion is arranged on the lower surface of the lower die forming body, and the lower die forming body is made of polyurethane. A third groove concaved upwards is formed in the bottom of the lower die base. The application method can adapt to machining of workpieces with different radian radii, stability is good, the machining precision is high, and the workpiece surface quality is high.

Description

[0001] This application is a divisional application of the invention application titled "A Bending Machine Die Capable of Machining Multi-Radian Circular Surfaces and Its Application Method", the application number is 2014107891666, and the application date is December 18, 2014. technical field [0002] The invention belongs to the field of bending machines, and in particular relates to a method for using a bending machine mold capable of processing multi-arc circular surfaces. Background technique [0003] The bending machine can process workpieces with different size requirements by changing molds of different shapes and specifications. Once the shape and size of the general mold are determined, it can only process workpieces of one shape and size. In actual work, many workpieces are only very small. Small dimensional changes, so changing the mold is a waste of production time, and the production of the mold causes a large cost investment. It is urgent to produce a mold tha...
