Bending machine

Abstract

The embodiment of the invention provides a word bending machine which comprises an inner blade, an inner blade base, one or more outer blades, a rotating drive device and one or more lifting drive devices, wherein a discharging slit used for conveying plates is formed in the inner blade; the rotating drive device is used for driving the outer blades to rotate around the discharging slit; the bottom end of the inner blade is detachably fixed on the inner blade base; a base through hole, of which the central axis is parallel to the discharging slit, is formed in the inner blade base; the lifting drive devices are detachably connected with the outer blades respectively, so as to drive the outer blades to penetrate the base through hole and move up and down. Through the adoption of the word bending machine, the problems that the conventional word bending machine is low in production and shaping rate and inflexible in production assembly structure, and a cutter adopted by the conventional word bending machine for bending is high in preparation cost and difficult to demount for replacement are solved.

Description

technical field [0001] The invention relates to the fields of mechanical design and mechanical processing, in particular to a font bending machine. Background technique [0002] A font bending machine is a device that bends a plate into a certain shape and outline, and is widely used in the preparation of advertising fonts or various pattern logos. However, the assembly structure of the font bending machine in the prior art is inflexible, and the preparation cost of the cutting tool for bending and forming is high, and it is not easy to disassemble and replace. [0003] figure 1 Shown is a schematic structural diagram of a font bending machine provided by the prior art. Such as figure 1 As shown, the bending machine includes: an inner knife 11 and a rotatable outer knife 12 arranged outside the inner knife 11 . Wherein, the structure of outer knife 12 is as figure 2 As shown, the outer knife 12 is cylindrical, and a pair of side edges 121 are arranged in the middle. I...
