Flexible bar cutting machine

Abstract

The invention discloses a flexible bar cutting machine which is a high precision automatic cutting device for the cylindrical surface of the two ends of a bar with certain rigidity. The flexible bar cutting machine comprises a feeding system, a jacking system and a rolling-cutting system. A cam disk on a first camshaft is driven to rotate by a motor of the feeding system, and a push plate is driven by the cam disk for achieving forward feeding, so that the bar falls into a V-shaped groove; a cam and the V-shaped groove are driven by a second camshaft to move up and down; the rolling-cutting system comprises a cutting table and a rolling plate, and the cutting table is provided with blades of which the distance and inclination can be regulated; the bar is driven by the rolling plate under the driving of a crank to roll forwards; when the bar is rolled to come into contact with the blades, the end starts to cut; and the bar is continuously rolled for a circle so that the end cutting is finished. The three transmission systems can be reset automatically, and the reciprocating end cutting is achieved. The pressure of the rolling plate is adjustable, and the problems that the bar is soft and liable to deform during clamping, and the cutting accuracy of the end face is low are solved; the structure is simple, and the flatness of the cut end face and the cutting accuracy requirement can be better ensured.

Description

technical field [0001] The invention relates to a flexible bar material cutting machine, in particular to a device specially used for cutting flexible bar material, and belongs to the technical field of mechanical processing equipment for special materials. Background technique [0002] At present, the more common bar end cutting devices in the mechanical field generally use rigid metal bars or profiles as processing materials, and the cutting methods are mostly completed by special metal cutting machines. Due to the particularity of the material, the flexible bar is easy to deform when clamping, and the end face cannot be guaranteed to be even when cutting with a tool. waste; on the other hand, there are few end-cutting devices dedicated to flexible rods on the market, and most of them cannot guarantee the cutting accuracy. Therefore, it is necessary to invent a high-precision end-cutting device for flexible materials to solve the problem of easy deformation of materials ,...
