Cutting device for sheet metal cutting machine

Abstract

The invention discloses a cutting device of a metal sheet cutting machine, which comprises a cutting power transmission assembly, a cutting guide part and a cutting execution assembly. The whole cutting device is powered by a motor, and driven by a synchronous wheel and a synchronous belt to drive the eccentric on the transmission shaft. The wheel rotates, and the eccentric motion acts on the frame body through the bearing transmission. At the same time, under the guidance of the guide assembly, the cutter is finally driven to perform vertical cutting motion. The present invention can cut off a plurality of sheet metals at the same time, and the cutting tool is easy to install, has high working efficiency, high cutting dimension precision, neat fracture, no manual assistance for cutting action, simple control and low cost.

Description

technical field [0001] The invention relates to a cutting device of a metal sheet cutting machine, which belongs to the technical field of metal material cutting machines. Background technique [0002] The cutting device is an important component of the sheet metal cutting machine. At present, the metal cutting machines on the market are mainly divided into two categories, one is the metal cutting machine for cutting round bars, this type of cutting device often uses the rotation of the cutter to cut off the round bars; the other is the cutting machine for general thin plates , such as shearing machines, punching machines, etc. in the sheet metal process, their cutting devices often have large structures, which are suitable for cutting large pieces of sheet metal with a certain thickness and where there is no high requirement for the quality of the cut. For metal sheets with very small thickness, such as alloy molybdenum sheets with a thickness of only 0.02mm and high tough...

At present, the metal cutting machines on the market are mainly divided into two categories, one is the metal cutting machine for cutting round bars, this type of cutting device often uses the rotation of the cutter to cut off the round bars; the other is the cutting machine for general thin plates , such as shearing machines, punching machines, etc. in the sheet metal process, their cutting devices often have large structures, which are suitable for cutting large pieces of plate metal with a certain thickness and where there is no high requirement for the quality of the cut

For metal sheets with very small thickness, such as alloy molybdenum sheets with a thickness of only 0.02mm and high toughness in anti-theft acoustic and magnetic labels, general-purpose metal cutting machines cannot meet the requirements, because the cutting knife and the fixed static knife There is a certain movement gap between them, so that the general-purpose cutting machine cannot cut metal sheets with a thickness of tens of microns
