Cut-off device of metal sheet cut-off machine

Abstract

The invention discloses a cut-off device of a metal sheet cut-off machine. The cut-off device of the metal sheet cut-off machine comprises a cut-off power driving assembly, a cut-off guiding part and a cut-off execution assembly; a motor provides power for the cut-off device integrally; an eccentric wheel on a driving shaft is driven to rotate through driving of synchronous wheels and a synchronous belt; eccentric movement acts on a framework through bearing driving; meanwhile, under the guiding action of the guiding part, a cutter is finally driven to perform vertical linear cut-off movement. By means of the cut-off device of the metal sheet cut-off machine, multiple metal sheets can be cut off at the same time; the cutter is convenient to mount; the work efficiency and cut-off size accuracy are high; cut notches are neat; manual assistance is not needed during cut-off action; control is simple; the cost is low.

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
