Sheet Metal Cutting Machine

Abstract

The invention discloses a metal sheet cutting machine, which includes an automatic feeding part and a cutting part. The automatic feeding part is driven by a servo motor through a synchronous wheel and a synchronous belt to drive the feeding rubber roller and the pressing roller to rotate precisely according to the feeding length; The metal flakes in the middle are accurately conveyed forward under the guidance of the feeding guide assembly to complete the automatic feeding function of the cutting machine. The cutting parts are powered by the motor, and after being driven by the synchronous wheel and synchronous belt, the eccentric wheel on the transmission shaft is driven to rotate, and the eccentric The movement acts on the frame body through the bearing transmission, and at the same time, under the guidance of the guide assembly, it finally drives the cutter to move up and down in a straight line, thereby cutting off the metal sheet. The invention can automatically feed and cut a plurality of thin metal strips at the same time, has high working efficiency, easy installation of knives, high length precision after cutting, and neat fractures.

Description

technical field [0001] The invention relates to a metal sheet cutting machine, which belongs to the technical field of metal material cutting machines. Background technique [0002] The metal cutting machine is mainly composed of feeding parts and cutting parts in function. At present, there are basically two types of feeding mechanisms for metal cutting machines on the market. One is the reciprocating clamping feeding type, which uses a pneumatic linear reciprocating clamping device to drive the metal bar to achieve feeding. The other is the roller type, in which the bar is fed by the intermittent motion of three rollers that are not in a straight line. At present, the cutting parts of metal cutting machines on the market often use the rotation of the cutter to cut the round bar material or use the relative slip shearing structure to cut off large pieces of sheet metal with a certain thickness. In this way, for extremely thin strip-shaped metal sheets (such as the alloy m...

Problems solved by technology

In this way, for an extremely thin strip metal sheet (such as the alloy molybdenum sheet in the anti-theft acoustic and magnetic label, the thickness is only 0.02mm, and the width is about 6mm), its weight per unit length is not only much lighter than the metal bar, but also more durable. It has strong flexibility, so the clamping and roller feeding mechanisms commonly used in the market are not applicable, and the cutting parts of the general metal cutting machine are due to the gap between the cutting knife and the fixed knife. A certain movement gap makes it impossible for a general-purpose cutting machine to cut the above-mentioned extremely thin and tough metal sheets
