Metal wire rod precision alignment cutting device and method

Abstract

The invention discloses a metal wire rod precision alignment cutting device and a method. The device comprises a double-layer machine frame. A front end guiding tank, a revolving alignment tank, a traction mechanism, a back end guiding tank, a cutting mechanism and a machinery sizing mechanism are arranged on the top portion of the double-layer machine frame. The revolving alignment tank comprises a revolving alignment straight tank support seat, an alignment guiding tank, a plurality of alignment modules and a protection cover. The traction mechanism comprises a traction mechanism support seat, a servo motor, a driving friction wheel and a driven friction wheel. The cutting mechanism comprises a cutting wheel support frame, an air cylinder, a cutting wheel motor and a slice-shaped cutting wheel. The machinery sizing mechanism comprises a horizontal scale plate, a pressure sensor, an infrared transmitting sensor and an infrared receiving sensor. The method includes the steps that the metal wire rod enters the revolving alignment tank through a front end guiding rank. The metal wire rod is alignmented, tracted, cut and prepared and enters the next working circulation. The metal wire rod precision alignment cutting device and the method is high in automatic degree. The shape of the cut metal line segment and the size precision are high. The cutting opening is smooth, free of deckle edge and free of splitting off. The metal wire rod precision alignment cutting device and the method are strong in practicality.

Description

technical field [0001] The invention relates to the technical field of metal wire processing machinery, in particular to a metal wire precision straightening and cutting device and method. Background technique [0002] The existing straightening and cutting methods for metal wires mainly deal with steel bars and other metal wires with larger diameters, and the processed materials have less hardness, better toughness, longer cutting length, and the cutting method adopts the blade punching type, so As a result, the slit has a beveled edge. For hard and brittle metal wires, the blade punching type can easily lead to slit cracks, and the truncation length error is relatively large. The slit needs to be smoothed in the later stage. The process is complicated and the cost is high, and it cannot meet the requirements of the precision parts industry. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a metal wire precision ...
