Wire cutting wire arrangement mechanism with electrode wire cutting and recovery functions

Abstract

The invention discloses a wire cutting wire arrangement mechanism with electrode wire cutting and recovery functions. The mechanism comprises a wire cylinder mechanism and a wire arrangement mechanism; the wire arrangement mechanism comprises two sets of connecting rod combination mechanisms arranged on the same one plane in a mirror image manner; the connecting rod combination mechanisms comprise manual wire tightening mechanisms, automatic wire tightening mechanisms, slide mechanisms and fixed guide wheels for changing a wire arrangement direction; the wire cylinder mechanism comprises a wire cylinder, guide grooves uniformly distributed in the peripheral direction of the outer wall of the wire cylinder, cutting devices respectively arranged in the guide grooves spaced on the outer wall of the wire cylinder in a radial extending direction of the wire cylinder, and wire collecting devices arranged in the guide grooves between the adjacent cutting devices; the wire collecting devices are sleeved with pressing devices in the axial direction of the wire cylinder; and tightening devices for driving radial movement of the cutting devices and the pressing devices are symmetrically arranged at two ends of the wire cylinder. The wire cutting wire arrangement mechanism comprises a whole set of wire cutting flow as wire penetration, wire tightening and cutting of molybdenum wires after machining, and is optimized to improve the machine tool machining efficiency.

Description

technical field [0001] The invention belongs to the field of wire-cutting machine tools, and in particular relates to a wire-cutting wire-feeding mechanism with the function of cutting and recovering electrode wires. Background technique [0002] Wire cutting electrode wire feeding and tightening is an important link in the wire cutting operation. Its quality directly affects the quality of the processed parts and the cutting speed. There is a close relationship between wire tension and cutting speed in wire cutting. The cutting speed is maximum when the wire tension is moderate. [0003] When wire cutting tight wire, stop the wire at one end of the roller drum, the wire leans against the groove of the wire tightener, use light force to let the wire drum roll from one end to the other, and then wind the excess wire onto the wire drum. Since the molybdenum wire is reciprocating at high speed in forward and reverse directions, there are "tight edge" and "loose edge", that is...

Problems solved by technology

Of course, when the molybdenum wire is very messy and messy on the wire drum, it takes a long time and energy for the operator to complete the molybdenum wire arrangement
