Problems solved by technology
[0002] In the feed mechanism of the existing multi-wire cutting machine, the feed servo motor drives the ball screw through the synchronous belt drive to drive the feed slide to realize the feed. Because the center of gravity of the feed slide has a large overhang relative to the horizontal guide rail surface , which in turn leads to a large amount of horizontal deformation on both sides of the feed slide during the feeding process, which affects the subsequent machining accuracy

The invention provides a feed mechanism for a multiline cutting machine. By the feed mechanism, deformation on two sides of a feed sliding seat is small in the feeding process of the feed sliding seat, so subsequent machining accuracy is ensured. The feed mechanism comprises a base and the feed sliding seat, wherein the feed sliding seat is provided with a ball screw; a driven belt wheel is sleeved at the driving end of the ball screw and is connected with a driving belt wheel by a synchronous belt; the driving belt wheel is connected with a planetary speed reducer; the planetary speed reducer is connected with a servo motor; and a linear guide rail is arranged on the reverse side of the feed sliding seat and is fastened on the base. The feed mechanism is characterized in that: balanced air cylinders are symmetrically arranged on two lateral surfaces of the feed sliding seat; cylinder sleeves of the balanced air cylinders are fastened on two lateral surfaces of the feed sliding seat; and air cylinder rods of the balanced air cylinders butt against the position, which are exposed out of the two sides of the feed sliding seat, of the base.
Description
technical field [0001] The invention relates to the technical field of multi-wire cutting machine structure, in particular to the feeding mechanism of multi-wire cutting machine. Background technique [0002] In the feed mechanism of the existing multi-wire cutting machine, the feed servo motor drives the ball screw through the synchronous belt drive to drive the feed slide to realize the feed. Because the center of gravity of the feed slide has a large overhang relative to the horizontal guide rail surface , which in turn leads to a large amount of horizontal deformation on both sides of the feed slide during the feeding process, which affects subsequent machining accuracy. Contents of the invention [0003] In view of the above problems, the present invention provides a feed mechanism for a multi-wire cutting machine, which makes the deformation on both sides of the feed slide seat small during the feeding process of the feed slide seat, ensuring subsequent machining...
