Problems solved by technology
[0002]The electrode wire of the EDM wire-cut electric spark discharge machine is discharged through the forward and reverse rotation of the wire drum. The uneven wire arrangement caused by the wire rod) during operation will lead to insufficient tension of the electrode wire, which will easily cause dark lines and horizontal stripes on the surface of the processed parts, which will affect the quality of cutting parts. For this reason, we propose a Self-clearance mechanism for wire feeding and intelligent wire drum seat containing it

Embodiment Construction
[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0035] like Figure 1-11 As shown in the figure, a self-anti-backlash mechanism for moving a wire includes a screw shaft 18, a screw thread screw socket 16 and a screw nut 15. The screw nut 15 is fixed on the left end of the moving plate 14, and the screw thread Limiting posts 161 are provided on both sides of the upper end of the rod socket 16, and U-shaped grooves 162 are provided between the two sets of limiting posts 161;

The wire conveying self-clearance-eliminating mechanism comprises a lead screw shaft, a wire conveying lead screw nut base and a lead screw nut, and the right end of the lead screw shaft penetrates through the lead screw nut and a movable plate and then extends out of a U-shaped groove; first quick-release bases are fixed to the two ends of the movable plate, first spring bases are installed at the right ends of the first quick-release bases, second quick-release bases are fixed to the surfaces of the left ends of the limiting columns, second spring bases are installed at the left ends of the second quick-release bases, polished rods are arranged in the middles of the left ends of the second spring bases, and springs are connected to the polished rods in a sleeving mode. According to the invention, through the arrangement of the spring, the arrangement of the electrode wires on the wire cylinder is tighter and more uniform, the gaps of the wire arrangement of the electrode wires are eliminated, the electrode wires are tensioned, and the wire cylinder supporting plates are connected to the guide rails on the two sides of the upper end of the wire cylinder seat body in a sliding manner, so that the wire cylinder driven by the motor is connected between the left wire conveying cylinder seat and the right wire conveying cylinder seat. In this way, the cutting precision of the electrode wire on the workpiece is improved, and dark fringes and transverse stripes on the surface of a machined part are improved.
Description
technical field [0001] The invention belongs to the technical field of EDM wire cutting electric spark discharge machines, and in particular relates to a wire transporting self-anti-backlash mechanism and an intelligent wire drum seat containing the same. Background technique [0002] The electrode wire of the EDM wire cutting EDM discharges the wire through the forward and reverse rotation of the wire drum. At present, the transmission screw (excluding the ball screw) in the wire conveying mechanism on the market causes uneven wire arrangement during operation. It will lead to insufficient tension of the electrode wire, and it is easy to produce dark lines and horizontal stripes on the surface of the machined parts, which affects the quality of the cutting of the parts. For this reason, we propose a self-removing wire transport mechanism and an intelligent wire drum seat containing it. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a ...
