Problems solved by technology

The core system of WEDM includes a wire-feeding module. The length and inclination of the cutting object section of the existing wire-cutting wire-cutting module require multiple adjustment mechanisms to adjust separately, and the reciprocating wire-feeding of the cutting wire requires two winding wires. The disks are driven and reversed separately, the overall structure is complex, the volume is large, the operation is inconvenient, the production cost and the use cost are high

Embodiment 1

[0036] When cutting small workpieces, refer to figure 1 , when the cutting wire length of the cutting object section meets the requirements, the motor controller controls the wire wheel drive device 3 to drive the W-shaped wire wheel 2 to rotate to realize the reciprocating wire feeding of the cutting wire, the copper nose is connected to the external power line, and the current is introduced The power line 1 can generate electric discharge with the workpiece to be processed to realize wire electric discharge cutting.

Embodiment 2

[0038] Comparative example 1, when needing to cut bigger size object, refer to Figure 6-8 , then by loosening the butterfly bolt 5-3, turning and rotating the upper arm 5-2 to the required angle, and then using the butterfly bolt 5-3 to lock and fix it with the fixed lower arm 5-1, so that the opened scissors The length of the cutting wire 1 between the tension adjustment mechanism 5 (1 section of cutting wire between the front T-shaped guide wheel 7-8 and the right rear T-shaped guide wheel 6-5) meets the workpiece for cutting purpose, when the cutting wire 1 needs to be tensioned , through the limit butterfly screw 7-4 to unscrew the tensioning arm 7-1 along the threaded hole in the middle of the screw base 7-6, the tensioning arm 7-1 is driven by the torsion spring 7-3 Turn around the connecting shaft 7-5 to pull the cutting wire 1 to make it tense, and then control the wire wheel drive device 3 to drive the W-shaped wire wheel 2 to rotate through the motor controller to r...

Abstract

The invention discloses a foldable wire electric discharge cutting module. The two ends of the cutting wire are respectively wound in the left and right grooves of the W-shaped wire wheel, and the middle part of the cutting wire is wound on the scissors-type tension adjustment mechanism. The wheel driving device drives the cutting wire to reciprocate by driving the W-shaped wire wheel to rotate. The left cutting wire is wound on the cutting wire tensioning mechanism, and the cutting wire tension is adjusted through the forward and reverse movement of the cutting wire tensioning mechanism. The cutting wire on the right side is wound on the conductive mechanism, and the current is introduced through the conductive mechanism to generate discharge with the workpiece to be processed. The adapter plate is installed on the machine tool and is rotatably connected to the fixed lower arm. The invention drives the cutting wire reciprocatingly through a single wire wheel driving device, with low cost and simple operation. The length and inclination of the cutting wire can be adjusted through the scissors-type tension adjustment mechanism and the rotatable cooperation with the rotating plate. It is suitable for It has a wide range, and the scissors-type tension adjustment mechanism can be folded and stored, which is small in size and saves space.

Description

technical field [0001] The invention belongs to the technical field of wire electric discharge cutting devices, and in particular relates to a foldable wire electric discharge cutting module. Background technique [0002] Wire-cut electric discharge machining is a processing technology that uses electric spark discharge to cut and shape workpieces. It has no macroscopic force in the processing process and ignores the hardness and toughness of materials. It is a research hotspot in the field of electrical discharge machining. The core system of WEDM includes a wire-feeding module. The length and inclination of the cutting object section of the existing wire-cutting wire-cutting module require multiple adjustment mechanisms to adjust separately, and the reciprocating wire-feeding of the cutting wire requires two winding wires. The discs are separately driven and reversed, and the overall structure is complex, bulky, inconvenient to operate, and the production cost and use cost...
