Description

Technical Field

[0001] This utility model relates to the technical field of fast wire EDM machine tools, and in particular to an adjustable wire frame for a fast wire EDM machine tool. Background Technology

[0002] Fast wire EDM machines, indispensable processing equipment in mold manufacturing, precision machining, and other fields, play a crucial role in numerous industries due to their unique advantage of processing conductive materials with various complex shapes. In the mold manufacturing industry, they are widely used to manufacture cavities and cores for injection molds, stamping dies, and other types of molds, providing precise mold assurance for product molding. In the aerospace field, they are used to process components with complex shapes and high precision requirements, such as engine blades and aircraft brackets. In the electronics manufacturing industry, they can process tiny precision parts, meeting the miniaturization and high-precision development needs of electronic products. With the continuous development of the manufacturing industry, higher demands are being placed on the processing accuracy and processing range of fast wire EDM machines.

[0003] Traditional fast-wire EDM machines mostly use a fixed wire carriage structure, making it difficult to change the cutting angle of the electrode wire once determined. This is extremely limiting when facing diverse machining needs. For example, when machining workpieces with inclined surfaces or multi-angle contours, a fixed-angle wire carriage cannot meet the machining requirements, leading to complex machining processes and even making it impossible to complete the machining of certain specially shaped workpieces. This severely restricts the application range and machining efficiency of the machine tool. Therefore, an adjustable wire carriage for fast-wire EDM machines is proposed. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide an adjustable wire holder for a fast wire EDM machine, thereby solving the problem mentioned in the background art that the wire holder structure of traditional fast wire EDM machines is mostly fixed, and the cutting angle of the electrode wire is difficult to change once determined. This makes it extremely passive when facing diverse processing needs.

[0014] (III) Beneficial Effects

[0015] This utility model provides an adjustable wire frame for a fast wire EDM machine, which has the following advantages:

[0016] 1. The adjustable wire frame of this fast wire EDM machine tool, through the setting of the angle adjustment mechanism, allows the hydraulic rod on the back of the support frame to be activated according to actual needs during use. The hydraulic rod extends and retracts, driving the fixed joint connected to the end and the support frame installed on one side of the fixed joint to adjust the angle, thereby adjusting the angle of the electrode wire installed on the surface of the support frame. This achieves the effect of multi-angle cutting of the workpiece. The operator can flexibly adjust the angle of the electrode wire according to actual needs, effectively improving the efficiency of workpiece processing.

[0017] 2. The adjustable wire frame of this fast-wire EDM machine, through the setting of the length adjustment mechanism, can start the drive motor inside the motor box when cutting workpieces of different thicknesses. The drive motor drives the positive and negative lead screws at the end to rotate, thereby causing the two threaded plates connected by threads on the surface of the positive and negative lead screws to move relative to each other. This allows the length of the electrode wire installed on the top of the threaded plate to be adjusted. With the help of the scale installed on the surface of the guide plate, the operator can intuitively observe the length of the electrode wire exposed in the external environment, thereby facilitating the cutting of workpieces of different thicknesses and improving the flexibility and convenience of the equipment in the processing process.
