Description

Technical Field

[0001] This utility model relates to the field of wire cutting technology, specifically to a novel wire-knotting mechanism. Background Technology

[0002] Wire EDM (Electrical Discharge Machining) is a branch of electrical discharge machining that uses a wire electrode (molybdenum wire, copper wire, galvanized wire) to cut the workpiece by spark discharge. In wire EDM, the relative movement between the workpiece and the electrode wire is controlled digitally. It is commonly used to process high-hardness materials, microstructures, complex shapes, high-precision dimensional parts, and high-surface-quality parts. Currently, wire EDM machines use a method where a pin is inserted into the clamping assembly to form the wire, resulting in impact between the pin and the clamping assembly. This invention provides a simpler and more stable and reliable technical solution for wire forming. Summary of the Invention

It is a new filament-forming technology solution. The method of using a stop block to drive the pressure plate makes the pressure plate open and close on the roller, which avoids the collision between components in the prior art and improves the filament-forming effect and product life.

[0013] Figure 1 This is a schematic diagram of the structure of a novel filament-forming mechanism according to this utility model. Detailed Implementation

[0014] Example

[0015] like Figure 1 As shown, a novel filament-forming mechanism includes a base plate 1, a support frame 2 on the base plate 1, a roller 3 mounted on the support frame 2, a sliding ring 5 mounted on the roller 3, the roller 3 and the sliding ring 5 connected by a ball 4, a connecting block 6 fixed on the sliding ring 5, the connecting block 6 being rotatably connected to a pressure plate 7, a stop block 9 on the pressure plate 7, the stop block 9 and the connecting block 6 being connected by a spring, the connecting block 6 having a circular groove at the spring connection point, one end of the spring being placed in the circular groove, and a telescopic device on the base plate 1, the telescopic device being able to contact, push, and separate from the stop block 9.

[0016] The telescopic device includes a motor 80, whose rotating shaft is connected to a telescopic block 81 via a lead screw. The telescopic block 81 is slidably connected to a base plate 1. One end of a connecting rod 82 is fixed to the base plate 1, and the other end of the connecting rod 82 is located on the left side of the telescopic block 81. A spring column is provided on the connecting rod 82, which is connected to a return spring 83. The return spring 83 is connected to the motor 80. The telescopic block 81 can be pressed and pushed and can be separated from the connecting rod 82. A toggle block is provided on the connecting rod 82, which can be pressed and pushed and can be separated from a stop block 9. A position sensor is provided at a corresponding position on the telescopic block 81, which is mounted on the base plate 1. A sensing plate is provided on the sliding ring 5, and a drive sensor is provided on the support frame 2. When the sensing plate rotates to the position of the drive sensor, the two match and trigger the drive sensor to emit a signal.

[0017] Working principle: As the roller 3 rotates, the actuating block separates from the stop block 9, and the pressure plate 7 presses against the surface of the roller 3. The sliding ring 5 remains stationary relative to the roller 3, meaning the sliding ring 5 rotates together with the roller 3. When wire forming is required, the wire feeding mechanism preceding this process sends an electrical signal to the motor 80. The motor 80 then activates the signal to drive the sensor. When the drive sensor detects the position of the sensing plate, it sends a signal to the motor 80. The motor 80 drives the telescopic block 81 to press against the connecting rod 82 to the left. The connecting rod 82 then drives the stop block 9 to the left, thereby opening the pressure plate 7 and creating an angle between the pressure plate 7 and the surface of the roller 3, allowing the molybdenum wire to pass through. The wire is fed between the pressure plate 7 and the surface of the roller 3. At this time, the sliding ring 5 slides on the roller 3, that is, the sliding ring 5 is in a brief static state relative to the base plate 1. After 1 second of static state, the motor 80 drives the telescopic block 81 to return to the right, and the return spring 83 drives the connecting rod 82 to return to the right. Once the actuating block separates from the stop block 9, the position of the telescopic block 81 is just detected by the position sensor. At this time, the position sensor sends information to the motor 80, and the motor 80 will no longer accept the signal from the drive sensor. The pressure plate 7 clamps the molybdenum wire and continues to press it onto the surface of the roller 3 and rotates with the roller 3 to realize the molybdenum wire spun operation.

[0018] This utility model has a simple structure and its performance is more reliable and superior than traditional methods. It is a new filament-forming technology solution. It uses a stop block to drive the pressure plate so that the pressure plate opens and closes on the roller, avoiding the collision between components in the prior art, and improving the filament-forming effect and product life.
