Description

Technical Field

[0001] This utility model relates to the technical field of wire feed limiting devices, and in particular to a wire feed limiting device for a wire EDM machine. Background Technology

[0002] The wire feed limiting device of a wire EDM machine is a key component that ensures the metal wire runs accurately and stably on a predetermined trajectory during the wire EDM process, avoiding excessive stretching or knotting of the wire, thereby improving processing accuracy and extending the service life of the wire. In order to ensure the accuracy of cutting, it is necessary to design a wire feed limiting device for a wire EDM machine.

[0003] Existing wire feeding limit devices have high precision requirements for wire cutting. To achieve high-precision limiting, encoder limiters can be installed on the existing devices. The encoder can monitor the number of rotations and angles of the motor or wire drum in real time. By comparing the encoder with the parameters preset by the machine tool control system, when the wire drum rotates to the set wire feeding limit position corresponding to the number of rotations or angles, the control system issues a command to stop the motor, thus achieving precise wire feeding limit. Although existing wire feeding limit devices achieve high-precision limiting using various sensors, the installation and maintenance procedures are relatively cumbersome and complex. Installing a device that can be easily disassembled on the sensor improves the simplicity of device installation and maintenance. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This utility model provides a wire feeding limit device for a wire EDM machine, which has the following advantages:

[0016] 1. The wire feeding limit device of this wire EDM machine, through the setting of the limit mechanism, when the device is about to cut, put the external material to be cut into the cutting box, adjust the cutting angle and fix it. Then the cutting column slides, and the cutting head is installed at the bottom of the cutting column. The molybdenum wire is connected to the bottom of the cutting head. The molybdenum wire is energized to cut the external material according to the set program trajectory. Since an encoder is installed inside the cutting column, the encoder can monitor in real time and perform limit, ensuring the cutting accuracy and playing a precise limit role. This avoids the impact of the lack of limit on the cutting accuracy and the reduction of the quality of the cut external material.

[0017] 2. The wire feed limit device of this wire EDM machine, through the setting of the disassembly mechanism, ensures normal cutting by real-time monitoring of the encoder inside the cutting column during cutting, while the cutting column is moving. However, due to the long-term operation of the cutting work, the encoder or internal parts may be damaged, requiring disassembly, replacement, and maintenance. However, since the encoder is equipped with magnetic rings A and B on the back, it is easily disassembled by magnetic attraction, which facilitates disassembly and maintenance. This avoids the cumbersome and complicated steps that would result in the lack of a disassembly function, increasing maintenance time and costs. Attached Figure Description

[0027] Please see Figure 1 The right side of the cutting box 2 is rotatably connected to the door 9, and the left side of the surface of the door 9 is fixedly connected to the handle 10. The cutting box 9 is designed to facilitate operation and shifting cutting.

[0028] Please see Figure 1 The encoder 501 is electrically connected to the PLC controller 11 via a power cord. The top of the PLC controller 11 is rotatably connected to a rotating connector 12. Through the settings of the PLC controller 11, it plays a role in precise control.

The cutting head 8 is installed at the bottom of the cutting column 3. The molybdenum wire 17 is connected to the bottom of the cutting head 8.
