Description

Technical Field

[0001] This utility model relates to the field of wire cutting machine technology, specifically to an automatic wire take-up device. Background Technology

[0002] A wire EDM machine mainly consists of three parts: the machine tool, the CNC system, and the high-frequency power supply. The CNC system comprises a microcontroller, a keyboard, and a frequency conversion detection system, and has key functions such as gap compensation, linear interpolation, circular interpolation, and automatic wire breakage handling. It can cut materials such as high-strength, high-toughness, high-hardness, high-brittleness, and magnetic materials, as well as precision, small, and complex-shaped parts.

[0003] For example, a wire cutting device with automatic wire threading, application number CN202310203342.2 and authorization announcement date of 20231027, includes a machine tool body; a wire storage mechanism for winding and unwinding wire electrodes, the wire storage mechanism including a wire storage drum, the outer wall of the wire storage drum being provided with a clamping component for fixing the end of the wire electrode; a movable tube wire threading mechanism for threading the wire electrode, the movable tube wire threading mechanism having a movable receiving tube near the end of the wire storage drum, the receiving tube being hollow and capable of threading the wire electrode; when the wire storage drum rotates to a preset position, the end of the receiving tube can be translated and act on the clamping component to make it open; when the receiving tube separates from the clamping component, the clamping component returns to the clamping state and clamps and fixes the end of the wire electrode; and a clamping and feeding mechanism for clamping and feeding the wire electrode forward or backward. The movable receiving tube, together with the clamping components that can open and close, enables automatic feeding, clamping, and unloading of wire electrodes under the clamping action of the clamping mechanism, achieving automated operation and significantly improving processing efficiency.

[0004] For example, a method for automatic wire threading and unthreading in wire EDM, with application number CN202310423717.6 and authorization announcement date of 20231013, is used in an automatic wire EDM threading and unthreading device. The device includes a machine body, a threading mechanism, a wire feeding mechanism, a wire spool, a constant tension adjustment mechanism, and a controller, all mounted on the machine body. The constant tension adjustment mechanism includes a tension sensor and a tension wheel. The tension sensor detects the tension of the electrode wire, and the tension wheel can move up and down to adjust the tension of the electrode wire. A wire clamping mechanism is provided on the wire spool. This invention can achieve automatic wire threading and unthreading, with a high degree of automation, good threading and unthreading effect, and improved processing efficiency.

[0005] Most wire EDM machines still use manual wire clamping for wire take-up, which prevents automatic wire take-up and adds an extra step for the user. Some methods involve forcibly inserting a feed tube between the spring and the take-up spool to open the spring and clamp the wire. However, this method causes significant wear and tear on the equipment, including the feed tube, elastic clamps and guide components, and the wire spool. Because the elastic clamps are forcibly opened, these structures experience substantial wear and require frequent maintenance, potentially affecting normal machine operation or preventing automatic wire take-up. Furthermore, the feed tube's transmission structure is a separate component; in mechanics, more complex structures can lead to more problems. Utility Model Content

[0006] The purpose of this invention is to provide an automatic wire take-up device to overcome the aforementioned shortcomings in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automatic wire take-up device includes a cutting wire, a wire feeding tube, and a take-up cylinder, characterized in that: the take-up cylinder is provided with a cutting wire guiding assembly, the cutting wire guiding assembly includes a guide tube, the guide tube is arranged in an arc shape and hollow, the guide tube has a cutting wire inlet and a cutting wire outlet, the direction of the cutting wire inlet and the direction of the cutting wire outlet are not parallel and are adjacent.

[0009] Preferably, the cutting wire guide assembly is fixed to the surface of the take-up drum.

[0010] Preferably, the cutting wire guide assembly is part of the take-up spool.

[0011] Preferably, the cutting wire inlet is provided with a guide nozzle.

[0012] Preferably, the guide nozzle gradually decreases in size from the edge furthest from the cutting wire inlet until it is the same size as the cutting wire inlet.

[0013] Preferably, the guide nozzle is conical or trumpet-shaped.

[0014] In the above technical solution, the automatic wire take-up device provided by this utility model has the following advantages:

[0015] (1) In the automatic wire take-up technology designed in this utility model, after the wire feeding tube feeds the cutting wire into the cutting wire inlet, the cutting wire head is sent out from the cutting wire outlet and crosses with the cutting wire body. While the wire is continuously fed, the take-up drum rotates, wraps the cutting wire around the take-up drum, and presses down the cutting wire head to achieve the purpose of automatic wire take-up. This utility model does not add a transmission mechanical structure, which greatly reduces the frequency of mechanical maintenance and the occurrence of failures. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figures 1-2 As shown in the figure, an automatic wire take-up device provided in this utility model includes a cutting wire 5, a wire feeding tube 4, and a take-up cylinder 1. The take-up cylinder 1 is provided with a cutting wire guide assembly 2, which includes a guide tube 3. The guide tube 3 is arc-shaped and hollow, and has a cutting wire inlet 6 and a cutting wire outlet 7. The direction of the cutting wire inlet 6 is not parallel to the direction of the cutting wire outlet 7, but they are adjacent to each other. The cutting wire guide assembly 2 is fixed to the surface of the take-up cylinder 1. The cutting wire guide assembly 2 is part of the take-up cylinder 1. The cutting wire inlet is provided with a guide nozzle 8. The edge of the guide nozzle 8 away from the cutting wire inlet 6 gradually decreases in size until it is the same as the cutting wire inlet 6. The guide nozzle 8 is conical or trumpet-shaped.

[0024] like Figure 1As shown in the embodiment of this utility model, an automatic wire take-up device is provided. The take-up cylinder 1 is provided with a cutting wire guide component 2. The cutting wire guide component 2 is part of the take-up cylinder 1. Its design scheme is to integrate the guide tube 3 with the take-up cylinder. Since the take-up cylinder 1 is circular, the outer wall of the take-up cylinder 1 is set into an arc-shaped hollow state. The positions of the cutting wire inlet 6 and the cutting wire outlet 7 are set in the same way. This design scheme further reduces the structure, and the surface of the take-up cylinder 1 has no protruding structure, making it more aesthetically pleasing. More importantly, the winding of the wire during the take-up process is relatively uniform, and there will be no unevenness.

[0025] An automatic yarn take-up method, such as Figure 3 The process, as shown, includes the following steps:

[0026] Step S1: Threading the wire, the wire feeding tube 4 feeds the cutting wire 5 wire head into the cutting wire inlet 6 and into the cutting wire guide assembly 2, and the wire feeding tube 4 continues to feed the wire;

[0027] Step S2: Wire feeding. The wire feeding tube 4 continuously feeds the wire, and the wire head is sent out from the outlet of the cutting wire 5 through the cutting wire guide assembly 2 and crosses the main body of the cutting wire 5.

[0028] Step S3: Pressing the wire. After the wire head crosses the main body of the cutting wire 5, the wire feeding tube 4 continues to feed the wire while the take-up drum 1 rotates. The take-up drum 1 gradually accelerates, or the wire feeding tube 4 gradually decelerates, until the main body of the cutting wire 5 presses the wire head tightly, and the wire feeding speed of the take-up drum 1 and the wire feeding tube 4 are synchronized.

[0029] Step S4: Take in the yarn. The take-in drum 1 continues to rotate until the work is completed.

[0030] The foregoing has only described certain exemplary embodiments of this utility model by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of this utility model.
