Description

Technical Field

[0001] This application relates to the field of multi-wire cutting machine technology, and in particular to a novel wire arrangement mechanism for a multi-wire cutting machine. 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. Wire EDM technology and wire EDM machine tools are being widely used in various industries. When using an in-line cutting machine, a wire winding mechanism is required. However, ordinary wire winding mechanisms result in uneven winding of the cutting wire during take-up, and the wire winding and unwinding can easily cause the cutting wire to deviate. Therefore, we have proposed a new type of wire winding mechanism for multi-wire cutting machines. Utility Model Content

[0003] This application provides a novel wire routing mechanism for a multi-wire cutting machine to solve the problems mentioned above.

[0004] This application provides a novel wire-laying mechanism for a multi-wire cutting machine, comprising: A connecting plate, wherein the upper left side of the front end of the connecting plate is rotatably connected to a connecting pipe via a rotating shaft, and a first limiting wheel is fixedly sleeved on the outer side of the connecting pipe at equal intervals, and a plurality of second limiting wheels are rotatably connected to the middle front end of the connecting plate via a connecting rotating shaft; The wire feeding roller is rotatably disposed below the second limiting wheel, and the middle part of the wire feeding roller is rotatably connected to the inside of the limiting frame through a connecting shaft. The limiting frame is disposed on the front side of the connecting plate and can be moved back and forth. The limiter has a rectangular upper part with a rotatable limit shaft, and the outer side of the limiter is fixedly connected to the front end of the connecting plate through a first connecting rod.

[0005] Preferably, a drive motor is fixedly connected to the front end of the shaft of the wire guide roller, and the drive motor is fixedly connected to the outer front end of the limiting frame.

[0006] Preferably, a second connecting rod is fixedly connected to both sides of the limiting frame, and a limiting slide rod is fixedly connected to the rear end of the second connecting rod. The limiting slide rod is movably inserted into the connecting plate.

[0007] Preferably, stabilizing slide bars are fixedly connected to both sides of the rear end of the limiting frame.

[0008] Preferably, a connecting plate is fixedly connected to the rear end of the limiting slide rod, and an electric telescopic rod is fixedly connected to the middle of the front end of the connecting plate, with the electric telescopic rod fixedly connected to the rear end of the connecting plate.

[0009] Preferably, the first limiting wheel and the second limiting wheel have cutting lines overlapping on their upper sides, and the cutting lines are wound around the outer side of the corresponding wire feeding rollers.

[0010] The technical solutions provided in this application have the following advantages compared with the prior art: The structure provided in this embodiment uses an electric telescopic rod to move the connecting plate back and forth, which in turn moves the limiting slide rod back and forth, thereby moving the limiting frame back and forth. This allows the wire feeding roller to move back and forth, making the wire feeding or retraction more stable. Simultaneously, during wire retraction, the wire is retracted more evenly. Furthermore, the limiter and the first limiting wheel ensure stable wire movement, preventing the wire from detaching from the second limiting wheel. Meanwhile, the upper end of the first limiting wheel is slightly higher than the upper end of the second limiting wheel, thereby reducing the contact area between the cutting line and the second limiting wheel and reducing friction.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Various embodiments of this application may exist in the form of a range. It should be understood that the description in the form of a range is merely for convenience and brevity and should not be construed as a rigid limitation on the scope of this application. Therefore, it should be considered that the range description has specifically disclosed all possible sub-ranges and single numerical values ​​within that range. For example, it should be considered that the range description from 1 to 6 has specifically disclosed sub-ranges, such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and single numbers within the range, such as 1, 2, 3, 4, 5, and 6, regardless of the range. In addition, whenever a numerical range is indicated in this application, it means including any referenced number (fraction or integer) within the indicated range. Unless otherwise specified, all raw materials, reagents, instruments, and equipment used in this application can be purchased commercially or prepared using existing equipment.

[0017] In this application, unless otherwise stated, directional terms such as "upper" and "lower" specifically refer to the drawing directions in the accompanying drawings. Furthermore, in this application, the terms "comprising," "including," etc., mean "including but not limited to." In this application, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In this application, "and / or" describes the relationship between related objects, indicating that three relationships may exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. A and B can be singular or plural. In this application, "at least one" means one or more, and "more than one" means two or more. "At least one," "at least one of the following," or similar expressions refer to any combination of these items, including any combination of a single item or a plural item. For example, "at least one of a, b, or c" or "at least one of a, b, and c" can both mean: a, b, c, ab (i.e., a and b), ac, bc, or abc, where a, b, and c can be a single or multiple.

[0018] like Figures 1-3As shown in the figure, this application provides a novel wire-laying mechanism for a multi-wire cutting machine, comprising: A connecting plate 1, with an overlapping pipe 3 rotatably connected to the upper left side of the front end of the connecting plate 1 via a rotating shaft 2, and first limiting wheels 4 fixedly sleeved at equal intervals on the outer side of the overlapping pipe 3, and multiple second limiting wheels 5 rotatably connected to the middle front end of the connecting plate 1 via a connecting rotating shaft. The wire guide roller 9 is rotatably disposed below the second limiting wheel 5, and the middle part of the wire guide roller 9 is rotatably connected to the inside of the limiting frame 6 through a connecting shaft. The limiting frame 6 is disposed on the front side of the connecting plate 1 and can be moved back and forth. The limiter 15 has a rectangular upper part with a rotatable limit shaft 16, and the outer side of the limiter 15 is fixedly connected to the front end of the connecting plate 1 by a first connecting rod 14.

[0019] like Figure 1 As shown: The front end of the rotating shaft of the wire roller 9 is fixedly connected to a drive motor 10, and the drive motor 10 is fixedly connected to the outer front end of the limiting frame 6.

[0020] Specifically: the drive motor 10 adopts an existing motor on the market, which is all existing technology. The drive motor 10 can drive the wire roller 9 to rotate.

[0021] like Figure 1 As shown: The two sides of the limiting frame 6 are fixedly connected to the second connecting rod 7, and the rear end of the second connecting rod 7 is fixedly connected to the limiting slide rod 8, which is movably inserted into the connecting plate 1.

[0022] Specifically, the limiting slide bar 8 can also stabilize the forward and backward displacement of the limiting frame 6.

[0023] like Figure 3 As shown: Stable sliding rods 12 are fixedly connected to both sides of the rear end of the limiting frame 6.

[0024] Specifically: the stabilizing slide bar 12 can stabilize the forward and backward displacement of the limiting frame 6.

[0025] like Figure 3 As shown: The rear end of the limiting slide bar 8 is fixedly connected to a connecting plate 13, and the front middle of the connecting plate 13 is fixedly connected to an electric telescopic rod 11, which is fixedly connected to the rear end of the connecting plate 1.

[0026] Specifically: The electric telescopic pole 11 adopts the telescopic poles that are already available on the market, which is the existing technology. The electric telescopic pole 11 drives the limiting frame 6 to move back and forth through the limiting slide bar 8.

[0027] like Figure 1 As shown: the first limiting wheel 4 and the second limiting wheel 5 have cutting lines attached to their upper sides, and the cutting lines are wrapped around the outside of the corresponding wire feeding roller 9.

[0028] Principle: When the equipment is in use, the connecting plate 1 is fixedly connected to the set position by bolts, and the cutting wire on the corresponding wire feeding roller 9 is pulled out and inserted into the inside of the limiter 15. Then the cutting wire is overlapped on the upper side of the second limit wheel 5 and the first limit wheel 4, and then the cutting wire is arranged on the wire feeding shaft. When the cutting wire is connected, the drive motor 10 is reversed or forward rotated to drive the wire feeding roller 9 to reverse or forward rotate, thereby enabling the wire to be fed or wound. Simultaneously, the electric telescopic rod 11 is activated, causing the connecting plate 13 to move back and forth, which in turn causes the limiting slide rod 8 to move back and forth, which in turn causes the limiting frame 6 to move back and forth. This allows the wire feeding roller 9 to move back and forth, making the wire feeding or retraction more stable. Simultaneously, when the wire feeding roller 9 retracts the wire, it ensures more even wire retraction. Furthermore, under the action of the limiter 15 and the first limiting wheel 4, the running position of the cutting wire is stabilized, preventing the cutting wire from detaching from the second limiting wheel 5. Meanwhile, the upper end of the first limiting wheel 4 is slightly higher than the upper end of the second limiting wheel 5, thereby reducing the contact area between the cutting line and the second limiting wheel 5 and reducing friction.

[0029] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed in this application.
