Description

Technical Field

[0001] This utility model relates to the technical field of wire EDM equipment accessories, and more specifically, to a wire stabilizing device for wire EDM equipment. Background Technology

[0002] Wire EDM equipment uses a high-speed cutting wire (such as molybdenum wire) to precisely cut workpieces. Whether it's the wire threading and unthreading before and after cutting, or the cutting process itself, the wire needs to wind around a wire spool. In existing technologies, due to the lack of effective restraint mechanisms along the wire's path into the spool, the wire is subject to tension fluctuations and mechanical vibrations, causing severe shaking and deviation in its winding trajectory on the spool, resulting in wire stacking and tangling. Furthermore, during the cutting process, the wire adheres to workpiece plating debris and metal dust, which enter other components of the wire EDM equipment, such as guide rollers and die channels, causing abnormal wear on the guide rollers and die blockage. This significantly increases equipment maintenance frequency and downtime losses, severely impacting continuous operation capability and equipment lifespan. Therefore, overcoming the shortcomings of existing technologies and developing a wire stabilizing device that combines wire stabilization, vibration suppression, and self-cleaning functions is an urgent problem to be solved in this technical field. Utility Model Content

[0003] This utility model provides a wire stabilizing device for wire EDM equipment, which aims to improve the problems of wire stacking and tangled wires caused by uneven winding due to vibration before the cutting wire enters the wire drum, as well as the problems of impurities attached to the surface of the cutting wire accelerating the wear of the guide wheel of the wire EDM equipment and clogging the eyepiece, thus affecting the stability and service life of the equipment.

[0004] To achieve the above objectives, this utility model provides a wire stabilizing device for wire EDM equipment, the specific technical solution of which is as follows:

[0005] A wire stabilizing device for wire cutting equipment includes a wire stabilizing part with a through groove through which the cutting wire passes. The through groove is provided with at least two wear-resistant blocks, and a V-shaped groove is formed between the two wear-resistant blocks. The V-shaped groove abuts against the cutting wire passing through the through groove.

[0006] In one embodiment, the wear-resistant block may be disposed at at least one of the lower side, upper side, or middle position of the through groove.

[0007] In one embodiment, the stabilizing part includes a fixing rod, one end of which is provided with a stabilizing head, the through groove is formed on the stabilizing head, the front end of the stabilizing head is provided with an installation groove, and two wear-resistant blocks are disposed in the installation groove.

[0008] In one embodiment, the fixing rod and the stabilizing head are an integral structure.

[0009] In one embodiment, a baffle is provided at the opening of the through groove, and the baffle is fixed to the wire stabilizer to prevent the cutting wire from coming out.

[0010] In one embodiment, the wear-resistant block is fixed in the mounting groove by locking bolts.

[0011] In one embodiment, the wear-resistant block is a cylinder or a triangular prism.

[0012] In one embodiment, when the wear-resistant block is a cylinder, the wear-resistant block is a structure that can rotate about its own axis.

[0013] In one embodiment, the fixing rod is provided with a locking hole, and a connecting block is locked to one side of the fixing rod through the locking hole. The fixing rod can be installed on the wire cutting equipment through the connecting block.

[0014] In one embodiment, the fixing rod is also provided with an adjustment hole, through which the distance between the stabilizing head and the cutting wire can be adjusted.

[0015] In one embodiment, the adjustment hole is an oblong hole.

[0016] In one embodiment, the working surface of the wear-resistant block is made of diamond or cubic boron nitride.

[0017] The beneficial effects of this embodiment are: by setting a wear-resistant block assembly with a V-groove structure, it can suppress wire vibration while scraping off surface impurities, achieving a synergistic effect of wire stabilization and cleaning. Specifically, this utility model has the following advantages:

[0018] 1. By setting up a wire stabilizing part, two wear-resistant blocks are installed on the wire stabilizing part. The two wear-resistant blocks form a V-shaped groove. The cutting wire running on the wire cutting equipment passes through the wire stabilizing head and abuts against the V-shaped groove. The V-shaped groove provides support for the cutting wire, greatly reducing the vibration of the wire cutting wire and effectively preventing the occurrence of wire stacking and tangling when the cutting wire is wrapped on the wire spool of the wire cutting equipment.

[0019] 2. When the cutting wire cuts the workpiece, it will adhere to the plating, dust and other impurities on the workpiece. As the cutting wire moves, the impurities will accelerate the wear of the guide rollers and other components on the wire cutting equipment. At the same time, the impurities can easily accumulate in the wire threading die and block it. By setting wear-resistant blocks, two wear-resistant blocks form a V-groove. The cutting wire running on the wire cutting equipment passes through the wire head and abuts and rubs against the V-groove. The V-groove will scrape off the impurities adhering to the cutting wire, which plays a role in cleaning the impurities on the cutting wire. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] The technical solutions provided by the embodiments of this utility model are described below with reference to the accompanying drawings.

[0040] Please see Figure 1-11 One embodiment of this utility model provides a wire stabilizing device for wire cutting equipment.

[0041] The device includes a wire stabilizing section 10, which has a transverse through groove 210 through which the cutting wire passes. The through groove 210 is provided with at least two wear-resistant blocks 400. Specifically, the wear-resistant blocks 400 can be located at least one of the lower side, upper side, or middle position of the through groove 210. A V-shaped groove is formed between the two wear-resistant blocks 400. The V-shaped groove abuts against the cutting wire passing through the through groove 210, providing support for the cutting wire and reducing the vibration of the wire cutting wire. In addition, the V-shaped groove can abut against and rub against the running cutting wire, scraping off the impurities adhering to the cutting wire, thus cleaning the impurities on the cutting wire.

[0042] Specifically, the wire stabilizing part 10 includes a fixing rod 100, one end of which is provided with a wire stabilizing head 200. A through groove 210 is formed on the wire stabilizing head 200. Preferably, the fixing rod 100 and the wire stabilizing head 200 are an integral structure. The integral structure has good strength and can be integrally formed by mold, which is convenient to produce, beautiful and durable. The front end of the wire stabilizing head 200 is provided with an installation groove 220, and two wear-resistant blocks 400 are set in the installation groove 220.

[0043] Preferably, a baffle 240 is provided at the upper opening of the through groove 210. The baffle 240 is fixed to the upper end face of the wire stabilizer head 200 by bolts. The baffle 240 blocks the opening of the through groove 210 to prevent the cutting wire from coming out from the upper opening of the through groove 210 during operation, thus playing a blocking and limiting role.

[0044] Preferably, the front end of the stabilizing head 200 is provided with two mounting slots 220. Two wear-resistant blocks 400 adapted to it are fixedly installed in the mounting slots 220 by locking bolts. The wear-resistant blocks 400 can be made of wear-resistant and corrosion-resistant metals such as diamond or cubic boron nitride. Preferably, the wear-resistant blocks 400 are cylindrical, but other shapes, such as triangular prisms, can also be used. Figure 6 As shown, when the wear-resistant block 400 is a cylinder, it is configured as a cylindrical structure that can rotate around its own axis. When the wear-resistant block 400 is severely worn after long-term operation, the cylinder can be rotated so that the unworn part of the wear-resistant block 400 comes into contact with the cutting wire. The wear-resistant block 400 with a cylindrical body has all parts of its outer cylindrical surface that can come into contact with the cutting wire through rotation adjustment, which greatly improves the utilization rate of the wear-resistant block 400 and reduces the cost of use.

[0045] Two V-shaped grooves, upper and lower, will be formed between the two wear-resistant blocks 400. The cutting wire that passes through the stabilizing head 200 and the through groove 210 can abut against the upper V-shaped groove (e.g., Figure 2 (As shown); it can also abut against the V-groove on the lower side (as shown). Figure 4 As shown, the cutting wire abuts against the V-groove, which provides support to the wire cutting wire, greatly reducing its vibration and effectively preventing it from getting tangled or overlapping on the wire spool. Furthermore, when the cutting wire cuts a workpiece, it picks up impurities such as plating, powder, and dust. These impurities travel with the wire, accelerating wear on the guide wheels and other parts of the wire cutting equipment that come into contact with the wire. Simultaneously, impurities easily accumulate in the die, clogging it and preventing proper wire threading or cutting. By setting up wear-resistant blocks 400, two blocks 400 form a V-groove. The cutting wire running on the wire cutting equipment passes through the wire stabilizer head 200 and abuts against the V-groove, scraping off the impurities attached to the wire, thus cleaning it and significantly mitigating the aforementioned problems.

[0046] It should be noted that a locking hole 110 is also provided on the fixing rod 100. A connecting block 300 is locked to one side of the fixing rod 100 through the locking hole 110. Specifically, the screw of the locking bolt passes through the locking hole 110 and is then locked into the threaded hole on the fixing rod 100, thereby achieving the locking and fixing of the fixing rod 100 and the connecting block 300. The fixing rod 100 can be installed on the wire cutting equipment through the connecting block 300, thereby realizing the installation of the wire stabilizing device on the wire cutting equipment. In addition, an adjustment hole 120 is also provided on the fixing rod 100. The adjustment hole 120 is an elongated hole. By cooperating with the adjustment hole 120, the installation angle between the fixing rod 100 and the connecting block 300 can be adjusted, thereby adjusting the distance between the wire stabilizing head 200 and the cutting wire, so that the cutting wire can abut against the wear-resistant block 400 on the wire stabilizing head 200.

[0047] The specific adjustment method is as follows: when the cutting wire is above the V-groove on the wear-resistant block 400, loosen the bolts on the locking hole 110 and the adjusting hole 120, and then gently lift the stabilizing head 200 upward. At this time, the stabilizing head 200 drives the wear-resistant block 400 on it to rotate upward around the central axis of the adjusting hole 120. The position of the cutting wire remains unchanged until the rising wear-resistant block 400 abuts against the cutting wire. Then stop the stabilizing head 200 from rotating upward and tighten the bolts on the locking hole 110 and the adjusting hole 120. The whole process is convenient to adjust and easy to use, and the mobility and flexibility of the device are greatly improved.
