Description

Technical Field

[0001] The utility model relates to the technical field of permanent magnet production, in particular to a permanent magnet wire cutting device. Background Art

[0002] Permanent magnets, as the name implies, are objects that can maintain their own magnetism for a long time without an external magnetic field. Depending on the material, they can generally maintain their magnetism for 10 years. Permanent magnets can be made of ferromagnetic materials such as iron and nickel. Wire EDM is referred to as wire cutting. It is developed on the basis of EDM perforation and forming processing. It not only develops the application of EDM, but also replaces EDM perforation and forming processing in some aspects. Wire cutting machine tools have accounted for most of EDM machine tools.

[0003] In the production process of permanent magnets, it is necessary to use wire cutting to divide the permanent magnets into several magnetic blocks of different sizes, so as to facilitate subsequent production. The existing permanent magnet wire cutting device requires manual hand-holding of the permanent magnet blocks to cut the permanent magnets during the cutting process, so as to cut the permanent magnets into different shapes, which is easy to cause danger during processing. In addition, during the cutting process of the permanent magnets, the sparks and waste chips generated will also fly randomly, which will further cause the danger of cutting. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] For example, see Figures 1 to 4 The utility model provides a technical solution: a permanent magnet wire cutting device, including an operating table 1, a cutting shell 2 and a collecting shell 3 are respectively installed on the upper and lower surfaces of the center of the operating table 1, a motor 4 is fixedly installed on one side surface of the cutting shell 2, the output shaft of the motor 4 penetrates into the cutting shell 2 and is limitedly rotated and connected with a threaded rod 5, the external thread of the threaded rod 5 is sleeved with a displacement frame 6, a slide groove 7 is opened on the upper surface of the operating table 1, a slide rod 8 is slidably connected in the slide groove 7, and the slide rod 8 is fixedly connected to the lower surface of the displacement frame 6, and a clamping plate 12 for stabilizing the permanent magnet is slidably connected at the four corners of the displacement frame 6, a group of vacuum cleaners 14 obliquely upward are symmetrically installed on both sides of the upper surface of the operating table 1, and the vacuum cleaners 14 are installed in the cutting shell 2, and the other end of the vacuum cleaners 14 penetrates into the collection shell 3 and is fixedly connected with a dust suction pipe 15, a collection drawer 31 is slidably provided in the collection shell 3, and a handle 32 is fixedly connected to the outer surface of the collection drawer 31;

[0022] A hydraulic cylinder 16 is fixedly installed on the upper surface of one side of the operating table 1, and a vertical bracket 17 is fixedly connected to the output end of the hydraulic cylinder 16. A wire rack 18 is horizontally connected to the top of the vertical bracket 17, and a cutting wire 19 for cutting permanent magnets is connected to the wire rack 18. A connecting frame 20 and a transparent dustproof shell 21 are fixedly connected to the side of the vertical bracket 17 close to the cutting shell 2, and the lower surface of the transparent dustproof shell 21 is sealed and laid on the upper surface of the cutting shell 2, and a cutting notch 22 is opened on the upper surface of the transparent dustproof shell 21 for the cutting wire 19 to pass through.

[0023] More specifically, in the present embodiment, when the operator needs to place or remove the permanent magnet, the hydraulic cylinder 16 can be started, and the output end of the hydraulic cylinder 16 drives the vertical bracket 17 to move upward or downward accordingly, and the vertical bracket 17 also synchronously drives the wire rack 18 and the transparent dustproof shell 21 to move accordingly, until the transparent dustproof shell 21 sealing cover is set on the cutting shell 2, so as to achieve the purpose of convenient observation and protection during the cutting process, or the transparent dustproof shell 21 and the wire rack 18 are away from the cutting shell 2, and the wire rack 18 drives the cutting wire 19 away from the displacement rack 6, so as to facilitate the operator to safely place the permanent magnet on the displacement rack 6, thereby ensuring the safety protection effect of the cutting device during cutting and placing the permanent magnet. When the operator places the permanent magnet on the displacement rack 6, After being clamped firmly by the clamping plate 12, the motor 4 and the vacuum cleaner 14 can be started. The output shaft of the motor 4 will also drive the threaded rod 5 to perform limited thread rotation. As the threaded rod 5 rotates, the displacement frame 6 also drives the slide rod 8 to slide within the slide groove 7, and the displacement frame 6 sleeved on the outside of the threaded rod 5 will also drive the permanent magnet to enter the automated cutting trajectory and be cut by the cutting line 19, avoiding the operator's dangerous operation of cutting by hand, thereby further ensuring the safety protection effect of the cutting device during the cutting process. During this process, the vacuum cleaner 14 collects the splashed waste chips through the dust suction pipe 15 into the collection drawer 31 in the collection shell 3, and the operator can use the handle 32 to uniformly process the waste chips in the collection drawer 31.

[0024] Furthermore, sliding bevel grooves 9 are provided in the four diagonal directions of the upper surface of the displacement frame 6, and a slider 10 is slidably connected in the sliding bevel groove 9.

[0025] It is worth mentioning that when the operator places the permanent magnet on the displacement frame 6, the clamping plate 12 will be pushed according to the size of the permanent magnet. During the pushing process, the sliding block 10 slides in the sliding chute 9, driving the clamping plate 12 to change the clamping size. The spring 11 is compressed during the pushing process to provide a stable clamping pressure for the clamping plate 12. The anti-slip pad 13 can provide an anti-slip effect for the clamped permanent magnet.
