Abstract
Description
Technical Field
[0001] This utility model relates to a magnet cutting fixture, and more particularly to a square magnet cutting fixture. Background Technology
[0002] Square magnets (i.e., block-shaped magnets) are a common magnet shape. In the manufacturing process, to improve production efficiency, the die-cast magnets are not necessarily the exact size required after casting. Instead, they are die-cast into blanks. After subsequent processing, these blanks (the magnets to be cut) are fixed in place using tooling and placed on the cutting table of a multi-wire cutting machine. The machine then cuts the magnets into multiple square magnets using multi-segment wire cutting. In existing technology, multiple magnets are typically bonded together with an adhesive before cutting. The problem with this method is that the adhesive needs to be removed, making the process cumbersome.
[0003] CN221833494U discloses a tooling assembly. This tooling assembly is used for arranging and positioning cutting blanks during wire cutting. The cutting blanks have opposing first and second cutting surfaces, as well as opposing third and fourth cutting surfaces. The tooling assembly includes: a first tooling, comprising: a first base plate abutting against the first cutting surface of a first cutting blank; a second base plate disposed at the end of the first base plate, the angle between the inner wall of the second base plate and the inner wall of the first base plate being an obtuse angle, and the end faces of multiple cutting blanks abutting against the second base plate; and a second tooling, disposed on the base plate of a multi-wire cutting machine, used for positioning the arranged cutting blanks on the multi-wire cutting machine. This tooling assembly is also used to form irregular magnets.
[0004] CN118237680A discloses a tooling for multi-wire cutting of magnetic tiles, including a base, two mounting strips, a first drive, and two clamping parts. Each end of the magnetic tile has two connecting lines, formed by connecting the arc-shaped surface of the magnetic tile and the horizontal surface of its end. Of the two connecting lines at one end of the magnetic tile, the lower connecting line is relatively inward and abuts against the horizontal support surface; the upper connecting line is relatively outward and abuts against the vertical abutting surface. This tooling is suitable for multi-wire cutting of magnetic tiles. Utility Model Content

Figure 3 This is a top view schematic diagram of a square magnet cutting fixture according to the present invention. Figure 4 This is a partial schematic diagram of a square magnet cutting fixture of this utility model in use.
[0060] like Figures 1 to 4 As shown, this embodiment of the square magnet cutting fixture is suitable for cutting square magnets. That is, the magnet 10 to be cut is a square magnet. The square magnet cutting fixture of this utility model includes a base 100 and one or more cutting fixture units 200. There are two or more cutting fixture units 200; the two or more cutting fixture units 200 are spaced apart. Specifically, as shown... Figure 1 and Figure 3 As shown, there are 3 cutting fixture units 200.
[0061] In this embodiment, the cutting fixture unit 200 includes a first side baffle 210, a second side baffle 220, a positioning pin 230, a fixing plate 240 and a pad (not shown), and also includes an end plate (not shown).
[0062] The first side baffle 210 and the second side baffle 220 are both located on the base 100 and perpendicular to the base 100. The first side baffle 210 and the second side baffle 220 are arranged parallel to each other. Both the first side baffle 210 and the second side baffle 220 are provided with multiple sets of cutting modules and multiple interval channels 252. Each side baffle has 3 or more sets of cutting modules, for example, 5 or more sets. Specifically, each side baffle has 8 sets of cutting modules. Each set of cutting modules includes multiple cutting channels 251. Specifically, each set of cutting modules is provided with 3 cutting channels 251, and these 3 cutting channels 251 are evenly spaced.
[0063] A set of cutting modules is provided between two adjacent spaced channels 252 on each side baffle. The cutting modules of the first side baffle 210 and the second side baffle 220 correspond to each other. The spaced channels 252 of the first side baffle 210 and the second side baffle 220 correspond to each other.
[0064] Multiple magnets 10 to be cut can be clamped between the first side baffle 210 and the second side baffle 220. The magnets 10 to be cut are located between the cutting modules of the first side baffle 210 and the second side baffle 220. That is, a set of magnets 10 to be cut is clamped between a set of cutting modules of the first side baffle 210 and a corresponding set of cutting modules of the second side baffle 220. Depending on the actual size of the magnets 10 to be cut, a set of magnets 10 can consist of one piece or four pieces. In this embodiment, a set of magnets 10 consists of four pieces. Specifically, as shown... Figure 1 and Figure 4 As shown, four magnets 10 to be cut are sandwiched between a set of cutting modules of the first side baffle 210 and a corresponding set of cutting modules of the second side baffle; two magnets 10 to be cut are located below, and the other two magnets 10 to be cut are stacked on top; in use, the plane of the upper surface of the first side baffle 210 and the upper surface of the second side baffle 220 is lower than the plane of the upper surface of the magnets 10 to be cut located above.
[0065] like Figure 4 As shown, there are multiple positioning pins 230. One end of some positioning pins 230 can pass through the spacer channel 252 of the first side baffle 210 and be embedded between adjacent magnets 10 to be cut along the length direction of the first side baffle 210; one end of other positioning pins 230 can pass through the spacer channel 252 of the second side baffle 220 and be embedded between adjacent magnets 10 to be cut along the length direction of the second side baffle 220; and some positioning pins 230 are vertically embedded between adjacent magnets 10 to be cut along the length direction of the first side baffle 210. The positioning pins 230 are used to assist in positioning the magnets 10 to be cut.
[0066] Specifically, such as Figure 4As shown, the positioning pin 230 includes a pin portion 232 and a pressure plate portion 231 that are vertically connected. The pin portion 232 has an elongated structure, and the pressure plate portion 231 has a square sheet structure. The surface area of the pressure plate portion 231 near the pin portion 232 is larger than the cross-sectional area of the pin portion 232. In use, a portion of the pin portion 232 is embedded between adjacent magnets 10 to be cut along the length direction of the first side baffle 210.
[0067] like Figure 1 As shown, the fixing plate 240 is horizontally mounted on the base 100. Specifically, the fixing plate 240 is connected to the base 100 by bolts. The first side baffle 210 is connected to one side of the fixing plate 240, and the two form an L-shaped cross-section. In this embodiment, the first side baffle 210 and the fixing plate 240 can be integrally formed into an L-shaped cross-section.
[0068] The second side baffle 220 is connected to the side of the fixing plate 240 away from the first side baffle 210 by multiple positioning bolts 301. The positioning bolts 301 are countersunk bolts.
[0069] In use, the pad is positioned above the fixing plate 240 and below the magnet 10 to be cut. The pad can be a stone slab.
[0070] The end plate is mounted on the fixed plate 240 and fits against the end face of the first side baffle 210 and the end face of the second side baffle 220. The end plate is used to limit the movement of the magnet 10 to be cut.
[0071] The assembly and usage method of the square magnet cutting fixture in this embodiment are described below:
[0072] Place the base 100 horizontally on the table. Place the L-shaped structure formed by the first side baffle 210 and the fixing plate 240 on the base 100. Fix the fixing plate 240 to the base 100 with bolts. Then, vertically fix the end plate to the fixing plate 240, close to one end face of the first side baffle 210. Place the first side baffle 210 of the three cutting fixture units 200 perpendicular to the base 100 in this manner. Place the pad on the fixing plate 240. Then, place four magnets 10 to be cut close to the first side baffle 210 and the end plate, with two magnets 10 at the bottom and the other two stacked on top. Figure 2As shown, the cutting modules near the end plate are defined as the first group. Then, along the length of the first side baffle 210, they are sequentially designated as the second, third, fourth, fifth, sixth, seventh, and eighth groups, meaning one cutting fixture unit can hold a total of 32 magnets 10 to be cut. The second side baffle 220 is connected to the side of the fixing plate 240 away from the first side baffle 210 using positioning bolts 301. Before tightening the second side baffle 220, positioning pins 230 are inserted between adjacent magnets 10 to be cut along the length of the first side baffle 210 and the second side baffle 220. Some positioning pins 230 have one end horizontally passing through the spacing channel 252, while others are vertically inserted between adjacent magnets 10 to be cut along the length of the first side baffle 210 or the second side baffle 220. The pressure plate 231 is located outside the first side baffle 210 and the second side baffle 220. Then, tighten the positioning bolt 301 to position the magnet 10 to be cut between the first side baffle 210 and the second side baffle 220. Fix the base 100 of the square magnet cutting fixture, with the magnet 10 positioned there, onto the corresponding platform of the cutting machine, and remove the positioning pin 230. Then, use the cutting machine to cut the magnet 10. One cutting fixture unit 200 can cut 128 small (8×4×4) square magnets.
[0073] Example 2
[0074] The only difference from Embodiment 1 is that the square magnet cutting fixture in this embodiment also includes an auxiliary side plate (not shown).
[0075] When the size of the magnet to be cut is small, an auxiliary side plate is used between the second side baffle 220 and the magnet 10 to be cut to limit the magnet 10. In use, the auxiliary side plate is perpendicular to the base 100, and both sides of the auxiliary side plate are in close contact with the magnet 10 to be cut and the second side baffle 220, respectively. The auxiliary side plate is also provided with multiple sets of cutting modules and multiple spacing channels 252. The cutting modules and spacing channels 252 of the auxiliary side plate correspond to the cutting modules and spacing channels 252 of the second side baffle 220 or the first side baffle 210.
