[0041] Referring to Figures 1 to 3 , the square metal substrate 20 is a cuboid plate structure, and the square metal substrate 20 has two substantially parallel maximum end faces and four smaller side faces. The two larger end faces of the square metal substrate 20 can be temporarily defined as the first face and the second face, wherein the second face and the four side faces can be kept vertical, and the first face and the second face cannot be kept parallel because they are SLM printed, so that the first side of the square metal substrate 20 needs to be line cut, so that the first face and the second face after processing are parallel.

[0042] The embodiment provides a line cutting tool for a metal substrate, which comprises a base 10, a positioning block 30 and a pressing assembly 40.

[0043] The base 10 is used to be connected with a line cutting machine tool. The base 10 is a cuboid structure. The line cutting electrode wire is located on the side of the base 10 and arranged vertically. The upper end face of the base 10 is used to support the square metal substrate 20 (supporting the side face of the square metal substrate 20). The positioning block 30 is connected with the upper end face of the base 10, and the side face of the positioning block 30 is a positioning face 31 (a plane) which can be attached to the end face (the second face of the square metal substrate 20) of the square metal substrate 20. The pressing assembly 40 is used to press the square metal substrate 20 against the base 10. At this time, the line cutting electrode wire can move from one end to the other end of the square metal substrate 20, so as to cut the square metal substrate 20, and the first face and the second face after cutting are parallel.

[0044] In the embodiment, the square metal substrate 20 is placed on the base 10, the square metal substrate 20 is positioned by the positioning block 30, and the square metal substrate 20 is fixed by pressing against the pressing assembly 40, so that square metal substrates 20 of different sizes can be adapted. Compared with the clamping and leveling operation when the traditional wire cutting machine tool fixes the square metal substrate 20, time and labor are saved, and convenience is improved.

[0045] In one embodiment, the pressing assembly 40 includes a support frame 41, a pressing piece 42, a screw rod 43, and an adjusting nut 44.

[0046] The support frame 41 is connected with the base 10. The pressing piece 42 is vertically slidingly arranged on the support frame 41, and the lower end thereof is used to press against the upper end surface of the square metal substrate 20. The lower end of the screw rod 43 is connected with the base 10. The number of the adjusting nuts 44 corresponds to the number of the screw rods 43 (i.e., one-to-one correspondence), the adjusting nuts 44 are rotationally sleeved outside the screw rods 43, and the lower end of the adjusting nut 44 abuts against the upper end of the pressing piece 42.

[0047] In the embodiment, the pressing piece 42 vertically slides on the support frame 41 to adapt to square metal substrates 20 of different sizes, and then the adjusting nut 44 is rotated on the screw rod 43 to press the pressing piece 42 against the square metal substrate 20 to complete the fixing, and the convenience is improved.

[0048] In one embodiment, the support frame 41 includes two vertically arranged support columns 411. The lower ends of the two support columns 411 are connected with the base 10, and the two support columns 411 are located at the two ends of the positioning block 30. The two ends of the pressing piece 42 are vertically slidingly fitted with the corresponding support columns 411. The two ends of the pressing piece 42 are provided with dovetail grooves, and the side surfaces of the support columns 411 are provided with vertically arranged dovetail blocks. The dovetail blocks and the corresponding dovetail grooves are slidingly fitted, so that the pressing piece 42 can vertically slide. The arrangement of the two support columns 411 makes the pressing piece 42 more smooth and stable when vertically sliding, and the design is more reasonable.

[0049] In one embodiment, the two ends of the pressing piece 42 are respectively provided with first holes 421 which penetrate vertically; the screw rod 43 is provided with two; the upper ends of the two screw rods 43 respectively pass through the two first holes 421. The two screw rods 43 are respectively located on the inner sides of the two support columns 411. By arranging the two screw rods 43, the adjusting nuts 44 on the two screw rods 43 can apply force to the pressing piece 42 from the two ends of the pressing piece 42, the force is uniform, and the stable fixing of the square metal substrate 20 is realized.

[0050] In one embodiment, the pressing piece 42 includes a pressing portion 422 and a connecting portion 423.

[0051] The pressing part 422 is used for pressing against the square metal substrate 20. The connecting part 423 is provided with two, and the two connecting parts 423 are connected with two ends of the pressing part 422 respectively, and the connecting part 423 is in sliding fit with the corresponding supporting column 411.

[0052] The first hole 421 is arranged on the connecting part 423; the projection of the positioning block 30 and the two supporting columns 411 on the base 10 is connected to form a projection zone; the projection of the connecting part 423 on the base 10 is located in the projection zone; and the projection of the pressing part 422 on the base 10 is located outside the projection zone.

[0053] In the embodiment, the pressing part 422 presses against the upper end of the square metal substrate 20, and when the transverse dimension of the square metal substrate 20 increases, the square metal substrate 20 will not interfere with the supporting column 411 because the pressing part 422 is located outside the projection zone, which makes the tooling suitable for more sizes of the square metal substrate 20.

[0054] In one embodiment, two second holes are arranged on the base 10. The supporting column 411 comprises a stabilizing block 412 extending transversely at the lower end thereof. The stabilizing block 412 is provided with a third hole 413, and the second hole and the third hole 413 are connected by a bolt. The stabilizing block 412 abuts against the base 10.

[0055] In the embodiment, the bottom of the supporting column 411 extends transversely to form the stabilizing block 412, which can increase the contact area with the base 10, so that the supporting column 411 is more stable after being connected with the base 10, and the volume of other parts of the supporting column 411 can be reduced, the material is saved, and the design is more reasonable.

However, it can be understood that the embodiments of the utility model can be practiced without these specific details. In some examples, well-known methods, structures and technologies are not shown in detail, so as not to obscure the understanding of the specification.
