[0031] Please refer to Figures 1 to 4 .

[0032] The embodiment provides a sample making tool which can be quickly assembled, has simple structure, is simple to manufacture, easy to realize and low in cost, solves the problems of too complex structure and large assembly design cost of the existing tool structure for positioning sheet metal parts, and mainly used for sheet metal part discharge positioning, comprising a steel plate group 1 and an assembly structure, wherein,

[0033] The steel plate group 1 mainly comprises horizontal steel plates 11 and vertical steel plates 12; the horizontal steel plates 11 and the vertical steel plates 12 are both vertically arranged, each horizontal steel plate 11 is arranged in parallel along a longitudinal gap (the longitudinal direction refers to the plate length direction of the vertical steel plate 12), each vertical steel plate 12 is arranged in parallel along a transverse gap (the transverse direction refers to the plate length direction of the horizontal steel plate 11), and each horizontal steel plate 11 and vertical steel plate 12 is perpendicular to the horizontal plane, wherein the top profile of the horizontal steel plate 11 and the vertical steel plate 12 is matched with part of the outer profile of the sheet metal part;

[0034] In the embodiment, please refer to Figure 5For example, to manufacture the horizontal steel plate 11: first, the three-dimensional model of the sheet metal part is cut horizontally on the three-dimensional software (three sections), and then the curved contour path of the sheet metal part on the three sections is collected, and then the shape contour of the horizontal steel plate 11 is designed and drawn according to the three contour paths, and then the shape contour is transmitted to the laser cutting machine to cut out three horizontal steel plates 11, and the top contour of the three horizontal steel plates 11 can be adapted to the three local curved surfaces of the sheet metal part. When the sheet metal part is placed on the three horizontal steel plates 11, the top contour of the three horizontal steel plates 11 can support and support the sheet metal part, and the top contour is tightly connected between the three local curved surfaces of the sheet metal part; similarly, the longitudinal steel plate 12 is cut longitudinally to finally manufacture the longitudinal steel plate 12; the larger the volume of the part, the more steel plates are required, such as the sheet metal part in this embodiment, which uses seven horizontal steel plates 11 and longitudinal steel plates 12, and the seven horizontal steel plates 11 and longitudinal steel plates 12 are longitudinally and horizontally interlaced to fit and assemble to support and position the entire sheet metal part, so that the sheet metal part does not tilt or shift.

[0035] In this embodiment, in order to splice and assemble the horizontal steel plate 11 and the longitudinal steel plate 12, a splicing structure is designed; see Figure 2 and Figure 3 The splicing structure mainly includes a plurality of upper slots 21 formed on the horizontal steel plate 11 and a plurality of lower slots 22 formed on the longitudinal steel plate 12, the upper slots 21 are extended from the top of the horizontal steel plate 11 in a direction perpendicular to the horizontal plane, and the lower slots 22 are extended from the bottom of the longitudinal steel plate 12 in a direction perpendicular to the horizontal plane. The position of the upper slot 21 and the lower slot 22 is mainly the position of the three-dimensional model of the sheet metal part when it is cut horizontally and longitudinally, that is, when the shape contour of the horizontal steel plate 11 and the longitudinal steel plate 12 is drawn, the upper slot 21 and the lower slot 22 will be drawn according to the position of the cut view. When the laser cutting machine manufactures the horizontal steel plate 11 and the longitudinal steel plate 12, the position of the upper slot 21 and the lower slot 22 can be determined, and the shape can be integrally formed without additional slotting process.

[0036] In this embodiment, see Figure 3 , a structure schematic diagram before the one horizontal steel plate 11 and the one longitudinal steel plate 12 are connected and installed; see Figure 1 , a structure schematic diagram after each horizontal steel plate 11 and longitudinal steel plate 12 group 1 is assembled and spliced, each upper slot 21 and each corresponding lower slot 22 are connected and installed to make each horizontal steel plate 11 and at least two longitudinal steel plates 12 correspondingly vertically connected, that is, one horizontal steel plate 11 is vertically connected with at least two longitudinal steel plates 12, and vice versa, one longitudinal steel plate 12 is vertically connected with at least two horizontal steel plates 11, so that a better supporting effect can be formed to exert a supporting force on the sheet metal part, and the overall sheet metal part is more stable in position.

[0037] In the embodiment, the upper slot 21 has a slot depth less than the height of the horizontal steel plate 11, and the lower slot 22 has a slot depth less than the height of the vertical steel plate 12, that is, the upper slot 21 and the lower slot 22 are only formed on the steel plate for a certain distance without being directly penetrated; wherein the number of the upper slot 21 and the lower slot 22 on the horizontal steel plate 11 and the vertical steel plate 12 is equal, and the slot depth of each corresponding upper slot 21 and lower slot 22 is equal.

[0038] In the embodiment, the upper slot 21 is arranged on the horizontal steel plate 11 at a certain interval, and the interval is used to adjust the distance between the vertical steel plates 12; the lower slot 22 is arranged on the vertical steel plate 12 at a certain interval, and the interval is used to adjust the distance between the horizontal steel plates 11; in the structure, the reasonable distance between the steel plates is beneficial to better support the sheet metal parts, and can also reduce the number of steel plates and save the manufacturing cost.

[0039] In the embodiment, the horizontal steel plate 11 and the vertical steel plate 12 are provided with the identification part 3, and the identification part 3 is protruding or recessed; the identification part 3 is Y1, Y2, Y3, etc. arranged on the horizontal steel plate 11 and X1, X2, X3, etc. arranged on the vertical steel plate 12, so that the horizontal steel plate 11 and the vertical steel plate 12 can be quickly assembled when spliced, the installation efficiency is improved, and the mixed assembly due to more plates is prevented; the identification part 3 is drawn at the same time when the contour of the horizontal steel plate 11 and the vertical steel plate 12 is drawn, so that the horizontal steel plate 11 and the vertical steel plate 12 with the identification part 3 can be integrally formed by using a laser cutting machine.

[0040] In the embodiment, the identification part 3 is located at both sides of the horizontal steel plate 11 and the vertical steel plate 12, and the identification part 3 avoids the vertical connection line formed by the horizontal steel plate 11 and the vertical steel plate 12, so that the laser cutting manufacturing process is not easy to make mistakes, and the identification part 3 will not be damaged.
