[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0034] See also Figures 1 to 5 As shown, this embodiment provides a drawing die arc-shaped support positioning tool, including:

[0035] substrate1;

[0036] An arc-shaped positioning plate 2, the arc-shaped positioning plate 2 is fixedly connected to the base plate 1, and a receiving groove 21 is provided on one side wall of the arc-shaped positioning plate 2;

[0037] The supporting plate 3 is rotatably disposed in the accommodating groove 21, and a counterweight block 4 is disposed at the end of the supporting plate 3 away from the sheet side, and the counterweight block 4 is located at the side of the supporting plate 3;

[0038] The buffer member 5 is formed with an inclined surface on the side of the arc-shaped positioning plate 2 away from the sheet material, and the buffer member 5 is arranged on the inclined surface and faces the counterweight block 4;

[0039] The baffle plate 6 is arranged on the side wall of the arc-shaped positioning plate 2 to prevent the supporting plate 3 from falling into the stamping station.

[0040] Specifically, in this embodiment, the tooling is installed on the die base 7, and the arc-shaped positioning plate 2 and the supporting plate 3 are used in cooperation to meet the positioning of the complex parts and the process positioning, and the positioning is stable and reliable. At the same time, the supporting plate 3 and the counterweight block 4 are used to meet the actual supporting and counterweighting requirements, and the buffer member 5 provided on the arc-shaped positioning plate 2 can effectively buffer the falling counterweight block 4 and reduce the noise interference generated.

[0041] The arc-shaped support positioning tool for a drawing die described in this embodiment can realize the positioning of drawing dies for various complex parts. It can not only locate the placement state of the sheet material, but also control the boundary of the sheet material falling process. The positioning is stable and reliable, avoiding the uncontrollable situation that the sheet material cannot be positioned due to the complex shape of the product and the unstable placement of the sheet material. The tool can flexibly adjust the weight of the counterweight block 4 according to the weight of the support to ensure the stable positioning of the parts. At the same time, the buffer part 5 is set to effectively reduce the noise generated by the falling of the counterweight block 4.

[0042] In some embodiments, Figures 1 to 3 The portion of the support plate 3 protruding from the arc-shaped positioning plate 2 forms a support portion;

[0043] The supporting plate 3 is arranged in the receiving groove 21 by means of pins, and the top end surface of the supporting plate 3 is in contact with the top inner wall surface of the receiving groove 21 .

[0044] Specifically, in this embodiment, the portion of the supporting plate 3 that protrudes from the arc-shaped positioning plate 2 forms a supporting portion, which can support the sheet material (material sheet). By opening a receiving groove 21 on one side wall of the arc-shaped positioning plate 2, the supporting plate 3 is set in the receiving groove 21 through pins, and the supporting plate 3 can rotate around the pins. During the rotation process, the top inner wall of the receiving groove 21 can effectively block the rotation angle of the supporting plate 3.

[0045] In some embodiments, Figure 1 and Figure 2 As shown, the counterweight 4 is a circular structure;

[0046] The number of the counterweight block 4 is at least one. In response to the number of the counterweight blocks 4 being multiple, the multiple counterweight blocks 4 are stacked side by side on the supporting plate 3 through locking screws.

[0047] Specifically, in this embodiment, by arranging a plurality of circular counterweight blocks 4 on the rear side of the support plate 3, the counterweight weight can be adjusted by increasing or decreasing the number of counterweight blocks 4 to support the material, thereby avoiding deformation of the arc positioning plate 2 due to waste material caused by excessive counterweight, and inability to support the material stably due to too small counterweight. By cooperating with the buffer member 5 and the arc positioning surface of the arc positioning plate 2, stable positioning of the sheet material can be achieved.

[0048] It should be noted that, taking into account the limited space for positioning the sheet metal on site, the present embodiment sets the counterweight 4 on the side wall of the support plate 3, making full use of the side space of the tooling and not being restricted by the on-site space; at the same time, without changing the force arm of the support plate 3, the present embodiment places the same number of counterweights 4 as other tooling, which can provide greater lifting force and make the support more stable and reliable.

[0049] In some embodiments, Figure 1 and Figure 3 As shown, the two ends of the baffle plate 6 are fixedly connected to the arc-shaped positioning plate 2 by fixing screws, and the baffle plate 6 is arranged corresponding to the accommodating groove 21 .

[0050] Specifically, in this embodiment, in order to prevent the rotating pin from breaking during the supporting process, causing the supporting plate 3 to fall into the stamping station on the sheet side and causing unnecessary trouble to the processing of the sheet, this embodiment provides a baffle 6 on the side wall of the arc-shaped positioning plate 2, which can effectively prevent the supporting plate 3 from falling into the stamping station.

[0051] In some embodiments, Figures 1 to 3 As shown, the side wall of the arc-shaped positioning plate 2 close to the sheet side protrudes outward to form an arc-shaped portion 22. The arc-shaped portion 22 can position the placement state of the sheet and control the boundary of the sheet falling process. The positioning is stable and reliable, avoiding the occurrence of uncontrollable situations due to the complex shape of the product and the instability of the sheet placement and the inability to position.

[0052] The bottom end of the arc-shaped positioning plate 2 and a side wall away from the sheet material side extend outward to form a protrusion 23, and the top end surface of the protrusion 23 forms an inclined surface inclined upward;

[0053] A mounting hole is provided on the inclined surface of the raised portion 23;

[0054] The buffer member 5 comprises a buffer portion and a buffer screw connected to the buffer member 5 . The buffer screw is arranged in the mounting hole through a nut arranged thereon. The buffer portion is a polyurethane block arranged in a conical structure.

[0055] Specifically, in this embodiment, a protrusion 23 is formed by extending outward from the bottom end of the arc-shaped positioning plate 2 and a side wall away from the sheet side, and the top end face of the protrusion 23 forms an upwardly inclined inclined surface, and the buffer part 5 is arranged on the inclined surface. The buffer part adopts a conical polyurethane block, which is matched with a circular counterweight block 4. Compared with the buffer structure with plane contact, the buffer effect is better and the noise generated is greatly reduced.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
