[0054] This application discloses a positioning stamping die. Figure 1 This is a schematic diagram of a positioning stamping die provided in an embodiment of this application. Figure 1 ,like Figure 1 As shown, the positioning stamping die includes an upper die 1 and a lower die 2. The upper die 1 includes an upper template 11 and an elastic drive module 12. The upper template 11 includes a first cavity 111, in which the elastic drive module 12 is movably disposed. The lower die 2 includes a lower template 21, a fixed positioning block 22, and an elastic positioning module 23, with the fixed positioning block 22 and the elastic positioning module 23 located at opposite ends of the lower template 21. The lower template 21 includes a second cavity 211, in which the elastic positioning module 23 is movably disposed. The elastic positioning module 23 is located below the elastic drive module 12. The positioning stamping die is used to move the elastic drive module 12 in the first cavity 111 and the elastic positioning module 23 in the second cavity 211 when the elastic drive module 12 moves downward and contacts the elastic positioning module 23, until the elastic positioning module 23 and the fixed positioning block 22 clamp the sheet metal located on the lower template 21.
[0055] In this embodiment, the plate is clamped by the movement of the elastic positioning module 23 after contacting the elastic drive module 12, so that the mold can adapt to the size deviation of the plate and avoid poor plate forming.
[0056] Figure 2 This is a schematic diagram of a positioning stamping die provided in an embodiment of this application. Figure 2 As shown in Figure 2, during the downward movement of the upper mold 1, the elastic drive module 12 comes into contact with the elastic positioning module 23, and the gap between the elastic positioning module 23 and the plate gradually decreases. Figure 3 This is a schematic diagram of a positioning stamping die provided in an embodiment of this application. Figure 3 As shown in Figure 3, the elastic positioning module 23 and the fixed positioning block 22 clamp the plate located on the lower template 21, and the bottom surface of the upper template 11 contacts the top surface of the plate.
[0057] In an optional embodiment, if the sheet material is placed in the lower template 21 and is clamped by the elastic positioning module 23 and the fixed positioning block 22 (the left end of the sheet material contacts the fixed positioning block 22, and the right end of the sheet material contacts the elastic positioning module 23), the upper mold 1 moves downward, the elastic positioning module 23 is constrained by the sheet material and does not move in position, and the elastic drive module 12 moves to the right in the first empty space 111 until the bottom surface of the upper template 11 in the upper mold 1 contacts the sheet material.
[0058] In another optional embodiment, if the sheet material is not clamped by the elastic positioning module 23 and the fixed positioning block 22 after being placed in the lower template 21 (the left end of the sheet material contacts the fixed positioning block 22, and the right end of the sheet material has a certain gap with the elastic positioning module 23), the upper mold 1 moves downward. After the elastic drive module 12 and the elastic positioning module 23 come into contact, the elastic drive module 12 continues to move downward, and at the same time, the elastic drive module 12 and the elastic positioning module 23 will move horizontally. The elastic drive module 12 moves to the right in the first empty space 111, and the elastic positioning module 23 moves to the left in the second empty space 211, until the elastic positioning module 23 and the fixed positioning block 22 clamp the sheet material. Subsequently, the upper mold 1 continues to move downward, and the elastic drive module 12 is constrained by the sheet material and does not move. The elastic drive module 12 continues to move to the right in the first empty space 111 until the bottom surface of the upper template 11 in the upper mold 1 contacts the sheet material.
[0059] In this embodiment, to make the stamping die suitable for sheet metal with certain dimensional deviations, the structure in the lower die 2 that clamps both ends of the sheet metal is configured as a fixed positioning block 22 with a fixed position and an elastic positioning module 23 that can move within a certain range. Simultaneously, to enable the elastic positioning module 23 to cooperate with the fixed positioning block 22 to clamp the sheet metal, an elastic drive module 12 is provided in the upper die 1. The elastic drive module 12 can cooperate with the elastic positioning module 23 to promote the positional movement of the elastic positioning module 23 in the lower die 2, thereby shortening the gap between the elastic positioning module 23 and the sheet metal. Moreover, after the elastic positioning module 23 and the fixed positioning block 22 clamp the sheet metal, the elastic drive module 12, which is in contact with the elastic positioning module 23, can also prevent the elastic positioning module 23 from moving.
[0060] Figure 4 This is a schematic diagram of a positioning stamping die provided in an embodiment of this application. Figure 4 ,like Figure 4 As shown, the elastic drive module 12 includes an elastic drive block 121, a first bolt 122, and a first spring 123. The first empty space 111 includes a first empty space portion 1111, a second empty space portion 1112, and a third empty space portion 1113 connected in sequence. The width of the second empty space portion 1112 is smaller than the width of the first empty space portion 111 and the third empty space portion 1113.
[0061] In this embodiment, the elastic drive block 121 is located in the first empty portion 1111, and the elastic drive block 121 can move horizontally in the first empty portion 1111. The first bolt 122 is entirely located in the first empty portion 1111, the second empty portion 1112, and the third empty portion 1113, with the first end of the first bolt 122 located in the first empty portion 111 and the second end of the first bolt 122 located in the third empty portion 1113. The first end of the first bolt 122 is connected to the elastic drive block 121, and the first bolt 122 moves with the movement of the elastic drive block 121. The first spring 123 is sleeved on the outside of the first bolt 122, and the first spring 123 is located in the third empty portion 1113. The first spring 123 compresses and shortens or extends and lengthens as the first bolt 122 moves left and right.
[0062] In this embodiment, since the width of the second empty portion 1112 is smaller than the widths of the first empty portion 111 and the third empty portion 1113, when the first bolt 122 moves to the right with the elastic drive block 121, the first spring 123 remains in the third empty portion 1113 due to the width of the second empty portion 1112, and is further compressed as the elastic drive block 121 moves to the right. When the first bolt 122 moves to the left with the elastic drive block 121, the compression of the first spring 123 gradually decreases.
[0063] In some possible embodiments, the elastic drive block 121 is detachably connected to the first bolt 122. A cavity is provided at the bottom of the elastic drive block 121, and the first bolt 122 is inserted into the cavity to fix it to the elastic drive block 121. Because the elastic drive block 121 and the first bolt 122 are detachably connected, it is easier to replace the first spring 123 sleeved on the first bolt 122, preventing the elasticity of the first spring 123 from decreasing and affecting the performance of the mold.
[0064] Figure 5 This is a schematic diagram of a positioning stamping die provided in an embodiment of this application. Figure 5 ,like Figure 5 As shown, the elastic positioning module 23 includes an elastic positioning block 231, a second bolt 232, and a second spring 233. The second cavity 211 includes a fourth cavity portion 2111, a fifth cavity portion 2112, and a sixth cavity portion 2113 connected in sequence, wherein the width of the fifth cavity portion 2112 is smaller than the width of the fourth cavity portion 2111 and the sixth cavity portion 2113.
[0065] In this embodiment, the elastic positioning block 231 is located in the fourth empty portion 2111, and the elastic positioning block 231 can move horizontally within the fourth empty portion 2111. The second bolt 232 is entirely located in the fourth empty portion 2111, the fifth empty portion 2112, and the sixth empty portion 2113, with the first end of the second bolt 232 located in the fourth empty portion 2111 and the second end of the second bolt 232 located in the sixth empty portion 2113. The first end of the second bolt 232 is connected to the elastic positioning block 231, and the second bolt 232 moves with the movement of the elastic positioning block 231. The second spring 233 is sleeved on the outside of the second bolt 232, and the second spring 233 is located in the sixth empty portion 2113. The second spring 233 compresses and shortens or extends and lengthens as the second bolt 232 moves left and right.
[0066] In this embodiment, since the width of the fifth empty portion 2112 is smaller than the widths of the fourth empty portion 2111 and the sixth empty portion 2113, when the second bolt 232 moves to the left along with the elastic positioning block 231, the second spring 233 remains in the sixth empty portion 2113 due to the width of the fifth empty portion 2112, and is further compressed as the elastic positioning block 231 moves to the left. When the second bolt 232 moves to the right along with the elastic positioning block 231, the degree of compression of the second spring 233 gradually decreases.
[0067] In some possible embodiments, the elastic positioning block 231 is detachably connected to the second bolt 232. A cavity is provided at the bottom of the elastic positioning block 231, and the second bolt 232 is inserted into the cavity to fix it to the elastic positioning block 231. Because the elastic positioning block 231 and the second bolt 232 are detachably connected, it is easier to replace the second spring 233 sleeved on the second bolt 232, preventing the elasticity of the second spring 233 from decreasing and affecting the performance of the mold.
[0068] Figure 6 This is a schematic diagram of a positioning stamping die provided in an embodiment of this application. Figure 6 ,like Figure 6 As shown, the upper mold 1 also includes an upper pad 13. The upper pad 13 is located above the upper template 11 and is in contact with the upper template 11. The top surface of the elastic drive block 121 is in contact with the upper pad 13, and the elastic drive block 121 can move left and right along the bottom surface of the upper pad 13.
[0069] In the embodiments of this application, such as Figure 6 As shown, the lower mold 2 also includes a lower backing plate 24. The lower backing plate 24 is located below the lower template 21 and is in contact with the lower template 21. The bottom surface of the elastic positioning block 231 is in contact with the lower backing plate 24, and the elastic positioning block 231 can move left and right along the top surface of the lower backing plate 24.
[0070] Figure 7 This is a schematic diagram of a positioning stamping die provided in an embodiment of this application. Figure 7 ,like Figure 7 As shown, the elastic drive block 121 includes a first drive portion 1211 and a second drive portion 1212 that are in contact with each other. The first drive portion 1211 is located in the first empty space 111 and is connected to the first bolt 122. The second drive portion 1212 extends out of the upper template 11 and includes a first inclined plane.
[0071] In the embodiments of this application, such as Figure 7 As shown, the elastic positioning block 231 includes a first positioning part 2311 and a second positioning part 2312 that are in contact with each other. The first positioning part 2311 is located in the fourth empty part 2111 and is connected to the second bolt 232. The second positioning part 2312 extends out of the lower template 21 and includes a second inclined plane.
[0072] In the embodiments of this application, such as Figure 7 As shown, the first inclined plane and the second inclined plane are parallel to each other, and the first inclined plane and the second inclined plane contact each other during the downward movement of the upper mold 1. When the upper mold 1 moves downward, the elastic drive block 121 moves downward with the upper mold 1, while the elastic drive module 12 moves to the right in the first empty space 111 and the elastic positioning module 23 moves to the left in the second empty space 211, until the elastic positioning module 23 and the fixed positioning block 22 clamp the plate. Then, the upper mold 1 continues to move downward, the elastic positioning module 23 is constrained by the plate and does not move in position, while the elastic drive module 12 continues to move to the right in the first empty space 111, until the bottom surface of the upper template 11 in the upper mold 1 contacts the plate.
[0073] Figure 8 This is a schematic diagram of a positioning stamping die provided in an embodiment of this application. Figure 8 ,like Figure 8 As shown, the upper template 11 includes a contact portion 111. The contact portion is located directly above the lower template 21 between the fixed positioning block 22 and the elastic positioning block 231 in the upper template 11. After the elastic positioning block 231 and the fixed positioning block 22 clamp the plate material located on the lower template 21, the upper template 11 continues to move downward and drives the elastic drive module 12 to move in the first empty space 111 until the bottom surface of the contact portion contacts the plate material.
[0074] In some possible embodiments, the contact portion is a telescopic contact portion. The length of the telescopic contact portion in the vertical direction is adjustable. After the elastic positioning block 231 and the fixed positioning block 22 clamp the plate material located on the lower template 21, the bottom of the contact portion can be made to contact the plate material by adjusting the length of the contact portion in the vertical direction, without needing to continue moving the upper mold downward.
[0075] In some possible embodiments, the positioning stamping die includes an unloading structure. The unloading structure is used to remove the sheet metal from the positioning stamping die after the sheet metal stamping is completed.
[0076] In this embodiment, the cooperation between the fixed positioning block 2 and the elastic positioning module 23 can clamp standard-sized plates as well as plates with dimensional deviations within a certain range. By using this positioning stamping die, the plate can be correctly positioned in the die, thereby ensuring good forming of the plate after the stamping process and avoiding poor plate forming due to plate positioning deviations (such as sharp parts with safety hazards at the edges of the plate).
[0077] This application also provides a material processing apparatus. The material processing apparatus includes the aforementioned positioning stamping die.
