Technical Field
[0001] The utility model relates to the technical field of stamping equipment, in particular to a positioning mechanism for stamping large metal plates. Background Art
[0002] In the stamping process of sheet metal, whether the positioning of the sheet metal in the stamping die is accurate and stable will directly affect the forming effect of the stamping parts. Since the sheet metal is prone to being unstable after being placed in the stamping die, a positioning device that can support the material movably is usually provided in most stamping dies.
[0003] During the use of the stamping die, it is necessary to position the metal plate to prevent the position of the metal plate from shifting during stamping, which affects the stamping effect of the raw material. Some positioning devices on the market have poor stability during use, and the sealing performance during stamping is not good, which affects the normal use of the device. When some devices are in use, the positioning effect is not good, and the impact generated by stamping will cause the metal plate to shake. Summary of the Utility Model
[0004] According to the above technical problems to be solved, a positioning mechanism for stamping large metal plates is provided.
[0005] To achieve the above object, the utility model discloses a positioning mechanism for stamping large metal plates, including a stamping die and a metal plate arranged between the stamping dies. The stamping die includes a fixed die arranged on a base and a movable die located above the fixed die. A first positioning component is arranged outside the stamping die. A second positioning component is arranged at the feeding end of the stamping die. The first positioning component is symmetrically installed on both sides of the stamping die with respect to the feeding direction of the metal plate. A limiting component installed on the base is arranged at the discharging position of the metal plate of the stamping die. Equally spaced positioning grooves are arranged on the edge of the metal plate along the length direction.
[0006] Further, the first positioning component includes a first slide rail arranged parallel to the feeding direction of the metal plate. A slider is slidably installed on the first slide rail. A pressing block corresponding to the shape of the positioning groove on the edge of the metal plate is arranged on the top of the slider. A first cylinder is connected to the side of the pressing block away from the stamping die.
[0007] Furthermore, the pressing block is installed at the same height as the stamping position of the metal plate.
[0008] Furthermore, the second positioning component includes a support plate fixed on the base. A pressing mechanism symmetrically installed on both sides of the metal plate is arranged between the support plate and the stamping die.
[0009] Furthermore, the pressing mechanism includes a first pressing plate and a second pressing plate disposed on the upper and lower sides of the metal plate. The first pressing plate is fixedly installed on the base through a support rod. A second cylinder is installed on the base of the support rod, and the output end of the second cylinder is connected to the second pressing plate.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.
[0020] An embodiment of the utility model, as Figure 1 As shown, the stamping die 2 includes a fixed die arranged on a base 1 and a movable die located above the fixed die, a first positioning component 3 is arranged on the outside of the stamping die 2, a second positioning component 4 is arranged at the feed end of the stamping die, the first positioning component 3 is symmetrically installed on both sides of the stamping die 2 with respect to the feeding direction of the metal plate 6, the stamping die 2 is provided with a limit component 5 installed on the base 1 at the discharge position of the metal plate 6, the metal plate 6 is provided with equidistantly distributed positioning grooves 61 along the edge of the length direction, the positioning groove 61 is U-shaped, and is pressed toward the metal plate by the pressure block of the first positioning component to limit the longitudinal displacement of the metal plate, thereby avoiding offset and shaking during the stamping process, and the second positioning component is used to support the part to be stamped of the large metal plate, ensure the overall flatness of the metal plate, and improve the stamping quality.
[0021] The first positioning assembly 3 includes a first slide rail 31 arranged parallel to the feeding direction of the metal plate 6, a slider 32 is slidably installed on the first slide rail 31, a pressure block 33 corresponding to the shape of the positioning groove 61 on the edge of the metal plate 6 is arranged on the top of the slider 32, and the pressure block 33 is connected to the side away from the stamping die 2 with a first cylinder 34, and the pressure block 33 is installed at the same height as the stamping position of the metal plate 6. Specifically, the first cylinder adopts a pen-shaped cylinder structure. After the metal plate is in place, the pen-shaped cylinder moves to align the pressure block with the positioning groove and press the metal plate to realize the positioning function. The first slide rail is used to adjust the horizontal distance between the pressure block and the limit block. The spacing of the positioning grooves on the edges of metal plates of different specifications can be adjusted in real time to ensure that when the metal plate is engaged with the limit block, the pressure block can be aligned with the positioning groove on the same side, thereby improving the practicality and flexibility of the device.
[0022] The second positioning assembly 4 includes a support plate 41 fixed on the base 1, and a clamping mechanism symmetrically installed on both sides of the metal plate 6 is provided between the support plate 41 and the stamping die 2. The support plate is used to support the part of the metal plate to be stamped to prevent the metal plate from being too large and being affected by its own gravity during the stamping process, causing displacement and affecting the stamping quality.
[0023] The clamping mechanism includes a first pressing plate 42 and a second pressing plate 43 arranged on the upper and lower sides of the metal plate 6. The first pressing plate 42 is fixedly installed on the base 1 through a support rod 44. A second cylinder 45 is installed on the base 1 next to the support rod 44. The output end of the second cylinder 45 is connected to the second pressing plate 43. The first pressing plate is a fixed structure. Before production, the staff manually adjusts the height so that the first pressing plate is located on the top of the metal plate. When the metal plate moves to the bottom of the stamping die for stamping, the second cylinder is activated to make the second pressing plate rise along the support rod to clamp and fix the metal plate.
[0024] The limiting assembly includes a second slide rail 51 vertically arranged with the first slide rail 31, and two groups of limiting blocks 52 are symmetrically installed on the second slide rail 51. A third cylinder 53 fixed to the end of the second slide rail 51 is arranged on the outer side of the limiting block 52, and the output end of the third cylinder 53 is connected to the limiting block 52. The working stroke of the third cylinder is adjusted according to the width of the metal plate 6 to ensure that the metal plate can be engaged and positioned with the limiting block when it reaches the position of the stamping die.
[0025] A limiting groove 521 corresponding to the contour of the metal plate 6 is opened on the surface of the limiting block 52. The shape of the limiting groove 521 is the same as the corner shape of the metal plate 6, and can be rectangular, arc-shaped, etc. In the present embodiment, it is rectangular. The two groups of limiting blocks 52 limit the lateral displacement of the metal plate 6 to avoid offset and shaking during the stamping process.
