[0007] Preferably, the positioning structure consists of guide columns, with two sets of guide columns fixedly installed between the base plate and the L-shaped plate in a front-to-back distribution, and the lifting plate slidingly sleeved on the two sets of guide columns.
[0008] Preferably, pads are fixedly installed on both sides of the lower mold, and screws are provided on the pads. One end of the screw passes through the pad and is threadedly connected to the support plate, so that the lower mold is easy to disassemble and assemble.
[0009] Preferably, a reinforcing block is fixedly installed on the right side of the base plate and the L-shaped plate, and four sets of bases arranged in a rectangular pattern are fixedly installed on the bottom of the base plate.
[0010] Preferably, the drive rotation structure includes an electric push rod, a rack, a connecting column, and a gear. The electric push rod is fixedly installed on the bottom of the base plate, and the free end of the electric push rod is fixedly connected to the rack. One end of the connecting column passes through the base plate and is fixedly connected to the support plate, and the other end of the connecting column is fixedly connected to the gear. The rack and gear are meshed together.
[0011] Preferably, the base plate has an annular opening and a through hole through which the connecting column can pass. A bearing is fixedly installed on the inner wall of the annular opening, and the bearing is interference-fitted with the outer wall of the connecting column. A sliding groove is provided at the bottom of the base plate, and a convex slider is fixedly installed on the top of the rack. The convex slider is slidably installed in the sliding groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] (1) The stable stamping die has a positioning and guiding effect during the downward movement of the lifting plate by setting the guide column, which can ensure that the upper and lower dies can stamp more accurately and stably, thus improving the structural stability and reliability of stamping.
[0014] (2) The stable stamping die, through the cooperation of electric push rod, rack, connecting column, gear, bearing and convex slider, can easily drive the pallet to rotate 180 degrees, making it easy to change the position of the two sets of lower dies. After the workpiece on one set of lower dies is stamped, the other set of lower dies can be placed under the upper die. At the same time, it is easy to change the workpiece on one set of lower dies. Compared with the method of changing the material under the upper die by stopping the operation of the equipment, the efficiency and safety of changing the material are improved. Moreover, the operating space is larger when the die is clamped, which enhances the practicality of the die. Attached Figure Description

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0022] Please see Figure 1-4 This utility model provides a technical solution: a structurally stable stamping die, including a base plate 1, a support plate 2, and a drive rotation structure 5. An L-shaped plate 6 is fixedly installed on the top of the base plate 1. A lifting plate 7 and a hydraulic rod 11 are provided on the L-shaped plate 6. The free end of the hydraulic rod 11 is fixedly connected to the lifting plate 7. An upper die 8 is provided at the bottom of the lifting plate 7. A positioning structure is provided on the base plate 1 and the L-shaped plate 6. The support plate 2 is provided on the base plate 1. Two sets of lower dies 3 are provided on the top of the support plate 2 and are symmetrically distributed from left to right. The drive rotation structure 5 is provided on the base plate 1 and the support plate 2 and is used to drive the rotation of the support plate 2.
[0023] Both sides of the upper mold 8 are fixedly installed with horizontal bars 9. Bolts are provided at the bottom of the horizontal bars 9. One end of the bolt passes through the horizontal bar 9 and is threadedly connected to the lifting plate 7. The hydraulic rod 11 is fixedly installed on the top of the L-shaped plate 6. The positioning structure consists of guide columns 10. There are two sets of guide columns 10, which are fixedly installed between the base plate 1 and the L-shaped plate 6 in a front-to-back distribution. The lifting plate 7 is slidably sleeved on the two sets of guide columns 10. The hydraulic rod 11 is controlled to drive the lifting plate 7 and the upper mold 8 to move downward. The guide columns 10 guide and position the movement trajectory of the lifting plate 7, so that the lifting plate 7 has a positioning and guiding effect during its downward movement. This can ensure that the upper mold 8 and the lower mold 3 can be stamped more accurately and stably, improving the structural stability and reliability of the stamping. Both sides of the lower mold 3 are fixedly installed with pads 4. Screws are provided on the pads 4. One end of the screw passes through the pads 4 and is threadedly connected to the support plate 2. The right side of the base plate 1 and the L-shaped plate 6 is fixedly installed with reinforcing blocks 12. The bottom of the base plate 1 is fixedly installed with four sets of bases 13 distributed in a rectangular shape.
[0024] The driving rotation structure 5 includes an electric push rod 51, a rack 52, a connecting column 53, and a gear 54. The electric push rod 51 is fixedly installed on the bottom of the base plate 1, and its free end is fixedly connected to the rack 52. One end of the connecting column 53 passes through the base plate 1 and is fixedly connected to the support plate 2, while the other end is fixedly connected to the gear 54. The rack 52 and gear 54 are meshed. The base plate 1 has an annular opening and a through hole through which the connecting column 53 can pass. A bearing 14 is fixedly installed on the inner wall of the annular opening, and the bearing 14 is interference-fitted with the outer wall of the connecting column 53. A groove is provided at the bottom of the base plate 1, and a convex slider 15 is fixedly installed on the top of the rack 52. The convex slider 15 is slidably installed in the groove, and then automatically punches the workpiece on a set of lower dies 3. The hydraulic rod 11 drives the lifting plate 7 to move upward, and then the electric push rod 51 drives the rack 52 to move to the left. The rack 52 meshes with and drives the gear 54 to rotate, which in turn drives the connecting column 53 and the support plate 2 to rotate. This allows the two sets of lower dies 3 to be swapped, and the workpiece on one set of lower dies 3 to be loaded. This facilitates the drive plate 2 to rotate 180 degrees, making it easier to swap the two sets of lower dies 3. After the workpiece on one set of lower dies 3 is stamped, the other set of lower dies 3 can be placed below the upper die 8. This also facilitates the replacement of the workpiece on one set of lower dies 3. Compared with the method of changing the workpiece under the upper die 8 by stopping the operation of the equipment, this method improves the efficiency and safety of the workpiece replacement. In addition, the operating space is larger when the die is clamped, which enhances the practicality of the die.
[0025] Working principle: The hydraulic rod 11 drives the lifting plate 7 and the upper die 8 to move downwards, while the guide column 10 guides and positions the movement trajectory of the lifting plate 7. Then, the workpiece on a set of lower dies 3 is automatically stamped. Then, the hydraulic rod 11 drives the lifting plate 7 to move upwards, and then the electric push rod 51 drives the rack 52 to move to the left. The rack 52 meshes and drives the gear 54 to rotate, which in turn drives the connecting column 53 and the support plate 2 to rotate. This allows the two sets of lower dies 3 to be swapped, and at the same time, the workpiece on a set of lower dies 3 is loaded.
[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
