Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, and more specifically, to a two-way composite punching die. Background Art

[0002] Stamping dies can punch various workpieces. They have the advantages of high working efficiency, simple operation, and accurate perforation. Currently, in the production and manufacturing process of auto parts, stamping operation dies are widely used.

[0003] Among auto parts, there are quite a large number of specific types and quantities of trapezoidal workpieces. For example, trapezoidal brackets used in the chassis and suspension systems of automobiles, trapezoidal connecting rods used in the transmission system, steering system, or braking system of automobiles. In order to connect with other components, some trapezoidal workpieces need to be precisely punched at their tops and inclined surfaces respectively. Since the punching positions of these workpieces are different, different punching holes need to be punched sequentially, and the workpieces need to be adjusted between different dies, and additional processes are required to meet the feasibility. The existing punching methods for trapezoidal workpieces have the following problems. First, punching sequentially is difficult to ensure that the positions of the two holes are exactly corresponding, resulting in a decrease in product consistency and a certain rejection rate. Second, the extension of punching time and the increase of processes will lead to an increase in the operation times and waiting times of operators, making it difficult to guarantee the production efficiency.

[0004] In view of this, providing a two-way composite punching die that can punch two orientations of trapezoidal workpieces simultaneously and ensure the high correspondence of the positions of the two holes has become an urgent technical problem in this field. Summary of the Utility Model

[0005] Technical Problems to be Solved

[0027] Embodiment 1:

[0028] Please refer to Figures 1-6 , a two-way composite punching die, including a lower die 1 and an upper die 2. A positioning seat 3 is arranged on the upper surface of the lower die 1, and a workpiece 4 is placed on the positioning seat 3. A guiding mechanism 5 is arranged between the lower die 1 and the upper die 2. An ejecting punching mechanism 6 and a side punching mechanism 7 are adjacently distributed on the lower surface of the upper die 2. A driving member is arranged at the center position of the top of the upper die 2. When the driving member is activated to press down the upper die 2, the ejecting punching mechanism 6 and the side punching mechanism 7 can move synchronously. The ejecting punching mechanism 6 and the side punching mechanism 7 are used for synchronously punching the top and inclined surface of the workpiece 4. Transverse limiting plates 8 are fixedly connected to both the left and right ends of the positioning seat 3. The transverse limiting plates 8 are used to prevent the possible transverse displacement of the workpiece 4 during the stamping process. A pair of assembly grooves 301 are opened at the inner ends of the positioning seat 3. The pair of assembly grooves 301 are respectively distributed at the upper left corner and the lower right corner of the positioning seat 3. Rotating holes coaxial with the assembly grooves 301 are opened on both the positioning seat 3 and the transverse limiting plates 8. A rotating groove 801 is opened on the transverse limiting plate 8, and the rotating groove 801 communicates with the rotating hole on the transverse limiting plate 8. A motor 9 is installed in the assembly groove 301. The output end of the motor 9 is fixedly connected to a rotating shaft 10. A longitudinal limiting plate 11 is arranged in the rotating groove 801. One end of the rotating shaft 10 away from the motor 9 penetrates the rotating hole and is fixedly connected to the longitudinal limiting plate 11. The longitudinal limiting plate 11 can be adjusted to two states: completely located in the rotating groove 801 for placing the workpiece 4 and partially rotated out for limiting the workpiece 4. Please refer to Figure 2 and Figures 5-6 , after a pair of motors 9 are started, they can drive the corresponding longitudinal limiting plates 11 to rotate accordingly, so as to perform the operation of adjusting whether the longitudinal limiting plates 11 limit the workpiece 4 longitudinally. The rotation angle of the motor 9 is controlled by a PLC, and it only rotates 180° and then stops running after a single start.

[0029] The width of the workpiece 4 is adapted to the distance between a pair of lateral limit plates 8, and the thickness of the workpiece 4 is adapted to the distance between the positioning seat 3 and the bottom of the rotating groove 801, ensuring that the workpiece 4 will not have lateral displacement after being placed on the positioning seat 3. The longitudinal limit plate 11 can be rotated to seamlessly fit the upper surface of the workpiece 4. The lower surface of the longitudinal limit plate 11 is engraved with anti-slip lines to increase the friction between the lower surface of the longitudinal limit plate 11 and the workpiece 4, ensuring the limiting effect of the longitudinal limit plate 11 on the workpiece 4. In this way, the workpiece 4 is limited in all directions after being placed on the positioning seat 3, effectively preventing the risk of the workpiece shifting during the stamping process.

[0030] Please refer to Figure 1 , a blanking hole one 302 is provided on the positioning seat 3, and a discharge hole one 101 communicating with the blanking hole one 302 is provided on the lower die 1. A blanking hole two 303 is provided on the inclined surface of the positioning seat 3, and a discharge hole two 102 communicating with the blanking hole two 303 is provided on the lower die 1. The diameters of the blanking hole one 302 and the blanking hole two 303 are larger than the diameters of the punching needles on the top punching mechanism 6 and the side punching mechanism 7, and the diameters of the discharge hole one 101 and the discharge hole two 102 are larger than the diameters of the blanking hole one 302 and the blanking hole two 303, enabling the waste materials generated after top punching and side punching the workpiece 4 to be immediately discharged from each hole body. Moreover, smooth coatings are applied to both the blanking hole one 302 and the blanking hole two 303, effectively preventing the situation of materials getting stuck in the above hole bodies and ensuring the smoothness of the waste material discharge process.

[0031] When using this equipment to perform top punching and side punching on the workpiece 4, first place the workpiece 4 on the positioning seat 3, limit the lateral position of the workpiece 4 through a pair of lateral limit plates 8, start the motor 9 to drive the rotating shaft 10 and the longitudinal limit plate 11 to rotate until the longitudinal limit plate 11 rotates to a state of fitting with the surface of the workpiece 4. At this time, the longitudinal position of the workpiece 4 is also limited. Then start the driving part to press down the upper die 2 so that the top punching mechanism 6 and the side punching mechanism 7 move synchronously, and punch the top and inclined surface of the workpiece 4 synchronously through the top punching mechanism 6 and the side punching mechanism 7. Compared with the prior art, the utility model integrates the side punching mechanism and the top punching mechanism, enabling the top and inclined surface of the trapezoidal workpiece 4 to be accurately punched on the same die, effectively avoiding the position deviation problem caused by sequential stamping in the traditional method, greatly improving the consistency and stability of product quality, thereby effectively reducing the rejection rate. Moreover, the workpiece 4 does not need to be frequently transferred between multiple dies, thus greatly reducing the process conversion time and the waiting time of the operator, and significantly improving the efficiency of the overall production process.

[0032] The above are only the preferred specific embodiments of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
