Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-8 This utility model provides a stamping device for processing automotive parts with easily replaceable molds, including... The main body of the stamping machine is provided with a stamping die 5. Both the upper and lower ends of the stamping die 5 are fixedly connected with sliding locking rails 8. Each sliding locking rail 8 is fitted with a fixed bracket 7, and the fixed bracket 7 is fixedly connected to the main body of the stamping machine. The fixed bracket 7 includes a bearing support 71, and a T-shaped slot 72 is provided on the side of the bearing support 71 away from the main body of the press. The sliding locking rail 8 includes a quick-connect T-shaped seat 81 that is inserted into the inner side of the T-shaped slot 72, and the quick-connect T-shaped seat 81 has a triangular slot 82 arranged in a rectangular array above it, and an elastic latch 76 that is movably connected to the support 71 is also provided above the triangular slot 82.

[0023] Furthermore, the elastic latch 76 includes a rotating latch 761, and one end of the rotating latch 761 passes through a support shaft 763. Both ends of the support shaft 763 are interference-fitted with the bearing support 71, while the end of the rotating latch 761 away from the support shaft 763 is engaged with the triangular slot 82.

[0024] Furthermore, one end of the bearing support 71 is provided with a mounting groove 75 for mounting an elastic latch 76, and the rotating buckle 761 is located inside the mounting groove 75. One side of the mounting groove 75 is integrally provided with an arc-shaped sliding groove 74 opened at one end of the bearing support 71.

[0025] More specifically, the rotating buckle 761 is fixedly connected to an opening and closing lever 764 on the side near the arc-shaped slide groove 74, and the end of the opening and closing lever 764 away from the rotating buckle 761 extends through the arc-shaped slide groove 74 to the outside of the bearing support 71.

[0026] Furthermore, a spring locking piece 762 located inside the mounting groove 75 is fixedly connected above the rotating buckle 761, and the end of the spring locking piece 762 away from the rotating buckle 761 is fixedly connected to the bearing support 71.

[0027] By adopting the above technical solution, the ends of the quick-connect T-shaped seats 81 fixed at the upper and lower ends of the stamping die 5 are inserted into the corresponding T-shaped slots 72 on the bearing support 71. Thus, the stamping die 5 can be easily installed into the stamping machine base 1 by using the fixed card seat 7 and the sliding locking rail 8. Moreover, the spring locking piece 762 pushes the end of the rotating buckle 761 to engage with the triangular card slot 82 on the quick-connect T-shaped seat 81, thereby quickly locking the connection.

[0028] Furthermore, the bearing support 71 is provided with a rectangular array of fixing bolts 73, and the ends of the fixing bolts 73 pass through the bearing support 71 and are fixedly connected to the main body of the stamping machine.

[0029] Furthermore, the main body of the stamping machine includes a stamping machine base 1, and a pneumatic stamping mechanism 3 is fixedly connected above the stamping machine base 1. The pneumatic stamping mechanism 3 has a cylinder push rod 6 at its end, and a connecting pressure plate 4 is fixedly connected below the cylinder push rod 6.

[0030] More specifically, the stamping die 5 includes a lower die 51 and an upper die 52 that are interlocked with each other, and the quick-connect T-shaped seat 81 is symmetrically fixedly connected to the upper part of the lower die 51 and the lower part of the upper die 52 respectively.

[0031] By adopting the above technical solution, when disassembling the stamping die 5, the opening and closing lever 764 is pressed down. The opening and closing lever 764 drives the rotating buckle 761 to rotate around the support shaft 763. The support shaft 763 compresses the spring locking piece 762, causing the end of the rotating buckle 761 to rotate from the triangular slot 82 to the top. Then, the stamping die 5 is moved forward, and the stamping die 5 drives the upper T-shaped seat 81 to separate from the T-shaped slot 72, which facilitates the disassembly of the stamping die 5 and facilitates the quick replacement of the stamping die 5.

[0032] Furthermore, the side of the bearing support 71 away from the quick-connect T-shaped seat 81 is fixedly connected to the connecting pressure plate 4 and the stamping machine base 1 respectively. The bearing support 71 below the lower mold 51 is fixedly connected to the press base 1 by fixing bolts 73, while the bearing support 71 above the upper mold 52 is fixedly connected to the connecting pressure plate 4 by fixing bolts 73.

[0033] Furthermore, the pneumatic stamping mechanism 3 includes a small originating station and a stamping cylinder. The small originating station and the stamping cylinder are connected in series via a pipe and a stamping switch 2 is connected in series. Pressing the stamping switch 2 causes the compressed gas inside the small originating station to enter the stamping cylinder, causing the cylinder push rod 6 in the stamping cylinder to push the connecting pressure plate 4 downward.

[0034] The working principle of this utility model is as follows: In use, the sheet metal is first placed between the lower mold 51 and the upper mold 52. The pneumatic stamping mechanism 3 pushes the lower mold 51 towards the upper mold 52 to stamp the sheet metal. When replacing the stamping mold 5, the opening / closing lever 764 is pressed down. The opening / closing lever 764 drives the rotating buckle 761 to rotate around the support shaft 763. The support shaft 763 compresses the spring locking plate 762, causing the end of the rotating buckle 761 to rotate from the triangular slot 82 to the top. Then, the stamping mold 5 is moved forward. The tool 5 drives the upper T-shaped seat 81 to separate from the T-shaped slot 72. Then, the opening and closing lever 764 is released, and a new stamping die 5 is taken. The quick-connect T-shaped seat 81 on the stamping die 5 is inserted into the inner side of the T-shaped slot 72 from the front. Then, the spring locking piece 762 pushes the end of the rotating buckle 761 to engage with the inner side of the triangular slot 82 through its own elasticity, thereby locking the connection between the quick-connect T-shaped seat 81 and the bearing support 71, which facilitates the quick replacement of the stamping die 5. The structure is simple, the operation is very convenient, and the manual labor intensity is effectively reduced.
