[0023] In this embodiment, the mold frame assembly 2 includes a motor 21 fixed in the base 1, and the motor 21 is connected to a support plate 23 sliding on the base 1 through a screw 22. C-shaped mold frames 24 are provided on both sides above the support plate 23, and the front mold assembly 3 and the rear mold assembly 4 are respectively mounted in the front and rear of the C-shaped mold frame 24.

[0024] As shown in the accompanying drawings, the front mold assembly 3 of this embodiment includes a front lower mold assembly 31 and a front upper mold assembly. The front lower mold assembly 31 is mounted below the C-shaped mold frame 24, and the front upper mold assembly slides between the slide rails 32 on the upper edge of the C-shaped mold frame 24. The front upper mold assembly includes a front upper mold slider 33 slidably embedded in the slide rail 32. The upper part of the front upper mold slider 33 is connected to the front upper mold base plate 35 through a front guide column mechanism 34. The upper part of the front upper mold base plate 35 is connected to the front upper mold cover plate 36. A front upper mold cylinder 37 is provided at the bottom of the front upper mold cover plate 36. The front end of the front upper mold cylinder 37 is connected to the front upper mold striking block 38. The front upper mold striking block 38 is pulled by the front upper mold cylinder 37 and moves to the top of the corresponding front upper module according to the process instructions. When the punch assembly impacts the front upper mold cover plate 36, it impacts the corresponding front upper module. The lower part of the front upper module corresponds to the front lower module 39 on the front upper mold base plate.

[0025] The front and rear mold assembly structures are the same and are no longer marked. The rear mold assembly in this embodiment includes a rear lower mold assembly and a rear upper mold assembly, the rear lower mold assembly is mounted below the C-shaped mold frame, the rear upper mold assembly slides between the slide rails on the upper edge of the C-shaped mold frame, the rear upper mold assembly includes a rear upper mold slider slidably embedded in the slide rail, the upper part of the rear upper mold slider is connected to the rear upper mold base plate through a guide column mechanism, the upper part of the rear upper mold base plate is connected to the rear upper mold cover plate, the bottom of the rear upper mold cover plate is provided with a rear upper mold cylinder, the rear end of the rear upper mold cylinder is connected to the rear upper mold impact block, the rear upper mold impact block is pulled by the rear upper mold cylinder and moves to the top of the corresponding rear upper module according to the process instructions, and impacts the corresponding rear upper module under the impact of the rear punch assembly on the rear upper mold cover plate, and the lower part of the rear upper module corresponds to the rear lower module on the rear upper mold base plate.

[0026] In this embodiment, the front die assembly is equipped with ten sets of front upper die cylinders 37, while the rear die frame assembly is equipped with eight sets of rear upper die cylinders. A front return spring 310 is installed within the front guide post mechanism 34 to reset the front upper die cover plate 36 after the punch assembly presses it downward. Similarly, a rear return spring is installed within the rear guide post mechanism.

[0027] When the adjustable die assembly mechanism of a double-punch punch press of this embodiment is in operation, the flywheel assembly of the punch press impacts the workpiece to be processed placed in the die assembly on the die frame assembly through the punch assembly. The die assembly is supported by a guide column mechanism, and the guide column mechanism can slide on the die frame assembly through a slider at the bottom. The guide column mechanism plays a supporting and guiding role. The die assembly is divided into an upper and a lower die. The upper die cover plate connected to the upper die bottom plate is used to withstand the downward pressure impact of the punch assembly. The upper die cylinder below the upper die cover plate pushes the striking block to move. The initial position of the striking block is in the gap between the corresponding upper modules, and multiple groups of cylinders and striking blocks are arranged below the upper die cover plate. When it is necessary to impact the upper module at a certain position, the corresponding cylinder is controlled to extend, and the striking block moves to the upper part of the corresponding upper module below the upper die cover plate. At this time, the punch assembly is operated to punch the upper die cover plate downward, and then punch the upper module. Under the impact of the upper and lower modules, the stamping process of the workpiece to be processed clamped between the two is completed.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
