[0046] When performing stamping and loading, first, the second mandrel 30 is withdrawn by the first driving mechanism 40, and then a square tube is sleeved on the first mandrel 20 manually. At this time, the stripping assembly 50 located on one side of the first mandrel 30 moves towards the first mandrel 20 through the stripping rod 52, so as to press the square tube against the side wall of the first mandrel 20. At this time, the second mandrel 30 is inserted into the square tube by the first driving mechanism 40 and spliced with the first mandrel 20 to complete; then the upper cover 60 is driven by an external driving mechanism to press down, and at the same time, the movable plate 61 is driven by the second driving mechanism 62 to move, so that the pressing head 85 on the movable plate 61 drives the clamping plate 82 to clamp and fix the product through the cooperation of the second guiding surface 851 and the first guiding surface 821. Then, the punch 70 is continuously driven by the upper cover 60 to move downward, and the stamping process of the square tube is completed.

[0047] When taking the material after forming, first, the upper cover 60 is driven by an external driving mechanism to move upward. At this time, the clamping plate 82 in the fixing assembly 80 is reset under the action of the spring 84, and at the same time, the upper cover 60 drives the punch 70 to move upward; then the stripping rod 52 located on the side of the first mandrel 20 presses against the square tube towards the first mandrel 20. Then, the second mandrel 30 is withdrawn by the first driving mechanism 40. Then, the pushing rod located on the side of the second mandrel 30 moves towards the direction of the first mandrel 20 and pushes the square tube to complete lateral stripping between the square tube and the first mandrel 20. Finally, the pushing assembly 90 pushes the product out along the first mandrel 20, and the product can be taken manually.

[0048] The design focus of the present utility model lies in: through punching holes are provided on the outer side of the first mandrel; and the second mandrel is arranged on the base so as to be able to move horizontally back and forth and is located beside the inner side of the first mandrel, and the second mandrel and the first mandrel are arranged to be spliced together; so that through the spliced structure, after stamping is completed, the second mandrel without the punching hole structure can be horizontally withdrawn first, and then at least two stripping assemblies are provided. At least two stripping assemblies are respectively arranged on the base and located on the left and right sides of the first mandrel and the second mandrel, so that the product can be pushed towards the direction of the first mandrel by the pushing assembly located on one side of the second mandrel, so as to strip the formed shape from the punching hole, which is convenient for the process of taking out the product and effectively improves the overall forming efficiency. There will be no interference during the material taking process, avoiding the problem that the formed part is deformed due to interference collision, and ensuring the processing quality.
