In the stamping production, holes are often punched on the side walls of rotary workpieces (such as cylindrical parts, box-shaped parts, large-sized covering parts and the like), a cantilever type punching die is generally used, a female die of the existing cantilever type punching die is horizontally arranged, the workpieces needing to be punched are sleeved on the female die, and a vertical male die moves downwards under the driving of a press machine to complete the forming of the punched holes.

The CN201921908120.6 discloses a stamping die with a replaceable stamping die head, which comprises a stamping frame, wherein a hydraulic rod is fixedly installed at the bottom of the stamping frame, a support ring fixedly connected with the hydraulic rod is sleeved on the hydraulic rod, the stamping die head is inserted into the bottom of the hydraulic rod, and hanging blocks are fixedly connected to the left side and the right side of the top of the stamping die head. The utility model discloses a, through pulling out two locating pins, let the stamping die head lose the restriction, can rotate to let stabilising arrangement and stamping die head break away from. At present, a lower die holder and a stamping die head (an upper die plate) are separated, the upper die plate is generally and directly fixed on the stamping head for stamping, and meanwhile, the cantilever punching die structure has the following problems that (1) the punching burrs of the waist hole of the original splicing line are large when the cantilever punching die structure is used for stamping splicing materials of a solar water tank shell, the appearance quality of a product is influenced, and potential safety hazards of operators are scratched. (2) One side of the ingredient of the original punching die is not provided with the guide pillar, so that the stress is uneven during punching, and the service life of the die is influenced. (3) The punching process has the phenomenon of strip material (waste is brought upwards). The flying belt is irregular everywhere and still needs to be cleaned manually; the strip material is careless slightly and the circumstances such as gnawing the blade appear, influence product quality, cause the mould to damage or stop production when serious. If the old equipment is directly eliminated, the old equipment is too wasted and needs to be modified.

Disclosure of Invention
