Slotted energy-absorbing pin capable of adjusting buckling deformation and preparation method of slotted energy-absorbing pin

The invention discloses a slotting energy absorption pin capable of adjusting buckling deformation and a preparation method thereof. Comprising an energy-absorbing pin and an energy-absorbing piece simulation base which are in threaded connection. The impacted end of the energy-absorbing pin is processed into a semicircular impacted position of the energy-absorbing piece; a slot is formed in the side wall of the energy-absorbing pin; threads are machined on the lower portion of the energy-absorbing pin, and arc transition is machined between the threads and the open groove. The bottom of the energy-absorbing pin is provided with a connecting energy-absorbing piece slot; the inner top end of the energy-absorbing pin is processed into an inner semicircular design; the energy-absorbing piece simulation base comprises a round hole and a hollow round pipe, the round hole with the built-in thread is located in the center of the upper end face of the energy-absorbing piece simulation base and is in threaded connecti
