Abstract
A punching device comprises a pushing pole, an adjusting portion, a supporting portion, and a spring. The pushing pole comprises a first threaded end and a second threaded end. The adjusting portion defines a screw hole therein, through which the adjusting portion is fixed to the first end of the pushing pole. The supporting portion is located on the pushing pole, with the pushing pole passing through a through hole in the supporting portion. The spring is disposed around the pushing pole, with two ends respectively abutting against the adjusting portion and the supporting portion.
Claims20
A punching device, comprising:
- a pushing pole, comprising a pole body having a first threaded end and a second end, and a flange is fixed on the pole body between the first end and the second end;
- a supporting portion is located on the pushing pole, between the flange and the first end;
- an adjusting portion fixed on the first end of the pushing pole which defines a screw hole therein;
- a spring disposed around the pushing pole, and between the supporting portion and the adjusting portion.
A punching assembly, comprising:
- a punching equipment, comprising a hammer, a supporting platform opposite to the hammer, and a pressing block disposed on the supporting platform for pressing a workpiece;
- a punching device, comprising:
- a pushing pole, comprising a pole body having a first threaded end and a second end, and a flange is fixed on the pole body between the first end and the second end;
- a supporting portion is located on the pushing pole, between the flange and the first end;
- an adjusting portion fixed on the first end of the pushing pole which defines a screw hole therein;
- a spring disposed around the pushing pole, and between the supporting portion and the adjusting portion;
- and
- a punch fixed on the second end of the pushing pole.
A punching assembly, comprising:
- a punching equipment comprising a supporting platform for placement of a workpiece, and a hammer spaced from said supporting platform for providing punching power toward said workpiece placed on said supporting platform;
- and
- a punching device disposed between said hammer and said supporting platform so as to accept said punching power from said hammer for punching said workpiece, said punching device comprising a pushing pole extending and movable between said hammer and said supporting platform, an adjusting portion fixed at a first end of said pushing pole to engage with said hammer for accepting said punching power from said hammer and urge said pushing pole to move toward said workpiece, a punch fixed at a second end of said pushing pole opposite to said first end thereof to move together with said pushing pole for punching said workpiece, a supporting portion disposed beside said second end of said pushing pole to confine an elastic element around said pushing pole between said supporting portion and said adjusting portion, a relative fixed position of said adjusting portion onto said pushing pole being changeable so as to adjust resilience of said elastic element between said supporting portion and said adjusting portion.
