Abstract

The invention discloses a hexagon head bolt hot heading forming die. A step hole with the wide upper portion and the narrow lower portion is formed in a forming die fixing base from top to bottom in apenetration manner. The step hole is internally provided with a T-shaped combined forming die. A horizontal arm of the T-shaped combined forming die sleeves the step position of the step hole. A vertical arm of the T-shaped combined forming die extends out of the lower surface of the forming die fixing base. The T-shaped combined forming die is provided with a T-shaped blind hole from top to bottom. A piece pushing device is arranged in the T-shaped blind hole. The upper surface of the T-shaped combined forming die is provided with a cushion plate, and the cushion plate is arranged at the upper portion of the step hole. The lower end of the T-shaped blind hole in the T-shaped combined forming die is provided with a hexagon head forming die. A lower die comprises a lower die base and a lower die fixing base fixed to the lower die base, a lower die core is sleeved with the lower die fixing base, and a second straight hole is coaxially formed in the lower die core and the step hole and internally provided with a lower ejection rod. The lower ejection rod is driven by a drive mechanism to move up and down.

Description

technical field [0001] The invention relates to bolt processing, in particular to a hexagon head bolt hot pier forming die and a processing technology thereof. Background technique [0002] The hexagonal head of the bolt is formed by hot stamping. For example, the patent No.: CN201420854510.0 discloses a multi-station forming mold for bolt hot pier, which is characterized in that: the pier thick upper die, the forming upper die are connected with the upper die base arranged on the upper template, and the upper template It is fixed on the slider of the press, and drives its movement with the movement of the slider. On the upper template, there are also a first upper ejector rod, a second upper ejector rod, a mold handle and a punching rod; the pier thick lower die, The forming lower mold is arranged on the lower mold base of the lower template, and is set opposite to the pier thick upper mold and the forming upper mold respectively, and a lower ejector rod is movable in the ...
