Rapid die centering device for plastically formed upper and lower dies

Abstract

The invention discloses a rapid die centering device for plastically formed upper and lower dies, and the rapid die centering device is characterized by comprising an upper die head (1), a lower die head (3) and a connecting block (2) arranged between the upper die head (1) and the lower die head (3), wherein the central position on the bottom of the upper die head (1) is provided with a threadedconnecting post vertically and downwards extending; the central position on the top of the low die head (2) is provided with a threaded connecting post vertically and upwards extending; the upper plane and lower plane of the connecting block (2) are provided with an upper threaded counter bore and a lower threaded counter bore which are respectively connected with the threaded connecting posts ofthe upper die head and the lower die head in a way of sharing a coaxial line with the upper die head and the lower die head; the upper die head (1), the connecting block (2) and the lower die head (3) are combined through a threaded stud and a bore in a way of centre line superposition; a concave cavity is arranged on the top of the upper die head (1) and is a conical concave cavity the internal diameter of which gradually changes from small to large from bottom to top; and the lower die head (3) is a conical solid body the diameter of which gradually changes from small to large from bottom to top.

Description

technical field [0001] The present invention relates to the rapid mold matching during plastic forming of metal materials, in particular to a fast mold matching device for plastic forming upper and lower molds, which is suitable for plastic forming of parts in mass production and when molds need to be re-aligned due to equipment maintenance, mold maintenance, mold replacement, etc. Applications. Background technique [0002] At present, there is no uniform and suitable device for aligning the upper and lower molds during plastic forming. The operator adjusts the gap between the upper and lower molds based on experience or by painting the upper mold. . Adjust the gap between the upper and lower molds according to the actual size and precision of the trial-formed parts. This requires repeated mold adjustments and mold trials, which is inefficient and wastes part blanks. Sometimes it takes a long time, which affects the improvement of production efficiency and causes unnecess...
