Problems solved by technology

[0003] The stamping dies of the prior art have the following defects: each time a screw is punched, five steps of mold opening, loading, stamping mold clamping, mold opening, and demoulding need to be carried out separately, and as many screws as needed to be stamped need to be repeated as many times as necessary. The speed is slow and the efficiency is low, and continuous stamping and forming cannot be performed; secondly, because the round bar is placed between the upper mold and the lower mold when discharging, in this way, if the mold opening range is too small before discharging and when the mold is opened, two The distance between the molds is not enough, it is difficult for people to put the round rod in, but if the mold opening range is too large, the stroke of the punch will be increased when the mold is opened and closed, which will consume more time and further reduce the efficiency. There is a certain danger in discharging the material between the two molds. If the punch is accidentally activated, it may hurt the hands; moreover, because the opening of the lower mold is facing upwards, the demoulding process is too inconvenient

Abstract

The invention discloses a punching die, which comprises a punch (1) and a die shell (2), wherein the die shell (2) comprises two supports (3), a rotating shaft (4), a shifting gear and a rotating barrel (6), the two ends of the rotating shaft (4) are fixed with the two supports (3), the shifting gear and the rotating shaft (4) are registered, a ratchet gear is arranged between the shifting gear and the rotating shaft (4), the rotating barrel (6) is rotatably registered on the rotating shaft (4), a plurality of radial through holes (7) are formed in the rotating barrel (6), the outer openings of the radial through holes (7) are arrayed in the outer circumferential surface of the rotating barrel (6) in rows along the axial direction, the punch (1) is provided with a plurality of rams (8), all of the row of rams (8) are over against the row of radial through holes (7) on the highest position of the rotating barrel (6), and the rotating shaft (4) is also provided with a device for releasing a punching forming screw (10) from the radial through holes (7) in an ejecting manner. The punching die enables the speed of a punching process to be high, the efficiency is high, and safety and convenience are realized.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a stamping mold for stamping screws. Background technique [0002] The stamping die of the traditional stamping screw includes a lower die and an upper die. The upper end of the lower die is provided with a blind hole that matches the shape of the screw, that is, the lower die cavity. The lower end of the upper die is provided with cylindrical pits. The top is provided with hexagonal prism protrusions, and the cavity between the cylindrical recess and the hexagonal prism protrusions constitutes an upper die cavity that matches the shape of the head of the hexagon socket head screw, and the centerlines of the upper and lower die cavities coincide. Fix the lower mold, and put a round rod into the lower mold cavity. The length of the round rod is greater than the height of the lower mold cavity, and the upper mold and the punch are fixed. Drive the punch to make the two molds close to...
