Beading die capable of pressing eight ribs on rotating shaft and using method thereof

Abstract

The invention discloses a beading die capable of pressing eight ribs on a rotating shaft and a using method thereof. The beading die comprises a bottom plate, a lower die base plate, a lower die plate, an upper die plate, an upper die pressing block, an upper die base plate and a top plate, wherein the lower die base plate is fastened to the bottom plate; the lower die plate is fastened to the lower die base plate; the upper die plate is opposite to the lower die plate and is in elastic fit connection with the upper die base plate through a spring bolt; the upper die pressing block is arrangedbetween the upper die plate and the upper die base plate, and is fastened on the upper die base plate; the upper die base plate is arranged on the top plate; the top plate penetrates through a springguide post of the bottom plate through a linear bearing so as to be in vertical sliding fit with the spring guide post; two beading die cores obliquely arranged at 45 degrees are respectively embedded in the lower die plate and the upper die plate; each beading die core in the lower die plate is obliquely opposite to the corresponding upper beading die core in the upper die plate; two beading lines are arranged on each beading die core; and each beading line is parallel to the axial direction of the rotating shaft workpiece. The beading die has the advantages of safe and simple operation, high production efficiency, guaranteed quality and the like.

Description

technical field [0001] The invention relates to a rib pressing die, which belongs to the technical field of rib pressing, and in particular relates to a rotating shaft pressing 8-rib die and a use method thereof. Background technique [0002] In the current beading production process, the beading mold can usually only press 4 ribs at a time, that is, the existing beading mold only has two upper and lower modules and two upper and lower mold cores, each module is equipped with a mold core, each There are only 2 beads on the mold core, a total of 4 beads, such as figure 1 As shown, only 4 bars can be pressed each time the bars are pressed. However, some types of rotating shaft products often require 8 ribs to be pressed by customers. In the past production process of ribs, in order to achieve 8 ribs, usually the above-mentioned ribbing mold is used to press 4 ribs once, and then the operator manually presses 8 ribs. The rotating shaft is rotated 90 degrees, and the above-men...

Problems solved by technology

However, there are problems in this production method: the production efficiency is low, the center line of the beading of the mold deviates from the center line of the workpiece at an angle of 45°, resulting in the protruding direction of the beading being not perpendicular to the rotating shaft, which affects the quality, and there is a certain hidden danger of production safety due to manual operation of the rotating shaft
