A rotating shaft pressing 8-rib mold and its application method

Abstract

The invention discloses a rotating shaft pressed 8-rib mold and a method for using it, comprising a bottom plate, a lower mold backing plate, a lower module, an upper module, an upper mold pressing block, an upper mold backing plate and a top plate; wherein, the lower mold backing plate is fastened on The bottom plate and the lower module are fastened on the backing plate of the lower mold; the upper module and the lower module are facing each other and are elastically connected to the backing plate of the upper mold through spring bolts. It is fixed on the backing plate of the upper mold, and the backing plate of the upper mold is on the top plate; the top plate is inserted on the spring guide post of the bottom plate through a linear bearing, and realizes vertical sliding cooperation with the spring guide post; the lower and upper modules are respectively embedded There are two beading cores that are inclined at 45°, and each beading core in the lower module is obliquely opposite to an upper beading core in the upper module; There are two beading lines, and each beading line is parallel to the axial direction of the rotating shaft workpiece. The invention 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 bead pressing die, which belongs to the technical field of beading, in particular to a rotary shaft pressing 8-bead die and a use method thereof. Background technique [0002] In the current production process of beading, the beading mold can usually only press 4 ribs at a time. That is, the existing beading mold has only two upper and lower modules and two upper and lower cores. Each module is equipped with a mold core. There are only 2 beads on the mold core, a total of 4 beads, such as figure 1 As shown, in this way, only 4 beads can be pressed each time. However, customers of certain types of rotating shaft products often require the 8-bead pressing process. In the previous pressing-bead production process, in order to achieve the 8-bead pressing, the above-mentioned beading mold is usually used to press the 4 ribs once, and then the operator manually Rotate the shaft 90 degrees, and use the above-mentioned beading die to pre...

AI Technical Summary

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
