Embodiment Construction

[0025] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

[0026] like Figure 1 to Figure 5 As shown, the manufacturing method of the fastener radial marking of the present embodiment includes the following steps:

[0027] 1. Extend the fastener vertically into the movable mold cavity 31 of the lower mold 1 of the processing device, so that the lower end of the fastener is connected to the fastener installation cavity 18 of the lower mold 1;

[0028] 2. The upper mold 2 of the processing device moves downward relative to the lower mold 1, so that the bottom surface of the upper mold 2 touches the top surface of the movable mold body of the lower mold 1, so that the movable mold body moves downward relative to the limit cavity of the lower mold 1 to The bottom opening of the movable mold cavity 31 is matched with the opening of the fastener installation cavity 18 to form a lower mold cavity, and the...

Abstract

A method for manufacturing a radial identification of a fastener, comprising the steps of vertically extending the fastener into a movable mold cavity of a lower mold of a processing device, so that the lower end of the fastener is connected in the fastener installation cavity; The upper mold moves downward relative to the lower mold, and the upper mold cavity of the upper mold is combined with the lower mold cavity to form a fastener forming cavity that matches the shape of the fastener; the raised part on the side wall of the movable mold cavity follows the movement The side wall of the mold cavity moves toward the fastener and presses radial marks on the side wall of the fastener; the upper mold moves upward, and the reset mechanism drives the movable mold body to move to the upper cavity of the limit cavity, and the side of the movable mold cavity Wall separates from fastener; remove fastener from movable cavity. The advantage of the present invention is that radial marks are processed on the side walls of the fasteners by the movable module clamping, which overcomes the technical problem that the upper and lower mould structures can only process marks on the top and bottom of the parts, and the diameter is processed through the upper and lower mould structures. to the identification.

Description

technical field [0001] The invention relates to the technical field of manufacturing a radial marker of a fastener, in particular to a manufacturing method of a radial marker of a fastener. Background technique [0002] For the manufacturer's identification, performance level identification, etc. required by fasteners, the original cold heading process is upsetting on the axial head end face of the fastener and the tail of the part. For the axial head end face of the fastener, the tail of the part cannot be upset, which should be reflected in the radial direction of the fastener, and the unthreaded part of the side polished rod should be processed by the secondary process of planetary thread rolling, rolling or stamping. However, this method has the problems of many processing steps and low efficiency, so the method needs to be further improved. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a method for manufac...
