Embodiment Construction
[0015] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:
[0016] Such as Figure 1 to Figure 5 As shown, the present invention is a cutting die for a miniature shaft, which includes a base 1 on which a plurality of lower arc grooves 11 arranged at intervals are arranged, and a detachable movable Module 2, upper arc grooves 23 corresponding to the number of lower arc grooves 11 are provided on the moving module 2, and the upper arc grooves 23 cooperate with the lower arc grooves 11 to form a circular card slot 3, on the upper end surface of the moving module 2 There is a through hole 24 which is perpendicular to the upper arc groove 23 and communicates with the upper arc groove 23, and a retaining spring 4 is placed in the circular retaining groove 3 and the retaining foot 41 of the retaining spring 4 is placed in the through hole 24 of the moving module 2 Inside and locked together by the lock 5; set the lower arc...

The invention relates to a micro-scale shaft cutting die, and mainly aims to solve the technical problem that the planeness of end surfaces of the current micro-scale shaft is worse. The cutting die is characterized by comprising a base with a plurality of spaced lower-camber grooves thereon, wherein a demountable movable module is arranged above the base; upper-camber grooves corresponding to the lower-camber grooves in number are formed on the movable module; the upper-camber grooves and the lower-camber grooves are matched to form round clamping grooves; a through hole perpendicular to the upper-camber grooves and communicated with the lower-camber grooves is formed on the upper end surface of the movable module; and clamp springs are arranged in the round clamping grooves and have clamp feet placed in the through hole of the movable module and buckled with the through hole through lock catches. The invention has the benefits that the micro-scale shaft cut by the cutting die has a more even end surface than that directly punched by a pressing and cutting machine. The micro-scale shaft in the clamp spring can be subjected to more-sophisticated deep processing, so as to meet the dimension requirement of a user; and the production efficiency is greatly improved compared with that of the pressing and cutting machine, and the production cost of the single micro-scale shaft is effectively saved.
Description
technical field [0001] The invention relates to a tooling fixture, more specifically to a cutting mold for a miniature shaft, which is mainly used in the field of production and processing of miniature shafts or precision shafts. Background technique [0002] Due to its high precision requirements for verticality, surface roughness, roundness, and runout, the micro shaft is also called a precision shaft. It is the main accessory of the micro vibration motor. The micro vibration motor is mainly used in mobile phones, toys, health care massagers, etc. Industry; when the existing miniature shaft is produced, basically the stainless steel wire is punched according to the required length by the punching machine, and then the outer diameter of the stainless steel wire is ground by a centerless grinder to make the diameter of the stainless steel wire meet the requirements of use. Requirements; This processing method can meet the requirements for products with low requirements for t...
