Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is to this hair
Bright explanation and the invention is not limited to following embodiments.
Embodiment.
Referring to Fig. 1-Fig. 7, connecting bushing processing technology before the turning machine of the present embodiment more economicalization, the technique combines cold
It squeezes and machining, simple process process is as follows:
(1) blanking: raw material are wire rod, and φ 20.8mm diameter is suitable for cold headers blanking；High production efficiency.
(2) shaping: material jumping-up shaping, being continuously shaped into φ 29.8mm by φ 20.8mm is to stretch Kong Xu to prepare.
(3) stretch hole: specific punch die structure, backward extrusion shaping blank, due to preamble shaping, inside and outside concentricity can achieve φ
Within 0.2mm, 30 ± 0.1mm of outer diameter φ, 20 ± 0.1mm of internal diameter φ.
(4) Vehicle Processing: instrument lathe processes both ends of the surface, to guarantee overall length 32+0.3mm and hole depth 7.5+0.3mm.
