1. Quality View Appearance View: Firstly, if you can visually check whether there are rust, burrs, indentations, pad wounds and cracks.
A few precision views: the punching process uses a dial gauge and a caliper to check the thickness of the plate and the width of the inner and outer diameters of the ring.
The process calipers are used to view the inner diameter and height dimensions.
The shaping process looks at the inner and outer diameters, the variation of the outer diameter, the depth of the ball, the diameter of the middle circle of the ball pocket, and the radial movement of the ball (measured when the rivet is punched). The caliper and the ball pocket measuring instrument M821 , G904, dial indicator, clearance fixture.
Punch the rivet hole process to view the rivet hole diameter, the intermediate diameter and its offset to the ball pocket; the intermediate diameter and offset are all qualified when passing.
2. Quality analysis of the carrier ring process: The outer diameter scale is mainly because the inner diameter of the concave film is large or worn, and the inner diameter is small. The first step is that the outer diameter of the convex film is small or worn, and the variation of the width is mainly due to the low precision of the film manufacturing; Or the film is deformed and worn.
Forming process: The size of the inner diameter is mainly the slip angle of the punch. The 虺逋 砻娲 砻娲 砻娲 冢 冢 冢 な な な な Υ螅 Υ螅 Υ螅 Υ螅 Υ螅 Υ螅 Υ螅 Υ螅 叨瘸叽绯 叨瘸叽绯 叨瘸叽绯 叨瘸叽绯 叨瘸叽绯 叨瘸叽绯 叨瘸叽绯 叨瘸叽绯钜 ぜ诩 ぜ诩 ぜ诩 ぜ诩 ぜ诩 ぜ诩 ぜ诩 ぜ诩 ぜ诩 ぜ诩 拙 拙 拙 拙 拙 拙 拙 拙 拙 拙 拙 拙 . . . . . . . . . . . . . . . .
The shaping process: the larger the inner diameter of the shaping is, the larger the inner diameter of the molding is. The larger the outer diameter of the shaping is, the larger the blank is, or the outer diameter of the forming process or the shaping plane pressure is large; the deformation is large, and the plastic gap is the first, the production precision of the film is low; The parallelism of the film is not good, the precision of the machine tool is not good, and the thickness of the sheet is too poor. The pocket is mainly the difference between the punch and the pocket of the concave film. The plane is not flattened, firstly, the discharge ring is low or The appearance of wear is formed.
Punching rivet hole process: the rivet hole is small, the punch diameter is small or worn; the rivet hole is mainly the punching discharge ring bias or loose positioning, the punching burr is mainly the punch or the die edge wear; Uneven air gaps.
