For you to analyze the common problems of screw head

A crack on the side of the head

(1) the material is damaged or cracked

(2) the material is very hard

(3) exceeding the processing limit

(4) 1 die

The shape doesn't fit

(1) check the coil surface

(2) check the hardness, tension resistance and distortion of the material

(3) review the processing method

(4) survey tool shape

Head eccentricity

(1) the sliding plate of horizontal or upper and lower die seat is loose

(2) the mounting hole of the die is loose

(3) the shape of 1 die is not good

(4) the compression ratio is too large

(5) poor material section

(6) the roughness of the additive surface of No.2 die is too large

(7) material cutting

Irregular length

(1) adjust the clearance

(2) check the die mounting hole

(3) adjust tool shape

(4) recheck the processing method

(5) adjust the cutter, scissors and die

(6) use a little thicker

(7) investigate the cut-off conveyor part

Insufficient head volume

(1) the material is not cut neatly

(2) the knockout device does not

(3) the pin is bent

(4) conveying machinery

The adjustment of the knockout device and the replacement of the knockout pin have poor right angle

(1) the straight angle of the face of the bottom mold is not good

(2) the surface of the bottom mold is not well trimmed, and the parallelism of the head and the bottom surface is poor

(1) relaxation of skis for horizontal or upper and lower die bases

(2) relaxation of mounting hole of die

(3) the straight angle of the processing surface of the die is not good

(1) adjust the clearance

(2) check the installation hole of punching die

(3) check the No.2 die

The difference between automatic screw heading machine and automatic screw heading assembly machine: the former The fully automatic metal forming equipment for screw production is mainly a cold upsetting equipment for screw processing in screw production; the latter is a newly developed automatic screw assembly tool and equipment in the assembly process of electronic and electrical equipment industry. The emergence of this technology greatly reduces the assembly cost of labor-intensive enterprises and relatively reduces the labor difficulty of enterprises The status quo. Liberate people from mechanical work.
