Process and process of producing hardware nut manufacturers


㈠ Nut Forming:


①, Job Flow:


Ⅰ, cut off: By the inner knife mold and shear knife, the wire cut into the required embryo.


Ⅱ, a punch: by the front punching die, punching Cheng, after punching Rod with, will deform uneven cut off the embryo to shape, and by the rear punching rod will be introduced into the embryo.


Ⅲ, two-punch: the operation clip will be the embryo from a punch clip to two rushing, by the front punching die, punching Cheng, after punching rod with, further the embryo shaping, and strengthen the first punch of the flattening and saturation effect, after which the embryo will be introduced by the rear punch rod.


Ⅳ, three-punch: the operation clip will be the embryo from two to three rushing, by the front punching die, punching Cheng, rear punching rod with, again squeezing the embryo, so that the lower punching energy can be fully molded, and then by the rear punching rod will be introduced into the embryo.


Ⅴ, four-punch: The operation clip will be the embryo from the three-punch clip to four rushing, by the front die, punching Cheng, rear punching rod with, the nut fully molded, and by controlling the thickness of the iron chip to adjust the thickness of the nut, and then by the rear punching rod will be introduced into the embryo.


Ⅵ, five-punch: The operation clip will be the embryo from four to five rushing, by the front die, stripping disk with, will form a complete embryo punching, and so that the broken iron chips into the punching mold under the kernel, and finally complete the formation of the NUT. The head mark of the NUT is formed during this process.


IiHardware nut ManufacturersThe production flow of nuts:


Ⅰ, below level 8 nuts


⑴, plate, pickling, pumping line, molding, tapping, surface treatment, packaging


⑵, Hot Dip Galvanizing: plate. Pickling. Pumping lines-molding-hot-dip galvanizing-tapping. Packaging


Ⅱ, Level 8 nuts


Disk element. annealing. Pickling. Pumping lines-molding-tapping. Surface Treatment-Packaging


Ⅲ, Metric 10, 12, British level 5 or above nuts


Disk element. annealing. Pickling. Pumping lines-molding-tapping. Heat treatment-Surface treatment-packaging


㈡, tapping teeth is the nut that will have been molded, the use of silk attackElectromechanical hardware ScrewsTapping to form the required thread.


① Quality Control: The quality problem that often occurs in the process of tapping teeth is tooth tightness, which is usually caused by the bending of the straight part of the tooth tackle, the passivation of the tooth attack, the difference in the effective diameter, and the lack of the upper and lower runway. In view of the causes of tooth tightness, it is possible to take measures such as orthodontic attack, replacement of tooth attack or adjustment of runway.
