Nut processing technology of Dongguan nut manufacturer

The nut processing sequence of the Dongguan nut manufacturer is as follows: car end face-center hole-rough turning outer circle-chamfering-drilling-car inner hole-car internal thread-pre-cutting-inverted Angle-cut off-install the indexing head and three-jaw self-centering chuck-clamp and align the workpiece-install the milling cutter-visually check the tool-trial milling two opposite sides-pre-check the opposite side size- Reverse the workpiece 180 degrees and mill the same opposite side again-measure the size of the opposite side again-adjust the length and milling position-milling in turn according to the requirements of equal division-inspection

For the positioning and clamping of the workpiece, the Dongguan nut manufacturer chooses an indexing head, a three-jaw self-centering chuck with a threaded mandrel, and uses a dial indicator to align the tool. Choose a 90-degree 45-degree external turning tool, *3mmA Type CA6140 lathe and X6132 horizontal universal milling machine are selected as the equipment for center drill, twist drill*27mm, external turning tool 3mm cut-off tool, inner hole turning tool, thread turning tool, and three-face milling cutter.

Bolt: A type of fastener consisting of two parts: head and screw (cylinder with external thread). Yamato drill tail wire needs to be matched with a nut to fasten and connect two through holes Components.

This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.

Classification of bolts for Dongguan nut manufacturers

1. According to the force mode of the connection, the bolts used for reaming holes and those with reaming holes should be matched with the size of the holes and used when subjected to lateral force.

2, according to the shape of the head, round head, square head, countersunk head, etc. Generally, the countersunk head is used in the place where the surface after the connection is required to be smooth without protrusions because the countersunk head can be screwed into the part. It can also be screwed into the part. The tightening force of the square head can be larger, but the large size head is the most commonly used. In addition, in order to meet the need for locking after installation, there are large holes in the head and holes in the drill tail screw. These holes It can make the bolt not loose when it is vibrated. Some bolts without threaded polished rods should be called thin waist bolts. This kind of bolts is conducive to variable-force joints. There are special high-strength bolt heads that will be larger in size. There are also changes.
