1. Metal cutting. The metal cutting of the hose joint is mainly turning, the traditional metal cutting machine tool is used. A large number of standard pipe joints are also processed on automatic CNC lathes multi-axis automatic machine tools.

 According to different profiles different types of pipe joints, some auxiliary cutting processing is required, such as the common six-sided angle, planer milling machine milling flat flat hexagon wrench; wrench; some sealing joint grinding machine for the sealing surface; the precision of the pipe processing lock the nuts on the bed with the shape clamped traveller lock.

  2. No cutting. In order to improve the utilization rate of metal materials, save raw materials improve production efficiency. In the process of hose joints, metal cutting should be minimized. When conditions permit, the groove outside the core can be rolled. The external thread can be pushed out by the rolling machine, the internal thread can be formed by the tapping machine. When using air conditioning hoses some medium low pressure oil pipe joint cores, metal pipes should be used as much as possible, the end of the molding machine mold is used to form the core of the sealed end. The coating is made of low-carbon thin steel plate. Some core joint types, such as the radial size of the gap, the core is too long needs to be bent into a corner of the curved die, can be used in the welding process.

    The most widely used pipe joints without cutting are hot forging cold extrusion processes. Suitable for hot forging cold extrusion processes. The utility model is suitable for large-scale production of standard pipe joints, can greatly improve the utilization rate of metal materials, improve the mechanical strength, production efficiency production cost of materials. Generally, a forging press with a certain tonnage is used to press the cut profiles to the basic shape through hot forging coolant, a small amount of metal cutting can obtain the required precision shape of the pipe joint. Especially suitable for the processing of nuts jackets in pipe joints.

      3. Heat treatment. Hose joints generally do require heat treatment, as long as the appropriate metal material is selected. However, the pipe joints of individual parts the pipe joints with special requirements sometimes need to be quenched, annealed chemically heat treated before after metal processing to improve the quality improve the service life safety of the pipe joint parts.
