Description

Technical Field

[0001] The utility model belongs to the technical field of PFA bead-in joint crimping, and in particular relates to a PFA bead-in joint crimping tool. Background Art

[0002] PFA beaded fittings are a special type of fittings that resemble beads in appearance, hence the name "beaded fittings". Made of polytetrafluoroethylene (PFA) material, this fitting has excellent corrosion resistance and high temperature resistance, so it is widely used in various industrial fields.

[0003] The PFA bead-in connector crimping tool is a tool specifically used for connecting and installing PFA bead-in connectors and PFA hoses. It mainly includes a main body, a pipe clamp and a bead-in connector for installation and use. It is suitable for British 1 / 4-1 inch outer diameter pipes.

[0004] The existing bead-in connector crimping tool first places the PFA bead-in connector on the bead-in connector holder, and then the end of the holder is equipped with an end cap to expand the diameter of the PFA hose orifice. Then the PFA tube is inserted into the pipe holder, the pipe holder locking mechanism is fixed with a hook, and the pipe holder is locked by rotating the shaft. Finally, the handle is rotated to drive the bead-in connector into the PFA tube.

[0005] In the actual beading process, the locking mechanism of the pipe clamp fixed on the main body has a complex structure and high processing cost; the end cap is easy to fall off and break; the pipe clamp is made of polyurethane, which is easy to yellow and harden. Utility Model Content
