The invention belongs to the technical field of pipe processing, in particular to a variable-diameter flaring device for pipe processing. The problem that when a pipe variable-diameter flaring deviceis used for flaring a hose, axial extrusion deformation of the hose is prone to being caused, and the flaring effect is affected is solved. By means of the following scheme, the variable-diameter flaring device comprises a machine base, the inner wall of one side of the machine base is provided with a mounting hole, a driven gear is sleeved with the inner wall of the mounting hole, the inner wallof one side of the driven gear is provided with a lantern ring chute, a lantern ring is slidably connected to the inner wall of the lantern ring chute, the outer wall of one side of the lantern ring is provided with a push ring in a welded manner, and the outer wall of one side of the push ring and the inner wall of one side of the driven gear are each provided with a return spring in a welded manner. By means of the variable-diameter flaring device, it can be ensured that a punch pin is pressed into the inside of the hose, the effect of stopping the pipe from generating axial wrinkles and affecting flaring during punching with the punch pin can be achieved, the probability of occurrence of the pipe pulling damage during the flaring can be effectively reduced, pipe deformation caused by too large friction force is facilitated, and the local deformation of the pipe is effectively prevented.
Description
technical field [0001] The invention relates to the technical field of pipe processing, in particular to a diameter reducing and expanding device for pipe processing. Background technique [0002] When the pipe is installed, it is often necessary to socket one end of the two pipes. In order to facilitate the socketing tooling of the pipe, the inner diameter of one end of the pipe needs to be enlarged. For the hose, due to the special material of the hose, the flaring It is easy to cause deformation and damage to the hose when changing the diameter. [0003] After searching, the patent of CN108527829A after the Chinese patent publication discloses a hose flaring device, including a base, a hose clamping unit and a flaring unit. The hose clamping unit is arranged on the base, and the flared The unit can move relative to the hose clamping unit, and the flaring unit has a flaring die for flaring the hose. The hose flaring device in the above-mentioned patent still has many shor...
