Description

Pipe flaring tool

Technical Field

The utility model belongs to the technical field of air conditioner pipe fitting processing, concretely relates to pipe fitting flaring frock.

Background

The flaring processing of present air conditioner copper pipe needs carry out flaring processing back alone by a flaring core that has the flaring head, carries out the throat processing again to guarantee the external diameter size precision of pipe fitting flaring end, nevertheless in flaring process alone, because the pipe fitting material can bounce-back, leads to pipe fitting flaring end can the adduction after the shaping, and pipe fitting flaring end can guarantee its external diameter size precision, but can't guarantee the straightness that the pipe fitting flared end. Above-mentioned current air conditioner copper pipe flaring processing method not only increases the throat process, increases production manufacturing cost, still exists moreover can't guarantee the pipe fitting flaring end straight, can lead to the unstable problem of follow-up pipe fitting welding quality.

Disclosure of Invention

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a pipe fitting flaring frock, including the flaring core, the one end of flaring core has the flaring head, the periphery of flaring head is provided with the pipe orifice cover, the pipe orifice cover is equipped with the trepanning that can supply the pipe fitting to penetrate, the flaring head is located the trepanning, have between the inner wall of trepanning and the outer wall of flaring head and hold pipe fitting wall and the unanimous gap of width, the flaring end of pipe fitting penetrates the trepanning of pipe orifice cover and stretches into the flaring end lumen of pipe fitting by the flaring core action with the flaring head, when the flaring end of pipe fitting is carried out the flaring to the flaring head, carry out the throat to the flaring end of pipe fitting in step by the pipe orifice cover, the flaring end of pipe fitting adds the gap of holding between the inner wall of trepanning and the outer wall of flaring head when can avoiding the pipe fitting, the inflation adduction warp in when avoiding the pipe fitting, can guarantee pipe fitting flaring end external diameter size precision, can guarantee pipe fitting flaring end.

As the utility model discloses a further improvement, the preferred adoption of the mounting means of mouth of pipe cover, set up the mounting hole on the mouth of pipe cover, the mounting hole sets up in the end of trepanning and communicates with each other with the trepanning, the mouth of pipe cover is adorned in the pipe expanding core through the mounting hole, the outside cover that lies in the mouth of pipe cover on the pipe expanding core is equipped with the spring, support the mouth of pipe cover by the spring and order about the mouth of pipe cover and reset, when the action of pipe expanding core passes through the flaring of pipe expanding head, spring compression supports the mouth of pipe cover and carries out the throat by the mouth of pipe cover to the pipe fitting, flaring and throat are accomplished the back, the pipe fitting separates with the pipe expanding core, the mouth of pipe cover resets under the spring force effect, so.

The spring is installed on the pipe expanding core in a mode that a guide rod is installed and connected at the other end of the pipe expanding core, the spring is sleeved on the pipe expanding core and located between the pipe orifice sleeve and the guide rod, and the whole pipe fitting flaring tool is installed on flaring or necking equipment through the guide rod.

The utility model discloses following beneficial effect has:

the utility model relates to a pipe fitting flaring frock, the flaring end of during operation pipe fitting penetrates the trepanning of pipe orifice cover and by the flaring core action with the flaring head stretch into the flaring end lumen of pipe fitting, the flaring head carries out the flaring when the flaring of pipe fitting is held to the flaring, carry out the throat to the flaring end of pipe fitting by the pipe orifice cover in step, flaring and throat processing are once accomplished, the inflation adduction is out of shape when avoiding the pipe fitting flaring, can guarantee pipe fitting flaring end external diameter size precision, can guarantee pipe fitting flaring end straightness accuracy again, can effectively reduce the production manufacturing cost, improve production efficiency and guarantee production quality.
