Description
Technical Field
The utility model relates to an elastic flaring head of a flaring mechanism.
Background
After the expansion of the general long U-shaped pipe is finished, a flaring process is carried out on the pipe opening, namely flaring and flanging forming are carried out on the pipe opening, and the flaring and flanging forming process has the main function of supporting welding flux in the subsequent welding process, so that the welding machine is prevented from running off and cannot weld well.
The flaring is realized through supporting flaring head, because the copper pipe has the phenomenon of difference in height, and current flaring head is connected with the mechanism that drives its removal rigidly in addition, so can often appear following phenomenon: when the copper pipe is lower than the standard height, the pipe orifice cannot be expanded in place, so that the cup opening is too small; when the copper pipe is higher than the standard height, the pipe orifice is broken, and the subsequent welding process is influenced.
Disclosure of Invention
The utility model aims to solve the technical problem that overcome prior art's above-mentioned defect and provide an elasticity flaring head of flaring mechanism, make it can adjust the flaring head flaring degree of depth.
The utility model provides a technical scheme that above-mentioned technical problem adopted does:
an elastic flaring head of a flaring mechanism comprises a flaring head, a spring, a sleeve and a connector; one end of the flaring head penetrates through one end of the sleeve and is limited by the sleeve to the other end of the flaring head, the connector is connected with the other end of the sleeve, the spring is arranged between the other end of the flaring head and the connector, and the upper end face and the lower end face of the spring are respectively contacted with the lower end face of the connector and the upper end face of the flaring head and are positioned in the sleeve.
When the flexible flaring head is used, the flexible flaring head is arranged on a moving plate of the flaring mechanism through the connector, and the driving transmission mechanism of the flaring mechanism drives the moving plate to move in the horizontal direction or the vertical direction, so that the flexible flaring head is driven to move in the horizontal direction or the vertical direction. When the moving plate moves in the vertical direction, the flaring head is driven to flare a workpiece such as a copper pipe.
Preferably, the connector is in threaded connection with the sleeve, so that the connector can be conveniently detached.
Preferably, the end of the flaring head and the end of the sleeve are limited by the mutually arranged steps, so that the manufacturing and the assembly are easy.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1 and 2, an elastic flaring head of a flaring mechanism comprises a flaring head 1, a spring 2, a sleeve 3 and a connector 4.
One end of the flaring head 1 penetrates through the sleeve 3, the other end of the flaring head 1 is provided with a limiting step 101 and is limited by a step 301 at one end of the sleeve 3, the connector 4 is in threaded connection with the other end of the sleeve 3, the spring 2 is positioned between the flaring head 1 and the connector 4, and the upper end surface and the lower end surface of the spring are respectively in contact with the lower end surface of the connector 4 and the upper end surface of the flaring head 1 and are positioned in the sleeve 3.
The elastic flaring head is arranged on the moving plate 6 through the connector 4, the moving plate 6 is driven to move in the horizontal direction or the vertical direction through a driving transmission mechanism (not shown), and when the elastic flaring head moves in the vertical direction, the flaring head 1 is driven to flare the copper pipe.
A spring 2 is arranged between the flaring head 1 and the connecting head 4, and the spring sets a certain pretightening force, namely the spring has a certain precompression amount. When the friction resistance is smaller than the sum of the force applied to the flaring head by the driving transmission mechanism and the pre-tightening force of the spring, the driving transmission mechanism drives the connector 4 to apply pressure to the flaring head through the spring, so that the flaring head descends to flare the pipe opening; on the contrary, if the friction resistance is larger than the friction resistance, the pre-tightening force of the spring can be overcome, although the driving transmission mechanism can drive the connecting head 4 to descend, the flaring head cannot be driven to descend, but the spring is further compressed, so that the flaring of the pipe orifice cannot be continued.
The height difference of the orifices of the workpiece of the heat exchanger related to the embodiment is within the tolerance range, and is larger than the tolerance range and is not considered in the embodiment, so the descending distance of the expansion head is set according to the position of the lowest orifice. The flaring head 1 can be lowered for a set distance to ensure the complete flaring formation of the low pipe orifice; and for the pipe orifice higher than the standard height, the flaring forming of the pipe orifice is finished when the pipe orifice does not fall to the set distance, and the pipe orifice is inevitably cracked if the flaring head continues to fall to the set distance according to the conventional method, but after the spring 2 is added, the frictional resistance during the falling overcomes the pretightening force of the spring, and the flaring head does not continue to fall to crack the pipe orifice.
In order to better control the pretightening force of the spring, a gasket 5 is additionally arranged, and the thickness of the gasket 5 can be adjusted according to actual needs.
