Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

In the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

As shown in fig. 1, a double-ended expansion pipe tip forming die according to an embodiment of the present utility model includes: the double-end tip die fixing seat 1, the double-end tip die 2, the expansion pipe clamping upper jig 3, the first expansion pipe 4, the second expansion pipe 4 and the expansion pipe clamping lower jig 5.

Specifically, the inside central authorities of double-end pointed end mould fixing base 1 are provided with the concave groove, and double-end pointed end mould 2 is placed in the concave groove, and the bottom of tool 3 is equipped with two semi-circular logical grooves on the expansion pipe centre gripping, and the top of tool 3 is equipped with two semi-circular logical grooves on the expansion pipe centre gripping, and the bottom of tool 3 is connected with the top of tool 5 under the expansion pipe centre gripping on the expansion pipe centre gripping, and first expansion pipe 4 and second expansion pipe 4 are placed on the expansion pipe centre gripping in the logical groove of tool 3 and tool 5 under the expansion pipe centre gripping, keep expansion pipe 4 clamp state.

In the embodiment of the present utility model, the double-ended expansion pipe 4 tip forming die further comprises: and an electric coil mounted on the fixing base to heat the double-ended tip mold 2 to a fixed temperature.

In the embodiment of the utility model, the upper clamping jig 3 for the expansion pipe is Z-shaped.

The utility model relates to a double-end expansion pipe 4 tip forming die, which has the following working principle: and taking out the two expansion pipes 4 from the package, and checking whether the end surfaces of the expansion pipes 4 are neat. And placing the expansion pipe 4 into the expansion pipe clamping upper jig 3 and the expansion pipe clamping lower jig 5, and keeping the clamping state of the expansion pipe 4. The double-ended tip mold 2 is fixed in the fixing seat, and the double-ended tip mold 2 reaches a fixed temperature under the action of electric coil heating. The expansion pipe 4 horizontally moves to be close to the double-end tip mould 2 in the clamping state of the clamping jig, and is kept for a plurality of seconds under the action of heat and pressure of the double-end mould, so that one end of the expansion pipe 4 is shaped into a certain shape. The formed expansion pipes 4 horizontally recede under the clamping state of the clamping jig, and the two formed expansion pipes 4 are taken out, so that the tip forming of the two expansion pipes 4 is completed.
