[0020] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0021] like Figures 1 to 3As shown, the utility model provides a flaring and forming device, which includes a base 1, a lifting plate 2, an elastic support member 3 and two flaring and forming dies 4, the two flaring and forming dies 4 are relatively mounted on the base 1, a lifting groove 5 is arranged between the two flaring and forming dies 4, the elastic support member 3 is mounted on the base 1, the lifting plate 2 is mounted on the elastic support member 3, the two side walls of the lifting plate 2 are slidably connected to the inner wall of the lifting groove 5, the elastic support member 3 can extend into the lifting groove 5, the lifting plate 2 can move out of or into the lifting groove 5, and the two flaring and forming dies 4 are both provided with a flaring forming inclined surface 6 on the side away from each other; at the beginning, the elastic support member 3 elastically supports the lifting plate 2 so that the top of the lifting plate 2 extends out of the top port of the lifting groove 5.

[0022] This embodiment is described by taking the example that workpieces 14 are arranged on both sides of the material belt 13. In actual application, the lifting plate 2 supports the flat plate portion of the material belt 13, and the workpieces 14 on both sides of the material belt 13 are respectively located on both sides of the lifting plate 2. After the two workpieces 14 on both sides of the material belt 13 are bent and formed, the material belt 13 will move along the lifting plate 2, so that the two workpieces 14 that have completed bending and forming move to the positions corresponding to the two expansion forming dies 4 respectively, and then the upper mold mechanism of the expansion forming mold of the workpieces on both sides of the material belt applies downward pressure to the lifting plate 2 to drive the material belt 13 and the lifting plate 2 to move downward and compress the elastic support member 3, so that the lifting plate 2 gradually moves into the lifting slot 5 As the material strip 13 moves downward, the expansion molding bevels 6 on the two expansion molding dies 4 will gradually contact the inner side surfaces of the two workpieces 14, causing the two workpieces 14 to gradually open until the lifting plate 2 is in a dead position, thereby completing the expansion molding of the two workpieces 14 on the material strip 13. Finally, the upper mold mechanism releases the downward pressure on the lifting plate 2, so that the lifting plate 2 is driven by the elastic force of the elastic support 3 to lift the lifting plate 2 and the material strip 13, so that the two workpieces 14 on the material strip 13 are separated from the two expansion molding dies 4, so that the material strip 13 can be fed and moved. The expansion molding device has a simple structure, and can complete the expansion molding of the two workpieces 14 on both sides of the material strip 13 at one time in one station, thereby improving the efficiency of the expansion molding of the workpieces 14 on both sides of the material strip 13, reducing the production cost, and shortening the length of the expansion molding mold for the workpieces on both sides of the material strip.

[0023] In this embodiment, both side walls of the lifting plate 2 are provided with first oil storage tanks 7 for storing lubricating oil. In practical applications, the lubricating oil is stored in the first oil storage tank 7, and when the lifting plate 2 is lifted and slid relative to the lifting slot 5, the lubricating oil plays a lubricating role, reducing the friction resistance and wear between the lifting plate 2 and the expansion molding die 4, so that the lifting plate 2 can be lifted and lowered more smoothly and stably.

[0024] In this embodiment, the base 1 is embedded with a guide sleeve, and the bottom surface of the lifting plate 2 is equipped with a guide rod, which is slidably matched with the guide sleeve. During the lifting process of the lifting plate 2, the guide rod and the guide sleeve are slidably matched, thereby improving the lifting stability of the lifting plate 2.

[0025] In this embodiment, the expansion forming device also includes two bending forming dies 8 respectively installed on the base 1, the two bending forming dies 8 are arranged opposite to each other, the lifting plate 2 is located between the two bending forming dies 8, and the bending forming die 8 and the expansion forming die 4 are arranged along the length direction of the lifting plate 2; specifically, a bending guide arc surface 9 is provided on the side of the bending forming die 8 close to the lifting plate 2.

[0026] In actual applications, when the two workpieces 14 at the previous position on the material strip 13 are expanded and formed, the two bending and forming dies 8 respectively bend and form the two workpieces 14 at the latter position on the material strip 13, so that the workpieces 14 are in contact with the bending guide surface 9 and bent and formed along the bending guide surface 9, and then the bent and formed workpieces 14 will move to the expansion and forming die 4 as the material strip 13 moves.

[0027] In this embodiment, a smooth block 10 is embedded in the top surface of the lifting plate 2; the flat plate portion of the material belt 13 contacts the top surface of the smooth block 10, and when the material belt 13 moves along the lifting plate 2, the friction resistance and wear of the material belt 13 are reduced.

[0028] In this embodiment, the top surface of the smooth block 10 is recessed with a second oil storage tank 11 for storing lubricating oil; the lubricating oil is stored in the second oil storage tank 11, and when the material belt 13 moves, the lubricating oil plays a lubricating role, further reducing the friction resistance and wear of the material belt 13 when it moves.

[0029] In this embodiment, the top surface of the smooth block 10 or / and the top surface of the lifting plate 2 is concavely provided with a positioning hole 12. The process hole on the flat plate portion of the material strip 13 is used to communicate with the positioning hole 12. When the upper mold mechanism of the workpiece expansion molding die on both sides of the material strip applies downward pressure to the lifting plate 2, the positioning column of the upper mold mechanism can be inserted into the process hole and the positioning hole 12 to position the material strip 13.

[0030] The utility model also provides a workpiece expansion molding die on both sides of a material strip, comprising the above-mentioned expansion molding device. The workpiece expansion molding die on both sides of a material strip has all the beneficial effects of the expansion molding device, which will not be repeated here.

[0031] All technical features in this embodiment can be freely combined according to actual needs.
