[0028] In order to further explain the technical solution of the present utility model, the present utility model will be elaborated in detail through specific embodiments below.

[0029] Referring to Figures 1-6 as shown, the present utility model discloses an automatic flanging and pressing mechanism, which includes a base 1, a lower die 2, a transfer fixture 3, an upper die 4, a lifting bracket 5 and a flanging assembly;

[0030] The lower die 2 is fixedly installed on the base 1 and is provided with a circle of flanging flanges 21 for cooperating with the side fabric a for flanging;

[0031] The transfer fixture 3 is movably inserted through the flanging flange 21 to cooperate within the lower die 2 for sleeving the side fabric a;

[0032] The upper die 4 is lifted and lowered to cooperate above the lower die 2 for fitting the end face fabric b; when the lower die 2 and the upper die 4 are closed, the side fabric a and the end face fabric b are pressed together;

[0033] The lifting bracket 5 is sleeved on the peripheral surface of the lower die 2 and is lifted and lowered to cooperate above the base 1;

[0034] A plurality of groups of flanging assemblies are arranged on the lifting bracket 5; the flanging assembly includes an outward turning gripper 6 for flanging and a first driving device 7 for driving the outward turning gripper 6 to move horizontally.

[0035] Through the above solution, refer to Figures 5-6 , after the side fabric a of the present utility model is sleeved on the transfer jig 3, the transfer jig 3 with the side fabric a is placed into the lower mold 2. A part of the fabric at the upper end of the side fabric a will be higher than the flanging flange 21 of the lower mold 2. At this time, the lifting bracket 5 drives each flanging component to rise until the outer turning gripper 6 is higher than the upper end of the side fabric a. The first driving device 7 drives the outer turning gripper 6 to move towards the side fabric a until it reaches the inner side of the side fabric a. Then, the lifting bracket 5 drives each flanging component and its outer turning gripper 6 to synchronously descend until they contact the upper end of the side fabric a. Then, the first driving device 7 drives the outer turning gripper 6 to move towards the outer side of the side fabric a. Each outer turning gripper 6 drives the upper end of the side fabric a to turn outwards along the flanging flange to complete automatic flanging. Finally, the upper mold 4 with the end face fabric b attached descends and closes with the lower mold 2 to complete the pressing of the side fabric a and the end face fabric b. Thus, the present utility model can realize the automatic flanging and pressing of the side fabric a and the end face fabric b, and through the synchronous lifting and lowering of the flanging components driven by the lifting bracket 5, the consistency of the height change of each flanging component is maintained, thereby ensuring that the dimensions are consistent when each flanging component performs the flanging action, improving the production efficiency and the consistency of the product, and reducing the rejection rate.

[0036] The following shows specific embodiments of the present utility model.

[0037] The above-mentioned lower mold 2 is fixed on the base 1 through the lower mold bracket 8. The lower mold bracket 8 is composed of several support rods, and the lower mold 2 can be fixed at an appropriate height.

[0039] The present utility model further includes an ejection mechanism 9 arranged in the lower mold 2. The ejection mechanism 9 outputs a linear motion upwards and acts on the transfer jig 3 to eject the transfer jig 3, making it more convenient for employees or a robotic arm to take away the transfer jig 3 with the fabric after pressing. In this embodiment, the above-mentioned ejection mechanism 9 is a vertically arranged air cylinder, and an ejection block is installed at the output end of the air cylinder.

[0040] Furthermore, a support plate 10 for supporting the transfer jig 3 is arranged in the lower mold 2, and the support plate 10 is provided with a through hole 101 for the output end of the ejection mechanism 9 to pass through movably.

[0041] The above-mentioned upper mold 2 can be the pressing head of a hot press, and thus cooperate with the lower mold 4 to achieve hot press sealing when closing the mold.

[0045] The first driving device 7 is two groups of cylinders arranged horizontally and overlapping up and down. The output end of the upper cylinder is fixedly connected to the outer turning gripper 6, and the output end of the lower cylinder is fixedly connected to the lower cylinder. Through the two groups of cylinders, multi-stage displacement of the outer turning gripper 6 can be realized, and thus more delicate and complex flanging actions can be realized.
