[0005] Preferably, the frame is a rectangular frame, which is formed by the butting of two "L" shaped frames, and the two "L" shaped frames are detachably connected.

[0006] Preferably, positioning nuts are respectively arranged at the two connecting ends of the "L" shaped frame, and the positioning nuts are connected by a screw rod.

[0007] Preferably, the connecting rod is a telescopic connecting rod.

[0008] Preferably, the connecting rod includes two angle irons inserted together, and long holes are respectively arranged at corresponding positions of the angle irons and fixed by a bolt group.

[0009] Preferably, both ends of the connecting rod are detachably fixed on adjacent frames.

[0010] Preferably, positioning seats are respectively arranged at both ends of the connecting rod and fixed on the frame 1 by bolts.

[0011] Preferably, the top adjusting rod is a telescopic adjusting rod.

[0012] Preferably, the telescopic adjusting rod includes a sleeve and a core tube inserted in the sleeve, and long strip holes are respectively arranged on both sides of the sleeve and fixed in cooperation with a screw rod.

[0013] The present invention provides a multi-sided flange forming device, which can form products with more multi-sided flange edges at one time, and has the advantages of being easy to operate, high forming efficiency, high forming strength, and good product appearance quality.

DETAILED DESCRIPTION OF THE INVENTION

[0020] Next, with reference to the drawings, a specific embodiment of the present invention will be described in detail, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0021] As Figures 1-4 shown, a multi-sided flange forming device provided by an embodiment of the present invention includes a plurality of frames 1, the frames 1 are in conformity with the shape of the product flange, the plurality of frames 1 are sequentially distributed in the vertical direction, adjacent frames 1 are connected by a plurality of connecting rods 2, and a plurality of top adjusting rods 3 are connected to the topmost frame 1, and a cross bar 4 is connected to the top adjusting rods 3.

[0022] In order to make it detachable and convenient for use and storage, the frame 1 is a rectangular frame, which is formed by fitting two "L"-shaped frames 11, the two "L"-shaped frames 11 are detachably connected, positioning nuts 12 are respectively provided at the two connecting ends of the "L"-shaped frame 11, and the positioning nuts 12 are connected by a screw rod 13.

[0023] In order to adapt to products with different flange spacings, the connecting rod 2 is a telescopic connecting rod, and the number thereof is four. The connecting rod 2 includes two angle irons 21 inserted together. Long holes 22 are respectively provided at corresponding positions of the angle irons 21 and fixed by a bolt group 23, making it detachable, facilitating use and storage. The two ends of the connecting rod 2 are respectively detachably fixed to adjacent frames 1. Positioning seats 24 and bolts 25 are respectively provided at the two ends of the connecting rod 2 and fixed to the frame 1.

[0024] In order to match the height of the product, the top adjusting rod 3 is a telescopic adjusting rod. The telescopic adjusting rod includes a sleeve 31 and a core pipe 32 inserted into the sleeve 31. Long strip holes 33 are respectively provided on both sides of the sleeve 31 and fixed in cooperation with a screw rod 34.

[0025] The working principle or operation mode of the present invention: During use, it is used in cooperation with a mold 6. The mold 6 is a rectangular cylinder structure and serves to support the inner membrane. It is positioned above the mold 6 through a cross bar 4. After positioning, a laying operation is carried out, and several flanges are formed by laying through several frames 1. After the product is in a stable state, the forming device can be removed.
