[0036] Combination Figures 1 to 7 As shown, the utility model discloses a bending and pressing device, comprising:

[0037] Working platform 1,

[0038] The positioning mechanism comprises a profiling mold 2, which is arranged on the working platform 1 and is used to place the pre-installed metal support frame 6 and the plastic inner frame 7, wherein the metal support frame 6 is at the bottom of the plastic inner frame 7; the plastic inner frame 7 has a connecting slot 71, and the metal support frame 6 has a pin 61 which penetrates the connecting slot 71 and protrudes vertically upward;

[0039] The side bending mechanism 3 includes a bending column 31 and a first driving device 32 for driving the bending column 31 to reciprocate in the horizontal direction, wherein the bending column 31 is arranged outside the profiling die 2 to bend the pin 61 so that the pin 61 is arranged obliquely;

[0040] The pressing mechanism 4 includes a pressing fixed block 41, a pressing bending component 42, and a second driving device 43 for synchronously driving the pressing fixed block 41 and the pressing bending component 42 to reciprocate in the vertical direction. The pressing bending component 42 includes a pressing column 44 and a third driving device 45 for driving the pressing column 44 to reciprocate in the vertical direction. The pressing column 44 is arranged above the pin 61 to press down the tilted pin 61 to complete the connection between the metal support frame 6 and the plastic inner frame 7.

[0041] Compared with the prior art, the utility model discloses a bending and pressing device, which innovatively arranges a side bending mechanism 3 and a pressing mechanism 4 to perform secondary bending on the pins 61 to complete the connection between the metal support frame 6 and the plastic inner frame 7, with high production efficiency and high product connection quality.

[0042] Specifically, the staff places the pre-installed metal support frame 6 and plastic inner frame 7 on the profiling mold 2, and then the equipment starts the automatic bending action. First, the second drive device 43 drives the downward pressing fixing block 41 and the downward pressing bending component 42 to move downward, so that the downward pressing fixing block 41 fixes the metal support frame 6 and the plastic inner frame 7, and then the first drive device 32 drives the bending column 31 to bend the pin 61 in the horizontal direction, so that the pin 61 is in an inclined state at a certain angle; finally, the third drive device 45 drives the pressing column 44 to press down the inclined pin 61, thereby completing the connection work between the metal support frame 6 and the plastic inner frame 7.

[0043] In one embodiment, one end of the bending column 31 acting on the pin 61 is a first inclined surface. After the bending column 31 bends the pin 61, the first inclined surface abuts against the surface of the pin 61, so that the inclination angle of the pin 61 in the first bending is the same as the inclination angle of the first inclined surface, thereby limiting the inclination angle of the pin 61 after the first bending, so that the pin 61 after the first bending is located just below the pressing column 44.

[0044] In one embodiment, one end of the pressing column 44 acting on the pin 61 is a second inclined surface. When the pressing column 44 presses down the inclined pin 61, the second inclined surface abuts against the surface of the pin 61, so that the inclination angle of the pin 61 after the second bending is the same as the inclination angle of the second inclined surface, thereby limiting the inclination angle of the pin 61 after the second bending to ensure that the metal support frame 6 is firmly connected to the second piece.

[0045] In one embodiment, the first driving device 32 is a pneumatic cylinder, a hydraulic cylinder, an electric cylinder or a motor.

[0046] In one embodiment, the second driving device 43 is a pneumatic cylinder, a hydraulic cylinder, an electric cylinder or a motor.

[0047] In one embodiment, the third driving device 45 is a pneumatic cylinder, a hydraulic cylinder, an electric cylinder or a motor.

[0048] If the positions of the bending column 31, the pressing column 44 and the pressing fixed block 41 do not require very high moving position accuracy, the first, second and third driving devices are preferably cylinders and hydraulic cylinders; if the moving positions of the bending column 31, the pressing column 44 and the pressing fixed block 41 require very high accuracy, the first, second and third driving devices are preferably electric cylinders and motors; if the first, second and third driving devices are motors, they can be used in conjunction with transmission parts such as screws, gear racks, etc.

[0049] In one embodiment, the bending and pressing equipment also includes a limit column 5, which is arranged on the working platform 1 in the vertical direction; the pressing mechanism 4 has a positioning plate 46, and the pressing fixed block 41 is connected to the positioning plate 46 and is arranged below the positioning plate 46, and the pressing column 44 is movably passed through the positioning plate 46; when the third driving device 45 drives the pressing column 44 to press down, the positioning plate 46 and the limit column 5 are abutted to limit the lowest position of the pressing fixed block 41 to avoid the metal support frame 6 and the plastic inner frame 7 from being sunken due to excessive pressing of the pressing fixed block 41, thereby effectively ensuring the yield rate of the metal support frame 6 and the plastic inner frame 7.

[0050] Preferably, the pressing and fixing block 41 is made of a hard non-metal material, such as nylon, bakelite, polyoxymethylene, etc., to avoid damaging the plastic inner frame 7 in contact with the pressing and fixing block 41 .

[0051] In one embodiment, there are two profiling dies 2, which are mirror-imaged on the left and right; there are two side bending mechanisms 3, which are respectively arranged on one side of the two profiling dies 2; there are two pressing mechanisms 4, which are respectively arranged above the two profiling dies 2; that is, the bending and pressing device of the utility model has a double station, which can press two products at the same time, effectively improving production efficiency.

[0052] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the claims of the present invention and the scope of equivalent technologies, the present invention is also intended to include these changes and modifications.
