[0027] The implementation principle of a hardware bending device that is easy to fix in the embodiment of the present application is: fix the assembly, place the hardware on the placement plate 9, and then start the cylinder 7 to push the return frame 6 to the right. During the pushing process, the gear B16 is acted upon by the tooth plate 17, so that the gear B16 drives the worm 15 and the gear A11 to rotate. The rotation of the gear A11 causes the bidirectional screw rod 10 to rotate, thereby causing the two moving blocks 12 to move toward the surface of the hardware until the front and back of the hardware are fixed, thereby preventing the hardware from being offset during the bending work.

[0028] At the same time, under the action of gear B16, the worm 15 rotates so that the worm wheel 18 drives the bevel gear B26 to rotate through the bevel gear A25, and then the bevel gear B26 rotates with the bevel gear D20 through the bevel gear C19, so that the small lead screw 21 rotates, and the threaded barrel 22 moves the sliding plate 23 downward, and cooperates with the placement plate 9 and the return frame 6 to fix the upper and lower surfaces of the hardware, thereby ensuring the stability of the hardware during bending work.

[0029] When facing hardware of different sizes, the three adjusting screws are rotated respectively so that the adjusting screws move with the abutment plates, thereby changing the distance between the abutment A13 and the abutment B24 and the surface of the hardware, so that when the cylinder 7 pushes the hardware to the working place, the abutment A13 and the abutment B24 can both abut against the surface of the hardware to fix the hardware, so that the device can adapt to the fixation of hardware of different sizes.

[0030] After the hardware is fixed, the motor is started, so that the movable screw rod 3 moves toward the surface of the hardware plate with the push plate 5 through the connecting plate 4 to bend the hardware plate.

[0031] When the device pushes the return frame 6 toward the work site through the cylinder 7, the limiting fixation of the hardware is gradually completed. After the hardware completes the bending work, the cylinder 7 brings the return frame 6 back to the initial position. At the same time, under the action of the tooth plate 17, the sliding plate 23 moves upward, and the two moving blocks 12 move away from each other, so that the device releases the clamping fixation of the hardware, which is convenient for directly taking out the hardware, thereby improving the convenience of the device.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
