[0044] When the bending machine is in use, one end of the glasses leg to be processed is clamped on the downward bending fixture 4, and the other end is bent downward by the downward bending mechanism 2 on the downward bending station to form a bending portion for hooking the ear, so that the glasses can be firmly worn on the ear; the conveying mechanism 6 then conveys the glasses leg that has been bent downward to the inward bending station, and the downward bending fixture 4 clamps the glasses leg, and the inward bending mechanism 3 bends it inward, so that the glasses leg has a certain inward bending arc, which prevents the glasses from sticking to the wearer's face when worn, thereby improving the comfort of wearing the glasses; the bending machine replaces manual bending processing, realizes automated production, improves production efficiency, and at the same time ensures the bending amplitude of the glasses leg, thereby improving the qualified rate of products.

[0045] The downward bending mechanism 2 includes a downward bending base 21 and two downward bending devices 22 arranged on the downward bending base 21; wherein the two downward bending devices 22 perform downward bending processing on the two temples of the eyeglass frame at the same time;

[0046] The downward bending device 22 includes a first mounting frame 221, a support arm 222 with one end rotatably disposed on the first mounting frame 221, a downward bending component 223, and a twisting drive component 224 for driving the support arm 222 to rotate (wherein the twisting drive component 224 is driven by an existing drive motor and is driven by a belt and a gear 3241);

[0047] The downward bending assembly 223 includes a swing arm 2231 whose lower end is rotatably arranged on the support arm 222, an upper bending wheel 2232, a lower bending wheel 2233 rotatably arranged on the support arm 222, and a downward bending driving assembly 2234 for driving the swing arm 2231 to swing (wherein the downward bending driving assembly 2234 is driven by an existing driving motor, and transmission is realized by cooperation between a belt, a gear 3241, and a cone wheel);

Driven by the bending wheel driving cylinder 226, the wheel 2232 moves toward the lower bending wheel 2233 and cooperates with the lower bending wheel 2233 to clamp the glasses leg to be bent downward; when the bending process is completed, the upper bending wheel 2232 is driven by the bending wheel driving cylinder 226 to move away from the lower bending wheel 2233 and separate from the lower bending wheel 2233, so that the glasses leg can be pulled out from between the upper bending wheel 2232 and the lower bending wheel 2233.

[0050] The first mounting frames 221 of the two downward bending devices 22 are both slidably arranged on the downward bending base 21, and the base is provided with a first driving assembly 23 for driving the two first mounting frames 221 to slide toward or away from each other (the first driving assembly 23 includes an existing driving motor, a lead screw and two screw sleeves respectively connected to the first mounting frames 221, wherein one end of the lead screw is connected to the output shaft of the driving motor, and the other end is threadedly connected to the screw sleeve, so as to realize driving the two first mounting frames 221 to move toward or away from each other); when the downward bending processing of the eyeglass feet is completed, the first driving assembly 23 drives the two first mounting frames 221 to move away from each other, so that the two eyeglass feet of the eyeglass frame are separated from the corresponding downward bending assembly 223; when the next eyeglass foot is sent to the downward bending station, the first driving assembly 23 drives the two first mounting frames 221 to move downward, so that the two eyeglass feet of the eyeglass frame can be placed on the corresponding downward bending assembly 223 respectively;

[0051] The downward bending base 21 is slidably arranged on the workbench 1, and a second driving assembly 24 is arranged on the workbench 1 to drive the downward bending base 21 to slide forward and backward (the second driving assembly 24 is driven by an existing driving motor and is transmitted by existing gears 3241, belts, screws and screw sleeves); when the downward bending process is completed, and after the first driving assembly 23 drives the two first mounting frames 221 to move in opposite directions, the second driving assembly 24 drives the base to move backward, so that the glasses frame that has completed the downward bending process is separated from the downward bending mechanism 2, so that the glasses frame that has completed the downward bending process can be transported to the inward bending station by the conveying mechanism 6.

[0052] The inward bending mechanism 3 includes an inward bending base 31 and two inward bending devices 32 arranged on the inward bending base 31; wherein the two inward bending devices 32 perform inward bending processing on the two temples of the eyeglass frame at the same time;

(When the clamping and bending driving assembly 3254 starts to pull the steel wire 32541, the resistance of the tension spring 3255 is greater than the return spring 32561, so that the clamping seat 3256 slides backward, thereby driving the second clamping roller 3252 to approach the first clamping roller 3251, so as to clamp the temple of the glasses. After clamping, the second clamping roller 3252 abuts against the temple of the glasses, so that the clamping seat 3256 cannot move in the sliding direction, leading to The clamping seat 3256 is in a stationary state, and the traction wire 32541 continues to pull to overcome the resistance of the tension spring 3255, driving the swinging member 3253 to swing around the rotating shaft). In this process, the reset spring 32561 is compressed, so that the second clamping roller 3252 moves toward the first clamping roller 3251 and clamps the eyeglass leg; the clamping and bending driving assembly 3254 then drives the swinging member 3253 to rotate around the rotating shaft, so that the bending roller 326 presses the outer wall of the eyeglass leg inward;

[0054] One end of the temple to be bent is clamped on the inward bending fixture, and the other end is placed on the clamping assembly 325; the clamping and bending drive assembly 3254 first moves the swinging member 3253 backward with the clamping seat, so that the second clamping roller 3252 moves toward the side of the first clamping roller 3251, and cooperates with the first clamping roller 3251 to clamp the temple to be bent; the clamping and bending drive assembly 3254 continues to drive, driving the swing arm to rotate around the rotating shaft, so that the bending roller 326 rotates with the swinging member 3253, squeezing the outer wall of the temple inward, so that the temple is bent inwardly with a certain arc, so that the temple is more suitable for the wearer's face shape, avoids the temple from sticking to the wearer's face, and improves the comfort of wearing glasses; the inward bending mechanism replaces the traditional manual bending operation, improves production efficiency, and at the same time improves the accuracy of the bending range to ensure the product qualification rate.
