[0020] See also Figure 1-Figure 5 , an elbow bending device, comprising a processing table 1, a feeding mechanism 2 and a bending mechanism 3 are arranged on the surface of the processing table 1;

[0021] The feeding mechanism 2 enables the elbow to be fed automatically, and the bending mechanism 3 can bend the elbow.

[0022] The feeding mechanism 2 includes a mounting frame 201, two rubber pads 202 are fixed on the top of the mounting frame 201, a collection shell 203 is fixed on the top of the rubber pad 202, a vibration motor 204 is fixed on the surface of the collection shell 203, two unloading plates 205 are fixed on the inner wall of the collection shell 203, the unloading plates 205 are wedge-shaped, a discharge port 206 is provided at the bottom of the collection shell 203, and the width of the discharge port 206 is greater than or equal to the diameter of the elbow, three support plates 207 are fixed on the top of the processing table 1, a rodless cylinder 208 is fixed on the top of the processing table 1, a push block 209 is fixed on the slide on the surface of the rodless cylinder 208, a side plate 210 is fixed on the top of the processing table 1, a connecting rod 216 is rotatably connected to the surface of the side plate 210, a feeding tray 217 is fixed on the surface of the connecting rod 216, four material receiving grooves 218 are provided on the surface of the feeding tray 217, and a through groove used in conjunction with the feeding tray 217 is provided on the surface of the processing table 1;

[0023] The elbows are stored in the aggregate shell 203, and the elbows can be accumulated along the inclined surface of the discharge plate 205 toward the top of the discharge port 206, and the elbows at the bottom can pass through the discharge port 206 and fall into the receiving trough 218. At the same time, the vibration motor 204 can be in a working state, so that the aggregate shell 203 can produce a small vibration, and the rubber pad 202 can be compressed and deformed to achieve vibration buffering. The vibration of the aggregate shell 203 allows the elbows accumulated inside the discharge plate 205 to move relative to each other, avoiding the accumulation and jamming of multiple elbows due to the friction of mutual contact, thereby blocking the discharge port 206, ensuring the normal discharge of materials, and the feeding tray 21 7 can drive the elbow to rotate ninety degrees, so that the elbow can be conveyed to the surface of the support plate 207, and during the rotation of the feeding tray 217, the surface of the feeding tray 217 will block the bottom of the discharge port 206 to prevent the elbow from unloading by itself. After the feeding tray 217 rotates, the empty receiving groove 218 on the top of the feeding tray 217 will be able to receive a single elbow again to achieve continuous feeding. When the elbow is placed on the surface of the support plate 207, starting the rodless cylinder 208 can make the push block 209 push the elbow to move toward the feeding mechanism 2, so that the elbow can be conveyed between the bending wheel 304 and the positioning wheel 303, so as to facilitate the subsequent bending process, thereby realizing automatic feeding of the elbow.

[0024] Furthermore, the bending mechanism 3 includes a second motor 301, which is fixed to the bottom of the processing table 1. The output shaft of the second motor 301 passes through the processing table 1 and is fixed with a U-shaped frame 302. The surface of the U-shaped frame 302 is rotatably connected with a positioning wheel 303 and a bending wheel 304.

[0025] When the elbow is transported to between the bending wheel 304 and the positioning wheel 303 by the push block 209, the second motor 301 drives the U-shaped frame 302 to rotate. At this time, the elbow can be pushed and bent by the bending wheel 304 on the surface of the U-shaped frame 302 to complete the bending process. After the bending is completed, the second motor 301 drives the U-shaped frame 302 to reset. At this time, the continued push of the push block 209 will be able to push out the bent elbow normally, realizing automatic unloading of the elbow, and then the rodless cylinder 208 drives the push block 209 to reset, and the feeding tray 217 rotates, so that the next elbow continues to be placed on the surface of the support plate 207.

[0026] Further, a first motor 211 is fixed on the surface of the side plate 210, and an output shaft of the first motor 211 passes through the side plate 210 and is fixed with a driving wheel 212, a curved inner concave portion is provided on the surface of the driving wheel 212, a pin rod 213 is fixed on the surface of the driving wheel 212, a driven wheel 214 is fixed on the surface of the connecting rod 216, and four slots 215 are provided on the surface of the driven wheel 214, and the driven wheel 214 is slidably connected to the surface of the driving wheel 212;

[0027] When the first motor 211 is started, it can drive the driving wheel 212 to rotate. The driving wheel 212 can fit with the surface of the driven wheel 214, so that the driven wheel 214 can be limited. When the driving wheel 212 rotates until the pin rod 213 enters the slot 215, the driven wheel 214 will be driven to rotate by the pin rod 213. At this time, the driven wheel 214 will rotate in the arc-shaped concave part on the surface of the driving wheel 212, so that the driven wheel 214 can drive the connecting rod 216 to rotate ninety degrees, thereby achieving the effect of driving the elbow to rotate and convey through the feeding tray 217.

[0028] Furthermore, a positioning frame 305 is provided on one side of the U-shaped frame 302, and the positioning frame 305 is fixed to the top of the processing table 1. A clamping cylinder 306 is fixed to the top of the positioning frame 305, and one end of the clamping cylinder 306 passes through the positioning frame 305 and is fixed with a clamp 307;

[0029] When the elbow is pushed into between the bending wheel 304 and the positioning wheel 303, the clamping cylinder 306 is activated to drive the clamp 307 to move downward, so that the clamp 307 can clamp and fix the elbow to prevent the elbow from deflecting and moving during the bending process. The clamp 307 can be some commonly used mechanical clamps.

[0030] Furthermore, the bottom height of the push block 209 is higher than the top height of the support plate 207, and the top of the support plate 207 is arranged in a V-shaped structure;

[0031] The setting of the push block 209 ensures that the push block 209 will not collide with the support plate 207 when moving, and the setting of the shape of the support plate 207 enables the elbow to more easily obtain a limiting effect through the V-shaped structure.

[0032] Furthermore, the second motor 301 is a servo motor, and a brake device is installed at the tail of the second motor 301;

[0033] The servo motor can accurately control the rotation angle of its output shaft, so that the bending angle of the elbow can be more accurate. The setting of the brake device can achieve a self-locking effect on the output shaft when the second motor 301 stops running, thereby preventing the U-shaped frame 302 from rotating on its own.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
