Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution for an automatic feeding structure for a bending machine: an automatic feeding structure for a bending machine, including a processing table 1 and a bar stock 4. A material conveying mechanism 2 is arranged on the processing table 1 and is used for conveying the bar stock 4, and a discharging mechanism 3 is arranged on the processing table 1 and is used for discharging the bar stock 4. The material conveying mechanism 2 includes:

[0025] A conveying component 21, including a main frame 211 fixed to the rear end of the top of the processing table 1, and a lower plate 212 fixed to the top of the main frame 211;

[0026] The feeding assembly 22 includes a base 221 fixed to the middle of the top of the processing table 1, a ramp frame 222 fixed to the top of the base 221, a secondary frame 223 fixed to the top of the processing table 1 and located directly in front of the base 221, a ramp plate 224 fixed to the top of the secondary frame 223, a carriage 225 longitudinally slidably mounted above the rear end of the base 221, a ramp block 226 fixed to the top of the carriage 225, and a cylinder 227 mounted at the rear end of the base 221 for driving the carriage 225.

[0027] In this embodiment, when feeding is required, the output end of the cylinder 227 drives the carriage 225 to drive the ramp block 226 to move upward, so that the ramp block 226 pushes the frontmost bar stock 4 to rise until the bottom of the bar stock 4 is higher than the top of the ramp frame 222, so that the bar stock 4 can fall onto the ramp plate 224 through the ramp frame 222. And then, the output end of the cylinder 227 drives the carriage 225 to drive the ramp block 226 to move downward to reset under the lower plate 212.

[0028] Specifically, the conveying assembly 21 further includes side plates 213 fixed to both ends of the lower plate 212, a middle plate 214 fixed between the middle parts of the two side plates 213, an upper plate 215 fixed between the upper parts of the two side plates 213, a front baffle 216 fixed to the front end of the upper plate 215, a rear baffle 217 fixed above the rear end of the base 221, and an upper baffle 218 fixed between the upper ends of the two side plates 213.

[0029] In this embodiment, the bar stock 4 can be fed onto the upper plate 215 manually or by a conveyor belt through the space between the upper baffle 218 and the upper end of the rear baffle 217. The bar stock 4 then continues to roll on the upper plate 215 and collides with the front baffle 216 and then rolls onto the side plates 213, and then continues to roll on the side plates 213 and collides with the rear baffle 217 and then rolls onto the lower plate 212 until the bar stock 4 rolls to the frontmost part of the lower plate 212 and is blocked by the ramp frame 222 to restrict its further rolling.

[0030] Specifically, the feeding assembly 22 further includes a limit frame 228 fixed above the front end of the secondary frame 223, and the limit frame 228 is located below the front end of the ramp plate 224.

[0031] In this embodiment, the bar stock 4 that falls onto the ramp plate 224 finally rolls into the limit frame 228 for subsequent operation by the discharging mechanism 3.

[0032] Specifically, the discharging mechanism 3 includes a vertical frame 31 fixed to the front end of the top of the processing table 1, a guide rail 32 fixed to the upper end of the vertical frame 31, a slider 33 slidably mounted on the guide rail 32, a push head 34 mounted at the rear end of the slider 33, a chute frame 35 fixed to the front end of the slider 33, a mounting frame 36 fixed to the top of the processing table 1, a servo motor 37 mounted on the mounting frame 36, a crank 38 fixed to the output end of the servo motor 37, and a guide wheel 39 rotatably mounted at the other end of the crank 38, and the guide wheel 39 is located inside the chute frame 35.

[0033] In this embodiment, when the bar stock 4 falls into the limit frame 228, the output end of the servo motor 37 drives the crank 38 to rotate clockwise. The crank 38 drives the slider 33 to slide along the guide rail 32 in cooperation with the chute frame 35, and the guide wheel 39 moves along the inside of the chute frame 35. At the same time, the slider 33 drives the push head 34 to push the bar stock 4 out of the limit frame 228 and send it to a bending machine for subsequent processing. And before the next bar stock 4 enters the limit frame 228, the push head 34 is controlled to reset by the output end of the mounting frame 36 rotating counterclockwise.

[0034] The working principle and usage process of the present utility model: First, the bar stock 4 can be sent onto the upper plate 215 manually or through a conveyor belt between the upper baffle 218 and the upper end of the rear baffle 217. The bar stock 4 then continues to roll down from the upper plate 215 and collides with the front baffle 216 and then rolls onto the side plate 213, and then continues to roll down from the side plate 213 and collides with the rear baffle 217 and then rolls onto the lower plate 212 until the bar stock 4 rolls to the forefront of the lower plate 212 and is blocked by the ramp frame 222, restricting its continued rolling.

[0035] Then, when feeding is required, the output end of the air cylinder 227 drives the carriage 225 to drive the ramp block 226 to move upward, so that the ramp block 226 pushes the foremost bar stock 4 to rise until the bottom of the bar stock 4 is higher than the top of the ramp frame 222, so that the bar stock 4 can fall onto the ramp plate 224 through the ramp frame 222. And then, the output end of the air cylinder 227 drives the carriage 225 to drive the ramp block 226 to move downward to the lower part of the lower plate 212 for resetting.

[0036] Finally, the bar stock 4 that falls onto the ramp plate 224 finally rolls into the limit frame 228. The output end of the servo motor 37 drives the crank 38 to rotate clockwise. The crank 38 drives the slider 33 to slide along the guide rail 32 in cooperation with the chute frame 35, and the guide wheel 39 moves along the inside of the chute frame 35. At the same time, the slider 33 drives the push head 34 to push the bar stock 4 out of the limit frame 228 and send it to a bending machine for subsequent processing. And before the next bar stock 4 enters the limit frame 228, the push head 34 is controlled to reset by the output end of the mounting frame 36 rotating counterclockwise.
