[0037] The technical scheme of the utility model will be described in detail below with specific examples. The following specific examples can be combined or replaced according to actual conditions, and the same or similar concepts or processes may not be described in some examples.

[0038] As shown in Figures 1 to 6 The utility model provides a kind of feeding device of automatic round rolling whole type flanging forming machine, it is suitable for automatic round rolling whole type flanging forming machine, for the feeding of steel band or strip composite material and the like material, feeding device includes base 10 and is set on base 10 feeding frame 200, pressing piece 201 and feeding piece 202, feeding frame 200 includes feeding end 203 and discharge end 204, feeding piece 202 reciprocates under the action of external force in the feeding end 203 and discharge end 204 of feeding frame 200 to tow material is transported by feeding end 203 towards discharge end 204, pressing piece 201 is fixed in the discharge end 204 of feeding frame 200 and is used to fix the material transported to discharge end 204 by feeding piece 202, feeding frame 200 is equipped with the guide material assembly that the circumferential position of material is limited in the feeding direction and can guide material to be transported in the feeding direction.

[0039] By setting guide material assembly on feeding frame 200, the circumferential position of material can be limited in the feeding direction, and material can be effectively guided to be transported along predetermined path, so that material can more accurately reach the position of next station, as far as possible to solve the deformation and displacement problem caused by material suspension in prior art, to facilitate flexible material transport, so as to ensure the stability of material as far as possible in the process of transport.

[0040] Specifically, the material guiding assembly includes a material guiding channel 205 connected with the feeding end 203 and the discharging end 204, which can more accurately limit and guide the circumferential position of the material, so that the material can maintain the correct posture and path as much as possible during the conveying process, and the unexpected deformation of the flexible material due to its own gravity or external interference can be effectively reduced, thereby improving the position accuracy of the material when reaching the next station. The feeding rack 200 is provided with an avoiding opening 206 for the feeding member 202 to extend into the material guiding channel 205 to pull the material, which provides sufficient space for the feeding member 202 to extend into the material guiding channel 205 to pull the material, while avoiding collision or interference between the feeding member 202 and other parts, thereby improving the safety and reliability of the operation.

[0041] In the embodiment, the material enters the material guiding channel 205 through the feeding end 203 under the action of an external force, the feeding rack 200 is provided with two material guiding members 207 with grooves 214, the grooves 214 of the two material guiding members 207 are oppositely arranged to form the material guiding channel 205, and the length of one of the material guiding members 207 is smaller than that of the other material guiding member 207 to form the avoiding opening 206, which provides sufficient space for the feeding member 202 to extend into the material guiding channel 205 to pull the material, while preventing the feeding member 202 from colliding or interfering with other parts, thereby improving the safety and reliability of the operation, and also allowing the material to always be in at least one groove 214 to always be guided and limited, thereby reducing the deformation of the material and making the feeding more accurate.

[0042] To further make the conveying direction of the material more accurate, the feeding rack 200 is provided with two guide wheels 208 near the feeding end 203, the guide wheels 208 and the avoiding opening 206 are located on opposite sides of the material guiding channel 205, the guide wheels 208 can more accurately control the position of the material to ensure that it maintains a relatively accurate posture when entering the material guiding channel 205, thereby reducing the displacement or distortion of the material, and the guide wheels 208 can also move along the material guiding channel 205 to push the material to expose the avoiding opening 206, thereby facilitating the feeding member 202 to pull the material.

[0043] For ease of understanding, in the present application, the feeding direction is in the left-right direction of the horizontal plane, the shorter material guiding member 207 is located at the rear side of the longer material guiding member 207, the avoiding opening 206 is located at the rear side of the material guiding channel 205, and the guide wheels 208 are located at the front side of the material guiding channel 205, and the guide wheels 208 move backward to push the material to expose the avoiding opening 206.

[0044] Specifically, the material guiding channel 205 located on one side of the guide wheels 208 is provided with a notch 209, the feeding rack 200 is provided with a mounting plate 210, one end of the mounting plate 210 is rotationally connected with the feeding rack 200, and the guide wheels 208 are mounted on the other end of the mounting plate 210, so that the guide wheels 208 can be moved backward by rotating the mounting plate 210 to push the material.

[0045] Due to the different thickness and width of different materials, the material guiding member 207 can be relatively moved to adjust the width of the material guiding channel 205. Specifically, the material guiding member 207 can be moved forward and backward, and the adjustable width of the material guiding channel 205 enables the feeding device to adapt to materials of different thickness and width, so that each kind of material can be guided and conveyed under better conditions as much as possible, reducing the positional deviation and deformation problem caused by size mismatch, greatly expanding the application range of the feeding device, and being suitable for more extensive production needs. In addition, it is not necessary to replace the material guiding member 207 or re-set the entire feeding device, thereby improving the flexibility and response speed of the production line.

[0046] Due to the fact that part of the material is flexible material, it is more likely to deform and be stuck. The material guiding member 207 includes two oppositely arranged material guiding portions 211, specifically two oppositely arranged material guiding portions 211, which cooperate to form a groove 214. The two material guiding portions 211 are detachably connected. When the material guiding channel 205 is blocked by material, the material guiding portion 211 can be quickly removed to quickly remove the blockage, thereby reducing downtime and enabling the production line to resume normal operation as soon as possible. In addition, during the long-term conveying of the material, the inner wall of the material guiding channel 205 is easily rubbed by the material, which can cause burrs, thereby increasing the resistance to the material and affecting the conveying of the material. The detachable connection of the two material guiding portions 211 also facilitates the cleaning and polishing of the material guiding channel 205 after long-term material conveying, thereby maintaining the smoothness of the material guiding channel 205 and reducing the frictional resistance to the material.

[0047] In the embodiment, the lower material guiding portion 211 of the two material guiding members 207 is integrally arranged, and the lower material guiding portion 211 is flat and provided with a positioning hole 212. The upper material guiding portion 211 of the two material guiding members 207 is separately arranged and has a strip-shaped hole 213. The two material guiding portions 211 are fixed by a nut after a bolt passes through the strip-shaped hole 213 and the positioning hole 212. During use, the two material guiding portions 211 can be moved forward and backward, and the position of the bolt in the strip-shaped hole 213 can be adjusted to adjust the width of the material guiding channel 205.

[0048] Further, at least one side of the avoiding opening 206 is provided with a limiting plate 229 for pressing the material. The limiting plate 229 and the avoiding opening 206 are in sliding connection, and the limiting plate 229 is provided with an avoiding hole 230 for avoiding the feeding member 202. The feeding member 202 extends into the avoiding hole 230 to press the material, and the feeding member 202 drags the material to be conveyed from the feeding end 203 to the discharging end 204 while dragging the limiting plate 229 to move. The limiting plate 229 is in sliding connection with the avoiding opening 206 and moves together with the feeding member 202. The limiting plate 229 can additionally limit the circumferential position of the material during conveying, so as to ensure that the material maintains the correct posture during conveying and reduces the risk of transverse displacement or distortion.

[0049] The movement stability of the feeding member 202 also affects the material conveying, in order to further improve the stability in the conveying process, the base 10 is provided with a feeding driver 215 and a feeding track 216 extending in the feeding direction, the feeding member 202 is connected to the feeding track 216, and the feeding driver 215 is used to drive the feeding member 202 to reciprocate along the feeding track 216. The feeding track 216 provides a stable running path for the feeding member 202, reduces the unstable problem of material conveying caused by vibration or deviation, and further guarantees the linearity and stability of the material in the conveying process.

[0050] It should be noted that the feeding driver 215 can be a moving screw pair driven by a driving motor. The motor drive can provide stable power output, ensure the consistency and repeatability of each feeding action as much as possible, and meet mass production and precision machining.

[0051] Since different production lines of the automatic round rolling and shaping flanging forming machine have different material conveying positions, therefore, in the utility model, the base 10 is provided with a longitudinal slide rail 217 and a transverse slide rail 218 slidably connected to the longitudinal slide rail 217, the feeding frame 200 is connected to the transverse slide rail 218, the transverse slide rail 218 is provided with a transverse driver 219 for driving the feeding member 202 to slide transversely on the transverse slide rail 218, and the longitudinal slide rail 217 is provided with a longitudinal driver 220 for driving the transverse slide rail 218 to slide longitudinally on the longitudinal slide rail 217.

[0052] It should be noted that the longitudinal driver 220 and the transverse driver 219 can be a moving screw pair driven by hand. A rotating handle is arranged on the screw rod.

[0054] Specifically, the first clamping piece 223 is slidingly connected to the mounting seat 221, the second clamping piece 224 is fixed to the mounting seat 221, the mounting seat 221 is provided with a first connecting rod 225, a second connecting rod 226, a third connecting rod 227 and a fourth connecting rod 228, the first end of the first connecting rod 225 is hinged to the mounting seat 221, the tail end of the first connecting rod 225 and the first end of the second connecting rod 226 are simultaneously hinged to the output end of the clamping driver 222, the first end of the third connecting rod 227 and the tail end of the fourth connecting rod 228 are both hinged to the tail end of the second connecting rod 226, the tail end of the third connecting rod 227 is hinged to the mounting seat 221, and the first segment of the fourth connecting rod 228 is hinged to the first clamping piece 223. The design of the four connecting rods makes the movement of the first clamping piece 223 more stable, reduces the vibration or shaking of the material caused by direct force, and improves the reliability of the clamping process.

[0055] It should be noted that the first clamping piece 223 is above the second clamping piece 224, the first clamping piece 223 moves up and down to clamp the material, the first clamping piece 223 and the second clamping piece 224 can be clamping blocks, and the clamping driver 222 can be a pneumatic cylinder.
