Description

Technical Field

[0001] This invention relates to the field of pipe bending machine technology, and in particular to a pipe bending machine device with a cutting function. Background Technology

[0002] In the fields of machinery manufacturing, building pipelines, and automotive parts, pipe bending machines are key equipment for bending pipes. They bend metal pipes and plastic pipes at preset angles through the bending die mechanism to meet the installation requirements of different working conditions. Although there are existing technologies that integrate cutting functions into pipe bending machines in an attempt to solve the efficiency problem of traditional step-by-step processing, there are still many technical limitations in practical applications.

[0003] Regarding the coordination between cutting and clamping, the clamping and cutting actions of existing equipment are mostly controlled independently, lacking a precise linkage mechanism. If the clamping is not fully stable at the start of cutting, it can easily lead to pipe displacement. After cutting, the timing of the clamping component's reset does not match the rhythm of the cutting component's withdrawal, which may cause secondary damage to the cut. In addition, the problem of unloading the cut pipe is prominent. When cutting short pipes, because the cut pipes are short, they cannot move away from the pipe bending machine under the action of gravity, causing the cut pipes to hang on the clamping mechanism, requiring manual cleaning, which seriously affects the efficiency of continuous processing.

Detailed Implementation

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0039] Reference Figures 1-4 and Figure 11This is the first embodiment of the present invention. This embodiment provides a pipe bending machine device with cutting function. The pipe bending machine device with cutting function includes a main body component 1, including a pipe bending machine body 11. A head bending die mechanism 12 is provided on one side of the pipe bending machine body 11. The pipe bending machine body 11 and the head bending die mechanism 12 are existing technologies. The pipe bending machine body 11 can drive the head bending die mechanism 12 to bend the pipe. Those skilled in the art should know its working principle clearly, so it will not be described in detail here. A vertical plate 13 is fixed on the head bending die mechanism 12. A cutting component 14 is provided on the vertical plate 13. The cutting component 14 is used to cut the bent pipe. A protective cover 15 is fixed on one side of the vertical plate 13. The protective cover 15 is used to protect the transmission components of the cutting component 14.

[0040] Clamping assembly 2, disposed on upright plate 13, includes clamping member 21 disposed on the surface of upright plate 13, and slide rails 211 fixed to the surface of upright plate 13. There are three slide rails 211, two of which have lifting platforms 212 slidably connected to their surfaces. The surfaces of slide rails 211 are coated with lubricating grease to reduce friction. A support shaft 213 is fixed to the surface of the lifting platform 212. Two swing rods 214 are rotatably connected to the surface of the support shaft 213. A support shell 215 is fixed to the end of the swing rod 214, and a clamping body 2 slides inside the support shell 215. 16. Two clamping plates 217 are fixed at the end of the clamping body 216. The clamping plates 217 can support clamping of pipes of different diameters. A first spring 218 is fixed inside the other end of the clamping body 216. The other end of the first spring 218 is fixed to the inner wall of the support shell 215. The first spring 218 is currently in the normal state. A second spring 219 is fixed on the surface of the swing rod 214. A support block 2110 is fixed on the other end of the second spring 219. The second spring 219 is currently in the stretched state. The support block 2110 is fixed to the surface of the lifting platform 212.

[0041] When the two support shells 215 rotate around the support shaft 213 and move closer to each other, the two clamping bodies 216 inside them can move closer to each other, thereby allowing the four clamping plates 217 to clamp and fix the pipe fitting.

[0042] When the clamping body 216 clamps the pipe fitting, it can compress the first spring 218, thereby providing clamping force to the clamping body 216.

[0043] Since the swing angle of the swing arm 214 is constant, the movement trajectory of the support shell 215 is constant each time it is clamped. When clamping a pipe with a larger diameter, the first spring 218 is compressed to a greater extent, which makes the clamping force of the clamping body 216 on the pipe greater, so as to match the clamping requirements of the larger diameter pipe with a greater weight. Example 2

[0044] Reference Figure 3 and Figures 9-14 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0045] Specifically, the clamping assembly 2 also includes a pusher 22 disposed in the clamping body 216, including a power storage rod 221 that slides in the clamping body 216, a third spring 222 fixed on one side of the power storage rod 221, the third spring 222 is currently in a normal state, the other end of the third spring 222 is fixed to the inner wall of the clamping body 216, a support column 223 is rotatably connected inside the power storage rod 221, and a push wheel 224 is fixed on the surface of the support column 223.

[0046] When the clamping body 216 clamps the pipe, the push wheel 224 at the end of the accumulator 221 first contacts the pipe. Under the compression of the pipe, the push wheel 224 drives the accumulator 221 to slide into the clamping body 216, thereby compressing the third spring 222.

[0047] When the clamp is released, the cutting pipe is moved by rotating the push wheel 224, thereby moving the cutting pipe away from the pipe bending machine. The surface of the push wheel 224 is made of rubber material, which can increase the friction with the pipe.

[0048] The elastic coefficient of the third spring 222 is much smaller than that of the first spring 218. The first spring 218 only undergoes slight deformation after the energy storage rod 221 is pressed into the clamping body 216.

[0049] Specifically, the pusher 22 also includes a first toothed ring 225 fixed to the surface of the pusher wheel 224. The first toothed ring 225 is used to drive the pusher wheel 224 to rotate. A support rod 226 is fixed inside the power storage rod 221. A rotating sleeve 227 is rotatably connected to the surface of the support rod 226. A coil spring 228 is fixed to the surface of the rotating sleeve 227. The other end of the coil spring 228 is fixed to the inner wall of the power storage rod 221. The coil spring 228 is currently in a tightened state. The coil spring 228 is existing technology. Those skilled in the art should know its working principle and usage method. It will not be described in detail here. A take-up wheel 229 is fixed to the surface of the rotating sleeve 227. A cable 2210 is wound around the surface of the take-up wheel 229. A guide post 2211 is fixed to the other end of the cable 2210. The guide post 2211 is fixed to the inner wall of the clamping body 216.

[0050] When the power storage rod 221 moves into the clamping body 216, the elastic force of the coil spring 228 is released. At this time, the coil spring 228 drives the rotating sleeve 227 to rotate, thereby causing the rotating sleeve 227 to drive the winding wheel 229 to rotate, so that the winding wheel 229 can wind up the cable 2210.

[0051] When the power storage rod 221 moves out of the clamping body 216 under the push of the third spring 222, the cable 2210 can drive the winding wheel 229 to rotate, thereby causing the winding wheel 229 to drive the rotating sleeve 227 to rotate.

[0052] Specifically, the pusher 22 also includes a rotating wheel 2212 fixed to the surface of the rotating sleeve 227. A retaining plate 2213 is rotatably connected inside the rotating wheel 2212. A fourth spring 2214 is fixed to one side of the retaining plate 2213. The fourth spring 2214 is currently in a normal state. The other end of the fourth spring 2214 is fixed to the inner wall of the rotating wheel 2212. A second toothed ring 2215 is rotatably connected to the surface of the rotating wheel 2212. A groove 2215-1 is opened on the inner wall of the second toothed ring 2215. There are multiple grooves 2215-1. The retaining plate 2213 can be engaged in the groove 2215-1. The second toothed ring 2215 and the first toothed ring 225 mesh.

[0053] When the power storage rod 221 moves into the clamping body 216, the coil spring 228 can drive the rotating sleeve 227 to rotate, thereby causing the rotating sleeve 227 to drive the rotating wheel 2212 to rotate. At this time, the rotating wheel 2212 can drive the clamping plate 2213 to slide across the surface of the clamping slot 2215-1, and cannot drive the second toothed ring 2215 to rotate.

[0054] When the accumulator rod 221 moves out of the clamping body 216 under the push of the third spring 222, the winding wheel 229 drives the rotating sleeve 227 to rotate, so that the rotating sleeve 227 drives the rotating wheel 2212 to rotate in another direction. At this time, the rotating wheel 2212 can drive the second toothed ring 2215 to rotate through the card plate 2213 that is engaged in the card slot 2215-1, so that the second toothed ring 2215 drives the first toothed ring 225 to rotate, so that the first toothed ring 225 drives the push wheel 224 to rotate, so that the push wheel 224 drives the cut pipe away from the pipe bending machine body 11, preventing the cut pipe from getting caught on the clamping part 21.

[0055] Specifically, the clamping assembly 2 also includes a guide 23 disposed on the swing arm 214, including a rotating column 231 rotatably connected to the swing arm 214, a support sleeve 232 rotatably connected to the surface of the rotating column 231, a sliding sleeve 233 slidably disposed on the surface of the rotating column 231, a fifth spring 234 fixed on one side of the support sleeve 232, the fifth spring 234 is currently in a compressed state, the other end of the fifth spring 234 is fixed to one side of the sliding sleeve 233, a sliding groove 212-1 is provided on the surface of the lifting platform 212, the support sleeve 232 rolls in the sliding groove 212-1, a guide groove 13-1 and a reset groove 13-2 are provided on the surface of the upright plate 13, and the sliding sleeve 233 can slide in the guide groove 13-1 and the reset groove 13-2.

[0056] When the lifting platform 212 moves upward, it can drive the sliding sleeve 233 to slide in the guide groove 13-1, so that the guide groove 13-1 squeezes the sliding sleeve 233, thereby driving the swing rod 214 to swing, thereby driving the two support shells 215 to move closer to each other. When the sliding sleeve 233 moves to the end of the guide groove 13-1, under the push of the fifth spring 234, the sliding sleeve 233 falls into the reset groove 13-2.

[0057] When the lifting platform 212 moves downward, the sliding sleeve 233 slides in the reset groove 13-2. When the sliding sleeve 233 slides to the other end of the reset groove 13-2, under the reset pull of the second spring 219, it can drive the swing rod 214 to swing, so that the rotating column 231 drives the sliding sleeve 233 to slide into the guide groove 13-1. As the lifting platform 212 continues to move downward, it drives the sliding sleeve 233 to reset to the starting position. Example 3

[0058] Reference Figures 1-14 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0059] Specifically, the clamping assembly 2 also includes a drive component 24 disposed on one side of the upright plate 13, including a power motor 241 fixed to one side of the upright plate 13, a lead screw 242 fixed to the output end of the power motor 241, a movable seat 243 disposed on one side of the upright plate 13, the lead screw 242 being rotatably connected to the movable seat 243 by a thread, and a slide rail 211 sliding inside the movable seat 243, the slide rail 211 being fixed to one side of the upright plate 13, and the movable seat 243 being able to move stably up and down by the support of the slide rail 211.

[0060] Starting the power motor 241 will drive the lead screw 242 to rotate, thereby causing the lead screw 242 to drive the moving seat 243 to move up and down.

[0061] Specifically, the drive unit 24 also includes a connector 244 fixed to one side of the lifting platform 212. A sixth spring 245 is fixed to one side of the connector 244. The sixth spring 245 is currently in a stretched state. A positioning block 246 is fixed to the other end of the sixth spring 245. The positioning block 246 is fixed to one side of the upright plate 13.

[0062] After the lifting platform 212 rises, the pulling force of the sixth spring 245 can drive the lifting platform 212 to move downward to reset.

[0063] Specifically, the driving component 24 also includes an insert block 247 that slides within the connecting body 244. A pressing column 248 is fixed to one side of the insert block 247, and a support wheel 249 is rotatably connected to the other end of the pressing column 248. The support wheel 249 rolls on the surface of the slide rail 211. A seventh spring 2410 is fixed to one side of the insert block 247. The seventh spring 2410 is in a compressed state, and the other end of the seventh spring 2410 is fixed to the inner wall of the connecting body 244. A slot 211-1 is provided on the surface of the slide rail 211, and the pressing column 248 can be inserted into the slot 211-1, so that the insert block 247 can retract into the connecting body 244. A push rod 2411 is fixed to one side of the moving seat 243. Both the push rod 2411 and the end of the insert block 247 are provided with inclined surfaces.

[0064] When the movable seat 243 drives the push rod 2411 to move upward, the push rod 2411 pushes the insert block 247, thereby driving the connector 244 to move upward, which in turn drives the lifting platform 212 to move upward. When the pressing column 248 moves to the side of the slot 211-1, the sliding sleeve 233 also moves to the end of the guide groove 13-1 and falls into the reset groove 13-2. At this time, the insert block 247 moves into the connector 244 under the pressure of the push rod 2411, so that the pressing column 248 is inserted into the slot 211-1. At this time, the lifting platform 212 will stay here, while the movable seat 243 can continue to drive the push rod 2411 to move upward.

[0065] Specifically, the cutting component 14 includes a rotating shaft 141 rotatably connected to the upright plate 13, a support arm 142 fixed to one side of the rotating shaft 141, a protective shell 143 fixed to the other end of the support arm 142, a cutting disc 144 rotatably connected inside the protective shell 143, a drive motor 145 fixed to one side of the protective shell 143, and the cutting disc 144 fixed to the output end of the drive motor 145.

[0066] Starting the drive motor 145 can drive the cutting disc 144 to rotate. If the rotating shaft 141 is driven to rotate, the support arm 142 can drive the protective shell 143 to move closer to the pipe, so that the cutting disc 144 can cut the pipe.

[0067] Specifically, the cutting component 14 also includes a fan-shaped gear disk 146 fixed to the end of the rotating shaft 141, a connecting gear disk 147 rotatably connected to one side of the upright plate 13, and a rack 148 fixed to one side of the movable seat 243. The connecting gear disk 147 meshes with the rack 148 and the fan-shaped gear disk 146 respectively.

[0068] When the movable seat 243 drives the rack 148 to move upward, it can drive the connecting gear plate 147 to rotate, thereby causing the connecting gear plate 147 to drive the sector gear plate 146 to rotate, which in turn causes the sector gear plate 146 to drive the rotating shaft 141 to rotate, thereby bringing the cutting disc 144 closer to the pipe and cutting the pipe.

[0069] Before the cutting disc 144 cuts the pipe, the extrusion column 248 has been inserted into the slot 211-1, and the pipe is stably clamped by the clamping plate 217 at the end of the clamping body 216.

[0070] In summary, the present invention has the following beneficial effects:

[0071] 1. Achieve adaptive clamping and force matching for different pipe diameters: Through the coordinated action of the first spring 218 in the clamping body 216 and the second spring 219 on the swing rod 214, the first spring 218 will be compressed more when clamping pipes with larger diameters, providing greater clamping force to match their weight requirements. Different pipe diameters can be adapted without manual adjustment, improving the convenience of operation.

[0072] 2. Automatic drive to move the cut pipe away to avoid stagnation: With the help of the third spring 222, coil spring 228 and gear transmission structure of the pusher 22, when the clamp is released, the accumulator 221 is reset under the action of the third spring 222, and drives the push wheel 224 to rotate through the first toothed ring 225 and the second toothed ring 2215, pushing the cut pipe away from the main body 11 of the pipe bending machine, preventing the cut pipe from getting caught on the clamping mechanism and affecting subsequent work.

[0073] 3. Achieve precise linkage between clamping and cutting actions: The power motor 241 in the drive component 24 drives the moving seat 243 to rise and fall, and the lifting platform 212 is linked through the push rod 2411. In conjunction with the rack 148 and the connecting gear plate 147, the cutting plate 144 of the cutting component 14 is driven to move, ensuring stable clamping before cutting. After cutting, the device is reset synchronously, reducing pipe displacement and cut damage.

[0074] In use, when it is necessary to cut the bent pipe fitting, the power motor 241 is started, which drives the lead screw 242 to rotate. This causes the lead screw 242 to lift the moving seat 243, which in turn pushes the push rod 2411 against the insert block 247. This pushes the connecting body 244 upward, thereby moving the lifting platform 212 upward. When the lifting platform 212 moves upward, it causes the sliding sleeve 233 to slide within the guide groove 13-1, causing the guide groove 13-1 to squeeze the sliding sleeve 233. The pressure drives the swing arm 214 to swing, thereby causing the two support shells 215 to move closer to each other. At this time, the push wheel 224 at the end of the accumulator 221 first contacts the pipe. Under the pressure of the pipe, the push wheel 224 drives the accumulator 221 to slide into the clamping body 216, thereby compressing the third spring 222. As the support shell 215 continues to move, the clamping plate 217 at the end of the clamping body 216 clamps and supports the pipe. At this time, the extrusion column 248 has been inserted into the slot 211-1.

[0075] As the movable seat 243 continues to rise, it can bring the cutting disc 144 closer to the pipe, thereby cutting the pipe.

[0076] After the cutting is completed, the output end of the power motor 241 is rotated in reverse, thereby causing the moving seat 243 to descend and reset. At this time, the cutting disc 144 is moved away from the pipe and resets.

[0077] As the movable seat 243 descends, the push rod 2411 moves away from the insert block 247. Under the reset force of the seventh spring 2410, the insert block 247 extends out of the connector 244. At this time, the pressing column 248 moves out of the slot 211-1. Under the pull of the sixth spring 245, the lifting platform 212 can be driven to move downward to reset.

[0078] As the lifting platform 212 moves downward, the sliding sleeve 233 slides within the reset groove 13-2. When the sliding sleeve 233 slides to the other end of the reset groove 13-2, under the reset pull of the second spring 219, it can drive the swing rod 214 to swing, thereby causing the rotating column 231 to drive the sliding sleeve 233 to slide into the guide groove 13-1. As the lifting platform 212 continues to move downward, it drives the sliding sleeve 233 to reset to the starting position.

[0079] During this process, the two support shells 215 move away from each other. Since the elastic coefficient of the third spring 222 is much smaller than that of the first spring 218, the clamping plate 217 of the clamping body 216 always clamps the cut pipe fitting as the two support shells 215 move away from each other. When the clamping body 216 resets under the push of the first spring 218, the third spring 222 begins to release its elastic potential energy, causing the accumulator rod 221 to move out of the clamping body 216. This allows the cable 2210 to drive the winding wheel 229 to rotate, thereby causing the winding wheel 2210 to rotate. 9 drives the rotating sleeve 227 to rotate, which in turn drives the rotating wheel 2212 to rotate. At this time, the rotating wheel 2212 can drive the second toothed ring 2215 to rotate through the card plate 2213 that is locked in the card slot 2215-1. This causes the second toothed ring 2215 to drive the first toothed ring 225 to rotate, which in turn causes the first toothed ring 225 to drive the push wheel 224 to rotate. This causes the push wheel 224 to drive the cut pipe away from the pipe bending machine body 11, preventing the cut pipe from getting caught on the clamping part 21.
