Description

In the prior art, although the cutting function has been integrated into the pipe bending machine to try to solve the efficiency problem of traditional step-by-step processing, there are still many technical limitations in actual application.

[0003] In terms of coordination between cutting and clamping, the clamping action and the cutting action of the existing equipment are mostly independent control, lacking precise linkage mechanism.

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" 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 various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments. Example 1

[0035] Reference Figures 1-4 and Figure 11For the first embodiment of the application, the embodiment provides a pipe bending machine device with cutting function, the pipe bending machine device with cutting function comprises a main body assembly 1, the main body assembly 1 comprises a pipe bending machine main body 11, one side of the pipe bending machine main body 11 is provided with a head bending die mechanism 12, the pipe bending machine main body 11 and the head bending die mechanism 12 are prior art, the pipe bending machine main body 11 can drive the head bending die mechanism 12 to bend the pipe, and those skilled in the art should know its working principle, which is not described here, the head bending die mechanism 12 is fixed with a vertical plate 13, the vertical plate 13 is provided with a cutting piece 14, the cutting piece 14 is used for cutting the bent pipe, and the vertical plate 13 is fixed with a protective cover 15, the protective cover 15 is used for protecting the transmission part of the cutting piece 14.

[0036] The clamping assembly 2 is arranged on the vertical plate 13 and comprises a clamping piece 21 arranged on the surface of the vertical plate 13, and a sliding rail 211 fixed to the surface of the vertical plate 13. There are three sliding rails 211, two of which are slidably provided with lifting platforms 212 on the surfaces of the sliding rails 211. The surfaces of the sliding rails 211 are coated with lubricating grease to reduce friction. The lifting platforms 212 are fixed with support shafts 213 on the surfaces. The support shafts 213 are rotatably connected with two swing rods 214 on the surfaces. The swing rods 214 are fixed with support shells 215 at the ends. The support shells 215 are slidably provided with clamping bodies 216. The clamping bodies 216 are fixed with two clamping plates 217 at the other ends. The clamping plates 217 can support the clamping of pipes with different diameters. The clamping bodies 216 are fixed with first springs 218 at the other ends. The other ends of the first springs 218 are fixed to the inner walls of the support shells 215. The first springs 218 are currently in a normal state. The surfaces of the swing rods 214 are fixed with second springs 219. The other ends of the second springs 219 are fixed with support blocks 2110. The second springs 219 are currently in a stretched state. The support blocks 2110 are fixed to the surfaces of the lifting platforms 212.

[0037] When the two support shells 215 rotate around the support shaft 213 and move closer to each other, the two clamping bodies 216 in the support shells 215 move closer to each other, so that the four clamping plates 217 clamp and fix the pipe.

[0038] When the clamping bodies 216 extrude and clamp the pipe, the first springs 218 are compressed, so that the compressed first springs 218 provide clamping force for the clamping bodies 216.

[0039] Since the swing angle of the swing rod 214 is fixed, the movement trajectory of the support shell 215 is fixed during each clamping. When clamping a pipe with a larger diameter, the first spring 218 is compressed to a greater extent, so that the clamping force of the clamping body 216 on the pipe is greater, thereby matching the clamping requirement of the large-diameter pipe under the greater weight. Embodiment 2

[0050] When the force storage rod 221 moves out of the clamping body 216 under the pushing of the third spring 222, at this time, 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 the other direction, at this time, the rotating wheel 2212 can drive the second tooth ring 2215 to rotate through the clamping plate 2213 clamped in the clamping groove 2215-1, so that the second tooth ring 2215 drives the first tooth ring 225 to rotate, so that the first tooth ring 225 drives the pushing wheel 224 to rotate, so that the pushing wheel 224 drives the cut pipe away from the pipe bending machine body 11, so as to prevent the cut pipe from hanging on the clamping member 21.

Precise linkage of clamping and cutting actions: the power motor 241 in the driving member 24 drives the moving seat 243 to lift, which in turn drives the lifting platform 212 through the push rod 2411, and cooperates with the rack 148 and the connecting tooth disc 147 to drive the cutting disc 144 of the cutting member 14 to act, ensuring that the pipe is clamped stably before cutting, and resetting synchronously after cutting, reducing pipe displacement and cutting damage.

[0068] In use, when the bent pipe needs to be cut, the power motor 241 is started, driving the lead screw 242 to rotate, thereby driving the moving seat 243 to rise, the push rod 2411 pushes the insertion block 247, driving the connecting body 244 to move upwards, thereby driving the lifting platform 212 to move upwards, the sliding sleeve 233 slides in the guide groove 13-1, the guide groove 13-1 extrudes the sliding sleeve 233, driving the swing lever 214 to swing, thereby driving the two support shells 215 to move closer to each other, at this time, the pushing wheel 224 at the end of the force storage rod 221 first contacts the pipe, under the extrusion of the pipe, the pushing wheel 224 drives the force storage rod 221 to slide into the clamping body 216, thereby compressing the third spring 222, as the support shells 215 continue to move, the clamping plates 217 at the ends of the clamping body 216 clamp and support the pipe, at this time the extrusion column 248 has been inserted into the insertion groove 211-1.

[0069] As the moving seat 243 continues to rise, the cutting disc 144 approaches the pipe, thereby cutting the pipe.

[0070] After the cutting is completed, the output end of the power motor 241 is reversed to rotate, so that the moving seat 243 is lowered to reset, and the cutting disc 144 is away from the pipe to reset.

[0071] With the moving seat 243 being lowered, the push rod 2411 is away from the plug 247, and under the reset elastic force of the seventh spring 2410, the plug 247 extends out of the connecting body 244, and at this time, the extrusion column 248 moves out of the insertion slot 211-1, and under the pulling force of the sixth spring 245, the lifting platform 212 is driven to move downward to reset.

[0072] During the downward movement of the lifting platform 212, the sliding sleeve 233 slides in the reset slot 13-2, and when the sliding sleeve 233 slides to the other end of the reset slot 13-2, under the reset pulling force of the second spring 219, the swing rod 214 is driven to swing, so that the rotating column 231 drives the sliding sleeve 233 to slide into the guide slot 13-1, and with the continuous downward movement of the lifting platform 212, the sliding sleeve 233 is reset to the starting position.

[0073] During this process, the two support shells 215 are away from each other, and 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 during the process that the two support shells 215 are away from each other, and when the clamping body 216 is reset under the pushing of the first spring 218, the third spring 222 starts to release the elastic potential energy, so that the force-accumulating rod 221 starts to move out of the clamping body 216, and the cable 2210 drives the winding wheel 229 to rotate, so that the winding wheel 229 drives the rotating sleeve 227 to rotate, and the rotating sleeve 227 drives the rotating wheel 2212 to rotate, at this time, the rotating wheel 2212 can drive the second gear ring 2215 to rotate through the clamping plate 2213 clamped in the clamping groove 2215-1, so that the second gear ring 2215 drives the first gear ring 225 to rotate, so that the first gear ring 225 drives the pushing wheel 224 to rotate, so that the pushing wheel 224 drives the cut pipe to be away from the pipe bending machine body 11, preventing the cut pipe from hanging on the clamping member 21.
