[0033] It should be noted that the various connecting components mentioned above are all components with annular structures or tubular structures, such as nuts, threaded sleeves, annular pressing pieces, etc.

[0034] It should be noted that the pipe bending device 20 does not belong to the gist of the present invention. The pipe bending device 20 can be any device for bending pipes in the prior art, and the pipe bending device 20 will not be described in detail herein.

[0035] When the above-mentioned pipe bending equipment is working, the pipe feeding device 10 continuously conveys the pipe, and the pipe transfer device 40 takes out the pipe from the pipe feeding device 10 and transfers the pipe to the discharge port 3115 of each storage component 311. At the same time, each pushing component 312 pushes the connecting component outward from the corresponding discharge port 3115 to insert various connecting components into the pipe in sequence. Finally, the pipe transfer device 40 transfers the pipe inserted with various connecting components to the pipe bending device 20, and the pipe is bent into a preset shape by the pipe bending device 20. It can be seen that the above-mentioned pipe bending equipment has both the function of inserting the connecting component into the pipe and the function of bending the pipe, and can realize the rapid transfer of the pipe through the pipe transfer device 40, effectively improving the production efficiency.

[0036] In this embodiment, please combine Figures 3 to 5 As shown, the storage assembly 311 includes a storage member 3111 having a feed port 3114 and a discharge port 3115. A storage tank (not shown) is provided in the storage member 3111, and the feed port 3114 is connected to the discharge port 3115 through the storage tank. Each feeding mechanism 32 inputs a connecting component from the feed port 3114 of the storage member 3111 into the storage tank, and then the connecting component falls into the discharge port 3115 along the storage tank, and then the pipe transfer device 40 transfers the pipe to the discharge port 3115 of each storage member 3111 in turn, and each pushing assembly 312 pushes out the connecting component in the corresponding discharge port 3115 in turn, so as to insert various connecting components into the pipe in turn.

[0037] Specifically, please combine Figure 4 and Figure 5 As shown, the material pushing assembly 312 includes a first linear driver 3121, and a push rod 3122 connected to the power output end of the first linear driver 3121 and extending along the driving direction of the first linear driver 3121, and one end of the push rod 3122 away from the first linear driver 3121 is arranged opposite to the discharge port 3115 of the material storage member 3111. The first linear driver 3121 drives the push rod 3122 to move toward the material storage member 3111, so that the push rod 3122 is inserted into the discharge port 3115 of the material storage member 3111 to push the connecting component outward.

[0038] It should be noted that the first linear drive 3121 includes many types, such as an electric cylinder, a motor combined with a ball screw mechanism, a motor combined with a gear rack mechanism, etc., which are not specifically limited here.

[0039] Specifically, please combine Figure 4 and Figure 5As shown, the material storage member 3111 is provided with a guide hole 3116 and a first through hole 3117 and a second through hole 3118 both of which are connected to the material storage trough. The material storage trough of the material storage member 3111 extends in the vertical direction. The first through hole 3117 and the second through hole 3118 are respectively arranged on opposite sides of the material storage member 3111 and are arranged in sequence along the extension direction of the material storage trough. The material storage assembly 311 also includes a first positioning rod 3112 that is penetrated through the first through hole 3117 and a second positioning rod 3112 that is penetrated through the second through hole 3118. Rod 3113; the pushing assembly 312 also includes a first mounting seat 3123 connected to the power output end of the first linear drive 3121 and used to install the pushing rod 3122, and a guide rod 3124 fixedly mounted on the first mounting seat 3123 and extending along the driving direction of the first linear drive 3121, one end of the guide rod 3124 passes through the guide hole 3116 and is fixedly connected to the first positioning rod 3112, and the second positioning rod 3113 is fixedly mounted on the first mounting seat 3123. Initially, the first positioning rod 3112 is inserted into the first through hole 3117 of the material storage piece 3111 and passes through the connecting component a in the material storage slot of the material storage piece 3111, while the second positioning rod 3113 leaves the second through hole 3118 and the push rod 3122 leaves the discharge port 3115; when the first linear drive 3121 drives the first mounting seat 3123 to move toward the direction close to the material storage piece 3111, the first mounting seat 3123 drives the first positioning rod 3112 to withdraw from the first through hole 3117 through the guide rod 3124. At this time, the connecting component a passed by the first positioning rod 3112 falls off, and at the same time, the second positioning rod 3113 is inserted into The first linear drive 3121 drives the first mounting seat 3123 to move in a direction away from the material storage member 3111, and the first positioning rod 3112 is reinserted into the first through hole 3117 and passes through the connecting member b. At the same time, the second positioning rod 3113 withdraws from the second through hole 3118, and the connecting member a falls into the discharge port 3115. The first linear drive 3121 then drives the first mounting seat 3123 to move in a direction close to the material storage member 3111, and the connecting member a is pushed outward by the push rod 3122. The operation is cyclically continued to realize continuous pushing of the connecting member.

[0040] Specifically, please combine Figure 4 and Figure 5 As shown, in order to improve the operating stability of the pusher assembly 312 , the pusher assembly 312 also includes a first slide rail 3125 fixedly mounted on the frame 90 and extending along the driving direction of the first linear drive 3121 , and the first mounting seat 3123 can be slidably mounted on the first slide rail 3125 .

[0041] Specifically, please combine Figure 5As shown, the pushing assembly 312 also includes a mounting member 3126 having a connecting hole 3127, and the mounting member 3126 is connected to the end of the guide rod 3124 away from the first linear driver 3121 through the connecting hole 3127, and the first positioning rod 3112 is installed on the mounting member 3126, and the first through hole 3117 and the connecting hole 3127 are both in a strip structure extending along the extension direction of the material storage trough of the material storage member 3111. In this way, the mounting member 3126 can be positioned along the extension direction of the connecting hole 3127, thereby achieving fine-tuning of the position of the first positioning rod 3112, so that the above-mentioned discharging mechanism 31 can be applicable to a variety of connecting components and has good universal performance.

[0042] In this embodiment, please combine Figure 3 As shown, the feeding mechanism 32 includes a vibration disk 321 and a feeding track 322, one end of the feeding track 322 is connected to the vibration disk 321 and the other end is connected to the feed port 3114 of the storage component 311. By using the vibration disk 321 to transport the connecting components, the working stability of the connecting component classification output device 30 can be effectively guaranteed, and the manufacturing cost of the connecting component classification output device 30 can also be effectively reduced. When in use, various connecting components are respectively accommodated in the corresponding vibration disk 321. Under the vibration of the vibration disk 321, the connecting components enter the feeding track 322 in sequence, and enter the storage component 311 along the feeding track 322 through the feed port 3114 of the storage component 311, that is, enter the storage tank of the storage component 3111, and finally reach the discharge port 3115 of the storage component 311 and are pushed outward by the pushing component 312.

[0043] It can be understood that when two or more discharging mechanisms 31 are used to output the same type of connecting components, the connecting components can be placed in a vibration disk 321, and the vibration disk 321 is connected to multiple loading rails 322. The end of each loading rail 322 away from the vibration disk 321 is respectively connected to the corresponding discharging mechanism 31. In this way, the number of vibration disks 321 can be effectively reduced, thereby further reducing the manufacturing cost of the connecting component classification output device 30.

[0044] In this embodiment, please combine Figure 1 , Figure 6 and Figure 7 As shown, the pipe feeding device 10 includes a clamping mechanism 11, which includes a second mounting seat 111, a second linear driver 112 mounted on the second mounting seat 111, a first clamping member 114 and a second clamping member 115 slidably mounted on the second mounting seat 111, and a transmission assembly 113 connected to the power output end of the second linear driver 112. The second linear driver 112 drives the first clamping member 114 and the second clamping member 115 to move in a direction of approaching or moving away from each other through the transmission assembly 113 to clamp or release the pipe.

[0045] The clamping mechanism in a traditional pipe feeding device usually fixes one clamping member, while the other clamping member is driven by a linear drive to perform linear reciprocating motion, so that the two clamping members cooperate with each other to clamp or release the pipe. However, when changing from a clamping state to a released state, the pipe is easily attached to the fixed clamping member, thereby increasing the conveying resistance of the pipe, and eventually causing the pipe to bend and block the conveying channel. Compared with the prior art, the above-mentioned clamping mechanism 11 clamps or releases the pipe by moving the first clamping member 114 and the second clamping member 115 in a direction of approaching or moving away from each other, thereby effectively preventing the pipe from adhering to the first clamping member 114 or the second clamping member 115, and effectively improving the working reliability and stability of the pipe feeding device 10.

[0046] It should be noted that the second linear actuator 112 includes various types, such as an electric cylinder, a motor combined with a ball screw mechanism, a motor combined with a gear rack mechanism, etc., which are not specifically limited here.

[0047] Specifically, please combine Figure 7 As shown, a first notch 1141 is provided at one end of the first clamping member 114 close to the second clamping member 115, and a second notch 1151 is provided at one end of the second clamping member 115 close to the first clamping member 114. When in a clamping state, the first notch 1141 and the second notch 1151 cooperate with each other to form a clamping opening that matches the cross-sectional shape of the tube. For example, when the tube is a round tube, the cross-sections of the first notch 1141 and the second notch 1151 are both semicircular structures, and the cross-section of the formed clamping opening is a circular structure; for example, when the tube is a square tube, the cross-sections of the first notch 1141 and the second notch 1151 are both semi-square structures, and the cross-section of the formed clamping opening is a square structure.

[0048] It should be noted that the inner diameter of the clamping opening is slightly smaller than the outer diameter of the pipe to ensure that the pipe can be clamped.

[0049] Specifically, please combine Figure 7 As shown, in order to improve the operating stability of the clamping mechanism 11, a second slide rail 1111 and a third slide rail 1112 are fixedly provided on the second mounting seat 111, the first clamping member 114 is slidably mounted on the second slide rail 1111, and the second clamping member 115 is slidably mounted on the third slide rail 1112.

[0050] Specifically, please combine Figure 7As shown, the transmission assembly 113 includes a first transmission arm 1131 and a second transmission arm 1132, both of which are L-shaped structures and can be rotatably mounted on the second mounting base 111, one end of the first transmission arm 1131 is rotatably connected to the power output end of the second linear drive 112 and the other end is rotatably connected to the first clamping member 114, one end of the second transmission arm 1132 is rotatably connected to the power output end of the second linear drive 112 and the other end is rotatably connected to the second clamping member 115. During operation, when the second linear drive 112 pushes the first transmission arm 1131 and the second transmission arm 1132, the end of the first transmission arm 1131 away from the second linear drive 112 and the end of the second transmission arm 1132 away from the second linear drive 112 both swing outward, thereby driving the first clamping member 114 and the second clamping member 115 to move away from each other. At this time, the clamping mechanism 11 is in a released state; when the second linear drive 112 pulls the first transmission arm 1131 and the second transmission arm 1132, the end of the first transmission arm 1131 away from the second linear drive 112 and the end of the second transmission arm 1132 away from the second linear drive 112 both swing inward, thereby driving the first clamping member 114 and the second clamping member 115 to move towards each other. At this time, the clamping mechanism 11 is in a clamping state.

[0051] Specifically, please combine Figure 7 As shown, a first strip hole 1133 is formed at one end of the first transmission arm 1131 away from the first clamping member 114, and a second strip hole 1134 is formed at one end of the second transmission arm 1132 away from the second clamping member 115. The first transmission arm 1131 is rotatably connected to the power output end of the second linear drive 112 through the first strip hole 1133, and the second transmission arm 1132 is rotatably connected to the power output end of the second linear drive 112 through the second strip hole 1134, so as to provide a certain movable space for the first transmission arm 1131 and the second transmission arm 1132 during operation, thereby increasing the relative movement range of the first clamping member 114 and the second clamping member 115.

[0052] In this embodiment, the pipe bending device further includes a pipe cutting device 80 fixedly mounted on a frame 90, and the pipe feeding device 10 further includes a fourth linear drive 12 mounted on the frame 90, a fourth slide rail 13 extending along the driving direction of the fourth linear drive 12 and mounted on the frame 90, and two clamping mechanisms 11 arranged in sequence along the driving direction of the fourth linear drive 12, hereinafter referred to as clamping mechanism a and clamping mechanism b, wherein the clamping mechanism a is slidably mounted on the fourth slide rail 13 and connected to the power output end of the fourth linear drive 12, and the clamping mechanism b is fixedly mounted on the frame 90 and arranged adjacent to the pipe cutting device 80. During operation, the fourth linear drive 12 drives the clamping mechanism a to reciprocate along the fourth slide rail 13 to continuously transport the pipe to the pipe cutting device 80, and before the pipe cutting device 80 is started, the clamping mechanism b clamps the pipe, and then the pipe cutting device 80 is started to cut the pipe, and the cut pipe is transferred from the pipe transfer device 40 to the connection component classification output device 30.

[0053] It should be noted that the pipe cutting device 80 does not belong to the gist of the present invention. The pipe cutting device 80 can be any device for cutting pipes in the prior art, and the pipe cutting device 80 will not be described in detail here.

[0054] It should be noted that the fourth linear actuator 12 includes various types, such as an electric cylinder, a motor combined with a ball screw mechanism, a motor combined with a gear rack mechanism, etc., which are not specifically limited here.

The clamping mechanism c is connected to the power output end of the fifth linear drive. The fourth linear drive 12 drives the clamping mechanism a to reciprocate along the fourth slide rail 13 to continuously transport the pipe and allow the pipe to pass through the clamping mechanism b, the tube cutting device 80 and the clamping mechanism c in turn. After the tube cutting device 80 cuts off the pipe, the fifth linear drive drives the clamping mechanism c to move away from the tube cutting device 80, thereby realizing rapid separation of the pipe.

[0056] It should be noted that the fifth linear actuator includes many types, such as an electric cylinder, a motor combined with a ball screw mechanism, a motor combined with a gear rack mechanism, etc., which are not specifically limited here.
