[0002] Most special-shaped three-way pipe fittings are made of copper pipes. Copper pipes have advantages such as good ductility and corrosion resistance. However, when directly bending the copper pipes, the bent parts will appear flat, which affects the subsequent processing and use of the copper pipes. Therefore, before bending the copper pipes, it is necessary to fill the inside of the copper pipes with materials, and the materials play a supporting role for the copper pipes. When the copper pipes are bent, the flat state at the bent parts can be avoided.

A guide column 75 is slidably connected in the guide sleeve 72. The bottom of the guide column 75 is connected to the pressure plate 74. The cooperation of the guide sleeve 72 and the guide column 75 prevents the pressure plate 74 from shifting when moving up and down.

[0052] The left and right sides of the frame 1 are respectively provided with an end face assembly 6 and a top material assembly 5, and the end face assembly 6 and the top material assembly 5 limit the position of the copper tube in the X-axis direction;

[0053] like Figure 8As shown, the end face assembly 6 is located between the frame 1 and the filling device 2, and the end face assembly 6 includes an end face block 61 and an end panel 63. The end panel 63 is installed on the frame 1. An end face cylinder 64 is provided on the end panel 63. The telescopic end of the end face cylinder 64 is connected to the end face block 61. The end face block 61 is provided with a feeding hole 62 that passes through the left and right sides. The material output from the output end of the filling device 2 passes through the feeding hole 62 into the inside of the copper tube. The end panel 63 connects the inside of the copper tube with the output end of the filling device 2, and the end panel 63 can slide in the vertical direction. After the filling is completed, the end panel 63 moves upward to scrape the left end of the copper tube to prevent the material from falling and polluting the working environment.

[0055] The rear side of the frame 1 is also provided with a loading assembly 3 for loading the copper tubes one by one.

[0056] like Figure 9 As shown, the feeding assembly 3 includes a feeding rack 31 and a mounting plate 34. The feeding rack 31 is connected to the mounting plate 34 via a mounting rod 35. The mounting plates 34 are provided with two groups. The spacing between the two groups of mounting plates 34 is adjusted to adapt to the length specifications of copper tubes. A feeding rotating rod 32 is also rotatably connected between the two groups of mounting plates 34. The feeding rotating rod 32 is driven by a feeding motor 33. A shifting block 36 for shifting the copper tube is also provided on the feeding rotating rod 32. A support plate 37 for supporting the copper tube is also provided between the two groups of mounting plates 34.

[0057] A guide plate 38 is further provided between the two groups of mounting plates 34. The guide plate 38 is provided above the support plate 37. Under the guidance of the guide plate 38, the copper tubes are evenly arranged on the support plate 37. A flap 39 is further hinged on the guide plate 38. A torsion spring is further provided between the flap 39 and the guide plate 38. Under the limitation of the flap 39, the copper tube cannot slide off the support plate 37 under the action of its own gravity. The shifting block 36 rotates to push the copper tube to slide along the support plate 37, so that the flap 39 rotates around the hinge with the guide plate 38 under the push of the copper tube, and the torsion spring stores force at the same time.

[0058] A loading cylinder 310 is installed on the mounting rod 35 through a pushing rack 312. The loading cylinder 310 is tilted, and a loading plate 311 is also provided on the telescopic end of the loading cylinder 310 to push the copper tubes away from the support plate 37. Driven by the loading cylinder 310, the loading plate 311 pushes a group of copper tubes to break away from the limit of the flap 39 and fall on the transfer assembly 4. The loading plate 311 is reset to push the copper tubes on the support plate 37 backwards to prevent the copper tubes from being stacked and stuck between the support plate 37 and the guide plate 38.

[0059] A material transfer assembly 4 is provided between the loading assembly 3 and the frame 1;

[0060] like Figure 10 As shown, the material transfer component 4 includes a support plate 41 and a material transfer frame 44. The support plate 41 is located between the loading component 3 and the frame 1. The support plate 41 is provided with two groups. The bottoms of the two groups of support plates 41 are provided with telescopic cylinders 42 that drive them to move in the Z-axis direction. The support plate 41 is also provided with a bracket 46 for supporting the copper tube. Driven by the telescopic cylinder 42, the support plate 41 is initially located below the support plate 37, so that the copper tube falls into the bracket 46 on the support plate 41. When transferring materials, the support plate 41 is located above the sliding die seat 92 to place the copper tube on the sliding die seat 92; the material transfer frame 44 is installed on the frame 1, and a material transfer cylinder 45 is provided on the material transfer frame 44.

[0061] The front side of the frame 1 is provided with a discharge assembly 10 for automatically discharging the filled copper tubes.

[0062] like Figure 7As shown in the figure, the discharging assembly 10 includes a discharging plate 101 and a mounting base 104. The mounting base 104 is arranged on the front side of the frame 1. A discharging rotating rod 103 is rotatably connected to the mounting base 104. The longitudinal section of the discharging rotating rod 103 is hexagonal. The discharging rotating rod 103 is driven by a discharging motor. A discharging plate 101 is connected to the discharging rotating rod 103 through a discharging seat 102. There are two groups of discharging plates 101, which are symmetrically arranged on both sides of the sliding die base 92.

[0063] The working principle of the present invention: When in use, the device is powered on and connected to an external PLC control center, and the opening and closing of the electrical appliances in the device are controlled through the PLC control center;

[0064] The staff feeds the copper tubes to be filled through the feeding assembly 3. The copper tubes are placed between the supporting plate 37 and the guiding plate 38, and the supporting plate 37 is inclined. Under the action of its own gravity, the copper tubes slide along the supporting plate 37. The guiding plate 38 can make the copper tubes arranged one by one on the supporting plate 37 to avoid stacking; Under the action of its own gravity, the copper tubes roll to the hinge joint of the guiding plate 38 and the turning plate 39. Under the limitation of the turning plate 39, the copper tubes stay on the supporting plate 37. Control the feeding motor 33 to work, drive the feeding rotating rod 32 to rotate, and then drive the dial 36 to rotate. The dial 36 pushes the copper tubes to move downward along the supporting plate 37, driving the turning plate 39 to rotate around the hinge joint with the guiding plate 38, and the torsion spring stores energy. At this time, the copper tubes stop moving under the limitation of the turning plate 39 and the torsion spring;

[0065] Control the feeding cylinder 310 to work and extend, drive the feeding plate 311 to move towards the copper tubes, and push a group of copper tubes towards the frame 1 (move forward on the supporting plate 37). During the movement of the copper tubes, the turning plate 39 rotates around the hinge joint with the guiding plate 38, and the torsion spring stores energy again. When the pushed copper tubes are separated from the turning plate 39, the turning plate 39 is reset for the first time under the action of the torsion spring, pressing the subsequent copper tubes to avoid the movement of the subsequent copper tubes. The pushed copper tubes roll onto the tray 41 in the material transfer assembly 4 and are embedded in the tray grooves 46. Control the feeding cylinder 310 to reset. When the feeding plate 311 resets, drive the copper tubes on the supporting plate 37 to move backward, effectively avoiding the copper tubes being stuck between the supporting plate 37 and the guiding plate 38. The turning plate 39 is reset for the second time under the action of the torsion spring. The copper tubes move to the hinge joint of the turning plate 39 and the guiding plate 38 under the action of their own gravity, waiting for the next feeding operation;

[0066] There are multiple groups of tray grooves 46 on the tray 41. The copper tubes cannot accurately fall into the tray grooves 46. Control the material transfer cylinder 45 to work and extend, drive the material arranging plate 43 to move downward. The bottom of the material arranging plate 43 is provided with an inclined surface. Under the action of the inclined surface, the copper tubes are evenly distributed in the tray grooves 46;

[0067] Control the return of the transfer cylinder 45. At the same time, control the telescopic cylinder 42 to work and extend, driving the support plate 41 to move upward, so that the support plate 41 is located above the limit die 9. Control the moving cylinder 81 to work and extend, driving the sliding die base 92 to move through the moving connecting rod 82 and the moving connecting plate 83. The moving track of the sliding die base 92 is an inclined straight line. When the support plate 41 and the sliding die base 92 are in the same longitudinal section, control the telescopic cylinder 42 to return, driving the copper tube to move downward, and place the copper tube in the installation groove 95 on the sliding die base 92. Control the moving cylinder 81 to return. Since the moving cylinder 81 is inclined, when the moving cylinder 81 drives the sliding die base 92 to return, the copper tube on the sliding die base 92 falls into the installation groove 95 on the left die base 91 and the right die base 93, completing the feeding and transfer of the copper tube;

[0068] Control the end face cylinder 64 in the end face assembly 6 to work and extend, driving the end face block 61 to move downward, so that the material passing hole 62 corresponds to the position of the copper tube. At the same time, the material passing hole 62 corresponds to the output end of the filling device 2. Control the ejector cylinder 53 to work and extend, driving the ejector connecting plate 54 to slide in the sliding groove 94 on the right die base 93. The copper tube ejector rod 55 drives the ejector plate 51 to tightly limit the copper tube, and at the same time makes the copper tube contact the end face block 61;

[0069] Control the limit cylinder 73 to work, driving the pressure plate 74 to move downward to tightly limit the copper tube;

[0070] Control the filling device 2 to work, and fill the material in the filling device 2 into the copper tube. Since the length dimension of the copper tube is large and the filling pressure is large, after the material contacts the ejector plate 51, it will push the ejector plate 51 to move to the right. At this time, the spring 56 plays a role of buffering and maintaining pressure, avoiding damage to the ejector cylinder 53 due to impact;

[0071] After filling is completed, control each component to return. When the end face block 61 moves upward, the end face block 61 scrapes the left end of the copper tube to prevent the material from flowing out from the left end of the copper tube. Control the unloading motor to work, driving the unloading rotating rod 103 to rotate on the mounting seat 104, and at the same time driving the unloading plate 101 to rotate, ejecting the filled copper tube from the installation groove 95 on the limit die 9, and rolling along the unloading plate 101 to complete the unloading operation of the copper tube. Repeating the above steps can realize the automatic feeding, filling, and unloading processing of the copper tube.

[0072] The electromechanical connection involved in the present invention is a common means adopted by those skilled in the art and can obtain technical inspiration through a limited number of tests, belonging to well-known common sense.
