[0033] Reference Figures 1 to 4 The embodiments of the present invention are further described.

[0034] The specific structure of this embodiment includes a frame 1, on which are provided a material unloading component 3, a material base 4, a first station, a second station, a material guiding station and a third station.

[0035] The frame 1 is assembled from steel parts, and a transmission unit for driving the material holder 4 to rotate is provided on the frame 1.

[0036] The unloading component 3 is used to store the rods 1a to be processed. During processing, the rods 1a automatically fall from the unloading component 3 onto the material seat 4. There is a track 31 on the unloading component 3 for the rods 1a to roll down. The track 31 is inclined, and the output port of the track 31 is close to the material seat 4.

[0037] The material seat 4 is used to receive the rod 1a dropped from the above-mentioned unloading component 3. A plurality of station grooves 40 for the rod 1a to fall into are opened on the outer peripheral wall of the material seat 4. The station grooves 40 are U-shaped.

[0038] At the first station, when the rod 1a is delivered to the first station by the material holder 4, a process of enlarging the diameter of one end 01 of the rod 1a is performed;

[0039] The second station will squeeze the other end 02 of the rod 1a so that the edge of the end 02 is folded inward to achieve the hemming process;

[0040] The material guide station sends the rod 1a from the material holder 4 after the above two processes to the third station for processing;

[0041] At the third workstation, two cuts 100 are cut on the port with an enlarged diameter on the rod 1a. The cuts 100 are used to increase the tension of the rod 1a.

[0042] A motor is provided under the frame 1, and a transmission shaft is passed through the center of the material holder 4. One end of the transmission shaft is connected to the output end of the motor through a belt, and the other end of the transmission shaft is connected to the bearing installed on the frame 1.

[0043] A blocking component 2 is provided on the frame 1 .

[0044] The blocking component 2 includes a connecting rod 21 and a base 22. The base 22 is connected to the frame 1 via the connecting rod 21. The base 22 is connected to an axle 23 via a pin. There are three sets of axles 23, which are rotatably connected to the base 22. The axles 23 abut against the outer wall of the material holder 4, and the two outer sets of axles 23 are provided corresponding to the first and second workstations.

[0045] When the motor is working, the drive shaft rotates with the material base 4 to realize the change of the position of the work slot 40, so that the rod 1a in the work slot 40 is processed at different positions. During this period, the axle 23 will press on the rod 1a to maintain the stability of the rod 1a in the work slot 40.

[0046] The first station includes a first support portion 51 and a first movable support rod 52 placed on both sides of the material holder 4.

[0047] The output end of the first movable support rod 52 is provided with an expansion body 521 that extends into the end of the rod 1a to expand it. The expansion body 521 is bottle-shaped.

[0048] The frame 1 is provided with a first power unit that drives the first movable strut 52 to squeeze the inner edge of one end of the rod 1a. The first power unit is a first cylinder 101, and the first movable strut 52 is installed on the output end of the first cylinder 101.

[0049] When the work station slot 40 moves to the first work station, the first cylinder 101 drives the first movable support rod 52 to squeeze one end of the rod 1a. At this time, the other end of the rod 1a will press against the first support part 51. Since the flared body 521 is bottle-shaped, that is, its diameter increases from the head to the tail, when the flared body 521 extends into the port of the rod 1a, it will squeeze the port outward, causing the port to expand.

[0050] The second station includes a second support portion 61 and a second movable support rod 62 placed on both sides of the material holder 4. The frame 1 is provided with a second power unit that drives the second movable support rod 62 to squeeze the outer edge of the other end of the rod 1a.

[0051] The second power unit is a second cylinder 102 , and the second movable strut 62 is installed on the output end of the second cylinder 102 .

[0052] The second movable support rod 62 and the first movable support rod 52 are respectively located on the left and right sides of the material holder 4, so that the first and second workstations can respectively process the first and second ends of the rod 1a. Furthermore, the first support portion 51 and the second support portion 61 are also on both sides, and the first support portion 51 and the second support portion 61 have the same structure.

[0053] The end surfaces of the first supporting portion 51 and the second supporting portion 61 are curved surfaces convex outwards, and are used for the end of the rod 1 a to abut against them.

[0054] A surrounding body 63 is provided on the output end of the second movable support rod 62, and the surrounding body 63 has a recess 630 for the other end of the rod 1a to extend into, so that the outer edge of the end of the rod 1a is surrounded inward when the recess 630 squeezes the outer edge of the end of the rod 1a, and a guide column is provided at the center of the recess 630.

[0055] When the work station slot 40 rotates to the second work station, the second cylinder 102 drives the output end enclosure 63 of the second movable support rod 62 to squeeze the other end of the rod 1a, and then it is resisted by the port of the rod 1a expanded by the first work station and the second support part 61. When the enclosure squeezes the end of the rod 1a, the outer edge of the port will be folded inward, so that the port forms an inner enclosure.

[0056] There are a receiving tray 71 and a feeding frame 72 in the material guiding station. The receiving tray 71 is placed below the feeding frame 72. The receiving tray 71 is connected to the feeding cylinder 73. The feeding frame 72 includes a slope for the rod 1a to roll down and a surrounding plate surrounding the outside of the slope. The top of the slope is close to the material seat 4, and there is a receiving trough 70 arranged on the receiving tray 71 below the bottom end of the slope.

[0057] When the rod 1a falls into the feeding frame 72 from the station slot 40 of the material holder 4, it will slide along the inclined surface and fall into the receiving slot 70 of the receiving tray 71, and then the feed cylinder 73 controls the receiving tray 71 to move outward to just below the robot arm of the third station.

[0058] The third workstation includes mechanical components for clamping the rod 1a and cutting components for cutting the ends of the rod 1a.

[0059] The mechanical components include a manipulator, a translation cylinder 82 and a lifting cylinder 83.

[0060] The manipulator is a finger cylinder 81 , and a clamping portion for clamping the rod 1 a is provided at the output end of the finger cylinder 81 . In view of the tubular structure of the rod 1 a , the end face of the clamping portion is in an arc shape.

[0061] The finger cylinder 81 is controlled by the electromagnetic valve to provide a clamping force, and its clamping portion can clamp the rod 1a.

[0062] The manipulator is connected to the output end of the lifting cylinder 83 so that it is controlled by the lifting cylinder 83 to move along the Y-axis direction. The lifting cylinder 83 is connected to the output end of the translation cylinder 82 so that the manipulator is controlled to move along the X-axis direction. The translation cylinder 82 is connected to the frame 1.

[0063] The cutting component includes a positioning seat 9 and two cutting machines 10 , which are respectively placed on both sides of the positioning seat 9 . The cutting machine 10 includes a hydraulic cylinder 111 and a cutter 112 . The cutter 112 is connected to the output end of the hydraulic cylinder 111 .

[0064] A positioning body 91 is fixed in the middle of the positioning seat 9. The positioning body 91 and the positioning seat 9 can be fixed by a screw through a hole punched in the center of the positioning body 91, and then the screw passes through the center hole and the blind hole on the positioning seat 9 for threaded connection.

[0065] The positioning seat 9 is provided with two blocks 92 arranged on both sides of the positioning body 91. There is a gap between the block 92 and the positioning body 91. The block 92 is provided with an opening for the reciprocating movement of the cutter 112. The opening and the gap are connected. When the rod 1a is clamped by the finger cylinder 81 and then moved to the positioning body 91 by the translation cylinder 82, the enlarged port of the rod 1a is just inserted into the gap, and then the hydraulic cylinder 111 drives the cutter 112 to cut two openings in the rod 1a.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
