Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0037] In the description of the embodiments of this application, unless otherwise specified, "multiple" means two or more. For example, "multiple processing units" means two or more processing units; "multiple systems" means two or more systems.

[0038] like Figures 3 to 9 As shown, this embodiment provides a support tube closing device that closes the front end of a support tube 100 to be closed, thereby obtaining a support tube 100 containing a tapered tube 101. It should be noted that the support frame 1, feed pipe 5, and punching cylinder 3 are simplified, and the mounting support components of the punching cylinder 3, first pushing mechanism, second pushing mechanism, and vibrating plate 4 are not shown. Conventional bracket supports can be used, which does not affect the implementation of the technology itself.

[0039] Specifically, the feeding mechanism of the support tube closing of this embodiment includes a support frame 1, a stamping die assembly 2 fixed on the support frame 1, a stamping cylinder 3 connected to the stamping die assembly 2, a material receiving and pushing mechanism 6 and a rotary feeding mechanism 7 arranged on the support frame 1, a feeding pipe 5 connected to the material receiving and pushing mechanism 6, a vibration plate 4 connected to the feeding pipe 5, a first pushing link 8 connected to the material receiving and pushing mechanism 6 and driving the material receiving and pushing mechanism 6, a second pushing link 9 connected to the rotary feeding mechanism 7 and driving the rotary feeding mechanism 7, a first pushing mechanism (not shown) connected to the first pushing link 8, a second pushing mechanism (not shown) connected to the second pushing link 9, and a material withdrawing cylinder assembly 10 fixed on the support frame 1. Among them, the material withdrawing cylinder assembly 10 and the stamping die assembly 2 are coaxially arranged on both sides of the support frame 1. Among them, the first pushing mechanism and the second pushing mechanism are conventional pushing mechanisms, such as cylinders.

[0040] In this embodiment, a vibrating plate 4 is used to vibrate and load the materials one by one. A feed pipe 5 then transfers the support tubes 100 to be closed by the material receiving and pushing mechanism 6. A rotary feed mechanism 7 then clamps the support tubes 100 to be closed from the material receiving and pushing mechanism 6 and places them on the stamping die assembly 2. The stamping cylinder 3 drives the stamping die assembly 2 to perform the stamping and closing. After the support tube 100 is closed, the ejector cylinder assembly 10 ejects the support tube 100 containing the tapered tube 101 from the stamping die assembly 2, allowing the closing of the next support tube 100 to proceed.

The support tube 100 to be closed enters from the first circular hole 211 (pressed in by the die head 24), is closed at the tapered hole 212, and then the support tube 100 is ejected from the second circular hole 213 by the material-removing cylinder assembly 10.

[0042] In this embodiment, the material receiving and pushing mechanism 6 includes a first mounting platform 61 fixed to the support frame 1, a slide rail seat 62 fixed to the first mounting platform 61, a slide rail 63 slidably mounted on the slide rail seat 62, a material receiving seat 64 fixed to one end of the slide rail 63 and close to the side of the stamping die assembly 2, a rotating support shaft 65 fixed to the first mounting platform 61, and a first L-shaped crank arm 66 having a middle portion rotatably connected to the rotating support shaft 65, one end transmission-connected to the slide rail 63, and the other end axially connected to the first pushing link 8. Among them, a first connecting rod connecting hole 662 is provided on the first L-shaped crank arm 66, and the first connecting rod connecting hole 662 is axially connected to the first pushing link 8.

[0043] To ensure reliable lateral movement of the slide rail 63, a connecting post 631 is provided on the slide rail 63, and a first strip hole 661 is provided on the first L-shaped arm 66. The connecting post 631 is inserted into the first strip hole 661. When the first L-shaped arm 66 rotates, the connecting post 631 slides along the first strip hole 661, driving the slide rail 63 to move lateral.

[0044] In this embodiment, to ensure reliable material connection and clamping, a transverse slot 641 and a longitudinal slot 642 are formed on the material receiving base 64. The outlet of the feed pipe 5 is connected to the longitudinal slot 642. The pipe clamp mechanism is inserted into the transverse slot 641 and clamps the support pipe 100 to be closed in the longitudinal slot 642.

[0045] In this embodiment, the rotary feeding mechanism 7 includes a rotating shaft seat 71 fixed to the support frame 1, a rotating shaft 72 rotatably mounted on the rotating shaft seat 71, a connecting rod crank arm 73 provided at one end of the rotating shaft 72 and connected to the second push link 9, a second L-shaped crank arm 74 provided at the other end of the rotating shaft 72, and a pipe clamp mechanism fixed to the second L-shaped crank arm 74. The clamp mechanism clamps the support tube 100 to be closed in the longitudinal slot 642.

[0046] In this embodiment, the pipe clamp mechanism includes a T-shaped sandwich plate 751 fixed to a second L-shaped crank arm 74, a right clamping plate 752 and a left clamping plate 753 disposed on the sides of the T-shaped sandwich plate 751, an array of elastic connection components that elastically clamp and connect the right clamping plate 752, the T-shaped sandwich plate 751, and the left clamping plate 753, and clamping grooves 756 formed at the front ends of the right clamping plate 752, the T-shaped sandwich plate 751, and the left clamping plate 753. A second strip-shaped hole 7511 is formed in the T-shaped sandwich plate 751, and a locking screw assembly 754 is disposed on the second L-shaped crank arm 74 and is disposed within the second strip-shaped hole 7511. In this manner, the position of the pipe clamp mechanism can be adjusted. In addition, the elastic connection assembly includes an extrusion screw 7551 disposed through the right clamping plate 752, the T-shaped sandwich plate 751, and the left clamping plate 753, a spring 7552 sleeved on the extrusion screw 7551, and a first nut 7553 disposed at the end of the extrusion screw 7551. The spring 7552 compresses the left clamping plate 753, causing the right clamping plate 752 to fit against the T-shaped sandwich plate 751, and the T-shaped sandwich plate 751 to fit against the left clamping plate 753, thereby providing a tightening force to clamp the support tube 100.

[0047] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any changes based on the design principles of the present invention and any changes made through non-creative work on this basis shall fall within the scope of protection of the present invention.
