The tubular workpiece 800 is accommodated in the first fixing channel and can abut against the side wall of the first fixing channel to fix the tubular workpiece 800, which can improve the yield rate of the tubular workpiece 800. It will not be described in detail here. In addition, the specific structure of the second fixing assembly 120 is similar to that of the first fixing assembly 110, which will not be described in detail here.

[0048] It should be pointed out that, referring to Fig.13The tubular workpiece production device also includes a cutting mechanism 600, which includes a cutting support 610, a straightening wheel assembly 620, a cutting assembly 630 and a tube feeding assembly 640. The frame 100 is provided with a third fixing assembly 130 for fixing the tubular workpiece 800.

The tube delivery assembly 640 can deliver the tubular workpiece 800 to the straightening channel under the action of the motor to straighten the tubular workpiece 800. Afterwards, the tubular workpiece 800 moves to the first fixing assembly 110, and the cutting assembly 630 cuts the tubular workpiece 800 so that the length of the tubular workpiece 800 meets the process requirements, which is not limited here.

[0049] It should be pointed out that, referring to Fig.13 The tubular workpiece production device also includes a second transport mechanism 700, which is used to transport the tubular workpiece 800 on the third fixing assembly 130 to the first fixing assembly 110. The specific structure of the second transport mechanism 700 is similar to that of the first transport mechanism 500, and will not be described in detail herein.

[0050] Reference Figure 3 , Figure 4 In some embodiments of the utility model, the sealing component 420 includes a sealing die head 421, and the third driving component 430 includes a first slide 431, a first driving member 432 and a second driving member 433. The first slide 431 can be slidably disposed on the sealing bracket 410 and connected to the first driving member 432. The sealing die head 421 can be rotatably disposed on the first slide 431 and connected to the second driving member 433. The sealing die head 421 is provided with a sealing groove 422. Along the concave direction of the sealing groove 422, the width of the sealing groove 422 gradually decreases. The side wall of the sealing groove 422 can abut against the end of the tubular workpiece 800, and can seal the end of the tubular workpiece 800 to meet the use requirements of the tubular workpiece 800.

[0051] Specifically, the side wall of the sealing groove 422 is a spherical structure. When the sealing assembly 420 is working, the second driving member 433 drives the sealing die 421 to rotate at high speed, and the first driving member 432 drives the first slide 431 to move in a direction close to the second fixed assembly 120, so that the sealing die 421 can abut against the end of the tubular workpiece 800. When the end of the tubular workpiece 800 abuts against the side wall of the sealing groove 422, the end of the tubular workpiece 800 gradually bends, and the diameter of the end of the tubular workpiece 800 gradually decreases, so that the end of the tubular workpiece 800 can be sealed to meet the use requirements of the tubular workpiece 800.

[0052] It should be noted that the side wall of the sealing groove 422 may also be a conical structure, as long as it can seal the end of the tubular workpiece 800, and there is no limitation here.

[0053] Of course, in some specific implementations, the second driving member 433 may drive the tubular workpiece 800 to rotate at high speed, while the sealing die head 421 does not rotate, and the end of the workpiece can also be sealed, which will not be described in detail here.

[0054] Reference Figure 4 , Figure 5 In some embodiments of the present invention, a heat dissipation hole 423 is provided on the side wall of the sealing groove 422 . The heat dissipation hole 423 passes through the sealing die 421 , and can quickly dissipate the heat generated during sealing to increase the service life of the sealing die 421 .

[0055] Specifically, a plurality of heat dissipation holes 423 are configured, and the plurality of heat dissipation holes 423 are arranged at intervals along the circumference of the sealing die 421. When the end of the tubular workpiece 800 rubs against the sealing die 421 at high speed, a large amount of heat is generated. By setting a plurality of heat dissipation holes 423, the heat generated during sealing can be quickly dissipated to increase the service life of the sealing die 421.

[0056] Reference Figure 3 In some embodiments of the utility model, two sealing components 420 are configured, and the two sealing components 420 are respectively located on opposite sides of the second fixing component 120. One of the two sealing components 420 is used to seal one end of the tubular workpiece 800, and the other is used to seal the other end of the tubular workpiece 800, so that the sealing mechanism 400 can seal both ends of the tubular workpiece 800 at the same time, which can improve the production efficiency of the tubular workpiece production device.

[0057] Specifically, the sealing assembly 420 corresponds to the third driving assembly 430 one by one, one of the two sealing assemblies 420 is located on one side of the length direction of the tubular workpiece 800, and the other is located on the other side of the length direction of the tubular workpiece 800. When the sealing mechanism 400 is working, the two sealing assemblies 420 seal both ends of the tubular workpiece 800 at the same time, so that the sealing mechanism 400 can seal both ends of the tubular workpiece 800 at the same time, which can improve the production efficiency of the tubular workpiece production device.

[0058] Of course, in some specific implementations, the number of sealing components 420 may be selected according to the actual process requirements of the tubular workpiece 800. When only one end of the tubular workpiece 800 needs to be sealed, a single sealing component 420 may be selected, and there is no limitation here.

[0059] Reference Figures 6 to 8 In some embodiments of the utility model, the punching assembly 220 includes a core shaft 221, a punch 222 and a push rod 223. The core shaft 221 is movably arranged on the punching bracket 210 and is provided with an avoidance channel. The side wall of the avoidance channel is provided with a first through hole. The core shaft 221 is used to be inserted into the interior of the tubular workpiece 800. One end of the punch 222 is movably penetrated through the first through hole to enter or exit the first through hole. A pushing structure is provided between one end of the push rod 223 and the other end of the punch 222. The other end of the push rod 223 is connected to the first driving assembly 230. Through the pushing structure, the push rod 223 drives the punch 222 to move away from one end of the push rod 223 in the direction of entering or exiting the first through hole. When the punch 222 punches the tubular workpiece 800, the punch 222 is ejected from the inside of the tubular workpiece 800 to the outside, and can punch the tubular workpiece 800 to improve the production efficiency of the tubular workpiece 800.

[0060] Specifically, when the punching mechanism 200 is working, the core shaft 221 is inserted into the interior of the tubular workpiece 800, and the first driving assembly 230 drives the push rod 223 to move in a direction close to the first fixing assembly 110. The push rod 223 drives the punch 222 to withdraw from the first through hole through the pushing structure, so that the punch 222 is pushed out from the inside of the tubular workpiece 800 to the outside, and the tubular workpiece 800 can be punched. When the tubular workpiece 800 is punched, the first driving assembly 230 drives the push rod 223 to move in the opposite direction. Through the pushing structure, the push rod 223 drives the punch 222 to move in a direction of entering the first through hole, so that the punch 222 does not interfere with the tubular workpiece 800, which can facilitate the first conveying mechanism 500 to transfer the punched tubular workpiece 800 to the second fixing assembly 120, thereby improving the production efficiency of the tubular workpiece 800.

[0061] Reference Figure 8 , Fig. 9In some embodiments of the utility model, the first driving assembly 230 includes a second slide 231, a third driving member 232 and a fourth driving member 233.
