[0021] As shown in the accompanying Figure 1 to the accompanying Figure 3 drawings:

[0022] The utility model provides a kind of stainless steel seamless steel tube full-automatic drawing device, including drawing frame 1, multiple feeding auxiliary machine 2, feeding roller 3, push tube equipment 4, drawing die holder 5 and support body 6, the drawing frame 1 side is provided with the multiple feeding auxiliary machine 2, the drawing frame 1 is rotatably installed with several feeding roller 3, and two ends are fixedly installed with the push tube equipment 4 and drawing die holder 5, the drawing frame 1 and push tube equipment 4 are all fixedly installed with the support body 6.

[0023] The multiple feeding auxiliary machine 2 includes support seat 21, drive shaft 22, drive motor 23, feeding arm 24, conveying wheel 25, pipe clamping groove 26, storage groove 27, pin shaft 28, clockwork spring 29 and baffle 20, the support seat 21 is provided with two, two support seat 21 is located in the side of drawing frame 1;Two support seat 21 is rotatably installed on the drive shaft 22, and the drive shaft 22 is rotatably penetrated in one of the support seat 21, and is fixed with the drive motor 23 output end fixedly installed outside the support seat 21;At least two feeding arms 24 are fixedly installed on the drive shaft 22, a plurality of conveying wheels 25 are rotatably installed on the two side surfaces of the feeding arm 24, two groups of pipe clamping grooves 26 are respectively formed in the two ends of the feeding arm 24, the pin shaft 28 is fixedly installed in the storage groove 27 formed in the feeding arm 24, and the baffle 20 is installed and arranged on the pin shaft 28 by the clockwork spring 29.

[0024] One side of the multiple feeding auxiliary machine 2 is provided with a steel pipe feeding machine, which is used to supply the steel pipe products required for processing.

[0025] Embodiment one:

[0026] Specifically, the feeding arm 24 is designed as a rectangular plate structure, which not only provides sufficient strength and stability, but also ensures the smooth transition of the steel pipe during feeding. The shape of the rectangular plate body enables the feeding arm 24 to uniformly bear multiple steel pipes, avoiding problems caused by local stress concentration. The feeding arm 24 is located above the two feeding rollers 3, which ensures that the steel pipe can smoothly enter between the two feeding rollers 3 after leaving the feeding arm 24, and then be pushed to the drawing die holder 5. At the same time, the feeding arm 24 is also located between the two support seats 21, which provides a stable mounting base for the feeding arm 24, ensuring its stability and reliability during operation.

[0027] Specifically, two sets of pipe-clamping grooves 26 are provided on the feeding arm 24, each set being a "U"-shaped groove. This "U"-shaped design can closely conform to the shape of the steel pipe, preventing the steel pipe from shifting or falling off during sliding. The two sets of pipe-clamping grooves 26 are respectively located above one end and below the other end of the feeding arm 24, and the two sets of pipe-clamping grooves are rotationally mirrored. This layout allows the steel pipe to form a continuous and stable sliding path on the feeding arm 24, improving the accuracy and efficiency of feeding.

[0028] Specifically, the receiving grooves 27 are designed as "L"-shaped grooves, which are respectively formed on one side wall of the tube clamping groove 26 and on the surface of the feeding arm 24. This "L"-shaped design provides sufficient rotation space and installation base for the baffle 20, ensuring that the baffle 20 can flexibly perform its sealing and unlocking functions.

[0029] Specifically, the baffle 20 has an "L"-shaped structure and is installed at the included angle of the receiving groove 27 via a pin 28. When the steel pipe slides into the pipe clamping groove 26 and comes into contact with the baffle 20, the impact force and gravity of the steel pipe cause the baffle 20 to rotate, simultaneously compressing the spring 29. During this process, the baffle 20 gradually stops restricting the steel pipe from moving towards the opening of the pipe clamping groove 26, providing a basis for allowing the steel pipe to subsequently fall into the groove. This design not only achieves automatic feeding and sealing of the steel pipe but also ensures the continuity and stability of the feeding process.

[0030] Example 2:

[0031] First, the pre-bundled steel pipes are placed on a dedicated steel pipe feeder next to the multi-pipe feeding auxiliary machine 2. The cable ties on the steel pipes are then manually removed to ensure smooth transport. After starting the steel pipe feeder, it automatically transports individual steel pipes one by one to the starting end of the multi-pipe feeding auxiliary machine 2, i.e., one end of the feeding arm 24. At this time, the drive motor 23 starts, causing all feeding arms 24 to slowly tilt to a predetermined angle. During this tilting process, the steel pipes located at one end of the feeding arm 24, relying on this tilt angle, naturally slide down the surface of the feeding arm 24 to the other end. The carefully arranged conveyor wheels 25 on the feeding arm 24 play a crucial role at this time; they rotate as the steel pipes slide, effectively reducing the friction between the steel pipes and the surface of the feeding arm 24, ensuring smooth and unobstructed sliding of the steel pipes.

[0032] When the steel pipe slides to the position of the pipe clamping groove 26 at the front end, it will contact the baffle 20 arranged at this position. Under the impact force and gravity of the steel pipe, the baffle 20 rotates, and at the same time, the clockwork spring 29 connected thereto is compressed. This process facilitates the steel pipe to fall into the pipe clamping groove 26 and reach the predetermined position. Before and after the steel pipe reaches the predetermined position, the baffle 20 rotates by 90 degrees in total, and one end thereof is pressed by the steel pipe in the pipe clamping groove 26, and the other end accurately blocks the upper opening of the pipe clamping groove 26, effectively preventing the subsequent steel pipe from entering and providing a stable support surface for the sliding of the subsequent steel pipe.

[0033] With the continuous operation of the steel pipe feeding machine, the subsequent steel pipe will pass through the baffle 20 rotated to the appropriate position, smoothly transition to the upper side of the next pipe clamping groove 26, and repeat the above process until all the pipe clamping grooves 26 are filled with steel pipes.

[0034] When all the pipe clamping grooves 26 are fully loaded, the driving motor 23 is started again to drive the feeding arm 24 to rotate by 90 degrees as a whole (according to the situation, only the steel pipe can be placed on the feeding roller 3). During this process, the steel pipe in the pipe clamping groove 26 remains stationary due to the blocking action of the feeding roller 3. At this time, the pressure of the steel pipe on one end of the baffle 20 disappears, and the clockwork spring 29 releases the elastic force to push the baffle 20 back to its original position. The reset baffle 20 no longer restricts the steel pipe, and the steel pipe is thus stranded between the feeding rollers 3, ready for the next stage of processing.

[0035] Subsequently, the pipe pushing device 4 is started, and its strong pushing force pushes the ends of multiple steel pipes through the drawing die seat 5 at the same time. At this time, the drawing trolley quickly clamps the front end of the steel pipe and slowly pulls it until the entire steel pipe passes through the drawing die seat 5. The pipe pushing device 4 automatically resets after completing the pushing task, ready for the next operation. And the feeding arm 24 continues to rotate by 90 degrees (the first and second rotations add up to 180 degrees), so that the other end is repositioned to the upper area between the feeding rollers 3, fully preparing for the next round of steel pipe feeding work.

[0036] Any design of a similar technical scheme that achieves the above technical effects, whether it is the technical scheme of the present application or inspired by the technical scheme of the present application by those skilled in the art, falls within the protection scope of the present application.
