The unloading mechanism 3 includes a second bracket 31 and a storage rack 32. The upper end surface of the second bracket 31 is open and a plurality of first chains 33 staggered and distributed with the pushing plate 22 are arranged in the second bracket 31. The first chain 33 is transmission-connected with a first motor 35 arranged on the second bracket 31 and a toggle plate 34 is fixedly connected to the first chain 33 and can be exposed to the upper end surface of the second bracket 31 with the movement of the first chain 33. The transmission connection between the first chain 33 and the first motor 35 can be achieved by arranging a sprocket on the transmission shaft transmission-connected to the first motor 35. The storage rack 32 is arranged on one side of the second bracket 31 and is connected to the upper end surface of the second bracket 31 through a guide plate 36.
[0022] Specifically, the push plate 22 is slidably arranged on the first bracket 21: a first linear slide rail 25 perpendicular to the walking path of the pulling trolley 12 is fixedly connected to the lower end surface of the push plate 22, and the slide seat of the first linear slide rail 25 is fixedly arranged on the first bracket 21. Through the above structure, the stability of the push plate 22 during movement is guaranteed.
[0023] Specifically, the structure in which the drawing trolley 12 is slidably arranged on the frame 1: the frame 1 is provided with two second linear slide rails 13 parallel to the walking path of the drawing trolley 12, the drawing trolley 12 is fixedly arranged on the slide seat of the second linear slide rails 13, the upper end surface of the frame 1 is open and two second chains 14 are arranged in the frame 1 and are transmission-connected to the second motor 15 arranged on the frame 1, the transmission connection between the second chain 14 and the second motor 15 can be achieved by providing a sprocket on the transmission shaft transmission-connected to the second motor 15, and the drawing trolley 12 is fixedly connected to the second chain 14.
[0024] In the above embodiment, the seamless steel pipe that has been reduced in size at the end passes through the drawing die 11 and is clamped by the drawing trolley 12. The second motor 15 drives the second chain 14 to move and drives the drawing trolley 12 to move away from the drawing die 11. The seamless steel pipe is pulled by cooperating with the drawing die 11. When the drawing operation is about to be completed, the push cylinder 23 drives a plurality of push plates 22 to move toward the seamless steel pipe through the transmission plate 24 at the same time, so that the seamless steel pipe is placed in the push plate 22 through the opening of the push plate 22. After the drawing trolley 12 completes the drawing operation on the seamless steel pipe and releases the clamping of the seamless steel pipe, the push cylinder 23 continues to drive the push plate 22 to move toward the unloading mechanism 3, thereby driving the seamless steel pipe placed in the push plate 22 toward The unloading mechanism 3 moves to the side of the second bracket 31. At this time, the plate portion below the push plate 22 is aligned with the upper end surface of the second bracket 31. Then the first motor 35 drives the first chain 33 to move and drives the toggle block to move. During the movement, the toggle block contacts the seamless steel pipe placed in the push plate 22 and toggle the seamless steel pipe to transfer it from the push plate 22 to the upper end surface of the second bracket 31. As the toggle block continues to move, it moves toward the guide plate 36 on the upper end surface of the second bracket 31. When it moves to the higher end side of the guide plate 36, it rolls down from the upper end surface of the second bracket 31 to the guide plate 36, and rolls down along the guide plate 36 to the storage rack 32, thereby completing the unloading of the seamless steel pipe that has been drawn. Through the above structure and method, the unloading operation of the seamless steel pipe that has been drawn can be automatically realized, saving manpower, reducing production costs, and improving production efficiency.
[0025] Preferably, a clamping cylinder 26 is provided on the upper end surface of the pushing plate 22, and the output shaft of the clamping cylinder 26 extends downward into the pushing plate 22 and is fixedly connected with a clamping block 27. When the seamless steel pipe is placed in the pushing plate 22 and is pushed by the pushing plate 22, the clamping cylinder 26 drives the clamping block 27 to press against the seamless steel pipe so that the seamless steel pipe is more stably maintained in the pushing plate 22, thereby enhancing the stability of the pushing plate 22 when pushing the seamless steel pipe to the unloading mechanism 3.
[0026] Preferably, a supporting cylinder 41 with an upward output shaft is provided below the opening of the frame 1, and a supporting frame 42 is fixedly connected to the output shaft of the supporting cylinder 41, and a guide wheel 43 is rotatably provided on the supporting frame 42. After the drawing trolley 12 pulls the seamless steel pipe for drawing operation and passes over the guide wheel 43, the supporting cylinder 41 drives the supporting frame 42 and the guide wheel 43 to move upward so that the guide wheel 43 abuts against the seamless steel pipe, so that the guide wheel 43 provides support for the seamless steel pipe during the drawing operation, and when the pushing plate 22 moves toward the seamless steel pipe and places the seamless steel pipe in the pushing plate 22, the support provided by the guide wheel 43 enables the end of the seamless steel pipe to be effectively supported after it completely leaves the drawing die 11, so that the seamless steel pipe can accurately enter the pushing plate 22, and after the seamless steel pipe completely enters the pushing plate 22, the supporting cylinder 41 drives the supporting frame 42 and the guide wheel 43 to move downward and reset.
[0027] Preferably, a U-shaped guide plate 37 is provided on one side of the upper end face of the second bracket 31 close to the drawing die 11, and the guide plate 37 is inclined outward toward the end of the frame 1 to form a guide portion. When the toggle block toggles the seamless steel pipe to transfer it to the upper end face of the second bracket 31, the end of the seamless steel pipe enters the guide plate 37 under the action of the guide portion, ensuring that the position of the seamless steel pipe in its length direction is aligned with the width of the guide plate 36, thereby ensuring that the seamless steel pipe can subsequently accurately roll onto the guide plate 36 and roll onto the storage rack 32 for unloading.
[0028] Furthermore, a mounting frame 51 is provided on one side of the drawing die 11 on the upper end surface of the second bracket 31, and a laser cutter 52 is provided on the mounting frame 51. The laser emitting end of the laser cutter 52 faces downward, and a blanking port opposite to the laser emitting end of the laser cutter 52 is opened on the mounting frame 51.
[0029] In the above embodiment, when the seamless steel pipe that has completed the drawing operation moves on the upper end surface of the second bracket 31 under the movement of the toggle block, the end portion thereof that has passed through the shrinkage tube will pass under the laser cutter 52. The laser cutter 52 cuts off the end portion of the seamless steel pipe that has passed through the shrinkage tube, thereby eliminating the subsequent process of shrinking the shrinkage tube end portion of the seamless steel pipe, thereby improving the production efficiency of the seamless steel pipe.
[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
