Description

Technical Field

[0001] The utility model relates to the technical field of pipe production and processing, in particular to a material discharge stabilizing device and pipe drawing equipment. Background Art

[0002] At present, in the production of pipes, a certain length of ingot is milled to remove the surface oxide scale, and then enters the pipe rolling mill for ingot rolling. After the pipe rolling is completed, the pipe is coiled into a coil, and then the pipe is drawn, so that the pipe with the required outer diameter and wall thickness can be obtained. Before drawing, the pipe needs to be headed to form a flatter pipe head, so that the drawing machine can clamp the pipe head of the pipe and then draw it. During the drawing, the coiled pipe needs to be placed on the material frame and then unloaded. After unloading, the pipe passes through the straightening device and then enters the drawing mechanism.

[0003] The straightening device usually includes a bracket and multiple groups of straightening wheels arranged on the bracket, each group includes two straightening wheels arranged opposite to each other. Since the material frame is not at the same height as the straightening device, the material frame is usually lower than the straightening device, causing the pipe to tilt upward, which causes the pipe to jump up and down during high-speed drawing and unloading, causing the first group of straightening wheels of the straightening device to be subjected to great force. When the pipe jumps too much, it will jump out of the straightening wheel, which can easily cause the pipe to bend and break, affecting production. Utility Model Content

[0029] See also Figure 1 An embodiment of the utility model provides a material discharging stabilizing device, including: a mounting seat 10, a rotating arm 20 and a rotating driving assembly 30.

[0030] The rotating arm 20 is rotatably arranged on the mounting seat 10, and the rotating driving assembly 30 is drivingly connected to the rotating arm 20, and is used to drive the rotating arm 20 to rotate relative to the mounting seat 10. A stopper 40 is arranged between the rotating arm 20 and the mounting seat 10. After the rotating driving assembly 30 drives the rotating arm 20 to rotate toward the mounting seat 10, the rotating arm 20, the stopper 40 and the mounting seat 10 surround and form a pipe limiting space 50. The position of the pipe is limited by the pipe limiting space 50, so that the jumping amplitude of the pipe is effectively limited when the pipe is discharged, and the failure rate of the straightening device is reduced. When the pipe needs to be pulled, the rotating arm 20 is rotated away from the mounting seat 10, and the pipe can be placed between the rotating arm 20, the stopper 40 and the mounting seat 10, and then the rotating arm 20 is rotated toward the mounting seat 10, so that the rotating arm 20, the stopper 40 and the mounting seat 10 cooperate to form the pipe limiting space 50 again to limit the jumping amplitude of the pipe.

[0031] In some optional embodiments, a stopper 40 is disposed on the mounting base 10, and a positioning slot 41 is provided on the stopper 40. After the rotary drive assembly 30 drives the rotating arm 20 to rotate toward the mounting base 10, the rotating arm 20 is positioned and matched with the positioning slot 41, thereby limiting the position of the rotating arm 20 and preventing the rotating arm 20 from being pushed away from the mounting base 10 due to the jumping of the pipe, resulting in the pipe restriction space 50 being released and the pipe being free from the restriction.

[0032] See also Figure 2In some optional embodiments, a roller 21 is rotatably provided on the rotating arm 20, and the tube is constantly moved during the drawing process, and the roller 21 can be rolled to generate rolling friction with less friction between the tube and the roller 21, thereby avoiding scratches or abrasions on the surface of the tube and improving product quality. Preferably, the roller 21 is made of nylon, which has a relatively small friction coefficient, and can avoid scratches or abrasions on the surface of the tube as much as possible.

[0033] In addition, in order to improve the stability of the drum 21 , a plurality of bearings 25 are provided between the drum 21 and the rotating arm 20 .

[0034] In some optional embodiments, the rotating arm 20 includes a base portion 22 and a rotating shaft portion 23. The base portion 22 is rotationally matched with the mounting seat 10, and the roller 21 is rotationally matched with the rotating shaft portion 23, thereby facilitating the installation of the roller 21. After the rotating drive assembly 30 drives the rotating arm 20 to rotate toward the mounting seat 10, the rotating shaft portion 23 is inserted into the positioning slot 41.

[0035] See also Figure 3 In some optional embodiments, the mounting seat 10 is provided with a shaft seat 11, the shaft seat 11 and the stopper 40 are respectively located at both ends of the rotating arm 20, and the rotating arm 20 and the shaft seat 11 are rotated in cooperation; after the rotating drive assembly 30 drives the rotating arm 20 to rotate toward the mounting seat 10, the rotating arm 20, the stopper 40, the mounting seat 10 and the shaft seat 11 surround and form a pipe limiting space 50. The design of the shaft seat 11 not only facilitates the spacing of a certain distance between the rotating arm 20 and the mounting seat 10, which is convenient for the pipe to pass through, but also facilitates the formation of the pipe limiting space 50.

[0036] In some optional embodiments, a rotating shaft sleeve 24 is provided on the rotating arm 20, and the rotating shaft sleeve 24 is sleeved on the outer side of the rotating shaft seat 11. The rotating arm 20 rotates with the rotating shaft seat 11 through the rotating shaft sleeve 24, so that the rotating arm 20 can stably rotate relative to the rotating shaft seat 11, thereby improving the stability of the rotating arm 20.

[0037] See also Figure 4 The specific structure of the rotary drive assembly 30 can be designed according to actual needs. For example, in some optional embodiments, the rotary drive assembly 30 includes a driving cylinder 31, and the output shaft of the driving cylinder 31 is rotatably connected to the swing arm 20. When the output shaft of the driving cylinder 31 is extended or retracted, it can push the swing arm 20 to rotate relative to the mounting seat 10. In this embodiment, the output shaft of the driving cylinder 31 is connected to the shaft sleeve 24. Of course, the rotary drive assembly 30 can also adopt a hydraulic cylinder or an electric cylinder, and the output shaft of the hydraulic cylinder or the electric cylinder is rotatably connected to the swing arm 20; or, the rotary drive assembly 30 can also adopt a driving motor, and the output shaft of the driving motor is drivingly connected to the swing arm 20.

[0038] In order to facilitate the installation of the driving cylinder 31, in some optional embodiments, the rotation drive assembly 30 further includes a cylinder fixing seat 32, and the driving cylinder 31 is installed on the cylinder fixing seat 32. In this embodiment, the cylinder fixing seat 32 and the mounting seat 10 are both arranged on the bracket of the correction device. Of course, the cylinder fixing seat 32 and the mounting seat 10 can also select other suitable installation positions according to the actual production environment, and are not limited to this example.

[0039] In some optional embodiments, a movable seat 33 is provided on the driving cylinder 31, and a movable groove 34 is provided on the cylinder fixing seat 32. The movable seat 33 extends into the movable groove 34 and rotates with the inner wall of the movable groove 34, thereby reducing structural interference when the driving cylinder 31 drives the rotating arm 20 to rotate. The design of the movable groove 34 and the movable seat 33 enables the driving cylinder 31 to rotate stably relative to the cylinder fixing seat 32, thereby improving the structural stability.

[0040] The above-mentioned material discharge stabilization device can be applied to a pipe drawing device, which includes: a straightening device, a drawing mechanism, and a material discharge stabilization device as described above, wherein the material discharge stabilization device, the straightening device, and the drawing mechanism are arranged in sequence. In this embodiment, the mounting seat 10 and the cylinder fixing seat 32 of the material discharge stabilization device are arranged on the straightening device. During drawing, the pipe passes through the pipe limiting space 50, the straightening device, and the drawing mechanism in sequence. The structure and principle of the straightening device and the drawing mechanism are well known to those skilled in the art, and will not be described in detail here.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
