Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel pipe processing equipment, in particular to a turning, rolling and rotating tooling structure for steel pipes between a pipe rack and a roller rack. Background Art
[0002] When designing an automated production line for lined composite steel pipes, each pipe (such as a steel pipe) needs to undergo end processing, such as pre-processing, post-processing, welding, sizing, and other processes. In order to buffer the processes, a steel pipe rack is provided between each process. The pipes processed in the previous process must be stored on the rack and wait for the next process to be processed. Since each process requires a different amount of time, a pipe rack needs to be set up for buffering. When entering the process, the pipes on the rack need to be moved down. The pipes that have been moved down need to be moved longitudinally because the distance between the pipe end and the processing machine tool is inconsistent. During the processing, the steel pipe needs to be rotated and supported during rotation. After the process is completed, the steel pipe needs to be longitudinally moved out of the spindle hole of the machine tool, and the pipe needs to be moved to the other side of the rack. To complete these actions, a set of devices needs to be designed to achieve this. Utility Model Content

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0017] See also Figure 1-3 The utility model discloses a turning, rolling and rotating tooling structure for steel pipes between a pipe rack and a roller rack. As shown in the figure: it is arranged between two adjacent rows of pipe racks 8 of a steel pipe 3 production line; it comprises a cylinder 1 (usually fixed on a cylinder support 2), the telescopic rod of the cylinder 1 is connected to a flap linkage rod 5 in the same extension direction as the steel pipe 3; the flap linkage rod 5 is connected to a plurality of flaps 4 that move synchronously in the extension direction of the steel pipe 3; the flap linkage rod 5 is connected to one end of a plurality of connecting rods 9, the other ends of the plurality of connecting rods 9 are connected to a rotating shaft 10, and the rotating shaft 10 is connected to a plurality of flaps 4 through a connecting member 11; the upper end of the flap 4 has a first inclined portion 41 and a second inclined portion 42, and a step portion 43 is formed between the lower end of the first inclined portion 41 and the upper end of the second inclined portion 42; a roller rack is arranged between two adjacent rows of pipe racks 8.
[0018] In the utility model, the roller frame includes a longitudinal moving roller frame 6 for moving the steel pipe 3 longitudinally and a rotating roller frame 7 for rotating the steel pipe 3 .
[0019] In the present invention, since the steel pipe 2 is usually long, the number of the synchronously moving flaps 4 is more than 3 (such as 3-4), which is beneficial for uniformly supporting the force of the steel pipe 2 during the station transfer process.
[0020] During use of the utility model, Figure 4 , 5 As shown in the figure: the steel pipe 3 is first located at position a on the first pipe rack; when the cylinder 1 drives the connecting rod 9 through the flap linkage pull rod 5, the other end of the connecting rod 9 drives the flap 4 to rotate through the rotating shaft 10 connected thereto, and the flap 4 rotates to lift the steel pipe 3 from position a to position b (i.e., the high end of the first inclined portion 41); the steel pipe 3 moves from the high end of the first inclined portion 41 to the step portion 43 (i.e., position c) by gravity; the cylinder 1 then drives the flap 4 to rotate, at which time the upper end of the flap 4 is lowered, and the steel pipe 3 just falls between the rollers of the longitudinal moving roller frame 6 and the rotating roller frame 7 and is located at position d; through the longitudinal moving roller frame 6 and the rotating roller frame 7 The rotating roller frame 7 cooperates with the processing machine tool to perform certain processing on the steel pipe 3; when the processing is completed, the cylinder 1 drives the connecting rod 9 again through the flap linkage pull rod 5, and the other end of the connecting rod 9 drives the flap 4 to rotate through the rotating shaft 10 connected to it. After the flap 4 rotates, the steel pipe 3 is lifted from the d position to the e position (that is, the high end of the second inclined portion 42); the steel pipe 3 moves from the high end of the second inclined portion 42 to the low end f position of the second inclined portion 42 by gravity, and finally moves to the g position on the next pipe rack; finally, the cylinder 1 drives the flap 4 to rotate again, and at this time the upper end of the flap 4 is lowered again, so that the next turnover movement of the steel pipe 3 can be carried out.
[0021] The utility model is adopted to transfer steel pipes between a pipe rack, a processing position and a next pipe rack. The utility model has a simple structure and high efficiency and is applicable to a wide range of steel pipe diameters (pipe diameters are 88.9-914mm).
