Description

Tube billet feeding device for tube drawing machine

technical field

The utility model belongs to the technical field of pipe drawing machines, in particular to a tube billet feeding device for a pipe drawing machine, which is arranged between the head of the pipe drawing machine and a propulsion device in a state of use.

Background technique

The aforementioned pipe drawing machine mainly refers to, but is not absolutely limited to, the seamless steel pipe drawing machine. As known in the industry, a complete pipe drawing system usually consists of a pipe drawing machine as the main machine, a propulsion device for advancing the steel pipe, and a tube billet feeding device between the head of the pipe drawing machine and the propulsion device. In addition, it is usually equipped with a storage device. When working, the storage device provides the tube blank to the tube blank feeding device, and the propulsion device pushes the tube blank on the tube blank feeding device to the tube drawing machine.

The technical information of various tube billet feeding devices can be seen in the published Chinese patent documents, typically such as "a kind of feeding device" recommended by CN101628302B and "opening billet tube billet feeder" provided by CN103157676A, not limited to examples The common feature of these patents is that the propulsion device and the feeding device share a mechanism, each time a pipe blank supplied by the storage device such as a storage platform or a storage rack is pushed from the propulsion device to the pipe drawing machine, and with this type The above-mentioned storage device matched with the patent is usually set corresponding to one side of the long side direction of the tube billet feeding device, and the reciprocating moving trolley of the structural system of the propulsion device pulls the billet tube towards the direction of the tube drawing machine.

In recent years, the tube drawing efficiency of the tube drawing machine has been continuously improved, and there is no technical obstacle in drawing multiple tube blanks at the same time, and it has been generally accepted by seamless steel pipe manufacturers.

Therefore, the feeding of the plurality of tube blanks needs to be manually intervened or participated by the online operators, thus greatly increasing the labor intensity of the online operators. The storage device is set above the pipe drawing machine, that is to say, the storage device is set in the state of vacating above the pipe drawing machine, and the tube blank can be conveniently fed to the tube blank feeding device by means of oil cylinder or air cylinder push, but , because there is a drop (height difference) between the storage device above the pipe drawing machine and the entrance of the pipe blank of the pipe drawing machine, that is, the entrance of the pipe blank. The height difference needs to be raised or lowered or called swinging, so that the tube blank feeding device can meet the requirements of receiving material from the storage device and feeding material to the inlet of the machine head.

Retraction in the body means downward displacement, driving the right end of the entire tube blank receiving frame 2 to gradually swing down from the previous raised state to a horizontal state, so that the right end of the tube blank 8 on the tube blank resting beam 3 and the tube drawing machine 7 Corresponding to the entrance of the machine head (that is, the entrance of the tube blank), and the right end of the front longitudinal beam 21 of the tube blank receiving frame rests on the aforementioned vibration damping and buffering device 121 of the front longitudinal beam of the tube blank receiving frame, and the tube blank receiving frame The right end of the rear longitudinal beam 22 rests on the rear longitudinal beam damping and buffering device 131 of the aforementioned tube billet receiving frame. Then, the aforesaid propulsion device 9 works, and the tube billet propulsion cylinder columns 911 of the three billet billet propulsion cylinders 91 of the structural system of the propulsion device 9 respectively apply thrust to the left ends of the three billet pipes 8. The extension of the blank pushing cylinder column 911 to the outside of the cylinder pushes the tube blank 8 towards the entrance of the aforementioned machine head.

The right end of the aforementioned tube billet receiving frame 2 lifts up and returns to the horizontal state shown in FIG. When corresponding to the signal collector 132, the signal collector 132 collects the signal and feeds the signal back to the PLC (programmable logic controller), so as to realize the orderly control of the actions among the various mechanisms.

In summary, the technical solution provided by the utility model makes up for the shortcomings in the prior art, successfully completes the invention task, and faithfully fulfills the technical effect described by the applicant in the above technical effect column.
