Description
Technical Field
The invention belongs to the technical field of tube drawing machinery, and particularly relates to a tube blank feeding device for a tube drawing machine, which is arranged between a machine head of the tube drawing machine and a propelling device in a use state.
Background
The foregoing tube drawing machine is mainly, but not exclusively, a seamless steel tube drawing machine. As is known in the art, a tube drawing system is generally composed of a tube drawing machine as a main machine, a pushing device for pushing a steel tube, and a tube blank feeding device located between a head of the tube drawing machine and the pushing device, and is also generally equipped with a stock storage device. When the pipe drawing machine works, the pipe storage device supplies pipe blanks to the pipe blank feeding device, and the pipe blanks on the pipe blank feeding device are propelled to the pipe drawing machine by the propelling device.
Technical information of tube blank feeding devices is seen in the published chinese patent literature, and a typical "one feeding device" as recommended by CN101628302B and a "blooming tube blank feeder" as provided by CN103157676a are not limited to the common feature of the exemplified patents that a pushing device and a feeding device are shared by each time a tube blank fed by a stock device such as a stock table or a stock frame is pushed by the pushing device toward a tube drawing machine, and the aforementioned stock device which is matched with such a patent is usually provided corresponding to one side in the longitudinal direction of the tube blank feeding device, and the tube blank is pulled toward the tube drawing machine by a reciprocating trolley of the structural system of the pushing device.
In recent years, the tube drawing efficiency of tube drawing machines is continuously improved, and simultaneous drawing of a plurality of tube blanks at one time does not have any technical obstacle and is generally accepted by seamless steel tube manufacturers. However, if the conventional art discloses the structures of CN101628302B, CN103157676a, CN201214122Y (automatic steel bar feeder), CN102762755U (a tube drawing machine using aluminum alloy processing), etc., it is difficult to simultaneously handle the drawing and feeding of plural tube blanks by one drawing trolley because the drawing trolley is used as the pushing device, and the use of plural drawing trolleys causes the problem of mutual interference, which also increases the equipment cost significantly. The method has the advantages that the pipe blanks are pushed to the pipe drawing machine by utilizing the cylinders or the oil cylinders with the same quantity as the pipe blanks at the positions corresponding to the ends of the pipe blank feeding devices far away from the pipe drawing machine, so that a good scheme is achieved. However, the problem is that: the foregoing stock device such as a stock table or a stock frame located on one side in the longitudinal direction of the pipe blank feeding device is troublesome in feeding the pipe blank to the pipe blank feeding device because the prior art has a stock device provided on one side in the longitudinal direction of the pipe blank feeding device for feeding one branch pipe blank at a time, and the feeding manner is a natural rolling of a saving type. Therefore, the feeding of the tube blanks is manually interfered or participated by the on-line operators, so that the labor intensity of the on-line operators is greatly increased. The tube blank feeding device is arranged above the tube drawing machine, that is, the tube blank feeding device is arranged in a state of being emptied above the tube drawing machine, and a tube blank can be conveniently fed to the tube blank feeding device in a cylinder or cylinder pushing mode, however, due to the fact that a drop (height difference) exists between the tube blank feeding device arranged above the tube drawing machine and a machine head inlet of the tube drawing machine, namely, the tube blank inlet, specifically, only the tube blank feeding device can be lifted or swung according to requirements between the height differences of the tube blank feeding device and the machine head inlet, the tube blank feeding device can meet the requirements of receiving materials from the tube blank feeding device and feeding the tube blank into the machine head inlet, and no reference technology is found in patent and non-patent documents disclosed so far. The applicant has made a permanent and advantageous design for this purpose and developed the solution to be described below.

In the process that the right ends of the front and rear stringers 21, 22 of the tube blank receiving frame are raised upward by the front and rear cylinder columns 531, 541 via the stringer pad 25, the front and rear rail fixing trailing arms 65, 68 of the structural system of the tube blank receiving frame lifting slide guide mechanism 6 are respectively displaced upward by the front and rear rails 63, 67 under the guidance of the front and rear rail sliders 64A, 64b, and vice versa.
Application example:
please refer to fig. 3 in combination with fig. 1 and 2, as can be seen from the schematic diagrams of fig. 2 and 3: the invention is arranged between the tube drawing machine 7 and the propelling device 9 in practice, and in fig. 3 a storage device 10 is also shown above the tube drawing machine 7, which storage device 10 may also be called a storage platform or a storage rack.
When the pipe blank 8 on the storage device 10 is to be supplied to the pipe blank feeding device of the present invention, the pipe blank 8 is pushed to the pipe blank placing beam 3 by a feed cylinder of the structural system of the storage device 10, specifically: the tube blank 8 from the stock device 10 enters, i.e., is introduced into the tube blank holding beam groove 31 of the tube blank holding beam 3 via the guide pulley 42 of the tube blank guide pulley mechanism 4. Since the tube drawing machine 7 is a three-tube drawing machine, there are three feed cylinders of the stock device, and three tube blanks 8 are pushed into the tube blank holding beam grooves 31. Then, the front and rear hydraulic cylinders 53, 54 are operated by the operation of the hydraulic station 52 of the structure system of the tube stock or the lowering driving mechanism 5 in the reverse process, the front and rear hydraulic cylinder columns 531, 541 are retracted into the cylinder, i.e., are displaced downward, so that the right end of the entire tube stock receiving frame 2 is gradually swung down from the previously raised state to the horizontal state, the right end of the tube stock 8 on the tube stock rest beam 3 corresponds to the head inlet (i.e., tube stock inlet) of the tube drawing machine 7, and the right end of the tube stock receiving frame front side member 21 is rested on the tube stock receiving frame front side member vibration damping buffer 121, and the right end of the tube stock receiving frame rear side member 22 is rested on the tube stock receiving frame rear side member vibration damping buffer 131. Then, the pushing device 9 is operated, and the tube blank pushing cylinder columns 911 of the three tube blank pushing cylinders 91 of the structure of the pushing device 9 apply pushing forces to the left end portions of the three tube blanks 8, respectively, so that the tube blanks 8 are pushed toward the head inlet as the tube blank pushing cylinder columns 911 are extended outside the cylinder bodies.
The right end of the tube blank receiving frame 2 is raised upward and restored to the horizontal state shown in fig. 3, and the signal collector trigger 681 corresponds to the signal collector 132, specifically, when the signal collector trigger 681 corresponds to the signal collector 132, the signal collector 132 collects a signal and feeds the signal back to a PLC (programmable logic controller) to realize orderly control of actions between the mechanisms.
In summary, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the task of the invention, and faithfully honors the technical effects carried by the applicant in the technical effect column above.
