[0023] The present invention will be further described with reference to the accompanying drawings.

[0024] like Figures 1 to 3 As shown, a straight-in wire drawing machine multi-machine rolling multi-wire device includes a straight-in wire drawing machine A, a wire rolling tensioning device A, a straight-in wire drawing machine B, a wire rolling tensioning device B, a steering device, a wire joining device, a rolling machine, a wire rolling traction machine, a wire dividing device, a wire collecting device A and a wire collecting device B. The straight-in wire drawing machine A is arranged in parallel with the straight-in wire drawing machine B, and the straight-in wire drawing machine A is used to draw the A steel wire; the A wire rolling tensioning device is arranged at the discharge end of the straight-in wire drawing machine A; the straight-in wire drawing machine B is used to draw the B steel wire; the B wire rolling tensioning device is arranged at the discharge end of the straight-in wire drawing machine B; the steering device is arranged at the discharge end of the B wire rolling tensioning device; the wire joining device is arranged on one side of the A wire rolling tensioning device and the steering device, and is used to combine the A steel wire and The B steel wires are combined together; a rolling mill is arranged at the discharge end of the wire combining device, for rolling the A steel wire and the B steel wire; a wire rolling traction machine is arranged at the discharge end of the rolling mill; a wire separating device is arranged at the discharge end of the wire rolling traction machine, for separating the A steel wire and the B steel wire after rolling; a wire collecting device is arranged at the discharge end of the wire separating device, for winding up the A steel wire; a wire collecting device is arranged at one side of the wire separating device, for winding up the B steel wire.

[0025] The straight-through wire drawing machine A comprises a wire feeding machine A and a wire drawing machine A which are arranged in sequence.

[0026] The straight-through wire drawing machine B comprises a B wire feeding machine and a B wire drawing machine which are arranged in sequence.

[0027] The wire drawing machine is used to draw a thicker steel wire multiple times to obtain a steel wire with a diameter less than 2mm. For example, a steel wire with a diameter of 6.5mm can be drawn into a steel wire with a diameter of 2mm, and a steel wire with a diameter of 3mm can be drawn into a steel wire with a diameter of 0.6mm.

[0028] The A wire collection device comprises an A wire collection tensioning device and an A winding machine which are arranged in sequence. The A wire collection tensioning device is located at the discharge end of the wire separation device.

[0029] The B wire collection device comprises a B wire collection tensioning device and a B winding machine which are arranged in sequence. The second wire collection tensioning device is located on one side of the wire separation device.

[0030] The steering device includes a bogie, a B vertical steering wheel, a B transverse steering wheel and an A transverse steering wheel. The bogie includes an A steering column, a B steering column and a steering beam, and the steering beam is fixed on the top of the A steering column and the B steering column to form a U shape. The A steering column is installed on the straight-in wire drawing machine A, and the B steering column is installed on the straight-in wire drawing machine B. The B vertical steering wheel is rotatably arranged at the bottom of the B steering column and is arranged opposite to the B wire rolling tensioning device; the B transverse steering wheel is rotatably arranged at the top of the B steering column; the A transverse steering wheel is rotatably arranged at the top of the A steering column and is arranged opposite to the B transverse steering wheel. The B steel wire tightened from the second wire rolling passes through the B vertical steering wheel, the B transverse steering wheel and the A transverse steering wheel in sequence and then enters the wire combining device. The bogie is used to pass the B steel wire from high altitude through the gap between the straight-in wire drawing machine A and the straight-in wire drawing machine B, which is convenient for maintenance and production. The structure of the wire dividing device is the same as that of the steering device, but the function is opposite.

[0031] The wire combining device includes a wire combining wheel, which is rotatably arranged at the bottom of the A steering column and is respectively arranged opposite to the A lateral steering wheel and the first wire binding and tensioning device, and is used to combine the A steel wire and the B steel wire and transport them to the rolling mill.

[0032] like Figure 2 and Figure 3As shown, the structure of the wire tensioning device A is the same as that of the wire tensioning device B. The wire tensioning device A includes: a tension frame, a tension sensor 12, a tension control rod 13, a tension sensor 12, a tension drive cylinder 11 and a tension control roller 14. The tension drive roller 15 and the tension control rod 13 are both rotatably mounted on the tension frame, the tension sensor 12 is located at one end of the tension control rod 13, and is used to detect the tension control rod 13. The tension control roller 14 is rotatably mounted on one end of the tension control rod 13 through a bearing seat and is located on one side of the tension sensor 12. The tail of the tension drive cylinder 11 is rotatably mounted on the tension frame, and the end of the piston rod is rotatably connected to the other end of the tension control rod 13. The tension drive cylinder 11 adopts a pneumatic cylinder, and can also adopt an electric cylinder. The tension sensor 12 uses a proximity switch, which can detect the tension of the steel wire in real time. When the tension sensor 12 detects the tension control rod 13, it means that the tensioning force is too small. The tension driving cylinder 11 drives the tension control roller 14 through the tension control rod 13 to move away from the tension transmission roller 15, thereby increasing the tension of the steel wire until the tension sensor 12 cannot detect the tension control rod 13. Then the tension driving cylinder 11 drives the tension control roller 14 in the opposite direction to move toward the tension transmission roller 15 until the tension sensor 12 detects the tension control rod 13. This reciprocating process realizes dynamic tension adjustment and maintains a stable tension.

[0033] Stable operation is achieved through the tension control device, the number of wire drawing machines is reduced, and efficiency is improved.

[0034] In order to improve the stability and reliability of the wire tension control, the tension transmission roller 15 is provided with an annular upper transmission groove A 141 and a lower transmission groove A 142 in sequence; the tension control roller 14 is provided with an annular upper transmission groove B 151, a middle transmission groove B 152 and a lower transmission groove B 153 in sequence; wherein, the wire enters from the upper transmission groove B 151, then enters the upper transmission groove A 141, then enters the middle transmission groove B 152 through the upper transmission groove A 141, then enters the lower transmission groove A 142 through the middle transmission groove B 152, then enters the lower transmission groove B 153 through the lower transmission groove A 142, and then leaves from the lower transmission groove B 153. Arranging multiple wires between the tension control roller 14 and the tension transmission roller 15 can not only improve the stability, but also prevent a single wire from being easily broken after being stressed, and the whole can withstand a large tensioning force.

[0035] Wire feeder A and wire feeder B release steel wire A and steel wire B respectively; then steel wire A and steel wire B are drawn by wire drawing machine A and wire drawing machine B for 10 to 11 passes respectively; the drawn steel wire A passes through wire rolling and tensioning device A and is combined with steel wire B that passes through wire rolling and tensioning device B and steering device in wire combining device and enters into rolling mill, steel wire A and steel wire B are obtained through roller die of rolling mill by wire rolling traction machine and steel wire A and steel wire B are pulled and fed into wire dividing device, steel wire A and steel wire B pass through wire dividing device and enter into wire collecting and tensioning device A and wire collecting and tensioning device B respectively, and finally are wound by winding machine A and winding machine B.

[0036] The A wire tensioning device and the B wire tensioning device control the A steel wire and the B steel wire after the wire joining to enter the roller die with the same tension, otherwise the steel wire will easily break.

[0037] For steel wires of different cross-sections rolled by multiple machines, since the compression ratios of steel wires of different cross-sections are different, adjustments must be made in the die cavity design. Taking triangles and semicircles as examples, the length of the bottom side of the rolled triangle relative to the diameter of the semicircle is close to the diameter of the semicircular steel wire.

[0038] A traction machine can be arranged between the A wire drawing machine and the A wire rolling and tensioning device, and a traction machine can be arranged between the B wire drawing machine and the B wire rolling and tensioning device.

[0039] The use of a straight-feed wire drawing machine with multiple wires and multiple rolling processes can improve the stability of the rolled steel wire and reduce the number of rolling mills. The use of a straight-feed wire drawing machine with multiple wires and multiple rolling processes can realize the rolling of steel wires with multiple different cross-sections by multiple machines, such as simultaneously rolling steel wires with triangular and semicircular cross-sections.

[0040] like Figure 1 As shown, a wire-binding method for a multi-wire rolling device of a straight-through wire drawing machine comprises the following steps:

[0041] A steel wire and B steel wire are drawn by a straight-feed wire drawing machine A and a straight-feed wire drawing machine B respectively;

[0042] The A wire tensioning device and the B wire tensioning device are used to maintain the same conveying speed of the A steel wire and the B steel wire;

[0043] The A steel wire and the B steel wire are combined together by a steering device and a wire combining device;

[0044] The A steel wire and the B steel wire are pulled through the wire rolling mill by the wire rolling traction machine;

[0045] Separating the rolled A steel wire and B steel wire by a wire separation device;

[0046] The A wire collection device and the B wire collection device are used to respectively reel in the A steel wire and the B steel wire.

[0047] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the protection scope of the claims of the present invention.
