Description

Technical Field

[0002] In daily life, sometimes we need to use metal wires to bind some objects. Since metal wires are too thin and easy to break, and there are no other specifications of metal wires, we usually twist two or more metal wires together to improve the toughness and strength of the overall metal wires to a certain extent. When performing rotary wire twisting operations, we usually choose to use simple clamps or vises. When rotating and winding multiple metal wires, we not only need to clamp multiple metal wires, but also provide rotational torque. The more wires are wound, the greater the clamping force required. The torque is sometimes difficult to control, resulting in loose, uneven, and bent wires. The overall operation is time-consuming and laborious. Summary of the invention

[0010] A method for using a wire twisting device for twisting a plurality of metal filaments, specifically comprising the following steps:

[0011] (1) Adjust the distance between the screw thread slide and the screw loading platform through the transverse movement mechanism, and lock the screw thread slide;

[0012] (2) Install the reel with the wound metal filaments onto the reel on the top of the wire loading platform, pull one end of the metal filaments out of the reel, and wind the metal filaments between the rectangular cover plate and the wire twisting disk for n turns, where n ≥ 1, and then clamp the wound metal filaments through the wire clamping mechanism;

[0013] (3) Tighten multiple metal filaments together through a wire twisting mechanism to complete the wire twisting operation;

[0014] (4) After the wire twisting is completed, cut off the metal filaments connected to the reel, loosen the wire clamping mechanism, and remove the multiple metal filaments that have been twisted into a rope.

[0015] Step (1) is specifically as follows: first, the operator loosens the two locking bolts, and then rotates the first turntable wheel through the first crank handle. The first turntable wheel drives the lead screw to rotate. The lead screw passes through the first threaded hole on the thread-twisting slide and is threadedly connected. The lead screw drives the thread-twisting slide to move forward and backward along the two horizontal guide rails. The distance between the thread-twisting slide and the thread-loading platform is adjusted according to the length of the metal wire to be tightened, so that the distance between the thread-twisting slide and the thread-loading platform is equivalent to the length of the metal wire to be tightened. After that, the two locking bolts are tightened so that the inner ends of the two locking bolts are respectively pressed into the two locking long grooves to lock and fix the thread-twisting slide.

[0016] Step (2) specifically comprises: pulling one end of the metal filament out of the reel and passing it forward through the wire threading channel groove in the middle of the block, and then passing it forward through the first wire threading opening in the middle of the side of the rectangular cover plate, and then pulling the metal filament forward and passing it through a certain T-shaped winding long hole on the wire twisting disk, and then passing it through a radially symmetrical T-shaped winding long hole through 180 degrees, and passing it backward through the second wire threading opening in the middle of the side of the rectangular cover plate, so that after one circle of the metal filament, two metal filaments are arranged side by side;

[0017] When four metal wires need to be twisted, continue to pass one end of the metal wire forward through the first threading hole in the middle of the side of the rectangular cover plate, then pass the metal wire through a T-shaped winding long hole on the twisting disk, then go around 180° and pass through a radially symmetrical T-shaped winding long hole, and then pass through the second threading hole in the middle of the side of the rectangular cover plate backwards;

[0018] According to the number of metal filaments to be twisted, the above operation is repeated, and the metal filaments can be wound n times between the rectangular cover plate and the twisting disc, where n≥1;

[0019] When the number of metal filaments to be twisted is an odd number, it is only necessary to finally pass the metal filaments through the second threading opening in the middle of the side of the rectangular cover plate without going backwards;

[0020] After the metal filament is wound, the metal filament is tightened and one end of the metal filament is tied to the hanging ring so that the metal filament is in a tensioned state as a whole, and then the semi-cylindrical block of the wire clamping mechanism is pressed downward so that the left and right side plates of the clamping block are respectively clamped in the two wire threading ports. Moreover, under the action of the top pressure spring, the semi-circular arc push plate presses the semi-cylindrical block forward so that the trapezoidal boss and the inclined surface move downward in coordination and are correspondingly clamped in the rectangular clamping hole in the middle of the rectangular cover plate, and the return spring is compressed. In this way, the clamping block can clamp the metal filament wound around the two wire threading ports to prevent the metal filament from slipping out of the wire threading ports.

[0021] Step (3) is specifically as follows: the operator rotates the second turntable wheel through the second crank handle, and the second turntable wheel drives the wire twisting disk to rotate, and the wire twisting disk drives the multiple metal filaments wound between the rectangular cover plate and the wire twisting disk to rotate and twist together until the multiple metal filaments are twisted into a rope, thus completing the wire twisting operation.

[0022] Step (4) is specifically as follows: the operator first uses special scissors to cut the metal filaments connected to the reel, and then presses the trapezoidal boss backwards to push the trapezoidal boss out of the rectangular clamping hole in the middle of the rectangular cover plate. After that, the return spring returns upward to push up the vertical cylinder, thereby pushing the clamping block out of the two threading ports. In this way, the multiple metal filaments that have been twisted into a rope can be removed.

[0023] The present invention has outstanding substantial features and significant progress compared to the prior art. Specifically, the present invention has a simple structure and is easy to operate. It can twist a plurality of metal filaments together to enhance the toughness and strength of the overall metal filaments. The wire twisting operation is labor-saving and easy to control, so that the twisted plurality of metal filaments are tight and uniform without wire bending. BRIEF DESCRIPTION OF THE DRAWINGS

The lead screw 27 drives the thread-twisting slide 2 to move back and forth along the two horizontal guide rails 4. The distance between the thread-twisting slide 2 and the thread-loading platform 5 is adjusted according to the length of the metal filament to be tightened, so that the distance between the thread-twisting slide 2 and the thread-loading platform 5 is equivalent to the length of the metal filament to be tightened. Thereafter, the two locking bolts 37 are tightened so that the inner ends of the two locking bolts 37 are respectively pressed against the two locking long grooves 36 to lock and fix the thread-twisting slide 2.

[0046] Step (2) specifically comprises: pulling one end of the metal filament out of the reel 7 and passing it forward through the wire threading channel groove 25 in the middle of the clamping block 24, and then passing it forward through the first wire threading opening 12 in the middle of the upper side of the rectangular cover plate 10, and then pulling the metal filament forward and passing it through a certain T-shaped winding long hole 48 on the wire twisting disk 39, and then passing it through a radially symmetrical T-shaped winding long hole 48 through 180 degrees, and passing it backward through the second wire threading opening 12 in the middle of the upper side of the rectangular cover plate 10, so that the metal filament is wound once and two metal filaments are arranged side by side;

[0047] When four metal filaments need to be twisted, continue to pass one end of the metal filament forward through the first threading opening 12 in the middle of the upper side of the rectangular cover plate 10, then pass the metal filament through a certain T-shaped winding long hole 48 on the twisting disk 39, then go around 180° and pass through a radially symmetrical T-shaped winding long hole 48, and then pass through the second threading opening 12 in the middle of the upper side of the rectangular cover plate 10 backward;

[0048] According to the number of metal filaments to be twisted, the above operation is repeated, and the metal filaments can be wound n times between the rectangular cover plate 10 and the twisting disk 39, where n≥1;

[0049] When the number of metal filaments to be twisted is an odd number, it is only necessary to finally pass the metal filaments through the second threading opening in the middle of the upper side of the rectangular cover plate 10 without going backwards;

[0050] After the metal filament is wound, the metal filament is tightened and one end of the metal filament is tied to the hanging ring 54 so that the metal filament is in a tensioned state as a whole. Then, the semi-cylindrical block 17 of the wire-clamping mechanism is pressed downward so that the left and right side plates of the clamping block 24 are respectively clamped in the two wire-threading ports 12. Moreover, under the action of the pressing spring 15, the semi-circular arc push plate 16 presses the semi-cylindrical block 17 forward so that the trapezoidal boss 23 cooperates with the inclined surface 53 to move downward and correspondingly clamp in the rectangular clamping hole 11 in the middle of the rectangular cover plate 10. The return spring 14 is compressed. In this way, the clamping block 24 can clamp the metal filament wound around the two wire-threading ports 12 to prevent the metal filament from slipping out of the wire-threading ports 12.

[0051] Step (3) is specifically as follows: the operator rotates the second turntable wheel 40 through the second crank handle 49, and the second turntable wheel 40 drives the screw thread disc 39 to rotate, and the screw thread disc 39 drives the multiple metal filaments wound between the rectangular cover plate 10 and the screw thread disc 39 to rotate and screw together until the multiple metal filaments are screwed into a rope, thus completing the screw thread operation.

[0052] Step (4) is as follows: the operator first uses special scissors to cut the metal filaments connected to the reel 7, and then presses the trapezoidal boss 23 backward to push the trapezoidal boss 23 out of the rectangular clamping hole 11 in the middle of the rectangular cover plate 10. After that, the return spring 14 returns upward to push up the vertical cylinder 13, thereby pushing the clamping block 24 out of the two threading ports 12. In this way, the multiple metal filaments that have been twisted into a rope can be removed.
