Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing machines, in particular to a direct-feed wire drawing machine directly driven by a permanent magnet synchronous motor. Background Art

[0002] The straight-in wire drawing machine is one of the common metal wire processing equipment. The straight-in wire drawing machine can draw high, medium and low carbon steel wire, stainless steel wire, copper wire, alloy copper wire and aluminum alloy wire, etc. It is deeply loved by users for its high speed of finished metal wire, stable drawing, small deformation of steel wire, low wire breakage rate and low equipment failure rate. The permanent magnet synchronous motor provides excitation with permanent magnets, which makes the motor structure simpler, reduces the processing and assembly costs, and eliminates the collector rings and brushes that are prone to problems, thereby improving the reliability of the motor operation. At present, the traditional straight-in wire drawing machine is usually driven by a permanent magnet synchronous motor, which does not require excitation current and has no excitation loss, thereby improving the efficiency of the straight-in wire drawing machine.

[0003] When loading materials, traditional straight-in wire drawing machines usually only have one loading tray, and the wire is placed on the unwinding drum, and then placed on the loading tray for loading. This results in the need for additional preparations during subsequent loading, which slows down the loading of the wire coil and takes a long time. At the same time, some columns on the loading tray cannot position the unwinding drum well, which results in the unwinding drum not being able to rotate well when rotating, resulting in material stripping during loading.

The bottom of the column 2 is fixedly provided with a rotating block 22, and the bottom of the rotating block 22 extends into the slide slot 21. The end of the rotating block 22 located in the slide slot 21 is fixedly provided with a first gear 23. The end of the loading tray 11 close to the wire drawing machine body 1 is fixedly provided with a mounting plate 24. A second gear 25 meshing with the first gear 23 is rotatably provided in the mounting plate 24. A second motor 26 is installed on the upper surface of the mounting plate 24 close to the second gear 25. The output end of the second motor 26 is coaxially fixed at the center of the second gear 25. The side wall of the loading tray 11 is fixedly provided with a first motor 18, and a connecting component is provided between the output end of the first motor 18 and the rotating rod 13.

[0022] The connecting component includes a groove 14, which is opened at the center of the loading tray 11 and the bottom of the rotating rod 13 is rotatably set in the groove 14. The rotating rod 13 is located in the groove 14 and a worm gear 15 is fixed at one end. A horizontally set connecting shaft 17 is rotatably provided in the groove 14. The connecting shaft 17 is located in the groove 14 and a worm 16 meshing with the worm gear 15 is fixed at one end. The output end of the first motor 18 is coaxially fixed on the connecting rod 34.

[0023] By adopting the above technical solution, the worm 16 is arranged to drive the worm wheel 15 to drive the rotating rod 13 to rotate, so as to prevent the rotating plate 12 driven by the first motor 18 from reversing, causing the position of the placement column 2 to shift and affecting the wire drawing.

[0024] A movable plate 27 is fixedly provided at one end of the placement column 2 that passes through the rotating plate 12 , and the movable plate 27 is rotatably arranged in the rotating plate 12 .

[0025] By adopting the above technical solution, the movable plate 27 can make the placement column 2 stably set on the rotating plate 12, and the placement column 2 can also stably rotate on the rotating plate 12.

[0026] The driving assembly includes a screw rod 31, which is vertically arranged and has threads at both ends arranged oppositely. The upper and lower ends of the screw rod 31 are rotatably arranged on the upper and lower side walls of the inner wall of the placing column 2. Moving blocks 311 are threadedly inserted at both ends of the screw rod 31. Push rods 32 are rotatably arranged on the two opposite sides of the moving block 311. Two symmetrically distributed top plates 33 are arranged inside the placing column 2. One end of the push rod 32 away from the moving block 311 is rotatably arranged on the top plate 33.

The end of the connecting rod 34 away from the top plate 33 passes through the placing column 2 and is fixedly arranged on the positioning plate 3.

[0027] By adopting the above technical solution, when the screw rod 31 rotates, the moving blocks 311 at both ends will move toward each other. At this time, the moving block 311 will push the top plate 33 through the top rod 32 to drive the two positioning plates 3 to move backwards at the same time, so as to position the inner wall of the unwinding drum mounted on the placing column 2, so that the unwinding drum can be stably set on the placing column 2, avoiding the unwinding drum from detaching during rotation, resulting in the iron wire cannot be unwound normally during unwinding.

[0028] A third motor 35 is installed on the upper surface of the outer wall of the placement column 2 , and an output end of the third motor 35 is coaxially fixed on the screw rod 31 .

[0029] By adopting the above technical solution, the third motor 35 can automatically drive the screw rod 31 to rotate, which is convenient for the staff to operate.

[0030] Limit rods 36 are movably inserted at the upper and lower ends of the top plate 33 , and both ends of the limit rods 36 are fixedly arranged on the inner wall of the placement column 2 .

[0032] A support plate 37 is fixedly provided above the outer wall of the placement column 2 .

[0033] By adopting the above technical solution, the support plate 37 is used to place the unwinding drum to be placed so that it can be stably placed on the placement column 2.

[0034] Working principle: when in use, the staff can sleeve the unwinding drum for placing the wire wire on the placing column 2 on the loading disk 11, and the third motor 35 can drive the screw rod 31 to rotate, so that the moving blocks 311 threadedly inserted at both ends of the screw rod 31 will move toward each other, at this time, the top rod 32 hingedly arranged between the moving block 311 and the top plate 33 will gradually move to a vertical state, at this time, the top rod 32 will push the top plate 33 to move toward the positioning plate 3, and the positioning plate 3 and the top plate 33 are fixedly connected by the connecting rod 34. At this time, the connecting rod 34 will push the positioning plate 3 to move away from the placing column 2, so that the two positioning plates 3 on one placing column 2 move back to back at the same time, and position the inner wall of the unwinding drum sleeved on the placing column 2, so that the unwinding drum can be stably set on the placing column 2, to prevent the unwinding drum from detaching during rotation, resulting in the failure of the wire to be unwound normally during unwinding;

[0035] When unwinding is required, the second motor 26 can drive the second gear 25 to rotate, so that the second gear 25 drives the first gear 23 to rotate, so that the first gear 23 drives the rotating block 22 to drive the placement column 2 to rotate, so that the placement column 2 drives the positioned unwinding drum to rotate, thereby performing the unwinding operation;

[0036] When all the iron wires on one of the unwinding drums are drawn, the second motor 26 stops working, and the working first motor 18 can drive the connecting shaft 17 to rotate. The connecting shaft 17 will drive the worm wheel 15 to rotate through the worm 16, so that the worm wheel 15 drives the rotating rod 13 to rotate. At this time, the rotating rod 13 will drive the rotating plate 12 to rotate, so that the next placing column 2 moves close to the wire drawing machine body 1, and then the iron wire on the placing column 2 is replenished and loaded quickly and effectively. Subsequently, the empty unwinding drum can be directly unloaded and replaced, and the normal operation of the wire drawing machine is not affected in this process. When the placing column 2 moves close to the wire drawing machine body 1 along with the rotating plate 12, the first gear 23 on the rotating block 22 fixed at the lower end of the placing column 2 will engage with the second gear 25, so that the second motor 26 can drive the placing column 2 to rotate for the unwinding operation.
