Abstract
Description
Technical Field
[0001] The invention relates to the technical field of metal wire drawing and traction devices, and in particular to a metal wire pay-off system. Background Art
[0002] When drawing and traction of metal wire, the metal wire on the pay-off system needs to be quickly paid out, and the metal wire is thinned through multiple cycles of coating, heating, and die extrusion. Then, the metal wire is quickly and neatly wound onto the take-up system through the wire arrangement component.
[0003] In the prior art, the wire head is often pulled manually. When the wire head reaches the mold entrance, the wire stops moving quickly. During this process, if the resistance of the pay-off reel is too large, the wire will be directly broken. When the resistance of the pay-off reel is too small, after the wire head stops moving, the pay-off reel continues to rotate due to inertia, and the wire will continue to be fed out. At this time, the wire is too long and not constrained, and the wire is prone to jumping and disconnecting. When the operator pulls the wire head again, the wire will be cut by the components in the equipment, seriously affecting the continuity of production. In addition, during normal production, when the wire is quickly released from the pay-off reel, the number of wires will become less and less, and the rotation inertia of the pay-off reel is always changing, and the wire shaking is easy to increase. Although the vibration absorption spring in the original equipment can reduce some of the shaking, when the inertia changes too much, the wire will jump more significantly and then detach from the equipment, which will cause the wire to break, which is easy to cause equipment shutdown and affect production efficiency.

[0026] A base 5 is fixed to the bottom plate 1 of the equipment by screws, and a fixed guide wheel mechanism for guiding the movement of the metal wire is provided on the base 5; a moving guide wheel mechanism for guiding the movement of the metal wire is provided on the fixed guide wheel mechanism, and a channel for the movement of the metal wire is provided between the fixed guide wheel mechanism and the moving guide wheel mechanism.
[0027] In some technical solutions of the present invention, the moving guide wheel mechanism includes a mounting rod 18 arranged on the base 5, the mounting rod 18 is provided with a first sliding seat 7, the first sliding seat 7 is rotatably provided with a second guide wheel 9, the mounting rod 18 is provided with a second spring 16 abutting against the first sliding seat 7, and the base 5 is provided with a second guide rod 13 to guide the movement of the first sliding seat 7.
[0028] Furthermore, the first sliding seat 7 is slidably connected to the mounting rod 18 and the second guide rod 13 via linear sliding bearings.
[0029] In some technical solutions of the present invention, the fixed guide wheel mechanism includes a fixed guide wheel seat 6, which has two mounting holes respectively adapted to the mounting rod 18 and the second guide rod 13, the mounting rod 18 and the second guide rod 13 are both inserted into the mounting holes, and the fixed guide wheel seat 6 is rotatably provided with a first guide wheel 8.
[0030] In some technical solutions of the present invention, a second sliding seat 12 is sleeved on the mounting rod 18, a first spring 15 connected to the second sliding seat 12 is sleeved on the mounting rod 18, a third guide wheel 11 is rotatably provided on the second sliding seat 12, and a first guide rod 10 connected to the base 5 is passed through the second sliding seat 12.
[0031] Furthermore, the second sliding seat 12 is slidably connected to the mounting rod 18 and the first guide rod 10 via linear sliding bearings.
[0032] In some technical solutions of the present invention, a limiting block 17 abutting against the first spring 15 is provided on the free end of the mounting rod 18 .
[0033] In some technical solutions of the present invention, the shaft diameter of the first guide wheel 8 is smaller than the shaft diameter of the wheel groove of the second guide wheel 9.
[0034] In some technical solutions of the present invention, the control member is a magnetic powder brake 4, which is fixedly mounted on the bracket 19 by bolts, and the output end of the magnetic powder brake 4 is connected to the shaft of the pay-off drum 2 by a coupling or a sleeve transmission. The magnetic powder brake 4 can slow down the rotation speed of the pay-off drum 2, provide a continuous small tension for the pay-off drum 2, and keep a certain tension of the metal wire.
[0035] In some technical solutions of the present invention, a position detection sensor is provided in the middle of the first sliding seat 7, and the position detection sensor is connected to the electromagnet 3 by signal. Through the above-mentioned structure, the position detection sensor can control the electromagnet 3 to lock the pay-off drum 2 through the PLC controller to start and stop the pay-off drum, thereby achieving the purpose of emergency braking.
[0036] The working principle of this structure is as follows: when the metal wire is pulled continuously, the second guide wheel 9 slides upward along the axial direction of the mounting rod 18, and the third guide wheel 11 moves downward along the sliding axis. The second spring 16 provides force to control the second guide wheel 9, and the first spring 15 controls the movement of the third guide wheel 11. The second guide wheel 9 and the third guide wheel 11 work together to keep the metal wire in a stressed state, thereby absorbing the vibration of the metal wire; when the inertia is large and the vibration of the metal wire is too large, the second guide wheel 9 moves downward on the mounting rod 18, and the second guide wheel 9 is subjected to the downward pressure applied by the second spring 16, and the first sliding seat 6 moves downward to the specified position, and the position of the position detection sensor 14 also moves downward on the mounting rod 18 accordingly; the position detection sensor 14 sends a signal to the electromagnet 3 to put it in a working state, at which time the electromagnet 3 brakes the pay-off reel 2, and at the same time the first guide wheel 8 The part is embedded in the wheel groove of the second guide wheel 9 to form a closed space, which limits the metal wire and clamps it at the same time. At this time, the metal wire stops being fed out and the metal wire always stays in the closed space; when the metal wire head is pulled again, the position of the position detection sensor 14 in the vertical direction changes again. At this time, the position detection sensor 14 moves upward on the mounting rod 18, and it stops sending signals. At this time, the electromagnet 3 releases the traction action on the wire-paying drum 2, and the metal wire is still in the groove of the guide wheel 4. At the same time, it will also be in the groove of the guide wheel 8, and the closed space formed in the wheel groove of the first guide wheel 8 and the wheel groove of the second guide wheel 9 is used to limit the metal wire; during the above-mentioned action, the magnetic powder brake 4 controls the rotation speed of the wire-paying drum 2, provides a continuous small tension for the metal wire, and keeps a certain tension on the metal wire. Therefore, the above-mentioned structure can prevent the problem of abnormal wire breakage caused by shaking.
[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
