Description

Technical Field

[0001] The invention relates to the technical field of metal wire detection, and in particular to a sampling wire device suitable for fine metal wire materials. Background Art

[0002] The production of metal wire is a process in which the wire is continuously drawn at high speed and finally wound on the I-shaped wheel end to a certain length. During this period, due to the quality and inspection requirements of the metal wire, the metal wire needs to be sampled and its performance tested.

[0003] At present, metal wire sampling is done manually by wire winding. The I-wheel in the factory is generally fixed on the production line reel or placed on the ground. When sampling, manpower is required to reversely wind the metal wire from the I-wheel to a certain length. When the metal wire is bent or wound, its grain structure will not change significantly. However, in the process of manual wire winding, the I-wheel is fixed and does not rotate with the wire winding. Excessive pulling may cause the metal wire to straighten instantly. When it is straightened instantly, the metal wire will stretch, and it will undergo plastic deformation, causing the grains inside the metal wire to slip, and its physical properties will change, seriously affecting the accuracy of the detection. Summary of the invention

[0004] The object of the present invention is to provide a sampling wire device suitable for fine metal wire materials, which can avoid the situation in which the metal wire is instantly straightened and stretched during the metal wire sampling process, thereby improving the accuracy of detection.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a sampling wire device suitable for fine metal wire materials, including a machine platform, a rotating shaft for facilitating the rotation of the I-shaped wheel is rotatably provided on the machine platform, a deceleration assembly is provided on one side of the rotating shaft, the deceleration assembly includes a friction plate at one end of which can contact the rotating shaft for braking, and a winding assembly is provided on one side of the rotating shaft.

[0006] A further improvement of the present invention is that the deceleration assembly includes symmetrically arranged support plates, a horizontal axis is rotatably provided between the two support plates, a vertical plate is provided on the horizontal axis, the upper end of the vertical plate is connected to the friction plate, and the lower end of the vertical plate is connected to a pressure plate, and when the pressure plate is pressed down, the friction plate rises and contacts the rotating shaft to brake.

[0007] A further improvement of the present invention is that the winding assembly includes a vertical plate, a winding shaft is provided on the plate surface of the vertical plate, a circular plate is coaxially provided on the winding shaft, a sampling wheel is coaxially provided on the plate surface of the circular plate, and a transverse rod is provided on the plate surface of the circular plate and inside the inner opening of the sampling wheel to facilitate the rotation of the circular plate.

[0008] A further improvement of the present invention is that the winding assembly includes a vertical plate, a rotating shaft on the plate surface of the vertical plate is provided with a winding shaft, a fixed sleeve on the winding shaft is provided with an inner sleeve matching the inner diameter of the sample disk, and one end of the winding shaft is detachably connected to a crank.

[0009] A further improvement of the present invention is that the end of the friction plate that is in contact with the rotating shaft can remain drooping under normal conditions, and the end is provided with an arc opening that matches the rotating shaft.

[0010] A further improvement of the present invention is that at least one guide wheel is provided between the rotating shaft and the winding assembly.

[0011] A further improvement of the present invention is that a swivel seat is provided on the machine platform, the swivel shaft is rotatably connected to the swivel seat, and a tensioning ring engaged with the I-shaped wheel is provided on the swivel shaft.

[0012] A further improvement of the present invention is that a meter for recording the winding length is provided on the winding assembly.

[0013] A further improvement of the present invention is that a moving wheel is provided at the lower end of the machine.

[0014] The beneficial effects of the present invention are: The present invention provides a rotating shaft and a winding assembly and fixes the spool on the rotating shaft. When the winding assembly takes the wire, the spool can rotate with the traction, thereby avoiding the situation where the metal wire is instantly straightened, and enhancing the reliability and accuracy of the experimental results.

[0015] The present invention arranges a friction plate. When the pressure plate is pressed down, the friction plate rises and contacts the rotating shaft to brake. By slowly pressing down the pressure plate, the rotation speed of the rotating shaft can be smoothly reduced. When the winding is stopped, the rotation of the rotating shaft can be slowed down to avoid the situation where the wage wheel on the rotating shaft is continuously unwound due to inertia, resulting in excessive unwinding.

[0016] In actual production, wire is usually taken for detection. Sometimes the wire needs to be wound on a sample tray, with one part used for detection and the other part used for sample storage. The winding assembly of the present invention has two structures, one of which is provided with a sampling wheel. By winding the wire on the sampling wheel, it can be directly used for detection after winding. The other is provided with an inner sleeve matched with the inner diameter of the sample tray, which is convenient for installing the sample tray, facilitating actual use, and improving the scope of application of the device.

When the pressure plate 9 is pressed down, the friction plate 4 is tilted up and contacts the rotating shaft 2 to stop. The friction plate 4 is located above the horizontal axis 7, and the pressure plate 9 is located below the horizontal axis 7. The vertical plate 8 is tilted in a normal state, and the end of the friction plate 4 that can contact the rotating shaft 2 is kept drooping in a normal state (the pressure plate 9 is tilted up in a normal state), and the end is provided with an arc opening 17 that matches the rotating shaft 2.

Put the sampling disc on the inner sleeve 15 and fix it. Pull out the wire on the I-shaped wheel, pass it around the guide wheel 18 and fix the end of the wire on the sample disc. After the meter 21 is cleared, manually rotate the crank 16 at a constant speed and observe the value of the meter 21. When the required length is about to be reached, gently support the crank 16 to stop the winding shaft 11, and slowly press down the pressure plate 9 on the other side to make the friction plate 4 rise and gradually contact the rotating shaft 2, and decelerate the wheel shaft 2 to stop. Cut the wire, tie it up, and remove the sample disc.

[0031] Sampling of wire without reel: First, insert the I-shaped wheel into the rotating shaft 2, and move the position to the I-shaped wheel tensioning ring 20 to fix it. Pull out the wire on the I-shaped wheel, and pass it around the guide wheel 18 to fix the end of the wire on the sampling wheel 13. After the meter 21 is cleared, manually rotate the transverse rod 14 at a constant speed and observe the value of the meter 21. When the required length is about to be reached, gently lift the crank handle 16 to stop the winding shaft 11, and slowly press down the pressure plate 9 on the other side to make the friction plate 4 rise and gradually contact the rotating shaft 2, and decelerate the wheel shaft 2 to stop. Cut the wire and tie it up, and remove the sample wire.
