Description

Technical Field

[0001] The invention relates to the field of winding equipment, and in particular to a wire reel diameter measuring device, a wire reel diameter measuring method and a wire reel processing equipment. Background Art

[0002] In the prior art, the preparation of metal wires is usually completed by drawing process. Metal wire drawing is a metal plastic processing process in which a wire rod or wire blank is pulled out from the die hole of a wire drawing die under the action of a drawing force to produce a small-section steel wire or non-ferrous metal wire. For example, the preparation of steel cord mainly involves drawing the steel wire into a wire of a set diameter through a water tank wire drawing machine, and then winding the wire on a take-up wheel.

[0003] The products produced by some wire drawing equipment have unstable ring diameter during use, which affects the stability of the outer diameter and initial tension of the product. This is because the diameter of the drawing mouth increases due to long-term working friction, which affects the compression ratio between wire drawing passes. In this case, the magnitude and direction of the residual stress generated by the material during the wire drawing process are unevenly distributed on the cross section, causing the wire to be wavy. Therefore, it is necessary to limit the diameter of the wire ring to ensure the stability of the product ring diameter. For some products with high precision requirements, the single wire ring diameter needs to be controlled at 200±50mm. In the prior art, the measurement of the ring diameter is usually carried out manually with tools such as vernier calipers. For example, the Chinese invention patent with publication number CN104406494A discloses a detection device and method for the yield ring diameter of hose steel wire, in which a vernier caliper is used to measure the yield ring diameter. After drawing the metal wire product, the operator needs to carry a ruler with him for detection, which is extremely inefficient and the accuracy needs to be improved, and it is impossible to achieve fully automated production requirements. In mass production, in order to ensure the stability of the ring diameter of metal wire products, it is necessary to conduct random inspections on the ring diameter of the products and ensure that the ring diameters of the inspected products are within the standard range required by customers.

[0055] In some embodiments, a cover plate is provided on the top of the bracket, and the cover plate is provided directly above one section of the moving path of the test carrier 101. The wire feeding mechanism further includes a first rotating shaft 111 and a second rotating shaft 112, and the first rotating shaft 111 and the second rotating shaft 112 are provided at the bottom of the cover plate, and the axes of the first rotating shaft 111 and the second rotating shaft 112 are parallel to the axis of the wire unwinding machine 102, wherein a first guide rail 116 is provided on the top of the first rotating shaft 111 along its radial direction, and the first rotating shaft 111 is connected to the first guide rail 116 through a slider 115 and translates along the first guide rail 116, and the first rotating shaft 111 and the slider 115 can be moved by The bearing connection ensures that the first rotating shaft 111 does not interfere with the slider 115 when rotating.

The fuse mechanism 303 and the wire diameter measuring mechanism are arranged on the same mounting frame, and the mounting frame is driven by a cylinder or a motor to translate along the y-axis and / or z-axis direction. The translation of the mounting frame can be achieved by cooperating with guide mechanisms such as guide rails and moving modules. This is a prior art and will not be described in detail here. The synchronous adjustment of the working heights of the fuse mechanism 303 and the wire diameter measuring mechanism is achieved. When the waste wire clamp 311 clamps the wire b1 and resets, due to the wire b 1 is fixed at both ends by the waste wire clamp 311 and the wire twisting clamp 310. Therefore, it is only necessary to adjust the position of the mounting frame so that the wire b1 enters the working position of the fuse mechanism 303 and the wire diameter measuring mechanism, so as to simultaneously complete the fusing and wire diameter measurement of the wire b1. In a preferred embodiment, the working positions of the fuse mechanism 303 and the wire diameter measuring mechanism as well as the wire twisting clamp 310 and the waste wire clamp 311 are located at the same height. When the waste wire clamp 311 clamps the wire b1 and resets it, the wire b1 automatically enters the working position of the fuse mechanism 303 and the wire diameter measuring mechanism, and there is no need to adjust the position of the fuse mechanism 303 and the wire diameter measuring mechanism, thereby maximizing the work efficiency and simplifying the configuration.

Specifically, the positioning pressure block 313 is driven to lift by a cylinder. When the thread taking-up rod 305 needs to descend, the cylinder drives the positioning pressure block 313 to press on the top of the pull-down plate 316 and continue to descend. The pull-down plate 316 descends. At this time, the elastic member is driven to be pulled down by the pull-down plate 316, and the two guide rods 306 are also driven to descend along the guide holes, and then the thread taking-up rod 305 at the top of the two guide rods 306 also descends accordingly; when the thread taking-up rod 305 needs to be reset, the positioning pressure block 313 rises and leaves the pull-down plate 316, the pressure disappears, and the elastic member drives the guide rods 306 and the thread taking-up rod 305 to automatically reset.
