Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 9As shown, a stretching equipment for industrial wire production comprises: a fixed base 1, a test frame 2 is fixedly installed on the top of the fixed base 1, a first mounting frame 3 is fixedly installed on the right side of the top, a swing seat 4 is rotatably connected to the right end of the front side of the first mounting frame 3, a reeling shaft 5 is rotatably connected to the front side of the reeling shaft 5, a test reel 6 is fixedly installed on the outside of the reeling shaft 5, a reeling mechanism 7 is fixedly installed on the front side of the first mounting frame 3 and on the left side of the test reel 6, a first fixed seat 8 is fixedly installed on the top of the front side of the fixed base 1, a lifting seat 9 is slidably connected to the bottom end of the inside of the test frame 2, a second fixed seat 10 is fixedly installed at the front end of the lifting seat 9 and on the front side of the test frame 2, a wire drawing mechanism 11 is fixedly installed on the right side of the test frame 2 and on the right side of the second fixed seat 10, and a collecting box 12 is movably installed on the right side of the test frame 2 and below the wire drawing mechanism 11.

[0019] The first fixed seat 8 and the second fixed seat 10 are both provided with an arc-shaped winding groove 801 on the left side, and the first fixed seat 8 and the second fixed seat 10 are both provided with a through groove 802 at the end away from each other. The first fixed seat 8 and the second fixed seat 10 are both provided with an active cavity 803 inside. The first cylinder 804 is fixedly installed on the opposite side of the two groups of active cavities 803. The driving ends of the two groups of first cylinders 804 are both fixedly installed with a fixed plate 805. The inner sides of the two groups of fixed plates 805 are provided with a clamping groove 806. When the industrial wire is subjected to a tensile test, the industrial wire is first inserted from the top of the first fixed seat 8, and then passes around the arc-shaped winding groove 801 on the outside of the first fixed seat 8 and the second fixed seat 10 in turn, and then the industrial wire is inserted from the bottom end of the second fixed seat 10 into the through groove 802, and then the industrial wire is introduced into the wire drawing mechanism 11, and the first fixed seat 8 is started first. The first cylinder 804 pushes the fixing plate 805, and the industrial wire is clamped and fixed through the clamping groove 806 on the inner side of the fixing plate 805. Then, the bottom end of the industrial wire is tightened by the wire drawing mechanism 11, and then the first cylinder 804 inside the second fixing seat 10 is started to push the fixing plate 805 to clamp and fix the bottom end of the industrial wire, so that a section of the industrial wire is fixed between the first fixing seat 8 and the second fixing seat 10. At this time, the lifting seat 9 is lowered to perform a tensile test on the industrial wire. Not only is the operation simple and can ensure the fixing effect of the industrial wire, but also the arc-shaped winding groove 801 can reduce friction when the industrial wire is pulled, so that the wire bundle is smoother during the stretching process, thereby improving the precision and accuracy of the test. At the same time, it can reduce friction and avoid stress concentration, thereby reducing the risk of breakage during the test, thereby protecting the device and improving the reliability of the test.

[0020] In this embodiment, a limiting plate 807 is fixedly installed on the front of the test frame 2 and below the first fixed seat 8. The clamping groove 806 of the second fixed seat 10 is internally fixedly connected with multiple groups of anti-slip protrusions 808.

A second cylinder 304 is rotatably connected to the back of the first mounting frame 3 and located below the first motor 301, and a driving end of the second cylinder 304 is rotatably connected to the swing seat 4. When the industrial wire is subjected to a tensile test, after the test reel 6 is mounted on the outside of the unwinding shaft 5, the first motor 301 is started to drive the unwinding shaft 5 to rotate through the pulley group 302, thereby automatically unwinding the test reel 6. The stability of the pulley group 302 is ensured by the stabilizing wheel 303, and at the same time, the second cylinder 304 can push the swing seat 4 to ensure the tension state of the pulley group 302. During the tensile test of the industrial wire, the industrial wire can be stably released to perform multiple-segment tests on the industrial wire on the same test reel 6, thereby further improving the precision and accuracy of the test.

Since the bottom end of the slider 704 is slidably connected with the guide shaft 702 through the guide groove 703, the slider 704 is driven to reciprocate on the top of the frame 701, thereby guiding the industrial wire evenly and stably, the industrial wire is first inserted from the top of the first fixed seat 8, and then bypasses the arc-shaped groove 801 on the outside of the first fixed seat 8 and the second fixed seat 10 in turn, and then the industrial wire is inserted from the bottom end of the second fixed seat 10 into the inside of the groove 802, and then the industrial wire is introduced into the inside of the wire drawing mechanism 11, and the first cylinder 804 inside the first fixed seat 8 is started first. The fixing plate 805 is pushed, and the industrial wire is clamped and fixed through the clamping groove 806 on the inner side of the fixing plate 805. Then, the bottom end of the industrial wire is tightened by the wire drawing mechanism 11, and then the first cylinder 804 inside the second fixing seat 10 is started to push the fixing plate 805 to clamp and fix the bottom end of the industrial wire, so that a section of the industrial wire is fixed between the first fixing seat 8 and the second fixing seat 10. At this time, the lifting seat 9 is lowered to perform a tensile test on the industrial wire. During this process, the downward movement distance of the lifting seat 9 is controlled by observing the position of the pointing groove 904 pointing to the scale line 903, so as to accurately test the tensile strength of the industrial wire. Not only is the operation simple and can ensure the fixing effect of the industrial wire, but also the arc-shaped winding groove 801 can reduce friction when the industrial wire is pulled, so that the wire bundle is smoother during the stretching process, which improves the precision and accuracy of the test. At the same time, it can reduce friction and avoid stress concentration, thereby reducing the risk of breakage during the test. The design of the present invention is not only simple to operate but also can ensure the fixing effect of the industrial yarn, and the yarn bundle is smoother during the stretching process, thereby improving the precision and accuracy of the test. At the same time, it can reduce friction and avoid stress concentration, thereby reducing the risk of breakage during the test, thereby protecting the device and improving the reliability of the test. In addition, the industrial yarn can be stably released for multi-segment testing, further improving the precision and accuracy of the test.
