[0034] like Figure 6-10 As shown, this example can achieve the effect of preventing the steel wire from slipping when pulling the steel wire to test its strength.
[0035] Since the wire hanging seat 401 is provided with a wire hanging groove 404, the wire hanging groove 404 is divided into an upper side, a front side and a rear side, an arc groove 403 is provided in the middle of the upper side of the wire hanging groove 404, and the pressing block 201 is provided on the upper side of the wire hanging groove 404, and a convex arc block 205 is provided in the middle of the lower side of the pressing block 201, the steel wire can be placed on the steel hanging groove 404 on the wire hanging seat 401, and then the pressing block 201 is driven to move downward and press on the steel wire, thereby fixing the steel wire on the wire hanging seat 401, and the convex arc block 205 can press the steel wire into the arc groove 403, thereby preventing the steel wire from slipping when the steel wire is pulled to test its strength.
[0036] like Figure 6-10 As shown, this example can achieve the effect of the pressing block 201 sliding vertically along the two guide rods 203 .
[0037] Since guide rods 203 are welded to the left and right ends of the upper side of the wire hanger 401, the pressure block 201 is vertically slidably connected to the two guide rods 203, and the upper parts of the two guide rods 203 are connected to the top seat 202 by screws. The pressure block 201 is driven to slide by the hydraulic cylinder, and the pressure block 201 can slide vertically along the two guide rods 203 under the drive of the hydraulic cylinder.
[0038] like Figure 6-7 As shown, this example can achieve the effect of increasing friction through multiple ridges 204.
[0039] Since the lower side of the pressing block 201 is evenly distributed with a plurality of ridges 204 , the plurality of ridges 204 can contact the steel wire when the pressing block 201 is pressed on the steel wire, thereby increasing the friction force through the plurality of ridges 204 and further preventing the steel wire from slipping.
[0040] like Figure 6-10 As shown, this example can achieve the effect of stable vertical sliding between the two slot rods 101 through the two sliding parts 402 .
[0041] Since the stainless steel special steel wire tensile strength detection device also includes a bottom plate 107, slot rods 101 are welded to the left and right ends of the upper side of the bottom plate 107, and sliding parts 402 are integrally formed on both sides of the wire hanger 401. The two sliding parts 402 are respectively slidably connected to the two slot rods 101, so that the wire hanger 401 can stably slide vertically between the two slot rods 101 through the two sliding parts 402, thereby pulling the steel wire upward.
[0042] like Figure 4-5 As shown, this example can achieve the effect of slowly pulling the steel wire.
[0043] Since top sheets 103 are welded on the upper parts of the two slot rods 101, the upper parts of the two screw rods 102 are respectively rotatably connected to the two top sheets 103, the screw rod 102 cooperates with the corresponding sliding part 402 through threads, the upper part of the screw rod 102 is connected to a worm wheel 105, and the two top sheets 103 are fixed with convex pieces 104. The two ends of the worm 106 are respectively rotatably connected to the two convex pieces 104, and the worm 106 is meshed with the two worm wheels 105 for transmission. The worm 106 is driven to rotate by a servo motor, and the two worm wheels 105 are driven to rotate when the worm 106 is driven to rotate. The rotation of the two worm wheels 105 drives the two screw rods 102 to rotate respectively, and then the two wire hangers 401 and the sliding part 402 are stably driven to move upward at a micro-distance through the threads, so as to slowly pull the steel wire, test the distance passed by the critical point of the transition from overall uniform deformation to local concentrated deformation of the steel wire, and test the tensile strength of the stainless steel special steel wire.
[0044] like Figure 4-8 As shown, this example can achieve the effect of clamping and fixing the two ends of the steel wire.
[0045] Since the lower parts of the two slot rods 101 are connected with two front and rear connecting plates 302 by screws, the middle part of the main rod 301 is connected to the two connecting plates 302, and the front and rear ends of the main rod 301 are welded with a clamping piece 1 303, and each connecting piece 302 is slidably connected with a portal frame 305, and a clamping piece 2 306 is welded on the portal frame 305. The portal frame 305 is driven to slide by a hydraulic cylinder, and the clamping piece 1 303 and the clamping piece 2 306 are arranged opposite to each other. The two ends of the steel wire can be placed between the two groups of clamping pieces 1 303 and clamping pieces 2 306 respectively, and then the two ends of the steel wire are clamped and fixed, and then the steel wire is pressed upward by the wire hanger 401 to test the tensile strength of the steel wire.
[0046] like Figure 8 As shown, this example can prevent the clamping piece 1 303 and the clamping piece 2 306 from slipping when clamping the steel wire.
[0047] Since a plurality of anti-skid edges 304 are fixed from top to bottom on the first clamping piece 303 and the second clamping piece 306, the first clamping piece 303 and the second clamping piece 306 are prevented from slipping when clamping the steel wire.
[0048] like Figure 4-5 As shown, this example can achieve the effect of driving the screw rod 2 109 to rotate by a servo motor.
[0049] Since the track 108 is welded on the bottom plate 107, the right end of the track 108 is connected to the motor seat 110 by screws, the motor seat 110 is connected to the servo motor, and the output shaft of the servo motor is connected to the screw rod 109, so that the screw rod 109 can be driven to rotate by the servo motor.
[0050] like Figure 1-12 As shown, this example can achieve the effect of local short-distance tensile strength testing of steel wire.
[0051] Since the bracket 501 is slidably connected to the track 108, the screw rod 109 cooperates with the bracket 501 through a thread, a flat column 502 is welded on the upper part of the bracket 501, and the front and rear ends of the flat column 502 are slidably connected with lower clamping blocks 507, and the lower clamping blocks 507 are driven to slide by a hydraulic cylinder. A column 505 is welded on the upper side of each lower clamping block 507, and each column 505 is vertically slidably connected with an upper clamping block 503. The lifting rod 504 is slidably connected to the two upper clamping blocks 503 in the front and rear directions. The lifting rod 504 is driven to rise and fall by the hydraulic cylinder, and the screw rod 109 is driven to rotate to drive the bracket 501 to move along the track 10 8 Slide to the left and move the two lower clamps 507 and the two upper clamps 503 to the steel wire, so that the steel wire is placed between the two lower clamps 507 and also between the two upper clamps 503, and then drive the two lower clamps 507 to move closer to each other to clamp the steel wire. At this time, the two columns 505 and the two upper clamps 503 will also move closer to each other to clamp the steel wire, and then drive the lifting rod 504 to move upward, so that the two upper clamps 503 slide upward on the two columns 505 respectively, and then the steel wire is pulled away from each other by the two upper clamps 503 relative to the two lower clamps 507, so as to perform a local short-distance tensile strength test on the steel wire.
[0052] like Figure 11-12 As shown, this example can achieve the effect that the upper clamping block 503 and the lower clamping block 507 are not easy to slip when clamping the steel wire.
[0053] Since the second anti-skid edge 506 is welded on both the upper clamping block 503 and the lower clamping block 507 , the second anti-skid edge 506 makes it difficult for the upper clamping block 503 and the lower clamping block 507 to slip when clamping the steel wire.
