Description

Technical Field

[0001] The invention relates to the technical field of copper wire testing equipment, and in particular to a phosphor bronze wire strength testing device. Background Art

[0002] The existing high-strength and high-elasticity phosphor bronze wire has good wear resistance, corrosion resistance, easy electroplating and high elasticity and is widely used. Therefore, the strength test of phosphor bronze wire is often indispensable. In this regard, in the prior art, such as the carbon brush copper wire tensile test tool disclosed in CN205879428U, a copper wire strength test tensile machine disclosed in CN214066742U, etc., both clamp the two ends of the copper wire through a clamping mechanism, and then drive the clamping mechanism to move horizontally, so as to directly stretch the copper wire along the length direction of the copper wire. However, there is a need to manually clamp the copper wire end on the clamping tool and fix it firmly, which is time-consuming and laborious. When testing the tensile strength, it is easy to break at the clamping end, thereby affecting the accuracy of the test. In addition, considering that in actual applications, the copper wire does not completely maintain a straight state, especially the phosphor bronze wire, due to its high elasticity, it is likely to be in a bending state of different degrees, and the existing detection device is difficult to simultaneously detect the strength of the copper wire in a straight state and a bending state of different degrees, so it needs further research and development and optimization. Summary of the invention

[0003] In view of this, the purpose of the present invention is to propose a phosphor bronze wire strength detection device to solve the problems of existing phosphor bronze wire detection devices, such as time-consuming and labor-intensive operation, easy breakage of the clamping ends, and difficulty in simultaneously detecting the strength of the copper wire in a straight state and in different degrees of bending.

[0004] Based on the above purpose, the present invention provides a phosphor bronze wire strength detection device, including a detection platform:

[0005] The two sides of the testing table are rotatably connected with winding drums for rotating and tensioning the copper wire;

[0006] A through slot is provided on the testing table, and the through slot is designed in a T-shaped shape. The bottom end of the testing table is connected to a slide frame along the longitudinal sliding direction, a slider is connected to the inner side of the slide frame along the transverse sliding direction, a roller is connected to the inner side of the slider along the vertical sliding direction, and the top end of the roller passes upward along the through slot and is connected to a variable diameter roller. The outer diameter of the variable diameter roller changes gradually from top to bottom, and a testing cover is connected to the outer side of the variable diameter roller, and a gap is left between the testing cover and the outer side of the variable diameter roller;

[0007] A driving mechanism is provided at the bottom end of the detection table. When the driving mechanism pushes the slide to slide longitudinally, the roller shaft moves along the longitudinal edge of the through groove, which is used to push the tensioned copper wire to stretch longitudinally, and the detection cover detects the copper wire attached to the outside of the variable diameter roller. When the driving mechanism pushes the slide to slide transversely, the roller shaft moves along the transverse edge of the through groove, which is used to push the detection cover to move transversely along the tensioned copper wire for detection.

[0008] Preferably, the axial direction of the winding drum and the axial direction of the diameter-changing roller are both arranged perpendicular to the table surface of the detection table.

[0009] Preferably, the diameter-changing roller is provided with wire grooves along its circumference, and a plurality of wire grooves are arranged from top to bottom.

[0010] Preferably, a plurality of limiting holes are provided on the roller shaft from top to bottom, the spacing between adjacent limiting holes is the same as the spacing between adjacent wire grooves, and a limiting rod is inserted into the outer end of the slider for inserting into the limiting hole for limiting.

[0011] Preferably, a strip-shaped sliding groove is transversely opened in the middle of the sliding frame, and the sliding block is transversely slidably connected in the sliding groove.

[0012] Preferably, the top end of the variable diameter roller is connected to a transverse cover, and the top end of the detection cover is connected to the outer side end of the transverse cover.

[0013] Preferably, the detection cover is designed to be in an arc shape concentric with the diameter-changing roller.

[0014] Preferably, a flaw detector is provided on the side of the detection cover facing the variable diameter roller.

[0015] Preferably, a protective cover is provided on the detection platform.

[0016] The beneficial effects of the present invention are as follows: winding drums are connected to the two sides of the testing platform for rotating and tensioning the copper wire. The sliding height of the roller shaft along the slider is adjusted according to the needs, so as to adjust the height position of the variable diameter roller. The slide frame is pushed to slide longitudinally by the driving mechanism so that the roller shaft moves along the longitudinal edge of the through groove. At this time, the variable diameter roller pushes the tensioned copper wire to stretch longitudinally, so as to realize the strength detection of the copper wire under different degrees of bending state. Moreover, since the copper wire is more likely to produce orange peel or cracking phenomenon at the stretching bending part, the copper wire attached to the outer side of the variable diameter roller is detected by the detection cover, which is conducive to more efficient real-time detection on the one hand, and provides protection on the other hand. When it is necessary to detect the linear tensile strength of the copper wire, the winding drum is controlled to be continuously tightened, and the slider is pushed to slide transversely by the driving mechanism so that the roller shaft moves along the transverse edge of the through groove. The detection cover moves transversely along the tensioned copper wire for detection, as shown in the figure, which is conducive to real-time and efficient detection of surface damage of the linearly stretched copper wire.

[0029] like Figures 1 to 7 As shown, a phosphor bronze wire strength testing device comprises a testing platform 1, and winding drums 2 are rotatably connected on both sides of the testing platform 1 for rotating and tensioning the copper wire 100. A through slot 3 is provided on the testing platform 1, and the through slot 3 is designed in a T-shaped shape. A slide 4 is slidably connected to the bottom end of the testing platform 1 along the longitudinal direction, a slider 5 is slidably connected to the inside of the slider 4 along the transverse direction, and a roller 6 is slidably connected to the inside of the slider 5 along the vertical direction. The top end of the roller 6 passes upward along the through slot 3 and is connected to a variable diameter roller 7. The outer diameter of the variable diameter roller 7 gradually changes from top to bottom, and the outer end of the variable diameter roller 7 is A detection cover 8 is connected, and a gap is left between the detection cover 8 and the outer end of the variable diameter roller 7. A driving mechanism 9 is provided at the bottom end of the detection platform 1. When the driving mechanism 9 pushes the slide 4 to slide longitudinally, the roller shaft 6 moves along the longitudinal edge of the through groove 3, which is used to push the tensioned copper wire 100 to stretch longitudinally, and the detection cover 8 detects the copper wire 100 attached to the outer side of the variable diameter roller 7. When the driving mechanism 9 pushes the slider 5 to slide horizontally, the roller shaft 6 moves along the horizontal edge of the through groove 3, which is used to push the detection cover 8 to move horizontally along the tensioned copper wire 100 for detection.

[0030] The present invention is based on the existing strength testing equipment, including a testing platform 1, on both sides of the testing platform 1 are respectively connected to the winding drum 2 for rotation. Specifically, the winding drum 2 is arranged vertically, that is, the axial direction of the winding drum 2 is perpendicular to the table surface of the testing platform 1. The winding drum 2 may be provided with a plug hole. When in use, the two ends of the copper wire 100 are respectively inserted into the plug holes of the winding drum 2 on both sides, and the winding drums 2 on both sides are turned on to rotate in opposite directions, for example Figure 1As shown, the winding drum 2 on the left rotates clockwise, and the winding drum 2 on the right rotates counterclockwise, and the winding drum 2 rotates and reels until the copper wire 100 is horizontally tensioned. At this time, the end of the copper wire 100 has been buried in the copper wire 100 wound by the winding drum 2, so it will not get loose. After the detection is completed, it is only necessary to control the winding drum 2 to rotate and release the wire, so as to achieve the clamping and fixing of the end of the copper wire 100, without too much manual auxiliary operation, saving time and effort, and the two ends of the copper wire 100 are evenly wound and stressed. Compared with the hard clamping at the two ends, it is not easy to be stretched and broken at the end to affect the detection accuracy. At the same time, a through groove 3 is opened on the detection table 1, and the through groove 3 is designed in a T-shape. The bottom end of the detection table 1 is connected with a slide 4 along the longitudinal sliding. , a slider 5 is connected to the slide 4 in a horizontal sliding manner, a roller 6 is connected to the slider 5 in a vertical sliding manner, the top end of the roller 6 passes upward along the through slot 3, and is connected to a variable diameter roller 7, the variable diameter roller 7 is also arranged vertically, that is, the axial direction of the variable diameter roller 7 is perpendicular to the table surface of the detection table 1, and the outer diameter of the variable diameter roller 7 gradually changes from top to bottom, and at the same time, a detection cover 8 is connected to the outer end of the variable diameter roller 7, and a gap is left between the detection cover 8 and the outer end of the variable diameter roller 7. Specifically, a flaw detector is provided on the side of the detection cover 8 facing the variable diameter roller 7. The flaw detector adopts existing conventional equipment and tools such as ultrasonic flaw detectors, infrared thermal imaging flaw detectors, and visual imaging detectors for non-contact real-time flaw detection;

[0031] A driving mechanism 9 is provided at the bottom end of the testing platform 1. When in use, the sliding height of the roller shaft 6 along the slider 5 is adjusted as needed, so that the corresponding outer diameter position on the variable diameter roller 7 corresponds to the height position of the winding drum 2 for transversely tensioning the copper wire 100. The driving mechanism 9 pushes the carriage 4 to slide longitudinally so that the roller shaft 6 moves along the longitudinal side of the through slot 3. At this time, Figure 2 As shown, the variable diameter roller 7 pushes the tensioned copper wire 100 to stretch in the longitudinal direction, and the copper wire 100 is stretched by bending the copper wire 100 at different outer diameters on the variable diameter roller 7, so as to realize the strength detection of the copper wire 100 under bending conditions of different degrees. In addition, since the copper wire 100 is more likely to produce orange peel or cracking phenomenon at the stretching bending part, the copper wire 100 attached to the outer side of the variable diameter roller 7 is detected by the detection cover 8, which is conducive to more efficient real-time detection on the one hand, and convenient for the research and development staff to know experimentally at what strength or elongation the orange peel phenomenon occurs when stretched, and at what stretch At what strength or elongation does cracking occur, at what strength or elongation does rupture occur, and when the wire is broken, the detection cover 8 provides protection, which is conducive to efficient protection and positioning and collecting broken wire fragments. If it is necessary to detect the linear tensile strength of the copper wire 100, the slider 5 is pushed to slide horizontally through the driving mechanism 9 to move the roller 6 along the lateral edge of the through groove 3. The linear tensile strength of the copper wire 100 can be detected by continuously tightening the winding drum 2, and the detection cover 8 moves horizontally along the tensioned copper wire 100 for detection. Figure 3 As shown, it is beneficial to detect the surface damage of the straight-line stretched copper wire 100 in real time and efficiently.

[0032] In an embodiment of the present invention, Figure 4 As shown, a wire groove 71 is provided on the diameter-changing roller 7 along its circumference, and a plurality of wire grooves 71 are arranged from top to bottom, so as to facilitate the copper wire 100 to be bent and stretched along the wire grooves 71 of different diameters.

[0033] In an embodiment of the present invention, Figure 4 As shown, a plurality of limit holes 10 are provided on the roller shaft 6 from top to bottom, and the spacing between adjacent limit holes 10 is the same as the spacing between adjacent wire grooves 71. A limit rod 11 is inserted into the outer end of the slider 5 for inserting into the limit hole 10 for limiting, so as to facilitate efficient adjustment of the height of the variable diameter roller 7. Preferably, the inner end of the limit rod 11 can be designed as a threaded section and be threadedly connected to the limit hole 10.

[0034] In an embodiment of the present invention, Figure 4 , Figure 5 , Figure 6 As shown, a strip-shaped slide groove 41 is transversely opened in the middle of the slide 4, and the slider 5 is transversely slidably connected in the slide groove 41. Preferably, the lower end of the slider 5 is penetrated and located below the slide groove 41 to facilitate the operation of the limit rod 11.

[0035] Specifically, the driving mechanism 9 may include conventional existing equipment such as a telescopic cylinder, a driving motor, etc. For example, the output end of the telescopic cylinder is connected to the slide 4 to push the slide 4 to slide longitudinally along the bottom end of the detection platform 1, or the drive motor drives the lead screw to rotate and drives the nut on the lead screw to move, thereby driving the slide 4 to slide longitudinally along the bottom end of the detection platform 1. Similarly, similar telescopic cylinders, driving motors and other equipment are also provided on the adjacent side of the bottom end of the detection platform 1, and the output end thereof is connected to a U-shaped push block 90. ​​When the roller shaft 6 moves along the longitudinal edge of the through groove 3, as shown in FIG. Figure 2 As shown, the slider 5 moves longitudinally and disengages from the push block 90 until the slider 5 moves to the middle of the bottom edge of the through groove 3, as shown in FIG. Figure 1 , Figure 7 As shown, the slider 5 moves into the push block 90 and engages therein, and the push block 90 is driven to move back and forth laterally by the telescopic cylinder, the drive motor and other devices. Figure 3 As shown, the roller shaft 6 reciprocates along the lateral edge of the through slot 3.

[0036] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, the top end of the variable diameter roller 7 is connected to a transverse cover 80 , and the top end of the detection cover 8 is connected to the outer end of the transverse cover 80 , so that a gap is left between the detection cover 8 and the outer end of the variable diameter roller 7 .

[0037] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, the detection cover 8 is designed to be in an arc shape concentric with the diameter-changing roller 7 .

[0038] In an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, a protective cover 12 is provided on the upper cover of the testing platform 1, and the protective cover 12 is detachably connected, so as to facilitate the convenient release and reeling of the line and provide further protection.
