Description

Technical Field

[0001] The utility model relates to the technical field of tensile testing, and more specifically, to a tensile testing device for stainless steel wire production. Background Art

[0002] The tensile testing device for stainless steel wire production can apply a gradually increasing tensile force to the stainless steel wire until it breaks, so as to measure the tensile strength of the stainless steel wire. This parameter is an important index for evaluating the quality of stainless steel wire and helps to ensure that the product can withstand the expected tensile load.

[0003] In the existing publicly disclosed technical literature, the patent with the Chinese patent publication number CN215339263U discloses a tensile strength testing device for stainless steel wire production. After the steel wire passes through the rope cavity and the first rope hole, one end of it passes through the second rope hole at the left end or the right end again, and then the steel wire is wound around its own surface twice and passes through the second rope hole at the other end. Finally, the steel wire is wound around the surface of the fixed foot, so that the steel wire can be fixed. This device can improve the fixing stability of the steel wire without complex knotting steps; however, the testing device has the following problems.

[0004] During the production of stainless steel wire, the testing device needs to conduct tensile testing on the stainless steel wire. By applying a tensile force to the stainless steel wire, it is judged whether the stainless steel wire breaks. If it does not break, the stainless steel wire is not damaged. If it breaks, the stainless steel wire is in an unqualified state. The stainless steel wire is mainly in a vertical state for tensile adjustment, and it is difficult to detect the stainless steel wire at different angles. The detection applicability is poor. Therefore, a tensile testing device for stainless steel wire production is provided. Summary of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a tensile testing device for stainless steel wire production.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A tensile testing device for stainless steel wire production, including a box body. A sliding frame is welded on one side of the box body. A sleeve block is slidably connected to the inner wall of the sliding frame. A displacement detection component is installed at the top of the sleeve block; the displacement detection component includes an offset frame fixedly installed at the top of the sleeve block, and a positioning screw is welded to the bottom end of the inner wall of the offset frame. A nut is threadedly connected to the outer wall of the positioning screw; a linkage screw is threadedly connected to the inner wall of the sleeve block, and a driving motor is fixedly installed at one end of the sliding frame. The driving motor is used to drive the linkage screw to rotate.

[0007] One side of the offset frame is provided with a sliding plate fixedly connected to the box body. A socket block is welded on one side of the sliding plate. One side of the socket block is fixedly installed with a tensile electric cylinder. The contraction end of the tensile electric cylinder is fixedly installed with a tensile sensor, and the sensing end of the tensile sensor is fixedly connected with a concave strip.

[0008] Preferably, the output end of the driving motor is fixedly connected to the linkage screw rod, and the outer wall of the linkage screw rod is rotatably connected to the sliding frame. The lower surface of the offset frame is slidably connected to the box body, and the upper surface of the box body and the outer wall of the offset frame are both smooth surfaces. Two hinged doors are hinged on the inner wall of the box body, and there is a gap between the two hinged doors. The bottom end of the inner wall of the concave strip is welded with a pulling screw rod, and the outer wall of the pulling screw rod is threadedly connected with a pressing nut; both the pressing nut and the pulling screw rod are made of stainless steel.

[0009] When in use according to the above technical solution, by starting the tensile electric cylinder to drive the tensile sensor to move rightward, the tensile sensor drives the concave strip to move rightward, and the pulling screw rod drives the produced stainless steel wire to move rightward and pull. By starting the driving motor to drive the linkage screw rod to rotate forward, the sleeve block moves rightward along the inner wall of the sliding frame, the offset frame drives the positioning screw rod to move rightward, and the positioning screw rod drives the produced stainless steel wire to move rightward and pull. Then, by driving the linkage screw rod to rotate reversely by the driving motor, the offset frame drives the positioning screw rod to move leftward, and the positioning screw rod drives the produced stainless steel wire to move leftward. In this way, the produced stainless steel wire can perform tensile sensing on the tensile sensor.

[0010] Preferably, an auxiliary rolling assembly is installed at the top end of the inner wall of the box body; the auxiliary rolling assembly includes two connecting shafts rotatably installed at the top end of the inner wall of the box body. A side roller is welded to the bottom end of each connecting shaft, and the side roller is rotatably connected to the concave strip; the auxiliary rolling assembly further includes a socket shaft block, a rotating shaft, and a flat roller; the socket shaft block is fixedly connected to one side of the concave strip, and the rotating shaft is rotatably connected to the inner wall of the socket shaft block, and the flat roller is fixed to one end of the rotating shaft. The outer walls of the two side rollers are both smooth surfaces, and the cross section of the side roller is circular.

[0011] When in use according to the above technical solution, during the offset pulling process of the produced stainless steel wire inside the concave strip, the side roller drives the connecting shaft to rotate, the connecting shaft rotates on the concave strip, and at the same time the produced stainless steel wire rolls on the flat roller, and the rotating shaft rotates inside the socket shaft block, avoiding directly scraping and damaging the produced stainless steel wire.

[0012] The technical effects and advantages of the present utility model:

[0013] 1. The utility model adopts a displacement detection component. By starting the tension electric cylinder to drive the tension sensor to move rightward, the tension sensor drives the concave strip to move rightward, and the concave strip drives the pulling screw to move rightward. Starting the driving motor to drive the linkage screw to rotate forward, the linkage screw drives the sleeve block to move rightward under the action of the thread driving force. The produced stainless steel wire can perform tension sensing on the tension sensor, apply a specified tension to the produced stainless steel wire to achieve detection in different directions, and the detection applicability is wider.

[0014] 2. Through the auxiliary rolling component of the utility model, during the offset pulling process of the produced stainless steel wire inside the concave strip, the produced stainless steel wire will contact the side roller. The connecting shaft rotates on the concave strip, the flat roller drives the rotating shaft to rotate, and the rotating shaft rotates inside the socket shaft block to ensure that the produced stainless steel wire makes rolling contact, reducing the friction force detected by the produced stainless steel wire.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] As shown in the attached Figures 1-5 tensile testing device for stainless steel wire production. A displacement detection component is provided on the tensile testing device for stainless steel wire production. The setting of the displacement detection component can perform tensile sensing on the produced stainless steel wire on the tensile sensor 12, apply a specified tensile force to the produced stainless steel wire to achieve detection in different directions, and the detection applicability is wider. The specific structure of the displacement detection component is set as follows.

[0023] In this embodiment, as shown in the attached Figures 1-3 figure, a sliding frame 2 is welded on one side of the box body 1. A sleeve block 3 is slidably connected to the inner wall of the sliding frame 2. The top of the sleeve block 3 is equipped with a displacement detection component; the displacement detection component includes an offset frame 4 fixedly installed at the top of the sleeve block 3, and a positioning screw 5 is welded to the bottom end of the inner wall of the offset frame 4. A nut 6 is threadedly connected to the outer wall of the positioning screw 5; a linkage screw 7 is threadedly connected to the inner wall of the sleeve block 3, and a driving motor 8 is fixedly installed at one end of the sliding frame 2. The driving motor 8 is used to drive the linkage screw 7 to rotate.

[0024] One side of the offset frame 4 is provided with a sliding plate 9 fixedly connected to the box body 1. A socket block 10 is welded on one side of the sliding plate 9. A tensile electric cylinder 11 is fixedly installed on one side of the socket block 10. The contraction end of the tensile electric cylinder 11 is fixedly installed with a tensile sensor 12, and a concave strip 13 is fixedly connected to the sensing end of the tensile sensor 12. The output end of the driving motor 8 is fixedly connected to the linkage screw 7, and the outer wall of the linkage screw 7 is rotatably connected to the sliding frame 2. The lower surface of the offset frame 4 is slidably connected to the box body 1, and the upper surface of the box body 1 and the outer wall of the offset frame 4 are both smooth surfaces.

[0025] In this embodiment, as shown in the attached Figures 3-4 figure, two hinged doors 14 are hinged on the inner wall of the box body 1. There is a gap between the two hinged doors 14 to facilitate opening the two hinged doors 14 for maintenance operations inside the box body 1. A pulling screw 20 is welded to the bottom end of the inner wall of the concave strip 13, and an extrusion nut 21 is threadedly connected to the outer wall of the pulling screw 20; both the extrusion nut 21 and the pulling screw 20 are made of stainless steel material to facilitate winding the produced stainless steel wire around the outer wall of the pulling screw 20. By rotating the extrusion nut 21, the extrusion nut 21 and the pulling screw 20 move downward under the action of the threaded driving force, so that the extrusion nut 21 squeezes the produced stainless steel wire for fixation, firmly realizing the fixed detection of the produced stainless steel wire.

[0026] When the tensile testing device for stainless steel wire production in this technical solution is in use, the produced stainless steel wire is wound around the outer wall of the positioning screw 5. By rotating the nut 6, the nut 6 moves downward under the action of the thread driving force between the nut 6 and the positioning screw 5, and the stainless steel wire can be pressed and fixed by the nut 6 squeezing the stainless steel wire. At the same time, the produced stainless steel wire is wound around the outer wall of the pulling screw 20. By rotating the extrusion nut 21, the extrusion nut 21 moves downward under the action of the thread driving force with the pulling screw 20, so that the extrusion nut 21 squeezes the produced stainless steel wire for fixation.

[0027] By starting the tensile electric cylinder 11 to drive the tensile sensor 12 to move rightward, the box body 1 supports the sliding plate 9, and the sliding plate 9 supports the tensile electric cylinder 11. In this way, the tensile sensor 12 drives the concave strip 13 to move rightward, and the concave strip 13 drives the pulling screw 20 to move rightward. The pulling screw 20 drives the produced stainless steel wire to move rightward and be pulled, so that the produced stainless steel wire is pulled on the positioning screw 5. By starting the driving motor 8 to drive the linkage screw 7 to rotate forward, the linkage screw 7 drives the sleeve block 3 to move rightward under the action of the thread driving force. The sleeve block 3 moves rightward along the inner wall of the sliding frame 2. The sleeve block 3 drives the offset frame 4 to move rightward, and the offset frame 4 drives the positioning screw 5 to move rightward. The positioning screw 5 drives the produced stainless steel wire to move rightward and be pulled. Then, by driving the driving motor 8 to drive the linkage screw 7 to rotate reversely, the linkage screw 7 drives the sleeve block 3 to move leftward under the action of the thread driving force. The sleeve block 3 drives the offset frame 4 to move leftward, and the offset frame 4 drives the positioning screw 5 to move leftward. The positioning screw 5 drives the produced stainless steel wire to move leftward, so that the produced stainless steel wire can perform tensile sensing on the tensile sensor 12.

[0028] In this embodiment, as shown in the appendix Figures 3-5 As shown, an auxiliary rolling component is installed at the top end of the inner wall of the box body 1; the auxiliary rolling component includes two connecting shafts 15 rotatably installed at the top end of the inner wall of the box body 1. A side roller 16 is welded to the bottom end of each connecting shaft 15, and the side roller 16 is rotatably connected to the concave strip 13; the auxiliary rolling component further includes a socket shaft block 17, a rotating shaft 18, and a flat roller 19; the socket shaft block 17 is fixedly connected to one side of the concave strip 13, the rotating shaft 18 is rotatably connected to the inner wall of the socket shaft block 17, and the flat roller 19 is fixed to one end of the rotating shaft 18. The outer walls of the two side rollers 16 are smooth surfaces, and the cross-section of the side roller 16 is circular.

[0029] When this technology is in use, during the process of the produced stainless steel wire offsetting and being pulled inside the concave strip 13, the produced stainless steel wire will contact the side roller 16. The side roller 16 drives the connecting shaft 15 to rotate, and the connecting shaft 15 rotates on the concave strip 13. At the same time, the produced stainless steel wire rolls on the flat roller 19, and the flat roller 19 drives the rotating shaft 18 to rotate. The rotating shaft 18 rotates inside the socket shaft block 17. In this way, the produced stainless steel wire can achieve multi-directional rolling friction, avoiding frictional damage to the produced stainless steel wire, and thus avoiding affecting and directly scraping and damaging the produced stainless steel wire.
