Description

Technical Field

[0001] This utility model relates to the field of tensile testing technology, and more specifically, to a tensile testing device for alloy wire. Background Technology

[0002] Alloy wires require specific tensile strengths for different applications. Tensile testing equipment can accurately measure the maximum tensile force that alloy wires can withstand during the stretching process, determine whether they meet the design strength standards, and prevent breakage due to insufficient strength during use, which could lead to serious accidents.

[0003] During the tensile testing of alloy wire, both ends of the alloy wire need to be fixed. However, the fixing process involves single-sided contact compression and locking, which makes it difficult to fix the alloy wire at multiple points and over a large area. This easily leads to slippage of the alloy wire during the tensile testing process, resulting in poor stability of the tensile test. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a tensile testing device for alloy wire, comprising a mounting plate, a grooved rail fixedly connected to the upper surface of the mounting plate, two sliding frames provided on the outer wall of the grooved rail, one sliding frame being slidably connected to the grooved rail, and the other sliding frame being fixedly connected to the grooved rail, the inner wall of the sliding frame being provided with a cover locking assembly, the cover locking assembly comprising:

[0005] A middle pressure plate is slidably inserted into the inner wall of the sliding frame. The inner wall of the middle pressure plate has multiple holes. A linkage block is fixedly connected to the upper surface of the middle pressure plate. Side pressure plates are provided on both sides of the middle pressure plate. Both side pressure plates are fixedly connected to the linkage block.

[0006] The bottom pressure plate is located below the side pressure plate. Both bottom pressure plates are fixedly connected to the sliding frame. The upper surface of the bottom pressure plate has multiple grooves.

[0007] In a preferred embodiment, the two side pressure plates are symmetrically arranged about the middle pressure plate, and the lower surface of the side pressure plates is provided with a friction surface.

[0008] In a preferred embodiment, the two bottom pressure plates are symmetrically arranged about the sliding frame, and the vertical cross-sectional shape of the groove is an arc.

[0009] The vertical cross-sectional shape of the hole is circular, and the inner wall of the hole and the inner wall of the groove are both smooth surfaces.

[0010] In a preferred embodiment, an electric cylinder is fixedly installed on one side of the inner wall of the groove rail, and a pressure sensor is fixedly connected to the output end of the electric cylinder;

[0011] The pressure sensor is fixedly connected to the sliding frame.

[0012] In a preferred embodiment, a socket block is installed on the upper surface of the intermediate pressure plate and near both ends thereof;

[0013] The inner wall of the socket block is slidably connected to a guide post, and a support block is fixedly installed at the bottom end of the guide post. The support block is fixedly connected to the sliding frame.

[0014] A threaded sleeve is fixedly installed at the top of the guide post, and a bolt is threadedly connected to the inner wall of the threaded sleeve.

[0015] In a preferred embodiment, the inner wall of the socket block and the outer wall of the guide post are both smooth surfaces, and the support block is used to support the guide post.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 - Figure 4 The device shown is a tensile testing device for alloy wire. The device is equipped with a cover locking assembly. The cover locking assembly can simultaneously lock the middle and both sides of the end of the alloy wire, making the alloy wire more secure and preventing the alloy wire from slipping and falling off during tensile testing. The specific structure of the cover locking assembly is as follows.

[0027] In this embodiment, as Figure 1 - Figure 3 As shown, a grooved rail 2 is fixedly connected to the upper surface of the mounting plate 1. Two sliding frames 3 are provided on the outer wall of the grooved rail 2. One sliding frame 3 is slidably connected to the grooved rail 2, and the other sliding frame 3 is fixedly connected to the grooved rail 2. A cover locking assembly is provided on the inner wall of the sliding frame 3. The cover locking assembly includes: a middle pressure plate 4, which is slidably inserted into the inner wall of the sliding frame 3. Multiple holes 5 are provided on the inner wall of the middle pressure plate 4. A linkage block 6 is fixedly connected to the upper surface of the middle pressure plate 4, and side pressure plates 7 are provided on both sides of the middle pressure plate 4. Both side pressure plates 7 are fixedly connected to the linkage block 6. A bottom pressure plate 8 is located below the side pressure plates 7. Both bottom pressure plates 8 are fixedly connected to the sliding frame 3. Multiple grooves 9 are provided on the upper surface of the bottom pressure plate 8. The two side pressure plates 7 are symmetrically arranged about the middle pressure plate 4, and a friction surface is provided on the lower surface of the side pressure plates 7. Two bottom pressure plates 8 are symmetrically arranged about the sliding frame 3. The vertical cross-section of the groove 9 is arc-shaped. The vertical cross-section of the hole 5 is circular. The inner wall of the hole 5 and the inner wall of the groove 9 are both smooth surfaces.

[0028] In this embodiment, as Figure 3As shown, an electric cylinder 10 is fixedly installed on one side of the inner wall of the groove rail 2, and a pressure sensor 11 is fixedly connected to the output end of the electric cylinder 10. The pressure sensor 11 is fixedly connected to the slide frame 3 so that the output end of the electric cylinder 10 can drive the pressure sensor 11 to move to the right, and the pressure sensor 11 can drive the slide frame 3 to move to the right, so that the guide column 13 and the slide frame 3 can pull the alloy wire.

[0029] This technology is used in an alloy wire tensile testing device. During operation, multiple alloy wires are inserted at one end into the groove 9, then into the hole 5, and finally into another groove 9 on a bottom pressure plate 8. The other end of each alloy wire is inserted into a groove 9 on the other bottom pressure plate 8. Then, bolt 16 is rotated, engaging and locking with the threaded sleeve 15. Under the force of the threaded engagement, bolt 16 presses against the sleeve block 12, which in turn presses against the intermediate pressure plate 4. The sleeve block 12 slides down along the outer wall of the guide post 13, while the slide frame 3 supports the support block 14, the support block 14 supports the guide post 13, and the guide post 13 supports the threaded sleeve 15. In this way, the sleeve block 12 presses the middle pressure plate 4, and the middle pressure plate 4 drives the linkage block 6 to move down. The linkage block 6 drives the two side pressure plates 7 to move down. In this way, the middle pressure plate 4 is guided and pressed along the inner wall of the slide frame 3 to fix the middle of multiple alloy wires, and the side pressure plates 7 press the alloy wires. The alloy wires are along the groove 9, and the slide frame 3 supports the bottom pressure plate 8. The electric cylinder 10 is activated by a switch. The output of the electric cylinder 10 drives the pressure sensor 11 to move to the right. The pressure sensor 11 drives the sliding frame 3 to move to the right. The sliding frame 3 drives the middle pressure plate 4 to move to the right. In addition, the sliding frame 3 drives the bottom pressure plate 8 to move to the right. In this way, the middle pressure plate 4 and the side pressure plate 7 drive the alloy wire to be pulled. The pressure value is sensed by the pressure sensor 11 and viewed on the display screen on the switch. This pressure sensing and display technology is existing public technology and will not be described in detail. Secondly, the circuit is a parallel circuit, which is also an existing public circuit and will not be described in detail.

[0030] In this embodiment, as Figure 4 As shown, a sleeve block 12 is installed on the upper surface of the intermediate pressure plate 4 near both ends; a guide post 13 is slidably connected to the inner wall of the sleeve block 12, and a support block 14 is fixedly installed at the bottom end of the guide post 13, with the support block 14 fixedly connected to the sliding frame 3; a threaded sleeve 15 is fixedly installed at the top end of the guide post 13, and a bolt 16 is threadedly connected to the inner wall of the threaded sleeve 15. The inner wall of the sleeve block 12 and the outer wall of the guide post 13 are both smooth surfaces, and the support block 14 is used to support the guide post 13. The cross-sectional area of ​​the threaded sleeve 15 is larger than the cross-sectional area of ​​the support block 14, and the bolt 16 can be used to press and lock the sleeve block 12.

[0031] When this technology is used in the tensile testing equipment for alloy wires, the bolt 16 presses against the sleeve block 12 under the action of the thread meshing force, ensuring that the sleeve block 12 slides down along the outer wall of the guide post 13. The support block 14 supports the guide post 13, and the sleeve block 12 presses against the intermediate pressure plate 4. The intermediate pressure plate 4 drives the linkage block 6 to move down.

[0032] The electric cylinder 10 and pressure sensor 11, which are not described in detail in the instruction manual, are connected in parallel with the switch. Therefore, they are controlled separately in parallel. The parallel circuit is a common knowledge circuit, so the circuit is not described in detail and is known to those skilled in the art. The model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used. The electrical control components not mentioned in this technical solution are not shown in the figure because they are existing technology, and will not be described here.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
