Technical Field

[0001] This utility model belongs to the field of spring steel wire tensile testing technology, and in particular relates to a tensile testing device for aging-treated spring steel wire. Background Technology

[0002] After spring steel wire is drawn, it usually needs to be tested to determine its mechanical strength and tensile properties. Such tests generally use a wire tensile testing device to test various physical and mechanical properties of the steel wire. Currently, there are many different types of tensile testing machines on the market, such as the Chinese utility model patent with patent number "CN201821351043.4", which discloses a wire rope tensile testing machine. However, the existing technical solutions still have the following technical defects: 1. The structure is complex, making it inconvenient to install and position the steel wire; 2. The method of testing by driving the tension plate with a hydraulic cylinder is not only unstable, but also has large friction during the pushing process, which can lead to deviations in the test results. Utility Model Content

[0003] The purpose of this utility model is to provide a tensile testing device for aged spring steel wire, so as to solve the technical problems of inconvenience in installing and positioning steel wire in existing steel wire tensile testing devices, as well as unstable driving mode and inaccurate test results during tensile testing.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a tensile testing device for aging-treated spring steel wire, comprising a base, a slide and a fixed seat on the base, the fixed seat abutting against one end of the slide, a slide plate on the slide, a first clamping device on the slide plate, a drive mechanism for controlling the slide plate to move back and forth along the slide, a tension sensing component installed on the side of the fixed seat near the slide plate, and a second clamping device at one end of the tension sensing component.

[0005] Preferably, the slide has locking edges on both sides, a sliding groove is formed on the upper surface of the slide, the bottom of the slide plate has a sliding structure that moves in conjunction with the sliding groove, and the sides of the slide plate form straddles that are fixedly connected to the locking edges on both sides of the slide.

[0006] Preferably, the sliding structure is a guide wheel installed on the bottom surface of the slide plate, and the guide wheel is movably disposed in the slide groove.

[0007] Preferably, the sliding structure is a sliding part integrally formed on the bottom surface of the slide plate, and the sliding part is fitted in the slide groove and can drive the slide plate to move along the extension direction of the slide groove.

[0008] Preferably, the first clamping device includes a clamping mounting plate, on which a fixed clamping plate and a movable clamping plate are provided. The movable clamping plate is movable on the clamping mounting plate, and the movable clamping plate moves to one side of the fixed clamping plate through an adjusting component to achieve clamping.

[0009] Preferably, the first clamping device includes a tension clamp seat and a tension clamp sliding plate; the tension clamp sliding plate is located at the upper end of the tension clamp seat, the tension clamp sliding plate has a through hole inside, and the tension clamp sliding plate is fixed to the tension clamp seat by a sliding plate bolt.

[0010] Preferably, the driving mechanism is a driving cylinder, the driving end of the driving cylinder is located away from the slide plate, and a connecting plate is provided on the driving end. The connecting plate is fixedly connected to the slide plate by a number of extension rods.

[0011] Preferably, the two sides of the skateboard are integrally formed with mounting parts, and the two ends of the extension rod are respectively fixed to the connecting plate and the mounting parts. The connecting plate is driven to move back and forth by the drive cylinder and the extension rod is driven to drive the skateboard to slide back and forth on the slide platform.

[0012] Preferably, the tension sensing assembly includes a tension sensor and a digital display electrically connected to the tension sensor, the digital display being mounted on the mounting base.

[0013] Through the above technical solution, compared with the prior art, this utility model has the following beneficial effects: 1. By fixing a slide table on the base and setting a slide plate that can move along the horizontal extension direction of the slide table on the slide table, a first clamping device is provided on the slide plate, and a fixed seat that abuts against one side of the slide table is provided on the base, so that the slide plate can approach or move away from the fixed seat. At the same time, a tension sensing component is provided on the fixed seat, and a second clamping device is provided at the sensing position of the tension sensing component. In use, the distance between the fixed seat and the slide plate is adjusted according to the length of the spring steel wire. Then, the two ends of the spring steel wire are fixed between the slide plate and the fixed seat through the first clamping device and the second clamping device, respectively, and the ends of the spring steel wire are clamped and limited by the first clamping device and the second clamping device. Then, the drive mechanism is started. Since the drive end of the drive mechanism is fixed to the slide plate, when performing a tensile test, the drive mechanism will drive the slide plate to move on the slide table and gradually move away from the fixed seat. At this time, the tension sensing component installed on the fixed seat will sense the tension generated by the slide plate pulling the spring steel wire and display the tension on the digital display. In summary, the aforementioned driving structure and spring wire clamping and fixing method are not only simple in structure and convenient in operation, but also allow for adaptive position adjustment according to spring wires of different lengths. Furthermore, the clamping and fixing method facilitates the installation and use of spring wires, solving the technical problem of inconvenience in installing and positioning spring wires in existing steel wire tensile testing devices.

[0014] 2. The skateboard is secured to the sides of the slide platform via a straddle, and the sliding structure beneath the skateboard allows it to move back and forth along the sides of the slide platform, forming a straddle-type monorail motion structure. This mechanism not only limits the skateboard to the slide platform but also ensures its stability during movement, making it less prone to derailment and producing less noise. Furthermore, because the skateboard and the slide platform interact through the sliding structure, the friction between them is reduced, thereby improving the accuracy of the tensile sensor test results. This solves the technical problems of unstable drive mode and inaccurate test results in existing steel wire tensile testing devices during tensile testing. Attached Figure Description

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0027] like Figure 1-5 The first embodiment of this utility model is shown: a tensile testing device for aging-treated spring steel wire, including a base 1, a slide 2 and a fixed seat 3 on the base 1, the fixed seat 3 abutting against one end of the slide 2, a slide plate 4 on the slide 2, a first clamping device 8 on the slide plate 4, and a drive mechanism for controlling the slide plate 4 to move back and forth along the slide 2 on the base 1. A tension sensing component is installed on the side of the fixed seat 3 near the slide plate 4, and a second clamping device 9 is provided at one end of the tension sensing component.

[0028] In this embodiment, the slide 2 is fixed to the upper surface of the base 1 by a threaded connection, and the fixing seat 3 is fixed to the base 1 by welding or integral molding. The fixing seat 3 abutting against one side of the slide 2 increases its strength. The tension sensing component can be fixedly mounted on one side of the fixing seat 3. Specifically, a placement bracket is screwed to one side of the fixing seat 3, with the lower surface of the placement bracket contacting the upper surface of the slide 2. The tension sensing component is then mounted on the placement bracket and secured by threads to prevent it from coming loose. It should be noted that the tension sensing component can also be mounted on one side of the slide 2, abutting against the fixing seat 3. A control component is also included to control the operation of the drive mechanism.

[0029] like Figure 2-4 As shown: The slide table 2 has locking edges 201 on both sides, and a sliding groove 202 is provided on the upper surface of the slide table 2. The bottom of the slide plate 4 has a sliding structure that moves in conjunction with the sliding groove 202. The two sides of the slide plate 4 are formed with straddles 401 that are fixedly connected to the locking edges on both sides of the slide table 2. In this embodiment, there are two horizontally arranged sliding grooves 202 on the entire upper surface of the slide table 2. The two sides of the slide table 2 are integrally formed with locking edges 201. The two sides of the slide plate 4 are also formed with straddles 401. The straddles 401 are located below the slide plate 4. The inner side of the straddles 401 is formed with a groove that matches the locking edge 201. When the slide plate 4 is installed on the slide table 2, the locking edge 201 is located in the groove. The sliding plate 4 is firmly fixed on the slide table 2 by the cooperation of the locking edge 201 and the groove. The locking edge 201 can also play a guiding role.

[0030] The slide plate 4 is secured to the mounting edges 201 on both sides of the slide table 2 via the straddle 401. Combined with the sliding structure under the slide plate 4, the slide plate 4 can move back and forth along the mounting edges 201 on both sides of the slide table 2, forming a straddle-type monorail motion structure. This mechanism not only limits the slide plate 4 to the slide table 2 but also ensures the stability of the slide plate 4 during movement, making it less likely to derail when sliding, with less noise. Furthermore, because the slide plate 4 and the slide table 2 interact through the sliding structure, the friction between them is small, thereby improving the accuracy of the tensile sensor component test results. This solves the technical problems of unstable drive mode and inaccurate test results in existing steel wire tensile testing devices during tensile testing.

[0031] like Figure 3 As shown: The sliding structure is a sliding part 402 integrally formed on the bottom surface of the slide plate 4. The sliding part 402 is disposed in the slide groove 202 and can drive the slide plate 4 to move along the extension direction of the slide groove 202. In this embodiment, the sliding part 402 and the slide groove 202 move together. The above sliding method has a simple structure and strong stability.

[0032] The first clamping device 8 includes a clamp mounting plate, on which a fixed clamping plate and a movable clamping plate are provided. The movable clamping plate moves on the clamp mounting plate and moves to one side of the fixed clamping plate through an adjustment component to achieve clamping. This structure is existing technology and is mature, so it will not be described in detail here. The overall structure of the second clamping device 9 is the same as that of the first clamping device 8. The clamp mounting plate is fixed to the sensing end of the tension sensing component. The function of this structure is to clamp and fix both ends of the spring steel wire.

[0033] like Figure 1-2As shown: The driving mechanism is a driving cylinder 5. The driving end of the driving cylinder 5 is set away from the slide plate 4. A connecting plate 6 is provided on the driving end. The connecting plate 6 is fixedly connected to the slide 4 by several extension rods 7. In this embodiment, the driving end of the driving cylinder 5 is arranged in the opposite direction to the fixed base 3, and a connecting plate 6 is provided on it. Two extension rods 7 are provided on each of the left and right sides of the connecting plate 6. The slide 4 and the connecting plate 6 are connected by these extension rods 7, so that the slide 4 can be driven to move more stably when the driving cylinder 5 is started.

[0034] like Figure 4 As shown: The two sides of the slide plate 4 are integrally formed with mounting parts 403. The mounting parts 403 are integrally formed on both sides of the slide plate 4 to increase the connection strength. The two ends of the extension rod 7 are respectively fixed on the connecting plate 6 and the mounting parts 403. The connecting plate 6 is driven to move back and forth by the drive cylinder 5 and driven by the extension rod 7 to drive the slide plate 4 to slide back and forth on the slide table 2. The mounting part 403 is provided with a connecting end for fixing the extension rod 7. The two ends of the extension rod 7 are fixed between the mounting part 403 and the connecting plate 6 by threaded connection.

[0035] like Figure 5 As shown: The tension sensing assembly includes a tension sensor 10 and a digital display 11 electrically connected to the tension sensor 10. The digital display 11 is mounted on the fixed base 3. By setting the digital display 11, the intensity of the tension can be displayed in real time, thereby obtaining the required experimental data more quickly.

[0036] The second embodiment of this utility model: The difference between this embodiment and the first embodiment is that the sliding structure is a guide wheel installed on the bottom surface of the slide plate 4. The guide wheel is movably arranged in the slide groove 202. In this embodiment, by setting two sets of guide wheels on the bottom surface of the slide plate 4, the guide wheels and the bottom surface of the slide groove are in contact. By using the guide wheels to drive the slide plate 4 to move, the friction between the two can be reduced, making the movement of the slide plate 4 smoother and the measured tension data more accurate.

[0037] The first clamping device 8 includes a tension clamp seat and a tension clamp sliding plate; the tension clamp sliding plate is located at the upper end of the tension clamp seat, and a through hole is provided inside the tension clamp sliding plate. The tension clamp sliding plate is fixed to the tension clamp seat by a sliding plate bolt.

[0038] The working principle is as follows: A slide 2 is fixed on the base 1, and a slide plate 4 that can move along the horizontal extension direction of the slide 2 is set on the slide 2. The slide plate 4 is equipped with a first clamping device 8. At the same time, a fixed seat 3 is set on the base 1 against one side of the slide 2, so that the slide plate 4 can approach or move away from the fixed seat 3. The fixed seat 3 is equipped with a tension sensing component, and a second clamping device 9 is set at the sensing position of the tension sensing component. In use, the distance between the fixed seat 3 and the slide plate 4 is adjusted according to the length of the spring steel wire. Then, the two ends of the spring steel wire are separated. The spring wire is fixed between the slide plate 4 and the fixed base 3 by the first clamping device 8 and the second clamping device 9, which clamp and limit the end of the spring wire. Then, the drive mechanism is activated. Since the drive end of the drive mechanism is fixed to the slide plate 4, during the tensile test, the drive mechanism will move the slide plate 4 on the slide table 2 and gradually move it away from the fixed base 3. At this time, the tension sensing component installed on the fixed base 3 will sense the tension generated by the slide plate 4 pulling the spring wire and display the tension on the digital display. In summary, the above-mentioned drive structure and spring wire clamping and fixing method are not only simple in structure and convenient in operation, but also allow for adaptive position adjustment according to spring wires of different lengths. Furthermore, the clamping and fixing method makes it easier to install and use the spring wire, solving the technical problem of inconvenience in installing and positioning the spring wire in existing steel wire tensile testing devices.

[0039] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
