Description

Technical Field

[0001] This utility model relates to the field of nickel-chromium wire quality testing technology, specifically to a nickel-chromium wire quality testing device. Background Technology

[0002] Commonly used heating materials are nickel-chromium alloys and iron-chromium alloys, used to manufacture heating elements in various resistance heating devices. The requirements for these materials are high resistivity, good machinability, sufficient mechanical strength at high temperatures, and good oxidation resistance. Nickel-chromium wire requires quality inspection during the production process.

[0003] Existing nickel-chromium wire quality testing devices generally can only perform tests one by one during the testing process. For example, in the Chinese Patent Document Database, patent application number 202320062484.7 discloses a nickel-chromium wire quality testing device. When testing the tensile performance, it is necessary to fix both ends of the nickel-chromium wire first, and then move it through a linear drive to perform the tensile test. In order to avoid the ends of the nickel-chromium wire loosening during the tensile test, it takes a long time to fix the ends, resulting in low work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a nickel-chromium wire quality testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nickel-chromium wire quality inspection device, including an inspection chamber, inside which a movable plate is movably mounted up and down via a linear drive component, a tension gauge is installed at the top of the inspection chamber, and a fixed plate is installed at the bottom of the tension gauge, and mounting plates are detachably mounted on opposite sides of the movable plate and the fixed plate, and positioning components are threaded onto opposite sides of both mounting plates, with the two positioning components respectively used to fix both ends of the nickel-chromium wire.

[0006] Furthermore, the two mounting plates are horizontally slidably connected to the movable plate and the fixed plate respectively via limiting slide rails, and the ends of the movable plate and the fixed plate away from the mounting plates are each provided with limiting mechanisms for limiting the mounting plates.

[0007] Furthermore, the limiting mechanism includes a fixed rod, a horizontal plate that is movably sleeved on the fixed rod, a limiting plate fixed to the end of the fixed rod, and a plurality of positioning rods fixed on the horizontal plate. The mounting plate is provided with a through hole to accommodate the vertical movement of the positioning rods. A return spring is sleeved on the fixed rod to push the horizontal plate to move closer to the mounting plate, so that the positioning rods are inserted into the through hole on the mounting plate.

[0008] Furthermore, the positioning element includes a threaded rod that is threadedly connected to the mounting plate and a pressure plate fixed to one end of the threaded rod.

[0009] Furthermore, a waste trough is placed at the bottom of the detection cavity.

[0010] Furthermore, a movable door is movably provided on the front end face of the detection cavity.

[0011] Furthermore, the mounting plate is provided in multiple forms.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The nickel-chromium wire quality inspection device has a mounting plate that can be detachably installed at one end of the movable plate and the fixed plate. The mounting plate is threaded with a positioning component. By wrapping both ends of the nickel-chromium wire around the positioning component and then tightening the positioning component, the nickel-chromium wire can be pressed firmly onto the mounting plate, making the fixing more convenient, quick, and secure. At the same time, multiple mounting plates can be set, and inspection and feeding can be carried out simultaneously. After the inspection is completed, the mounting plate can be quickly removed and a new nickel-chromium wire to be inspected can be replaced, thereby improving the inspection efficiency.

[0018] Please see Figure 1-3 The present invention provides an embodiment of a nickel-chromium wire quality testing device, which includes a testing chamber 1. In this embodiment, the testing chamber 1 is a cuboid structure with an open front end, and a movable door 101 is movably provided on the front end of the testing chamber 1. A transparent observation window is provided on the movable door 101, which can clearly and intuitively observe the tensile test of the nickel-chromium wire, while avoiding accidental injury to the staff when the nickel-chromium wire breaks.

[0019] Inside the detection chamber 1, a movable plate 2 is vertically mounted via a linear drive 3. The linear drive 3 can be any type of hydraulic cylinder, pneumatic cylinder, or electric push rod. Furthermore, to improve the stability of the movable plate 2's vertical movement, a guide rod can be vertically installed inside the detection chamber 1. The movable plate 2 is slidably connected to the guide rod. A tension gauge 4 is installed at the top of the detection chamber 1 to detect the tension when stretching a nickel-chromium wire. A controller is also included to receive test signals. A fixed plate 5 is installed at the bottom of the tension gauge 4. Both the movable plate 2 and the fixed plate 5 can be detached from their respective sides. The mounting plates 6 are provided, and each of the two mounting plates 6 has a threaded positioning element 7 on one side facing each other. The two positioning elements 7 are used to fix the two ends of the nichrome wire. The positioning element 7 includes a threaded rod 701 that is threaded to the mounting plate 6 and a pressure plate 702 fixed to one end of the threaded rod 701. When fixing the end of the nichrome wire, the nichrome wire is first wound around the threaded rod 701, and then the positioning element 7 is rotated. The pressure plate 702 presses the nichrome wire wound on the threaded rod 701 tightly onto the mounting plate 6, which is more secure and reliable, and avoids the two free ends of the nichrome wire from loosening and detaching during the stretching process, which would affect the test.

[0020] The two mounting plates 6 are horizontally slidably connected to the movable plate 2 and the fixed plate 5 respectively via the limiting slide rail 8, and the ends of the movable plate 2 and the fixed plate 5 away from the mounting plate 6 are provided with limiting mechanisms 9 for limiting the mounting plate 6.

[0021] Specifically, the limiting mechanism 9 includes a fixed rod 903, a horizontal plate 901 that is movably sleeved on the fixed rod 903, a limiting plate 905 fixed to the end of the fixed rod 903, and two positioning rods 902 fixed on the horizontal plate 901. The mounting plate 6 has a through hole for accommodating the vertical movement of the positioning rods 902. A return spring 904 is sleeved on the fixed rod 903 to push the horizontal plate 901 to move closer to the mounting plate 6, so that the positioning rods 902 are inserted into the through hole on the mounting plate 6.

[0022] For details, please refer to the attached document. Figure 3 The limiting slide rail 8 is a T-shaped slide rail. The bottom end of the fixed plate 5 is provided with a slide groove that matches the limiting slide rail 8. The top end of the movable plate 2 is fixed with two limiting slide rails 8. The bottom end of the mounting plate 6 is provided with a slide groove that matches the limiting slide rail 8. When the mounting plate 6 is inserted into place, the through hole on the mounting plate 6 coincides with the positioning rod 902. By pulling the horizontal plate 901 up and down along the length of the fixed rod 903, the positioning rod 902 is moved up and down, so that it can be inserted into the through hole of the mounting plate 6 or separated from the mounting plate 6, thus quickly realizing the installation and removal of the mounting plate 6, which is convenient and quick.

[0023] Furthermore, multiple mounting plates 6 are provided, which can fix multiple nichrome wires at the same time. During testing, nichrome wires can be fixed on other mounting plates 6 simultaneously. After testing, the mounting plates 6 can be directly removed and installed, reducing waiting time and improving work efficiency.

[0024] Furthermore, a waste trough 10 is placed at the bottom of the detection chamber 1 to collect broken nickel-chromium wires for centralized processing after the detection is completed.

[0025] Working principle: The two ends of the nichrome wire to be tested are wound around the two threaded rods 701 respectively. Then, the positioning component 7 is rotated, and the pressure plate 702 presses the nichrome wire wound on the threaded rods 701 tightly onto the mounting plate 6 to prevent the ends of the nichrome wire from loosening during the tensile test and affecting the test. Next, the horizontal plate 901 is pulled, causing the horizontal plate 901 to compress the return spring 904. The two mounting plates 6 are then inserted into the opposite ends of the movable plate 2 and the fixed plate 5 respectively. After insertion, the horizontal plate 901 is released, and the return spring 904 pushes the horizontal plate 901 to return to its original position, allowing the positioning rod 902 to be inserted into the through hole on the mounting plate 6 for positioning. The movable plate 2 is driven up and down by the linear drive component 3 to perform a tensile test on the nichrome wire. The current tensile force is detected by the tension gauge 4. During the test, a new nichrome wire to be tested can be fixed to the mounting plate 6 and the positioning component 7. After a set of tests is completed, the mounting plate 6 can be quickly removed and a new fixed nichrome wire can be replaced, improving the testing efficiency.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
