Description

Technical Field

[0001] This utility model relates to the field of cold-rolled aluminum coil technology, and in particular to a device for measuring the elongation of cold-rolled aluminum coil. Background Technology

[0002] Cold-rolled aluminum coils are an important product in the aluminum processing industry. Elongation is a key indicator for measuring the mechanical properties of cold-rolled aluminum coils, directly affecting the forming effect and product quality in subsequent processing. Therefore, precise measurement of elongation is necessary during the production of cold-rolled aluminum coils to ensure that the products meet usage requirements.

[0003] In existing technologies, the elongation measurement of cold-rolled aluminum coils is mostly achieved using a universal testing machine with a clamping device. This involves fixing the aluminum coil sample and stretching it, then calculating the elongation by measuring the length change before and after stretching. However, in actual production, to comprehensively evaluate the mechanical properties of cold-rolled aluminum coils, samples of different lengths and widths need to be selected for testing. However, fixed clamps can only clamp and fix a portion of the aluminum coil, resulting in poor flexibility. When dealing with aluminum coils that cannot be clamped, specific clamps need to be replaced, making the operation cumbersome and severely impacting the testing efficiency of aluminum coils.

However, in actual production, to comprehensively evaluate the mechanical properties of cold-rolled aluminum coils, samples of different lengths and widths need to be selected for testing. However, fixed clamps can only clamp and fix a portion of the aluminum coil, resulting in poor flexibility. When dealing with aluminum coils that cannot be clamped, specific clamps must be replaced, making the operation cumbersome and severely impacting the testing efficiency of the aluminum coils.

[0006] As a further embodiment of this utility model, the surfaces of the slide rail and the slider are provided with a number of threaded holes, one of which is internally threaded with a positioning bolt. The positioning bolt serves to fix the slider.

[0007] As a further embodiment of this utility model, limit holes are provided on both sides of the threaded plate, and limit rods are slidably connected inside the limit holes. The limit rods serve to limit the movement of the threaded plate.

[0008] As a further embodiment of this utility model, the limiting rod is fixedly connected to both sides of the top plate. The limiting rod is made of stainless steel, and the top plate serves to support the limiting rod on one side.

[0009] As a further embodiment of this utility model, a limiting groove is formed inside the mounting plate, and a positioning rod is slidably connected inside the limiting groove. The positioning rod serves to position the mounting plate.

[0012] (III) Beneficial Effects This utility model provides a device for measuring the elongation of cold-rolled aluminum coils, which has the following advantages: 1. This cold-rolled aluminum coil elongation measuring device, through the clamping mechanism, allows for the activation of an electric push rod on one side based on the length and width of the sampled aluminum coil. The electric push rod moves the lower pressure pad to a suitable position, ensuring the aluminum coil is directly beneath the pressure pad. Then, the slider on the slide rail is moved to accommodate the width of the aluminum coil, and a positioning bolt secures the adjusted slider. Finally, the threaded rod on one side of the slider is tightened. This threaded rod, via a rotating shaft at the bottom, drives the lower pressure pad below the rotating shaft to fix the aluminum coil directly beneath it. This achieves the effect of fixing aluminum coils of different lengths and widths, improving the flexibility and versatility of the equipment during use.

[0013] 2. This cold-rolled aluminum coil elongation measuring device, through the setting of the measuring mechanism, when in use, starts the drive motor on the top side, which drives the lead screw on the output end to rotate. This causes the threaded plate connected to the threaded plate to move left and right along the surface of the lead screw under the limitation of the limit rods on both sides. This causes the laser rangefinder below the threaded plate to move left and right on the lead screw. The laser rangefinder detects the length of the aluminum coil before and after stretching, and transmits the detected data to the PLC controller on one side for display. This achieves the effect of accurate distance measurement and convenient acquisition of elongation, eliminating the need for manual operation by staff using external measuring tools, thus improving the efficiency of aluminum coil elongation measurement.

The clamping mechanism 3 includes an electric push rod 301 fixedly connected to one side of the upright plate 2. A battery 11 is electrically connected to one side of the electric push rod 301 via a power cord. The battery 11 is installed on the surface of the electric push rod 301.

A connecting plate 305 is fixedly connected to one side of the slider 304. A threaded rod 306 is threadedly connected to the surface of the connecting plate 305. A rotating shaft 307 is rotatably connected to the bottom, and a lower pressure pad 308 is fixedly connected to the bottom of the rotating shaft 307; the measuring mechanism 7 includes a drive motor 701 fixedly connected to one side of the extension plate 6, a lead screw 702 fixedly connected to the output end of the drive motor 701, a threaded plate 703 threadedly connected to the surface of the lead screw 702, limit holes are opened on both sides of the threaded plate 703, and a limit rod 9 is slidably connected inside the limit holes; a laser rangefinder 704 is installed at the bottom of the threaded plate 703, and a PLC controller 705 is electrically connected to one side of the laser rangefinder 704 via a power line; Furthermore, the limiting rod 9 is fixedly connected to both sides of the top plate 5, and the limiting rod 9 is made of stainless steel.

[0018] In this invention, the working steps of the device are as follows: First step: When using the device, depending on the length and width of the sampled aluminum coil, the electric push rod 301 on one side can be activated. The electric push rod 301 drives the lower pressure pad 308 to move to the appropriate position, so that the aluminum coil can be located directly under the lower pressure pad 308.

This causes the laser rangefinder 704 below the threaded plate 703 to move left and right on the lead screw 702. The laser rangefinder 704 detects the length of the aluminum coil before and after stretching and transmits the detected data to the PLC controller 705 on one side for display.
