Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of corrosion resistance testing, specifically to a corrosion resistance testing device for coated metal materials. Background Technology
[0002] Metal coating refers to the process of covering the surface of a metal substrate with one or more layers of other metal or non-metal materials. This technology is widely used in various fields, including materials processing, machinery manufacturing, and electronic devices. Before leaving the factory, metal materials need to be subjected to corrosion resistance tests to ensure the subsequent performance of the metal materials.
[0003] For example, Chinese utility model patent CN209821033U discloses a metal material surface corrosion resistance testing device, including a base and a fixing frame. A cleaning tank is formed in the center of the upper surface of the base, and fixing clamps are provided at both ends of the upper side of the cleaning tank. Connecting shafts are fixed to the outer ends of the fixing clamps, and the fixing frame is located on the upper side of the fixing clamps. This metal material surface corrosion resistance testing device not only facilitates the fixing and testing of metal blocks but also avoids safety hazards to operators from testing reagents.
[0004] However, the existing devices mentioned above cannot simultaneously clamp multiple metal materials of different thicknesses and sizes, which reduces the efficiency of the device for testing metal materials and has certain limitations. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a corrosion resistance testing device for coated metal materials, which facilitates simultaneous clamping and fixing operations for metal materials of different thicknesses, improves the range and efficiency of metal material testing, and enhances the practicality of the device.
[0006] This utility model discloses a corrosion resistance testing device for coated metal materials, comprising a test chamber, a door installed on the outer wall of the test chamber, a water inlet pipe connected to the top of the test chamber, a drain pipe connected to the bottom of the test chamber, and a support mechanism installed inside the test chamber; the support mechanism includes a support plate, multiple pillars fixedly installed around the top of the support plate, the top of each pillar being fixedly connected in pairs by connecting rods, wherein multiple limiting rods are fixedly installed parallel between two opposing connecting rods, a connecting plate is fixedly installed at the bottom of each limiting rod, and a clamping mechanism is provided on each limiting rod;
[0007] The clamping mechanism includes a limiting block, a limiting groove is provided at the bottom end of the limiting block, the limiting groove slides and fits in contact with the top end of the limiting rod, and a clamping plate is fixedly installed on the outer side wall of the limiting block by an inclined plate, the clamping plate fits tightly in contact with the outer side wall of the connecting plate.
[0008] Each limiting block is equipped with a limiting mechanism. This corrosion resistance testing device for coated metal materials uses a support plate to initially support the bottom of the metal material, a connecting plate to adhere to the outer wall of the metal material, and a limiting mechanism to drive the limiting blocks to move laterally. The limiting groove at the bottom of the limiting block adheres to the limiting rod and slides, thereby synchronously driving the inclined plate and clamping plate to move. The clamping plate and connecting plate clamp metal materials of different thicknesses, facilitating simultaneous clamping and fixing of metal materials of different thicknesses. This improves the range and efficiency of the device for testing metal materials and enhances its practicality.
[0009] Preferably, the limiting mechanism includes two upright plates, which are respectively fixedly installed on the outer walls of two limiting rods located on both sides. A first screw is rotatably installed between the two upright plates. A lifting plate is slidably installed on the top of each limiting block. Each lifting plate is screwed to the first screw. The lifting plate is moved laterally while the first screw rotates. The lifting plate slides with the limiting block, which facilitates the longitudinal and lateral movement of the limiting block for metal materials of different thicknesses. The limiting groove at the bottom of the limiting block slides and fits against the top of the limiting rod. The clamping plate is then driven synchronously by the inclined plate to fix the metal material on the outer wall of the connecting plate.
[0010] Preferably, a bracket is obliquely fixedly installed at the top of each connecting rod, and the top of each bracket is fixedly connected by a fixing plate. A second screw is rotatably installed at the top of the fixing plate and screwed to the top of the test chamber. By rotating the second screw, the bracket, fixing plate, connecting rod, support column and support plate are simultaneously driven to move longitudinally, thereby allowing the metal material fixed on the connecting plate to be immersed in the liquid inside the test chamber.
[0011] Preferably, multiple limiting posts are symmetrically fixedly installed at the bottom of the test chamber. The inner sidewall of each limiting post is slidably connected to the outer sidewall of each support column. By installing the limiting posts, it is convenient to effectively limit the support column of the sliding operation.
[0012] Preferably, the top of the support plate has multiple bottom grooves that are parallel to each other. By opening the bottom grooves, it is convenient to support and limit the bottom area of the metal material.
[0013] Preferably, the outer sidewalls of the support plate and each connecting plate are provided with a plurality of first through holes and second through holes, which facilitates the effective immersion of the metal by the liquid.
[0014] Preferably, a transparent scale plate is installed on the outer wall of the test chamber, which facilitates the observation of the immersion solution inside the test chamber.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This corrosion resistance testing device for coated metal materials provides initial support to the bottom of the metal material through a support plate, adheres to the outer wall of the metal material through a connecting plate, moves the limiting block laterally through a limiting mechanism, and slides the limiting rod through the limiting groove at the bottom of the limiting block, thereby synchronously moving the inclined plate and clamping plate. The clamping plate and connecting plate clamp metal materials of different thicknesses, facilitating synchronous clamping and fixing of metal materials of different thicknesses, improving the range and efficiency of the device for testing metal materials, and enhancing its practicality.

[0024] Each limiting block 10 is equipped with a limiting mechanism, which includes two upright plates 14.
