Description
Technical Field
[0001] The utility model relates to the field of metal surface treatment, in particular to a metal surface rust removal device. Background Technique
[0002] Metal surface rust removal is a technology that uses chemical, electrochemical, mechanical and other methods to remove oxides on the surface of equipment and its components. Rust removal with rust solution mainly involves brushing or soaking a weakly acidic chemical liquid (i.e., rust removal solution) on the rusty metal surface, which is not likely to cause excessive corrosion to the metal surface.
[0003] When the workpiece is inserted into the rust removal solution, various clamps are needed to hold it, which makes it difficult for the clamped part of the workpiece to come into contact with the rust removal solution. Moreover, the generated precipitates and impurities are likely to accumulate in the rust removal solution, making it inconvenient to clean. Furthermore, the precipitates and impurities generated by the rust and the rust removal solution will cover the rust, making it difficult for the inner-layer rust to come into contact with the rust removal solution. Content of the Utility Model
[0004] In order to overcome the disadvantages that when the traditional device removes rust, it is difficult for the clamped part of the workpiece to come into contact with the rust removal solution, and the generated precipitates and impurities are likely to accumulate in the rust removal solution, making it inconvenient to clean. At the same time, the precipitates and impurities generated by the rust and the rust removal solution will cover the rust, making it difficult for the inner-layer rust to come into contact with the rust removal solution, the utility model provides a metal surface rust removal device that can make the clamped part of the workpiece also come into contact with the rust removal solution, is convenient to clean the precipitates and impurities in the rust removal solution, and can also scrape off the precipitates and impurities covering the rust, so that the inner-layer rust can also come into contact with the rust removal solution.
[0005] The technical solution is as follows: A metal surface rust removal device includes a chassis. A cylinder is fixedly connected to the chassis. A liquid outlet valve is fixedly connected to the bottom of the cylinder. An electric push rod is provided on one side of the chassis. The top of the telescopic rod of the electric push rod is fixedly connected to a connecting frame. A filtering frame is fixedly connected to the lower part of the connecting frame. The filtering frame is located inside the cylinder and is slidably connected to the cylinder.
[0006] As a further preferred solution, it further includes a placement rack. Two placement racks are provided inside the filtering frame. A placement groove is opened on each placement rack. A workpiece is placed between the placement grooves of the two placement racks.
[0007] As a further preferred solution, it further includes a limiting frame. The limiting frame is fixedly connected to the side of the chassis away from the placement rack. A guiding frame is slidably connected to the bottom of the filtering frame. The top of the guiding frame contacts the limiting frame. A threaded rod is fixedly connected to one side of the guiding frame. The threaded rod is slidably connected to the filtering frame.
[0008] As a further preferred solution, it further includes a mounting bracket. Two mounting brackets are fixedly connected inside the filtrate frame. A nut sleeve is slidably connected between the two mounting brackets. The nut sleeve is threadedly connected to the threaded rod. A rotating wheel is fixedly connected to the nut sleeve. The rotating wheel contacts one side of the workpiece. The rotating wheel is located between the two mounting brackets.
[0009] As a further preferred solution, it further includes a tool rest. Two tool rests are provided at the bottom of the filtrate frame. Two scraping knives are provided on each tool rest. The scraping knives contact the workpiece. Two groups of return springs are provided between the scraping knives and the tool rest. Each group of return springs consists of two springs.
[0010] As a further preferred solution, it further includes rollers. Two rollers are provided inside each placement rack.
[0011] The utility model has the following advantages: 1. By the operator adjusting the telescopic rod of the electric push rod to extend, the extension of the telescopic rod of the electric push rod drives the connecting frame to move upward and reset. The upward movement and reset of the connecting frame drive the filtrate frame to move upward. The upward movement and reset of the filtrate frame drive the placement rack to move upward. The upward movement and reset of the placement rack drive the workpiece to move upward. The workpiece moves upward until it is separated from contact with the rust removal liquid. The operator takes the workpiece out of the placement rack and clears the sediment and impurities in the filtrate frame. Through the above operations, it is more convenient for the operator to clean the sediment and impurities in the rust removal liquid.
[0012] 2. When the filtrate frame moves downward, it drives the guide frame and the mounting bracket to move downward. When the guide frame moves downward until it contacts the bottom of the cylinder, it stops moving downward. Under the action of the thread, the nut sleeve will rotate. The rotation of the nut sleeve drives the rotating wheel to rotate. The rotation of the rotating wheel drives the workpiece to move horizontally in the placement groove of the placement rack, so that the clamped part of the workpiece also contacts the rust removal liquid, avoiding incomplete rust removal due to the clamped part not contacting the rust removal liquid, thus achieving the effect of sufficient rust removal.
[0013] 3. When the workpiece moves horizontally in the placement groove of the placement rack, the scraping knife will scrape off the sediment and impurities on the metal surface, so that the workpiece will not have incomplete rust removal due to the surface being covered by sediment and the rust not being able to continue to contact the rust removal liquid.
