Cut acidic fruits in half, lemons flywheel wrench and oranges are fine. Coat the cut surface with a thick layer of coarse salt. Use lemon coated with coarse salt and wipe back and forth on the rust layer. After removing the rust layer, clean the ratchet wrench. Soak the rusty tire cross wrench in a mixed solution of water and baking soda for 5 to 10 minutes, take it out and wash it off with water. You can also add baking soda with water and stir to make a paste. Apply the paste directly on the rust layer and wipe it off when it dries. Soak the rusty ratchet wrench in a carbonated drink. After the bubbles disappear, you can take out the ratchet wrench. The rust layer on the surface is very clean, but the ratchet wrench should be cleaned.Pour white vinegar in the basin, put the rusty ratchet wrench in the white vinegar and soak it for a while. Then use a rag or toothbrush to remove the surface rust. You can also directly moisten a cloth with white vinegar, and scrub back and forth on rusty items. After cleaning, rinse the remaining white vinegar on the ratchet wrench.


If you encounter a thick layer of rust, you can use abrasive tools to remove the rust layer. However, this situation may cause scratches on the metal surface, so use it with caution.To punch the tire wrench, press the female punch first. This is easy, but the more difficult is that the punch is flattened. You can wrap the top rod with paper and stuff it into the nut to ensure concentricity. You can also use a suitable small screw. The cap is glued to the nozzle to restrain the ejector rod. As long as the punch can be pushed into the nozzle a little bit, it is easy to do it. Slowly push it, push it to the bottom, remove the nut, replace with a longer ejector rod and continue to push it, lengthen it in turn, combine the ejector rods into different lengths, until the punch Finish. Pay attention to try to use the top of the ejector pin of about five centimeters on the top of the nozzle. You can also wrap paper on the ejector to enhance the concentricity. After the yin thread is punched, use a thin wire or a thin iron wire wrapped around a steel wire ball to polish the burrs on the tire wrench.


You can put some grinding powder to polish it well, so you are not afraid of hurting the thread. Tie the knot with a string, stick abrasive paste and polish it brightly. Finally, use the Yang line punch to punch the Yang line twice, so that the beautiful rifle will come out, and the dimensional accuracy of the Yin line and the Yang line is also very high.Through the analysis of the processing technology of the workpiece and the characteristics of the parts, the parts processing of the tire wrench can be completed by using flat-nose pliers. The through hole used to assemble the movable opening and the blind hole used to install the pulley shaft are more troublesome to process on the machining center. The general blade of the end mill with the same diameter as the hole diameter generally cannot meet the hole depth requirement. The drilling machine can be used for processing, which is more convenient for processing. Generally, end mills or face milling cutters are used when processing planes in CNC machining centers. End mills are generally used for milling of smaller planes, and face milling cutters are used for milling of larger planes.


In order to prevent the workpiece from displacing under the action of cutting force and keep it in the correct position during the machining process, it is necessary to clamp the workpiece firmly. It is very important to choose a reasonable clamping method. The clamping of the workpiece not only affects the processing quality, but also has a direct impact on productivity, processing costs and operational safety.The principle of easy clamping. The selected positioning reference should be able to ensure accurate and reliable positioning, simple positioning and clamping mechanism, easy operation, good openness, and capable of processing as many surfaces as possible. The outer contour of plate parts is mainly based on the symmetrical centerline. The coaxiality of the inner hole, thread and other surfaces, and the perpendicularity of the end face to the axis centerline are the main items of their mutual position accuracy, and the design basis of these surfaces is general. Both are shaft centerlines. The principle of facilitating knife setting. When the workpiece coordinate system has been determined during batch processing, the possibility and convenience of tool setting are guaranteed. The principle of benchmark coincidence. In order to avoid the misalignment error of the reference and facilitate programming, the process reference should be selected as the positioning reference, and the process reference, the positioning reference, and the programming origin should be unified as much as possible.
