What are the disassembly methods of spring machine parts?

Posted by Admin
When using the spring machine, it is necessary to disassemble, inspect and repair the spring machine to ensure the service life of the spring machine. Let's take a look at the disassembly method of the spring machine parts.

(1) Interference connector
When disassembling interfering parts, appropriate disassembly tools and methods should be selected according to the matching size and interference amount of the parts. According to the degree of tightness, from loose to tight, use a wooden hammer, copper rod, hand hammer or sledgehammer, puller, etc. to disassemble in turn. If the interference is too large or to protect the mating surface, the workpiece can be heated or cooled, and then pressed out quickly. Regardless of the method of disassembly, check whether there are additional fixing or positioning devices, such as positioning pins, screws, etc., if any, must be removed first. The place where the force is applied should be correct, the force should be applied evenly, and the direction should be correct.

(2) Disassembly of rolling bearing
When disassembling the rolling bearing of the spring machine, in addition to the disassembly point of the interference connector, you should also pay attention not to use the rolling body to transmit force; when disassembling the shaft end bearing, you can use a copper rod or soft metal or wooden rod smaller than the inner diameter of the bearing to press the shaft end , place the spacer under the bearing, using a hammer.

(3) Removal of non-removable connections
Welded parts can be disassembled by sawing, flat chisel, small drill and drilling a row of holes and then chisel or sawing, gas cutting and other methods. Riveted parts can be removed by chiseling, sawing, gas cutting rivet heads, or drilling rivets with a drill. Disassembly mainly refers to the disassembly of the spring machine connector. In addition to the above rules, the method of disassembly and assembly should also be mastered.
