At the same time, when the cone crusher is working, the movable cone liner will expand, which will generate greater stress or tension on the locking bolts, resulting in damage or loosening of the locking bolts.
Once the moving cone liner is loose, it will damage the moving cone and the main shaft of the cone crusher, resulting in the scrapping of the equipment

Embodiment Construction
[0024] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0025] see Figure 1-5 , after the removal and replacement of the OM and HP series cone crusher cone liners, the positioning is as follows figure 1 As shown, it involves figure 1 The welding between the locking bolt 1 of 45# shown, the cast steel ZGMn13 part 2 of the movable cone liner and the cutting ring 3 of 45# steel is shown.
[0026] Its welding method, it comprises the following steps:
[0027] (1) Clean up the dirt, oil and rust at the welding joints of cutting ring 2, locking bolt 1 and moving cone liner 3, and carefully check whether there are layers, cracks, sand inclusions, pores and shrinkage defects. If there are these defects , use a grinding wheel or arc gouging to shovel out, and use a grinding wheel to grind off the hardened layer at the worn part;
[0028] (2) Use an angle grinder to incline the upper and lower connection sections ...

The invention relates to a method for welding a cutting ring of a cone crusher with a locking bolt and a movable cone liner plate. The method comprises the following steps of: cleaning mud dirt, oil dirt and rust at a welding joint of the cutting ring, the locking bolt and the movable cone liner plate, carefully checking if disadvantages such as peeling layers, cracks, sand inclusions, air holes and shrinkage cavities exist, and rubbing out a hardened layer at an abraded part by using a sand wheel; obliquely arranging an upper opening and a lower opening at upper and lower connecting fault surfaces of the cutting ring by using an angle grinder; selecting a welding rod and a welding machine, wherein the welding rod is selected from A172 stainless steel welding rods with the diameters of 3.2 and 4.0; the welding machine is an AC (Alternating Current) electric welding machine; and a multi-layer welding way is adopted. According to the invention, the A172 stainless welding rod and suitable temperature control conditions are selected, so that martensite and hot crack are prevented efficiently; and efficient welding among different materials is not only realized, but requirements on the mechanical property of the welding joint are also satisfied.
Description
technical field [0001] The invention relates to a welding method for a cutting ring of a cone crusher, a locking bolt and a moving cone liner. Background technique [0002] Under normal circumstances, when the cone crusher works continuously for 250-300 hours, it is necessary to disassemble and replace the moving cone and fixed cone liner. The locking bolt of the cone crusher plays the role of fixing the cutting ring and the moving cone liner. Because the tightening direction of the locking bolt is consistent with the rotating direction of the moving cone when the moving cone is idling, the cone crusher is affected by friction when crushing stones. The tightening direction of the locking bolt is opposite to the rotating direction of the moving cone, and the locking bolt cannot fix the moving cone liner at this time. At the same time, when the cone crusher is working, the movable cone liner will expand, which will generate greater stress or tension on the locking bolts, resu...
