Description
Technical Field
[0001] The utility model relates to the field of pressing devices, in particular to a compressor connecting rod pressing device. Background Art
[0002] The compressor connecting rod is a key transmission component in the compressor. Its function is to transmit the thrust on the piston to the crankshaft, and at the same time convert the rotational motion of the crankshaft into the reciprocating motion of the piston, thereby driving the working cycle of the compressor; the connecting rod works closely with the piston and crankshaft and is an indispensable part of the normal operation of the compressor.
[0003] The processing flow of compressor connecting rods usually includes the following steps: material selection, blank preparation, rough machining, heat treatment, pressing, finishing, surface treatment, and testing; pressing treatment is one of the important steps in connecting rod processing. During the pressing and forming process, the material undergoes plastic deformation and its internal structure is optimized, which helps to improve the mechanical properties and fatigue resistance of the connecting rod.
[0004] Existing compressor connecting rods are usually pressed together by extruding the forgings with the help of a die. During production and observation, it was found that after the forgings are pressed together, the surface will adhere to the lower die, which will make the forging disassembly operation more cumbersome and increase the working time required for forging disassembly.

At this time, the air pipe 4 can be connected to an air pump so that the air pump will extract air from the air pipe 4, and the air around the air hole 42 will enter the top plate 18 through the air hole 42, so that a negative pressure state is formed at the air hole 42. At this time, the debris generated when the forgings on the surface of the workbench 15 are pressed will enter the top plate 18 under the action of suction, which improves the convenience of the device for cleaning the workbench 15 and reduces the impact of the debris on the surface of the workbench 15 on the pressing of subsequent forgings. At the same time, the air flow will also speed up the air flow speed around the forgings, so that the surface of the forgings can be cooled quickly; after the previous forging is pressed, the air hole 42 will clear the debris on the surface of the workbench 15, and then the next forging can be placed The top plate 18 is squeezed, and the top plate 18 moves into the first slide groove 19 and moves with the elastic sheet 5.
