Description

Technical Field

[0001] This utility model relates to the technical field of piston ring production equipment, specifically a piston ring shaping and mounting equipment. Background Technology

[0002] Piston ring manufacturing requires high-temperature treatment. Specifically, the heat treatment process for piston rings includes tempering and annealing. During tempering, the piston rings are heated at 860–900°C and then rapidly cooled to obtain a martensitic structure with a hardness of 58–60 HRC. During annealing, the piston rings are tempered at 500–600°C, causing the cementite to decompose and precipitate graphite, resulting in tempered sorbite and spheroidal graphite, which have high strength and toughness, with a hardness of 100–110 HRB.

[0003] Before high-temperature treatment, piston rings need to be stacked in a shaping mold to shape the outer ring of the piston rings, making it easier to enter the next high-temperature treatment process. However, in the existing technology, the piston rings are installed manually, which is inefficient, time-consuming and labor-intensive. Utility Model Content

The empty shaping tire 37 is placed at the shaping tire input station 23 of the shaping tire support plate 3 by the robot arm. The linear drive module drives the shaping tire 37 on the shaping tire support plate 3 to move to the piston ring tire mounting station 5.

[0034] 2) The first drive motor 34 of the lower clamping mechanism 7 drives the lead screw 33 to rotate, which in turn drives the positioning jaws 36 to clamp the shaping tire 37, as detailed below. Figure 3 As shown.

[0037] 5) The lifting drive 10 drives the upper clamping mechanism 6 to move upward and disengage from the piston ring transfer platform 11, and the second linear drive 16 drives the piston ring transfer platform 11 to move backward and disengage from the support of the stacked piston rings.

The screw jack 20 drives the pressing plate 18 to press the stacked pistons into the shaping tire 37. Then, the pressing plate 18 is driven to return to its original position upwards. At the same time, the lifting driver 10 drives the upper clamping mechanism 6 to return to its original position upwards.

[0039] 7) The first drive motor 34 of the lower clamping mechanism 7 drives the lead screw 33 to rotate, thereby causing the positioning gripper 36 to release the shaping tire 37.

[0040] 8) The linear drive module drives the shaping tire 37 on the shaping tire support plate 3 to the shaping tire inlet / outlet station 4. The first linear drive 29 drives the shaping tire 37 equipped with piston rings to move to the shaping tire outlet station 24.
