Description

Technical Field

[0001] This utility model relates to the field of piston ring processing technology, specifically a heat treatment device for piston ring processing. Background Technology

[0002] Piston rings are metal rings used to fit inside the piston grooves. There are two types of piston rings: compression rings and oil rings. Compression rings are used to seal the combustible mixture in the combustion chamber, while oil rings are used to scrape off excess oil from the cylinder. Piston rings are one of the core components of an engine, and their main functions in the engine are sealing, heat transfer, oil control and lubrication, and support. Therefore, piston ring materials should have suitable strength, hardness, elasticity and fatigue resistance, as well as excellent wear resistance, heat resistance and corrosion resistance.

[0003] According to the patent application published on the Internet (authorization announcement number: CN212610827U), "This utility model discloses a heat treatment device for piston ring processing, which relates to the field of heat treatment equipment technology. It includes a machine body, a heating mechanism, a lifting mechanism, a support frame, and a reaction furnace. The support frame is fixedly installed on the top of the machine body, and the lifting mechanism is fixedly installed on one side of the machine body. By setting a hydraulic cylinder, it drives the hydraulic rod to rotate, which in turn drives the furnace cover. The piston ring is easily placed by the action of the locking column, which saves the time of placing the piston ring, improves work efficiency and productivity. At the same time, the use of the motor and the locking buckle enables the motor to drive the reaction furnace to rotate. Through the action of its built-in heat-conducting jacket and heat-conducting base plate, the piston ring is heated evenly, and the surface area of ​​the piston ring is increased, which improves the heat treatment effect of the piston ring. Moreover, the structure of the device is simple and easy to operate, reduces the operation process, reduces the operation difficulty, facilitates the use of personnel, and effectively improves the practicality of the device."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This utility model, by setting a locking post to fit the piston ring, facilitates the placement and fixation of the piston ring. Furthermore, the heat-conducting jacket effectively prevents wear between the piston rings when the motor drives its rotation. However, in actual use, because the device only uses a cooling fan for heat dissipation, the fan inlet is prone to blockage. Additionally, during the heat treatment of the piston rings, the motor-driven piston ring locking post rotation can lead to uneven rotation, affecting the uniformity of subsequent processing. Therefore, an improved heat treatment device for piston ring processing is needed to solve these problems. Utility Model Content

[0035] Example 2:

[0036] Based on Embodiment 1, the existing technology uses a motor to drive the piston ring retainer, which easily leads to uneven rotation, affecting the uniformity of subsequent processing. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problem. Please refer to Embodiment 2. Figure 6 Furthermore, in conjunction with Embodiment 1, the auxiliary heat treatment mechanism 10 includes a support base 101, which is fixedly connected to the bottom of the heat treatment insulated furnace 1.

[0038] In actual operation, when this device is used, the operator first opens the protective door 3, places the piston rings to be heat-treated on the placement platform 8, then closes the protective door 3, operates the control panel 4, and works with the temperature controller 2 and the water pump inside the circulating water tank 5 to regulate the temperature inside the heat treatment insulation furnace 1. The second motor 102 operates, causing the connecting block 103 to rotate, which, in conjunction with the limit plate 104, ensures that the placement platform 8 rotates uniformly by 90° each time inside the heat treatment insulation furnace 1, thus ensuring uniform heating of the piston rings inside the placement platform 8. When the heat treatment insulation furnace 1 needs to be cooled after processing, the water pump inside the circulating water tank 5 works in conjunction with the heat treatment insulation furnace 1 to regulate the temperature inside the furnace. The cooling water channel inside the heat insulation furnace 1, in conjunction with the operation of the heat dissipation fan 7 and the heat dissipation fins, dissipates heat from the heat treatment heat insulation furnace 1. The operation of the first motor 916 causes the threaded rod 917 to rotate, which, in conjunction with the limit rod 918, causes the movable block 919 to move, thereby causing the toothed plate 9110 to move. In conjunction with the gear 914, the guide plate 913 rotates inside the connecting air duct 911, and the intake air is filtered by the filter plate 921. When the filter plate 921 needs to be cleaned, the operator pulls the sliding plate 925. The movement of the sliding plate 925, in conjunction with the spring 924, causes the locking post 926 to move, completing the limiting and disassembly between the fixed block 922 and the locking post 926.
