Description

Technical Field

[0001] This utility model relates to the field of solenoid valve assembly technology, and in particular to a riveting assembly for solenoid valve assembly. Background Technology

[0002] As a key actuator in the field of fluid control, solenoid valves are widely used in industrial applications such as hydraulics, pneumatics, and water treatment. Their assembly quality directly determines the accuracy of fluid flow control, sealing performance, and service life. The precise assembly of the valve core and seat is a core assembly process. The valve core must be coaxially embedded into the pre-set mounting chamber inside the valve seat to ensure that after subsequent assembly with the coil, the valve core can reciprocate stably along the valve seat axis, thereby achieving reliable fluid flow control. Therefore, the connection strength and coaxiality between the valve core and seat are key indicators affecting the performance of solenoid valves. In the mass production line of solenoid valves, after the valve core and valve seat are pre-assembled (the valve core is embedded in the valve seat cavity), a riveting process is required to fix them together to prevent relative displacement during subsequent operation. To ensure connection strength, existing riveting processes typically employ high-pressure riveting, where an axial pressure of 30-200kN is applied by the punch of a riveting machine, causing plastic deformation of the metal material at the valve seat port to form a ring-shaped locking structure, thus axially limiting and fixing the valve core. However, there is an irreconcilable contradiction between the aforementioned high-pressure riveting requirements and the automated conveying of the production line. To avoid the risks of conveyor line damage and insufficient riveting accuracy, the existing solutions in the industry generally involve manually removing the pre-assembled valve core-seat assembly from the conveyor line and transporting it to a separate riveting station; manually operating the positioning fixture to clamp and fix the assembly, and starting the riveting machine to complete the riveting; after riveting, the finished product is then manually transported back to the conveyor line and transferred to the next process.

[0003] In the riveting process of solenoid valve core and seat, the "risk of damage to the conveyor line by high-pressure riveting" and the "low efficiency and low precision of manual riveting" have created a technical contradiction, making it difficult for mass production lines to achieve automated integration of the riveting process. This has become a key bottleneck restricting the assembly efficiency and quality stability of solenoid valves, and there is an urgent need for a technical solution that can adapt to high-pressure riveting and can work in conjunction with automated conveyor lines.
