Description

Technical Field

[0001] The utility model relates to the technical field of spring static pressure, in particular to a spring static pressure tooling. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external forces and return to their original shape after the external force is removed. There are many types of springs. According to their shapes, they mainly include helical springs, scroll springs, leaf springs, special-shaped springs, etc. Spring pressure treatment refers to a process method that compresses the spring to the surface of the spring material to produce beneficial residual stress opposite to the working stress, so as to improve the spring's load-bearing capacity and stabilize its geometric dimensions.

[0003] When the spring is actually subjected to static pressure, the spring needs to be sleeved on the pressing assembly, and then the pressing assembly is placed on the machine tool and pressure is applied to the pressing assembly through the side push assembly. The spring will be compressed, and the spring will be processed after being compressed for a certain period of time. However, the pressing assembly is a splicing device during processing, and it is easy to get your hands pinched when the pressing assembly is placed in the placement position of the machine tool. It is also difficult to take out after static pressure, making it inconvenient to replace. Utility Model Content

When the guide rod 14 moves up, it can drive the rotating frame 11 to move up as a whole.

[0022] The pressing assembly 6 on the rotating frame 11 will also move up. When it moves up to a certain position, the rotating frame 11 will rotate as a whole, and the rotating frame 11 will tend to be horizontal. The pressing assembly 6 can be removed from the rotating frame 11, thereby facilitating the installation and placement of the pressing assembly 6. When the guide rod 14 moves down, the rotating frame 11 will gradually become parallel to the rack 17, and the pressing assembly 6 will move to the baffle 12 position of the rotating frame 11. As the rack 17 and the rotating frame 11 continue to move downward, the pressing assembly 6 can be parallel to the push plate 3. After the push plate 3 squeezes the pressing assembly 6, the spring can be compressed. The entire processing process does not require the pressing assembly 6 to be placed on the machine tool 1.

When the knob 5 is turned, the rotating rod 13 can rotate as a whole, and the screw 16 on the rotating rod 13 can be screwed in on the protruding seat 7. When the rotating rod 13 stops, it will not rotate due to the connection between the screw 16 and the protruding seat 7, and the rack 17 will not drive the gear 19 to rotate due to gravity, thereby ensuring that the gear 19 will not rotate easily when driving the rack 17 to move. The thickness of the gear 19 is greater than the width of the rack 17, and the gear 19 will also mesh with the rack 17 when it moves horizontally.
