Abstract

The invention belongs to the field of plate spring preparation, and in particular relates to an influx type quenching process, that is, the plate spring is placed in an empty quenching tank, and the plate spring is hot-pressed with a quenching fixture, and then the quenching medium is rapidly injected from the upper part. pouring into the quenching tank, on the one hand, by using a large amount of low-temperature, continuously pouring, and fast-flowing quenching medium, the metallographic structure of the obtained leaf reed after quenching is made uniform, and the grains are made finer, so that the structure is formed from The transformation from austenite to martensite is faster and more complete, which prolongs the fatigue life of the leaf spring. On the other hand, it improves the quenching speed and production efficiency, and shortens the product production cycle. The present invention also provides a quenching equipment used in the quenching process, which has a compact structure, saves space, replaces manual operation, and realizes mechanized production, which not only saves manpower, avoids potential safety hazards, but also ensures quenching efficiency , so as to meet the needs of industrial production.

Description

Technical field

[0001] The invention relates to an inrush quenching process and quenching equipment, and belongs to the field of leaf spring preparation. Background technique

[0002] Traditional automobile leaf springs are composed of several pieces of spring steel. In the production process of automobile leaf springs, the processing technology of the leaf springs is very important. Existing leaf spring sheet quenching production lines are mostly row-type production lines, multiple quenching machines are arranged in a straight line, and the quenching medium tank is located at the bottom of the quenching machine. After the leaf spring comes out of the quenching furnace, it is conveyed to the front end of each quenching machine through the conveying mechanism. The worker completes the manual feeding work, starts the clamping mechanism of the quenching machine, clamps the leaf spring and quickly puts it into the quenching medium. The cooling process of the workpiece quenching is c...

Embodiment Construction

[0034] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0035] Such as figure 1 , 2 As shown, the quenching equipment of the present invention includes a quenching furnace, a manipulator 5, a quenching tank 1, a quenching fixture 3, a fume purification treatment system 16 and a quenching medium cooling system 8. The quenching fixture 3 is installed in the quenching tank 1, and each group of quenching The clamp 3 is composed of two clamps 13, one of which is connected to the displacement drive mechanism. The two clamps 13 of the quenching clamp 3 can form a space that matches the shape of the leaf spring 14. When the two clamps 13 are matched, the The leaf spring 14 is clamped and positioned and formed by hot pressing; a quenching box cover 4 is installed on the top of the quenching tank 1 to close the quenching tank 1; the side wall of the quenching tank 1 is provided with a quenching medium inlet, an air inl...
