Problems solved by technology
Since machining is carried out after isothermal quenching, the material hardness is HBS350 during machining, and mechanical cutting such as milling is very difficult. The processing time of parts is long, the manufacturing cost is high, and the tool is easy to break when drilling, and the manufacturing cycle of parts is long.

Embodiment
[0023] Example: see figure 1 with figure 2 , in the figure, 1-positioning seat, 2-bolt, 3-automobile leaf spring seat.
[0024] The process manufacturing method of ADI material automobile leaf spring seat, its technical scheme is:
[0025] a. First cast the blank, and then carry out mechanical rough machining;
[0026] B, make anti-deformation device secondly, anti-deformation device comprises positioning seat 1, is provided with through hole on positioning seat 1, and the size and the position of through hole are identical with the installation hole on the automobile leaf spring seat 3;
[0027] c. Before the isothermal quenching, screw the bolt 2 through the through hole and the mounting hole, so that the positioning seat 1 and the automobile leaf spring seat 3 are tightly assembled together, and then the positioning seat 1 and the automobile leaf spring seat 3 are subjected to isothermal In the quenching process, after the isothermal quenching is completed, it is first ...

The invention discloses a manufacturing method of an ADI-material automobile steel leaf spring seat. The manufacturing method includes: casting a blank, and performing rough machining; manufacturing an anti-deformation device which comprises a positioning seat, wherein the positioning seat is provided with a through hole, and the size and position of the through hole are identical with those of the mounting hole in the automobile steel leaf spring seat; allowing a bolt to penetrate the through hole and be connected with the mounting hole in a threaded manner before isothermal quenching so as to allow the positioning seat to be tightly assembled to the automobile steel leaf spring seat, subjecting the positioning seat and the automobile steel leaf spring seat to the isothermal quenching, then cooling to room temperature, removing the bolt, taking out the automobile steel leaf spring seat, and performing fine machining to obtain the ADI-material automobile steel leaf spring seat. The manufacturing method has the advantages that the machining difficulty of ADI-material parts is lowered, part machining time is shortened effectively, the manufacturing cost of the automobile steel leaf spring seat is lowered, the deformation problem in the isothermal quenching process of the automobile steel leaf spring seat is solved effectively at the same time, and clients' product quality requirements are satisfied.
Description
[0001] Technical field: [0002] The invention relates to a processing method of an automobile leaf spring seat, in particular to a manufacturing method of an ADI material automobile leaf spring seat. [0003] Background technique: [0004] At present, the leaf spring seat parts of high-end heavy-duty trucks start to use ADI materials. The material strength is 1050Mpa, the elongation is 6%, and the hardness is HBS350. The traditional production process route is casting blank - austempering - mechanical processing. Since machining is carried out after isothermal quenching, the material hardness is HBS350 during machining, and mechanical cutting such as milling is very difficult. The processing time of parts is long, the manufacturing cost is high, and the tool is easy to break when drilling, and the manufacturing cycle of parts is long. In addition, during the isothermal quenching process, the deformation of the automobile leaf spring seat is generally caused. After measuring a...
