Description

Technical Field

[0001] This utility model relates to the field of forming equipment technology, specifically to a stabilizer bar indenter processing device. Background Technology

[0002] Stabilizer bars are crucial components of automotive suspension systems. Their connecting ends, commonly referred to as indenters, require bending and stamping to ensure connection strength and assembly accuracy. Current manufacturing processes typically employ multiple steps and equipment to process stabilizer bar indenters. For example, the connecting end is first pre-bent on a bending machine, and then the workpiece is transferred to a stamping press for final stamping using a different set of dies.

[0003] This step-by-step processing flow has a significant problem: the workpiece needs to be repositioned and clamped during process transitions. Multiple positioning inevitably leads to cumulative errors, making it difficult to guarantee the dimensional accuracy and consistency of the final product. When the machining accuracy is substandard, it not only causes assembly difficulties but may also lead to stress concentration in the stabilizer bar during use, affecting its fatigue life and overall vehicle safety. Furthermore, the multiple transfers and repositioning of the workpiece significantly reduce production efficiency and increase labor costs. Therefore, how to achieve high-precision bending and forming of the stabilizer bar indenter within a single processing cycle is a pressing technical problem that needs to be solved in this field. Summary of the Invention

[0004] This utility model provides a stabilizer bar indenter processing device, the purpose of which is to solve the technical problem that the mold cannot complete the bending and forming of the stabilizer bar indenter with high precision in a single process flow in the prior art.

[0005] This utility model provides a stabilizer bar indenter processing device, comprising: A vertical machine tool is provided with a worktable for fixing a fixed mold base and a support platform for fixing a moving mold base. The support platform is driven by a hydraulic device and reciprocates relative to the worktable in a vertical direction. First guide posts are fixedly connected to the four corners of the worktable, and first guide sleeves are fixedly connected to the four corners of the support platform.

A movable mold base is fixedly connected to the lower surface of the support platform and moves with the support platform. The movable mold base includes a first movable mold core that cooperates with the first fixed mold core and a second movable mold core that cooperates with the second fixed mold core. When the hydraulic device drives the support platform to move toward the worktable, the first fixed mold core and the first moving mold core close together to bend the connecting end of the stabilizer rod. At the same time, the second fixed mold core and the second moving mold core close together to stamp the connecting end, so that bending and stamping are completed within one processing stroke.

[0006] Furthermore, at least one second guide sleeve is fixedly connected to the fixed mold base, and at least one second guide post is fixedly connected to the moving mold base, with the second guide post slidingly engaging with the corresponding second guide sleeve.
