[0002] In the field of automobile manufacturing, the rear lower control arm is a key suspension component to ensure vehicle performance. With the development of the automobile industry, the requirements for its quality and production efficiency are increasing. In this context, stamping technology has become an important means of producing automobile rear lower control arms. Early processing methods could not meet the needs of large-scale production and high precision. Stamping technology has been widely used due to its advantages of high efficiency, high precision and high material utilization. The continuous increase in automobile production has prompted the stamping process to be continuously improved and optimized in the manufacturing of automobile rear lower control arms to meet the market demand for high-quality and low-cost automotive parts.

[0003] The patent application with application number CN201510613856.0 discloses a stamping device for circular parts embedded in automobile chassis control arms, including an upper die base and a lower die base, and the lower die base is installed on a base; its characteristics are: a positioning block, a third block and a fifth block are installed on the lower die base, a first block and a second block are arranged above the third block, and a spring and a pin are arranged between the third block and the second block.

[0004] In summary, during the stamping process of the rear lower control arm of a car, residual stress will be generated inside the workpiece due to plastic deformation. These residual stresses are distributed on the surface of the workpiece and within a certain depth range inside. When the residual stress exceeds the yield strength of the material, the workpiece may deform, crack, and other problems. Moreover, during subsequent processing or use, the workpiece may warp due to the release of residual stress, thereby affecting its service life.

[0015] Compared with the prior art, the present invention provides a stamping device for a rear lower control arm of an automobile, which has the following beneficial effects: 1. The present invention provides a stamping device for a rear lower control arm of an automobile. When the rear lower control arm of an automobile is stamped, residual stress will appear inside the workpiece due to plastic deformation. These residual stresses are distributed on the surface of the workpiece and in a certain depth area inside the workpiece.

[0016] 2. The present invention sets a stamping mechanism.

When the stamping plate 201 contacts the first sliding frame 301 and causes the first sliding frame 301 to slide down to the bottom of the first fixed frame 101, the second fixed frame 202 fixedly connected on both sides of the stamping plate 201 begins to function, and the dual-axis motor 203 fixedly connected to its inner wall drives the second connecting frame 204 to flip, thereby making the second fixed block 206 contact the second connecting block 313 at the bottom of the first sliding frame 301.

[0026] The inner wall of the second connecting frame 204 is fixedly connected with a second hydraulic rod 205, and the output end of the second hydraulic rod 205 is fixedly connected with a second fixed block 206. The top outer wall of the second fixed block 206 is fixedly connected with an elastic plate 208. The second fixed block 206 is used to contact the bottom of the second connecting block 313. The second fixed block 206 contacts the second connecting block 313 through the elastic plate 208 fixedly connected to the outer wall, so that the first sliding frame 301 vibrates during the upward sliding process.

When the sliding ring 308 rotates, the third protrusion 312 fixedly connected to the inner wall connecting rod 311 will contact the fourth protrusion 316. The fourth protrusion 316 is used to make the sliding ring 308 vibrate during the rotation process after contacting the third protrusion 312. When the second sliding frame 315 slides to the same height as the sliding ring 308, the workpiece stamping operation is completed. At this time, the driving motor 309 drives the driving wheel 310 to reverse the sliding ring 308 The sliding ring 308 rotates, and the third protrusion 312 on the outer surface of the connecting rod 311 fixedly connected to the inner wall of the sliding ring 308 contacts the fourth protrusion 316 fixedly connected to the outer surface of the second sliding frame 315, causing the bottom of the first sliding frame 301 to vibrate.
