[0001] The utility model belongs to the technical field of stamping dies, and in particular relates to a stamping die for a slide rail frame support plate of an automobile seat. Background Art
[0002] With the rapid development of the automobile manufacturing industry, the quality requirements for auto parts are getting higher and higher, and brand competition is becoming more and more fierce. Details often determine success or failure, so the requirements of OEMs for parts are paying more and more attention to details, such as comfort level, appearance aesthetics, etc.
[0003] A super high strength automobile seat slide frame support plate stamping die with authorization announcement number CN 217191915 U includes a fixed box, a base is installed on the top of the fixed box, a die is installed on the top of the base, two support plates are installed on the top of the base, a fixed plate is fixedly installed on the top of the support plate, a hydraulic cylinder is installed on the top of the fixed plate, a punch is installed on the output shaft of the hydraulic cylinder, two L rods are installed on the punch, a protective shell is slidably installed on the two support plates, a guide assembly is provided between the protective shell and the support plate, a pushing mechanism is provided between the L rod and the protective shell, a sliding hole is opened on the top of the base, a sliding rod is slidably installed in the sliding hole, the top of the sliding rod extends into the die and is installed with a push plate. The utility model has a reasonable design, and can protect the stamping process by providing a protective shell, improve the safety of stamping, and facilitate the stamping parts to be pushed out of the die by providing a push plate.
[0004] Although the above application can protect the stamping process and improve the safety of stamping by setting a protective shell, it is unreliable to lift the stamped parts only by the elastic force of the spring after the stamping is completed, because the stamped parts themselves have weight. If the stamped parts are stuck tightly in the forming cavity, it is difficult to lift them up by the elastic force of the spring. The lifting effect is not fully considered and cannot be linked with the protective structure. For this reason, we proposed a stamping die for a car seat slide rail frame tray. Utility Model Content
