Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a die for hydraulic metal stamping parts. Background Art

[0002] Stamping dies refer to dies used in the metal stamping process. Such dies are usually made of high-strength steel and can withstand the pressure and impact during high-speed stamping. The design and manufacture of stamping dies are crucial for producing stamping parts that meet the requirements of dimensional accuracy and surface quality. Common stamping dies include punching dies, drawing dies, bending dies, shearing dies, etc.

[0003] Common stamping dies cannot perform continuous fixed-distance stamping. At the same time, for some dies with continuous stamping, one-time loading is limited and timed loading is required, which reduces production efficiency. Based on these problems, Chinese patent CN216679744U discloses a continuous stamping die for metal stamping. By setting a stamping table, active transmission roller, driven transmission roller and stepper motor, the device can stamp the selected metal stamping part length at one time through continuous stamping, thereby greatly improving the stamping efficiency of metal stamping parts.

[0004] When the device uses the active transmission roller and the driven transmission roller to transport the metal stamping parts at a fixed distance, the metal stamping parts are in an unfixed state, and the driven transmission roller lifts up one end of the bottom of the metal stamping parts. Therefore, the metal stamping parts will slide during the stamping process, which not only affects the quality of the stamped finished product, but also hinders the normal progress of the stamping work.
