A stamping die for arc-shaped sheet metal workpieces

Abstract

The invention belongs to the technical field of mold stamping equipment, and particularly relates to an arc-shaped metal plate workpiece stamping die. The arc-shaped metal plate workpiece stamping diecomprises a conveying device, an upper module and a lower module. One side of the front side of a driving shaft of the conveying device is provided with a transmission wheel, one side of the front face of the transmission wheel is provided with an eccentric shaft, the upper module comprises a fixed plate, a first hydraulic rod, an upper mold base and an upper male die, one end of the upper portion of the first hydraulic rod is fixedly connected with the fixed plate, and the other end is fixedly connected with the upper mold base; a sliding groove is transversely formed in the position of thefront side of the upper mold base, a pull rod is arranged between the eccentric shaft and the sliding groove, the end, located at the eccentric shaft, of the pull rod is rotatably connected to the eccentric shaft, and the end, located at the sliding groove, of the pull rod is in sliding connection with the sliding groove; and the lower module comprises a lower female die, a support rod and a second hydraulic rod, a through groove is formed in the bottom position of an inner cavity of the lower female mold, automatic placement is achieved to avoid burning, water stains and dust of stamped plates are removed in time, and the aim of realizing automatic demoulding to reduce production cost is achieved.

Description

technical field [0001] The invention belongs to the technical field of die stamping equipment, in particular to a stamping die for arc-shaped sheet metal workpieces. Background technique [0002] Hot stamping forming technology uses the principle of metal thermoplastic forming, which can realize quenching heat treatment of sheet metal while forming, improve the forming performance of materials, and greatly expand the application range of high-strength ultra-high-strength steel in auto parts. [0003] Parts using the cold stamping process have a relatively large degree of freedom in shape design, and can form parts of the required shape and size through 3-5 processes. In principle, steel plate hot stamping can only be formed by one stamping process, so the shape design of parts should fully consider its process characteristics. For middle-channel parts with deep stamping depth and difficult forming, cold stamping can be used for pre-forming, and then hot stamping, but equipm...

Problems solved by technology

[0006] In order to make up for the deficiencies of the existing technology and solve the problem that the raw materials in the stamping process are easily burnt when they are placed inside the mold through the transfer device, and the use of a mechanical arm greatly increases the production cost; the invention proposes an arc-shaped sheet metal workpiece stamping die
