Abstract

The invention discloses an automatic mechanical material return device and a material return method, comprising a support platform, a lower die, and a control box. Support legs are arranged at the lower four corners of the support platform, and the lower die is arranged on the support platform. , the bottom of the lower die is provided with a bottom plate, the top of the bottom plate is provided with a material return hole, the bottom of the bottom plate is provided with a liquid channel, the bottom of the lower die is provided with a pipe joint, and the bottom of the support table is provided with a foot Pedal, a return spring is arranged under the foot pedal, a support plate is arranged under the return spring, and a push switch is arranged above the support plate. The beneficial effect is that the present invention uses hydraulic oil to directly lift the material in the lower die to exit the lower die, simplifies the structure, and improves the convenience of maintenance. At the same time, the oil inlet and oil return are completed by a unified pipeline by using a bidirectional hydraulic pump, ensuring The oil return speed of the returned material is improved, and the hydraulic oil is applied to the lower die and the surface of the material to form an oil film, which prevents the surface from rusting and prolongs the service life.

Description

Technical field [0001] The invention relates to the field of material returning devices, in particular to an automatic mechanical material returning device and a material returning method. Background technique [0002] Stamping is a forming method that relies on presses and dies to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, so as to obtain workpieces (stamping parts) of desired shape and size. Stamping and forging are both plastic processing (or pressure processing), collectively known as forging. The blanks to be stamped are mainly hot-rolled and cold-rolled steel plates and strips. After the stamping is completed, the material needs to be returned to remove the material from the mold. [0003] Compared with the Chinese patent with application number 201310189814.X, an automated mechanical unloading device is disclosed. A connecting plate is provided on the top of the worktable, and the connecting plate is connected wit...
