Punching machine and method for automatically taking and conveying punched workpiece

Abstract

The embodiment of the invention discloses a punching machine which comprises a rack, a feed mechanism, a discharge mechanism, a conveying mechanism, a locating mechanism and a punching mechanism, wherein the feed mechanism, the discharge mechanism, the locating mechanism and the punching mechanism are installed on the rack, the feed mechanism comprises a feed conveyer belt installed at one end of the rack, the discharge mechanism comprises a discharge conveyer belt installed at the other end of the rack, the locating mechanism comprises a workpiece pre-locating plate installed on the feed conveyer belt, the punching mechanism comprises a workpiece punching die and a punching device for punching a workpiece on the workpiece punching die, the workpiece punching die is located between the feed conveyer belt and the discharge conveyer belt, the conveying mechanism comprises a material taking slide plate and a drive device for driving the material taking slide plate to move among the feed conveyer belt, the workpiece punching die and the discharge conveyer belt, and a first vacuum slot and a second vacuum slot are installed at the two ends of the material taking slide plate. Due to the punching machine provided by the invention, the punched workpiece can be precisely located and does not deviate from the position in the conveying process. The invention further discloses a method for automatically taking and conveying the punched workpiece.

Description

technical field [0001] The invention relates to a stamping machine, in particular to a stamping machine for automatically feeding and retrieving materials. The invention also relates to a method for automatically feeding and taking out stamping workpieces. Background technique [0002] Presses are common production equipment used to mass-produce mechanical structures or components. A stamping machine uses a die or blade to process a sheet of material, deforming or breaking it to form the desired shape. The stamping machine can obtain parts with complex shapes by one stamping process, which simplifies the manufacturing process and reduces labor costs. [0003] The punching machine is mainly composed of a feeding and discharging mechanism, a transmission mechanism, and a stamping mechanism. The feeding and discharging mechanism is used for feeding and returning materials. The workpiece is sent to the discharge mechanism, but the existing transmission mechanism is mainly ope...

Problems solved by technology

[0003] The punching machine is mainly composed of a feeding and discharging mechanism, a transmission mechanism, and a stamping mechanism. The feeding and discharging mechanism is used for feeding and returning materials. The workpiece is sent to the discharge mechanism, but the existing transmission mechanism is mainly operated by manual or simple manipulator, and the simple manipulator pushes and slides the workpiece to be stamped into the stamping die of the stamping mechanism, and the stamping head of the stamping mechanism For stamping, with such a transfer mechanism of the manipulator, the transmission accuracy of the workpiece to be punched cannot be guaranteed. Even if the workpiece pre-positioning plate is set in the feeding structure, when the manipulator pushes the workpiece to be punched from the feeding mechanism into the stamping mechanism, There will also be deviations in the position. The defects of this transmission structure will lead to deviations in the shape accuracy of stamped products, and the specifications cannot be guaranteed to be consistent.
