Novel punching machine for hinge punching

Abstract

The invention relates to a novel punching machine for hinge punching. The novel punching machine can effectively position hinge metal plates, precisely finish the punching work process, can automatically finish the works of feeding and discharging and is high in working efficiency. The novel punching comprises a workbench, a punching head, a feed mechanism, a base table and a die. A die working hole is formed in the workbench, and the base table is arranged below the workbench. The feed mechanism comprises a first hydraulic oil cylinder and a push plate arranged at the output end of the first hydraulic oil cylinder. A working groove sinking inwards is formed in the top of the die. An inclined face is arranged between the bottom face of the working groove and the top face of the die. A through hole and a plurality of guide holes are formed in the position, located in the working groove, of the die. Second guide holes are formed in the base table. A second hydraulic oil cylinder, a connection plate and a plurality of guide rods are arranged at the bottom of the base table. The connection plate is fixed to the output end of the second hydraulic oil cylinder. The guide rods are vertically fixed to the top face of the connection plate. The guide rods move in the second guide holes and the first guide holes relatively.

Description

technical field [0001] The invention relates to a hinge processing and production equipment, in particular to a novel hinge punching machine. Background technique [0002] As we all know, the basic principle of the punching machine is to drive the flywheel through the motor, and drive the crank linkage mechanism through the clutch transmission gear to make the punch move up and down, and punch the metal plate. The punching machine is usually double-action. There are two sliders, which are divided into inner slider and outer slider. The inner slider drives the punch, and the outer slider drives the blank holder. During the punching operation, the blank holder first moves to press the edge of the metal plate, and the inner slider then moves to proceed. Punching, due to its good metal punching performance, is widely used in the punching of hinges; the punching machine of the prior art usually includes a horizontally arranged workbench and a punch arranged above the workbench. ...

[0002] As we all know, the basic principle of the punching machine is to drive the flywheel through the motor, and drive the crank linkage mechanism through the clutch transmission gear to make the punch move up and down, and punch the metal plate. The punching machine is usually double-action. There are two sliders, which are divided into inner slider and outer slider. The inner slider drives the punch, and the outer slider drives the blank holder. During the punching operation, the blank holder first moves to press the edge of the metal plate, and the inner slider then moves to proceed. Punching, due to its good metal punching performance, is widely used in the punching of hinges; the punching machine of the prior art usually includes a horizontally arranged workbench and a punch arranged above the workbench. Move vertically and horizontally, punch the hinge metal plate on the workbench, and then complete the punching of the metal plate; however, the size of the hinge metal plate is usually small, and the blankholders of the punching machine in the prior art are usually difficult to align The hinge metal plate is positioned and pressed, so that the position of the through hole on the hinge metal plate is often inaccurate. At the same time, the punching machine of the prior art is difficult to realize the automatic loading and unloading process, and the work efficiency is low.
