Automatic feeding and discharging punching die for automobile parts

Abstract

The invention discloses an automatic feeding and discharging punching die for automobile parts. The automatic feeding and discharging punching die comprises a base, wherein a backing ring is mounted on the upper surface of the base, a punching die disc is rotatably mounted on the backing ring, a plurality of material grooves are symmetrically formed in the upper surface of the punching die disc, and a punching hole channel is formed in the groove bottom of each material groove; and a control hole is formed in the center of the punching die disc, a control hydraulic cavity is formed in the center of the base, a hydraulic rod is inserted into the control hydraulic cavity in a sliding mode, the upper end of the hydraulic rod does not penetrate through the control hole in a contact mode, extends to the position above the punching die disc and is provided with a cross arm, and a punching drill is mounted on the lower surface of the cross arm. The punching die disc intermittently rotates and a discharging rod vertically moves through vertical movement of the hydraulic rod, so that the material grooves can cooperate with material barrels to achieve automatic feeding, a discharging rod can cooperate with the punching hole channel and the material grooves to achieve automatic discharging, extra equipment does not need to be added, the production efficiency is improved, more energy is saved, and the cost is lower.

Description

technical field [0001] The invention relates to the field of molds for auto parts, in particular to a punching die for automatic feeding and discharging of auto parts. Background technique [0002] Auto parts include many connectors, and the connections between the connectors are usually locked by screws or bolts. Therefore, it is necessary to punch holes on the connectors to facilitate the installation of screws and bolts. [0003] Existing punching dies are usually fixed dies that are punched successively by a hydraulic punching machine, and the punching speed is low, while continuous punching with chain belt conveyance requires additional transportation equipment, which increases both cost and energy consumption. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings of the prior art, such as the low efficiency of successive punching of fixed dies, the need to increase the cost of transportation equipment and high energy con...
