Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automation assembly, specifically to a stamping automatic feeding device for hinge production. BACKGROUND

[0002] Hinge is a commonly used connecting component on furniture at present, and its production efficiency is accelerated and processing quality is improved, which has become a problem faced by the majority of hinge manufacturers. Chinese patent document CN110541639A discloses a two-stage force hinge with adjustable damping, wherein the hinge arm and the hinge cup are core components in the hinge. The hinge arm and the hinge cup are generally manufactured by continuous stamping forming processing mode, in order to reduce the forming process of the components, the manufacturer will use automatic stamping continuous processing die for processing.

[0003] Chinese patent document CN202192789U discloses a full-automatic stamping mechanical hand, which drives the up and down and left and right movement of the mechanical arm by using a servo motor and a belt transmission mechanism, and the workpiece is grabbed by a vacuum suction nozzle to realize automatic feeding and discharging of the parts during stamping. Chinese patent document CN111545663A discloses a hardware stamping mechanical hand, which drives the movement of the sliding block by using the combination of the motor and the screw rod, and drives the unfolding arm with the suction cup by the cylinder to realize automatic feeding and discharging of the parts during stamping. Although the mechanical hands disclosed in the above two patent documents can realize the grabbing and placing of the parts during stamping, they still have major technical defects. Firstly, during the operation of the punch, the pressure and instantaneous impact force during stamping are very large, and the mold and its surrounding area will produce strong vibration. Therefore, whether it is belt transmission or screw rod transmission, under the strong vibration, the belt transmission will be loose or the screw rod will be deformed after bearing the impact force, which greatly affects the service life. Secondly, in the continuous processing die, the stability of the workpiece during continuous stamping is required to be very high, and due to the influence of the pressure and instantaneous impact force during stamping, the grabbing of the workpiece by the suction cup or the vacuum suction nozzle is extremely easy to fall off due to vibration, which not only seriously affects the normal processing of continuous stamping, but also causes damage to the mold.
