[0004] The purpose of this invention is to provide an automatic loading and unloading fixture for punch presses, which solves the problems of low work efficiency and safety risks associated with manual loading and unloading in stamping production.

[0005] To achieve the above objectives, this utility model employs an automatic punch press loading and unloading fixture, comprising an upper die, a lower die, a feed groove, an discharge groove, a connecting plate, a drive plate, a guide plate, a guide wheel, and a tension unit. The feed groove is fixedly connected to the lower die and located above it. The discharge groove is fixedly connected to the lower die and located below it. The connecting plate has a connecting groove and is slidably connected to the feed groove, with the feed groove and discharge groove respectively adapted to the connecting groove. The drive plate is fixedly connected to both the connecting plate and the guide plate. The guide plate is respectively disposed on the outer side of the upper die and the lower die, and has a guide groove. The guide wheel is fixedly connected to the upper die and slidably disposed within the guide groove. The tension unit is connected to both the lower die and the guide plate.

[0006] The tension unit includes a tension spring and a connecting column. The connecting column is fixedly connected to the guide plate and is located on the outer side wall of the guide plate. One end of the tension spring is connected to the connecting column.

[0007] The automatic loading and unloading fixture for the punch press also includes a limiting module, which is located on the outer side wall of the lower die.

[0008] The limiting module includes a limiting protrusion and a limiting post. The guide plate has a limiting groove. The limiting protrusion is fixedly connected to the lower pressing mold and is located on the outer side wall of the lower pressing mold. The limiting post is fixedly connected to the limiting protrusion and is slidably disposed in the limiting groove.

[0009] The automatic loading and unloading fixture for the punch press also includes a base, which is fixedly connected to the lower die and located below the lower die.

[0010] This utility model discloses an automatic loading and unloading fixture for a punch press. The upper die is installed on the punch press, and the lower die is fixed to the machine base, connected to the guide plate and the tension unit. After connection, a simulation is performed to ensure smooth operation without jamming before starting work. The punched products are placed into the feed chute, with a capacity of 200 pieces at a time, and products can be continuously added without stopping the machine. During unloading, the connecting groove first connects to the feed chute, and the product falls from the feed chute into the connecting groove, driving the upper die to move downwards. The guide wheel on the mold moves within the guide groove. Simultaneously, under the action of the tension unit, the guide plate moves away from the drive plate. The guide plate drives the drive plate to move, and also drives the connecting plate to move. The product moves within the connecting groove until the connecting groove connects with the discharge groove, and the product falls from the discharge groove, realizing the discharge operation. The upper die is driven to move upward, so that the connecting groove connects with the feed groove for feeding operation. The above steps are repeated to improve production efficiency, reduce the labor intensity of operators, and reduce operational risks. Attached Figure Description
