Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a quick-change structure for cutting PINs in stamping dies. Background Technology

[0002] Stamping dies are used to stamp terminal products. There are two types of terminal products involved. One type of terminal product requires the pins to be cut, while the other type does not. The common method is to first use stamping dies to uniformly produce terminal product strips with pins. Then, according to actual needs, the terminal product strips are transported to a special pin cutting machine. The strips need to be repositioned, fed, and then cut. This operation is cumbersome, and the additional pin cutting machine occupies space and has high cutting costs.

[0003] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a quick-change structure for cutting the pins of stamping dies. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a quick-change structure for cutting pins in stamping dies. The quick-change component can quickly switch the extended or retracted state of the pin cutting punch to meet the different cutting working states of stamping dies and has wide applicability.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a quick-change structure for cutting PINs in a stamping die is provided. This quick-change structure includes a lower stamping die, an upper stamping die, a PIN cutting punch, a quick-change assembly, and a lower cutting die. The upper stamping die is connected above the lower stamping die. The lower and upper stamping dies are provided with a multi-station punch module for continuously stamping and forming terminal product strips on their opposite surfaces. The upper stamping die is equipped with a PIN cutting punch that can extend or retract according to actual cutting requirements. The PIN cutting punch is driven to extend or retract by the quick-change assembly. The lower stamping die is equipped with a lower cutting die that cooperates with the PIN cutting punch. The lower stamping die is also provided with a discharge port opposite to the PIN cutting punch for discharging the cut-off PINs.

[0006] Preferably, the quick-change assembly includes a baffle, a spring, a side slider, and a side pressure plate. The baffle is installed at the bottom of the upper clamping plate of the stamping die. The pin cutting punch is movably inserted into the upper clamping plate. The upper part of the pin cutting punch has a mounting part extending horizontally outward. The mounting part is vertically opposite to the baffle. A spring that abuts against the baffle is installed in the spring mounting hole on the bottom surface of the mounting part. The side slider is horizontally slidably installed on the upper die base of the stamping die. The side slider and the pin cutting punch have a matching guide slope on their opposite surfaces. A side pressure plate for limiting the position of the side slider is installed at the outer end of the upper die base. The side slider has an outer end face that mates with the side pressure plate and a U-shaped groove. The lower end of the side pressure plate can be inserted into the U-shaped groove. The state of the pin cutting punch is changed by switching the mating surfaces of the side slider and the side pressure plate.

[0007] Preferably, the quick-change assembly also includes fixing screws, and the side pressure plate can be quickly locked onto the upper mold base by fixing screws.
