Description

Technical Field

[0001] The utility model relates to the field related to the processing of fuse lead caps, and in particular to an automatic forming device for fuse lead caps. Background Art

[0002] During the processing of fuses and lead caps, lead caps need to be installed at both ends of the fuse to ensure the stability and safety of the electrical connection. By extrusion, the lead caps can be tightly fixed to the ends of the fuse to prevent poor contact or short circuit problems caused by looseness or vibration, improve the efficiency of current transmission, and enhance the reliability and durability of the fuse in the circuit, thereby effectively protecting the circuit from damage caused by excessive current and ensuring the safe and stable operation of the entire electrical system.

[0003] The existing technology usually requires manual operation when processing and installing fuses and lead caps. This includes accurately placing the lead caps on both ends of the fuse and squeezing them using specific tools or techniques to ensure a tight connection between them. Although manual operation can meet processing requirements to a certain extent, it often has limitations such as low efficiency, high cost, and processing quality affected by human factors.

[0004] In addition, when processing and installing the fuse tube and lead cap, especially when squeezing the lead cap, a certain amount of force needs to be applied to ensure the tightness of the connection, which increases the risk of damage to the fuse tube. The glass fuse tube is relatively fragile and can be easily squeezed by external force, causing cracks, breakage and other problems. This will not only destroy the integrity of the fuse tube, but also affect its normal electrical performance and safety protection function.

[0005] Therefore, we make improvements to this and propose an automatic forming device for fuse lead caps. Utility Model Content

[0008] The invention provides an automatic forming device for fuse lead cap to solve the above problems.

[0009] The specific application is as follows:

[0010] The utility model comprises a base, wherein a sliding groove is provided on the upper surface of the base, and a guide rail is fixedly installed inside the sliding groove, and a movable plate is slidably connected to the upper side of the guide rail inside the sliding groove, an accessory placement mechanism is provided on the upper surface of the movable plate, and a push handle is fixedly installed on the upper surface of the movable plate, a fixing box is fixedly installed on the upper surface of the base, and a crimping fixing mechanism is provided inside the fixing box;

[0018] Compared with the prior art, the present invention has the following beneficial effects:
