An internal fuse making machine

Abstract

The invention discloses an internal fuse manufacturer. The internal fuse manufacturer comprises a machine frame (7) and a control system (3), and is characterized in that a straightening mechanism (1), a looping mechanism (2), a stranding mechanism (4), a cutting mechanism (5) and a fuse-discharging mechanism (6) are arranged on the top surface of the machine frame (7) in sequence from the left to the right, wherein the straightening mechanism (1) is used for straightening an alloy bare copper lead; the looping mechanism (2) is used for looping the lead; the stranding mechanism (4) is used for stranding the lead; the cutting mechanism (5) is used for cutting the manufactured fuse; the fuse-discharging mechanism (6) is used for pulling the fuse out; fixed winding needles (13) in the straightening mechanism (1), and the looping mechanism (2), a stranding wheel (21), a stranding arm (19) and a moveable winding needle (20) in the stranding mechanism (4), a pair of pneumatic shears (23) in the cutting mechanism (5), and a pneumatic finger clamp (24) in the fuse-discharging mechanism (6) are arranged in parallel in multiple sets. According to the efficient internal fuse manufacturer, both fuse length and strand length can be automatically and precisely adjusted, the size precision of the manufactured fuse is high, and the internal fuse manufacturer has the advantage that the production efficiency is several times higher than that of the current automatic fuse manufacturer.

Description

technical field [0001] The invention belongs to the technical field of high-voltage capacitor manufacturing, and in particular relates to a high-efficiency internal fuse manufacturing machine. Background technique [0002] The internal components in the high-voltage capacitor are connected in series with the internal fuse to protect the high-voltage capacitor. It is a protection design and structure widely used in the high-voltage capacitor manufacturing industry. This inner fuse is usually made of Φ0.30~Φ0.50 tin-plated alloy copper bare wire. The welding connection part of the fuse and the capacitor element, the middle single-strand straight part is the melt part of the fuse, the length of the three-strand twisted part at both ends and the length of the middle single-strand straight part, and the length of each manufacturer's design, specification, and melt fuse. Different currents are different. [0003] The existing fuse making machines are divided into two types: manu...

AI Technical Summary

Problems solved by technology

[0003] The existing fuse making machines are divided into two types: manual fuse machine and automatic fuse machine. From the design structure, the length of the three-strand winding part cannot be adjusted, which makes the versatility of the equipment poor. The second is production efficiency. Low, the output of manual fuse machine is about 1000 pieces, and the output of automatic fuse machine is about 2000 pieces, the production efficiency is low
