Description

An automatic riveting device for pins

【Technical field】

The utility model belongs to the field of chain manufacturing and processing equipment, in particular to an automatic riveting device for pin pieces.

【Background technique】

The pin is one of the important parts of the chain, which is assembled by two connecting pins and an outer chain plate. The pin piece mainly plays the role of connecting the two ends of the chain on the chain, and is convenient for disassembly simultaneously. When the equipment or instrument needs to replace the chain, the old chain can be quickly replaced by removing the pin. Although the pin piece is easy to disassemble, it must be processed by the riveting head to make it firm and not easy to fall off when it is connected to the chain to achieve the same use as other chain links. Therefore, the pin riveting head is an indispensable process in chain manufacturing. Its function is mainly to fix the outer chain plate of the pin piece to prevent the chain piece from falling off during the use of the chain, which will cause the running equipment or instrument to stop working halfway. There are three types of riveting heads for pins: one is two-sided riveting, the other is square riveting, and round riveting. Now the technology of domestic pin riveting on both sides and square riveting is relatively mature, and they are common in various factories. However, the technology of round riveting is not very mature, and there are many defects.

At present, the existing domestic pin piece round riveting equipment is driven by a cam or gear structure. During the transmission process, due to the large meshing gap of the gears and the wear of the copper sleeve, the positioning accuracy of the pin piece is not high, and the size of the riveting head is uneven. The traditional point-type arc-shaped round rivet head is used on the round rivet head, which has a short service time and complicated processing technology, and requires a lot of spare parts during use. In terms of the environment, the traditional round riveting equipment is relatively noisy, which is harmful to human safety; in terms of equipment versatility, the traditional pin riveting equipment can only process pins of one specification. Pins with longer distances require the purchase of new equipment. To sum up, the traditional pin piece round riveting equipment is inconvenient to operate, requires a lot of maintenance, and has many wearing parts. At the same time, the versatility of the equipment is poor.
