In the existing pliers head processing technology, when manufacturing pliers, the three elements on the pliers head are manually polished one by one with grinding wheels or abrasive belts, which has low processing efficiency and high labor intensity; grinding produces more processed iron. Chips and processing noise will cause great harm to the laborer's body. At the same time, there is a greater safety risk in manual grinding, which brings greater experience risk to producers and operators. The labor cost is greatly increased, and the profits generated by the pliers are further reduced. compression.

However, the clamping of the mechanical arm is overkill, and the loss is large, and the investment in equipment is high. For the traditional hardware manufacturing industry, its profit is originally low. Such a high investment in equipment is not suitable, and its production efficiency is limited. Due to the back and forth rotation of the mechanical arm and the clamping and picking, the efficiency is not high.
