Abstract

The invention discloses a ratchet pin of a pair of box joint type water pump pliers, which comprises iron, nickel and molybdenum mixed powder and a binder. The binder contains 15-24% of medical paraffin wax, 10-15% of mineral wax, 30-60% of high-density polyethylene and 15-29% of EVA (Ethylene Vinyl Acetate) resin. The manufacture method of the ratchet pin of the box joint type water pump pliers comprises the following steps of: placing the iron, nickel and molybdenum mixed powder and the binder together in a two-roller rubber refining machine to obtain feed with mobility; placing the feed in an injection forming machine and injecting to form a blank; placing the blank in a tri-polyethylene solution to be dissolved and degreased; taking out the blank and drying; and finally, placing the blank in a vacuum furnace to be sintered and cooled. The manufactured ratchet pin of the box joint type water pump pliers has the advantages of high intensity, simple manufacture process and low manufacture cost.

Description

technical field [0001] The invention relates to a gill-piercing water pump pliers ratchet pin and a manufacturing method thereof. Background technique [0002] In modern production, life and work, various tools such as water pump pliers are often used. Traditional water pump pliers are not only bulky, but also difficult to expand and contract the size of the jaws, inconvenient to operate, and difficult to carry. In this way, a new type of special gill-piercing water pump pliers with straight mouth and teeth that is easy to operate and easy to carry naturally came into being. However, the ratchet pin, the core component, requires extremely high material strength and other mechanical properties and has a complex structure. It is difficult for general materials to meet its requirements. Strength requirements and performance are difficult to process, and the cost is extremely high. Contents of the invention [0003] The object of the present invention is to provide a ratchet...
