Abstract

The invention discloses a cold heading device and process for pipe nuts. The device comprises a cutting-off mechanism, a feeding mechanism, a transfer mechanism and six molds. The positions of the feeding mechanism and the cutting-off mechanism are corresponding, and the transfer mechanism moves and transfers materials between the feeding mechanism and the molds. The molds comprise a first mold for pre-heading chamfering, a second mold for forming rod diameters, a third mold for pre-heading head hexagonal shapes, a four mold and a fifth mold for inverted extrusion of inner holes and fine heading of the head hexagonal shapes and a sixth mold for punching holes. The six molds are arranged successively. According to the device and the process, expensive hexagonal rods are not needed to be used as raw materials, so that the cost is saved; station materials are formed directly in the molds, so that the process is simple; the material usage rate is high, and compared with the prior art, the amount of raw materials required by a single pipe nut is saved by half; the subsequent machining process is not needed, the pipe nut production speed is improved to be 85 nuts/minute, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a pipe nut cold heading device and a cold heading process for ABS oil pipe mouth joints. Background technique [0002] Compared with ordinary nuts, the pipe nut has a long sleeve shape with an inner through hole and an outer thread on its shaft, and has a pipe thread on the outside that engages with the thread of the oil pipe joint, and the pipe nut in the ABS oil pipe port includes hexagonal shape and cylindrical shape. There are two parts in shape. In the prior art, workers directly use hexagonal bars as raw materials to produce pipe nuts, so there are the following problems: [0003] 1. The raw material is the high cost of hexagonal bar; [0004] 2. The process is complicated, and it is necessary to switch between the hexagonal fixture and the round material fixture according to the different processing parts during machining; [0005] 3. Using machining technology, the machi...
