Embodiment Construction

[0020] Refer to attached picture. The present invention adopts the round wool as the raw material. First, the round wool is subjected to spheroidizing annealing treatment, and then the round wool after the spheroidizing and annealing is subjected to phosphate film surface treatment, and then finely drawn and sized, and then the finely drawn and sized The round finished material is cut into individual hose joint core blanks 1, and then the hose joint core blank 7 is made by cold pier machine according to the following six-station cold pier method:

[0021] (1) Automatically feed the hose joint core blank into the mold of the first station of the cold heading machine with clips, level one end of the hose joint core blank, and form a natural chamfer 11 at the corner, after turning 180 °, the hose joint core blank is automatically sent into the mold of the second station of the cold heading machine with a clip, the other end of the hose joint core blank is leveled, and a natural c...

Abstract

The invention provides a method for manufacturing a hose connector core, which comprises the following steps of: performing spheroidizing annealing on a wire rod blank material serving as a raw material; performing phosphate coating surface treatment on the wire rod blank material subjected to spheroidizing annealing; performing fine drawing sizing, and cutting a wire rod finished product material subjected to fine drawing sizing into single hose connector core blank materials; and manufacturing the blank of the hose connector core by using a seven-station cold heading method and a cold heading machine. The wire rod material is used for replacing a straight bar material and a broken material, so that the requirement of multi-station cold heading continuous production can be met, and the loss of a material head and a material tail is reduced; stations are reasonably designed, so that the physical property and the quality of a product are improved, and the product has good surface appearance; a material part is easily subjected to plastic deformation in the cold extrusion process, and the loss of a die is low; and finish machining production speed is doubled.

Description

technical field [0001] The invention relates to the field of a method for manufacturing a hose joint core. Background technique [0002] Nowadays, with the continuous progress of industrial economy at home and abroad, the use of hoses for plastic machines, excavators, and automobiles has developed rapidly, making the demand for hose connectors used at both ends of hoses very large. It has also created a huge hose joint market, and the hose joint core as a part of the hose joint has a very large market. However, at present, the main processing method of the hose joint core is to complete the processing with straight bar material, single-station cold heading and other processes, which is not only slow, but also has the disadvantages of high processing cost, large energy consumption, and high total cost. [0003] The hose joint core is in the shape of a long round tube, with a connector connected to the nut at one end, and a connecting pipe section that is connected to the hos...
