Embodiment

[0017] Such as figure 1 , 2 , 3 and 4, taking as an example the new type of digital transmission connection terminal pin with a diameter of 3.46mm and a length of 16.1mm, it specifically includes the following steps:

[0018] 1. Material selection: choose a copper strip 31 with a width of 18mm and a thickness of 0.16mm, and place it on a swing feeding device. The feeding device mainly includes a feeding head 1 and a power shaft 14 for providing power. The feeding head 1 has a longitudinal feeding track 2 for shelving the strip material 3, and is characterized in that it also includes a feeding mechanism and a swing mechanism. Described feeding mechanism comprises the upper feeding roller 4 that is positioned at the described feeding track top and is positioned at the lower feeding roller 5 that fits with this upper feeding roller 4 below described feeding track, and described lower feeding roller 5 and drives its rotation The feeding drive shaft 6 is connected to the feed d...

Abstract

The invention relates to the field of pin piece manufacturing, in particular to a novel making process of a cylindrical pin piece of a digital transmission connection pin. The process comprises the following steps of: (a) selecting materials: selecting a copper strip with width of 18-27.5 mm and thickness of 0.16-0.22 mm, and placing the copper strip on a swinging feeding device; and (b) high speed precision stamping and deep drawing: feeding the copper strip meeting specifications to a deep drawing progressive die by the swinging feeding device; carrying out continuous deep drawing on the copper strip until an outer pipe finished product meeting the specifications are deeply drawn by a multi-station continuous die. The novel making process provided by the invention has the advantages as follows: the production efficiency is greatly increased, the direct production cost is reduced and high accuracy and stable quality of a product are guaranteed; good mechanical strength and transmission performance are also achieved; it is proved by test that parameters of the product, such as mechanical strength, anti-interference property and the like, all meet specifications and standards in the industry, and compared with a copper rod turned piece, the product has the advantages of more stable performance and strong signal transmission effect.

Description

technical field [0001] The invention relates to the manufacturing field of pin inserts, in particular to a manufacturing process of a novel cylindrical pin insert of a digital transfer connection terminal. Background technique [0002] The existing new type of digital transmission connection terminal cylindrical pin is made of copper rods and processed by a single-axis automatic lathe. This production process has a large loss of raw materials, high production costs, unstable product quality, and low process accuracy. high and low productivity. In the current shortage of resources, especially in the situation of advocating energy saving and consumption reduction, the traditional production process should be improved technically. Contents of the invention [0003] In order to solve the technical problems of high raw material loss and high production cost in the above-mentioned traditional process, the present invention provides a new process for manufacturing a cylindrical ...
