Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] A cold heading manufacturing method for radiator connectors, comprising the following steps:

[0021] A. Reference figure 1 , using a metal rod as a raw material, the diameter of the metal rod is 27mm, and cutting the metal rod into segments to form metal segments;

[0022] B. Reference figure 2 , using a cold heading machine to upset the metal section in step A, so that the diameter of the metal section reaches 29mm;

[0023] C. Reference image 3 , place the upset metal segment in step B in the first mold, and use the cold heading machine equipped with the first die head to upset the upper center of the metal segment that has been upset in step B. The upper notch is Rounded truncated shape, the angle between the side of the rounded pedestal and the horizontal plane is 45°, and the diameter of the metal segment after the...

Abstract

A cold-heading manufacturing method for a radiator connector includes the steps: A, using a metal rod as a raw material and cutting the metal rod into sections to form metal sections; B, heading the metal sections in the step A by using a cold header; C, heading an upper notch at the center of the upper end of each headed metal section in the step B; D, heading a lower notch at the center of the lower end of each metal section treated in the step C; E, placing each metal section treated in the step D in a third die, and respectively stretching and notching the upper notches and the lower notches by using a cold header provided with a third die head; and F, placing each metal section treated in the step E in a fourth die, and punching the upper notches or the lower notches of the metal sections treated in the step E by using a cold header provided with a fourth die head. The radiator connector is formed by means of cold heading, materials are saved, and precision can be accurately controlled.

Description

(1) Technical field [0001] The invention relates to a manufacturing method for cold heading forming of radiator connectors. (2) Background technology [0002] Radiator connectors are essential parts for non-industrial radiator connections, such as Figure 7 As shown, the radiator connector is in the shape of a cylinder with protrusions on the inner wall. In the prior art, radiator connectors are usually made by casting or other methods, the precision is not enough, and the workpiece is relatively rough. (3) Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing manufacturing methods of radiator connectors, the present invention provides a cold heading manufacturing method of radiator connectors that saves raw materials and has high precision. [0004] The technical solution of the present invention to solve the technical problem is: a cold heading forming manufacturing method of radiator connectors, comprising the followin...
