Radial elastic loading device for skew rolling bar

Abstract

The invention relates to the technical field of metal plastic forming technologies and equipment and provides a radial elastic loading device for a skew rolling bar. The device is formed by mounting aplurality of independent elastic loading units on a rack and can be applied to loading bars with different lengths. The device is in radial loading, a base is in an annular whole body type, and the device has the characteristics of compact structure, small acting force to the rack and small occupying space; and as elastic contact between the bar and the device has the effect of buffering vibration absorption, impact deformation and impact noise of the bar generated by swinging of the bar can be reduced in the skew rolling process. The radial elastic loading device has the advantages of good universality, compact structure, small occupying space, small bar deformation, low field noise and the like.

Description

technical field [0001] The invention relates to the technical field of metal plastic forming technology and equipment, in particular to a radial elastic feeding device for cross-rolled bars. Background technique [0002] Anode phosphor copper balls are widely used as electroplating anode materials in industrial fields such as printed circuit boards, hardware, and decoration. Due to the advantages of high production efficiency, low energy consumption and cost, stable quality, excellent product electroplating performance, and clean and pollution-free production methods, room temperature skew rolling technology has been widely used and has become an important technical means for the production of anode phosphor copper balls. [0003] At present, the process of cross-rolling anodic phosphor copper balls is as follows: the rods produced by continuous casting are transported to the site in the form of discs, first cut by flying shears, then straightened by a straightening machine,...

Problems solved by technology

[0004] Due to the composite motion of radial high-speed rotation and axial linear feed of the long and thin bar, there is a high-speed impact between the bar and the feeding support device. ), on the one hand, due to the rigid contact between the feed roller system and the copper rod, the copper rod is easy to swing at high frequency and low in the feed support device, resulting in high noise at the production site, serious deformation of the copper rod itself, and reduced surface quality of the copper ball , The surface of the parts in contact with the copper rod is severely worn; on the other hand, because the feeding method is axial feeding, the on-site production line is too long and the length of the feeding copper rod is shortened, resulting in reduced efficiency and more feed heads, etc. question

At the same time, because the base of each unit is not integral and independent, the structure is not compact, the device rigidity is low, and the interchangeability is poor.
