An intelligent temperature control device for eccentric body tiles of a mechanical press

Abstract

An intelligent temperature control device for an eccentric body tile of a mechanical press comprises a lubricating system for lubricating the eccentric body tile, and a heat dissipating system for dissipating head, wherein the lubricating system is used for reducing heat produced by friction between the eccentric body tile and a mandrel; the heat dissipating system is used for dissipating the heatproduced by the eccentric body tile; and the lubricating and the heat dissipating system are matched to completely intelligently control the temperature of the eccentric body tile. The device has theadvantages of being high in special temperature decreasing performance, unique in structure, time to dissipate heat, and efficient; the lubrication to a heating source of the eccentric body tile is improved so as to decrease the heating capacity of the eccentric body tile; and moreover, the heating source of the eccentric body tile can be centrally cooled while the heating capacity is decreased,so that the heat can be quickly dissipated.

Description

technical field [0001] The invention relates to the technical field of mechanical presses, in particular to an intelligent temperature control device for eccentric body tiles of a mechanical press. Background technique [0002] At present, a sliding friction pair is formed between the eccentric body shoe and the mandrel of the mechanical press and generates heat. Existing eccentric body tiles are generally lubricated with thin oil. For eccentric body tiles with low speed or low mechanical performance requirements of the press, general lubrication can meet the requirements. However, for high-speed, precision mechanical presses or automated production lines, the friction surface has the highest specific pressure and the largest sliding friction when the press slider moves close to the bottom dead center and is close to the eccentric side under the impact of heavy loads. The heat generated in different parts of the eccentric body tile is different, so general lubrication canno...

AI Technical Summary

Problems solved by technology

However, for high-speed, precision mechanical presses or automated production lines, the friction surface has the highest specific pressure and the largest sliding friction when the press slider moves close to the bottom dead center and is close to the eccentric side under the impact of heavy loads. The heat generated in different parts of the eccentric body tile is different, so general lubrication cannot meet its requirements

In order to improve the lubricating effect, people have made many improvements to the eccentric body tile, among which the lubricating effect is better when the lubricating oil line is set on the eccentric body tile, but the current lubricating oil line on the eccentric body tile is evenly distributed, and its structure is similar to that of Force does not match when working

The lubricating effect has not been significantly improved

In addition, once the press heats up too much, the temperature of the entire eccentric body will rise

In the prior art, there is no heat dissipation for the eccentric body tile while the lubrication effect is not good, so that the eccentric body tile cannot be cooled well

As a result, the gap between the eccentric body pad and the mandrel gradually decreases, further accelerating wear and even grinding

Seriously, the eccentric body tile and the mandrel are sintered and locked together, and the fixing bolts at both ends of the mandrel are cut off, causing serious damage to the machine tool and being forced to stop for maintenance.
