Bevel lubricating mould system capable of reducing abrasion of thermoforming steel plate trimming cutting edge

Abstract

The invention relates to a bevel lubricating mould system capable of reducing the abrasion of a thermoforming steel plate trimming cutting edge. The bevel lubricating mould system comprises an upper mould, a pressing plate and an upper mould trimming insert, and is characterized in that the upper end of the upper mould trimming insert is an installation bottom surface, the lower end of the upper mould trimming insert is the trimming cutting edge, and an oil groove is arranged between the installation bottom surface and the trimming cutting edge; the oil groove comprises a first vertical surface and a second vertical surface, and the lower end of the first vertical surface is connected with the upper end of the second vertical surface through a chamfering surface; a lubricating oil / liquid pipeline is arranged on one side of each upper mould trimming insert of which the cutting edge needs lubricating, an oil inlet hole is formed in the upper end of the upper mould trimming insert, the lower end of the oil inlet hole transits to the first vertical surface through an inclined surface, and the outlet of the lubricating oil / liquid pipeline is fixed in the oil inlet hole. The bevel lubricating mould system can effectively lubricate the trimming cutting edge on the premise of not increasing the additional cost and not damaging production efficiency.

Description

technical field [0001] The invention relates to a slope lubricating mold system for reducing the edge wear of hot-formed steel plate trimming, especially a mold used for trimming high-strength and ultra-high-strength steel plates after thermoforming treatment, which belongs to thermoforming The technical field of separation of steel plates. Background technique [0002] High-strength steel plate has high strength, especially in the state of normalizing or normalizing plus tempering, it has high comprehensive mechanical properties. The application of high-strength steel plate is an effective means to ensure light weight and collision safety at the same time. , Power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, lifting machinery and other engineering industries are widely used. As a new thing, hot-formed steel plate is different from ordinary high-strength steel plate in its production process. The production process of hot-formed...

Problems solved by technology

However, in the process of mass production: (1) adding a sequence of oiling process increases the production cost; (2) considering the safety stock of production, it is often necessary to prepare the warehouse, even if the logistics principle of first-in-first-out is guaranteed, it often occurs The production interval is long, and the lubricating oil / lubricating fluid covered on the workpiece volatilizes and drips, resulting in insufficient lubrication or even no lubrication in the whole or a certain local area
