Die Structure for Reducing Punch Wear of Hot Formed Steel Plate

Abstract

The invention relates to a die structure for reducing the thermal forming steel plate punch wearing. The die structure comprises an upper die and a lower die seat; the upper die is provided with an upper die punch, and the lower die seat is provided with a lower die punch concave die sleeve. The die structure is characterized in that a spiral lubrication guide pipe wraps the upper die punch; a lubrication guide pipe is hollow, and a gap is arranged in the wall of the lubrication guide pipe in the length direction; lubrication oil / liquid pipelines are arranged on one side of the upper die punch, one ends of the lubrication oil / liquid pipelines are fixed to the base mounting surface of the upper end of the upper die punch, and the other ends of the lubrication oil / liquid pipelines are fixed to the upper die; all the lubrication oil / liquid pipelines gather to form a main pipeline connected to a lubrication source; one ends of the lubrication oil / liquid pipelines are connected to one end of the lubrication guide pipe in a clearance fit manner, and the other end of the lubrication guide pipe wraps the upper die punch spirally and is opened. The structure has the advantages that on the premises that additional cost is omitted and the producing efficiency is guaranteed, the punch can be lubricated effectively.

Description

technical field [0001] The invention relates to a die structure for reducing the wear of a hot-formed steel plate punch, in particular to a die structure for performing a punching process for high-strength and ultra-high-strength steel plates after hot-forming treatment, belonging to the category of hot-forming steel plates. Separation technology field. Background technique [0002] High-strength steel plates have high strength, especially in normalized or normalized and tempered state, and have high comprehensive mechanical properties. The application of high-strength steel plates is an effective means to ensure lightweight 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 an emerging thing, the production process of hot-formed steel plate is different from that of ordinary high-strength steel plate. The production p...

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
