Die structure for reducing punch wear of hot-formed steel plate

Abstract

The invention relates to a die structure for reducing abrasion of hot forming steel plate punches. The die structure comprises an upper die and a lower die holder. The upper die punches are arranged on the upper die, and a lower die piecing female die sleeve is arranged on the lower die holder. The die structure is characterized in that spiral lubricating guide wires are wound on the upper die punches, are solid guide wires and are made of cotton swabs or hard filter paper; a lubricating oil / lubricating liquid pipeline is arranged on a side of each upper die punch with lubrication requirements, one end of each lubricating oil / lubricating liquid pipeline is fixed onto a base mounting surface at the upper end of the corresponding upper die punch, and the other end of each lubricating oil / lubricating liquid pipeline is fixed onto the upper die; all the lubricating oil / lubricating liquid pipelines are gathered to form a main pipeline, and the main pipeline is connected with a lubrication source; an end of each lubricating oil / lubricating liquid pipeline is connected with one end of the corresponding lubricating guide wire by a hoop, and the other end of each lubricating guide wire is wound on the corresponding upper die punch along the circumferential direction of the upper die punch. The die structure has the advantages that the punches can be effectively lubricated on the premise that extra costs can be omitted and loss of the production efficiency can be prevented.

Description

technical field [0001] The invention relates to a mold structure for reducing the wear of hot-formed steel plate punches, especially a mold for punching high-strength and ultra-high-strength steel plates after hot-forming treatment, which belongs to the field of hot-formed steel plates Separation of technical fields. 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 steel plate usually inc...

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
