Separation device for reducing punching wear of hot-formed steel plate

Abstract

The invention relates to a separating device for reducing punching abrasion of a thermoforming steel plate. The separating device comprises a static separating insert and a dynamic separating insert, a punching female die sleeve is arranged on the static separating insert, and a pressing block and a puncher pin are arranged on the dynamic separating insert. The separating device is characterized in that a through hole is formed in the pressing block, the through hole is formed by connecting a first through hole segment and a second through hole segment identical in diameter, and the first through hole segment is arranged on the upper portion of the second through hole segment; the puncher pin penetrates through the through hole, the puncher pin and the through hole are in interference fit, and internal threads are arranged on the inner surface of the second through hole segment; a mounting groove is reserved in the mounting bottom face at the upper end of the pressing block, and communicated with the through hole, the diameter of the mounting groove is larger than that of the through hole, a lubricating oil / lubricating liquid pipeline is arranged in the mounting groove, one end of the lubricating oil / lubricating liquid pipeline is fixed in the mounting groove, and the other end of the lubricating oil / lubricating liquid pipeline is fixed to the dynamic separating insert and then connected with a lubricating source. On the premise of not increasing additional cost or influencing production efficiency, the puncher pin is effectively lubricated.

Description

technical field [0001] The invention relates to a separation device for reducing punching wear of hot-formed steel plates, especially a die for punching high-strength and ultra-high-strength steel plates after hot-forming treatment, which belongs to the category 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 ...

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
