Die system for lubricating the trimming edge of hot-formed steel plate

Abstract

The invention relates to a die system for lubricating hot-forming steel plate trimming edges. The die system comprises an upper die, a pressure plate and an upper die trimming insert, and is characterized in that a plurality of vertical downward oil grooves are evenly arranged between the mounting bottom surface of the upper die trimming insert and one trimming edge, and the oil grooves are arranged in one side face, in contact with the pressure plate, of the upper die trimming insert; the upper end of each oil groove extends to the mounting bottom surface of the upper end of the upper die trimming insert, and the lower end of each oil groove is in circular arc transition with the side face of the upper die trimming insert; a lubricating oil / lubricating fluid pipe is arranged on one side of the upper die trimming insert with each edge needing to be lubricated, one end of each lubricating oil / lubricating fluid pipe is fixed on the top of the corresponding oil groove, and the other end of each lubricating oil / lubricating fluid pipe is fixed on the upper die; all the lubricating oil / lubricating fluid pipes gather into a main pipe which is connected with a lubricating source. Under the premise of no increase of additional cost and no loss of production efficiency, the trimming edges are lubricated effectively.

Description

Technical field [0001] The invention relates to a die system for lubricating the trimming edges of hot formed steel plates, in particular to a die used for trimming high-strength and ultra-high-strength steel plates after hot forming treatment, which belongs to the separation technology of hot formed steel plates field. Background technique [0002] High-strength steel plate has high strength, especially in normalizing or normalizing and tempering state. It has high comprehensive mechanical properties. The application of high-strength steel plate is an effective means to ensure lightweight and collision safety at the same time. Therefore, it is used in large ships and bridges. , Power station equipment, medium and high pressure boilers, high pressure vessels, locomotives, cranes and other engineering industries. As a new thing, the production process of hot formed steel plate is different from ordinary high-strength steel plate. The production process of hot formed steel plate u...

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
