Bevel lubricating die structure for reducing thermal forming steel plate trimming blade wearing

Abstract

The invention relates to a bevel lubricating die structure for reducing the thermal forming steel plate trimming blade wearing. The structure comprises an upper die, a press plate and an upper die trimming insert block; the press plate is arranged on the upper die and contacts with the upper die trimming insert block. The structure is characterized in that the upper end of the upper die trimming insert block is a mounting bottom, the lower end of the upper die trimming insert block is a trimming blade, and an oil tank is arranged between the mounting bottom and trimming blade of the upper die trimming insert block and is arranged on one side of the upper die trimming insert block contacting with the press plate; the oil tank comprises a first vertical surface and a second vertical surface; the first vertical surface is far from the center of the die and is crossed with the mounting bottom of the upper end of the upper die trimming insert block perpendicularly; the second vertical surface is perpendicular to the trimming blade surface of a workpiece and is located on one side adjacent to the center of the die; the lower end of the first vertical surface and the upper end of the second vertical surface are connected through a chamfer. The structure has the advantages that on the premises that additional cost is omitted and the producing efficiency is guaranteed, the trimming blade can be lubricated effectively.

Description

technical field [0001] The invention relates to a slope lubricating mold structure for reducing the wear of edge trimming of thermoforming steel plates, in particular to a mold 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...

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
