Description

Device for removing waste materials generated in punching of stamping die

Technical Field

The utility model relates to a stamping die technical field specifically is a clear away device of waste material that stamping die punched a hole.

Background

The stamping die is a special process equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in cold stamping processing, and is called a cold stamping die (commonly called a cold stamping die). Stamping is a press working method in which a die mounted on a press is used to apply pressure to a material at room temperature to cause separation or plastic deformation of the material, thereby obtaining a desired part.

Modernization of mold manufacturing technology is the foundation of mold industry development. With the development of science and technology, advanced technologies such as computer technology, information technology, automation technology and the like are continuously permeating, intersecting and fusing into the traditional manufacturing technology, and are transformed to form the advanced manufacturing technology. The novel tapping technology in the stamping die guides a plurality of stamping manufacturers to reduce the cost and cause a rush purchase hot tide.

In the past in the production of deep-drawn or heavy-drawn workpieces, pressure-resistant (EP) lubricating oils have been considered the best choice for protecting the dies. Sulfur and chlorine EP additives have long been mixed into virgin oils to improve mold life. However, with the advent of new metals, high strength steels, and stringent environmental requirements, the value of EP oil-based lubricants has diminished, even lost the market.

At high temperature high strength steel forming, EP oil based lubricants lose their properties and do not provide physical mold protection membranes in extreme temperature applications. While the IRMCO high solids polymer lubricant, which is a very warm type, can provide the necessary protection. As the metal deforms in the stamping die, the temperature continues to rise and the EP oil-based lubricating oil thins, in some cases reaching a flash point or burning (smoking). IRMCO high molecular weight polymeric lubricants generally start to be much less thick when sprayed on. As the temperature increases during the forming process, it becomes thicker and tougher. In fact, high molecular weight polymer extreme lubricants are "hot-seeking" and tend to stick to metals, forming a friction-reducing membrane. This protective barrier may allow the work piece to be stretched without cracking and bonding during the forming of the most demanding work piece, thereby controlling friction and metal flow. The die is effectively protected, the service life of the die is prolonged, and the stamping strength is improved.

In order to solve the problem that a certain amount of waste materials are accumulated in the punched holes in the punching process and need to be cleaned in time, a device for cleaning the waste materials punched by the punching die is provided.
