Guide sleeve hot forging forming die and assembling method

Abstract

The invention provides a guide sleeve hot forging forming die and an assembling method, the guide sleeve hot forging forming die comprises an inner die structure used for forming an inner hole of a guide sleeve, the inner die structure adopts an inner die upper structure and an inner die lower structure which are detachable, and the inner die lower structure is made of a high-temperature-resistant material; the guide sleeve forming die comprises an inner die structure and an outer die structure used for forming the appearance structure of a guide sleeve, the outer die structure is matched with the inner die structure to achieve forming of the guide sleeve, the outer die structure comprises an inner ring structure and an outer ring structure which are connected in a nested mode, the inner ring structure is made of a high-temperature-resistant material, and the outer ring structure is made of a tough material. The split type design is adopted in the die, the die can be conveniently machined, the service life of the die can be prolonged, the product size precision can be improved, meanwhile, due to the fact that the wall thickness of the split part of the die is smaller than that of an integral part, die sleeve machining can be conveniently conducted through a steel blank, and the machining cost is reduced.

Description

technical field [0001] The invention belongs to the field of steel hot forging manufacturing devices, in particular relates to a guide sleeve hot forging molding die and an assembly method, and in particular relates to advanced preparation, processing and molding technologies of metal and non-metal materials. Background technique [0002] As a part of the construction machinery cylinder, the guide sleeve has a complex shape, and the traditional processing method requires a large amount of processing, a long processing cycle, large material loss, and high production costs. The hot extrusion forging method is used to roughly machine the billet to the characteristic shape before turning, which can reduce the amount of material processing and the processing cycle. [0003] Since the structure of the guide sleeve is a sleeve structure, in the process of hot extrusion forging, it is necessary to use the inner mold and the outer mold for stamping, and in order to ensure that it can...

Problems solved by technology

[0003] Since the structure of the guide sleeve is a sleeve structure, in the process of hot extrusion forging, it is necessary to use the inner mold and the outer mold for stamping, and in order to ensure that it can withstand the high temperature environment, it is necessary to ensure that the inner mold and the outer mold It can withstand high temperature, while the existing inner and outer molds usually adopt an integral mold structure. At this time, all molds need to be made of special materials, and the mold cost is high; and for different guide sleeves, they need to be replaced Complete set of molds
