Aluminum profile extrusion die with extrusion channel push-back and blade anti-sticking functions

Abstract

The invention discloses an aluminum profile extrusion die with extrusion channel push-back and blade anti-sticking functions. The die comprises a shell communicating with an extrusion channel, whereinan extrusion plate driven by a first hydraulic cylinder is arranged in the shell; and the die further comprises an aluminum profile cutting mechanism, an aluminum profile sliding judgment mechanism,an extrusion channel push-back cleaning mechanism, a blade anti-sticking mechanism and a waste heat utilization mechanism. The die has the functions of extrusion channel push-back cleaning and blade anti-sticking, is high in automation degree and has a good popularization prospect.

Description

technical field [0001] The invention relates to the field of aluminum profiles, in particular to an aluminum profile extrusion die with the functions of pushback of extrusion lanes and anti-sticking of blades. Background technique [0002] Extrusion of aluminum profiles refers to the use of extrusion plates to force-extrude irregular aluminum ingots through an extrusion channel with a specific shape, and then use a cutter to cut the extruded aluminum profile from the exit of the extrusion channel, thereby A technique to obtain aluminum profiles with the same cross-sectional shape as the extrusion channel. [0003] After completing an extrusion operation, it is often necessary to clean up the residual aluminum in the extrusion channel before the next extrusion operation, otherwise the residual aluminum profile in the extrusion channel will be directly extruded during the next extrusion It falls into the next process, but the length of this part of the aluminum profile cannot...

AI Technical Summary

Problems solved by technology

[0003] After completing an extrusion operation, it is often necessary to clean up the residual aluminum in the extrusion channel before the next extrusion operation, otherwise the residual aluminum profile in the extrusion channel will be directly extruded during the next extrusion Dropped into the next process, but the length of this part of the aluminum profile cannot meet the requirements and cannot be used directly

At present, the residual aluminum profiles in the extrusion channel are basically cleaned by manual operation, which is not only time-consuming and laborious, but also has a great impact on the upgrade of automation.

[0004] At the same time, the inventor found that due to the high temperature of the extruded aluminum profile, there is a certain degree of stickiness between the blade and the aluminum profile after the blade is cut. The viscosity of aluminum profiles to the blade is different. Therefore, when developing the push-back cleaning structure of the automatic extrusion channel, it is not possible to use the method of starting the push-back cleaning structure after the blade cuts off for a fixed period of time, otherwise it is easy to cause the push-back cleaning structure to accidentally touch the aluminum. profile, resulting in its damage, it is necessary to have a new way to accurately judge the time when the blade falls into the receiving plate, so as to start the pushback cleaning structure
