But quick replacement mould's aluminium alloy shaping processing equipment
Technical Field
The invention belongs to the technical field of aluminum profile machining, and particularly relates to aluminum profile forming and machining equipment capable of quickly replacing a die.
Background
The aluminum profile is a nonferrous metal material which is obtained by casting aluminum and a few metals such as magnesium and the like and is subjected to pressure casting into a target shape through rolling, extrusion, stretching or forging extrusion and the like.
However, the existing aluminum profile forming and processing equipment often has the following problems when in use:
1. in the extrusion molding process of the aluminum profile, an adaptive aluminum profile mold is usually required to be used for processing to extrude the aluminum profile with a target shape, if the aluminum profiles with different shapes are required to be processed, the corresponding mold is required to be replaced, however, when the mold is replaced, a hydraulic device in the compression molding processing equipment is usually required to be closed, so that the replacement speed of the aluminum profile mold is low, and the overall efficiency of the compression molding processing of the aluminum profile is reduced;
2. before the aluminum profile profiling enters the profiling process, the heated aluminum bar needs to be conveyed to an extrusion processing position, and a driving source of a conveying and supplying mechanism for heating the aluminum bar needs to be independently arranged, so that the driving cost of the aluminum profile profiling processing and the use cost of equipment are increased;
3. after the aluminum bar is subjected to profiling processing, the extruded aluminum profile is required to be conveyed to a subsequent process part, and at present, a plurality of rotating rollers are generally adopted in the equipment to realize the conveying of the extruded aluminum profile, however, the conveying mode is also required to be provided with a driving mechanism, so that the use energy consumption cost of the equipment is increased, and the subsequent processing of the aluminum profile can be possibly influenced under the passive conveying mode without the driving mechanism.
