Problems solved by technology

[0002] At present, the processing method used in the processing of aluminum coils is difficult to eliminate the extrusion size tolerance and the mechanical vibration when two aluminum rods are connected, and in the process of extrusion molding of aluminum rods, because the mold temperature will drop after one processing, It will make the performance of the next extruded aluminum rod different from the performance of the previous injection-molded aluminum rod, and the difference in the overall performance of the aluminum rod will affect the post-processing; therefore, it is necessary to adjust the aluminum coil production method make improvements

Embodiment Construction

[0020] Below in conjunction with embodiment the content of the present invention is described in further detail.

[0021] A method for producing an aluminum coil, comprising the steps of:

[0022] Aluminum rod melting and casting: inject aluminum water into the mold cavity to form aluminum rods, and use ceramic filter elements to filter and purify impurities. After the aluminum rods are formed, they are uniformly annealed. Carry out heat preservation treatment;

[0023] Thermal peeling: heat the aluminum rod after injection molding, pass the formed aluminum rod through the peeling machine, and use the scraper of the peeling machine to peel off the surface of the aluminum rod to remove the surface layer with more impurities and poor performance part;

[0024] Extrusion: put the aluminum rod into the isothermal extrusion die, which needs to be placed in the heating system, and under the state of isothermal, constant pressure and constant speed, the working belt of the twisting...

Abstract

The invention discloses an aluminum coil pipe production method. The aluminum coil pipe production method comprises the following steps that melting and casting of an aluminum rod is carried out, andspecifically molten aluminum is injected into a mold cavity for pilot injection molding; hot peeling is carried out, wherein the aluminum rod subjected to pilot injection molding is heated to remove the surface parts with many impurities and poor performance of the aluminum rod; extrusion is carried out, wherein the aluminum rod is placed into an isothermal extrusion mold, and a twisting closing section working belt is added in front of a welding-closing cavity for extrusion; and cold drawing is carried out, and specifically cold-drawing processing is carried out by using a moving core head and a hard alloy mold. A large-processing-amount reducing-diameter wall-reducing mode is adopted by using the production method, so that the extrusion size tolerance and mechanical vibration during connection of the two aluminum rods are eliminated, and then the size and the wall thickness precision of a processed aluminum coil pipe can reach +/-0.03 mm.

Description

technical field [0001] The invention relates to the field of metal pipe processing methods, in particular to an aluminum coil production method. Background technique [0002] At present, the processing method used in aluminum coil processing is difficult to eliminate the extrusion size tolerance and the mechanical vibration when two aluminum rods are connected, and in the process of aluminum rod extrusion, because the mold temperature will drop after one processing, It will make the performance of the next extrusion-molded aluminum rod different from the performance of the previous injection-molded aluminum rod, and the difference in the overall performance of the aluminum rod will affect the post-processing; therefore, it is necessary to adjust the aluminum coil production method Make improvements. Contents of the invention [0003] The present invention aims at the above-mentioned technical deficiencies, and provides a method of reducing the diameter and wall of the lar...
