Processing method for conical surface of inclined base plate of aluminum extruder and correcting tool for conical surface of inclined base plate

Abstract

The invention discloses a processing method for a conical surface of an inclined base plate of an aluminum extruder. A correcting tool for the conical surface of the inclined base plate is used for processing the conical surface of the inclined base plate of the aluminum extruder. The processing method comprises the following steps of: firstly, fixedly connecting two to-be-processed inclined base plates with the correcting tool for the conical surface of the inclined base plate; secondly, roughly processing the conical surfaces of the inclined base plates on a boring mill; and thirdly, finely processing the conical surfaces of the inclined base plate workpieces on a vertical vehicle. In the invention, the method for correcting and processing the conical surface of the inclined base plate of the aluminum extruder is simplified and the processing efficiency for the inclined base plate is greatly increased. The invention also discloses the correcting tool for the conical surface of the inclined base plate.

Description

technical field [0001] The invention relates to a manufacturing method of an aluminum extruding machine, in particular to a method for processing a tapered surface of an inclined backing plate of an aluminum extruding machine. The invention also relates to a tool for correcting the conical surface of the inclined backing plate. Background technique [0002] Aluminum extrusion machine is a metallurgical equipment developed rapidly in recent years, mainly used for forming and extrusion of aluminum profiles. Aluminum profiles are widely used in aerospace, transportation, container and other industries. With the progress of industry, the demand for aluminum profiles is increasing, so the demand for aluminum extrusion machines is also increasing. [0003] The structure of the aluminum extrusion machine is complex, there are many kinds of parts, and there are many complicated and difficult-to-process material parts. The inclined pad is one of the most complicated parts. The incl...

Problems solved by technology

[0009] 1. The center of the workpiece is difficult to correct;

[0010] Since the center of the triangle iron is not the center of the conical surface of the workpiece, it is difficult to determine the center of rotation of the workpiece during processing. It is completely judged by marking lines, and there are errors. Especially in finishing machining, it is necessary to correct the center of the workpiece to be consistent with the center of rotation of the machine tool. The correction time longer

[0011] 2. The rough machining method of the cone surface is cumbersome and time-consuming;

[0012] Since the rough machining of the conical surface of the shape is realized by setting a triangle on the boring machine, the angle is satisfied by the swing angle of the universal milling head, so the spindle of the workpiece is not perpendicular to the conical surface, and the feeding direction of the spindle is not simply the X and Y directions, but Three-dimensional walking in space, and the feed rate needs to be calculated at the same time. The moving direction of the tool row must be consistent with the cone surface. Every time the circumference is processed, the X and Y direction movement of the spindle must be corrected, and then the circle is repeated for processing. The processing is cumbersome. The error is large, and the correction time and the number of tool passes are increased at the same time, the workpiece processing time is longer and the efficiency is low
