Manual making method of spiral lining plate model

Abstract

The invention discloses a manual making method of a spiral lining plate model. The manual making method of the spiral lining plate model comprises the steps that a three-dimensional pattern of a spiral lining plate casting is made by three-dimensional software; multiple division datum planes which are parallel to a basic datum plane are set on the model according to the height of the three-dimensional pattern of the spiral lining plate model; an outline sketch is formed in the three-dimensional pattern of the spiral lining plate model according to the intersection lines of the set division datum planes and the three-dimensional pattern of the spiral lining plate model; appropriate spiral lining plate model boards are selected according to the actual casting requirements; inner arcs and outer arcs of all the boards are processed by a plane; and corresponding model outline lines are marked at the two ends and the arc face of each board according to the model outline sketch, a model basicpart is processed by the plane layer by layer according to the marked model outline lines, and the final model with the complex curved surface is obtained. According to the manual making method of the spiral lining plate model, the model outline lines are processed, then smooth transition is conducted, the curved surface is obtained, the manual making method of the spiral lining plate model has the advantage of being low in production cost, the production efficiency is high, and the accuracy of the curved surface model is high.

Description

technical field [0001] The invention relates to the technical field of making models for casting, in particular to a method for manually making a spiral liner model. Background technique [0002] It is well known that the model is the basic tool of casting, and the model has an important influence on the quality of the casting. With the large-scale and multi-functional development of the spiral stirring mill, the contour surface of the spiral liner increases. The basic characteristics of the large-scale spiral liner model are large outline size, uneven wall thickness, difficult to measure the size, and difficult to manufacture. At present, most of the large-scale spiral liner models are made by CNC lathes, and the production cost is high. Contents of the invention [0003] In order to overcome the deficiencies in the background technology, the invention discloses a manual manufacturing method of a spiral liner model, which can effectively ensure the accuracy of the model...
