A handmade method of spiral liner model

Abstract

The invention discloses a manual manufacturing method of a spiral lining plate model, which uses three-dimensional software to make a three-dimensional view of a spiral lining plate casting; according to the height of the three-dimensional view of the spiral lining plate model, the model is set with a number of division reference planes parallel to the base reference plane; In the three-dimensional view of the liner model, the contour sketch is formed according to the intersection line of the set division datum plane and the three-dimensional view of the spiral liner model; according to the actual casting requirements, the appropriate spiral liner model wood board is selected; the inside and outside of all wood boards are processed by a plane Arc; according to the outline sketch of the model, the corresponding model outline is marked on both ends of each plank and on the arc surface, and the model base is processed layer by layer according to the marked outline of each model to obtain the final Models of complex surfaces. The invention obtains a curved surface through a smooth transition after the model contour line is processed, and has the characteristics of low production cost, high production efficiency and high precision of the curved surface model.

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...
