Embodiment 1

[0034] A large-scale sculpture ferrule lofting process method, specifically the artificial ferrule enlargement, the steps are as follows:

[0035] 1. Design a small draft of a plaster model.

[0036] 2. Ferrule

[0037] Prepare the materials used for the ferrule, wallpaper knife, cardboard, pencil, level ruler, hacksaw blade, 502 glue; if it is a small clay sculpture, it is best to make a plaster model by turning the mold so that you can draw lines on the model with a pencil.

[0038] Place the plaster model draft on the coordinate paper and fix it. Use a level and a pencil to layer the sculpture draft horizontally and vertically. The distance between layers depends on the complexity of the sculpture. After drawing all the layered lines with a pencil , Use a hacksaw blade to saw a thin groove along the layered line.

[0039] Cut the cardboard into small pieces of cardboard with a size of about 3cm×5cm, insert the small pieces of cardboard into the horizontal layer of the pla...

Embodiment 2

[0048] A large-scale sculpture ferrule lofting process method, specifically computer-aided manual ferrule enlargement, the steps are as follows:

[0049] 1. Collect contour circle data

[0050] Depending on the size, contour data can be collected in two ways

[0051](1) This method is mainly for small sculpture sketches. The height of the sculpture sketch is less than 50cm, and the contour data can be collected with a plane scanner; For layering, only the x and y axes are needed for the vertical layer. After drawing all the layered lines with a pencil, use a hacksaw blade to cut out the grooves on the vertical x and y axes, and then saw the horizontal layer directly. Put the outline on A4 or A3 paper to draw the outline, mark the x and y axes; scan the outline on the paper, use ps or cr software to enlarge the outline by 10 times, and then extract the outline and export the path file;

[0052] (2) If the size of the sketch is large, and the height of the sculpture sketch is ...

Abstract

The invention discloses a large sculpture loop lofting technological method. The method comprises the following two ways including manual loop lofting and computer-assisted manual loop lofting. The manual loop lofting way comprises the following specific steps that firstly, a plaster model draft is designed; secondly, loops are prepared; thirdly, plywood loops which are ten times bigger are obtained; fourthly, the outline loops are assembled; and fifthly, a plaster sculpture is prepared. The computer-assisted manual loop lofting way comprises the steps that firstly, data of the outline loops are acquired; secondly, the outline data are processed; thirdly, the outline loops are assembled; and fourthly, the plaster sculpture is prepared. According to the large sculpture loop lofting technological method, lofting data are scientific and accurate, and the original effect of the sculpture art can be better guaranteed; and the construction period can be shortened, and raw and auxiliary materials can be saved. The large sculpture loop lofting technological method is reasonable in design and has quite good practical application and popularization value.

Description

technical field [0001] The invention relates to a method for making a lofting model of a large-scale artistic casting sculpture, specifically two methods of enlarging a sample of an artificial ferrule and enlarging a sample of a artificial ferrule aided by a computer. Background technique [0002] Lofting and making models of large-scale sculptures is an important process link in the production of large-scale artistic castings. At present, the lofting production models of large-scale sculptures mainly adopt two categories: mud-type lofting and plaster-type lofting of welded steel structure skeleton. The specific method is to first design a small plaster or clay draft of a large sculpture, measure the size, then use steel to weld the skeleton of the large sculpture, and then apply clay or plaster to enlarge the sample. This is the process method mainly used in the industry to make large-scale sculpture models at present. Then the mold is turned over, and then cast. The mai...
