Abstract
The invention discloses a simple operation method for the benchwork scribing of a casting valve blank. The method comprises the steps of analyzing a valve blank casting sketch, drawing a scribing template drawing, making a scribing template, scribing with the scribing template and the like. By using the scribing template to scribe a casting valve, the method greatly saves the scribing time and reduces the scribing difficulty; moreover, whether an oil groove has the phenomena of casting deviation, oil ribs defect and the like or not and whether the wall thickness of each hole and the shape of the blank meet the design and use requirement or not can be detected during the scribing. The method has the advantages of high production efficiency, stable quality, shorter production period and mass production.
Description
Technical field
Present technique relates to a kind of simple operation method of benchwork scribing of casting valve blank.
Background technology
Foundry valve body blank has generally that oil groove is many, complex structure and out-of-shape, also has a large amount of hole systems to distribute alternately with oil groove simultaneously.---slide rule cun---taking into account relative dimensions such as oil groove, hole wall---line that for this class blank, the conventional method of pincers worker line is: look for benchmark.During line, because this kind valve body oil groove is more, and complicated irregular, need verification repeatedly, take into account a plurality of sizes.This shows, give a blank line, oil groove and Kong Yue time that needs of ruling many more more.However, because verification and the size of taking into account all are crucial comparatively speaking sizes, and less important size or oil groove shape are not easy to find when distant defective is arranged, during the workpiece that flows down so just might the assembling after processing uses because of the poorly sealed oil leakage phenomenon that occurs.
Summary of the invention
The technical problem that solves
For overcoming the deficiency of traditional scribble method, a kind of accurate, convenient, fast, reliable scribble method is provided, to make the line of foundry valve body blank under the prerequisite of ensuring the quality of products, shorten the line time, increase work efficiency after using this method, can produce in batches, can also fast find the Castingother defective of blank simultaneously.
Technical scheme
The present invention is achieved in that the defective at prior art, adopts and analyzes valve body rough-cast figure, and---drafting face mold figure---making face mold---is with the method for face mold line; And adopt following measure.
The one, the final processing request of analysis valve body rough-cast figure and part.
Line requirement according to valve body blank crossed process figure (see figure 1) and part, analyze oil groove distribution character, distribution of pores characteristic, external form characteristic, distinguish keypoint part and non-keypoint part, oil groove is casting and forms, following process no longer, hole wall must not be prepared for drawing face mold figure less than given size.
The 2nd, the design face mold
(1) sample sheet material is selected, because will take into account oil groove and each hole of valve body, needs to select material transparent, therefore selects lucite to make the material of face mold.
(2) draw template drawing,, draw face mold figure (see figure 2) according to analysis and processing request to part.
The 3rd, make face mold, according to face mold figure blanking, processing oil groove, part external form and each hole on precision machine tools such as vertical machining centre on request, and process the line datum line, the i.e. breach of 4 a * b, size a, b can set according to actual needs, and span generally is no more than 5mm.
Four are to use face mold, lie in workpiece on the flat bench after, smoothing big plane, oil groove place (this plane through mill processing) places face mold on the workpiece, aims at each oil groove, take into account the wall thickness in each hole after, stroke machining benchmark line.Check during line whether oil groove has situations such as inclined to one side, the oily muscle of casting is damaged, and whether the wall thickness in each hole, blank external form satisfy the design instructions for use.
Beneficial effect
Use face mold, not only can reduce the time of looking for benchmark, slide rule cun when ruling and taking into account other sizes in a large number with conventional method, and can reduce the line difficulty, use model to check whether to have the situation of casting flaws such as inclined to one side, the oily muscle of oil groove casting is damaged simultaneously, and whether the wall thickness in each hole, blank external form satisfy the instructions for use of part.
Description of drawings
Fig. 1 is a kind of foundry valve body crossed process process drawing
The face mold figure that Fig. 2 makes for this valve body
The specific embodiment
The embodiment of the invention: in conjunction with the line valve body of Fig. 1, the face mold explanation of Fig. 2.
Below in conjunction with accompanying drawing, concrete embodiment is elaborated:
The technological process of present embodiment:----making face mold---draws A, B datum line with face mold in conjunction with design drawing analysis line main points according to valve body line technical papers.
1, rules technical papers in conjunction with design drawing analysis line main points according to valve body.
1 (process drawing of crossed process) analyzed oil groove distribution character, distribution of pores characteristic, external form characteristic with reference to the accompanying drawings, finds out the line benchmark, and its mesopore 1, hole 2 are hole to be processed, and this road line will guarantee that hole 2 wall thickness are no less than given size.
2, design, making face mold
(1) sample sheet material is selected, because will take into account oil groove and each hole of valve body, needs to select material transparent, therefore selects lucite to make the material of face mold.
(2) draw template drawing, according to analysis and processing request to part, draw face mold figure (see figure 2), size on the template drawing except that the breach of profile, 4 a * b is the actual size on the design drawing, size a, b can set according to actual needs, and span generally is no more than 5mm, A, the B benchmark of the A on the template drawing, the corresponding part drawing of B benchmark; A on the face mold figure * b breach if any wearing and tearing, can be filed again in adjacent locations and repair gap in use for some time, so just can prolong the service life of face mold.
(3) make face mold, according to face mold figure blanking, processing oil groove, part external form and each hole on precision machine tools such as vertical machining centre on request, and process the line datum line, i.e. 4 a * b breach.Oil duct, hole and part trim line all are coated with red lead powder, with each actual oil duct, hole and profile on the convenient contrast workpiece.
3, use the face mold line
Workpiece is lain on the flat bench, and smoothing big plane, oil groove place (this plane is through milling processing) places face mold on the workpiece, aims at each oil groove, takes into account the wall thickness in each hole, draws A, B datum line in 4 a * b indentation, there of model.
Claims (1)
1. the method for operating of a benchwork scribing of casting valve blank, it is characterized in that: it may further comprise the steps:
The one, the final processing request of analysis valve body rough-cast figure and part.
Line requirement according to valve body blank crossed process figure and part, analyze oil groove distribution character, distribution of pores characteristic, external form characteristic, distinguish keypoint part and non-keypoint part, oil groove is casting and forms, following process no longer, hole wall must not be prepared for drawing face mold figure less than given size.
The 2nd, the design face mold
