Embodiment Construction

[0007] The present invention demonstrates the implementation mode through its working principle. When using the detection tool, use the reference line on the left and right supports to align with the position line of the profile section, and fix it on the template with 502 glue for easy removal. , the right connecting pair 3, after sliding and adjusting the horizontal ruler 4 to the set left vertical ruler 2 and the right vertical ruler 8 at the same height, the 0 line on the horizontal ruler 4 is located in the middle of the left vertical ruler 2 and the right vertical ruler 8 with fastening Lock the screw, and slide to adjust the center line of the ruler 5 to coincide with the 0 line of the ruler 4, so that the distance from the lower end point of the ruler to the 0 line of the ruler is equal to the distance from the center line of the ruler to the 0 line of the vernier of the ruler. The lower end point touches the contour surface of pattern 11, read the sum Y0 of the integer...

Abstract

The invention relates to the field of iron casting, provides a tool for detecting mould outline curvature radius for large-scale casting production, and mainly solves the problems in manual manufacture and detection of large-scale moulds that measuring benchmark and process benchmark are difficult to align, and the overall dimension and the form-position tolerance are overproof. The tool can improve the whole outline curved surface precision by controlling the curvature radius on a related outline cross section curve, so as to ensure smooth transition of intersected surfaces, aesthetic appearance, and designed wall thicknesses of all parts, and meet the requirements on casting size, form-position tolerance, weight and appearance of a design graph.

Description

technical field [0001] The invention discloses a method for manufacturing a mold contour curvature radius detection tool, which relates to the field of iron and steel casting. It is suitable for testing the radius of curvature of the contour on the mold used in the production of large castings in sand foundries, judging whether the geometric shape of the contour on the mold is qualified, and ensuring that the contour surface of large castings meets the requirements of the design drawing. Background technique [0002] In the current iron and steel casting industry, large-scale casting molds are still mainly made of wood molds, which are made by hand. It is difficult to find the measurement benchmark and process benchmark. The size and shape tolerances are too large. Can not transition smoothly, affect the appearance. Sometimes in order to ensure the local effective wall thickness, the outline of the pattern is changed, which leads to an increase in weight and increases the c...
