Abstract

The invention discloses a Pro/E-based warp knitting machine cam contour curve generation method for designing and manufacturing a substitute of an abraded warp knitting machine cam. The method comprises the following steps: (1) measuring contour data of the abraded warp knitting machine cam through a three-coordinate measurer; (2) importing the data into Pro/E to generate a three-dimensional model of a cam contour curve, and restoring flaws on contour lines of the model through Pro/E to generate a new three-dimensional cam model; (3) designing and manufacturing a cam casting mold according to the three-dimensional cam model; (4) pouring high-intensity casting alloy steel solution into the molding cavity of the cam casting mold, and cooling to obtain a cam casting; (5) performing thermal surface treatment on the cam casting, and removing post-casting stress to obtain the substitute. Due to the mode, the Pro/E-based warp knitting machine cam contour curve generation method can be used for quickly generating the three-dimensional mode of the abraded cam and manufacturing the cam substitute through casting; the cost is low, so that the production cost of an enterprise is effectively reduced.

Technical field
The present invention relates to and compile flower cam cutting technical field, particularly relate to a kind of warp knitting machine cam profilograph generation method based on Pro/E.
Background technology
Still there is a big difference apart from Foreign Advanced Lerel technically for China's warp knitting machine tool, therefore now some large knitting mills standbyly still mainly rely on external import, to promote industrial scale and quality product through setting up.And for some enterprises, owing to the reason such as to lack of capital, still use now older generation's import warp knitting machine, due to working life for a long time, the wearing and tearing of the experience wear of the portion parts on machine, particularly cam are particularly important, directly affects fabric quality.In order to machine can be made normally to produce, changing cam is one of the most effective approach, but from ordering accessory abroad, valency chromium is very expensive.For above situation, if with existing wear cam for research object, the substitute of wear cam can be produced, be the best method solved the problem.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art, a kind of warp knitting machine cam profilograph generation method based on Pro/E is provided, the three-dimensional model of wear cam can be generated fast, and by the obtained cam substitute of casting, cost is low, effectively reduces the production cost of enterprise.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of warp knitting machine cam profilograph generation method based on Pro/E, manufacture and design the substitute of the warp knitting machine cam worn and torn, comprise the steps:
1) three coordinate measuring engine measurement is adopted to have worn and torn warp knitting machine cam outline data;
2) by data importing in Pro/E, generate cam profile curve three-dimensional model, and then by Pro/E, the flaw on model silhouette line repaired, generate new cam three-dimensional model;
3) cam casting mould is manufactured and designed according to above-mentioned cam three-dimensional model;
4) by high-strength casting steel alloy solution casting in cam casting mould die cavity, obtain cam foundry goods after cooling;
5) Surface heat-treatent is carried out to cam foundry goods, remove the rear stress of casting, i.e. obtained described substitute.
In a preferred embodiment of the present invention, the quality proportioning of the chemical element that described high-strength casting steel alloy solution comprises and each element is: carbon 0.2%-0.5%, manganese 0.8%-1.5%, silicon 2%-5%, chromium 1%-4%, copper 3%-6%, nickel 1.2%-2.5%, aluminium 0.7%-1.4%, and all the other are iron.
In a preferred embodiment of the present invention, in the die cavity of described casting mould, be coated with graphite water coating.
The invention has the beneficial effects as follows: the present invention can generate the three-dimensional model of wear cam fast, and by the obtained cam substitute of casting, cost is low, and obtained cam substitute surface quality is high, profilograph precision is high.
