Abstract
The invention discloses a method for cutting a casting head of a casting, and belongs to the field of casting. The method for cutting the casting head of the casting comprises the steps that 1, a cutting tool is prepared; 2, a gas cutting tool is started, and the casting head of the casting is preheated; and 3, when the temperature of the casting head of the casting is 350 DEG C to 450 DEG C, the casting head of the casting is cut, and therefore cutting work on the casting head of the casting is completed. A gas cutting gun is adopted as the cutting tool. According to the method for cutting the casting head of the casting, the problems that in a cutting method in the prior art, labor intensity is large, and production efficiency is low are solved, and therefore the labor intensity of staff is relieved, the cutting efficiency of the casting head of the casting is improved, the cutting effect is very good, machining is not needed later, and the quality of the casting is guaranteed.
Description
Technical field
The present invention relates to a kind of cutting method, particularly relate to a kind of cutting method of casting head of casting.
Background technology
Foundry goods is the metal forming object obtained by various casting method, namely the liquid metal smelted, preprepared casting mold is injected with cast, injection, suction or other casting methods, after cooling after the following process means such as polishing, the object with definite shape, size and performance obtained.
When carrying out moulding according to foundry goods, in order to the cast of follow-up metal liquid is convenient, usually can cast gate be set; and in order to prevent shrinkage cavity and porosity, exhaust and collection slag, rising head can be set usually, therefore; cast gate and rising head are absolutely necessary parts, and it is referred to as dead head.
Due to the form that dead head is not foundry goods, therefore, after sand removal work completes, dead head will be cut off.In prior art, usually adopt hammering to knock off method and dead head is removed, but the method is hand-manipulated, labour intensity is large, production efficiency is low.
Summary of the invention
For above-mentioned Problems existing, the invention provides a kind of cutting method of casting head of casting, to overcome the problem that cutting method labour intensity of the prior art is large, production efficiency is low, thus alleviate the labour intensity of employee, improve the cutting efficiency of casting head of casting, and cutting effect is also fabulous.
To achieve these goals, the technical scheme that the present invention takes is:
A cutting method for casting head of casting, wherein, comprising:
(1) cutter is prepared;
(2) start gas cutting apparatus, preheating is carried out to casting head of casting;
(3) when the temperature of casting head of casting reaches 350 ~ 450 DEG C (as 350 DEG C, 370 DEG C, 390 DEG C, 400 DEG C, 420 DEG C, 440 DEG C, 450 DEG C etc.), casting head of casting is cut, thus completes the cutting work of casting head of casting;
Wherein, what described cutter adopted is cutter.
The cutting method of above-mentioned casting head of casting, wherein, described cutter is oxygen-natural gas cutter.
The cutting method of above-mentioned casting head of casting, wherein, the oxygen purity that described cutter uses is greater than 99%.
The cutting method of above-mentioned casting head of casting, wherein, when carrying out preheating, the distance between the inner cone front end of the flame that described cutter produces and described casting head of casting is 3mm.
The cutting method of above-mentioned casting head of casting, wherein, when cut be less than the casting head of casting of 5mm thickness time, described cutter tilts backwards 6 ~ 8 ° (as 6 °, 7 °, 8 ° etc.); When the casting head of casting of cutting 5 ~ 30mm thickness, described cutter is perpendicular to described casting head of casting; When cut be greater than the casting head of casting of 30mm thickness time, described cutter turns forward 6 ~ 8 ° (as 6 °, 7 °, 8 ° etc.).
Technique scheme tool has the following advantages or beneficial effect:
The cutting method of casting head of casting provided by the invention comprises: (1) prepares cutter; (2) start gas cutting apparatus, preheating is carried out to casting head of casting; (3) when the temperature of casting head of casting reaches 350 ~ 450 DEG C, casting head of casting is cut, thus complete the cutting work of casting head of casting; Wherein, what cutter adopted is cutter; The cutting method of this casting head of casting overcomes the problem that cutting method labour intensity of the prior art is large, production efficiency is low, thus alleviate the labour intensity of employee, improve the cutting efficiency of casting head of casting, and cutting effect is also fabulous, follow-up without the need to reprocessing, ensure casting quality.
