Abstract
The invention discloses a ceramic heating core and manufacturing method of electric soldering iron, which contains heating core base with cone cylinder shape, wherein the base material is La1-xMxCrO3 (M is bivalent alkaline earth element; x=0.001-0.15).The manufacturing method comprises the following steps: adopting La1-xMxCrO3 powder as base material and 5-50%wt paraffin as binder; blending La1-xMxCrO3 powder and paraffin evenly; toasting; squeezing to mould prismatic or column blank for at least five times; sintering the blank; manufacturing the blank into pyramid or frustum of a cone shape.
Description
[technical field]
The present invention relates to a kind of electric iron with ceramic heating core and working method.
[background technology]
The most structure of existing heat generating core is the form of exothermic material with the wire for being matrix with the pottery.Generally be to be made by following several technologies: resistance silk material such as tungsten filament, molybdenum filament constant resistance silk material are wound in definite shape, are placed in the mould, ceramics powder (being generally aluminum oxide powder) is added in the mould, the sintering of heating again forms.Perhaps the resistance silk material is adopted typography, be compressed on the unsintered ceramic substrate, be rolled into cylinder shape again, the sintering of heating forms.Outside surface all covers ceramic layer to play the insulating effect.Also having a kind of heat generating core is exactly the United States Patent (USP) 4544829 disclosed PTC materials that are used for the electric iron heat generating core, and it is shaped as flats.
The shortcoming of product existence at present shows following several aspect:
The production of current heating core is owing to be subjected to the restriction of manufacture craft can't be made into the product that the heating end concentrates on head and is shaped as the tip, and the heating end is generally the plane, and end diameter is greater than 2mm.This just causes the temperature end defective far away apart from the working end point of welding head, after using pure tin on request, under the prerequisite that does not influence working efficiency and quality, high temperature dot should move forward more than the 10mm to the tip, this just causes the phenomenon of electric iron bulk temperature superelevation, and the electric iron life-span sharply descends.Because the temperature of heating core improves, also shorten the work-ing life of heating core. after welding temperature improved, vulcanized inadequately at the tip of product, has increased the work waiting time, has reduced production efficiency.
[summary of the invention]
The objective of the invention is provides a kind of head for most advanced and sophisticated in order to overcome above-mentioned the deficiencies in the prior art, and the heating end concentrates on the tip, can shorten the distance of temperature end and electric iron working point, long service life, the high electric iron of working temperature is with ceramic heating core and working method.
Ceramic heating core of the present invention comprises the heating core matrix, it is characterized in that: the heating core matrix be shaped as the awl column, the material of matrix is La
