Description

The process that a kind of energy-efficient cooker is made

Technical field

The invention belongs to the daily cooking utensil field, specially refer to the process that a kind of energy-efficient cooker is made.

Background technology

The energy-efficient cooker that puts goods on the market, finding is few, although can in numerous data, see the shape of relevant this class cooker, the report of structure, but how to produce excellent energy-saving cooker product better, with minimum cost of investment, the qualified products that technological process the most easily, the most reliable process go to obtain to be amenable to but are the difficult problems of producing extensively, and also do not find relevant report always.In the disclosure of numerous relevant energy-saving cookers; the report that also has only structure; and there is not the description of preparation method; the patent report of the most close relevant structural defence; just mentioned on the utility model patent as far back as 85 years by managing to increase structure and the principle that the bottom surface heat exchange area improves the thermal efficiency; as CN85201777U energy-saving cooker and CN85204721U fast energy-saving cooker; these two pieces of patents have all been reported some heat absorption fins have been set on cooker drain pan face in addition; also can realize with casting all-in-one-piece way; to obtain energy-conservation effect; but do not relate to concrete manufacture craft and method program etc.; do not go again to overcome such as strengthening weight; bodily form clumsiness; drawbacks such as profile is not attractive in appearance, and can't popularize.And for example the patent No. is the CN98246152.6 Cooking vessel with fins, also discloses a kind of a plurality of quoits with different-diameter, sheet as ring muscle and heat absorption fin, and is connected as a single entity at the bottom of the cooker, reaches energy-saving effect.But how this class energy-saving cooker goes to realize repeatability produce, use which type of processing step just to go bail for, never appear in the newspapers to reach the qualified bulk article of performance.Through consulting, in fact, there be not manufacture craft, method and the program of the complete science of a cover, can't under economically viable prerequisite, produce product attractive in appearance, practical, efficient energy-saving, cause thus never having by a large amount of present situations of popularizing on the market so far.In order to make energy-conservation service of goods family, service society, promote environmental protection and reduce the wasting of resources and environmental pollution, the inventor is in being engaged in exploitation to this type of energy-saving cooker, manufacturing process, also be on the basis of a large amount of technological experiments, explore one the cover exercisable, can save the easy operation of cost, can repeatedly obtain the qualified technological process of product parameters again.As cooker, be the daily product that the numerous common people be unable to do without, it is low how to satisfy cost, and product safety is reliably durable in use, is aim of the present invention.

Summary of the invention

The technical issues that need to address of the present invention, be at not comparatively system, complete process for making in the prior art, realize the production of energy-efficient cooker, product can be had produce in batches and have desirable qualification rate, therefore need to seek kind of a reasonable method step.

Purpose of the present invention just provides the process that a kind of energy-efficient cooker is made, and the present invention seeks to finish by the following technical solutions, and the process that a kind of energy-efficient cooker is made is carried out according to following step:

1. the making of heat absorption fin, heat absorption post and bracing ring:

A. selecting thickness is aluminium sheet or the corrosion resistant plate of 0.2mm-6mm, by different length, width, highly shear, punching press, and bend to (different length suitable configuration-can not use delphic words) heat absorption fin;

B. select aluminium sheet or corrosion resistant plate to make hollow or solid cylindricality heat absorption post;

C. select the aluminium sheet or the corrosion resistant plate of similar thickness, be made into the bracing ring suitable with diameter at the bottom of the cooker;

2. on the assembling mould of special use, arrange, locate, install.

3. select a welding manner: can adopt soldering, argon arc welding, ratio-frequency welding;

B scolder and solder flux: can select aluminium base scolder, ferroalloy scolder for use;

4. utilize under the scolder melt temperature, will absorb heat fin, heat absorption post, bracing ring and cooker bottom surface of assembling mould to weld;

5. the demoulding;

6. the welder of institute part is soaked in acid solution, make welding slag softening, loose;

7. adopt the pressure-air blasting craft, unnecessary welding slag is removed, polish again; Simultaneously to the cleaning of the inner face at the bottom of cooker polishing.

8. surface treatment is carried out in the cooker bottom, cover the thick enamel class material of one deck 0.01-0.5mm in its bottom.

9. inspection process, a overall aesthetic degree, b has or not rosin joint and sheet, the c tensile test.

Described heat absorption fin is made and is shaped, be with the heat absorption fin shear strike out length for length, vice-minister, in, lack different specifications, as a specific embodiment, its heat absorption fin can bend to waveform respectively again for 1 times, 0.8 times, 0.6 times, 0.3 times of cooker bottom radius.

The different welding manners of described selection can be by the appointed condition difference, and product size, shape, weight, material difference are selected multiple Type of Welding such as soldering, argon arc welding, ratio-frequency welding.The corresponding required also difference of temperature scope that adds.The employing soldering welding preferably of this product, during soldering, when adopting aluminium base scolder, aluminium matter is absorbed heat, backing material, and heated perimeter should be 400 ℃-700 ℃; During with the ferroalloy scolder, when adopting stainless steel heat absorption backing material, heated perimeter should be 400 ℃-1500 ℃.Describedly soak in acid solution, can adopt 50% dilute hydrochloric acid solution, normal temperature soaked 0.5-4 hour down, was as the criterion with the welding slag loose easy blasting treatment that becomes, and the height of time with the concentration of the cheap acid solution of taking changes.

The invention has the beneficial effects as follows, use this process for making, duplication of production goes out energy-efficient cooker in batches, and products made thereby is economized material, saved time, and is heated evenly at the bottom of the cooker, and heating is fast, heat energy utilization rate height, and also attractive in appearance, practical.The product percent defective that this method is produced is low, and the product test result is more energy-conservation more than 30% than like product.
