CN105127691A - Manufacturing technique of cooking pot with bilateral structure - Google Patents

Abstract

The invention relates to a manufacturing technique of a cooking pot with a bilateral structure, belonging to the field of cooking utensils. The technical scheme is as follows: selecting a high-quality steel plate as a raw material, processing the high-quality steel plate into a needed round plate by adopting a blanking machine; carrying out drawing forming on the round plate; carrying out rounding treatment on the product obtained by drawing forming; carrying out crimping on the obtained semi-finished product, and carrying out treatment by adopting an edging machine; carrying out rolling on the upper opening of the product by adopting a rolling machine; punching to form a spoon handle hole and pot lug holes; treating the surface of the product by adopting a polishing machine, and then carrying out nitriding treatment by adopting gas; and finally mounting auxiliary parts. Compared with the prior art, the manufacturing technique has the advantages that the product manufactured according to the manufacturing technique is attractive in appearance and sanitary, the cooking pot is high in solidness, a spoon after nitriding treatment is completely black and bright, and can not get rusty, thus being more durable.

Description

There is the production technology of the cooking pot tool of bilateral structure

Technical field

The present invention relates to a kind of production technology with the cooking pot tool of bilateral structure, belong to cooking apparatus field.

Background technology

Along with improving constantly of people's living standard, people are also more and more higher for the performance requirement of kitchen utensils, and the outside of frying pan of the prior art, saucepan arranges that what adopt is crimping is more, the single-side structural of extension skirt materials or carry out thickening process to pan itself and reach the requirement of reinforcing pot body.The condition that such process reaches in use still is easier to occur breakage because colliding with.

Summary of the invention

In view of the problems referred to above existing in prior art, the present invention proposes a kind of production technology with the cooking pot tool of bilateral structure.

The present invention adopts following technical scheme:

A. the cold-rolled steel sheet of high-quality is selected to be that raw material off-chip is machined to required disk;

B. drawing die is contained on stretcher, by disk drawing and forming;

C. with circle-cutting machine, circle of contact process is carried out to edge on the product of drawing and forming;

D. round semi-finished product crimping again will be cut, edging machining process;

E. with sealing machine, roll forming is carried out to the suitable for reading of product again;

F. perforating mold is contained on punch press, goes out spoon hole, handle hole;

G. surface treatment: after innner and outer polishing being carried out to product with sanding machine, then carry out gas nitriding process;

H. last, carry out perfect to product, install appurtenances.

The present invention compared with prior art has the following advantages: bilateral structure avoids the accumulation of pan outward flange oil stain, profile is more attractive in appearance, health, make the robustness of pan stronger simultaneously, more meet the requirement that people are economical and practical, and the spoon body after gas nitriding process leads to black shinny, non-corrosive is more durable in use.

Further, preferred version is:

The thickness of quality steel plate selected in step a is 1.5 to 2 millimeters.

Detailed description of the invention

Embodiment 1:

Have a production technology for the cooking pot tool (frying pan) of bilateral structure, its concrete production technology is as follows:

The cold-rolled steel sheet of high-quality (thickness is 1.75 millimeters) is selected to be machined to the disk of 40 required cm for raw material off-chip.

Drawing die is contained on stretcher, and by disk drawing and forming, the bottom of a pan of pot body is on a horizontal plane, and the diameter of bottom of pot body circumference is about 16cm, and pot wall is curved-surface structure.

With circle-cutting machine, circle of contact process is carried out to edge on the product of drawing and forming, make Qi Guobi contour.

To cut round semi-finished product crimping again, after crimping, pot wall (inner side) is upper along be highly 9cm apart from the bottom of a pan (upper plane), on be 32cm along the diameter of inside circumference, edging machine is processed crimping and is processed.

Carry out rolling with sealing machine to the suitable for reading of product again, the bilateral upper and lower distance after rolling is 8 millimeter, and inside and outside the bilateral part of pot body, lateral extent is 3.4 millimeter.

Perforating mold is contained on punch press, goes out 3 spoon holes, three hole line figures be equilateral triangle you, arrange in inverted triangle, pitch of holes ultimate range is 3.5cm, and minimum range is 2cm inverted triangle base on pot body along being highly 2.5cm.

Surface treatment: after innner and outer polishing being carried out to product with sanding machine, then carry out gas nitriding process.

Finally, carry out perfect to product, install hingle.

Embodiment 2

Have a production technology for the cooking pot tool (saucepan) of bilateral structure, its concrete production technology is as follows:

The cold-rolled steel sheet of high-quality (thickness is 2 millimeters) is selected to be machined to the disk of 50 required cm for raw material off-chip.

Drawing die is contained on stretcher, and by disk drawing and forming, the bottom of a pan of its pot of body is on a horizontal horizontal plane, and the diameter of bottom of pot body circumference is 17.5cm pot wall is curved-surface structure.

With circle-cutting machine, circle of contact process is carried out to edge on the product of drawing and forming, make Qi Guobi contour.

To round semi-finished product crimping again be cut, after crimping on pot wall along being 13cm apart from pan bottom height, on be 36cm along the diameter of inside circumference, edging machine is to crimping processing process.

Carry out roll forming with sealing machine to the suitable for reading of product again, the bilateral upper and lower distance after rolling is 8 millimeter; Inside and outside the bilateral part of pot body, lateral extent is 4 millimeter.

Be contained in by perforating mold on punch press, go out two pairs of handle holes, symmetrical index, pitch of holes is 10cm, and holes line is highly 3cm apart from edge on pot body.

Surface treatment: after innner and outer polishing being carried out to product with sanding machine, then carry out gas nitriding process.

Finally, carry out perfect to product, install handle.
