Abstract

The invention relates to a method for manufacturing a family-use fire poker. Round steel is used as a raw material, is straighten through a machine, is put into a rolling machine and is rolled into the required shape for each part of the fire poker; a steel plate is punched into the shapes of the shoulders of the fire poker by a mould; the rolled fire poker arms, the fire poker and the fire poker shoulders are in butt connection through a butt-welding machine; and after the successful butt connection, the fire poker is subjected to straightening, lacquering and handle sleeving. The method has the advantages of small energy consumption, no environmental pollution and low labor intensity of workers; moreover, because all the processes are carried out at the room temperature, and the left shoulder and the right shoulder of the fire pokers have consistent thickness, the product has attractive appearance and long service life.

Description

A kind of preparation method of domestic tongs

Technical field

The present invention relates to a kind of preparation method of domestic tongs.

Background technology

The fire tongs of supplying family's use in the market is that forging and pressing form by high temperature, and have following shortcoming: 1. power consumption is high.Because it is red that the high temperature forging and pressing need smooth bar is burnt, this will consume a large amount of bituminous coal and cause energy waste.2. environmental pollution is big.The CO that in heating process, produces owing to bituminous coal combustion ₂, SO ₂The severe contamination atmosphere.3. the working environment of workers is abominable, labour intensity is big.High temperature and cause the workman to work under hot environment for a long time causes tremendous influence to workman's body and mind.4. technology is coarse, influences product appearance.Hammer into shape to beat and form because forging and pressing are pneumatic hammers one, this just causes product surface uneven, influences the product appearance quality.5. fire tongs left and right sides shoulder (fire tongs woman and son hang down folded part) became uneven has a strong impact on product service life.

Summary of the invention

The objective of the invention is to overcome the deficiency of above-mentioned prior art and a kind of environmentally safe, low power consuming made from new technology is provided, and the preparation method of the generous domestic tongs of good looking appearance.

The object of the present invention is achieved like this: 1. the waste and old round steel of workman is a raw material, by mechanical straightening.2. round steel is put into milling train and rolled into fire tongs each several part required form.3. with mould steel plate is struck out fire tongs shoulder shape.4. the fire tongs arm that rolls into, fire tongs handle are bumped by butt-welding machine with the fire tongs shoulder and connect.5. bumping fire tongs straightening, japanning, the cover handle that is connected into merit.Wherein the fire tongs shoulder is formed by two block-shaped identical steel plate spot welding.

The invention has the advantages that power consumption is few, environmentally safe, labor strength is low, and all technologies are carried out at normal temperatures, fire tongs left and right sides shoulder thickness unanimity, product design is attractive in appearance, and service time is long.

Fig. 1 is a structural representation of the present invention

The specific embodiment

As shown in Figure 1, embodiment 1:

1, the waste and old round steel of deciding diameter is put into the straightener straightening;

2, straightening is the good diameter round steel of deciding is put into milling train and is rolled into fire tongs arm (11) (21), fire tongs the shape of (13) (23);

3, straightening is the good diameter round steel of deciding is put into milling train and is rolled into fire tongs woman (1) fire tongs son (2)

Fire tongs woman's (1) making: A, will roll into fire tongs arm (11), fire tongs the length (36cm---85cm) that becomes to do fire tongs woman (1) under the steel bar of (13) shape.B, steel plate is put into mould strike out fire tongs shoulder (fire tongs lap) shape, then two block-shaped identical steel plates are welded into one with mash welder and make fire tongs shoulder (12).C, the fire tongs shoulder (12) that the fire tongs arm (11) of fixed length, fire tongs are welded into piece to (13) and point are placed on the butt-welding machine and weld.D, welding portion is polished with emery wheel, like this fire tongs woman.

Fire tongs son's (2) making: A, will roll into fire tongs arm, fire tongs the length (36cm---85cm) that becomes to do fire tongs son (2) under the steel bar of shape.B, will be the fire tongs arm of fixed length (steel bar that (21) shape is long is put into mould and is struck out and do the needed shape of fire tongs son (2).C, the fire tongs arm (21) that punching press is good are placed on (23) with fire tongs and weld D on the butt-welding machine, welding portion is polished with emery wheel.Like this, fire tongs son.

4, with mould the fire tongs shoulder (12) that is formed by two block plate spot welding of fire tongs woman (1) part is washed open a slit;

5, fire tongs son (2) is injected in the slit of fire tongs shoulder (12), flatten fire tongs shoulder (12) then;

6, in the positive centre-drilling hole of fire tongs shoulder (12), it is good to insert rivet (3) riveting then;

7, fire tongs woman (1) and fire tongs son (2) length that matched moulds is good is flushed;

8, stamp out the fire tongs face with the chess tool;

9, the fire tongs straightening;

10, fire tongs is curved semicircle with mould;

11, whole japannings except that the fire tongs handle;

12, with plastic bushing fire tongs is put (13) (23);

13, packing;

Embodiment 2:

Manufacture craft is with embodiment 1, and fire tongs woman (1) and fire tongs son (2) Len req are in embodiment 1 bracket.
