Abstract
The invention relates to the technical field of production of T iron and discloses a diameter-expanding technique for T iron produced through cold forging. The diameter-expanding technique comprises the following steps: S1) cutting a to-be-processed material, thereby forming a columnar billet; S2) performing diameter-reducing processing on the columnar billet by using a diameter-expanding mould while forming a tapered structure by the columnar billet, wherein the tapered structure comprises a first end part, a second end part and an arc-shaped connecting part for connecting the first end part with the second end part, and the diameter of the first end part is greater than the diameter of the second end part; S3) shaping the tapered structure after the diameter-reducing processing, thereby forming T iron end products. According to the invention, the diameter-expanding mould is used for performing diameter-expanding processing on the columnar billet, the tapered structure is formed, and the tapered structure comprises the first end part with the larger diameter, the second end part with the smaller diameter and the arc-shaped connecting part for connecting the first end part with the second end part, so that the billet is prevented from being broken during a forming process. According to the invention, the production cost is greatly lowered and the production efficiency is increased.
Description
Technical field
The present invention relates to the production technical field of T iron, more particularly, particularly a kind of cold forging is produced the swollen footpath technique of T iron.
Background technology
T iron also claims magnetic core, is the important spare part in the electrical equipment such as television set, and T iron need to adopt T swage tool to process.Due to existing T iron have two kinds more special, the first is that material is heavy heavier, length of material is longer, and the second is that material weight is lighter, length of material is shorter, because these two kinds of products can not adopt T iron Mould Machining at present, can only process by the method for Vehicle Processing, the shortcoming of its existence is: increased greatly production cost, reduced production efficiency simultaneously.Therefore, be necessary to design a kind of novel material that is applicable to and weigh production technology light and the T iron product that length of material is shorter.
Summary of the invention
The object of the present invention is to provide a kind of cold forging to produce the swollen footpath technique of T iron, this technique has advantages of that reduced production cost has also improved production efficiency simultaneously.
In order to achieve the above object, the technical solution used in the present invention is as follows:
Cold forging is produced a swollen footpath technique for T iron, comprises the following steps,
S1, material to be processed is carried out to blank step, form column Bear-grudge material;
S2, the step that adopts swollen footpath mould to carry out tube reducing processing to column Bear-grudge material, in this process, column Bear-grudge material forms a pyramidal structure, this pyramidal structure comprises the arc connecting portion of first end, the second end and connection first end and the second end, and the diameter of described first end is greater than the diameter of described the second end;
S3, the step that the pyramidal structure after tube reducing processing is carried out to moulding, form T iron finished product.
Preferably, described swollen footpath mould comprises swollen footpath mould, be located at the first swollen footpath nib and the second swollen footpath nib that in the mould of swollen footpath, are communicated with, the diameter of described the first swollen footpath nib is greater than the diameter of the second swollen footpath nib, and the junction of described the first swollen footpath nib and the second swollen footpath nib is arc linkage section.
Preferably, the diameter of described first end is less than the diameter of T iron finished product head.
Compared with prior art, the invention has the advantages that: the present invention adopts swollen footpath mould to carry out the processing of swollen footpath to column Bear-grudge material, form pyramidal structure, and pyramidal structure comprises the first end that diameter is larger, the second end and the arc connecting portion that is connected first end and the second end that diameter is less, arc connecting portion has avoided causing fractureing of Bear-grudge material when moulding; Simultaneously swollen footpath of the present invention technique has better plasticity with respect to upsetting, and there will not be crackle during tube reducing, has reduced greatly production cost and has also improved production efficiency simultaneously.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be described in further detail.
Consult shown in Fig. 1 and Fig. 2, a kind of cold forging provided by the invention is produced the swollen footpath technique of T iron, comprise the following steps,
The first step, material to be processed is carried out to blank step, form column Bear-grudge material, as shown in Figure 2 a;
Second step, the step that adopts swollen footpath mould to carry out tube reducing processing to column Bear-grudge material, in this process, column Bear-grudge material forms a pyramidal structure, this pyramidal structure comprises first end 1, the second end 2 and is connected the arc connecting portion 3 of first end 1 and the second end 2, and the diameter of described first end 1 is greater than the diameter of described the second end 2, as shown in Figure 2 b;
The 3rd step, the step that the pyramidal structure after tube reducing processing is carried out to moulding, form T iron finished product, as shown in Figure 2 c.
Consult shown in Fig. 3, for the swollen footpath mould adopting in the present invention, it comprises swollen footpath mould 4, be located at first swollen footpath nib the 5 and second swollen footpath nib 6 of swollen footpath mould 4 interior connections, the diameter of described the first swollen footpath nib is greater than the diameter of the second swollen footpath nib, and the junction of described first swollen footpath nib the 5 and second swollen footpath nib 6 is arc linkage section 7.
In forming process, the diameter of described first end 1 is less than the diameter of T iron finished product head, and the diameter of general first end 1 is less than the diameter 0.3MM of T iron finished product head, to facilitate, puts mould into; Above-mentioned arc connecting portion 3 is mainly used for preventing folding material T iron product in lower one moulding process.
Although described by reference to the accompanying drawings working of an invention mode; but the patent owner can make various distortion or modification within the scope of the appended claims; as long as be no more than the described protection domain of claim of the present invention, all should be within protection scope of the present invention.
