Description

A kind of four-way of solid forging processing

Technical field

This utility model relates to the four-way of a kind of solid forging processing.

Background technology

During pressure piping gas collection, pipe interior is lost by medium, under fluid dynamics factor effect, produces tight The erosion damage of weight, existing four-way is low due to intensity, therefore the most easily bores a hole under the erosion damage of high-pressure fluid medium, lets out , therefore there is serious potential safety hazard in leakage and the accident of cracking.

So we need a kind of new moulding technique, solve problem above.

Summary of the invention

The purpose of this utility model is the four-way providing a kind of solid forging to process, it is possible to improve what prior art existed Problem, it is provided that a kind of existing four-way of effective solution is easy under the washing away of high-pressure fluid medium bores a hole, leak and CRACKING ACCIDENT Forming technique.

This utility model is achieved through the following technical solutions:

The four-way of a kind of solid forging processing, including body and be arranged on 2 through holes inside described body and form four Logical structure, the body at 2 described through hole two ends is respectively arranged with plumb joint, and described plumb joint and described body are whole Body forging forms.

The four-way pipe being processed to form due to casting uses too metal to water in progressive die tool, processes through cooled and solidified, cleaning Rear formation gradually, can produce a large amount of dust, harmful gas and sound pollution in the course of processing, and, the four of casting processing generation The internal defect that can exist due to casting technique itself of siphunculus, causes wherein existing the defect such as bubble, crack, uses it for height Pressure pipeline uses, and easily concentrates due to partial structurtes stress and produces perforation, particularly there is bubble, location of cracks, and it is resistance to Pressure ability, when using as high-voltage tube, easily easily produces leakage and CRACKING ACCIDENT, in this utility model, uses forging work Skill overall processing forms body construction, it is possible to the as cast condition eliminating metal is loosened so that it is mechanical performance is far above casting four formed Siphunculus.

Further, for this utility model is better achieved, described body is cube structure.

Further, for this utility model is better achieved, 2 described through holes lay respectively at described body in opposite directions In the middle part of two groups of end faces.

Further, for this utility model is better achieved, the respectively boring of described through hole gets out.

Further, for this utility model is better achieved, described body and described plumb joint are that rustless steel is made.

The processing method that the invention also discloses the four-way of a kind of solid forging processing, comprises the following steps:

S1: rustless steel forging is become hexahedron structure and forms body and 2 assembly welding joints, makes 2 assembly welding joints position respectively In body two groups of end face geometric centers in opposite directions；

S2: utilize rig to be provided with between two groups of end faces of plumb joint 2 through holes of brill at body, form four-way knot Structure.

Body construction is used Forging Technology to be processed to form by this utility model, reduces the bubble produced in Metal Forming Process And crack, it is possible to it is effectively improved its comprcssive strength so that it is there is more preferable shock resistance, when using for pressure piping, Can have longer service life.

This utility model compared with prior art, has the advantages that

The back of this utility model solid forging four-way is bigger, and shock resistance and corrosion resistant ability have obtained greatly carrying Height, is therefore greatly improved, also reduces potential safety hazard simultaneously the service life of four-way.

Accompanying drawing explanation

In order to be illustrated more clearly that the technical scheme of this utility model embodiment, will use required in embodiment below Accompanying drawing be briefly described, it will be appreciated that the following drawings illustrate only some embodiment of the present utility model, the most should be by Regard the restriction to scope as, for those of ordinary skill in the art, on the premise of not paying creative work, also may be used To obtain other relevant accompanying drawings according to these accompanying drawings.

Detailed description of the invention

Below in conjunction with specific embodiment, this utility model is described in further detail, but embodiment party of the present utility model Formula is not limited to this.

As shown in Figure 1, 2, existing four-way pipe structure mainly carries out molding formation by mould, owing to using process In, by the pressure of tube fluid, on the way A1, A2 position stress is concentrated very much, the most in use makes A1, A2 in figure Position produces perforation and cracking, and then the accident that is easily caused occurs.

As shown in Figure 3,4, the four-way of a kind of solid forging processing, including body 101 and be arranged in described body 101 2 through holes 102 of side form four-way structure, and the body 101 at 2 described through hole 102 two ends is respectively arranged with plumb joint 103, described plumb joint 103 forms for solid forging with described body 101.

This utility model utilizes the body of solid forging and plumb joint structure to form agent structure, utilizes rig to get out Two through holes so that it is form four-way structure, owing to, in forging process, the space existed between the metal of body construction sets in forging Gradually decreasing under standby pressure and even disappear, make the space between metal less, it is pressure, resistance to corrosion is higher, it is not easy to produce Raw perforation, the problem of leakage.

Embodiment 1:

In the present embodiment, process for convenience, it is preferable that described body 101 is cube structure.Utilize forging equipment Forging forms body construction, and on body, forging forms plumb joint, makes two assembly welding joints lay respectively at square two in opposite directions On individual end face, easy to process, and, quality is more prone to control.

In the present embodiment, in order to make overall structure in use, its subjected to stress is more uniform, it is preferable that 2 Described through hole 102 lays respectively in the middle part of described body 101 two groups of end faces in opposite directions.

By two through holes being separately positioned on middle part, it is possible to make the distribution of through hole outboard structure more uniform, make body Back is evenly distributed so that it is during by fluid matasomatism, be more uniformly stressed, it is not easy to impaired.

Embodiment 2:

In the present embodiment, it is preferable that described through hole 102 respectively boring gets out.Body construction is used with plumb joint After Forging Technology solid forging molding, rig is utilized to get out through-hole structure respectively on body two end faces in opposite directions, Form it into the semi-finished product structure of four-way, it can be carried out surface process again so that it is antiseptic power is more preferable.

In order to make it have more preferable antiseptic property, in the present embodiment, it is preferable that described body 101 and described weldering Joint 103 is made for rustless steel.

Embodiment 3:

The processing method disclosing the four-way of a kind of solid forging processing in the present embodiment, comprises the following steps:

Compared with common four-way, the four-way structure that this utility model is processed to form, overall area of stress concentration (A1 ', A2 ') bigger, it is not easy to bore a hole, leak and CRACKING ACCIDENT.

Owing to overall structure back (A1 ', A2 ') is bigger, thus its shock resistance, corrosion resistant ability have obtained greatly carrying Height, when thus be accordingly used in pressure piping use, is greatly improved, also reduces safety the most hidden simultaneously the service life of four-way Suffer from.

The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this For the technical staff in field, this utility model can have various modifications and variations.All in spirit of the present utility model and principle Within, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
