Abstract

The male die brazing structure comprises a male die body, wherein an insert sleeve is connected to the lower portion of the outer surface of the male die body through welding, bearing platforms are arranged at two ends of a contact surface of the insert sleeve and the male die body, and fillers are filled in the bearing platforms. The utility model overcomes prior art's is not enough, reasonable in design cooperatees with the terrace die bulk phase through inlaying the cover to burn the filler of copper in inlaying the cushion cap at cover both ends, make the terrace die life-span show the promotion, avoided terrace die fracture phenomenon, practiced thrift the cost of material again, and great shortening precision finishing's time.

Description

Terrace die copper brazing structure

Technical Field

The utility model relates to the technical field of molds, especially, relate to a terrace die copper brazing structure.

Background

The male die is a part which is mainly used for forming the inner surface of a product in the die, namely a part taking the shape as a working surface.

However, as shown in fig. 2, the existing male die component is made of tungsten steel, so that when the male die component is used, the male die component is often broken due to the effect of stripping and drawing force after the component is stretched. And the cost of adopting the structural material is higher, and the processing of parts with larger processing allowance according to the structure is also more difficult.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art, the utility model provides a terrace die copper brazing structure has overcome the not enough of prior art, reasonable in design, and is cooperateed with the terrace die bulk phase through inlaying the cover to burn into the filler of copper in inlaying the cushion cap at cover both ends, make the terrace die life-span show and promote, avoided terrace die fracture phenomenon, practiced thrift the cost of material again, and great shortening precision finishing's time.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:

the male die brazing structure comprises a male die body, wherein an insert sleeve is connected to the lower portion of the outer surface of the male die body through welding, bearing platforms are arranged at two ends of a contact surface of the insert sleeve and the male die body, and fillers are filled in the bearing platforms.

Preferably, the inner diameter of the insert is matched with that of the punch body, and the outer diameter of the insert is provided with grinding allowance.

Preferably, the filler is copper, and the filler is burnt into the bearing platform at high temperature.

Preferably, the punch body is made of tungsten steel.

The embodiment of the utility model provides a terrace die copper welded structure. The method has the following beneficial effects: the embedding sleeve is matched with the male die main body, and copper fillers are burnt into the bearing platforms at the two ends of the embedding sleeve, so that the service life of the male die is obviously prolonged, the phenomenon of breakage of the male die is avoided, the cost of materials is saved, and the time of precision machining is greatly shortened.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention.

The utility model provides a terrace die copper welded structure, includes terrace die main part 1, it has inlayed cover 2 to connect through the welding below terrace die main part 1 surface, inlay cover 2 and terrace die main part 1 contact surface both ends and all seted up cushion cap 3, the intussuseption of cushion cap 3 is filled with filler 4.

The inner diameter of the insert sleeve 2 is matched with that of the male die body 1, and grinding allowance is reserved on the outer diameter of the insert sleeve 2.

The filler 4 is copper, and the filler 4 is burnt into the bearing platform 3 at a high temperature.

The male die body 1 is made of tungsten steel.

During production and processing, the male die body 1 and the insert sleeve 2 are processed, grinding allowance is reserved on the outer diameter of the insert sleeve 2, the inner diameter of the insert sleeve is matched with that of the male die body 1, two ends of the insert sleeve 2 are processed into bearing platforms 3, copper is burnt into the bearing platforms 3, then the male die body 1 and the insert sleeve 2 are welded through brazing, after a part is cooled, the end of the male die part is used for positioning, and the outer diameter of the grinding insert sleeve 2 ensures the concentricity of the part.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
