Abstract

The utility model relates to a cold stamping mould comprising an upper mould 1 and a lower mould 2 which are matched with each other. The working surface of the upper mould 1 is in a semicircular convex shape with one side provided with an opening, and the working surface of the lower mould 2 is in a semicircular concave shape with the one side provided with an opening; the mounting and connecting end of the upper mould 1 and the lower mould 2 is in a platy structure provided with a mounting hole 5, the other end of the same is in a cylindrical structure with one side provided with an opening, and the end surface of the mounting and connecting end is in a semicircular fit working surface. The utility model has rapid processing speed and high efficiency and reduces the labor intensity and the processing cost, and the moulded leak stoppage tenon reaches or meets the standard requirement.

Description

A kind of cold punching die

One, technical field:

The utility model relates to pipeline perforation leak stopping clamp machining machine and tool, particularly a kind of pipeline perforation leak stopping clamp cold punching die.

Two, background technology:

Petroleum system profit pipeline has all used for many years at present, most of well water amount all reaches more than 95%, water quality is outstanding day by day to the extent of corrosion of pipeline, the perforation phenomenon is serious, originally adopt same specification pipe fitting cutting certain size both sides to add the weldering otic placode when the leak stopping clamp, there is time-consuming, complex process in this processing mode, product quality is low, efficient is low, organization of production is difficult, bad formation series.

Three, summary of the invention:

The purpose of this utility model provides a kind of improved pipeline perforation leak stopping clamp cold punching die, it can be avoided effectively and overcome shortcoming or the deficiency that exists in the prior art, make the leak stopping clamp of moulding reach or meet standard-required, raise the efficiency, reduce labour intensity and processing cost.

Cold punching die described in the utility model comprises patrix (1) and counterdie (2).Described patrix (1) and counterdie (2) match, and the working face of its cooperation is to be open and clear mouthful semicircle convex (3) on one side, and the working face of its cooperation of described counterdie (2) is that one side is open and clear mouthful semicircle spill (4).

Wherein, the installation link of described patrix (1) and counterdie (2) is for having the platy structure of installing hole (5), Yi Bian the other end is the cylindrical-shaped structure (6) that is provided with vertical gap, its end face is semicircle cooperating face.

The utility model has following advantage and beneficial effect compared with prior art:

1, plate cold punching once-forming, arc size is reasonable, is better than the clamp of the weldering otic placode of pipe fitting cutting

2, operating efficiency improves

3, convenient to operation at the scene

Four, description of drawings

Fig. 1 is a structural representation;

Wherein: patrix (1), counterdie (2), the protruding pressure body of semicircle (3), the recessed pressure body of semicircle (4), installing hole (5), cylindrical-shaped structure (6)

Fig. 2 is following mode structure vertical view

Five, the specific embodiment

With reference to Fig. 1-Fig. 2, a kind of improved pipeline perforation leak stopping clamp cold punching die comprises patrix 1 and counterdie 2.Patrix 1 and counterdie 2 match, and the working face of its cooperation is to be open and clear mouthful the protruding pressure body 3 of semicircle on one side, and the working face of described counterdie 2 its cooperations is that one side is open and clear mouthful the recessed pressure body 4 of semicircle.

The installation link of patrix 1 and counterdie 2 is the platy structure that has installing hole 5, Yi Bian the other end is the cylindrical-shaped structure 6 that is provided with vertical gap, its end face is semicircle cooperating face.

During use, patrix 1 is connected with hydraulic head, counterdie 2 fixes with the hydraulic press working face, processed clamp stock is placed on the recessed pressure body 4 of semicircle of counterdie 2, the wall thickness according to the different size pipeline has calculated size, adopt the steel plate of identical wall thickness, the driving hydraulic press is descending, makes the pressurization that cooperatively interacts of the semicircle cooperating plane of patrix 1 and counterdie 2, and the clamp stock of desire processing is the punching press once-forming just.

Claims

1, a kind of cold punching die, comprise patrix (1) and counterdie (2), it is characterized in that described patrix (1) and counterdie (2) match, the working face of its cooperation is to be open and clear mouthful semicircle convex (3) on one side, and the working face of its cooperation of described counterdie (2) is that one side is open and clear mouthful semicircle spill (4).

2, cold punching die according to claim 1, the installation link that it is characterized in that described patrix (1) and counterdie (2) is for having the platy structure of installing hole (5), the other end is for being provided with the cylindrical-shaped structure (6) of vertical gap on one side, and its end face is semicircle cooperating face.
