Problems solved by technology

Due to the certain elastic stress of the specially made steel plate, there are always mismatches when butt welding on the pipeline. Although it is welded together by knocking hoops, the welded anti-piercing pipe is irregular and does not fit tightly with the pipeline. There are bulges in many places, which do not meet the basic standards of pipelines and affect the promotion and use

Embodiment Construction

[0010] In order to further disclose the technical solutions of the present invention, the following will be described in detail through examples in conjunction with the accompanying drawings:

[0011] When applying the present invention, the female mold body 1 is connected on the piston rod of the molding machine, the male mold body 6 is installed on the molding workpiece platform, so that the two mold bodies correspond up and down, the positioning pin holes 2 correspond to the positioning pins 7, and the anti- Put the special steel plate through the pipe, and the special steel plate that conforms to the outer area of ​​the buckle pipeline is placed horizontally on the surface of the male mold body, start the molding machine, the female mold body 1 goes down, buckles on the special steel plate, and cooperates with the male mold body 6, A circular arc-shaped anti-piercing pipe with an arc-shaped rib can be pressed out. During the construction, the two arc-shaped anti-piercing p...

Abstract

The invention discloses a compacting tool set for a penetration-proof tube. The compact tool set comprises a male die body and a female die body; the female die body and the male die body are designed to be semi-circular; the radius of the female die body is greater than that of the male die body; circular arc grooves for eliminating elastic stress are uniformly formed in the inner arc-shaped surface of the female die body; two mutually symmetrical positioning pin holes are formed in two ends of the inner arc-shaped surface respectively; a support is axially arranged at the middle part of the outer arc-shaped surface of the female die body; a flat plate-type connecting seat is welded on the support, and bolt holes are arranged at the four angles of the connecting seat; arc-shaped cogs matched with the circular arc grooves formed in the inner arc-shaped surface of the female die body are uniformly arranged on the outer arc-shaped surface of the male die body; cylindrical positioning pins matched with the positioning pin holes in the inner arc-shaped surface of the female die body are arranged at the two ends of the outer arc-shaped surface of the male die body; a support is axially arranged at the middle part of the section of the male die body; a flat plate-type connecting seat is welded on the support and bolt holes are arranged at the four angles of the connecting seat; the connecting seat of the female die body is connected with the piston of a mould press; and the connecting seat of the male die body is connected with the workpiece platform of the mould press. The compacting tool set, provided by the invention, solves the problem of penetration-proof tube pressing and elastic stress eliminating; and the two parts of the penetration-proof tube pressed can be buckled in an anastomotic manner, so that the penetration-proof tube can be tightly fit with the pipeline which is protected by the penetration-proof tube, the welding procedure is convenient, and the construction efficiency is significantly improved.

Description

1. Technical field [0001] The invention relates to a pressing mold for an anti-piercing pipe to prevent criminals from drilling holes in oil pipelines, gas pipelines and water pipelines to steal oil, gas and water in oil fields, and solves the problem of interlocking and welding of anti-piercing pipes and oil-gas-water pipelines. matching problem. 2. Background technology [0002] At present, in order to prevent criminals from stealing oil, gas and water, oil, gas and water pipelines are welded with a layer of anti-piercing pipes that cannot be moved by electric drills or hacksaws. arc welded. Due to the certain elastic stress of the specially made steel plate, there are always mismatches when butt welding on the pipeline. Although it is welded together by knocking hoops, the welded anti-piercing pipe is irregular and does not fit tightly with the pipeline. There are bulges in many places, which do not meet the basic standards of pipelines and affect the promotion and use....
