Special angle elbow manufacturing mold

Abstract

A special angle elbow manufacturing mold comprises an operation table, a fixed base is arranged on one side of the table top of the operation table, a hex bolt guide slot with angle graduated disk is arranged at the front part on the other side, and a pivot shaft hinged with an angle adjusting base is arranged at the rear part. A hex bolt movably connected with the operation table is arranged at the front part of the angle adjusting base. At the front parts of the fixed base and the angle adjusting base is arranged a screw fixation frame connecting a handle and a screw, and at the rear parts of the fixed base and the angle adjusting base is arranged an elbow fixed clamping plate. The other end of the screw is connected with an elbow movable clamping plate. In front of the elbow fixed clamping plate is arranged a limiting block with projection. A limiting plate with its curved surface in fit connection with the elbow is arranged between the fixed clamping plate and the limiting block, and forms a working pair together with the limiting block. The elbow is clamped and welded through the elbow movable clamping plate and the elbow fixed clamping plate. The limiting plate has an arc-shaped groove of different specifications and can be replaced. According to the invention, the welded elbow has the advantages of stable quality, high precision, and low manufacturing costs. In addition, the problem of shortage of elbow supply in market is solved and construction costs are lowered.

Description

technical field [0001] The invention relates to a mold for making parts, in particular to a mold for making special-angle elbows for making non-standard parts. Background technique [0002] The structure and function of modern buildings are becoming more and more complex, involving more and more specialties, and the complexity of pipelines in buildings is getting higher and higher. The area and direction of pipeline layout must not only meet the connection mode of the pipeline itself, but also meet the space requirements of the building. , It is often necessary to manufacture and install pipes with different arc directions. [0003] In the building structure with arc-shaped exterior and internal corridors, a large number of electromechanical pipelines are laid along the arc-shaped indoor corridors. Pipelines with DN<80 can adjust the direction through the cold simmering process or use conventional elbows to achieve the arc shape required by the design. Fire-fighting pip...

AI Technical Summary

Problems solved by technology

The fixed-angle elbows sold in the market cannot meet the design requirements; the special-angle elbows temporarily produced on site have a low pass rate; the factory makes molds to make elbows, and the total cost of mold opening and manufacturing is high
