Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, the molding die structure of the special-shaped connecting pipe includes: connecting die 1, stripping plate 2, positioning plate 3, limit block 4, connecting punch 5; described connecting die 1, one end cross section of connecting punch 5 is Semi-circular, the cross section of the other end is square or semi-elliptical, and the two ends are connected in a conical shape; the positioning plate 3 is in the middle of the connecting die 1, and the limiting block 4 is in the square or semi-elliptical connecting die. Type one end. Take over die 1 and take over punch 5 are made of materials with better self-lubricating properties.

[0023] When in use, install the takeover punch 5 on the central slider of the press; the special-shaped takeover is divided into two symmetrical parts for blanking...

Abstract

The invention provides a stamping mold of a special-shaped connecting pipe, and relates to a machining method of the special-shaped connecting pipe in pressure container products. The defects that a traditional forging machining method is high in cost and long in manufacturing cycle are overcome. The stamping mold of the special-shaped connecting pipe structurally comprises a connecting pipe concave mold 1, a discharging plate 2, a positioning plate 3, a limiting block 4 and a connecting pipe convex mold 5. The cross section at one end of the connecting pipe concave mold 1 and the cross section at one end of the connecting pipe convex mold 5 are semicircular, the cross section at the other end of the connecting pipe concave mold 1 and the cross section at the other end of the connecting pipe convex mold 5 are square or semi-elliptic, and the two ends of the connecting pipe concave mold 1 and the two ends of the connecting pipe convex mold 5 are connected in a conical mode. The positioning plate 3 is placed in the middle of the connecting pipe concave mold 1, and the limiting block 4 is placed at the square end or the semi-elliptic end of the connecting pipe convex mold. The connecting pipe concave mold 1 and the connecting pipe convex mold 5 are made of materials with good self-lubrication performance. The stamping mold of the special-shaped connecting pipe can guarantee the hot stamping forming and demolding of the special-shaped connecting pipe easily, operation is convenient, mold universality is high, the applicable size range is wide, cost is greatly lowered, efficiency is improved, and all performance indexes can meet relevant standard requirements.

Description

technical field [0001] The invention relates to a processing method for a special-shaped connecting pipe in a pressure vessel product. Background technique [0002] At present, in oil refining chemical equipment, coal chemical equipment and other pressure vessels, special-shaped joints are often used to connect two parts of different shapes. Usually, the wall thickness of the special-shaped pipe is thick. One end of the structure is circular, and the other end is quadrilateral or elliptical. High, while the cost of forgings is high and the manufacturing cycle is long. Contents of the invention [0003] The technical problem solved by the present invention is to overcome the shortcomings of the above-mentioned traditional processing methods for special-shaped connecting pipes, improve efficiency and reduce costs. [0004] The invention provides a stamping die for a special-shaped connecting pipe, comprising: a connecting die 1, a discharge plate 2, a positioning plate 3,...
