Description

Technical Field

[0001] The utility model belongs to the field of welding heat treatment, and particularly relates to a cross-shaped quick plug and a plug part for zone heating in welding heat treatment. Background Art

[0002] When conducting welding heat treatment, the output cable of the temperature control cabinet is connected to the heating device (heating rope or heating sheet) using a copper plug. Usually, for ease of on-site assembly, copper plugs are used in pairs. A pair of copper plugs generally consists of a cylindrical end and a columnar end. During use, the copper plugs are respectively installed at the cable end and the heating device end for supporting use. When both are cylindrical ends or both are columnar ends simultaneously, they cannot be used, and only one-to-one single-line connection can be made, and a one-to-many parallel circuit connection cannot be formed.

[0003] Several drawbacks have been summarized in production practice:

[0004] ① During production, the heating device often needs to temporarily replace the connector due to mismatched joint ports, or all cylindrical ends become ineffective due to the lack of columnar ends.

[0005] ② The copper plug is only suitable for single-line connection and cannot meet the requirement when a large number of parallel circuits are needed for the zone heating precise temperature control method.

[0006] Since the wiring at the heat treatment work site is temporarily determined by the structure and environment of the component to be heat treated, the on-site temporary layout time is very limited. Therefore, when the above problems occur, the copper plug usually needs to be replaced or the cable line needs to be re-arranged at the production site, and the time consumed accounts for more than 50% of the entire welding heat treatment operation, seriously affecting production efficiency. Summary of the Invention

[0007] The purpose of the utility model is to provide a cross-shaped quick plug and a plug part for zone heating in welding heat treatment. The present application provides a copper cross-shaped quick plug, which can meet the requirement of on-site quick plug and avoid the problems of re-replacing the plug and re-arranging the parallel circuit. It solves the problem that when the existing copper plug for welding heat treatment is respectively installed at the cable end and the heating device end for supporting use, it cannot be used when both are cylindrical ends or both are columnar ends simultaneously, and only one-to-one single-line connection can be made, and a one-to-many parallel circuit connection cannot be formed.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] The cross-shaped quick plug for zone heating in welding heat treatment provided by the utility model includes a copper cross-shaped joint body, and two cylindrical end plugs and two columnar end plugs are symmetrically arranged at the four ends of the copper cross-shaped joint body respectively.

[0010] Preferably, a hemispherical boss is provided on the inner side of the cylindrical end plug.

[0011] Preferably, a locking groove extending spirally is formed on the outer side wall of the columnar end plug, and the locking groove is circumferentially arranged along the arc-shaped outer side wall of the columnar end plug starting from the platform.

[0012] Preferably, the depth of the locking groove gradually decreases from the starting end to the ending end.

[0013] Preferably, an adjusting gap for the columnar end plug is formed at the central axis of the columnar end plug, and the adjusting gap for the columnar end plug is arranged along the axial direction of the columnar end plug.

[0014] Preferably, the outer surface of the copper cross-shaped joint body is coated with an insulating rubber shell.

[0015] Preferably, a hemispherical boss is provided on the inner side of the cylindrical end plug; a locking groove extending spirally is formed on the outer side wall of the columnar end plug, and the locking groove is circumferentially arranged along the arc-shaped outer side wall of the columnar end plug starting from the platform; the hemispherical boss is matched with the locking groove.

[0016] Preferably, the depth of the locking groove gradually decreases from the starting end to the ending end.

[0017] Preferably, the outer surface of the copper cross-shaped joint body is coated with an insulating rubber shell.

[0018] A cross-shaped quick plug for sectional heating in welding heat treatment, comprising at least two connected cross-shaped quick plugs, each cross-shaped quick plug comprising a copper cross-shaped joint body, and two cylindrical end plugs and two columnar end plugs are symmetrically arranged at the four ends of the copper cross-shaped joint body respectively.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] The cross-shaped quick plug for sectional heating in welding heat treatment provided by the present utility model has two cylindrical end plugs and two columnar end plugs symmetrically arranged at the four ends of the cross-shaped quick plug. When performing welding heat treatment, when it is for the cylindrical end or the columnar end at the same time, there is no need to replace the joint, or all the cylindrical ends or columnar ends will not fail due to the lack of columnar ends or cylindrical ends; at the same time, two cylindrical end plugs and two columnar end plugs are symmetrically arranged on the cross-shaped joint, which can be used for multi-path parallel connection, or more connection ports can be formed after connecting the cross-shaped quick plugs to each other, solving the problem of parallel circuit arrangement during sectional heating and precise temperature control of large and complex structural components.

[0021] Furthermore, the cross-shaped quick plug is provided with a mechanical locking structure, specifically a hemispherical boss inside the female head and a circumferential locking groove on the male head. The circumferential locking groove starts from the plane of the male connector and extends helically in the circumferential direction, gradually becoming shallower. When in use, the hemispherical boss is used in combination with the locking groove, and the connector is locked when rotated due to the gradually shallowing groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Working process of this application:

[0047] The copper cross quick plug is used to connect the cable end and the heating device end, acting as a conversion joint.

[0048] When parallel connection is required, the copper cross quick plug is used between the cable main line and the parallel line to quickly arrange the parallel line; when there are many parallel lines, multiple copper cross quick plugs can be connected side by side (the cross connector becomes a swastika connector) and then connected to the line.

[0049] At the same time, when in use, the hemispherical boss is matched with the locking groove, and the joint is locked as the groove gradually becomes shallower during rotation.

The locking groove 2 is circumferentially arranged along the arc outer side wall of the columnar end plug starting from the platform 4; the groove depth of the locking groove 2 gradually becomes smaller from the starting end to the ending end. This facilitates the passage of the cylindrical end boss during locking, and the locking joint is achieved as the groove gradually becomes shallower during rotation.

[0055] A columnar end plug adjustment gap 5 is provided at the central axis of the columnar end plug 3. The columnar end plug adjustment gap 5 is located at the center of the plug 3 to provide a margin for thermal expansion and contraction of the metal and prevent the joint from getting stuck during use.
