Embodiment 1

[0054] Such as figure 1 As shown, the present embodiment is an open-form electromagnetic heating coil; wherein the electromagnetic heating coil and the internal and external protective layer are included, and a vertical coil is set on this electromagnetic heating coil (1), which), this position Through the center line of the coil, all longitudinal lengths of the coil, that is, the total length of the coil tube wall; there is a center line (6) on the cross section of the wire (3) in the position surface. The surface is interspersed in a location point (a), in which a vertical coil is transversely cross section line (b), such as image 3 As shown, through all of the cross section of the wire (3) in the coil; on the vertical line (B), one plane and the center line (6) of the wire (6) at an angle of 45 ° The separation is all wound around the wire in the coil, such as Figure 2A with Figure 2B As shown, the plane becomes a wire separated surface (2a) of the coil; at the position surface...

Embodiment 2

[0060] Such as figure 1 As shown, on the basis of the first embodiment, the compression separation device is further illustrated by the present embodiment, such as Figure 2A , Figure 2B As shown, at both sides of the electromagnetic heating coil opening surface (2), 4 sets of pressing surfaces (9a) of the opening face (9a) are longitudinally provided along the coil in the outer circle. The tensioning assembly (10) of the elastic pulley is provided; the structure of the pressure head includes the split structure (9), and the wedge-shaped tank (9b) is provided on the left side of the electromagnetic heating coil open surface. At the right side, the wedge-shaped hoe (9c) is provided, which constitutes a binding of the compression head and the split structure on the opening surface, and the tie structure penetrates all longitudinal lengths of the coil;

[0061] The soft material described in the inner protective layer is employed by industrial felt material, and the outer protective l...

Embodiment 3

[0068] On the basis of Example 1, if Figure 4 As shown, on the upper and lower sides of the electromagnetic heating coil opening surface (2), a hard electrical insulating material plate (11) is connected to the outer protective layer corresponding to the upper side of the opening surface, and corresponding to the lower side The inner side of the electrically insulating material (12) in the wire gap (C) is connected to a hard electrical insulating material plate (12), where the inner diameter of the inner diameter of the material is inner diameter in the wire; in the electrically insulating material plate (12 Make a screw hole, in the electrically insulating material plate (11), the outer protective layer, the electrically insulating material of the void (C) between the wires, and the through hole is treated with a plastic or metal screw (13). In the screw hole on the electrically insulating material plate (12), tighten, becoming a compression separation node on a hollow surface; a...

Abstract

The invention provides an opening and closing type electromagnetic heating coil. According to the opening and closing type electromagnetic heating coil, a separating inclined surface of a wire and a folding surface separated from inside to outside and located on inner and outer protective layers are arranged on the wire and the inner and outer protective layers of the electromagnetic heating coil to form an opening and closing surface for separating and combining the opening and closing type electromagnetic heating coil; the opening and closing surface penetrates through the whole longitudinal length of the coil; and a pressing and separating device for pressing a wire separating surface of the electromagnetic heating coil is arranged on the opening and closing surface, and separated wires in the coil are connected into a winding, so the opening and closing type electromagnetic heating coil is formed. Due to the opening and closing mode, the application range of the electromagnetic heating coil is greatly expanded; the electromagnetic heating coil can be used for heating, softening and extruding a connected steel bar connector which is a large-quantity wide-range high-quality connector used under a special working condition in a fabricated building; the electromagnetic heating coil can be applied to overlarge workpieces such as large tank bodies, especially field large-diameter oil and gas pipelines, the tank bodies or the pipelines need to be preheated before welding, and welding seams need to be subjected to tempering treatment after welding; and the opening and closing type electromagnetic heating coil is obvious in operation convenience.
