[0002] The heating tube is made by putting electric heating wire into a seamless metal tube (carbon steel tube, titanium tube, stainless steel tube and copper tube), filling the gap with magnesium oxide powder with good thermal conductivity and insulation, and then shrinking the tube, and then processing it into various shapes required by users. It has simple structure, high thermal efficiency, good mechanical strength and good adaptability to harsh environment. It can be used for heating various liquids and acids, alkalis and salts, and is also suitable for heating and melting metals with low melting points (lead, zinc, tin and babbitt alloy).

During use, the existing bending device cannot adjust the spacing between the two sets of bending support components used to support the electric heating tubes, and cannot meet the requirements of bending processing of electric heating tubes with different curvatures. Moreover, the bending support group used to support the electric heating tubes cannot limit and clamp the electric heating tubes, and cannot improve the stability of the bending device during the folding and assembly processing of the electric heating tubes.

[0004] Based on this, the present invention designs a bending device for processing electric heating tubes to solve the above-mentioned problems. Summary of the invention

[0009] Based on the above technical features, the present invention adopts an arm rod and a connecting screw installed on one side of the movable slider, and a connecting screw hole is opened through the middle of the metal sleeve. Since the connecting screw hole matches the connecting screw structure, the bending frame can be threadedly fixed to one side of the limiting guide, and the force-applying component can also disassemble, connect, repair and replace the limiting guide and the bending frame according to the usage. The anti-slip clamping plates are respectively installed at both ends of the metal sleeve, and the clamping spring is installed between the anti-slip clamping plates and the circular baffle. The heating tube body that needs to be bent can be clamped and limited between the two sets of bending support components, so as to avoid shaking of the heating tube body during the bending process.

[0010] In this solution, an electric push rod is installed in the middle part of the outer side of the first baffle plate. By controlling the electric push rod to extend or retract, the limit guide member limited in the guide slot can be moved and adjusted. When the two groups of limit guide members are synchronously adjusted for displacement in relative or opposite directions, the equipment can adjust the distance between the two groups of bending support assemblies according to the requirements of bending processing of the heating tube body with different curvatures. In conjunction with the hydraulic cylinder installed in the middle part of the top of the second baffle plate, the electric push rod can be started to perform a pushing action, so that the heating tube body mounted between the two groups of limit guide members can be bent.
