Steel-plastic composite pipe heating device

Abstract

The invention relates to the field of steel-plastic composite pipe machining equipment, in particular to a steel-plastic composite pipe heating device. A heating assembly and two symmetrically-arranged clamping assemblies are included. The heating assembly comprises a lower heating plate and an upper heating plate arranged on the top of the lower heating plate. Four supporting legs are arranged atthe bottom of the lower heating plate. The inner side wall of each of the upper heating plate and the lower heating plate is provided with two installing grooves. Each installing groove is internallyprovided with a heating pipe. The two clamping assemblies are the same in structure and each comprises a bearing frame, a rotation component and a clamping component. The steel-plastic composite pipeheating device has the beneficial effects that the two clamping assemblies can be used for clamping the two ends of an inner pipe, hand holding through manual hand operation is not needed, and the labor intensity of workers is lowered; and through the rotation components, the inner pipe of a plastic composite pipe can be rotated, the inner piper can slowly rotate, and the situation that due to uneven heating of the inner pipe, bonding with a steel wire gauze is poor is avoided.

Description

technical field [0001] The invention relates to the field of steel-plastic composite pipe processing equipment, in particular to a steel-plastic composite pipe heating device. Background technique [0002] The steel-plastic composite pipe is a galvanized internal plastic-coated composite steel pipe for water supply made by pretreatment, preheating, internal coating, leveling, and post-treatment processes. At present, steel-plastic composite pipes are mostly produced by winding steel wires on the inner pipe. After the steel mesh is formed, the adhesive is coated, and then the outer layer is compounded, that is, the production method of the outer pipe. This method needs to heat the inner pipe to make the steel mesh and the inner pipe bond together. The traditional heating method of the inner pipe is It is a manual hand-held clamp to clamp the inner tube and heat the inner tube. The manual heating method is time-consuming and labor-intensive. Working for a long time will bring ...

[0002] The steel-plastic composite pipe is a galvanized internal plastic-coated composite steel pipe for water supply made by pretreatment, preheating, internal coating, leveling, and post-treatment processes. At present, steel-plastic composite pipes are mostly produced by winding steel wires on the inner pipe. After the steel mesh is formed, the adhesive is coated, and then the outer layer is compounded, that is, the production method of the outer pipe. This method needs to heat the inner pipe to make the steel mesh and the inner pipe bond together. The traditional heating method of the inner pipe is It is a manual hand-held clamp to clamp the inner tube and heat the inner tube. The manual heating method is time-consuming and labor-intensive. Working for a long time will bring greater labor intensity to the worker. In addition, this heating method is made by the worker. The tube is fixed to heat the inner tube, which will lead to uneven heating, local overheating of the inner tube, and poor adhesion between the inner tube and the steel wire mesh
