Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] Such as Figure 3 to Figure 12 As shown, the manufacturing system of the large-diameter steel-plastic winding pipe flange of the present invention includes plasticizing extrusion equipment, a rotating power mechanism 50, a positioning mechanism 20, a pressure roller mechanism 30, a cooling device output pipe 33 and a bracket 60.

[0041] The plasticizing extrusion equipment includes an extruder 10 and a die 40 connected to the extrusion end of the extruder 10 . The extruder 10 plasticizes and melts the solid plastic particles, and extrudes them through the die 40 to form a melt sheet with a certain width and thickness.

[0042] Die 40 is known in the art. Such as Figure 5 to Figure 7 As shown, the mold 40 includes an upper mold 41 and a lower mold 42 that cooperate with each other. The upper mold 41 includes a mold cavity 411 , and the lower ...

Abstract

The invention discloses a system for manufacturing a large-caliber steel-plastic winding pipe flange. The system comprises plastifying extrusion equipment, a rotary power mechanism, a positioning mechanism, a compression roller mechanism, a cooling device output pipe and a bracket, wherein the plastifying extrusion equipment extrudes melt sheets by an extruder by virtue of a mold; the rotary power mechanism is opposite to the positioning mechanism and can be respectively connected with two ends of a steel-plastic winding pipe of a to-be-manufactured flange in a matched mode; the bracket is positioned between the rotary power mechanism and the positioning mechanism; the positioning mechanism is positioned at the extrusion end of the plastifying extrusion equipment; and the mold of the plastifying extrusion equipment is positioned nearby a pipeline supporting and positioning flange of the positioning mechanism and is positioned at a melt sheet position coated with the manufactured winding pipe flange. According to the extruded melt sheets and a coating and rolling process, the large-caliber steel-plastic winding pipe flange is manufactured, and the defect that the large-caliber steel-plastic winding pipe flange cannot be manufactured by adopting a traditional injection molding method is overcome; and moreover, a lift adjusting device is adopted by the rotary power mechanism and the positioning mechanism, the manufacturing requirements of the steel-plastic winding pipe flanges of different specifications are met, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a system for manufacturing large-diameter steel-plastic winding pipe flanges Background technique [0002] The connection of steel-plastic winding pipes has always been a difficult point in the construction of steel-plastic winding pipelines. Small-diameter steel-plastic winding pipes are usually connected by clamp-type elastic sealing. For large-diameter steel-plastic winding pipes (especially steel-plastic winding pipes with a diameter above DN2000), the construction operation is complicated and the construction speed is slow by using clamp-type elastic sealing connections. Therefore, in the prior art, large-diameter steel-plastic winding pipes are usually connected by electric melting tape. However, there are the following defects in the connection of electric hot melt belt: (1) electric hot melt has very strict requirements on the construction environment, and it cannot be operated with electricity in a humid or water envi...
