Metal mesh screen pipe pressing molding equipment

Abstract

The invention discloses metal mesh screen pipe pressing forming equipment. The mesh screen pipe pressing forming equipment comprises a workbench and at least three pressing forming mechanisms sequentially arranged on the workbench, each pressing forming mechanism comprises two sets of supporting mechanisms which are symmetrically arranged, an upper rolling wheel, a lower rolling wheel, transmission gears and a driving mechanism, the upper rolling wheel and the lower rolling wheel are rotationally arranged between the two sets of supporting mechanisms through a rotating shaft wheel, the upper rolling wheel is arranged above the lower rolling wheel in a stacking mode, a circular channel is formed between the upper rolling wheel and the lower rolling wheel, the transmission gears are arrangedon rotating shafts of the upper rolling wheel and the lower rolling wheel respectively, the driving mechanism is arranged on the workbench, and the driving mechanism is utilized to drive the lower rolling wheel or the upper rolling wheel to rotate so as to synchronously drive the upper rolling wheel or the lower rolling wheel to rotate. An outer pipe and an inner pipe of a screen pipe are fully compacted and cannot be easily separated through extrusion of the multi-stage pressing molding equipment; a U-shaped support and an adjusting pressing plate form a sliding groove, the adjusting pressing plate is of a detachable structure, the situation of jamming during replacement of the upper rolling wheel and the lower rolling wheel is prevented, and therefore workers can carry out replacement on the upper rolling wheel or the lower rolling wheel conveniently.

Description

technical field [0001] The invention relates to a metal mesh screen tube pressing and forming equipment. Background technique [0002] In oil and natural gas extraction operations, screens play a very important role, and solid-liquid, solid-gas separation is achieved through screen filtration. According to the international standard ISO 17825 and my country's petroleum industry standard SY6916, screens are generally divided into four types: wire-wound screens, pre-filled screens, metal mesh screens, and punched screens. At present, the screen tubes produced by our company are filter screen tubes which are combined with metal mesh screen tubes and punched slotted screen tubes, namely: punched slotted inner tube, supporting metal mesh, filtering metal mesh, outer tube, and the overall screen tube is used to pull the base pipe for the upper and lower wells. After welding can be done. [0003] The processing sequence of this screen tube is: welding the inner tube and the outer...

AI Technical Summary

Problems solved by technology

[0004] The rolling equipment currently used is facing difficulties in installation and post-commissioning, poor rolling forming, and a small range of rolling sizes. In view of the defects of the existing technology, a new type of metal mesh screen tube compression forming is urgently needed in the market. Equipment to ensure the beauty of the screen after rolling and the convenience during operation
