Drilling and chamfering integrated device for steel pipe machining

Abstract

The invention discloses a drilling and chamfering integrated device for steel pipe machining. The device comprises a knife holder and an inner ring sleeve. The lower end of the inner ring sleeve is provided with a drill bit through a fixed base, a hollow column and multiple insulation cylinders are fixedly mounted between the fixed base and the knife holder, a conductive bar is connected between the hollow column and each insulation cylinder, a pressurizing mechanism is arranged in each insulation cylinder, multiple knife returning boxes are symmetrically mounted on the side wall of the innerring sleeve, reset mechanisms are arranged in the knife returning boxes, an electromagnetic valve is arranged between each knife returning box and the corresponding insulation cylinder, and the side wall, away from the hollow column, of each knife returning box is slidingly provided with a chamfering knife in a penetrating manner. The device can be used for a drilling and chamfering device for conventional steel pipe machining to be used, in the chamfering process, according to actual machining needs, chamfering knives of different specifications can be rapidly replaced, knife retreating, replacing, aligning and other tedious operation are not needed, and the machining precision and the machining efficiency are further improved.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing devices, in particular to an integrated drilling and chamfering device for steel pipe processing. Background technique [0002] With the acceleration of the industrialization process, steel production and steel processing and manufacturing technologies have become more and more mature. Steel pipes are a common rigid material processing product. At present, steel pipes have a wide range of uses in many fields of industry. As a force carrier, steel pipes It can be used for the construction of the frame. As a protective support device, the steel pipe can be used for the protection of the outer tube of the cable or other objects. For different fields, the steel pipe also needs to be processed in a targeted manner. The processing steps of the steel pipe generally include: polishing, drilling, and chamfering. , pipe expansion, etc. [0003] The existing steel pipe processing equipment is ...
