Hydraulic pipe cutter

Abstract

The invention discloses a hydraulic pipe cutter which comprises a cutter head, a hydraulic cutting bracket, a pneumatic positioning chuck, a feeding mechanism, a deburring mechanism and a pressure detection system, wherein the hydraulic cutting bracket adopts a multi-stage hydraulic telescopic pole; a cutting table is arranged at the bottom of the hydraulic cutting bracket; a hydraulic cylinder and a pneumatic cylinder, which are connected with the multi-stage hydraulic telescopic pole, are arranged at the bottom of the cutting table; and the cutter head is fixedly hung at the top of the hydraulic cutting bracket. The device structure is simple, and the equipment cost is low; a vertical up-down cutting way is adopted, and the cutting is performed by self gravity of the cutter head; a pressure sensor and a display facilitate reducing negative effects in the cutting process; by the adoption of a travel switch and a feeding pneumatic chuck, error accumulation caused by complicated transmission links is avoided, and the machining precision is improved; and after cutting is completed, the deburring mechanism is used for polishing a fracture to reduce the subsequent manufacturing procedure.

Problems solved by technology

[0002] With the development and progress of industry, steel pipe has become an indispensable important product and raw material in industrial production, and is widely used in petroleum, chemical, electric power, natural gas, metallurgy, shipbuilding, boiler, pharmaceutical, water treatment and other industries, as well as pipeline installation of new projects Engineering, pipeline maintenance and other related technical fields, there are many related equipment for steel pipe cutting in the prior art, such as planetary cutting machine, hydraulic cutting machine, external card cutting machine, numerical control hydraulic cutting machine, electric cutting machine, pneumatic cutting machine Machines, etc., hydraulic cutting equipment is the most widely used, but the cutting equipment related to the existing technology generally has the following technical problems, 1) the overall structure is complex, the operation is troublesome, and the clamping is unstable; 2) the scope of use is narrow and can only be used for Cutting one or two steel pipes greatly limits the scope of use of the cutting device, and the feeding accuracy is low; 3) Most of the existing cutting equipment is only simple cutting, and the groove cannot be processed, so that the incision is prone to deformation, and the incision is not smooth. Clean, poor finish
