Steel tube cutting seam expanding and flattening integrated machine

Abstract

The invention discloses a steel tube cutting seam expanding and flattening integrated machine. The steel tube cutting seam expanding and flattening integrated machine comprises a hydraulic station, a pushing part, a notching part, an expanding part and a flattening part; the hydraulic station, the pushing part, the notching part, the expanding part and the flattening part are arranged in sequence from left to right; the notching part consists of a circular disc shearing device, sliding blocks and a supporting frame; an upper cutter blade and a lower cutter blade of the circular disc shearing device are two cutter blades with different diameters; the upper cutter blade is mounted in the middle of an upper cutter shaft; the lower cutter blade is fixed to a lower cutter seat; the upper cutter shaft are fixed to the sliding blocks on the two sides through bearings; the left sliding block and the upper sliding block respectively slide in supporting frames on the two sides; an adjustment lead screw is arranged on the upper side of each supporting frame to control the pressing-down amount of the upper cutter blade; the lower cutter seat and the expanding part are connected integrally. After the circular disc shearing device is adopted, the workshop working environment is greatly improved; flue gas pollution is avoided; in addition, the overall production machining is completed continuously and integrally; the labour is saved; the efficiency is improved; good economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of steel pipe production and processing, in particular to an integrated machine for cutting, opening, and flattening steel pipes. Background technique [0002] In recent years, the rapid development of my country's equipment manufacturing industry has driven the growth of steel production and sales, especially steel pipes. With the increase in the amount of steel pipes used by steel production and processing enterprises, the number of substandard products produced is also increasing exponentially. In order to tap the utilization value of waste and inferior products and improve the utilization rate of resources, general steel production and processing enterprises will cut, expand, and press unqualified products into flat plates to make other products, so that the raw materials can get the maximum utilization value and achieve "transformation". The purpose of turning waste into treasure". [0003] The curren...

Problems solved by technology

However, the plasma cutting machine will produce a large amount of toxic gas and metal dust during the cutting process, which will not only pollute the ecological environment, but also cause harm to the health of the operators; in addition, the steel pipe will be moved to the expansion and flattening machine after plasma cutting Processing, the entire production and processing process cannot maintain continuity, resulting in low efficiency and high cost
