Device for simultaneously grinding inner walls and outer walls of steel pipes

Abstract

The invention discloses a device for simultaneously grinding the inner walls and the outer walls of steel pipes. The device comprises a workbench, a support, a collecting tank, a clamping mechanism, an outer grinding mechanism and an inner grinding mechanism; the support is arranged at the upper end of the workbench, and the clamping mechanism is arranged at the left end of the inner side of the support and comprises a clamping plate, a rotating motor, an annular gear, a gear, electric telescopic rods, supporting plates, rubber pads and springs; the outer grinding mechanism is installed at thelower end of a moving block; and the inner grinding mechanism is arranged under the outer grinding mechanism and comprises an inner grinding wheel, a threaded rod B, a fixing sleeve, a threaded sleeve, a second sliding groove, an electric hydraulic cylinder, a drive gear, a driven gear A, a driven gear B, a rectangular block and a connecting rod. The device is novel in design, simple in structure, capable of simultaneously grinding the inner walls and the outer walls of steel pipes with different thicknesses, high in grinding efficiency, wide in application range, capable of effectively preventing impurities such as scrap iron from polluting the environment, high in practicality and worthy of popularization.

Description

technical field [0001] The invention relates to a grinding device, in particular to a simultaneous grinding device for inner and outer walls of a steel pipe. Background technique [0002] The development of steel pipe production technology began with the rise of the bicycle manufacturing industry, the development of petroleum in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after the Second World War, and the chemical industry. The development of industry, as well as the drilling and transportation of oil and gas, have all vigorously promoted the development of the steel pipe industry in terms of variety, output and quality. [0003] The steel pipe is used to transfer fluid and powder, exchange heat and produce mechanical parts and containers, what's more it's a kind of economical steel. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can ...

AI Technical Summary

Problems solved by technology

Among them, the rust removal treatment on the surface of the steel pipe directly affects whether the steel pipe can be firmly combined with the anti-corrosion layer, thereby affecting the anti-corrosion life of the steel pipe

Most of the existing steel pipe grinding processes are done by hand-held grinding machines. Manual grinding requires experience. If the operation is not good, the surface of the steel pipe will be uneven and waste will easily be formed. The method of hand-held sandpaper grinding and derusting is time-consuming, laborious and inefficient. , the general mechanical grinding method also has low grinding efficiency. At the same time, the iron filings generated during the grinding process are scattered around, which is difficult to handle and pollutes the environment. Grinding, can not be processed at the same time, the grinding efficiency is low
