Composite pipe inner weld grinding machine

Abstract

The invention discloses a sharpening machine for a composite pipe internal weld joint. The sharpening machine comprises a sharpening feeding mechanism, a metal pipe servo mechanism and a blocking wheel installing base. The sharpening feeding mechanism is arranged above the metal pipe servo mechanism, and the blocking wheel installing base is installed on the surface of the metal pipe servo mechanism and located in front of the sharpening feeding mechanism. The sharpening feeding mechanism comprises a feeding mechanism body, a sharpening head lifting fine tuning mechanism, a shaping support arranged in front of the feeding mechanism body and a tool setting component arranged on one side of the shaping support. The feeding mechanism body is installed at the top of the sharpening head lifting fine tuning mechanism which is arranged above the metal pipe servo mechanism. Sharpening finish machining is performed on the internal weld joint, and the problem that in the process of performing manual tool setting and sharpening on a composite pipe, the efficiency is low is solved. The sharpening efficiency is improved, the sharpening precision of the composite pipe is improved, and the qualified rate of the composite pipe is increased in the sharpening process.

Description

technical field [0001] The invention relates to a grinding machine, in particular to a grinding machine for welding seam inside a composite pipe. Background technique [0002] Composite pipes are generally two layers, in which a corrosion-resistant metal pipe is placed inside the other metal pipe, and the two are fixed into one structure by expansion and end welding. [0003] After the two metal pipes are welded, part of the welded part needs to be turned off, and a certain step is left; the step needs to be manually ground at the welded part to meet the installation requirements of the pipe fittings. [0004] Due to the low accuracy of manual grinding, it is easy to scratch the inner liner. After scratching the inner liner, it needs to be re-welded and re-grinded, which affects the efficiency of the finished product. Moreover, the cost of manual grinding is high, the grinding precision is low, and the grinding time is long; manual grinding is dangerous, and the pass rate o...

Problems solved by technology

[0004] Due to the low accuracy of manual grinding, it is easy to scratch the inner liner. After scratching the inner liner, it needs to be re-welded and re-grinded, which affects the efficiency of the finished product.

Moreover, the cost of manual grinding is high, the grinding precision is low, and the grinding time is long; manual grinding is dangerous, and the pass rate of the composite pipe after grinding is low. If the inspection fails, it needs to be re-grinded, which affects the efficiency of the product leaving the factory.
