Grinding machine for tube strip weld joint

Abstract

The invention provides a grinding machine for a tube strip weld joint, which smoothly grinds an external surface and has low cost at the same time. The grinding machine comprises an abrasive belt, two wobble wheels and a swinging mechanism, wherein the abrasive belt rotates under the driving of a power wheel to grind the tube strip weld joint, the power wheel is arranged on a machine body, the two wobble wheels are arranged on a swinging plate, the abrasive belt rounds the power wheel and the two wobble wheels, the swinging plate is rotatably connected to the machine body through a swinging shaft, the swinging shaft is located in a vertical-mid-plane of the two wobble wheels, and the swinging mechanism drives the swinging plate to swing in a reciprocating way around the swinging shaft.

Description

technical field [0001] The invention relates to a tube blank weld seam grinder for grinding the weld seam of a tube blank, in particular to a weld seam grinder for grinding the outer surface weld seam during on-line production of stainless steel welded pipes (wires). Background technique [0002] With the development of welded pipe technology, the surface quality of welded pipes also needs to be continuously improved. Weld seam grinding has become an indispensable link. Now most of the domestic welded pipe unit manufacturers follow the example of Taiwan, and their grinding links are divided into four groups. Arranged in order; the grinding device used is a throwing wheel 1, the grinding device can be adjusted up and down, front and rear according to needs, so as to achieve the treatment effect of the weld 3 of the steel pipe (tube blank) 2, but this grinding device is only in the form of " Point method" to contact the tube blank, that is, the throwing wheel contacts the tube...

Problems solved by technology

[0002] With the development of welded pipe technology, the surface quality of welded pipes also needs to be continuously improved. Weld seam grinding has become an indispensable link. Now most of the domestic welded pipe unit manufacturers follow the example of Taiwan, and their grinding links are divided into four groups. Arranged in order; the grinding device used is a throwing wheel 1, and the grinding device can be adjusted up and down, front and rear according to needs, so as to achieve the treatment effect of the weld 3 of the steel pipe (tube blank) 2, but this grinding device is only in the form of " Point method" to contact the tube blank, that is, the throwing wheel contacts the tube blank with a "point" during grinding (see figure 1 , 2 ), the surface of the tube blank is not smooth after being polished and the hand feel is poor, which directly affects the product quality in severe cases

What's more, if the consumption of raw materials is large when the thick-walled pipe is polished
