Example Embodiment

[0017] Such as figure 1 with figure 2 As shown, the frame 1 of the steel plate butt welding machine has a horizontal guide rail 11 and a driving screw 12 passing through the guide rail 11. A slider 21 is provided on the horizontal guide 11, and the slider 21 can be driven by the driving screw 12 Slide along the horizontal rail 11. The bracket 2 of the automatic butt weld grinding device is generally L-shaped, and its longitudinal arm is fixedly connected with the slider 21 by bolts, and its transverse arm carries other parts of the butt weld automatic grinding device. In this way, the automatic grinding device It can move back and forth along the guide rail 11 on the butt welding machine with the slider 21 to realize the automatic grinding operation of the steel plate workpiece 8 placed on the automatic welding table of the original steel plate butt welding machine. Of course, the bracket 2 can also be integrated with the slider 21, or the bracket 2 is directly slidably connecte...

Abstract

The invention relates to an automatic coping device for butt welding seams. The device is characterized in that the automatic coping device for the butt welding seams is arranged on a steel plate butt welding machine by a bracket and is movably connected with a horizontal guide rail and a horizontal transmission screw mandrel of the steel plate butt welding machine; on the bracket, a main driving abrasive belt wheel and a lower abrasive belt wheel strain the abrasive belt together which is moderately pressed on the butt welding seam, and the main driving abrasive belt wheel drives the abrasive belt to cope the butt welding seam. Through the improvement, components of the original steel plate butt welding machine can be effectively used for arranging the seam coping device on the original steel plate butt welding machine, thus realizing automatic coping of the butt welding seam on an automatic welding worktable of the original steel plate butt welding machine.

Description

technical field [0001] The invention relates to a welding seam grinding device, in particular to an automatic grinding device for butt welding seams of plates in the production process of spiral steel pipes. Background technique [0002] In the production process of the spiral steel pipe, the tail end of the previous steel coil and the front end of the next steel coil need to be butt welded by welding, so that a straight butt weld is formed. The butt weld has a certain reinforcement relative to the plates of the front and rear coils, usually between 2.5 and 4.0 mm. If the necessary grinding treatment is not carried out on the butt weld, it will have a negative impact on subsequent production and even affect product quality. The traditional grinding method is to manually use an angle grinder for grinding. Due to manual operation, the quality of grinding is not easy to control. If the workers operate a little improperly, the grinding wheel will damage the plate and affect th...
