Abstract

The invention relates to welding and can be used in development. the treatment of equipment for removal of the internal - abrasive on annular joints of pipelines, made by resistance welding. The purpose of the invention is to reduce the laboriousness during maintenance and increase reliability during operation — the injector 6 is attached to the driver of the longitudinal displacement 1, coaxially with the collector 4, and an annular puller 7 is fixed at the end of the fitting 6. In the process of moving, the cutting tool 5 cuts the burr, and the ring puller 7 removes the slag metal crust from the splash shield 4. This allows fully-mechanize the cleaning of the spray catcher and excludes a short circuit between the pipes being welded through the spray absorber during welding. 2 pe.

The invention relates to the welding of i can be used in the development of equipment for the removal of grating on ring-shaped pipes, pipelines, pipelines and so-called flash welding.

The purpose of the inventor is to reduce the labor intensity. When servicing the watt and the last reliability at

exploitation .

, Figure 1 shows a general view of the device at the time of the end of the butt welding; Figure 2 - the same, after cutting the burr and cleaning the spray bars.

The deburring device contains a longitudinal movement actuator 1, a rod 2 and a head 3, consisting of the extractor 4 and a cutting tool 5, the actuator is rigidly fixed to its body by a branch pipe 6, on which the stationary head spray is fixed. an annular joint 7 in which the end part facing the plane of the welded joint has a cutting edge and a shadow is placed on the splinter-catch along a sliding fit,.

The nozzle is installed - coaxially to the splash catcher to be equipped with a support with controlled alignment; removal- 1shk n spraying head of the cutting tool. Positions 9 and I O indicate welded pipes, 11 welders, 12 rollers of the roller table,

The device works as follows

The cutting tool 5 of the bar 2 is exposed coaxially to the roller of the roller conveyor, which are supplied by the floormakers. welding pipe 9 and 10 ,,

Actuator 1 and: welding machine 11 is provided with stops on the frame of the line, PS - switch drive and head in the npoifecce of device operation,

Putting 1-: and the butt joint when welding pipes does not change and choosing the bar length ensures the necessary position of the cutting tool 5 relative to the butt. In the plane of the butt the bushing head 4 is placed, and the head 3 is removed from the butt of the joint during the butt welding process. ,

After welding the joint by supplying liquid to the W of C; Ovugo cavity of hydraulic drive 1, head 3 is pulled through

weld joint. In the process of movement, the knives of the cutting tool 5 cut the burr, and the puller 7 finds the splinter 4 and the cutting part removes the metal and metal drops 13 from the outer surface of the splash guard while holding onto it.

The cut edge and particles of the C splash shield are removed from the internal surface of the pipeline with the cutting tool 5. The tool is removed from the pipes by moving the welded section along the rollers of the roller table 2 to the opposite direction from the pipe. The next pipe is fed to the vacant section with a section and welded to the previously welded section.

The preparatory deburring device allows you to fully mechanize the cleaning of the spray guard to heat the weld after each step, thereby significantly reducing the time spent on technical lunch and dinner.

In addition, regular ud.pette with the sprayer gshako-metal, peel-excludes a short NtbjKaHHe between the welded pipes through the sprayglass under the state of the art of O increases the operational reliability of the device ;.
