Technical Field

The invention relates to the technical field of beveling machines, in particular to a pipeline beveling machine.

Background

The bevelling machine functions to cut beveled edges on the edges of the pipe or sheet so that when two pipes or sheets are welded together they can be better joined together. The beveling machine uses different tool bits and profiles to accommodate different materials and machining requirements. The beveling machine has the characteristics of high efficiency, stability and accuracy, can greatly improve the welding efficiency and quality, and simultaneously reduces the problems and defects in the welding process. The welding method is widely applied to welding processing in industries such as petrochemical industry, shipbuilding, boiler manufacturing, pipeline engineering, electric power and the like. The existing pipeline beveling machine has some defects when in use.

When the flat plate fixing assembly is used for chamfering, the plate is clamped through the rubber roller and other structures, so that the chamfering tool bit stably moves forward, and the stability of the chamfering face of the ramp tool bit and the plate is effectively guaranteed. When adopting pipe fixed subassembly to carry out the groove, mutually supporting through joint subassembly isotructure for groove tool bit is fixed in one side of pipeline, and rotary device main part alright accomplish the groove work fast, and this process need not to apply external force to the device, makes the operation laborsaving more, simultaneously, and joint subassembly's radius of action can be adjusted, just so is applicable to the groove of different size pipelines, and the practicality is stronger. The beveling machine can be suitable for pipelines with different diameters, but in the process of beveling, the beveling angle cannot be quickly adjusted, the beveling work with different angles cannot be performed on a round pipe, the adjustable degree is low, and the simultaneous beveling of the inner wall and the outer wall of the pipeline cannot be performed, so that the machining efficiency is low. When the pipeline is subjected to groove processing, the two processing modes of the whole groove processing at the periphery of the pipe orifice and the local groove processing at the periphery of the pipe orifice cannot be switched.

The first electric push rod 201 continues to be extended when the adjusting block 203 is pushed to the limit position, the connecting block 208 pulls the sliding block 302 through the traction steel rope 304, so that the sliding block 302 is stored in the supporting block 206, the supporting assembly 2 can play a role in supporting the inner wall of the pipeline body 17 and limiting the rotation of the pipeline body 17, at the moment, the inner wall integral beveling or the outer wall partial beveling can be carried out under the state that the pipeline body 17 is kept fixed, the two processing modes of pipe orifice periphery integral beveling and pipe orifice periphery partial beveling can be switched, and the inner wall and the outer wall of the pipeline body 17 can be simultaneously beveled. The sealing plate 210 on the device can prevent metal scraps from falling into the device, and ensure the stable operation of the device.

As shown in fig. 1-3 and fig. 5-9, after the bevel machining mode is adjusted, the angle of the bevel is adjusted, because the fixed plate 603 above the third electric push rod 602 is fixedly connected with the top plate 5, a gap exists between the third electric push rod 602 and the first rotating sleeve 12 and the rotating block 601, and the sliding rod 604 below the third electric push rod 602 is connected with the connecting rod 606 through the bearing 605, when the bevel angle adjusting device is used, the cutter head 608 can be driven to rotate through the rotation of the rotating block 601 to perform bevel work, the third electric push rod 602 cannot be influenced, one side, close to the first rear plate 405, of the connecting rod 606 moves downwards or upwards through the extension or shortening of the third electric push rod 602, the ball shaft 607 rotates inside the cutter head 608, the cutter head 608 gradually tends to be horizontal or gradually tends to be vertical, and the bevel angle adjusting function is achieved. In operation, the first movable slot 609 ensures that the bit 608 rotates smoothly and the second movable slot 610 ensures that the connecting rod 606 moves or rotates smoothly. After the angle adjustment of the tool bit 608 is completed, the first synchronous wheel 9 is driven to rotate by the motor 8, the first synchronous wheel 9 drives the second synchronous wheel 11 to rotate by the synchronous belt 10, the second synchronous wheel 11 drives the first rotating sleeve 12 and the first bevel cutter 6 to rotate, the outside of the pipeline body 17 is beveled, the first gear 14 drives the second gear 15 to reversely rotate, and the rotating directions of the second rotating sleeve 16 and the second bevel cutter 7 are opposite to the rotating direction of the first bevel cutter 6, so that the device can simultaneously bevel the inner wall and the outer wall of the pipeline body 17. Finally, the position of the first rear plate 405 above the second rear plate 407 is adjusted through the second electric push rod 406, so that the distance between the supporting seat 1 and the top plate 5 is adjusted, the pipeline body 17 can be conveniently taken and placed by the device, when the baffle 402 is lifted, the opening 403 is gradually exposed, the follow-up blowing and collecting of chips on the surface of the supporting seat 1 are facilitated, and the supporting rod 404 can ensure that the first bevel cutter 6 and the second bevel cutter 7 can be stably supported.
