Description
Technical Field
The invention relates to a beveling machine for bent pipes, in particular to a beveling machine for bent pipes with an internal boring function for automatic welding.
Background
With the increase of oil and gas pipeline construction year by year, the automatic pipeline welding technology is more reliable than the manual welding technology, and the welding quality is better, and the welding efficiency is higher. However, automated welding techniques are generally applicable to welding between line pipes and line pipes, and are not applicable to welding between straight pipes and bent pipes. This is because in the return bend course of working, the return bend outer arc side can attenuate, so the return bend wall thickness is generally thicker than the line pipe in the actual processing, and the return bend pipe end generally adopts interior transition mode, because the return bend side is the slope form behind the interior transition, is unfavorable for automatic weld robot to creep.
In order to ensure that the automatic welding robot can smoothly carry out welding, the inner bore hole of the elbow needs to be turned, and the inner wall of the elbow is thinned to the wall thickness of the line pipe. However, the conventional pipe bending beveling machine can only process an outer bevel and an inner transition bevel due to functional defects, and the function of inner boring cannot be realized. The inventor shows that the defect of large wall thickness deviation of the machined inner bore hole part is mainly caused by the following reasons:
(1) shaking the workpiece;
(2) the pipe end of the bent pipe has a certain ovality;
(3) the tailstock cannot be placed horizontally.

Detailed Description
Hereinafter, the elbow beveling machine with an inside boring function for automatic welding according to the present invention will be described in detail with reference to the accompanying drawings and exemplary embodiments.
The invention provides a bent pipe beveling machine with an internal boring function for automatic welding.
In an exemplary embodiment of the invention, as shown in fig. 1, the pipe bending beveling machine with an internal boring function for automatic welding comprises a machine tool 1, a drive control device 2, a floating tool rest 3, a hydraulic chuck locking device 4 and a lifting platform 5.
The drive control device 2 is mounted on the machine tool 1 and may include a driver and a rotary shaft. Wherein, the axis of rotation can rotate along the axis direction, and the driver can provide rotatory drive power for the axis of rotation.
The floating tool rest 3 can comprise a base, a cutter disc and a spring, wherein the base is fixed on the rotating shaft, the spring is arranged between the base and the cutter disc, and the cutter disc is provided with a cutting tool and a floating wheel. The cutting tool is arranged along the radial direction of the cutter head and can slide along the inner wall of the elbow, the cutting tool can comprise an inner boring tool and a groove tool, and the two tools are arranged on the floating tool rest 3 in a replaceable mode. The loose wheel sets up in the outside of cutter and can follow the return bend outer wall and float, and the length that the loose wheel can follow the outer wall and float can be 100 ~ 150 mm. When the cutting tool works, the cutting tool moves along the inner wall of the elbow, the floating wheel is tightly attached to the outer wall of the elbow, and when the floating tool rest 3 rotates along with the rotating shaft, the elastic force of the spring enables the cutter head to always perform irregular circular motion along the wall thickness direction of the elbow, so that the depths of inner bore holes manufactured by turning are uniform.
The hydraulic chuck locking device 4 is fixedly connected with the machine tool 1 and can comprise a hydraulic locking mechanism and a clamp. The hydraulic locking mechanism can provide variable clamping force for the clamp through hydraulic pressure, and the clamp can fix one pipe end of the bent pipe to be machined. The hydraulic chuck locking device 4 can fix the bent pipe, and the bent pipe is guaranteed not to shake in the turning process. For example, the hydraulic locking mechanism may be a jack and the clamp may be a fixed cylindrical clamp.
The lifting platform 5 is fixedly connected with the hydraulic chuck locking device 4 and can move left and right or up and down relative to the hydraulic chuck locking device 4, so that two ends of the bent pipe are positioned on the same horizontal plane. The lifting platform 5 adjusts the size by moving left and right and adjusts the height by lifting up and down to adapt to the pipe diameter of the bent pipe to be processed. The lifting platform 5 can be provided with a plurality of groups of bilaterally symmetrical limiting parts, and the limiting parts can slide left and right to enable the other end of the bent pipe to be fixed at a horizontal position. The locating parts at different positions can meet the fixing requirements of longer pipe fittings and shorter pipe fittings. For example, two sets of stoppers may be provided.
When the floating tool rest works, an inner boring tool can be arranged on the floating tool rest, after the inner boring tool is used for lathing an inner boring hole, the inner boring tool is replaced by a groove tool, and the outer groove is lathed.
Fig. 2 is a schematic structural diagram of a groove with an internal boring hole manufactured by the elbow groove locomotive, namely a novel groove form with an internal boring hole. As shown in fig. 2, the inner wall of a position 100-150 mm away from the pipe end is thinned to the thickness of the line pipe, the outer groove adopts a conventional V-shaped or double V-shaped groove, and the transition groove turning is carried out at the inclination of 1:3 after the inner boring is finished. The groove form can ensure that the automatic welding robot can smoothly carry out welding.
