Problems solved by technology
Existing head beveling machines have relatively high requirements on the ellipticity of the head. When the head has a certain ellipticity, the blunt edge of the processed bevel has inconsistent dimensions, and the bevel surface is not smooth. During the butt welding process, due to local unevenness and discontinuity, the welding quality is unstable, resulting in welding defects such as pores and slag inclusions, which affect the welding quality and are difficult to adapt to occasions that require high quality
In addition, the existing head beveling machines have poor adaptability to heads of different materials and thicknesses, and cannot meet the needs of different bevel types.

Embodiment Construction
[0021] Attached below figure 1 And attached figure 2 The present invention is further described in detail.
[0022] A head gas cutting beveling machine, including a load-bearing system, a support rotation system and a positioning processing system;
[0023] The load-bearing system is composed of 4-6 load-bearing legs 2, support plates 4, and supports 5. The load-bearing legs 2 are vertically fixed on the ground with anchor bolts, and the support plate 4 is horizontally fixed above the load-bearing legs 2. Install 4-6 supports 5 above the support plate 4, the number of supports 5 is the same as that of the load-bearing legs 2, and the positions of the load-bearing legs 2 are staggered, and they are evenly arranged on the support plate 4, and the supports 5 and the support plate 4 are welded fixed;
[0024] The supporting rotary system is composed of a rotary disc 6, a support wheel 8, a guide plate 7 and a speed-regulating motor 1. The rotary disc 6 is supported by a suppor...

The invention discloses a sealing head gas cutting groove machine. The machine comprises a bearing system, a support rotation system and a positioning processing system; the sealing head gas cutting groove machine runs stably and reliably and has the advantages of being neat in groove machining and uniform in blunted edge, the change of the sealing head roundness can be tracked in real time according to a tight wheel, radial displacement adjustment is conducted on a cutting gun synchronously, consistency and uniformity of the groove size are guaranteed, and the great significance in improvingthe product quality and improving the work efficiency is achieved. The machine is applicable to gas cutting machining of sealing heads made of carbon structural steel, low alloy structural steel, stainless steel, composite steel plates and the like. The sealing head gas cutting groove machine is easy and convenient to operate and capable of conducting gas cutting machining of different groove types on sealing heads of different types, different specifications and different thicknesses.
Description
technical field [0001] The invention relates to a processing device for a rotary workpiece, in particular to a head gas cutting beveling machine. Background technique [0002] The pressure vessel head is one of the main pressure components of the pressure vessel. During the manufacturing process of the pressure vessel, it usually needs to be butt welded with the cylinder. According to the structure, size, material, plate thickness and welding method of the vessel, the seal The end face of the head is processed into different types of grooves to meet the needs of the welding process. Since the processing of the head is pressed by a mold and formed by spinning, there is inevitably a certain degree of ellipticity. Existing head beveling machines have relatively high requirements on the ellipticity of the head. When the head has a certain ellipticity, the blunt edge of the processed bevel has inconsistent dimensions, and the bevel surface is not smooth. During the butt welding...
