Description

Technology Field

[0001] The present invention relates to a pipe beveling processing device, and more specifically, to a pipe beveling processing device with improved processing efficiency to enable easier processing of the end of a steel pipe. Background Technology

[0003] Generally, in industrial sites, beveling—cutting the ends of pipes at a specific angle—is essential prior to piping installation and welding.

[0004] This beveling process is an important step that facilitates the formation of the butt joint in pipe welds, thereby improving weld quality and enhancing the strength of the weld. Accordingly, various types of pipe beveling devices have been developed and are in use.

[0005] Conventional pipe beveling devices generally operate by fixing the pipe with a fixed jig and then cutting the end of the pipe using a rotating cutting tool.

[0006] However, since such conventional devices cannot stably fix and support the pipe, the pipe may shake or deviate from its position during processing, and because it is difficult to perform uniform processing along the entire 360-degree circumference, there was a problem of reduced processing quality.

Specific details for implementing the invention

[0017] Hereinafter, specific embodiments of the present invention will be examined in detail with reference to the attached drawings.

[0018] Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. These embodiments are provided to more fully explain the present invention to those with average knowledge in the art.

[0019] Accordingly, the shapes of components depicted in the drawings may be exaggerated to emphasize clearer explanations. It should be noted that identical components in each drawing may be illustrated with the same reference numeral. Furthermore, detailed descriptions of functions and configurations of known technology that are deemed to unnecessarily obscure the essence of the invention may be omitted.

[0020] First, the configuration of a pipe beveling processing device according to one embodiment of the present invention is as follows through FIGS. 1 to 8.

[0021] The processing device in the present embodiment comprises a lathe frame (10, 10') forming the main body of the device, a pipe mounting base (20) configured on the upper part of the lathe frame (10) for mounting a pipe (P), a processing blade (30) provided in a shape of inclination at a certain angle for beveling the front end of the pipe (P) mounted on the pipe mounting base (20), a rotating roller (40) for rotating the pipe in one direction for beveling by the processing blade (30), a pipe support (50) for rotatably supporting the rear end of the pipe (P) mounted on the pipe mounting base (20), a processing blade frame (60) provided to slide along the upper part of the lathe frame (10') while the processing blade (30) is mounted, and a rotating roller frame (70) on which the rotating roller (40) is mounted and supported.

[0022] At this time, in the present invention, the shelf frame (10, 10) is formed such that the first shelf frame (10) and the second shelf frame (10') are arranged at right angles to each other, and guide rails (not shown in the drawing) are formed in a groove shape on both sides of the upper surface of the shelf frame (10, 10') to guide the sliding movement of the processing blade frame (60) and the pipe mounting base (20).

[0023] In addition, in the present invention, two pipe mounting brackets (20) are arranged in a symmetrical form at a certain angle of inclination, and a plurality of rotating balls (21) are configured in the pipe mounting bracket (20). A mounting bracket support (80) having a "U" shaped cross-sectional structure is configured in the lower part of the pipe mounting bracket (20). A plurality of support grooves (81) are formed in the mounting bracket support (80) to allow for adjustment of the spacing between the pipe mounting brackets (20). The pipe mounting bracket (20) is provided with a fitting leg part (22) that can be fitted into the support groove (81). A fitting groove (22a) is formed in the fitting leg part (22) to prevent horizontal movement by being fitted into the support groove (81). A guide rail (82) is provided in the lower part of the mounting bracket support (80) to enable sliding movement along the rail groove on the upper part of the shelf frame (10).

[0024] In addition, it is preferable that the processing blade (30) be provided so that the angle can be adjusted as needed.

[0025] Meanwhile, in the rotating roller frame (70) of the present embodiment, a roller driving motor (41) is mounted to transmit rotational force to a plurality of rotating rollers (40), and a lifting motor (71) for adjusting the height of the rotating rollers (40) is configured on the upper part.

[0026] In addition, the pipe support (50) is provided with a mounting protrusion (not shown) on which the rear end of the pipe (P) can be mounted. Since this pipe support structure is a known technology, a detailed description of the configuration is omitted.

[0027] In the drawing, the unexplained reference numeral 61 represents a lifting motor for adjusting the height of the processing blade (30), and if necessary, it is preferable to attach a laser to one side of the processing blade frame (60) to mark the pipe portion to be processed.

[0028] Let us examine the effects of the operation of the pipe beveling processing device of the present invention, which has such a configuration.

[0029] The processing device of the present invention performs the processing operation while the pipe (P), which has been cut in a preceding process, is placed on the pipe support (20).

[0030] That is, at this time, the rear end of the pipe (P) is supported by the pipe support (50), and the processing blade frame (60) is slid along the shelf frame (10') so that the processing blade (30) is positioned at the area where beveling is to be performed. At the same time, the pipe support (50) and the mounting bracket support (80) are also slid along the shelf frame (10) to an appropriate position so that the pipe (P) can be stably supported by the pipe mounting bracket (20).

[0031] When the position setting is completed and power is applied, the processing blade (30) and the rotating roller (40) are lowered by the driving of the lifting motor (61, 71) to approach the pipe (P), and as the driving motor (31) is driven, the processing blade (30) rotates at high speed to perform beveling on the leading edge of the pipe.

[0032] At this time, as the rotating roller (40) in close contact with the pipe (P) is driven, the pipe (P) gradually rotates, and processing by the processing blade (30) is performed along 360 degrees.

[0033] In addition, during the process of rotating the pipe (P), stable support can be achieved by the pipe support (20) equipped with a rotating ball (21).

[0034] Afterward, when the above beveling process is completed, the pipe (P) that has completed the beveling process is moved to the next process (welding) with the processing blade (30) and the rotating roller (40) raised, and a new pipe (P) to be processed is placed on the pipe support (20), and the processing process can be repeated and performed continuously.

[0035] In addition, depending on the length or diameter of the pipe (P), the processing blade frame (60) can be moved to an appropriate position along the upper guide rail of the shelf frame (10') so that the work can be performed.

[0036] Accordingly, the beveling processing device of the present invention enables easy beveling of the end of a cut pipe, thereby exhibiting the effect of improving work efficiency and processing quality.

[0037] In particular, it demonstrates the advantage of more stable operation through a pipe mounting structure capable of accommodating various pipe diameters, along with pipe rotation by means of a rotating roller.

[0039] Meanwhile, FIGS. 9 and 10 show a configuration according to another embodiment of the present invention, wherein a cushioning block (83) made of rubber or latex is provided at the bottom of a support groove (81) formed in a support member (80) to cushion and support the fitting leg portion (22) of a pipe support member (20), and the cushioning block (83) has a plate-shaped support embedded inside and is elastically supported from below by a cushioning spring (84), and an elastic protective layer (83A) is formed on the upper surface of the cushioning block (83) to prevent surface damage and improve elasticity.

[0040] At this time, the elastic protective layer (83A) preferably has a mixed composition in the ratio of 20-40% by weight of molybdenum disulfide, 15-30% by weight of polyamide resin, 5-15% by weight of polybutylene succinate, 1-10% by weight of polyolefin elastomer, 5-10% by weight of urethane powder, 1-10% by weight of terpene resin, 5-10% by weight of sodium propionate, 1-10% by weight of behentrimonium chloride, 1-10% by weight of benzotriazole, 10-20% by weight of sodium silicon fluoride, and 1-10% by weight of chloramphenicol.

[0041] In addition, a lubricating film (85) made of a mixture of polytetrafluoroethylene (PTFE) and oleamide is attached to the side of the support groove (81) to reduce friction with the fitting leg portion (22).

[0042] When such a configuration is achieved, it can be seen that when the fitting leg portion (22) is inserted into the support groove (81) during the process of assembling the pipe mounting bracket (20) to the mounting bracket support member (80), primary cushioning support is provided by the cushioning block (83) and secondary cushioning support is provided by the cushioning spring (84), thereby enabling the distribution of the load of the pipe (P).

[0043] At this time, since an elastic protective layer (83A) is formed as a thin film coating on the surface of the cushioning block (83), deformation, cracking, and damage caused by friction with the insertion leg part (22) can be prevented.

[0044] In particular, since molybdenum disulfide is mixed into the elastic protective layer (83A), surface lubricity is improved, polybutylene succinate and polyolefin elastomer maintain coating stability and elasticity, sodium propionate performs the function of ensuring the coating has a uniform thickness overall through the catalytic function of the polyamide resin, and terpene resin improves adhesion efficiency with the buffer block (83). Additionally, the added behentrimonium chloride improves the mixing efficiency between the compositions, benzotriazole and sodium silicon fluoride suppress bubble generation and improve coating density during the application process of the composition for forming the elastic protective layer (83A), and chloramphenicol exhibits the advantage of performing an antibacterial function.

[0045] In addition, since a lubricating film (85) made of a PTFE / oleamide mixed material is attached to both sides of the support groove (81), noise and surface damage can be reduced due to the reduction of friction during the process of inserting the leg portion (22). At this time, the density and durability of the film are improved due to the mixed material rather than a single material, which provides the advantage of preventing breakage.

[0047] Furthermore, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the structure of the pipe beveling processing device of the present invention can be implemented with various modifications by those skilled in the art.

[0048] For example, in the above embodiment, the machining blade frame is described and illustrated as sliding along the lathe frame, but if necessary, the design can also be made so that the rotating roller frame slides.

[0049] Therefore, such modified embodiments should not be understood separately from the technical spirit or scope of the present invention, and such modified embodiments should be considered to be included within the appended claims of the present invention. Explanation of the symbols
