[0001] DESCRIPTION

[0002] A WHEEL ASSEMBLY WITH A CRUSHER USED FOR INTERNAL

[0003] DEBURRING OF PIPES

[0004] Field of the Invention

[0005] This invention relates to a wheel assembly with a crusher for use in a deburring apparatus for removing welding burrs formed on the inside of a pipe.

[0006] Background of the Invention

[0007] Pipe manufacturing at ERW Pipe Mills is carried out using electric resistance welding (ERW). After welding, burrs are formed in the welding area on the inner and outer surfaces of the pipes / profiles. The burrs formed on the inner surface of the pipe / profiles are called internal burrs and the burrs formed on the outer surface are called external burrs. The burrs formed after welding negatively affect the product quality, therefore a burr surface is not desired in the final product. In the state of the art, deburring apparatuses are provided to deburr the inside of the pipe after welding. The aforementioned deburring apparatuses comprise a guide wheel which is located at the top and bottom portions of the end portion of a tubular part, and at least one crushing wheel portion. In the said deburring apparatus, it is intended to make a notch on the burr formed inside the pipe by means of the crushing wheel.

[0008] Crushing wheels in the deburring apparatus in the state of the art consists of two opposing circular parts which form the wheel and have slots therein, a crusher which is located in the slots between the two circular parts and the screws for fixing two circular parts together. For the installation of the said crushing wheel, the two circular parts are positioned opposite each other, the crushing part is inserted into the slot therebetween and the fasteners (screws, bolts, etc.) are inserted into both circular parts through bolt holes and the two circular parts are fixed together and compressed, thereby the wheel assembly with a crusher is completed. In the said process, the wheel assembly is formed by aligning and joining two circular parts. Hence, aligning the crushers on the wheel is challenging and time consuming. Moreover, during installation, particles / unwanted materials from the external environment may get caught between the two circular parts or the slots thereof and this causes problems such as incorrect installation and unproper fitting of the crushing part into the slot.

[0009] In the state of the art, another technical problem which occurs in the crushing wheel assembly of the deburring apparatus is a situation where two circular parts can easily be separated or crushed due to the fact that these parts are assembled together. Since the two circular parts are assembled together, the service life of the crushing wheel assembly is short.

[0010] Chinese patent application no CN201244695, known in the state of the art, relates to an apparatus which is used for internal deburring of pipes after ERP welding. The said apparatus has a deburring blade at the end portion, a position wheel at the top and bottom portions, and a wheel with a blade structure (wheel with a crusher) at the top portion. The details of the wheel with a crusher are not mentioned in the said application.

[0011] Summary of the Invention

[0012] The objective of the invention is to provide a wheel assembly with a crusher which is used for a deburring apparatus for removing welding burrs formed on the inside of a pipe and which is easy to assemble.

[0013] The objective of the invention is to provide a wheel assembly with a crusher which is used for a deburring apparatus for removing welding burrs formed on the inside of a pipe and which eliminates the alignment problem caused by the staff. The objective of the invention is to provide a wheel assembly with a crusher which is used for a deburring apparatus for removing welding burrs formed on the inside of a pipe and which is more robust (has a longer service life).
