Embodiment 1
[0010] Example 1, see figure 1 , 2 ,, a circular hole 7 is processed on the center position of the centering roller frame that meets the design requirements, and a circular hole 9 is processed on the base that matches it. The two circular holes overlap on one side of the rolling direction; the eccentric circle The key includes a circular column 6 and a circular column 8, and the edge of the circular hole on one side of the two circular columns coincides in the rolling direction; the circular column 6 and the circular column 8 cooperate with the circular hole 7 and the circular hole 9 respectively, and the eccentric The round key rotates along the center of the circular column 8, and the circular column 6 is offset, so that the position adjustment of the centering roll in the vertical direction of rolling can be realized, and the center of the centering roll is always consistent with the rolling center line; in order to prevent the The eccentric circle and the centering roller...

The invention discloses a central adjustable centering roller device which comprises a base, a centering roller frame, a small-open hydraulic cylinder (1), a large-open hydraulic cylinder (22) and a centering roller (18). The small-open hydraulic cylinder (1) is connected with the large-open hydraulic cylinder (22), and the position of the frame of the centering roller (18) is fixed by a nut (21) on a piston rod of the large-open hydraulic cylinder (22). The central adjustable centering roller device is characterized in that a frame circular hole (7) is formed in the center of the centering roller frame, a base circular hole (9) matched with a base is formed in the base, a frame circular column (6) and a base circular column (8) are matched with the frame circular hole (7) and the base circular hole (9) respectively to form an eccentric circular key, a positioning block (2) is arranged below the small-open hydraulic cylinder (1), a pin shaft (5) and a bolt are arranged below the positioning block (2), the bolt moves along a long hole in the side face of the positioning block (2) when the pin shaft (5) vertically moves, a counter bored hole corresponding to the positioning block (2) is formed in the centering roller frame, so that the center of the centering roller can be adjusted and is consistent with a rolling line, and production requirements are met.
Description
Technical field: [0001] The patent of the present invention relates to the technical field of steel pipe production equipment, specifically a centering roller device with an adjustable center position. Background technique: [0002] At present, the central position of the centering roller in the piercing machine or pipe expansion background of the steel pipe production process is fixed. After the centering roller has been used for a period of time, the center position will shift due to the degree of wear of each roller and the gap between the parts and equipment, which will cause the center of the equipment to shift. , deviated from the rolling line, affecting the normal production. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a centering roller device with adjustable center position, which mainly solves the problem that the equipment center is shifted and deviated from rollin...
