[CN 201710435861.6] steel pipe punching and shearing machine
[CN 201710435861.6] Title of a steel pipe punching and shearing machine: Application number of a steel pipe punching and shearing machine: CN 201710435861.6 Applicant: Shandong Electric Power Capital Construction Corporation Application Date: 2017-6-12 Patent Type: Application for Invention The present invention relates to a steel pipe punching and shearing machine, which is especially suitable for processing steel pipe ends in T-shaped joints of steel pipe railings of ladder platforms for electric power and construction projects, and belongs to the technical field of mechanical equipment. The steel pipe punching and shearing machine of the present invention includes a bracket auxiliary system (1), a locking device (2), a tool holder device (3), a transmission device (4), and a pressure rod (5), which can be used to cut the side pipe wall of the pipe (7). As an improvement, it also includes a dial block device (6). The cam plate (403) is adjusted to an outer cam through the dial block device (601), and the pressure rod (5) is pressed to drive the cam plate (403) to rotate. The shaft (409) drives the transmission plate (401) and the transmission plate (402) to move, thereby driving the sliding tool holder (302) to move downward, complete the shearing of the pipe wall on the lower side of the pipe fitting (7); reset the pressure rod (5), adjust the cam plate (403) into an internal cam through the dial block device (602), press the pressure rod (5), and complete the shearing of the pipe wall on the upper side of the pipe fitting (7). The invention can complete a variety of pipe diameter steel pipe end punching and shearing operations, processing a molding, can improve the efficiency of the steel pipe railing T-joint group and welding quality.
