Hollow shaft applied to round steel necking machine

Abstract

The invention relates to a hollow shaft applied to a round steel necking machine. The hollow shaft applied to the round steel necking machine comprises a main machine bottom plate and a box body, and is characterized in that the box body is arranged at the upper end of the main machine bottom plate; a hollow shaft is arranged in the center of the inner side of the box body; a main belt pulley is arranged on the hollow shaft in a matched manner; a first supporting ring, a second supporting ring, a third supporting ring and a fourth supporting ring are sequentially arranged on the outer side of the hollow shaft; at least one ball head is arranged on each of the four supporting rings; a heading arm is arranged on the upper side of each ball head; a spherical seat is arranged at the position, corresponding to each ball head, of each heading arm; a return spring assembly is arranged on the outer side of each heading arm; a motor belt pulley is arranged at the lower side of the main belt pulley; the motor belt pulley is installed on a variable frequency motor; a plurality of heading dies are arranged on the side, away from the spherical seat, of the heading arms; containing grooves are arranged in the inner sides of the heading dies; the inner sides of the containing grooves are used for machining round steel pipes; heat detection devices are arranged on the heading dies; the heat detection devices are electrically connected to the variable frequency motor; and the heat detection devices are used for monitoring the temperature of the heading dies.

Description

technical field [0001] The invention relates to the field of machining, in particular to a hollow shaft applied to a round steel necking machine. Background technique [0002] In the prior art, in the process of steel pipe production, it is first necessary to perforate the round steel to form the original pipe, and then carry out subsequent processing. The efficiency of the existing equipment for the perforation of the round steel is generally low, and the accuracy is not high enough. The existing The round steel piercing and necking machine is inconvenient to operate. During the steel pipe shrinking process, the yield is poor, the noise is high, and the energy consumption is high. After the steel pipe enters the furnace, it is not centered, causing the center to shift and get stuck. In this application, the unmanned operation of the necking machine can be realized through the eccentric hollow shaft, with a high degree of automation, and the working frequency of the variable...
