Rotary through type cold drawing structure of welded pipe equipment

Abstract

The invention relates to a rotary through type cold drawing structure of welded pipe equipment. The rotary through type cold drawing structure of the welded pipe equipment comprises a drawing rack, alifting screw rod, a lifting sliding block, a lifting adjusting nut, a dial, a transmission triangular belt, a dragging motor, a belt pulley, a reinforcing support plate, a rack cover, an end cover and a drawing die. The lifting screw rod is installed on the inner side of the drawing rack, the lifting sliding block is installed on the front face of the rack through the end cover, the drawing die is fixedly installed on the lifting sliding block, the lifting adjusting nut is installed at the upper end of the drawing rack, the dial is installed at the joint of the lifting adjusting nut and the drawing rack, one end of the transmission triangular belt is connected with the dragging motor, and the other end of the transmission triangular belt is connected with the belt pulley. The rack cover is installed on the end surface of the upper side of the drawing rack, and the reinforcing support plate is fixedly installed on the side surface of the drawing rack. The rotary through type cold drawing structure of the welded pipe equipment is simple in structure, the belt pulley is connected with the drawing die, the drawing die is rotated through kinetic energy generated by the dragging motor,a welded pipe passing through the drawing die can be evenly stressed, therefore, the purpose of finishing the size of the welded pipe is achieved, and the production efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of welded pipe equipment, and in particular relates to a rotary-through cold-drawing structure of welded pipe equipment. Background technique [0002] With the acceleration of domestic modernization, there are more and more application fields of high-frequency straight seam welded pipes, and the requirements for the size of welded pipes are also getting higher and higher. The dimensional accuracy of high-frequency welded pipes mainly depends on the precision of the sizing mechanical parts and rolls of welded pipe equipment. Its main structure is to install the rolls on the gantry frame and the vertical roll frame, and adjust the rolls to control the ruler accuracy of the welded pipe through the adjustment screw on the frame respectively. The welded pipe produced in this way is generally It is difficult to guarantee the dimensional accuracy. It is generally used in furniture, construction and other industries...

Problems solved by technology

[0002] With the acceleration of domestic modernization, there are more and more application fields of high-frequency straight seam welded pipes, and the requirements for the size of welded pipes are also getting higher and higher. The dimensional accuracy of high-frequency welded pipes mainly depends on the precision of the sizing mechanical parts and rolls of welded pipe equipment. Its main structure is to install the rolls on the gantry frame and the vertical roll frame, and adjust the rolls to control the ruler accuracy of the welded pipe through the adjustment screw on the frame respectively. The welded pipe produced in this way is generally It is difficult to guarantee the dimensional accuracy. It is generally used in furniture, construction and other industries that do not require high dimensional accuracy of welded pipes. For applications with high dimensional requirements, only welded pipes that have undergone cold drawing process can be used instead. The cold drawing technology is complicated. It is necessary to leave the welded pipes produced by the welded pipe equipment as blank welded pipes suitable for the cold drawing process, and then perform one or more cold drawing to obtain the welded pipes with the corresponding size requirements, so that the manufacturer's investment in workshops, equipment, technology, and personnel increase, which directly increases the production cost, which is not conducive to the long-term development of the enterprise
