Automatic line LM1591

The automatic line LM1591 is designed for processing pump rods with a rod body diameter: 3/4″,  7/8″,  1″ and rod lengths of 7.62 m, 8 m and 9.14 m.

The line consists of ten one-sided double-spindle machines, a workpiece accumulator, a step conveyor that allows you to move the rods both in the longitudinal and transverse directions, and an unloading mechanism. Two-spindle machines that perform machining of parts consist of a rigid cast-iron base, two power tables on which spindle headstocks are installed.

Line technology:

• at the first operation, from 2 sides of the pump rod, the thrust shoulder is turned, the chamfers on the shoulder, and the nipple is pre-turned.
• in the second operation, the end of the nipple and the chamfer of the nipple for threading are trimmed, and the threaded groove is sharpened.
• in the third operation, the threaded surface is knurled.
• The fourth operation is thread rolling.
• in the fifth operation, caps are pressed in to protect the threads.

The line is fully automated.
