A rod and pipe material cutting machine with end face cam driven by AC servo motor

Abstract

Provided is a rod-pipe material blanking machine of an alternating-current servo motor driving end face cam. Three sets of identical end face cam forging mechanisms are evenly distributed in the periphery direction symmetrically. Each forging mechanism comprises an alternating-current servo synchronous motor arranged on a main machine body. Each alternating-current servo synchronous motor is connected with an upper shaft of a cam through a speed reducer. The lower end face of each cam is matched with the top end of a pushing rod. A reset spring is arranged between the middle portion of each pushing rod and the main machine body. The lower end of each pushing rod is connected with a die adjusting nut through a guiding strip. A hammer is connected into each die adjusting nut through threads. Each hammer is provided with a blanking die. Rod-pipe materials to be machined are arranged between the three blanking dies. Meanwhile, the die adjusting nuts are externally connected with die adjusting worm wheels through die adjusting sleeves, the die adjusting worm wheels are matched with worms, and a small servo motor arranged on the main machine body provides power for the worms. The cams and the pushing rods form the end face cam. The purpose of near and clean blanking can be achieved, a blanking section is high in quality, materials are saved, energy loss is lowered, and production efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of material processing machinery, and in particular relates to a rod and pipe material cutting machine with an AC servo motor driving an end face cam. Background technique [0002] The blanking of metal rods and pipes widely exists in industrial practice. Traditionally, lathes, band saws, thermal cutting machines, punching machines and other machines are used for blanking, and lathes, band saws, and thermal cutting are used for blanking. Low production efficiency, waste of raw materials and other shortcomings. Using a punching machine for shearing and blanking has a large blanking force and high energy consumption, and the cross-section of the rolled bar material presents an obvious horseshoe shape, which has a great impact on subsequent processing. The core rod is used for auxiliary blanking, the process is more complicated and it is easy to deform the tube material. That is, there are problems such as po...

[0002] The blanking of metal rods and pipes widely exists in industrial practice. Traditionally, lathes, band saws, thermal cutting machines, punching machines and other machines are used for blanking, and lathes, band saws, and thermal cutting are used for blanking. Low production efficiency, waste of raw materials and other shortcomings

Using a punching machine for shearing and blanking has a large blanking force and high energy consumption, and the cross-section of the rolled bar material presents an obvious horseshoe shape, which has a great impact on subsequent processing. The core rod is used for auxiliary blanking, the process is more complicated and it is easy to deform the tube material

That is to say, there are problems such as poor section quality, waste of materials and low production efficiency when using the existing common blanking machine for blanking.
