Description

A servo screw press

technical field

The utility model relates to automation equipment manufacturing technology, in particular to a servo screw press.

Background technique

Now for some precise forming or press-fitting precision parts, the presses used are hydraulic presses or mechanical punching presses, which have complex structures, low efficiency, and are difficult to maintain. The hydraulic press is driven by hydraulic oil, which has high pollution, high energy consumption, low forming precision, and large pressure and position errors. The forming height of the mechanical punch is limited, the speed cannot be adjusted, the positioning accuracy is poor, and the pressure is not controlled.

In addition, it is difficult for the hydraulic press to ensure the accuracy of press processing. After the machine fails, the oil leakage will pollute the use environment; due to the high speed of the punch press, the die will be greatly damaged, and the variable speed mold clamping cannot be realized, and there is no need for smart positioning.

Utility model content

In view of the above disadvantages, the purpose of this utility model is to provide a servo screw press, which drives the workbench connected with the roller nut to move up and down through the servo motor to drive the screw to rotate, so as to realize the pressure processing.

The technical scheme that the utility model adopts for realizing the above object is:

A servo screw press, comprising a body, characterized in that: the body is provided with a servo drive mechanism, a screw pressing mechanism and an intelligent electric control system; the servo drive mechanism includes a servo motor, a drive wheel and Timing belt, the screw pressing mechanism includes a roller nut, a ball screw and a worktable that cooperate with each other; wherein, the servo motor of the servo drive mechanism is connected with the ball screw of the screw pressing mechanism through a transmission wheel and a timing belt connect.

The servo drive mechanism is arranged on the rear side of the upper part of the body. The screw pressing mechanism is arranged on the upper front side of the machine body. The intelligent electric control system is arranged on the left or right side of the body. A base corresponding to the workbench is provided on the front side of the lower part of the machine body.

The drive shaft of the servo motor is equipped with a synchronous pulley (that is, the drive wheel). The synchronous pulley of the servo motor forms a transmission mechanism through the synchronous belt and the synchronous pulley on the ball screw. The roller nut driven by the ball screw is connected to the worktable.

The positive and negative rotation of the servo motor drives the rotation of the screw, and the rotation of the screw drives the roller nut to move up and down, and the roller nut is connected to the worktable to realize the up and down movement of the worktable to press the product. It is controlled by PLC, and the action requirements can be set arbitrarily through the touch screen of the intelligent electric control system.

The utility model has the advantages that: the mechanical structure is ingenious, and the servo motor directly drives the screw to rotate to drive the workbench to press the workpiece. The mechanical efficiency is high, because the direct drive of the servo motor reduces the mechanism in the driving process, so that the mechanical efficiency can reach more than 98%; the maintenance is simple, and no special maintenance is required during use. Repeated positioning accuracy is high, positioning accuracy can reach ≤0.01mm; pressure is stable, pressure error can reach ≤1%; fast response speed can be adjusted steplessly within the rated pressure and stroke range; skills are environmentally friendly, no pollution, low noise and zero loss of useless work .
