Description
Technical Field
The invention relates to a double-drive structure of a long-table-surface multipoint press, belonging to the technical field of press parts.
Background
In the current society with higher and higher environmental protection requirements and higher energy-saving motor energy efficiency ratio requirements, the thickness of a silicon steel sheet material of a motor stator and a motor rotor is gradually reduced from 0.5mm to 0.35mm, 0.25mm or even 0.2mm, along with the continuous reduction of the material thickness, the tonnage of a die is continuously reduced, and the gap between a convex die and a concave die is also continuously reduced, so that a press machine with the same tonnage needs a platen which is wider and longer than the previous press machine and has higher operation precision.
In the prior art, when a very long table-board machine tool is involved, two ways are commonly used for controlling the spindle.
The first is to control a clutch brake unit at one end of the main shaft by using only one high-power single-output motor so as to control the rotation of the main shaft. The method has the great disadvantage in the use process, because the length of the spindle used by the large-table-board machine tool is long, only one clutch brake unit is controlled by one high-power motor, only the accurate control of one end of the spindle can be realized, and because the length of the spindle is long, under the combined action of factors such as gravity, friction, distortion and the like, the condition that the rotating speeds of the other end of the spindle and the motor control end are inconsistent or the lag angle is large is often caused, the spindle is easy to twist, and finally the movement tracks of all connecting rods distributed in the left and right directions are asynchronous, so that the operation accuracy of the sliding block is seriously influenced.
The second is to use two low-power single-output motors to respectively control two clutch brake units at two ends of the main shaft so as to control the rotation of the main shaft. Although various problems caused by the fact that the length of the main shaft is too long are solved, the rotating speeds of the two motors are different due to the manufacturing difference of the motors and the uncertainty of respective control, the rotating speeds of the two ends of the main shaft are inconsistent due to the rotating speed difference of the left main motor and the right main motor, the length direction of the main shaft is further twisted, the moving tracks of the connecting rods distributed in the left direction and the right direction are not synchronous, and the running precision of the sliding block is not high. Therefore, the requirement of high-speed precision stamping on the thickness of the current ultrathin materials of the stator and the rotor of the motor is difficult to ensure.

Further, the positions of the connecting rod (6) and the sliding block (7) are positioned at the outer side of the sliding block (7).
Furthermore, the belt pulley (3) and the flywheel (4) are symmetrically arranged on two sides of the main shaft (5).
Further, the longitudinal axes of the high-power double-output main motor (1) and the main shaft (5) are on the same straight line.
Furthermore, a step groove for installing the connecting rod (6) is formed in the main shaft (5), a mounting hole of the connecting rod (6) is clamped into the step groove, and the two sides of the step groove are limited to the axial horizontal movement of the connecting rod (6).
The invention has the advantages that: the invention can ensure the control consistency of the clutch brake units at the two sides of the main shaft to the maximum extent by simultaneously outputting the driving force from the left and the right of one high-power motor, thereby ensuring the consistency of the rotating speeds of all symmetrical positions in the whole length of the main shaft to the maximum extent, realizing the aim of realizing synchronous and accurate control of the main shaft by only using one high-power motor, avoiding the main shaft torsion phenomenon caused by the left and the right rotating speeds of the main shaft, and realizing the high synchronization of the motion tracks of all connecting rods of the main shaft. Finally, the consistency and the synchronism of the transmission of the connecting rods are ensured, and the high precision of the operation of the machine tool slide block is further ensured. The high-speed precision stamping requirement of the thickness of the current ultrathin materials of the motor stator and the motor rotor is ensured.
