Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for driving a plurality of flywheels.

Conventionally, in machine tools, especially press machines, the flywheel is driven by transmission to an electric motor via a belt, storing energy and using clutches and brakes to transfer that energy to the gear train, crankshaft, and connecting rod. Tefless work is performed by converting the vertical movement of the

. Recently, it has been proposed to automate the installation of a plurality of press units onto one machine frame as one line.

In this case, since each press unit is provided with an electric motor to drive each flywheel, the number of electric motors increases, resulting in high costs, and it is extremely troublesome to adjust the operation timing of each press unit. It has some problems.

The present invention was developed in view of the above circumstances, and its purpose is to provide a flywheel drive device that allows a plurality of flywheels to be driven by one electric motor.

Embodiments of the present invention will be described below with reference to the drawings.

C-shaped frames 2 are arranged side by side at intervals on a base 1, and a bed 3 and a slide 4 are provided between each C-shaped frame 2 to constitute a press unit 5, respectively.

As shown in FIG. 2, each of the press units 5 is equipped with a flywheel 6 that is rotatable relative to the C-shaped frame 2, and a ring-shaped gear I is fitted onto the flywheel 6, and is fixed by positioning pins 8 and bolts 9. In addition, the flywheel 6 is transmitted to the slide 4 via a clutch/brake, a gear train, a crankshaft, and a connecting rod (not shown).

Further, the flywheel 6 of each press unit 5 is arranged in a straight line, and the ring gears T are in mesh with each other at the opening 10 of the C-shaped frame 2. Pinion 1 installed in electric motor 11
2 are meshing.

When one electric motor 11 is driven by a motor, the pinion 12
is rotated, and one flywheel 6 is rotated.

This rotation is transmitted to the adjacent flywheel 6 via the ring gear 7, and similarly, the adjacent flywheel 6
All the flywheels 6 rotate at the same time.

Therefore, since only one electric press is required, the cost is reduced, and since each flywheel 6 rotates at the same time in synchronization, the operation timing of each press unit can be easily adjusted.

4 and 5 show other embodiments, in which the base 1
and the frame 2 form a press frame body having recesses 20, 21 on both sides, and a lower part 20a of each recess 20, 21,
21a and beds 3 and 3 on top 20b.

A slide 4 is provided on the frame 21b facing each other, and a prime mover 11 is provided on the upper part of the frame 1.

The pinion 12 of the prime mover 11 meshes with the ring gear 71 of the first flywheel 6□, and the ring gear 71 meshes with the ring gear 12 of the second flywheel 62, and each flywheel 61.62 are flank brakes 221, 222, gear train 23. ．． 232, eccentric shafts 24□, 24°, and connecting rods 251, 252, which are respectively transmitted to the slide 4.4.

Since the present invention is constructed as described above, a plurality of flywheels 6 can be driven simultaneously by one electric motor 11.
Since only one unit is required, costs can be reduced, and each flywheel 6 can be driven at the same time and with the same relative drive cycle, and the operating parts such as the slides of the press connected to each flywheel 6 can be driven at the same time. Relative movement timing can be easily adjusted.

In addition, since the ring-shaped gears 7 externally fitted and fixed to each flywheel 6 were meshed with each other to connect the flywheels 6, the ring-shaped gears for connection were specially attached to the frame 2.
There is no need to support the structure, there is no need to provide a support shaft, a bearing, etc., the structure is simple, the whole is compact, and costs can be reduced.
