Description

[Detailed Description of the Invention] This invention relates to a feeder power switching device in a transfer press that is miniaturized as a whole by providing a dedicated power source for the feeder on the axis of a main shaft interlocked with the press.

The purpose of this invention is to provide a dedicated power source for the feeder via a clutch mechanism on the axis of the main shaft that interlocks with the press, thereby making the device itself a compact unit that can be easily attached to the press. An object of the present invention is to provide a feeder power switching device for a transfer press.

The following invention will be described in detail with reference to an illustrated embodiment.

In the figure, reference numeral 1 denotes a transfer press, and a main body 2 of the apparatus is installed on the side in an upright position.

The main body 2 is formed from a substantially cylindrical housing 3,
A side portion of a gear chamber 4 provided at the lower part of the housing 3 is fixed to the transfer press 1, and a power take-off shaft 5 is inserted through the center of the housing 3.

The lower end side of the power take-off shaft 5 passes through a bearing 6 provided at the bottom of the gear chamber 4, projects downward from the gear chamber 4, and is linked to a transfer feeder via a power system (not shown).

Further, a bevel gear 7 is rotatably supported on the power take-off shaft 5 within the gear chamber 4 .

The bevel gear T is meshed with a bevel gear 10 of a main shaft 9 supported on the transfer press 1 side of the gear chamber 4 via a bearing 8.

The power take-off shaft 5 is linked to and drives a feeder (not shown), and the boss portion of the bevel gear 7 supported by the power take-off shaft 5 has clutch teeth that mesh with the clutch mechanism 11. 7a is formed.

The clutch mechanism 11 is inserted into the power take-off shaft 5 within the housing 3, and has a sleeve 13 whose lower end side is splined 12 to the power take-off shaft 5 and rotates integrally therewith.

The sleeve 13 consists of an outer cylinder 13a that is slidable in the axial direction with respect to the housing 3, and an inner cylinder 13c that is rotatably supported within the outer cylinder 13a via a bearing 13b. The clutch teeth 13d which are removably engaged with the clutch teeth 7a of the bevel gear 7 are connected to the outer cylinder 1.
A dog 14a that acts on a limit switch 14 provided on the upper outer periphery of the housing 3 is provided on the upper end side of the housing 3a.

Further, a pressure chamber 15 is formed between the outer cylinder 13a of the sleeve 13 and the housing 3.

This pressure chamber 15 is divided into chambers 15a and 15b by a piston 13e formed by expanding an outer cylinder 13a, and each chamber 15a and 15b is operated by the above-mentioned □ cytoswitch 14 through pipes 16 and 17. Solenoid valve 18
is connected to a hydraulic power source 19 via.

On the other hand, clutch teeth 13f are also formed at the upper end of the inner cylinder 13c of the sleeve 13, and the clutch teeth 13f can be freely engaged and disengaged with the clutch teeth 21a at the bottom of the collar 21, which is spline-engaged with the rotating shaft 20a of the feeder dedicated power source 20. It is designed to be engaged.

The feeder dedicated power source 20 is, for example, a deceleration motor, and is fixed to the top of the housing 3, so that the feeder (not shown) can be slowly driven by the following action.

When the feeder is operated in conjunction with the transfer press 1, hydraulic pressure is supplied to the upper pressure chamber 15a, the sleeve 13 is lowered, and the clutch teeth 13d of the sleeve 13 are connected to the clutch teeth 7a of the bevel gear T. engage.

As a result, 90 rotations of the main shaft are transmitted to the inner cylinder 13c of the sleeve 13 via the bevel gears 10 and 7, and further transmitted to the feeder via the power take-off shaft 5, and the feeder is driven in conjunction with the transfer press 1. be done.

If an overload is applied to the power take-off shaft 5 side during operation, the trapezoidal clutch teeth will be removed. The sleeve 13 is pushed up by the action of a, and the dog 14a is separated from the limit switch 14, turning OF.
F, so the solenoid valve 18 is switched and the chamber 1
The oil that had been supplied to the chamber 5a is supplied to the chamber 15b, which causes the sleeve 13 to rise and cause the clutch teeth to move upward. a, 13
d is released, and the clutch teeth 21a and 13f
90 rotation of the main shaft is not transmitted to the power take-off shaft 5, and at the same time, the shaft 5 is locked by the brake mechanism of the feeder dedicated power source 20.

Next, when the feeder is operated at a slow speed by the feeder dedicated power source 20, hydraulic pressure is supplied to the chamber 15b side of the pressure chamber 15 to raise the sleeve 13, and the clutch teeth 13b and collar 2
1 clutch tooth 21a is engaged.

If the feeder dedicated power source 20 is rotated in this state, the 200 rotations of the power source will be transmitted from the power take-off shaft 5 to the feeder through the inner cylinder 13c of the sleeve 13, so the feeder will be slowed down regardless of the main shaft 9. It can be made to work.

As detailed above, this idea is based on a feeder dedicated power source installed on the axis of the main shaft linked to the transfer press.
Since the rotation of the main shaft and the rotation of the feeder-specific power source are selectively transmitted to the power take-off shaft using a sleeve that is movable along the main shaft, the clutch mechanism etc. can be compactly housed inside the housing that accommodates the main shaft. As a result, the entire structure can be made smaller, and it can be easily mounted on a transfer press.

In addition, the sleeve is composed of a slidable outer cylinder and an inner cylinder rotatably supported by the outer cylinder, so that the rotation of the main shaft and the rotation of the power source dedicated to the feeder are transmitted to the power extraction shaft via the inner cylinder. As a result, the power can be transmitted more smoothly than in a case where the power is transmitted through a sliding and rotating sleeve, and wear of the members that ensure the sealing of the pressure chamber can be reduced.
