Abstract

PURPOSE:To form large size panels without making the size of driving sources large by making driving sources for a first working station and a second and following working stations independent. CONSTITUTION:A main motor for the working station W1 and main motors for the second and following working stations W2 and others are controlled to be independently and synchronously driving each other. Independent press units 10 are respectively provided on each of the second to fourth working stations W2 to W4. A large size panel is carried in the first working station W1 to be formed by drawing and carried in the second working station W2 to be formed. Then, the panel is successively carried in the third and fourth working stations W3 and W4. Thus, large size panels are deep drawn without reducing production speed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a transfer press for molding a large panel.

[0002]

2. Description of the Related Art Conventionally, when molding a large-sized panel, a large-sized transfer press is used. The above-mentioned conventional transfer press has a plurality of slides, and while driving these slides by the same drive source, the transfer feeder sequentially conveys the panels to the respective processing stations to form the panels. There is.

[0003]

However, in the conventional transfer press, a large amount of work is required when performing the draw forming in the first step, so that the motor and the flywheel have a special specification larger than the standard product. In addition to the cost of the press itself because of the need for materials, it is necessary to increase the stroke of the slide or reduce the speed of the slide in order to prevent interference between the upper die and the attachment of the transfer feeder. There is a problem that decreases.
The present invention has been made in order to improve such a problem, and an object of the present invention is to provide a transfer press for a large-sized panel which does not require a special large-sized component and has high productivity.

[0004]

In order to achieve the above object, the present invention provides a transfer press having a plurality of processing stations, in which a link press having an independent drive source is arranged at the first processing station and a second processing station is provided.
Processing Stations The following is an arrangement of module presses having independent press units for each processing station and driven by a common drive source.

[0005]

[Operation] By intermittently operating the link press with the above configuration, it is possible to draw a large panel without increasing the size of the drive source, and it is not necessary to increase the slide stroke or reduce the production speed. Productivity is also improved.

[0006]

Embodiment An embodiment of the present invention will be described in detail with reference to the drawings. The drawing shows a transfer press in which a link press is arranged at the first processing station and a module type press is arranged below the second processing station, and in these drawings, 1 indicates a press body. The press body 1 is the most upstream first processing station W ₁
To four, and the second processing station W ₂ than the fourth working station W ₄ in total eight uprights 1a, are erected from the bed 1c 1b is spaced back and forth, the first processing station W ₁ Between the upper end of the upright 1a, the crown 2 in which a slide drive mechanism (not shown) is housed is arranged, and the second processing station W ₂ to the fourth processing station W
_A support beam 3 is installed between the upper ends of the ₄ uprights 1b, spaced apart in the front-rear direction.

In the drawing process of the first processing station W ₁ , the slide drive mechanism in the crown 2 is a link press constituted by links, and the clutch 4 and the brake 5 are provided on both sides of the crown 2. A main motor (not shown) can be operated independently of the second processing station W _{2 and} below. Below the crown 2, there is provided a slide 7 that moves up and down by being guided by a slide gib 6 laid on the upright 1a, and below the slide 7, a moving bolster that can be freely taken in and out of the press body 1. 8 are installed.

On the other hand, from the second processing station bolster W ₂ to the fourth processing station W ₄ , independent press units 10 are installed between the front and rear support beams 3 for each of the processing stations W _{2 to} W ₄ . These press units 1
The slide drive mechanisms 12 are housed in the crown 11 of 0, and the drive shafts 12a of these slide drive mechanisms 12 are connected and integrated by the connection shaft 12b at the upper part of the crown 11 and the drive shafts 12a A brake 13 is provided at the upstream end, and a clutch 1 is provided at the downstream end.
4 is provided, and the drive shaft 12a is rotated via the clutch 14 by a main motor (not shown).

On the opposite surface of the support beam 3, slide gibs 15 are laid for each of the processing stations W _{2 to} W _4, and the slide gib 15 is slid up and down by the slide driving mechanism 12. Is supported at each of the processing stations W _{2 to} W ₄ . Below the slides 16, a moving bolster 17 that can freely move in and out of the press body 1 is installed. Reference numeral 18 in the drawing denotes a transfer bar provided in parallel in the press body 1, which is driven by a drive mechanism 20 provided on the downstream side in synchronization with the operation of the press body 1.

To explain the operation, the main motor for driving the slide drive mechanism of the first processing station W ₁ and the main motor for driving the slide drive mechanism 12 of the second processing station W _{2 and} below are independent. , Are electrically controlled to rotate in synchronization. Large panels carried into the first processing station W ₁ now transfer bars 18, after being molded diaphragm first in first processing station W _1, between the first processing station W ₁ and the second processing station W ₂ It is conveyed to the second processing station W ₂ via the installed idle station i. Thereafter, the panels are sequentially sent to the third processing station W ₃ and the fourth processing station W ₄ to be molded, and the panel molded at the fourth processing station W ₄ is unloaded from the press body 1 as a product. . Although the idle station i is provided between the first processing station W ₁ and the second processing station W _{2 in} the above embodiment, the idle station i is omitted and a panel is directly provided from the first processing station W ₁ to the second processing station W ₂ . May be transported.

[0011]

As described above in detail, according to the present invention, since the driving sources for the first processing station and the second processing station and thereafter are independent, it is possible to draw a large panel at the first processing station. Even if you increase the slide stroke by intermittently operating the drive source,
This allows deep drawing of large panels without slowing down production. As a result, productivity of the transfer press can be improved and standard products can be used for main parts such as main motors, flywheels, clutches and brakes, so that the cost of the press itself can be reduced. Also, by enabling the molding and deep drawing of large panels, the versatility of the transfer press will be greatly expanded, and the operating rate will be improved.
