Description

[Detailed Description of the Invention] The present invention relates to a device for transporting and fixing a die in a press.

Conventionally, presses have been provided with separate mold conveying devices and mold fixing devices, requiring a large space to install the devices and making the operations for different uses complicated.

The present invention is an attempt to solve such problems, and is a mold for a press that can be used for both transportation and fixation, and that uses the lifting and lowering motion of a double-acting fluid cylinder to simplify the switching operation between transportation and fixation. The purpose of this invention is to provide a transport and fixing device for

To explain the embodiment of the device of the present invention with reference to the drawings, FIGS. 1 and 2 are schematic diagrams of the embodiment device incorporated into a press, and FIGS. 3, 4, and 5 are diagrams of the embodiment device. It is a structural diagram.

A plurality of grooves 6a are provided in the upper surface of the bolster 6 in the front-rear direction.

A double-acting hydraulic cylinder 8.8 that operates in the vertical direction is embedded in the bottom near the front and rear of the groove 6a, and is held down by separate holding plates 7, 7.

The piston 9 of the hydraulic cylinder 8 operates upward or downward;
A threaded portion 10a provided at the top of the piston rod 10 projects upward from the hydraulic cylinder 8.

The guide table 2 provided in the groove 6a has a U-shaped cross section and has a length that spans almost the entire length of the mea.

The U-shaped bottom of the guide table 2 is screwed onto the threaded portion 10a of the hydraulic cylinder 8.

A plurality of rollers 14 for transporting molds are arranged horizontally above the inside of the U-shape.

Further, flange portions 2a, 2a are provided to protrude above both sides of the U-shape.

The long guide table 2 is divided into three parts: a front member screwed onto the front hydraulic cylinder 8, an intermediate member 15, and a rear member screwed onto the rear hydraulic cylinder 8.
Step portions 2b are provided on the dividing surface of No. 5 and the dividing surfaces of the intermediate member 15 and the rear member, respectively, so that the intermediate member 15 is engaged between the front member and the rear member.

Since the intermediate member 15 is divided, a machining error in the center distance between the front and rear hydraulic cylinders 8, 8 can be absorbed by adjusting the length of the intermediate member 15.

On the other hand, an L-shaped member 12.12 is provided on the bottom surface of the mold 3 to protrude into i6a and to face the L-shaped member 12.1.
The opposing shoulders 12a, 12a of the guide table 2 are attached to the flanges 2a, 2 on both sides of the guide table 2 when the guide table 2 is lowered.
It is constructed so as to be engaged with a.

In addition, there are brackets 4 on the left and right in front of the press bolster.
4 is fixedly installed, a pin 5 is implanted in the bracket 4,
The auxiliary guide table 1 is rotatably held by the pin 5.

A plurality of rollers 11 for transporting molds are horizontally provided on the auxiliary guide tables 1, 1.

The auxiliary guide tables 1 and 1 are used as bolsters 6 when transporting the mold.
It is used by being rotated forward (as shown in Figure 4), and the bolster 6 is used so as not to interfere with the press work.
Closed on the front.

Next, the operation of the device of the present invention will be explained.

When fixing to the bolster 6 of the mold 3 as shown in FIG. 5, the double-acting hydraulic cylinders 8, 8 are operated downward.

The front and rear members of the guide table 2 screwed to the front and rear hydraulic cylinders 8.8 are pulled down, and the flanges 2a, 2a are lowered to form an L fixed to the bottom of the mold 3. Shoulders 12a, 12 of mold part 12.12
The mold 3 is fixed to the bolster 6 by engaging with the shoulder portion 12a+ and urging the shoulder portion 12a downward.

At this time, the intermediate member 15 installed between the front member and the rear member
also descends due to its own weight.

Further, at this time, it is natural that the upper surface of the roller 14 is sunk downward from the bolster surface.

Next, when the press work is completed and the molds are to be transported, the upper mold portion 13 of the molds is first removed from the slide and stacked on the mold 3, as in the case of normal mold replacement.

Next, the double-acting hydraulic cylinders 8, 8 are operated upward.

The front and rear members of the guide table 2 screwed onto each other are pushed up, and the intermediate member 15 is raised together via the step portions 2b, 2b, so that the flange portions 2a, 2a are
As the mold members 12.12 are lifted off from the shoulders 12a, 12a, the plurality of rollers 14 rise and hit the lower surface of the mold 3, pushing the mold 3 up and floating onto the upper surface of the bolster 6.

The mold 3 thus becomes movable on the rollers 14 and can be easily transported out of the press via the rollers 11 of the auxiliary guide table 1.

Conversely, when installing a new mold 3 on the bolster 6, this can be accomplished by performing the above operations in reverse.

The device of the present invention has the above-mentioned structure and function, but since it can be used for both transportation and fixation with a single device, and is compactly incorporated into the groove of the bolster, the transportation device and fixation device are provided separately. Does not require a large installation space compared to

Further, the operation is simple as it is only necessary to switch between raising and lowering a double-acting hydraulic cylinder buried in the groove, and the mold changing work can be made highly efficient.

In addition, since the guide table is divided into three parts: the front member, the intermediate member, and the rear member, even if there is a manufacturing error in the mounting position of the front and rear hydraulic cylinders, it can be easily absorbed by adjusting the length of the intermediate member. When repairing a hydraulic cylinder, only the relevant hydraulic cylinder can be easily removed and installed.
