Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a hot slab width press tool changing device for hot rolling equipment, and in particular to a compact hot slab width press tool that facilitates maintenance of the press machine. Relating to a switching device.

[Conventional technology]

In the above-mentioned type of device as described in Japanese Patent Publication No. 58-48256, a horizontal forging machine is rotatably provided with a ring-shaped die magazine for storing forging tools in a radial manner, and a cylinder for raising and lowering the forging tools is installed in the horizontal forging machine. It was installed on a horizontal forging machine.

[Problem to be solved by the invention]

In the prior art, the width of the die magazine that stores the forging tools is larger than that of the forging machine, which makes maintenance of front and rear equipment difficult, especially in hot slab width press machines. Furthermore, since the forging tool is moved up and down by direct cylinder motion, the height of the lifting device becomes high, and the changing device requires a large space.

Furthermore, the press movable device that is located below the die magazine and moves the forging head requires the die magazine to be removed for maintenance, which requires a great deal of effort.

It is an object of the present invention to make a hot slab width press tool changer compact.

Another object of the invention is to facilitate maintenance of a press mover that moves a forging head in a hot slab width press tool changer.

[Means to solve the problem]

To achieve the above object, the present invention provides a hot slab width press tool changing device for use in a press machine having a reciprocating block for holding a press tool, the tool changer being substantially parallel to the direction of reciprocating movement of the reciprocating block. To provide a hot slab width press tool changing device including a tool storage device and a tool lifting device which are adapted to reciprocate in different directions.

[Effect]

The tool storage device and the tool lifting device that constitute the hot slab width press tool changing device according to the present invention are configured to move in a direction parallel to the reciprocating direction of the reciprocating block of the press machine, and are configured to move in a direction parallel to the reciprocating direction of the reciprocating block of the press machine. It moves to a predetermined position during replacement, and retreats to a position where it does not get in the way during press machine maintenance.

〔Example,〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 10 denotes a hot slab width press tool changing device according to an embodiment of the present invention, which is installed in a press machine 1.

The press 1 has a reciprocating block 2 that is reciprocated by a cylinder 6. The reciprocating block 2 is equipped with a press tool 4 for pressing a material to be rolled 5 and a holder 3 for holding the press tool. The material to be rolled 5 is rolled by operating the cylinder 6 to move the reciprocating block 2 and being pressed from both sides by the press tool 4.

The hot slab width press tool changer @10 includes a rail 7 provided on the top of the press 1 parallel to the direction of movement of the reciprocating block 2, a tool storage cart 8 that moves on this rail, and a self-propelled cart for lifting and lowering tools. Contains 9.

The tool storage cart 8 stores a new press tool 4a and holder 3a to be replaced with the press tool 4 and holder 3 attached to the reciprocating block 2, and moves on the rail to a position where tools etc. can be replaced. It is movable. The tool storage cart 8 also has a space 8a for storing the replaced press tool 4 and holder 3, as shown in FIG.

The self-propelled cart 9 for raising and lowering tools has hooks 11 for hanging press tools and holders. Hook holder 12, cylinder 13 for opening and closing the hook. It includes a chain 14 and wheels 15 for raising and lowering these, and a hoisting wheel 16 for winding up the chain.

As shown in FIGS. 4 and 5, the width of the tool storage cart 8 and the self-propelled cart 9 for raising and lowering tools is smaller than the entire width of the press 1, and the height is also the height of the press 1. low compared to

In operation, when replacing a press tool, as shown in FIG. 8a to the alignment position (see FIG. 2). The self-propelled trolley 9 also moves and the hook 11 is placed in the space 8 of the tool storage trolley 8.
Add 1 go to a. A cylinder 13 for opening and closing the press tool 4 and holder 3 attached to the reciprocating block 2 with a hook
and the tool storage trolley 8 by operating the hoisting wheel 16.
It is stored in the space 8a.

Next, as shown in FIG. 3, the tool storage cart 8 and the self-propelled cart 9 are moved until the new press tool 4a and holder 3a are aligned with the mounting positions on the reciprocating block 2. To attach the press tools, etc., a new press tool 4a and holder 3a are attached to the reciprocating block 2 by the reverse operation.

When performing maintenance on the reciprocating block 2 of the press machine 1, move the reciprocating block 2 to a position where it will not get in the way of lifting and lowering the reciprocating block 2 with a crane or the like (see Figures 6 and 7).
The tool storage cart 8 and self-propelled cart 9 are moved to Here, it should be understood that if the rails 7 are further extended, the tool storage cart 8 and the self-propelled cart 9 can be moved to a position that allows maintenance of the cylinder 6 of the press 1.

〔Effect of the invention〕

The hot slab width press tool changing device according to the present invention has a smaller overall size than a press machine, and since the movement between the operating position and the non-operating position is linear movement, it is possible to change the parts of the press machine. Provides sufficient space for maintenance
This maintenance work and replacement work of press tools etc. can be done safely and quickly.
