Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention comprises a brick tooling die tooling set including an upper plunger and a lower plunger, which is attached to and detached from a die holder, and an attaching and detaching device which attaches and detaches the die tooling set to a die exchanging transfer carriage and a raw material supply device. Brick forming press.

[0002]

[Prior art and its problems]

 Generally, for example, a brick-forming press equipped with a device that rationalizes the process such as easy and short-time exchange of a mold has been known, and for example, the applicant of the present invention has published JP-B-61-49085. It is disclosed in the gazette and the like. This is a technology for maintaining a high vacuum and unmanning the brick molding operation in a vacuum brick molding machine. In addition, the proposal of Japanese Patent Application No. 2-402005, which is the invention of the previous application, was proposed on the 1st. This is a technology for exchanging the die, ie, the die tooling set, and the raw material in a short time in response to frequent die exchanges several times, or changes in the die and the raw material. Refer to FIG. Explain.

A mold 28 having upper and lower plungers 26 and 27 is transferred to the front surface of the press by a transfer carriage 29 for mold replacement, and set in a mold holder 25 by a mold withdrawing cylinder 34. Further, since the transfer carriage 30 provided with the raw material charger 32, the hopper 31, and the charger cylinder 33 is provided so as to be able to laterally transfer on the rear surface of the press 41, a plurality of transfer materials in which different raw materials are accommodated in the hopper 21 are provided. The raw materials can be changed in a short time by providing the carriages 30, 30, ... And replacing the transfer carriage.

However, in the above technique, since the plurality of transfer carriages 30 having a fixed height are provided, the die holder 25 is fixed to the press 1, and the upper and lower pressurizing pistons P1 and P2 pressurize the die holder 25. Limited to the type of press. Therefore, the above technique cannot be applied to a hydraulic or screw type die floating type press in which the die holder 25 moves up and down.

[0005]

[Problems to be solved by the device]

 The present invention, in a die floating type press in which the die holder moves up and down and is pressure-formed only by the upper plunger of the press body, as in the case of die exchange, bricks that can easily exchange raw materials in a short time. The purpose is to provide a molding press.

[0006]

[Means for Solving the Problems]

 According to the present invention, a brick forming die tooling set having an upper plunger and a lower plunger is attached to and detached from a die holder, and the die attaching and detaching device is attached to and detached from a die exchanging transfer carriage and a raw material supply device. A plurality of transfer carriages, the raw material supply device, the moving means for moving the raw material supply device back and forth, and the raising and lowering means for moving the raw material supply device up and down. And a positioning pin for positioning the mold holder.

The lifting means is preferably a pantabluff type that operates hydraulically.

Further, it is preferable that the moving means is a dolly operated by hydraulic pressure.

[0009]

[Explanation of effects]

 When exchanging raw materials in the die floating type press configured as described above, the clamp is released on the transfer carriage, the raw material supply device is retracted, the positioning pin is removed, and the transfer carriage is moved in the lateral direction to replace it beforehand. The work can be started immediately by moving the transfer trolley prepared with the raw material to the rear of the press, aligning the height with the die holder by the elevating means, advancing the raw material supply device, positioning with the positioning pin and clamping. .. Since the raw material supply device moves up and down together with the mold holder by the elevating means, it does not hinder the pressing work. Further, since the mold attaching / detaching device is fixed to the mold holder, there is no hindrance to the operation.

【Example】

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

In FIGS. 1 and 2, the press body 1 is provided with an upper piston 2 and a mold holder 3 supported by a plurality of cylinders 4 and 4 so as to be vertically movable. Further, a mold drawing cylinder 5 is fixed to the mold holder 3. Then, the die exchanging transfer cart 9 holding the die 8 which is the die tooling set including the upper plunger 6 and the lower plunger 7 is mounted on the rails 10 provided on the front side of the press body 1. It is provided so that it can run freely.

A transfer carriage 12 is movably provided on rails 11 provided on the rear side of the press body 1. A carriage 13 is movably provided by a cylinder 14 on rails 15 and 15 provided on a floor 16 of the transfer carriage in a direction perpendicular to the rail 11. Further, the carriage 13 is provided with a charger frame 18 via a lifting device 17 (a pantograph type in the illustrated example), and the charger frame 18 is provided with a charger 19 and a charger cylinder 20. There is. The hopper 21 provided with the feeder 22 is fixed to the transfer carriage 12. Further, the charger frame 18 is provided with a positioning pin 23 and a clamp device 24.

Therefore, when exchanging the raw material, the clamp device 24 is released, the cylinder 14 is operated to retract the carriage 13 from the press body 1 (see FIG. 2), and the transfer carriage 12 is moved along the rail 11. A transfer carriage 12a (not shown) containing another raw material prepared in advance is moved to the rear surface of the press body 1, and the lifting device 17 adjusts the height to the mold holder 3 and operates the cylinder 14 to move the carriage 13. If it is advanced and positioned by the positioning pin 23 and clamped by the clamp device 24, the press work with the replaced raw material can be started.

In addition, when exchanging the die tooling set, that is, the die 8, the cylinders 4 and 4 for raising and lowering the die holder 3 are operated to move the die holder 3 to the die exchanging transfer carriage 9. The mold drawing cylinder 5 may be operated while adjusting the heights.

[0015]

[Effect of the device]

 Since the present invention is configured as described above, even in the die floating type press in which pressure molding is performed only by the upper plunger, the transfer carriage charged with the raw material can be easily replaced, so that the mold can be replaced. Similar to, the raw materials can be exchanged easily and in a short time.
