[0002]

2. Description of the Related Art Conventionally, as a method of exchanging dies for, for example, a punching press, a method is generally employed in which an operator exchanges every one dies. In addition, a plurality of molds (2
(5 types)) A system is adopted in which the units are exchanged for each unit.

[0003]

However, in the above-described conventional die changing method in the punching press, it is impossible to properly arrange the dies according to the shape of the work. In such a case, a great deal of time is required for replacement. Also, when replacing the molds in units, the molds are made up of 5 molds at the maximum.
When a mold or more is used, two or three replacements are required during the processing of one product, and the tact time is increased.

Further, since there is only one mold block used in the turret punch press, external setup cannot be performed, and there is a problem that the machining time is reduced by the mold exchange time.

[0005] The object of the present invention is to make the mold alone or replaceable as a unit, so that the mold arrangement can be optimized and the mold for the next rod can also be set up externally, thereby shortening the stopping time of the processing machine. An object of the present invention is to provide a die changing device in a punching press.

And a single die exchange station for positioning the die block and exchanging the dies adjacent to the single punch exchange station.

According to a third aspect of the present invention, there is provided a die changing apparatus for a punching press according to the present invention, comprising a punch block frame provided with a punch block having a plurality of punches in a longitudinal direction of the frame, and a plurality of dies. A movable body having a die block frame provided with a die block is movably provided, a ram carrier is movably provided in the punch block frame in a longitudinal direction of the frame, and a punch and a die are cooperated with the ram carrier. A ram cylinder is provided for operating the ram cylinder, the ram cylinder is provided movably in a direction orthogonal to the longitudinal direction of the frame, and a punching press having a work positioning device for positioning a work is provided. Engage with the punch block and the die block adjacent to the replacement position A transport vehicle having a detachable chuck device is movably provided on a traveling path, and both a punch block and a die block are accommodated in the traveling path adjacent to the mold exchanging position, and a standby state for storing is performed. A station is provided, a block unit exchange device having a plurality of storage areas is provided in the storage standby station, and the punch block is detached from the die block adjacent to the storage standby station to position the punch block and perform punch exchange. An exchange station is provided, and a single die exchange station for positioning a die block and exchanging dies is provided adjacent to the single punch exchange station.

According to the die changing device in the punching press according to the first, second, and third aspects, the punch and the die can be changed one by one and can be changed in units of blocks, so that the stop time of the processing machine can be reduced. In addition, the exchange of a single punch and die can be simplified, and the mold arrangement can be optimized and the next rod mold can be set up.

In the state described above, the clamp is released, the punch block 15 and the die block 62 are taken out, and a new punch 13 to be used next is inserted into the punch block 15.
Then, the new die 61 is replaced with the die block 62. At this time, there is no space above the single die exchange station 53, and there is an advantage that the work can be performed easily.

When the replacement operation is completed, the new die block 62 is transported by the transport wagon 45 to a position immediately below the punch block 15 mounted on the single-punch replacement station 51, and is transferred together with the punch block 15 to the shot pins 157 and the clamp members 153A and 153B. And fix it. Then, the punch 13 and the die 61 are aligned with each other.
There is only a rail member 39 under the space, so that there is sufficient space, and it is easy for humans to enter the work. After the centering, the die 61 is fixed to the die block 62. The structure for fixing the die 61 is already known and is the same as that conventionally used in a punching press, so illustration and description are omitted. I do.

Next, the lower end provided on the elevator box 149 is aligned with the traveling path 35, and the punch block 15 and the die block 62 are chucked by the chuck device 121 provided on the carrier 45. Then, while releasing the shot pin 157, the clamp is released by the operation of the clamp members 153A and 153B, and the punch block 15 and the die block 62 are accommodated in the lower stage of the elevator box 149.

The elevator box 149 is returned to the lowermost limit and one cycle is completed. If there is no need to replace the punch block 15 and the die block 62, the used punch block 15 and the die block 62 may be put on standby while housed in an elevator box 149 as a housing box.

As described above, when the entire block is replaced, the stop time of the processing machine can be remarkably reduced, and the single punch exchange station 51 also serves as a setting station for aligning the punch 13 and the die 61. The operation rate of the processing machine can be improved. In addition, the die arrangement can be optimized and the die for the next rod can be set up outside, and the punch block 15 and the die block 62 can be easily and easily replaced independently. The present invention is not limited to the above-described embodiments of the present invention, but can be embodied in other modes by making appropriate changes. In the above-described embodiment, an example is described in which the accommodation standby station 47 has an accommodation area in the up-down direction. However, an accommodation area may be provided in the left-right direction, and the accommodation box may be moved in the left-right direction.

[0067]

As will be understood from the above description of the embodiments, according to the present invention according to the first, second and third aspects, the die changing device provided adjacent to the punching press is provided with a punching press. In addition, a block unit changing device was provided in the storage standby station near the die changing position, and a single punch exchanging station was provided adjacent to the block changing device. Further, a single die exchanging station is provided adjacent to the single punch exchanging station, and a punch block equipped with a punch and a die block equipped with a die are moved to each station by a carrier equipped with a chuck device, and the punch, Pull out the die and replace it.

Thus, the replacement can be simplified, the time required for the replacement can be shortened, the operation rate of the processing machine can be improved, and the arrangement of the dies can be optimized and the dies for the next rod can be set up by the external setup. can do.

According to the fourth aspect of the present invention, the block standby unit is provided with a block unit changing device, and a punch block and a die having a punch to be used next are provided in a vertically arranged receiving area. Since the die blocks are housed in pairs, the mold can be exchanged in a shorter time than in the conventional case. Moreover, since the storage standby station is provided in the vertical direction, space can be saved.
