Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a split type carrier on which a die of a transfer press apparatus using a crossbar is mounted.

[Prior Art] As shown in FIGS. 4 and 5, a die 2 of a transfer press using a conventional crossbar 1 is mounted on a die exchange carrier 4 via an expansion bolster 3, and the die 2 When exchanging, the crossbar 1 is detached from the transfer press, and the crossbar 1 is supported on a crossbar cradle 5 provided on the carrier 4 so as to be tiltable about an axis parallel to the rail 6, The mold exchange carrier 4 was moved on the rail 6 by a required distance from the pressing device and pulled out, and then the mold 2 was exchanged using a crane or the like.

[Problems to be Solved by the Invention] However, when the mold exchanging carrier 4 is moved from the press device by a required distance and pulled out, and when the mold 2 is exchanged, the space between the molds 2 mounted on the mold exchanging carrier 4 is reduced. Mold 2 because it is narrow
Is difficult to attach / detach, and when the die 2 is attached / detached using a crane or the like, the die 2 comes into contact with the crossbar 1 due to the deflection of the wire that suspends the die 2, damaging the crossbar 1, or the die 2 There was a risk that an operator who would replace the above would be caught between the mold 2 and the crossbar 1.

The present invention solves the above-mentioned problems, and provides a split type carrier that can easily perform the die exchange by drawing the die exchange carrier and then dividing the die exchange carrier to leave a space between the dies. Is intended.

[Means for Solving the Problems] The present invention relates to a transfer press apparatus using a crossbar, which is a die exchange carrier including end carriers and intermediate carriers that can move in a direction perpendicular to a work advancing direction. The end carrier is releasably connected to the intermediate carrier so that the end carrier can move in a direction perpendicular to the work advancing direction by a required distance in parallel with the work advancing direction.

[Operation] Therefore, after moving the mold exchanging carrier by a required distance in the direction perpendicular to the work advancing direction from the pressing device, each end carrier is separated from the intermediate carrier in a direction parallel to the work advancing direction.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 to 3 show an embodiment of the present invention, in which a set of rails 6 provided at right angles to the work advancing direction of a transfer press is provided with wheels 7 and wheels 9 driven by a drive device 8. The middle part carrier 10 and the end part carrier 1 are arranged so that the die exchange carriers 4 run by
Divided into 1, 12 and end carrier 11, 12 middle carrier 1
A nut 13 and a reverse screw nut 14 are provided inside the end surface adjacent to 0, respectively, and a screw shaft 15 penetrating the intermediate carrier 10 and rotatably attached to the intermediate carrier 10.
, The nut 13 and the reverse screw nut 14 are screwed together, and a drive device 16 for driving the screw shaft 15 is provided inside the intermediate carrier 10, and the end carriers 11 and 12 and the intermediate carrier 10 are detachably connected. The drive shaft 17 of the wheel 9 is connected by an expansion joint 18. A groove 19 is provided in a direction perpendicular to the rail 6 at a position where the mold exchange carrier 4 including the intermediate carrier 10 and the end carriers 11 and 12 has moved the rail 6 by a required distance, and the groove 19 is formed at a right angle to the rail 6. A rail 20 is installed on a rail 19 so that the upper surface of the rail 20 can be raised and lowered via a jack 21 so that the upper surface of the rail 20 can be projected and recessed from the upper surface of the rail 6, and the end carriers 11, 12 run on the rail 20. A wheel 22 is provided so that the mold changing carrier 4 is installed in a hole 24 provided on the floor surface for supporting the intermediate carrier 10 when the intermediate carrier 10 and the end carriers 11 and 12 are divided. To do.

Further, a crossbar pedestal 5 for supporting the detached crossbar is pivotally mounted on each carrier so as to be tiltable by a cylinder 25.

Since it is configured as described above, when replacing the mold 2,
Crossbar 1 from transfer press not shown
Is removed and supported on the crossbar cradle 5, and the drive unit 8 drives the wheels 9 to drive the intermediate carrier 10 and the end carrier.
The mold exchange carrier 4 consisting of 11, 12 is moved to the mold exchange carrier pull-out position which is moved on the rail 6 by a required distance.

Next, the jack 23 is extended and the lower surface of the intermediate carrier 10 is pushed up so that the mold exchanging carrier 4 is entirely covered by the wheels 7 and 9 on the rails 6.
And the jack 21 is extended to raise the rail 20 until the upper surface of the rail 20 projects from the upper surface of the rail 6 and contacts the wheel 22.

When the wheels 22 come into contact with the rail 20 and the end carriers 11 and 12 are ready to run on the rail 20, the driving device 16 drives the screw shaft 15 to drive the end carriers 11 and 12.
Is moved away from the intermediate carrier 10 as shown by arrow A in FIG. 1 to operate the cylinder 25 to tilt the crossbar pedestal 5 and replace the mold 2 on the bolster 3.

When the replacement of the mold 2 is completed, the cylinder 25 is operated to erect the crossbar pedestal 5, and the screw shaft 15
Drive the end carriers 11 and 12 into the intermediate carrier 10 as shown in FIG. 1 by the arrow B side to retract the jacks 23 and 21 so that the mold changing carrier 4 can run on the rail 6. The mold exchange carrier 4 is run on the rails 6 and drawn into the press machine, and the crossbar 1 is mounted on the transfer press.

It should be noted that the present invention is not limited to the above-described embodiments, but increases the number of rails forming each track, uses gear drive for tilting the cradle of the crossbar, and the intermediate carrier and It is needless to say that a gear drive, a cylinder or the like is used for the end carrier separating / engaging device, and various changes can be made without departing from the scope of the present invention.

[Advantage of the Invention] As described above, according to the split mold carrier of the present invention, the space between the molds is widened by dividing the carrier when the molds are replaced, so that the mold replacement is quick and easy. It is possible to obtain the excellent effect of preventing damage to the crossbar due to contact with the mold and a risk of an operator being caught between the mold and the crossbar.
