Description

[Detailed Description of the Invention] The present invention relates to a feeding device replacement jig that enables quick replacement of a feeding device that automatically feeds a predetermined amount of material into a processing machine such as a press.

In recent years, due to the increasing abundance and diversification of products produced by press operations, and the shortening of product lifespans, high-mix, low-volume production has become more common in actual work sites.

Under such high-mix, low-volume production, it is necessary to increase the operating rate of the press in order to reduce product costs and shorten the time required for production.

In press work, in addition to performing the actual processing work using the press machine, it is necessary to carry out so-called setup work, such as transporting the dies from the die storage warehouse to the press machine, attaching and removing the dies to and from the press machine, loading the material, and adjusting the auxiliary equipment. Particularly when the processing work is changed frequently, such as in the above-mentioned high-mix low-volume production, it is extremely important in order to increase the operating rate that the time spent on setup work, which is carried out each time, be shortened.

Therefore, a mold changing device called a quick die change device was devised, which enables the installation, replacement, and positioning of molds on a press machine to be performed in a short time during the setup work mentioned above, and some of them have been put into practical use. It has become like that.

On the other hand, in press work, in addition to the press body and the mold, various auxiliary devices are used. For example, when processing coil material, there are unwinding reels, levelers, and equipment for feeding the material to the mold processing position. A feeding device is required.

When installing this type of accessory device on a press machine, it is important to align the operation center line of the accessory device, for example, the feed center line of a feed device, with the center line of the mold, to ensure accurate machining. This is important from a practical perspective.

Furthermore, with regard to the feeding device, each time the machining operation changes or the material to be fed changes, the feeding length can be adjusted, and the material can be guided from the width direction so that the material is aligned parallel to the center line of the mold. It is necessary to make fine adjustments to the feeding device itself, such as adjusting the spacing of the guide members in the width direction so that the material is fed. However, in the past, since the feeding device was fixed to the press body, it was necessary to stop the press machine in order to make the above adjustment, and the current situation was that a lot of time was wasted in this process.

Therefore, exchanging molds and expediting positioning alone are still insufficient in terms of significantly shortening setup time.

The present invention was developed in view of the above-mentioned circumstances, and involves preparing multiple feeding devices and performing various adjustments of the feeding devices in parallel while the press is in operation in preparation for the next press operation. The mounting surface of the processing machine was a bottom plate fixed to the bottom plate, an abutment plate erected parallel to the material progressing direction of the bottom plate, a side plate erected in a direction perpendicular to the abutment plate, and a side plate erected in a direction perpendicular to the fixed position of the abutment plate. a fixing member consisting of a guide pin provided on the side plate; a mounting block having a guide hole into which the guide pin is inserted and on which the feeding device is attached and fixed; and a mounting block rotatably provided on the side plate and fixed thereon; It is an object of the present invention to provide a replacement jig for a mounting device, which is configured to include a shutter member that engages the mounting block inserted into the member with a single operation.

Further, reference numeral 19 denotes a tightening screw for fixing the fixing member 1 to the bed 3, which passes through a long hole 13b drilled in a recess 13a formed in the bottom plate 13, and screws into the bed 3. It is tightened and fixed in the hole 3a.

In this case, after positioning the fixing member 1 so that the center line 0 of the fixing member 1 coincides with the center line of a mold (not shown) set on the press machine, the fixing member 1 is tightened and fixed using the tightening screws 19.

Reference numeral 2 denotes a rectangular parallelepiped-shaped mounting block on which a feeding device (not shown) is attached to the upper surface of the mounting block.
and a guide hole 2 in which the guide pin 15 is inserted almost without any gap at a position that exactly corresponds to the upright position of the guide pin 15 when the guide pin 15 is inserted while contacting the bottom plate 13.
1 is bored and a handle 22 is attached.

Further, the width W ₁ of the mounting block 2 is selected to be slightly larger than the width W ₂ of the side plate 12.

That is, the feeding device replacement jig according to the present invention includes a fixing member 1 fixed to the bed 3 side of the press machine, and a mounting block 2 to which the feeding device is attached.
The mounting block 2 is attached in advance to each of a plurality of feeding devices prepared, and the mounting block 2 is brought into contact with the fixing member 1 from the direction A in the figure using the side plate 12 and bottom plate 13 as guides. By inserting the feeder into the press machine, the feeder can be attached to and replaced with the press machine.

The state in which the mounting block 2 is inserted and fixed into the fixing member 1 is shown in FIGS. 2a to 2c.

FIG. 2a shows a plan view in this case, and FIGS. 2b and 2c show side views viewed from the direction of arrows F and G shown in FIG. 2a, respectively.

That is, the mounting block 2 is inserted into the fixing member 1 from one direction while sliding the guide pin 15 into the guide hole 21 on the bottom plate 13 surface, and the abutment surface 11 of the abutment plate 11 is
After hitting the shutter 1, loosen the screw 17 and

Further, the shutter 16 and the screw 17 are formed integrally, and each stop position of the shutter 16 in the D direction and the E direction shown in the figure and the moving distance of the shutter 16 due to the screwing operation are adjusted in advance. , the shutter 16 can be opened and closed by one operation of the screw 17.

Next, FIG. 3 shows the state in which the feeding device is mounted on the bed 3 of the press machine using the above-mentioned exchange jig.

The feeding device 31 shown in FIG. 3 is a gripper-type feeding device using compressed air as a driving source, and has a piston rod 35 and The fixed clamp part 3 is connected to the cylinder 36.
2 and a guide block 33, a movable clamp section 37 is provided which moves while being guided by a guide rod 34.

Further, the fixed clamp section 32 and the movable clamp section 37 are provided with clamp plates 32a and 37a, respectively.
A and 37a, and the material 40 is inserted between the fixed clamp part 32 and the movable clamp part 37,
For each stroke of the reciprocating movement of the movable clamp section 37, the clamp plates 32a and 3 are moved by air pressure.
7a is lowered alternately to clamp the material 40 and feed it by a predetermined amount to the processing position.

Further, 39 is a pilot valve that is operated by a pressing member attached to the ram of a press machine, for example, and generates a signal for switching the pneumatic circuit in accordance with the vertical movement of the ram.

Furthermore, although not shown, this feeding device 3
1 is provided with a feed length adjustment mechanism, a guide member adjustment mechanism for guiding the material 40 from the width direction, and the like.

Thus, the feeding device 31 having the above-described structure is attached to the upper surface of the mounting block 2. In this case, the feeding device is mounted so that the feeding centerline of the feeding device 31 coincides with the reference line of the mounting block 2, which coincides with the centerline of the fixing member 1.

Thereafter, the mounting block 2 on which the feeding device 31 is attached is slid from the side against the fixing member 1 which is fixed in advance to the bed 3 of the press machine, and is positioned using the guide pin 15 and the guide hole 21. When the end face of the mounting block 2 in the insertion direction comes into contact with the abutment surface 11a of the abutment plate 11, the shutter 1
6 and set it to the state shown in Figure 3,
The attachment of the feeding device 31 to the bed 3 of the press machine is completed.

In this case, the feed center line of the feed device 31 coincides with the center line of the fixing member, which is an extension of the center line of the mold, and since the mounting block 2 is formed in a rectangular parallelepiped shape, the material of the feed device 31 is The feeding surface and the machining surface of the mold are parallel.

Moreover, this state does not change no matter how many times the mounting block 2 is attached to and detached from the fixing member 1.

Therefore, for example, by preparing a plurality of feeding devices 31 attached to the mounting block 2, while performing one pressing operation using one feeding device 31, the feeding required for the next pressing operation can be adjusted. If the length adjustment and width guide member adjustment work is performed on other feeding devices 31, after one press operation is completed, the feeding device 31 used in this operation can be adjusted.
By removing the feeder 31 from the fixing member 1 together with the mounting block 2, and attaching another feeder 31 whose adjustment work has been completed to the fixing member 1 together with the mounting block 2, the troublesome operation of the feeder 31 when changing press operations can be avoided. This eliminates the need for adjustment work, work for feeding the material 40, etc., and enables a significant reduction in setup time.

That is, the adjustment work of the feeding device 31 can be made into an off-site setup work, and a significant improvement in the operating rate of the press machine is expected.

In particular, it is extremely effective to use a combination of the quick die change device that has been put into practical use in some places and the feeding device replacement jig of the present invention.

Furthermore, if the heights of the machined surfaces of the molds vary, it is sufficient to prepare various mounting blocks 2 having heights that match the heights of the respective machined surfaces of the molds.

In this case, the positions of the guide holes 21 relative to the mounting block 2 are set at distances l ₁ and l ₂ shown in FIG. 1b.
If the center line of the feeding device 31, which corresponds to the mounting position of the guide pin 15 that is accurately regulated and is fixed to the top surface of the mounting block 2, is aligned with the reference line of the mounting block, the material 40 relative to the mold can be This means that the feeding status of the machine can always be set accurately.

Furthermore, in the exchange jig according to the present invention, the feeding device 31 is attached and detached by sliding it from the side of the surface of the bed 3 of the press machine.
The attachment/detachment operation is extremely easy, and the workability is also extremely good.

Furthermore, the movement of the mounting block 2 on which the feeding device 31 is attached is reliably prevented by the guide pin 15 inserted into the guide hole 21, the veneer plate 11, and the side plate 12, so that the movement of the mounting block 2 to which the feeding device 31 is attached is reliably prevented. The attachment is performed reliably and firmly, and there is no fear that looseness or the like will occur in the attachment of the feeding device 31 even if press work is continued, which is effective in maintaining feeding accuracy.

Furthermore, the mounting block 2 for the fixing member 1
In order to more securely fix the mounting block 2, two or more guide pins 15 are provided on the abutment plate 11, and accordingly, two or more guide holes 21 are provided on the mounting block 2 side. Good too.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with various modifications without changing the gist thereof.

It has a guide pin erected on the abutment surface, a mounting block having a feeding device attached and fixed to the upper surface, and a guide hole that fits the guide pin, and further provided on the fixing member so that the mounting block It consists of a shutter portion to prevent the device from coming off from the fixing member.

Therefore, in the replacement jig of the present invention, it is fixed to the mounting surface so that the center line of the mold and the center line of the feeder match, and the processing surface of the mold and the feeding surface of the feeder are parallel to each other. If you fix the parts and attach the feeding device to the mounting block in advance, even if you repeatedly attach and detach the mounting block to which the feeding device is attached to the fixed member, the material will be fed to the machining surface of the mold in the correct state. For example, by preparing multiple feed devices each with a mounting block attached, various adjustments to the feed devices can be performed as external setup work separate from the actual machining work. ,
For example, it has the excellent feature of greatly improving the operating rate of press machines, and its effects are significant.

In addition, the replacement jig according to the present invention can be slid from the side parallel to the mounting surface of the feeder, while
Since the feeding device is configured to be attached and detached, it is extremely easy to replace the feeding device.In particular, even when the feeding device becomes larger, it has the advantage of being easier to replace. The effect of speeding up the process is extremely large.

Furthermore, in the replacement jig according to the present invention, the guide pin, guide hole, side plate part, and opening/closing member reliably prevent movement of the mounting block to which the feeding device is attached, so that high feeding accuracy can be maintained. Excellent effects can also be obtained in terms of performance.
