[0001]

[Industrial applications]

 The present invention relates to an oil supply device for an oil supply distributor installed on a reciprocating ram in a multi-stage homer for forming bolts and the like.

[0002]

[Prior art and its problems]

 The oil supply distributor installed on the ram distributes the supplied lubricating oil to a plurality of oil supply points such as the sliding surface of the ram. A flexible oil supply pipe (hose) was directly connected to the distributor for oil supply. Therefore, the refueling pipe swings back and forth as the refueling distributor moves back and forth together with the ram, but the ram reciprocates at a high speed of about 350 times per minute. The oil supply pipes that are swung at the same speed have a short service life even if they are sufficiently strong, and there is a problem in that the work must be interrupted due to sudden damage during the work.

Has been done. Reference numeral 12 is a substantially horizontal front-rear direction link, the outer end of which is pivotally supported on the upper end of the swing rod 9 by a horizontal support shaft 13 and the inner end of which is the rear of the ram 2. The rear end of the extending portion 2a is pivotally supported by a bearing member 14 and a horizontal support shaft 15 in the horizontal direction. Reference numeral 16 denotes an oil supply distributor installed on the rearward extending portion 2a of the ram 2. Each oil supply port has a sliding surface between the slide rails 4a, 4b and the slide guides 5a, 5b. Are connected to pipes 17a, 17b ...

As shown in FIGS. 2 and 3, the swing rod 9 is made of a pipe material, and has an oil supply passage 18 extending over the entire length therein. At both ends of the swing rod 9, cylindrical bearings 19 and 20 which are fitted on the support shafts 11 and 13 so as to be rotatable only are fixed in a right angle direction. Radial openings 21 and 22 communicating with both ends of the oil supply passage 18 in the swing rod 9 are formed. The support shaft 11 is supported by the pair of left and right bearing members 10 located outside the tubular bearing 19, and is positioned and fixed by nuts 23 and 24 screwed into both ends. Further, oil-tight seals 25 are interposed between the cylindrical bearing 19 and the left and right sides of the opening 21, and one end of the shaft 11 is opened at one end of the shaft 11. An oil supply passage 26 is formed at the other end of the cylindrical bearing 19, which can be opposed to the opening 21 of the cylindrical bearing 19. Further, an oil supply pipe 27 is connected to one end of the support shaft 11 so as to communicate with the oil supply passage 26 via a pipe connector 27a that is screwed into one end screw hole of the oil supply passage 26.

The support shaft 13 is supported by the pair of left and right links 12 located outside the tubular bearing 20, and is fixedly positioned by nuts 28 and 29 screwed into both ends. In addition, oil-tight seals 30 are interposed between the cylindrical bearing 20 and the left and right sides of the opening 22. One end of the oil-proof seal 13 opens at one end of the support shaft 13 and An oil supply passage 31 having an opening at the other end is formed on the peripheral surface of the tubular bearing 20 that can face the opening 22 of the tubular bearing 20. Further, an oil supply pipe 32 is connected to one end of the support shaft 13 so as to communicate with the oil supply passage 31 via a pipe connector 32 a screwed into a screw hole portion at one end of the oil supply passage 31.

A flexible hose is used as the oil supply pipe 32, and the other end thereof is connected to the oil supply port of the oil supply distributor 16 as shown in FIG. In FIG. 3, reference numeral 33 is a connecting tool for connecting and integrating the pair of left and right links 12 with each other.

In the homer having the above-described structure, the ram 2 is reciprocally moved in the front-rear direction via the crank arm 8 by the revolution movement of the crank pin 6, and the punch attached to the ram 2 and the die attached to the fixed base 1 described above. The workpiece is pressed between the ram 2 and the ram 2. The upper end of the swing rod 9 is pushed and pulled back and forth through the link 12 by the reciprocating movement of the ram 2 in the front-rear direction. The swing rod 9 swings back and forth around the support shaft 11 in synchronism with the reciprocating movement of 2. When the swing rod 9 swings back and forth, the cylindrical bearings 19 and 20 at both ends perform forward and reverse rotational movements about the support shafts 11 and 13. If the openings 21 and 22 to be formed and the end openings of the oil supply passages 26 and 31 in the support shafts 11 and 13 on the openings 21 and 22 side have appropriate circumferential lengths, the swaying will occur. Even if the tubular members 19 and 20 rotate forward and backward with respect to the support shafts 11 and 13 as the movable rod 9 swings back and forth, the oil supply passages 26 and 31 in the support shafts 11 and 13 and the swing rods. The oil supply passage 18 in 9 can always be communicated with each other through the openings 21 and 22 of the cylindrical bearings 19 and 20.

However, when the lubricating oil is supplied from the oil supply pipe 27 connected to the support shaft 11, the lubricating oil is supplied to the oil supply passage 26 in the support shaft 11, the opening 21 in the tubular bearing 19, the swing rod. 9 through the oil supply passage 18 in the cylindrical member 20, the opening 22 in the tubular member 20, the oil supply passage 31 in the support shaft 13, and the oil supply pipe 32 to the oil supply distributor 16 on the ram 2 side that reciprocates. The oil is supplied and distributed and lubricated from the pipes 17a, 17b.

Since the entire oil supply pipe 32 only reciprocates back and forth integrally with the ram 2, a large repetitive bending force does not act. Further, the end portion of the oil supply pipe 32 on the side of the support shaft 13 moves slightly up and down with the back-and-forth swinging motion of the swing rod 9. In order to prevent it from being received, an oil supply passage is provided in the link 12 as in the swing rod 9, and an oil supply passage is also provided in the support shaft 15 as in the support shaft 13. The oil supply passages 26 and 31 of the rocking rod 9 and the oil supply passages 18 of the rocking rod 9 are communicated with each other. The oil supply pipe 32 may be connected to the oil supply passage in the support shaft 15. In this case, a metal pipe can be used as the oil supply pipe 32.

[0012]

[Operation and effect of the device]

 As described above, according to the homer's oil supply device of the present invention, the oil supply passage in the rocking rod which makes a reciprocating rocking motion in conjunction with the ram and the oil supply passages in the support shafts at both ends of the rocking rod are provided. Since it is configured to supply the lubricating oil from the oil supply pipe to the oil distribution distributor installed on the ram, the conventional structure was to receive a large repetitive bending force due to the high speed motion of the ram. Of the flexible oil supply pipe is replaced with the oil supply passage in the swing rod, and the oil supply passage in the upper support shaft of the swing rod and the oil supply distributor on the ram Even if an oil supply pipe composed of a flexible hose is used in the above, the entire oil supply pipe only reciprocates back and forth integrally with the ram and does not receive a large repetitive bending force.

[0013] Therefore, the service life of the lubrication passage constituent members to the lubrication distributor on the ram is significantly extended, and maintenance work costs such as periodic hose replacement can be significantly reduced, Almost no inconvenience such as work interruption due to damage to the hose is eliminated.
