Description

[Detailed Description of the Invention] The present invention relates to a cold forging slag feeding device used for feeding slag, which is a cylindrical material, to a mechanical press.

The slag fed into the material feeding device is transported by a stock conveyor, from an orientation feeder, through a chute and alignment device, and then delivered to the feed bar of the transfer of the mechanical press and fed to the mold, but from the chute to the feed bar. Various types of feeding devices are required depending on the shape of the slag, and the development of such devices is desired.

An object of the present invention is to provide a slag feeding device for cold forging that can reliably feed slag in a cylindrical shape or a similar shape, has a relatively simple structure, and is easy to handle. Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, the overall arrangement of a mechanical press 1 is shown with a material feeding device installed adjacently. The slag fed into the material feeding device 3 is conveyed by the stock conveyor 4, goes up, goes down the switching duct 5, the cylindrical slag enters the first orientation feeder 6, and then goes up again to the pipe chute 7.
, descends and slides through the slug aligning device 8 to the feeding device 11 . The flat slug, which is relatively low in height and large in diameter, descends from the switching duct 5 to the second orientation feeder 9, rises from there, enters the flat chute 10, slides, and passes through another feeder provided at its tip. It is delivered to the feed bar 2 by the feeding device. The slag is lifted by a conveyor as it ascends, and slides under its own weight as it descends.

2 to 6, each part of the feeding device 11 is shown.

The chute 12 guides the slug 13 and has an inclination such that the slug 13 slides under its own weight. A rotatable pawl 14 for stopping the most advanced slug 13 is provided near the outlet of the chute 12. The claw 14 is rotated around the fulcrum pin 15b by the cylinder device 15 and the arm 15a, and is caused to protrude and retract into the passage of the slug 13 of the chute 12. Further, a holding member 16 is provided at the tip of the piston rod of the cylinder device 17 for holding down and stopping the next slug 13 following the most advanced slug 13. Pressing member 1
6 can be raised and lowered freely, and when raised, the slug 13 is released and the chute 12 slides. A rotary chute 18 is provided in the vicinity of exiting the chute 12 so as to be rotatable around a fulcrum pin 19, and in the rotated position (indicated by the dashed line) due to the biasing force of the spring 20, the center of the rotary chute 18 is located at the chute. It faces almost in a straight line with the center of the slug 13 guided by the slug 12. When the rotating chute 18 receives and accommodates the sliding slug 13, it rotates and stands up due to the weight of the slug 13.

A passage prevention plate 21 is provided to prevent the slug 13 from passing through the rotary chute 18 during the rising process. At the bottom of the rotating chute 18 is a slug 13.
A pusher device 22 is provided for moving the object a certain distance. The pusher device 22 includes a cylinder 22a.
is provided, allowing the pusher 23 to move forward and backward. When the pusher 23 returns, the push rod 24 fixed to the pusher 23 pushes the lower part of the rotary chute 18, and the rotary chute 18 quickly stands up to an accurate posture. At this time, the slug 13 accommodated in the rotating chute 18 falls into the pusher 23.

The pusher 23 moves forward along the guide rod 22 while being driven by the cylinder 22a, and stops above the hole in the receiving member 25 provided at a fixed position. Pushya 2
The slug 13 moved by 3 falls into the receiving member 25. The slug 13 is transferred from the receiving member 25 to the feed bar 2.

Next, we will discuss the effect. When feeding the slag, a presser member 16 provided on the chute 12 is used to feed the slag.
Hold down the first slug 13, rotate the claw 14 by operating the cylinder device 15, and press the first slug 13.
release. Next, the claw 14 is brought out into the slag passage and the holding member 16 is raised. Repeat this operation below. The slug 13 released from the claw 14 enters the rotary chute 18 and raises the rotary chute 18. When the pusher 23 returns, the push rod 24 is used to accurately raise the rotary chute 18, and the slug 13 is inserted into the pusher 23. When the pusher 23 moves to the forward end, the slug 13 falls into the hole of the receiving member 25 at a fixed position, and is delivered to the feed bar 2 from here. When the pusher 23 moves forward, the rotating chute 18 is moved toward the chute 12 by the biasing force of the spring 20.
Directed towards the entrance. The movements of the pawl 14, presser member 16, and pusher 23 are synchronized with the movement of the feed bar 2, so that the slug is fed smoothly.

As is clear from the above description, according to the present invention, it is possible to reliably feed slugs in cylindrical or similar shapes, the structure is relatively simple and easy to handle, and the movement of each part is controlled electrically. The practical effects and advantages are extremely large, such as the fact that automation is easily possible if synchronized.
