Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a product take-out device in an annular metal rolling mill that rolls an annular metal material to obtain inner and outer rings of bearings and other annular metal products.

Prior Art In FIGS. 3 and 4, a rolling groove formed by a pair of inclined split rolls 41 corresponding to the shapes of the outer periphery and both side surfaces of an annular material is formed by rolling the inner periphery of a hole in an annular material 43 with a center roll. 4
2, the respective □-divided rolls 41 are rotated while contacting each other to press the outer circumference and both side surfaces of the annular material 43. The outer diameter of the annular material 43 is determined by a group of outer diameter forcing rolls 44 arranged to press into predetermined locations on the outer periphery.

Both ends of the shaft of the center roll 42 are supported by a fixed frame 46 and a movable frame 49, respectively. Radial groove 4 formed inside the fixed frame 46
5 is a holder 44 that pivotally supports the outer diameter forcing roll 44;
a is slidably supported and fixed by a bolt 48. 47 is a retainer bolt (Japanese Patent Application Publication No. 34-7408 and U.S. Patent No. 3.230.606)
issue).

After rolling, the annular material is released from the rolling groove formed by the split rolls 41 by lowering the fixed frame 46 and the movable frame 49, which are set up on an operating table 50 having a lifting means (not shown). Next, after the movable frame 49 was moved away as shown by the imaginary line, the rolled material was removed from the center roll 42 using a clamp and taken out of the machine.

Problems to be Solved by the Invention In the above-mentioned conventional method for taking out an annular product using a clamp or the like, after the movable frame 49 is moved away, the operator uses the clamp to remove the heavy annular product. The problem was that it required a considerable amount of labor to handle and remove it from the aircraft.

The present invention solves the above problem by using guide plates disposed close to both sides of the annular material to press the annular material from both sides after rolling is completed, to retract the annular material together with the movable frame in a supported state, and to introduce the material. This problem is solved by automating the process of ejecting the annular product downward at a position directly above the convexity.

Means for solving the problems The means for solving the problems of the prior art are shown in Figure 1 and 2.
Describe with diagrams.

Of the two guide plates 14a and 15 disposed close to both sides of the annular material 7, the fixed frame 12-
The guide plate 15 on the side is fixed to the tip of the pusher 13 that slidably passes through a hole 12'b provided in the fixed frame 12 supporting one end of the shaft of the center roll 8, and The guide plate 14a is fixed to a movable frame 14 supporting the other end of the shaft of the center roll 8.

The pusher 13 supporting the two guide plates 15.14a and the movable frame 14 are controlled by separate control means 1611.
7, and is configured to move in conjunction with it to the right in the figure.

A reception opening 24 for the product 7' is provided at the rightward movement position of the guide plate 14a+15 by the control means 16117.

Operation When the rolling process is completed, the bearing/advancing/retracting device 18 is operated to move the side pressure roll 2 attached to the operating shaft 4 in the direction of the arrow in the figure, and the elevating means 23 is used to move the operating table 25.
By lowering the annular product 7', the annular product 7' moves downwardly away from the rolling groove form formed by the impression roll 1 and the side pressure rolls 2.3.

Next, the control means 16 and 17 actuate the annular product 7' to the right in the drawing together with the movable frame 14 while pressing and supporting both sides of the annular product 7' with the guide plates 14a and 15, so that the annular product 7' moves into the receiving opening. 24, when the guide plate 15 on the fixed frame 12 side is moved away from the side surface of the annular product 7', the product 7
' falls into the receiving port 24.

Embodiment In FIGS. 1 and 2, an intermediate table 26 is provided on an operating table 25 having a lifting means 23 provided on a lower base 22, and a fixed frame 12 and a movable frame are mounted on the intermediate table 26. A frame 14 is erected.

Control means 16+17, such as air cylinders, are arranged on both sides of each of the frames 12 and 14 to be able to operate in conjunction with each other.

The operating table 25 moves up and down along the guide post 21, and the upper and lower ends of the guide post 21 are fixed to the upper base 20 and the lower base 22, respectively.

A bearing advancing/retracting device 18 and a driving device 19 are attached to the lower surface of the upper base 20.

A lateral pressure roll 2 is mounted on the operating shaft 4 of the advancing/retracting device 18, and a pressure roll 1 and a lateral pressure roll 3 are mounted on the drive shaft 5 of the drive device 19, so that they can be disassembled in the axial direction parallel to the axis of the center roll 8. installed. 6 is a coupling.

The pressure detection roll 1 and the side pressure rolls 2 and 3 are placed in contact with the outer circumference and both sides of the annular material 7, and the center roll 8, which is inserted through the hole in the annular material 7, is placed in contact with the inner circumference. ing.

' Behind the center roll 8, a plurality of outer diameter forcing rolls 9 that define the outer diameter of the annular material 7 are arranged so as to abut a predetermined position on the outer circumference of the annular material 7.

A holder 10 that pivotally supports the outer diameter forcing roll 9 is slidably supported in a radial groove 12a provided inside a fixed frame 12, and a bolt 27 is inserted into a long hole 12c provided along the groove 12a. Fixed by

Two guide plates 14 a + 15 arranged close to both sides of the annular material 7 act as steady rests in the axial direction of the annular material 7 during rolling.

- A push rod 13 is fixed to the guide plate 15 on the side of the fixed frame 12, which passes through a hole 12b provided in the fixed frame 12, and the push rod 13 is attached to the operating shaft 16'b of the control means 16.
It is connected to the guide plate 15 via a connecting means 16c, and is configured to be able to move forward or backward together with the guide plate 15.

The guide plate 14a on the movable frame 14 side is connected to the movable frame 14 by the fixture 14b, and the movable frame 14 is connected to the control means 1.
7 and the operating shafts 17b, respectively, and are configured to be able to move forward and backward.

Each of the guide plates 14a and 15 has a radial protrusion 140° 151L facing each gap of the outer diameter forced roll 9.
are formed respectively.

Reference numeral 24 is a receiving port provided in communication with the operating table 25 and the intermediate table 26.

Effects of the Invention According to the present invention, the conventional work of taking out an annular product was carried out by hand after the annular product was removed from the rolling groove mold formed by each roll and the retraction of the variable frame was completed. Compared to the conventional method, the annular product is automatically taken out when the movable frame completes retraction, so the time required for taking out the product is shortened, and remote control is possible without the need for an operator.
