Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rolling device having a pair of dies, a bolster, and a carrier slide.

In conventional rolling processing equipment, when an attempt is made to stop the pair of left and right carrier slides at a neutral point, stop the hydraulic pump, and change the bolster, the carrier slides are driven by a hydraulic cylinder, and the left and right carrier slides are driven by a hydraulic cylinder. Due to the structure of the slides, there is a difference in weight, so the heavier carrier slide gradually falls downward, causing the two bolsters to fall.
It was difficult to change the setup by making one set of sheets.

The present invention provides a stopper device that holds the carrier slide at a neutral point during the setup change of the bolster in the rolling processing equipment, and prevents the carrier slide from slipping off. An embodiment of the present invention will be described with reference to the drawings.

FIG. 1A is a front view of the entire device showing the inside by cutting away the right side of the figure from the center dot-dash line, and FIG. 1B is a schematic top view of the device.

In the figure, a denotes the main body of the machine, which consists of a substantially rectangular frame, and is provided with a carrier slide 1, which will be described later, as shown in FIG. 1B.

That is, a pair of left and right carrier slides 1 have a bolster 6 and a mold T attached to their front surfaces, and are moved by hydraulic cylinders 2 in opposite directions.

A pinion gear 3 synchronizes the movement of the carrier slide 1, and meshes with a rack (not shown) provided on the carrier slide 1.

4 is a roller that supports the carrier slide 1 from the back side.

5 is a stopper device which will be described later, and 31 is a workpiece.

FIG. 2 is a detailed explanatory diagram of the stopper device 5. A frame 13 is attached to the machine body a, and the hydraulic cylinder 9 and the guide 11 are supported by the frame 13.

The stopper rod 8 is connected to the piston rod of the cylinder 9 by a screw IOK, and moves in the left-right direction in a guide jacket 12 housed in the guide 11.

The tip 11 of this stopper rod 8 has a cylindrical shape,
Further, a hole 16 having an inner diameter larger than the outer diameter of the tip IT is bored in the back surface of the carrier slide 1, and when the tip 11 is inserted into the hole 16, the carrier slide 1 can move in the vertical direction. to regulate.

Reference numeral 14 is a limit switch rod fixed to the stopper rod 8, which integrally holds a limit switch dog 15, so that the left and right movement of the stopper rod 8 can be detected by the limit switch. .

3 and 4 show the structure of the mounting of the bolster 6 to the carrier slide 1 shown in FIG. A block 20 that contacts the tapered surface 18 and determines the vertical position is a bolster tightening mechanism at the upper end of the bolster 6, and a bolt 21 is inserted into the notch 22 (see FIG. 4) on the bolster 6 and tightened. and the notch 23 (see FIG. 3) of the bolster 6 are simultaneously pushed downward and fixed.

Reference numeral 24 shown in FIG. 4 is a keyway on the back side of the bolster 6, and the position of the bolster 6 in the left and right direction is determined by a key 25 provided on the carrier slide 1.

FIG. 5 is an explanatory diagram of a method for changing the setup of the bolster 6.

First, the carrier slide 1 is stopped near the neutral point, and the aforementioned stopper device 5 is activated, that is, the hydraulic cylinder 9 shown in FIG. .

Completion of this insertion can be confirmed by operating a limit switch (not shown) using the iron 14 and dog 15 in FIG.

When the insertion is completed in this way, the hydraulic pump (not shown) provided in the machine body a stops, so the carrier slide 1 also stops, but due to its mechanism, the right one, which is heavier, is stopped. It begins to slide downward,
The one on the left is synchronized with the one on the right by the rank and pinion gear 3, so it starts to move upward, but since the stopper device 5 is working, the hole 16 and the stomperon 8
The movement is only allowed by the play of the tip 17 of.

Adjustment is made so that the point at which this sliding down and upward movement is completed becomes the neutral point of the left and right carrier slides 1.

Next, the left and right bolsters 6 are integrated by inserting the pin 21 into the hanging tool 26, as shown in FIG.
A hook 28 allows it to be hung from a crane (not shown) for removal and installation.

First, to explain the installation, the left and right bolsters 6 integrated as described above are hung by a crane and lowered between the left and right carrier slides 10.

At this time, a jig 29 using the T-groove 30 on the bolster 6 is used so that the distance between the lower sides of both the bolsters 6 is the same as the upper distance.

When both the bolsters 6 are lowered, the key 25 and the keyway 24 shown in FIG.

When both the bolsters 6 are further lowered, the tapered surfaces of the block 19 and the tapered surfaces 18 of both the bolsters 6 come into contact with each other at the same time, and the lowering is completed.

Here, each bolster 6 is fixed using the fixing mechanism shown in FIGS. 3 and 4, and then the hanging tool 26 and the jig 29 are removed from the bolster 6, thereby completing the installation.

Note that the removal of the bolster 6 is the reverse of the above-mentioned installation procedure.

In the above setup change, if the stopper device 5 according to the present invention was not provided, the right carrier slide 1 would slip down and the left carrier slide 1 would move upward, as shown by the broken line in FIG. Due to the movement, the position of the block 19 becomes out of order (as a result, it becomes impossible to unfasten the right and left integrated bolsters 6, and therefore it becomes impossible to change the setup by integrating two bolsters 60. There is an inconvenience in that it has to be replaced one by one.

In this way, the present invention has a stopper device 5 that holds both carrier slides 1 at the neutral point when changing the bolster 60.
As a result, the pair of right and left bolsters 6 can be attached and detached at the same time as one set, and the time required for changeover can be significantly reduced compared to the conventional case where one of the left and right is attached and detached separately.

Moreover, the stopper device 5 has its stopper rond 8
The main parts such as are provided on the machine body a, and only the hole 16 is on the carrier slide 1.
There is no problem during normal operation of the rolling equipment.
