Description

[Detailed description of the invention] This invention relates to the improvement of a manipulator for forging rolls.The purpose of this invention is to reduce the sliding parts so that it can cope with the increase in size and speed required in the field of hot die forging. At the same time, by reducing the weight of the movable parts, the inertial force of the movable parts can be reduced, thereby providing an efficient manipulator of this type.

Conventionally known manipulators have many movable devices, such as a vertical movement device, a left and right movement device, a clamp device, and a tong reversing device.

Of these, the left/right moving device poses a particular problem.

The heated billet placed outside the forging roll body is transported into the roll mold by a manipulator, and from that position, the billet is moved left and right to perform the required number of roll forming steps, one pass, two passes, and three passes. However, in this case, the distance from the heated material receiving position to the roll forming position is long, resulting in large loss time.Moreover, the entire weight of a large moving device and accompanying equipment is transferred at high speed and frequently. Because of this, the sliding parts are subject to significant wear and tear, requiring periodic replacement of parts.

This invention was made to deal with the above-mentioned current situation, and its main feature is that a manipulator for material handling is attached to the roll mold of the forging roll, and the conventional left-right movement mechanism is replaced with a swing type.

This invention will be explained below with reference to embodiments shown in the drawings.
1 is the forging roll body, 2 is the forming roll mold,
Shaft 10.1 interlocked with electric motor 3 via transmission mechanisms 4 to 9
It is attached to 1.

A material receiver 13 that receives the heated material 12 is swingably supported by a support arm 14 provided on the forging roll main body 1, and is tilted as shown by the dashed line in the figure or stands upright by a drive device (not shown) to convey the material to the conveying device. The structure is such that the material 12 transported by the roll mold 2 is housed directly below the roll mold 2.

The tongs 15 for gripping the heated material are rotatably supported on a tong mount 16, and a clamping cylinder 17 supported at the upper end of the tong mount 16 is actuated to grip the material.

Further, a pinion 20 that meshes with a rack 19 connected to the reversing cylinder 18 is fitted to the upper end of the tongue 15.

Attach the bearings 23, 2 to the frame 22 with the 211Ii guide rod.
A slide 26 is loosely fitted to this via a bushing 25 so as to be able to freely slide up and down, and a lip 27 protruding from the side surface of the slide 26 and a tongue mounting base 16 are adjusted via an adjusting cylinder 28. The tong mount 16 is slid in a direction perpendicular to the sliding direction of the slide 26 when the tong mount 16 is operated.

Also, the tip of the lever 29 fitted into the guide rod 21 and the swing cylinder 3 movably supported by the frame 22
The tips of the rods 0 and 3 are connected to each other, and the tongs 15 that clamp the heated material 12 are moved from side to side in 1 pass, 2 passes, 3 passes, etc. by the operation of the cylinder 30, and the rotation thereof is regulated by a movable stopper 31 and a fixed stopper 32 provided on the frame 22.

Reference numeral 33 denotes a cylinder mounting base, which is fitted into the base of the guide rod 21 so that it cannot rotate but can slide up and down, and the lower end of the piston rod 34' of the vertically moving cylinder 34 supported by this is slid 26. The slide 26 and the device attached thereto are moved up and down by the up and down movement of the cylinder 34.

Reference numeral 35 denotes a motor with a reduction gear, which is fitted to the upper end of the guide rod 21 and supported by the motor mount 3 which is slidably fitted between the frames of the cylinder mount 33, and is connected to the cylinder via the shaft end Kid coupling 31. An adjustment screw 38 screwed into the mounting base 33 is provided.

This invention has the above structure, and its operation will be explained next.

The heating material 12 carried by a conveyor (not shown) is
The material is charged into the material receiver 13 which is tilted to a fixed position and is on standby.

Next, the material receiver 13 is raised vertically, the bushing 39 pushes up the heating material 12 into the tongs 15 from its lower end, and the clamp cylinder 17 is driven to clamp the heating material.

When the clamping is completed, the electric motor 3 is driven to rotate the roll die 2 interlocked with the electric motor 3 in the direction of the arrow, and while forming the heating material 12, the tong mounting base 16 and the tong mounting base 16 are driven by the vertical movement cylinder 34 while forming the heating material 12. The supported devices are pushed upward together with the slide 26, completing the first pass of machining.

Next, the movable stopper 31 is operated to position the lever 29 so that it stops at the 2-pass position, and after this is firmly fixed, the guide rod 21 is rotated by α by driving the swing cylinder 30, and the lever 29 is positioned so that it stops at the 2-pass position. By swinging the tongs 15 around the guide rod 21, the material is fed to the second pass.

At this time, by moving the tongs 15//'i from the 1-pass position to the 2-pass position, the tongs are shifted by X from the center position, so in the second pass, the adjustment cylinder 28 is operated to correct the tong position.

This swing operation and tong position correction operation are performed by slide 2.
6 during the descent process.

When the slide 26 reaches the lower end, the roll mold 2 is driven and a second pass of roll forming is performed, and thereafter a third pass of roll forming is performed by the same operation as described above.

When the position of the tong tip needs to be adjusted due to a change in material length or molded shape, etc., the adjusting screw 38 is rotated by the drive of the motor 35 with a reducer, and the cylinder mounting base 33 is adjusted up and down. A slide 26 connected to the piston rod 34' of the vertically moving cylinder 34. The tong position is adjusted via the tong support stand 16.

As described above, according to this invention, since the swing method is adopted for moving the material left and right, the sliding part necessary for moving the material in the left and right direction is such that the guide rod 21 moves the bearings 23 and 24 by a slight α
As a result, wear and tear on the manipulator is significantly reduced, and its lifespan can be greatly extended.

In addition, since the weight of the movable part during left-right movement is placed around the guide rod 210, the inertia during operation is reduced, making it possible to increase speed, and furthermore, the entire device becomes more compact, resulting in a significant weight reduction. There are advantages such as being able to
