A clamping device for an ingot processing.

Ingots are generally solidified by melting a metal or alloy once and then pouring it into a mold, which refers to a metal mass hardened in a form suitable for processing or remelting such as rolling or forging.

Such ingots are formed into steel pieces such as billets, which are usually materials for rolling and forging, before being processed into plastic processing such as forging, rolling, and extrusion. In other words, the ingot is pressed or ground to form a billet which is a material for rolling and forging a steel.

As such, in order to form a billet, the ingot must be moved at various angles and placed in a work space in the upper and lower presses. In the related art, a worker manually lifts an ingot and places the ingot in a work space inside the press. The billet was formed by driving.

However, in the conventional ingot forming process, since the operator has to lift the ingot directly to the inside of the press, there is a risk of causing a fatal injury to the operator due to the press processed at high pressure and high speed when the press malfunctions.

Moreover, due to the nature of the manual work of the worker lifting the ingot as described above, it is necessary to repeatedly transport relatively heavy ingots, and thus, industrial accidents such as musculoskeletal disorders such as waist, knee, and shoulder frequently occur due to excessive transfer work.

Referring to the operation and effect of the present invention configured as described in detail as follows.

The clamping device for processing ingot of the present invention clamps the ingot so as to settle the ingot in the working space of the processing apparatus such as the press P or move the clamped ingot freely inside the press P.

2A and 2B illustrate an operating state in which the arm 210 including the clamp device portion is lifted or lowered as a whole while the ingot is clamped, and a tilting cylinder coupled to the support plate 110 to raise and lower the ingot. The ingot is raised and lowered by rotating the tilting lever 140 through 120.

That is, when the ingot is to be lifted upward as shown in FIG. 2A, when the rod 125 of the tilting cylinder 120 is driven to pull down the tilting link 130 coupled with the rod 125, the tilting is performed. One end of the tilting lever 140 coupled with the link 130 is lowered together in the downward direction, and the other end of the tilting lever 140 can be lifted upward by the principle of the lever.

On the other hand, when the ingot is to be lowered as shown in FIG. 2B, the tilting link 130 coupled with the rod 125 is raised upward as opposed to the operating state of the tilting cylinder 120 described above. Then, one end of the tilting lever 140 coupled with the tilting link 130 is raised together in the upward direction while being able to lower the other end of the tilting lever 140 by the principle of the lever.

Here, the tilting lever 140, the horizontal adjustment lever 150 is rotatably coupled to the support plate 110 and the connecting plate 200, respectively, by horizontally arm 210 configured to be coupled to the connecting plate 200 It can be raised or lowered in a state, which is to raise or lower the sliding unit and the clamping unit connected to the arm 210 in a horizontal state.

In addition, in order to transfer the ingot coupled to the finger part before and after, the saddle 320 is moved forward and backward along the guide rail 310 to transfer the clamping device part.

That is, in order to transfer the ingot to the front, as shown in Figure 3a, by turning the handle 385 to rotate the feed screw 380, thereby the feed screw 380 in the screw guide groove formed in the fixed block 360 The saddle 320 is moved forward while being guided and moved forward.

Then, since the guide groove 325 formed in the saddle 320 is fitted to the guide rail 310 coupled to the guide frame 300, the saddle 320 slides forward along the guide rail 310. While being made, the clamping device portion coupled with the saddle 320 is smoothly forwarded, thereby transferring the ingot coupled to the clamping device portion forward.

On the other hand, if you want to convey the ingot to the rear as shown in Figure 3b, by turning the handle 385 in the opposite direction to rotate the feed screw 380, thereby the feed screw 380 to the fixed block 360 The saddle 320 is moved backward while being guided by the formed screw guide groove.

In this case, the saddle 320 is slidably moved backwards along the guide rails 310, in contrast to the above operating state, and the clamping device coupled with the saddle 320 is smoothly transferred backwards, thereby clamping. Ingots coupled to the device can be transported to the rear.

In addition, in order to clamp the ingot through the finger part, the clamping cylinder 500 is driven as shown in FIG. 7A to transfer the transfer pin 520 coupled with the rod 505 to the front along the clamping hole 512.

Then, the first finger joints 530 of both sides coupled to the transfer pin 520 are opened to both sides around the transfer pin 520, and the second finger joints coupled to the first finger joint 530. The 540 rotates about the pins at both ends of the palm member 510 to position the clamping finger 550 coupled to the second finger joint 540 to be retracted inward. Therefore, the ingot located between the two second finger joints 540 may be clamped through the clamping finger 550.

On the other hand, in order to release the clamping of the ingot clamped to the clamping finger 550, the conveying pin 520 coupled with the rod 505 of the clamping cylinder 500 is transported backward along the clamping hole 512 as shown in FIG. Let's do it.

Then, in contrast to the above operation, the first finger joints 530 of both sides coupled to the transfer pins 520 are retracted inward with respect to the transfer pins 520, and the first finger joints 530. The second finger joint 540 coupled to the rotation may rotate around the pins at both ends of the palm member 510 so that the clamping finger 550 coupled to the second finger joint 540 may be opened to the outside. Therefore, the ingot clamped by the clamping finger 550 can be de-clamped.

And, the finger portion can be rotated in a predetermined rotation radius on the plane by the pivot means. That is, pivoting of the finger part is possible about the end of the guide frame 300 coupled to the arm 210 by the pivot means.

6A and 6B, when the guide frame 300 is rotated in the forward or reverse direction when viewed in a plan view, the locking ball 354 is fitted into the ball groove 352 to partially rotate the guide frame 300. Although it is limited, the locking ball 354 is fitted in the ball groove 352 in an elastic state, so that the locking ball 354 is moved away from the ball groove 352 is clouded over the flange 351. At this time, the end of the jig 350 is fitted inside the bearing housing 340, the guide frame 300 is naturally rotated by the rolling of the bearing.

When the guide frame 300 is rotated by 15 °, the locking ball 354 is mounted in a tensioned state by the compression spring, so that the locking ball 354 is inserted into another ball groove 352 adjacent thereto to block the turning of the guide frame 300. do. As such, since the ball grooves 352 are formed on the lower surface of the flange 351 at 15 ° intervals, the guide frame 300 can be pivoted at 15 ° intervals around the center of the jig 350, thereby allowing the finger portion to rotate. It can also be turned. Here, the angle indicator plate (A) is provided on the upper and lower surfaces of the flange 351, it is possible to accurately measure and estimate the angle of rotation of the guide frame 300.

On the other hand, the present invention has been described in detail only with respect to the specific examples described above it will be apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, it is natural that such variations and modifications belong to the appended claims. .
