In order to improve the productivity of this continuous processing, cutting and welding are performed. There is an increasing demand for so-called running machining, in which machining is performed while the steel material is running.

[0003] Conventionally, as a running machining facility for performing this running machining, for example, as shown in FIG.

An object of the present invention is to provide a clamp device for a machining apparatus during traveling, which can adjust a clamp position with high precision.

[0008]

Means for Solving the Problems The first invention of the present invention is:
A traveling body on which the processing device is mounted is disposed so as to be able to travel forward and backward along the transport direction of the material to be transported, and the traveling body is moved forward along with the material to be transported, and the material to be transported is processed by the processing device while running. In the traveling machining equipment, in a clamp device provided for clamping a material to be conveyed, an elevating frame body having a clamped surface of the material to be conveyed at a lower portion can be raised and lowered on the traveling body via an elevating device. A clamp body having a clamped surface of a material to be conveyed formed on the upper portion of the lift frame body is provided so as to be able to advance and retreat via an advance / retreat device.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION In the clamp device of the present invention, an upper clamp and a lower clamp are supported by an integrally formed frame (housing), and the clamping force of the fluid pressure cylinder is reduced to an internal force in the same housing. The main feature is that the vertical position of the housing can be independently controlled by a driving device (elevating device) provided outside the housing.

In this manner, when the height position of the clamped steel material is adjusted, it becomes possible by the operation of the driving device provided outside the housing irrespective of the cylinder for moving the clamp plate up and down. Position adjustment control is simplified. Since no clamping force is applied to the driving device, the clamping position can be easily adjusted with a relatively small hydraulic pressure.

Therefore, by applying the present invention, it is possible to adjust the height position of the steel material in a clamped state with high accuracy, to reduce the oil consumption rate, and to prevent the equipment from being enlarged.

As the lifting device for the lifting frame and the retracting device for the clamp body used in the present invention, a hydraulic cylinder device such as a hydraulic cylinder or an air cylinder is generally used, but other mechanical or electrical lifting mechanisms are used. May be used. These devices may be directly connected to the lifting frame or the clamp body, or may be connected indirectly via, for example, a taper liner.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a clamp device according to the present invention. This embodiment is a case where the clamping device of the present invention is applied to a running welding facility for welding the steel sheets conveyed by the conveying rollers 3 between the running in a continuous steel sheet processing line.

In the traveling welding equipment, as shown in FIG. 5, the traveling body 2 is moved forward with the steel plates 6a and 6b, and the clamping device 7 of the present invention mounted on the traveling body 2 is mounted.
After the rear end of the steel plate 6a and the front end of the steel plate 6b are clamped by a and 7b, and the end surfaces of both steel plates 6a and 6b are butted, the welding unit 1 of the processing apparatus 1 is moved between the butted portions.
The welding is performed by w, and as soon as the welding is completed, the traveling body 2 is moved backward to the standby position.

In FIG. 1, reference numeral 1 denotes a processing device provided with the clamping devices 7a and 7b of the present invention and a welding device 1w, which is mounted on a traveling body 2 which is driven by a driving device Ma. The traveling body 2 is disposed so as to be able to travel forward and backward with respect to the transport direction on a track 5 laid on a gantry 4 along the transport direction by a transport roller 3. The transport roller 3 is retracted
It is composed of one that does not perform a return operation and one that performs a retraction and return operation, and is rotated by a driving device (not shown).

In the traveling welding equipment, in order to avoid interference between the lower end portions of the clamp devices 7a and 7b and the transport roller 3 in the traveling area of the traveling body 2, the transport roller 3
While automatically retracting the lower part, the clamping device 7a,
A mechanism for clamping the steel plates 6a and 6b conveyed continuously back and forth at 7b almost simultaneously, welding after running welding with the welding device 1w, and returning the conveyed rollers retracted below to the conveyance position (not shown). ).

The clamping device 7 of the present invention used here
An example of the structure of a and 7b will be described. 1 and 2, reference numeral 14 denotes a support frame of the traveling body 2, and a pair of guide members 15 is fixed to the support frame. 1
Reference numeral 6 denotes a lifting frame (housing) including an upper frame 16o, both side frames 16s, and a lower frame 16u.
s is slidably engaged with the guide member 15 up and down.

The elevating frame 16 is supported by a hydraulic cylinder 17 as an elevating device disposed on the support frame 14 so as to be able to move up and down, and the vertical position thereof can be adjusted. A pair of hydraulic cylinders 18 is provided above the upper frame 16o of the elevating frame 16 as an advancing / retracting device, and the piston rod 18p penetrates through the upper frame to move inward of the elevating frame 16. The upper clamp body 19 is supported by the hydraulic cylinder 18 so as to be able to advance and retreat with respect to the steel plates 6a and 6b.

The upper surface of the lower frame 16u of the lifting frame 16 is a clamping surface for the steel plates 6a and 6b conveyed by the conveying roller 3, and the hydraulic cylinder 18 lowers the upper clamping body 19 to thereby raise and lower the frame. Clamp surface (lower clamp) of lower frame 16u of body 16 and upper clamp body 1
The end portions of the steel plates 6a and 6b can be clamped between the nine clamping surfaces.

FIG. 3 conceptually shows another example of the lifting structure of the lifting frame 16 in the clamp device of the present invention.
In the above example, the lifting frame 16 is lifted and lowered in a suspended state via the hydraulic cylinder 17 as a lifting device, but here, a hydraulic cylinder as the lifting device in which the lifting frame 16 is disposed on the support 20 is used. At 21, it is raised and lowered while being supported from below.

FIG. 4 conceptually shows another example of the lifting structure of the lifting frame 16 in the clamp device of the present invention. In the above example, the lifting frame 16 is raised and lowered in a suspended state or in a supported state from below via the hydraulic cylinder 17 or 21 as a support lifting device, but is disposed on the support 22 here. By causing the tapered liner 24 that advances and retreats in the horizontal direction by the hydraulic cylinder 23 to advance and retreat in a state of engagement with the inclined locking surface 25t of the locking hole 25 formed in the lifting frame 16, the taper surface 24t of the taper liner 24 is used. The lifting frame 16 is raised and lowered.

In the case of the elevating device of the taper liner interposed type, the elevating and lowering of the elevating frame can be more smoothly adjusted in minute units than in the case of direct elevating and lowering using a hydraulic cylinder, for example.

In the clamp device of the present invention, as described above, (1) the upper clamp surface (clamp body) and the lower clamp surface (upper surface of the lower frame) are formed on an integral frame elevating frame (housing). (2) Adjustment of the vertical position of the lifting frame is performed by a lifting device separately provided outside the lifting frame. (3) Position of the upper clamp surface (4) The lifting / lowering device for the lifting frame only needs to bear the weight of the lifting frame, so that the capacity and weight can be reduced. (5) The clamping force is completely raised and lowered. Because of the internal force of the frame, it is easy to move the steel plate up and down at the time of clamping (it is easy to adjust the height of the leading steel plate and the succeeding steel plate). Position of the torch of the welding equipment This system is completely different from the system to be clamped, and the lifting frame with the clamp is moved up and down to adjust the height position of the material. Adjustment can be easily performed with high accuracy, and since no clamping force is applied at the time of height position adjustment, equipment costs can also be reduced.

Although the above embodiment is an example in which the present invention is applied to a running welding equipment for a thick steel plate, the present invention is applied to a metal material and a non-metal material other than a steel plate. Not only that, the present invention can be applied to other running (including processing) facilities. Further, regarding the type, structure, shape, driving device, and the like of each element for forming the present invention,
It is changed according to the processing target, shape, size, processing content, processing line speed, and the like.

[0026]

According to the present invention, the height position of the material to be conveyed is adjusted by moving the lifting frame having the clamp portion up and down in a system completely different from the system for clamping. It can be easily adjusted with high precision, and since no clamping force is applied when adjusting the height position,
Effects such as a reduction in equipment costs can be obtained.
