Abstract

The equipment has a clamping device (1) and is suitable for various pipe end machining processes. The clamping device and the machining equipment (2) are arranged on a common work plate (3) and are transportable. The machining equipment is exchangeable. The clamp device can be used for pipe bends of various dimensions, with regard to external diameter, curvature radius and length of bend.

Description

The invention relates to a device for processing pipe ends of Elbows.

It is common practice to connect pieces of pipe to these weld. For this it is necessary to prepend the pipe ends accordingly ride, for example, the tube ends using a milling machine chamfered. In the case of straight pipes, this is without difficulty according to the status of technology possible.

So far it has been common for pipe bends to close their ends at fixed workplaces edit, d. H. possibly further away from the actual use place of the bent pipe parts. It would be an advantage if the clamping Direction on site and can be used for existing processing machines would.

DE OS 35 09 670 describes such a device for chamfering Pipe bend described. Here, the pipe sections are clamped thorn shaft selectively clamped from the inside.

The disadvantage of this internal clamping is in particular that the Milling machine moves while milling, d. H. it can swing out and thus only deliver inaccurate and faulty pipe ends, which is a larger one Committee means.

The object of the present invention is therefore to provide a device for Machining pipe ends from pipe bends to propose the site is available and operable and a clean result, d. H. low Reject rates enabled.  

According to the invention, the object is achieved in that the device has a Has clamping device and for various pipe end processing devices can be used suitably, the clamping device and the Pipe end processing device together on a worktop are arranged and the device is portable.

The device is designed so that it is available for milling machines Location is easy and safe to use.

Depending on the application, the pipe end processing device can be advantageous be interchangeable. That is, the device according to the invention allows the same types of machine tools same size.

According to a preferred embodiment, the clamping device is for Elbows of different dimensions, with regard to outside diameter, Radius of curvature and arc length can be used.

The clamping device is different depending on the pipe bend dimensions settable.

It is particularly advantageous to clamp the pipe bends from the outside.

The external tension of the pipe parts is done for example Clamping jaws that vary depending on the outside diameter of the pipe parts can be shaped.  

An embodiment is shown in the drawing. They show:

See Fig. 1 is an overall view of the device from the front,

FIG. 2 shows a sectional view BB from FIG. 1

Fig. 3 is a plan view with clamped pipe bend large dimension and

Fig. 4 is a plan view with clamped pipe elbow small dimension.

In Fig. 1 is an overall view of the apparatus is shown from the front. The main elements are the actual clamping device 1 , the pipe end processing device 2 and the common worktop 3 .

In this example, the pipe end processing device 2 is a milling machine 4 with a milling tool 5 for chamfering pipe ends. The jig 1 consists of a table 7 which rests on the supports 6 connected to the work plate 3 . On the table 7 , a clamping device 8 is attached, which is arranged perpendicular to the plane of the drawing along the rod 9 and can be locked via the lever 10 . The clamping tool has clamping jaws 11 which can be operated in a suitable manner via the spindle 12 . Another clamping tool 13 with clamping jaws 15 movable via a spindle 14 is arranged on the table 7 . This clamping tool is both longitudinally displaceable and pivotable by means of the spindle 16 (see FIGS. 3 and 4).

FIG. 2 shows the sectional view BB from FIG. 1. The clamping tool 13 can be moved along the rod 17 and can be locked via the lever 18 . The clamping tool 13 is, as already mentioned, guided by the groove 20 , pivotable.

In Fig. 3 is a plan view of the jig 1 with a clamped pipe bend (shown in phantom) 21 with a large diameter represents Darge. The pipe bend 21 is clamped into the clamping tool 8 on the side facing the milling machine. The other end of the pipe bend 21 is clamped in the clamping tool 13 . This is a pipe bend 21 which extends over 90 °. For clamping pipe pieces that are larger or smaller than 90 °, the clamping tool 13 is pivotally provided via the levers 22 and 23 . The lever 22 is guided in the guide groove 20 and held rotatably about the pivot point 24 .

Fig. 4 shows the situation in plan view with a clamped Rohrbo gene 19 with a small diameter.
