Description

Portable divider stand

The innovation relates to a portable separating stand for separating and cutting closed profiles, in particular of pipes by means of metal-cutting electric motor driven or pressure medium driven Hand tools, preferably angle grinders.

Devices for cutting and cutting pipes are often required directly at the assembly site. Easily transportable devices that produce smooth and precisely angular cuts are advantageous here guarantee.

There are pipe cutting machines are known in which the pipe to be cut is brought into circulation and by means of a is separated on a sliding carriage arranged tool. There are also pipe cutting machines known, in which the cutting tool runs around the fixed pipe. Both versions have the disadvantage that they can only be used predominantly for stationary use.

Furthermore portable separators are in the execution known as motor-driven hand tools, such as jigsaws, cut-off saws, etc., where the Separating tool acts on the clamped pipe and

is guided more or less precisely by hand or by means of auxiliary devices. This execution has the disadvantage that the cutting tool is passed through the pipe in one go and thus the largest possible The outer diameter of the pipe depends on the length or diameter of the cutting tool.

The present innovation is based on the task of creating a portable dividing stand with which Preferably pipes with different, independent of the tool, outside diameter smooth and can be separated at an exact angle

This object is achieved according to the invention in that on the base plate of the separating stand a front and a rear support with at least one, preferably with two pairs of supporting rollers arranged in this way is that workpieces with different diameters can lie in these pairs of idlers and that a “preferably spring-loaded hold-down device with at least one counter roller, preferably height-adjustable on the column of the separating stand or on the base plate, preferably between the supports and above the longitudinal axis of the workpieces' is arranged.

Embodiments of the innovation are shown in the drawings and are described below explained:

Figure 1 shows the longitudinal view of the separating

Stand designed as a combination with an angle grinder.

Figure 2 shows a section through the partition stand at the level of the front support.

FIG. 3 shows a plan view of the separating stand with an additional base plate.

The embodiment according to Figure 1 is as follows described:

The front (2) and rear (3) supports attached to the base plate (1) are different arranged support rollers (4, 5). There is a column (6) in the front area of the base plate for holding and guiding the cutting tool (7). At this column can preferably have a spring-loaded hold-down device (8) above the front support (2) Counter roller (9) are attached, which comes to rest on the workpiece (10).

711 § 41816.8.78

The embodiment according to Figure 2 is explained as follows:

The differently arranged support rollers (4 »5) mean that they can be used for different workpieces Outside diameter (10, 11) allows. The height-adjustable hold-down device (8) preferably carries At least one counter roller (9) above the longitudinal axis A-A of the workpiece. The advance of the in This example sketched parting tool (7) can preferably be vertical or on a circular path take place. Depending on the arrangement of the cutting tool, a horizontal feed movement is also possible. It is also conceivable, instead of a craftsman's eye To attach motor gear unit, wherein the feed movement can be done manually or by machine.

The embodiment according to Figure 3 is as follows described:

Pur di'e support of long workpieces can be an additional Base plate (12) with further support rollers (13) attached to be adjustable via guide elements (14) will. By changing the position of the cutting tool can also be used for workpieces with small Diameter miter cuts (B-B) carried out exactly will.

The advantages achieved with the innovation are in particular that workpieces with different Outside diameter can be separated so that the parting line is in the same position all around remains, i.e. that the start and end of the joint meet without any significant offset. This is for Production of absolutely tight pipe connections required.

Another advantage of this innovation is the transportable design, which is particularly suitable for fast Cutting, cutting to length and chamfering on assembly points.

The possibility of combining and exchanging base plates, supports and rollers and the adjustability of these elements, including the column supporting the tool The present innovation is a universal device for efficient cutting and cutting to length.
