Description
1 0~
This invention relates to a device for coping tubular metal workpieces, the said device being equipped with a die-housing which is adapted to receive the end of the workpiece and into which the cutting aperture is machined. Adjoining the said cutting aperture is a slide for a ram which fits closely therein and moves at right angles to the longitudinal axis of the workpiece. The periphery of the ram is equipped with cutters on the side facing the die-housing cutting aperture and in the vicinity thereof. In this known device, different rams and different die-housings are required for pipes of different diameters. For this reason, devices of this kind are usually stantionary, the pipes being processed in the device and then taken to ~e work site.
In assembly work, for example installing a central-heating system, requiring pipes of various sizes, prepared lengths of pipe are usually filed and ground as required in situ. This involves a considerable amount of time and labour.
According to one aspect of the present invention a device for coping tubu~r metal workpieces comprises a die-housing in which the cutting aperture is machined and an adjoining slide for a ram adapted to move in the said slide at right angles to the longitudinal axis of the workpiece and fitting closely in the said slide, the said ram also having cutters at its periphery, in the vicinity of the cutting aperture inthe die, on the side fa~ing the said aperture, characterized in that the slide is in the form of a bore located in ~he die-housing and surrounding the ram, a plurality of cutting apertures 1 0~ 19~0 for workpieces of different diameters, being provided in the said die-housing and corresponding cutters being provided on the ram and the said bore having stepped diametersadapted to each other.
The device of the present invention is preferably adapted so as to be suitable for use at a work site and to be capable of coping pipes of diameters of the type generally used at the work site.
The device according to one aspect of the invention provides a tool which is easily operated by hand, since reliable guidance of the ram is assured, and which comprises a plurality of cutting apertures, thus making it possible to process pipes of the diameters normally used with a single tool.
In addition, adjustable stops are preferably provided for controlling the extent to which a m~tal workpiece may be inserted into the die so as to control ~- the degree of copi~g formed on the workpiece.
In addition, the device of the present invention is preferably portable so as to be easily m~vable from one job site to another.
The invention will be more clearly understood after reference to the following detailed specification read in conjunction with the drawings wherein;
Fig. 1 is a p æ ti~l section through the device;
Fig. 2 is a view of a coped pipe;
Fig. 3 shows, to a different scale, the device fitted to a mobile stand.
The device consists essentially of a die-housing 1, only a part of which is shown in the drawing. The said

Fig. 1 is a p æ ti~l section through the device;

Fig. 3 shows, to a different scale, the device fitted to a mobile stand.
The device consists essentially of a die-housing 1, only a part of which is shown in the drawing. The said
- 2 -lO~`~9~o die-housing may be substantially longer for a wider range of application. It comprises a longitudinal bore 2 stepped into different diameters. I~ the example illustrated three diameters A, B and C are shown. ~bviously more such steps may be provided if required.
Arranged in the lateral wall of the die-housing, at each diameter, is a cutting aperture 3, 4 or 5 which is slightly conical in order to facilitate insertion of he workpiece to ~e processed. Guided in bore 2 is a ram 6 equipped with a cutter 7, 8 or 9 in the vicinity of each of the said cutting apertures, the said cutting edges running in the direction of the longitudinal axis of housing 1, thus making it possible to cut and cope the workpiece inserted in the relevant aperture. Ram 6 may be actuated by an eccentric 10, of which Fig. 1 shows only the actual eccentric part and a lever 11. For the sake of clarity, a toggle lever, used to simplify the drive, has been omitted from ~e drawing.
Located in the vicinity of each cutter 7, 8, 9 is a stop 12, 13 14 in the form of an ad~usting screw which may be used to control the depth of insertion of the workpiece.
The type of coping is shown in Fig. 2 illustrating a tubular workpiece 15. It will be seen that a single stroke of ram 6 produces a single arcuate cut. If two such cuts are required , the workpiece must be rotated through 180 or less.
Fig. 3 shows a stand which is generally identified by the numexal 16. The stand 16 is equipped with cc- -operating struts, and carries at its upper end two retainers, ` 10~4940 one of which, 17, is shown in the drawing. Secured to retainer 17, by means of bolts 18, 19, is the actual die-housing 1. Cutting apertures 3,4, 5 are also visible in the drawing.
