Description

The invention relates to a profile rolling machine with several rolling stations arranged one behind the other, each consisting of from two spectacle bearings connected to the machine table, between which the driven shafts for the ones pushed onto it Upper and lower rollers are held.

Depending on the nature of the tape to be profiled are arranged in these known profile rolling machines on a machine table several Walzatationen that Rolled stock passes through one after the other. The establishment of the individual rolling stations with the different from station to station Rolling requires a significant amount of work and time.

These set-up times affect these profile rolling machines

significantly the degree of use. {

In a known machine of this type, the shafts arranged one above the other are on one side in fixed bearings the sub or. the top rollers held. The drive of the individual shafts can, for example, via connecting chain drives respectively. The other shaft ends are each held in glasses bearings that can be mounted on the machine table prop up. To set up such a profile rolling machine, all glasses bearings must be removed. Both the Shafts held with a screw connection as well as the fastening screws of the glasses bearing on the machine table solve. The spacers and the pushed-on profile rollers must then be removed from the shafts. Other roles are to be assembled and fixed in reverse order and, if necessary, still to be set up.

The object of the invention is to reduce the set-up times on such profile rolling machines with several rolling stations.

To achieve this object of the invention, such a profile rolling machine is therefore characterized by one on the machine table adjustable common base plate on which the rolling

Stations are set up.

"A preferred embodiment of the invention is included on the base plate for each rolling station oppositely mounted spectacle bearings, between which the shafts that can optionally be adjusted in height are held, with on one or both shafts a gearwheel or a sprocket is attached to a shaft stub. The glasses bearings can be equipped with a Screw connection should be held on the side of the base plate.

With the suggestion according to the invention it is nifelich, already set up all rolling stations on the common base plate and set up this preassembled unit in a short time to set up the machine table of the profile rolling machine.

There is the possibility of having such a base plate with its rolling stations arranged at a distance from one another to set up the shafts of conventional machines, so that the invention also with machines that are already in use can be used as a retrofit.

The time-consuming assembly work is reduced by the proposal according to the invention to the area of the machine in the area of a relocated outside pre-assembly. This significantly reduces the set-up times previously required on the machine.

Based on an illustrated embodiment, the Invention explained in more detail below.

It shows:

Figure 1 is an end view of a base plate with several rolling stations

and

FIG. 2 shows a plan view of the arrangement according to FIG. 1.

The actual profile rolling machine is not shown in the figures with the machine table. The base plate 1 can be set up on the machine table with its several preassembled

Rolling stations I, II For fastening this base plate 1

the holes 11 are provided on the machine table through the screws are pulled through. Usually two screw connections are sufficient.

The pre-assembled rolling stations each consist of the two oppositely arranged spectacle bearings 2 and 3, in where the shafts 4 and 5 are mounted. The profile rollers, not shown, are pushed off in a form-fitting manner on these shafts.

Each spectacle bearing can be fitted laterally with a screw connection 6 on the base plate 1. In the glasses bearing 2, for example, the floating bearings 21 b; sw. 22 and in the spectacle bearing 3 the fixed bearings 31 and 32 for the shafts 4 and 5

\ provided. Springs 41 are attached to the shafts in a known manner

and 51 for a positive connection with the slide-on Roles used.

On the shaft journal 42 and 52 can chain wheels or

Such a preassembled unit, in which on the base plate 1

the rolling stations I, II fully set up and preassembled

can in a short time with the screw connections on the prepared machine table of a profile rolling machine to be set up. The individual shafts are driven either by chain drives or spur gear drives.

The interchangeable stations offer not only the possibility of pre-assembly of tools, but also of the individual, tool steel-saving Cutting to the respective profile shape, in particular the profile height, i.e. one can in continuous sequence E.g. a unit of 6 stations with a vertical shaft distance of 80 mm and a further 6TSVnIT ^ a distance of 160 mm. Since only the lower or upper shaft is coupled to the prime mover and the respective counter shafts are driven within the stations, the rotational speeds of the profile rollers are matched to the smallest possible relative movements.
