concerning
Roll forming machine

The present invention relates to a roller machine or bending machines and special roller forming heads for such machines. .

Known roller porm machines have heads that are of the type Include designed rolls to make the shapes you want to train or manufacture in plates and the like The main disadvantage of these machines is, however, that eo to change the shape made by the machine guided boards, it is necessary to remove the rollers and replace them with other rollers, which many The Maaohina can and requires hours to complete has been out of service for a considerable period of time.

It is an object of the present invention to achieve this Ilaohteilo to avoid or to diminish.

This object is achieved according to the invention in that a RoIL ^ n-Foncmaahine comprises a roller forming head, the

Has shafts or spindles on which two series of rollers are attached, the roller head being adjustable in such a way that the parts or spindles can be arranged so that one or the other series of rollers can be brought into an operating position is.

In the following the invention is illustrated schematically Drawings explained in more detail at an Ausflassungbeiapiel.

It shows

Fig. 1 is a partial perspective view a roll forming machine with a role according to the invention n-Forcikopf;

Pig. 2 is a partial side view in which. the drive of the rollers can be seen;

Pig. 3 is a view corresponding to Pig. 2, with the drive disengaged to a To allow adjustment of the head; and

Pig. 4 shows a section essentially along the line IY - IV in Pig. 3.

The roller Pormmaachine shown is intended to make the shaping of two parallel edges of a board. This machine comprises a base frame 10 which underpins two intermediate frames or auxiliary frames 11 which are arranged at a lateral distance from one another and each of which carries a roller forming head 12, as well as drive means 13 for driving the rollers of the heads 12 _# .

Each head 12 comprises a frame H which supports a series of pairs of parallel, vertically spaced shafts 15 which

pass through this frame 14, in the area of each A forming roller 16 can be provided at the end of each shaft or spindle 15 be attached, the form roller 16 in the region of one end of each shaft or spindle 15 has a different shape than the form roller 16 arranged in the area of the other end of the shaft.

The shafts or spindles 15 are driven by gears 17 driven, which are arranged between the ends of the shafts or spindles 15 in the central region of the frame 14. Each form head frame 14 is attached to it with one Ring 18 provided in its central area, this ring has a diameter that is straight into one of the attached corresponding intermediate frame 11 of the machine Ring 19 fits. An annular channel 20 on the outer edge of the inner ring 18 is in engagement with a threaded pin 21, which extends through the outer ring 19. In this way, the forming head 12 can be on the Rotate between 11, the ring -18 sioh in the Ring 19 rotates.

In order to fasten the forming head 12 in the desired operating position, the forming head 12 is provided at one end on each side with a block 22 provided with recesses, which is set up to be in alignment with an opening 3 on the associated intermediate frame 11 to be brought, wherein a locking pin 24 is attached to the intermediate frame 11 with a chain and is intended to be inserted through the recessed block 22 and S. di «recess or opening 23 to be inserted to secure the forn head 12 in its position»

The drive of the rollers 16 of each head 12 is by means of ao Llotors 26 over sprockets 27 and 28 and a chain causes this chain drive approximately in the middle of the

Gaps 11 is. The sprocket 28 is on one Shaft 30 attached, which carries another sprocket 31 on the inside of the intermediate frame na 11, this Sprocket 31 via a chain 32 another sprocket 33 drives, which is attached to a shaft 34 parallel to the shaft 30 su. A gear 35 is aaif this Wells 34 et.va fastened in the middle between the ends of the same and is in engagement with a middle, lower gear 17. The lower gears 17 of each frachead 12 are driven by idler gears bsw. Idler gears 36 interconnected.

The shaft 34 »the chain wheel 33 and the gear wheel 35 are vertically adjustable as an assembly and for this purpose are supported by a support arm or bearing block: 37 worn on each side of the Zwischenrahaien3 11, these Support arms 37 are vertically displaceable in guide slots 38. A nooke 39 engages each of the support arms 37 and can be rotated by means of a handle 40.

In one position of the cam 39 (Pig * 2) a Drive transmitted to the gears 17 and 36 while in another position of the cam 39 (FIG. 3) the assembly 33, 34 and 35 is lowered and the drive is interrupted

If you want to change the shape that is given to a table guided by the machine, the heads 12 can be rotated. to turn the others forward on the plate. The assembly 33, 34 and 3i> is lowered, the chain 32 being held taut by a spring-loaded tension roller 4i, the head 12 is rotated, the pins 24 are brought into their position in which they hold the forming head 12, and the assembly 3 3, ⁷ ^ and is finally raised in order to come into engagement with the drive dea K.

In such a role JOrflimasahine is one of the The shape of the head can preferably be adjusted laterally achieved by the fact that the intermediate frame is laterally displaced is slidable, the sprockets 31 and 33 slide on their shafts * with which they are wedged when the Intermediate frame is moved »

Each of the roller forming heads 12 can be easily removed and replaced by unscrewing the threaded pin 21 in the outer ring 19 and the forming head 12 is lifted from the intermediate frame 11.

This way, during a set of the forming rolls another one is set up or set up in use and the shape given to the iafel with a minimal Loss of machine time and operator time can be changed.
