Description

Device for connecting profile bars to one

Frames, especially for the manufacture of windows The invention relates to a device for connecting four profile bars to form a frame, especially for the installation of windows made of plastic, consisting of a Stand with a turntable, the four pivotable, horizontally arranged guide rails on each of which one from a cylinder-piston unit and one horizontal displaceable contact angle existing PreP tool displaceable and lockable is arranged.

Such a device is made for the manufacture of windows Aluminum profiles became known. This consists of a stand with a slewing ring, on which a bar made of a square tube is mounted, on which two sleeves can be moved are, which carry a bearing for guide rails on both sides, on which ever one from a 7th cylinder Eolben unit and a horizontally movable contact angle existing Preßwerkseug is arranged displaceable and lockable.

To make a window, four previously cut Aluminum profile rods inserted into the bracket formed by the pressure angles, after previously the sleeves at a certain distance from the axis of rotation of the stand were set and determined and during the insertion the pressure angle accordingly the dimensions of the profile bars can be set. Then becomes a printing medium placed on the cylinder-piston units, whereby the four profile rods are firmly held together will.

Then holes are made in the profile bars to create corner angles to screw on. This bracket would be in the horizontally movable contact angles however, it can also be suitable for welding work in the corners of the frame.

This device is suitable for the production of frames from aluminum profile bars, But not for the production of frames from plastic profiles. Because aluminum is a harder material that does not deform under the pressure of the contact angle. Therefore, the technology for the manufacture of frames from plastic profile rods other devices created.

A known device for connecting profile rods made of plastic Combine two profile pieces to form a spelled. their operation requires a lot of expertise and a lot of attention, <i # with the profile bars correctly and be inserted in such a way that an exactly brefertir ter frame is created. This is right now in the case of frames for the production of windows, it is very important to ensure that they are tight conclude. It is also a device for connecting profile rods made of plastic known, with the four profile bars at the same time get connected. Here is made up of guide rails that run perpendicular to one another a kind of large frame is formed, which is set up almost vertically in a slightly inclined position is and on the slidably clamping tools and pressing tools are arranged. These Device is very complex and accordingly costs a lot. She is also suitable only for welding plastic profile rods, as drilling holes for example, for other types of connection than welding because of the ease of use Inclined position would be cumbersome and only feasible with great effort and more precisely also make aeirde aeirde necessary to work with large frames also get to the upper profile bar.

The present invention has for its object to be a simple constructed device that can be used universally for various types of connection to create, with which four profile rods can be assembled into a frame with high precision are.

The invention is based on a device of the type mentioned at the beginning to solve this problem and consists in that each pressing tool on one pivotable and lockable support plate for the profile bars is attached, that on each support plate a stand for a further cylinder-piston unit is arranged with a vertically displaceable pressure plate and that each guide rail is attached to a handlebar which is mounted on one side in the axis of the stand is and at the other Anlenkpuiilct the guide rail is articulated with a pin is.

It is the advantage of this device that you can use it universal Assemble profile rods to a frame with different connection types and can connect.

It is the advantage of this device that you can use it universally small and large frames and frames with extremely small dimensions in one direction and can produce extremely large dimensions in the other direction. It will the high accuracy of the frames produced is guaranteed by the support plates, because then from the beginning four profile bars lie in one plane and therefore already can be put together exactly before clamping with pressing tools. In this The profile bars are in position by applying pressure from above using the pressure plates held by the vertically acting cylinder-piston ¢ units. Only then will the four profile bars pressed together at their beads by the sliding contact angle. This enables the device to work with high precision and manufacture more precisely Frames that have exactly the desired dimensions, that are manufactured at exactly the right angle are and their profile bars are not the slightest tilt or twist against each other exhibit.

Different types of connection can be used for the profile bars run on this device: It can be all-plastic profile rods, the consist of a thermoplastic profile, the chambers of which are covered with a thermoset are filled in and the front edges produced by a miter cut an adhesive, in particular two-component adhesive, is applied to one Connect frames with exact dimensions and exact right angles. For this So far there is no suitable device at all for the type of plastic profile rods.

However, such solid plastic profiles can also be combined with one another Connect with dowels and screws, it is useful if in the vertical sliding pressure plate and / or in the jaws of the pressure angle as templates Serving bores are provided through which the drilling tool is guided. This The drilling tool can then be set up at a specific workplace. By the rotation of the turntable will be sequentially all four corners of the to be produced Frame brought to this workplace.

However, the device can also be used to connect profile bars to one another to weld. A welding mirror inserted between the miter cuts becomes then after the simultaneous heating of all eight pairs to be welded together Areas withdrawn by an additional device, after which the four slidable Squeeze the four profile bars together to form a frame. Ilierbei is it is useful if each contact angle consists of two jaws that are spaced apart are arranged from the apex of the angle.

But also let connections with connecting angles and screws produce on this device, the jaws of the contact angle and the vertically displaceable pressure plate can be designed as a drilling template.

In addition to this universality of the application of different types of connection the device according to the invention has the advantage for a wide variety of frame sizes to be universally applicable. This is ensured by the fact that each guide rail is attached to a handlebar which is mounted on one side in the axis of the stand is and at the other articulation point, the guide rail with a Pin is hinged. In this way, the guide rails can be paired arrange very close to each other.

For the exact setting, it is useful if the slewing ring of the Stand consists of a plate that has four elongated holes parallel to its circumference has, in which the bearing journals of the guide rails engage.

It is advantageous if on the plate of the rotating rim of the stand four scales for adjusting the guide rails are arranged.

Because the guide rails are relatively long for the production of large frames are, it is useful that under each guide rail one over a turntable is arranged on the stand stored ter support arm. This gives the guide rails a support that ensures its exact position in a horizontal plane.

It is advantageous if the stand is hollow inside and in his Inside there is a distributor for the pressure medium to the individual cylinder-piston units having.

This distributor device can also be rotatable, so that the turntable can be rotated as often as required in one direction. But there is also the possibility to use as a distribution device a fixed, which is via hoses; with the cylinder-piston units or with leading to the cylinder-piston units Pipes is connected.

These hoses can then rotate the swivel ring to a certain extent take up. Here it is necessary to reduce the twistability of the l) RehILranzes to one to limit a certain angle value of e.g. 400 ° or 800 ° so that the slewing ring fully Twists one full turn or two full turns is rotatable.

It is advantageous if on each platen parallel to the Legs of the contact angle extending Ijarkierungen or scales are arranged. This facilitates the exact placement of the profile bars on the support plate.

It is also advantageous if there is a scale on each guide rail and a pointer assigned to this scale is arranged on each pressing tool.

It is also advantageous if on one in the guide rail displaceable and lockable support device for the support plate a Scale and a pointer on the hoof-pad. Get on this track the settings for making different frames without prior Try exactly set. here ç through is achieved that the labor productivity of the device is high without the n% -activity of the frames produced underneath suffers.

It may be useful that the cylinder-piston unit for the vertically displaceable pressure plate attached to its on the platen Stand can be pivoted in two positions. This is advantageous when the cylinder-piston unit would be in the way of a drilling tool, which holes from should bring up into the frame.

It can be advantageous if the guide rails are telescopic are formed, so from two or several slidable one inside the other Hollow pipes exist.

In this case, you will expediently on one part of the telescopic Guide rail arrange a scale to accurately adjust the length of the guide rail to reach, at the Lde then expediently the support plate immovable is stored.

It is advantageous if the uprights of the cylinder-piston unit The vertically moveable pressure plates of two opposing pairs of guide rails in pairs on different sides of their support plate are arranged. This has the advantage that a finished frame through a horizontal movement in the plane in which it is located during its manufacture found can be removed from the device.
