Hot plate press in window frame design

The invention relates to a hot plate press in window frame construction according to the preamble of the protection claim.

In such a hot plate press, the press ram and the press table consist only of web plates and cross ribs connecting them (DE-OS 31 49 24.3, DE-OS 37 02 995). Several web plates with cross ribs are welded together to form a box beam, which in turn, by lining up and attaching heating plates, represent the length of the press ram and press table and thus the hot plate press. The projections or cantilevers protruding from the web plates on the left and right act as abutments for the tension frame press stands for raising and lowering the press ram, with the press cylinder piston arrangements arranged between the upper cross heads and the projections of the press ram. A hot plate press designed in this way ensures perfect plane-parallel pressure transfer of the press plates across the width of the material to be pressed.

The invention is based on the object of designing the generic hot plate press in such a way that the material costs, manufacturing costs and assembly costs are reduced considerably.

This object is achieved according to the invention by the horizontal arrangement of crossbeams in the upper and lower crossheads of the tension frame press stands in such a way that to the left and right of them there are pins into which tension straps with eyelets are hooked in such a way that they connect the upper with the lower crossheads.

One advantage of the invention is that the use of the tension straps results in considerable savings in production, since the tension straps with the eyelets are simply hooked onto the pins of the crossheads. The costly welding work for the previous tension plates is no longer necessary.

Figures 1 to 5 show a preferred embodiment of the hot plate press according to the invention.

Show it :

Fig. 1 the hot plate press in side view,

Fig. 2 the hot plate press according to Fig. 1 in front view in section and

Fig. 3 the heating plate press according to ?ig. 2, but with

built-in pull tabs.

According to Fig. 1 to 3, the main components of the hot plate press consist of the fixed press table 3, the movable press ram and the tension frame press stands 1 guided on the two long sides of the press table 3 and anchored to the press ram 2. The press ram 2 and the press table 3 consist only of the web plates 7 and 8 and the cross ribs 9 and 10 connecting them. Several web plates 7 and 8 with cross ribs 9 and 10 are welded together to form a box beam, which, by lining up and attaching the heating plates 16 and 17, form the length of the press ram 2 and press table 3 and thus the hot plate press. The approaches 21 and 22 or projections protruding from the web plates 7 and 8 on the left and right act as abutments for the draw frame press stands 1 for raising and lowering the press ram 2, with short-stroke press cylinder piston arrangements 6 being arranged between the upper crossheads 11 and the approaches 21 of the press ram 2.

A tension frame press stand 1 consists of two tension straps 13», the upper crosshead 11 and the lower crosshead 12. A crossbeam 25 with pins 26 protruding to the left and right is attached to the upper and lower crossheads 11 and 12. To connect the crossheads 11 and 12, the tension straps 13 are hooked onto the pins 26 with their eyelets 27.
