Description

Die Erfindung läßt sich auf verschiedene Weise weiter ausbilden, wobei für die zum Teil an sich aus den Entgegenhaltungen bekannten Merkmale für sich kein Schutz begehrt wird, sondern nur im Zusammenhang mit den übrigen Merkmalen des Schutzbegehrens. So können zweckmäßig die Traversen aus I-Profilen bestehen, gegen die als Stirnplatten Rahmenstäbe gesetzt sind, während als Seitenplatten Rahmenstäbe seitlich in die I-Profile der Traverse eingesetzt sind. Dabei können die Traversen, der Rahmen und die Deckbleche miteinander durch Schraubenbolzen verbunden sein. Zweckmäßig bestehen die Preßeinrichtungen aus Spannbügelverschlüssen und zugeordneten, an den Stirnplatten angeordneten Lagerwangen und Aufnahmen. Auch können die Spannbügelverschlüsse in sich nachspannbar sein. The invention can be developed in various ways, where for the features known in and of themselves from the references for no protection is sought, but only in connection with the other characteristics of the protection request. So the trusses can be made of I-profiles, against which frame bars are set as face plates, while frame bars are used as side plates laterally in the I-profiles of the traverse are used. Here you can the trusses, the frame and the cover plates are connected to one another by screw bolts be. The pressing devices expediently consist of clamping yoke locks and associated, bearing cheeks and receptacles arranged on the end plates. The clamps can also be used to be retensioned in itself.

Vulcanizing press for repairing or making endless of conveyor belts, with a lower and an upper press plate, each from one Frame, a lower and an upper cover sheet and between the latter within of the frame are made parallel to each other arranged cross members, wherein the press plates can be pressed against one another by pressing devices, characterized in that that the pressing devices (4) on the end faces extending transversely to the cross members (3) the press plates (1, 2) are arranged.

2. Vulcanizing press according to claim 1, characterized in that the traverses (3) consist of I-profiles against which frame bars act as end plates (8) are set, while as side plates (9) frame bars laterally in the I-profiles the traverses (3) are used.

3. Vulcanizing press according to claims 1 or 2, characterized in that that the crossbars (3), the frame (7) and the cover plates (6) together by screw bolts (10) are connected.

4. Vulcanizing press according to one of claims 1 to 3, characterized in that that the pressing devices (4) from clamping bracket closures and assigned to the End plates (8) arranged bearing cheeks (11) and receptacles (12) exist.

5. Vulcanizing press according to one of claims 1 to 4, characterized in that that the clamping bracket locks can be tightened in themselves.

The invention relates to a vulcanizing press for repair or making conveyor belts endless with a lower and an upper press plate, each consisting of a frame, a lower and an upper cover sheet and between the latter there are cross members running parallel to one another within the frame, wherein the press plates can be pressed against one another by pressing devices.

In a known vulcanizing press, the one described above Type (see German Auslegeschrift 1189 265) additional components are provided, on which the press plates can be supported. For example, above and at the bottom two traverses running transversely to the longitudinal axis of the conveyor belt are arranged which the press plates are statically as a first approximation as a beam on two supports prop up. Corresponding embodiments are also the more up and down known as two trusses. The traverses are connected to each other by means of tension bolts, that can be tensioned. They also carry hydraulic ones, mostly distributed along their longitudinal axis and / or mechanical pressing devices for generating the pressing pressure, e.g. in the form of cylinder piston arrangements or tensioning screws.

In the known vulcanizing press, the traverses are in the press plates designed as I-profiles. In particular, the assembly of the known Vulcanizing press time consuming and labor intensive. Furthermore, the space requirement is considerable in terms of height. For Vulcanizing presses of a similar type are known box-shaped press plates (cf. German utility model 6931 654), in which against one consisting of a U-profile Frame cover plates are fastened by means of screw bolts. The cover sheets mutually supporting crossbars are not provided. The required flexural rigidity the press plates is therefore not guaranteed. That also applies to another well-known one Press plate (see German utility model 1 923 658), in which the heating devices are laid serpentine within a frame between the cover plates. In addition, reinforcement profiles connecting the cover sheets are between the individual windings arranged. However, these can therefore not be used on both sides of the end plates as traverses be connected.

For completely different purposes, namely to isolate the connection point of two connected to each other and provided with a rubber coating electrical Ladders, a vulcanizing press is known (see French patent 1 163 860), in which two jointed press plates made of solid material are provided are. There are recesses in the press plates to accommodate the electrical conductors and the associated casing. To lock the press plates is a retensionable clamping bracket lock is provided. A transfer of these measures on vulcanizing presses of the type described at the beginning cannot be realized since the modern conveyor belts require an order of magnitude of the pressure plates, which excludes manufacture from solid material.

The invention is based on the object of a vulcanizing press To design the type described in the simplest way so that the cumbersome Assembly of the press plates between the receiving crossbars and the associated one There is no need for connecting means between these crossbars. According to the invention, this The object is achieved in that the pressing device on the transverse to the traverses End faces of the press plates are arranged.

The advantages achieved by the invention are mainly therein to see that the pressing devices are arranged directly on the pressing plates and thus the complex assembly of additional enclosing the press plates between them Traverses and connecting elements and their dismantling are no longer necessary. In particular, will the number of individual parts required to assemble the vulcanizing press is considerable reduced. This is especially true when repairing or making conveyor belts endless in underground operations. It is also of particular importance that the inventive Vulcanizing press a significant reduction in space requirements in relation to the Height when carrying out the vulcanization allows.
