Curing presses Weekly series intended for docking and repair method of hot vulcanization of rubber conveyor belts up to 800 mm wide with a length of 750 mm before seam in stationary conditions or directly with the conveyors. Operating experience of vulcanizing presses for 20 years has shown that when done correctly dock (recommendations docking tapes supplied), the term of the joint service is the entire service life of the conveyor belt. Tests splice conveyor belt 800 mm wide, made VIKLS press - 800 conducted in a laboratory mill conveyor belts FTT STOMIL WOLBROM (Poland) showed that the control joint strength is 1.5 times higher than the regulatory requirements, which is caused by high pressure and temperature uniformity. Compact and light weight allow the media to transport it in any car, and available and inexpensive materials used to perform the docking. With the start of production units produced more than 110 series presses Weekly various modifications, which are successfully used in enterprises of Ukraine, Russia and Poland. Weekly series of presses composed of three main components: body - beam, the clamping device, regulating and control block (ORM). Corpus beam for the uniform transmission of force from the clamping device on the conveyor belt vulcanizing portion and heating to vulcanisation temperature. Combining the functions and the pressing beam heating plate allowed to minimize the number of components and, consequently, reduce the assembly time presses to 5 minutes, reduce the overall weight of the press, optimize the cost of materials and manufacturing and thus reduce the price of presses. The heating cooker body - beams made of high strength aluminum alloy, and as the heating elements are applied patented heaters surfactant - distributed heat generation that allowed for: - high level of electrical and fire safety; - a high thermal efficiency, short time heating and cooling; - increased reliability and service life of heaters; - high quality docking and repair conveyor belts; - lightweight hot plate. Locking device intended to create pressure on the vulcanizable portion of the conveyor belt of up 8kgs / cm2 (0.8 MPa) by means of a screw pair (cargo screws). The use of a thrust bearing mounted on a special nut, It allows to achieve the required pressure by a lever length of 800 - 1000 mm. The optimal length of the arm and its diameter was determined experimentally using a specially designed hydromechanical unit. The result is a simple and technological design of the clamping device, easy to operate and provides the necessary pressure on the entire area of the joint of the conveyor belt. regulating and control unit provides: 1) automatically maintaining the heating temperature in the range of 140 - 150º C; 2) starting and stopping of the press; 3) an indication of the heaters via the LED indicators; 4) Protection against open circuit temperature sensors; 5) The overcurrent protection; 6) Protection against loss of control. Additionally, BRU performs junction box features a compartment for storing cables, connectors, and durable dust - moisture - protective housing with a convenient carrying handle as much as possible adapted to the most stringent conditions of operation, transportation and storage.
