Double-arc trough plate forming machine

Abstract

The invention provides a forming machine which can press a double-arc trough plate to be formed by one time, and solves the problems that the specifications of through plates of board type feeding machines are more and more, and specifications of the used presses are bigger and bigger. In the invention, an oil press with smaller tonnage is utilized for realizing the one-time-forming of large-specification trough plate transportation. The double-arc trough plate forming machine comprises a hydropress with an upper-die mould and a lower-die mould; the upper-die mould and the lower-die mould are arranged on a sliding machine and a fixing machine respectively; a forming upper die and a forming lower die are arranged on the upper-die mould and the lower-die mould respectively; and two ends of the forming surface of the forming upper die and two ends of the forming surface of the forming lower die are of two convex arc parts and two convex arc parts with different radiuses respectively.

Description

technical field [0001] The invention relates to forming equipment for a double-arc groove plate of an apron feeder. Background technique [0002] Apron feeder can be used in building materials, metallurgy, coal, chemical industry and other industries to transport various bulk or loose materials from storage bins to crushers, conveyors or other working machinery along the horizontal or inclined direction. Indispensable equipment in the process, especially suitable for running large and sharp materials. The conveyor trough is the main part of the apron feeder. The conveying trough of the plate feeder is in direct contact with the material to be conveyed, and the existing trough adopts double arc plates (see figure 1 ), with raised arcs of different radii front and back. When in use, for two adjacent slot plates, the large arc at the head of the back slot plate presses on the small arc at the tail of the front slot plate. With the increasing scale of modern projects, the sp...
