Abstract: A double inclined weld face structure for a jolt-and-vibration-free seamless rail with high bearing capacity relates to the welding of the seamless rail of the rail train, a weld seam of the rail according to the present application forms, at least partly, a double inclined weld face, forming an angle α with the vertical direction of the rail and an angle β with the transverse direction of the rail. The double inclined weld face can further improve the stress state in the weld face of the rail, enhance the bearing capacity of the weld face and eliminate upward and downward jolting and leftward and rightward shaking of a train. The double inclined weld faces of the two parallel rails (1) are arranged in a interleaving way and the interleaving length is greater than the length of a carriage, thus enhancing the running stability and durability of the train and more beneficial to use a simple existing Aluminothermic welding in the weld of the seamless rail.

Abstract: The present invention discloses an adjustable hydraulic press with both upper and lower double action, specially suitable for the cylindrical gear formed by stamping or expanding, closed forging and the metal cold forming or metal hot forming of punching, finishing, flanging and drawing of sheet materials. The press comprises four columns, an upper beam, a main slide block, a hold down slide block, a fixing worktable, a floating worktable and a lower beam. A hydraulic chamber a of master cylinder fixed in the upper beam communicates to a hydraulic chamber of an auxiliary cylinder, a plunger of the master cylinder is connected to the main slide block and drives it. A hydraulic chamber of a gas-liquid power accumulator fixed in the main slide block communicates to a hydraulic chamber of a hold down cylinder, a plunger of the hold down cylinder is connected to the hold down slide block and drives it. A plunger of an ejecting cylinder fixed in the lower beam is connected to the floating worktable and drives it. The hydraulic press of the invention simplifies the hydraulic system of the existing hydraulic, improves utilization rate of energy, production efficiency and working accuracy of workpiece.
